-
-## Installation
-
-### Go
-
-If you have a [Golang][golang] environment setup, you can simply run:
-
-```bash
-go get -u -v github.com/go-task/task/cmd/task
-```
-
-### Homebrew
-
-If you're on macOS and have [Homebrew][homebrew] installed, getting Task is
-as simple as running:
-
-```bash
-brew install go-task/tap/go-task
-```
-
-### Snap
-
-Task is available for [Snapcraft][snapcraft], but keep in mind that your
-Linux distribution should allow classic confinement for Snaps to Task work
-right:
-
-```bash
-sudo snap install task
-```
-
-### Install script
-
-We also have a [install script][installscript], which is very useful on
-scanarios like CIs. Many thanks to [godownloader][godownloader] for easily
-generating this script.
-
-```bash
-curl -s https://raw.githubusercontent.com/go-task/task/master/install-task.sh | sh
-```
-
-### Binary
-
-Or you can download the binary from the [releases][releases] page and add to
-your `PATH`. DEB and RPM packages are also available.
-The `task_checksums.txt` file contains the sha256 checksum for each file.
-
-## Usage
-
-Create a file called `Taskfile.yml` in the root of your project.
-The `cmds` attribute should contain the commands of a task.
-The example below allows compiling a Go app and uses [Minify][minify] to concat
-and minify multiple CSS files into a single one.
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - go build -v -i main.go
-
-  assets:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-Running the tasks is as simple as running:
-
-```bash
-task assets build
-```
-
-Task uses [github.com/mvdan/sh](https://github.com/mvdan/sh), a native Go sh
-interpreter. So you can write sh/bash commands and it will work even on
-Windows, where `sh` or `bash` are usually not available. Just remember any
-executable called must be available by the OS or in PATH.
-
-If you ommit a task name, "default" will be assumed.
-
-### Environment
-
-You can specify environment variables that are added when running a command:
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - echo $hallo
-    env:
-      hallo: welt
-```
-
-### OS specific task
-
-If you add a `Taskfile_{{GOOS}}.yml` you can override or amend your Taskfile
-based on the operating system.
-
-Example:
-
-Taskfile.yml:
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - echo "default"
-```
-
-Taskfile_linux.yml:
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - echo "linux"
-```
-
-Will print out `linux` and not `default`.
-
-Keep in mind that the version of the files should match. Also, when redefining
-a task the whole task is replaced, properties of the task are not merged.
-
-It's also possible to have an OS specific `Taskvars.yml` file, like
-`Taskvars_windows.yml`, `Taskfile_linux.yml`, or `Taskvars_darwin.yml`. See the
-[variables section](#variables) below.
-
-### Task directory
-
-By default, tasks will be executed in the directory where the Taskfile is
-located. But you can easily make the task run in another folder informing
-`dir`:
-
-```yml
-version: '2'
-
-tasks:
-  serve:
-    dir: public/www
-    cmds:
-      # run http server
-      - caddy
-```
-
-### Task dependencies
-
-You may have tasks that depend on others. Just pointing them on `deps` will
-make them run automatically before running the parent task:
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    deps: [assets]
-    cmds:
-      - go build -v -i main.go
-
-  assets:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-In the above example, `assets` will always run right before `build` if you run
-`task build`.
-
-A task can have only dependencies and no commands to group tasks together:
-
-```yml
-version: '2'
-
-tasks:
-  assets:
-    deps: [js, css]
-
-  js:
-    cmds:
-      - minify -o public/script.js src/js
-
-  css:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-If there is more than one dependency, they always run in parallel for better
-performance.
-
-If you want to pass information to dependencies, you can do that the same
-manner as you would to [call another task](#calling-another-task):
-
-```yml
-version: '2'
-
-tasks:
-  default:
-    deps:
-      - task: echo_sth
-        vars: {TEXT: "before 1"}
-      - task: echo_sth
-        vars: {TEXT: "before 2"}
-    cmds:
-      - echo "after"
-
-  echo_sth:
-    cmds:
-      - echo {{.TEXT}}
-```
-
-### Calling another task
-
-When a task has many dependencies, they are executed concurrently. This will
-often result in a faster build pipeline. But in some situations you may need
-to call other tasks serially. In this case, just use the following syntax:
-
-```yml
-version: '2'
-
-tasks:
-  main-task:
-    cmds:
-      - task: task-to-be-called
-      - task: another-task
-      - echo "Both done"
-
-  task-to-be-called:
-    cmds:
-      - echo "Task to be called"
-
-  another-task:
-    cmds:
-      - echo "Another task"
-```
-
-Overriding variables in the called task is as simple as informing `vars`
-attribute:
-
-```yml
-version: '2'
-
-tasks:
-  main-task:
-    cmds:
-      - task: write-file
-        vars: {FILE: "hello.txt", CONTENT: "Hello!"}
-      - task: write-file
-        vars: {FILE: "world.txt", CONTENT: "World!"}
-
-  write-file:
-    cmds:
-      - echo "{{.CONTENT}}" > {{.FILE}}
-```
-
-The above syntax is also supported in `deps`.
-
-### Prevent unnecessary work
-
-If a task generates something, you can inform Task the source and generated
-files, so Task will prevent to run them if not necessary.
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    deps: [js, css]
-    cmds:
-      - go build -v -i main.go
-
-  js:
-    cmds:
-      - minify -o public/script.js src/js
-    sources:
-      - src/js/**/*.js
-    generates:
-      - public/script.js
-
-  css:
-    cmds:
-      - minify -o public/style.css src/css
-    sources:
-      - src/css/**/*.css
-    generates:
-      - public/style.css
-```
-
-`sources` and `generates` can be files or file patterns. When both are given,
-Task will compare the modification date/time of the files to determine if it's
-necessary to run the task. If not, it will just print a message like
-`Task "js" is up to date`.
-
-If you prefer this check to be made by the content of the files, instead of
-its timestamp, just set the `method` property to `checksum`.
-You will probably want to ignore the `.task` folder in your `.gitignore` file
-(It's there that Task stores the last checksum).
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - go build .
-    sources:
-      - ./*.go
-    generates:
-      - app{{exeExt}}
-    method: checksum
-```
-
-> TIP: method `none` skips any validation and always run the task.
-
-Alternatively, you can inform a sequence of tests as `status`. If no error
-is returned (exit status 0), the task is considered up-to-date:
-
-```yml
-version: '2'
-
-tasks:
-  generate-files:
-    cmds:
-      - mkdir directory
-      - touch directory/file1.txt
-      - touch directory/file2.txt
-    # test existence of files
-    status:
-      - test -d directory
-      - test -f directory/file1.txt
-      - test -f directory/file2.txt
-```
-
-You can use `--force` or `-f` if you want to force a task to run even when
-up-to-date.
-
-Also, `task --status [tasks]...` will exit with a non-zero exit code if any of
-the tasks are not up-to-date.
-
-### Variables
-
-When doing interpolation of variables, Task will look for the below.
-They are listed below in order of importance (e.g. most important first):
-
-- Variables declared locally in the task
-- Variables given while calling a task from another.
-  (See [Calling another task](#calling-another-task) above)
-- Variables declared in the `vars:` option in the `Taskfile`
-- Variables available in the `Taskvars.yml` file
-- Environment variables
-
-Example of sending parameters with environment variables:
-
-```bash
-$ TASK_VARIABLE=a-value task do-something
-```
-
-Since some shells don't support above syntax to set environment variables
-(Windows) tasks also accepts a similar style when not in the beginning of
-the command. Variables given in this form are only visible to the task called
-right before.
-
-```bash
-$ task write-file FILE=file.txt "CONTENT=Hello, World!" print "MESSAGE=All done!"
-```
-
-Example of locally declared vars:
-
-```yml
-version: '2'
-
-tasks:
-  print-var:
-    cmds:
-      echo "{{.VAR}}"
-    vars:
-      VAR: Hello!
-```
-
-Example of global vars in a `Taskfile.yml`:
-
-```yml
-version: '2'
-
-vars:
-  GREETING: Hello from Taskfile!
-
-tasks:
-  greet:
-    cmds:
-      - echo "{{.GREETING}}"
-```
-
-Example of `Taskvars.yml` file:
-
-```yml
-PROJECT_NAME: My Project
-DEV_MODE: production
-GIT_COMMIT: {sh: git log -n 1 --format=%h}
-```
-
-#### Variables expansion
-
-Variables are expanded 2 times by default. You can change that by setting the
-`expansions:` option. Change that will be necessary if you compose many
-variables together:
-
-```yml
-version: '2'
-
-expansions: 3
-
-vars:
-  FOO: foo
-  BAR: bar
-  BAZ: baz
-  FOOBAR: "{{.FOO}}{{.BAR}}"
-  FOOBARBAZ: "{{.FOOBAR}}{{.BAZ}}"
-
-tasks:
-  default:
-    cmds:
-      - echo "{{.FOOBARBAZ}}"
-```
-
-#### Dynamic variables
-
-The below syntax (`sh:` prop in a variable) is considered a dynamic variable.
-The value will be treated as a command and the output assigned. If there is one
-or more trailing newlines, the last newline will be trimmed.
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    cmds:
-      - go build -ldflags="-X main.Version={{.GIT_COMMIT}}" main.go
-    vars:
-      GIT_COMMIT:
-        sh: git log -n 1 --format=%h
-```
-
-This works for all types of variables.
-
-### Go's template engine
-
-Task parse commands as [Go's template engine][gotemplate] before executing
-them. Variables are accessible through dot syntax (`.VARNAME`).
-
-All functions by the Go's [sprig lib](http://masterminds.github.io/sprig/)
-are available. The following example gets the current date in a given format:
-
-```yml
-version: '2'
-
-tasks:
-  print-date:
-    cmds:
-      - echo {{now | date "2006-01-02"}}
-```
-
-Task also adds the following functions:
-
-- `OS`: Returns operating system. Possible values are "windows", "linux",
-  "darwin" (macOS) and "freebsd".
-- `ARCH`: return the architecture Task was compiled to: "386", "amd64", "arm"
-  or "s390x".
-- `splitLines`: Splits Unix (\n) and Windows (\r\n) styled newlines.
-- `catLines`: Replaces Unix (\n) and Windows (\r\n) styled newlines with a space.
-- `toSlash`: Does nothing on Unix, but on Windows converts a string from `\`
-  path format to `/`.
-- `fromSlash`: Oposite of `toSlash`. Does nothing on Unix, but on Windows
-  converts a string from `\` path format to `/`.
-- `exeExt`: Returns the right executable extension for the current OS
-  (`".exe"` for Windows, `""` for others).
-
-Example:
-
-```yml
-version: '2'
-
-tasks:
-  print-os:
-    cmds:
-      - echo '{{OS}} {{ARCH}}'
-      - echo '{{if eq OS "windows"}}windows-command{{else}}unix-command{{end}}'
-      # This will be path/to/file on Unix but path\to\file on Windows
-      - echo '{{fromSlash "path/to/file"}}'
-  enumerated-file:
-    vars:
-      CONTENT: |
-        foo
-        bar
-    cmds:
-      - |
-        cat << EOF > output.txt
-        {{range $i, $line := .CONTENT | splitLines -}}
-        {{printf "%3d" $i}}: {{$line}}
-        {{end}}EOF
-```
-
-### Help
-
-Running `task --list` (or `task -l`) lists all tasks with a description.
-The following taskfile:
-
-```yml
-version: '2'
-
-tasks:
-  build:
-    desc: Build the go binary.
-    cmds:
-      - go build -v -i main.go
-
-  test:
-    desc: Run all the go tests.
-    cmds:
-      - go test -race ./...
-
-  js:
-    cmds:
-      - minify -o public/script.js src/js
-
-  css:
-    cmds:
-      - minify -o public/style.css src/css
-```
-
-would print the following output:
-
-```bash
-* build:   Build the go binary.
-* test:    Run all the go tests.
-```
-
-## Silent mode
-
-Silent mode disables echoing of commands before Task runs it.
-For the following Taskfile:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - echo "Print something"
-```
-
-Normally this will be print:
-
-```sh
-echo "Print something"
-Print something
-```
-
-With silent mode on, the below will be print instead:
-
-```sh
-Print something
-```
-
-There's three ways to enable silent mode:
-
-* At command level:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - cmd: echo "Print something"
-        silent: true
-```
-
-* At task level:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - echo "Print something"
-    silent: true
-```
-
-* Or globally with `--silent` or `-s` flag
-
-If you want to suppress stdout instead, just redirect a command to `/dev/null`:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - echo "This will print nothing" > /dev/null
-```
-
-## Dry run mode
-
-Dry run mode (`--dry`) compiles and steps through each task, printing the commands
-that would be run without executing them. This is useful for debugging your Taskfiles.
-
-## Ignore errors
-
-You have the option to ignore errors during command execution.
-Given the following Taskfile:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - exit 1
-      - echo "Hello World"
-```
-
-Task will abort the execution after running `exit 1` because the status code `1` stands for `EXIT_FAILURE`.
-However it is possible to continue with execution using `ignore_error`:
-
-```yml
-version: '2'
-
-tasks:
-  echo:
-    cmds:
-      - cmd: exit 1
-        ignore_error: true
-      - echo "Hello World"
-```
-
-`ignore_error` can also be set for a task, which mean errors will be supressed
-for all commands. But keep in mind this option won't propagate to other tasks
-called either by `deps` or `cmds`!
-
-## Output syntax
-
-By default, Task just redirect the STDOUT and STDERR of the running commands
-to the shell in real time. This is good for having live feedback for log
-printed by commands, but the output can become messy if you have multiple
-commands running at the same time and printing lots of stuff.
-
-To make this more customizable, there are currently three different output
-options you can choose:
-
-- `interleaved` (default)
-- `group`
-- `prefixed`
-
- To choose another one, just set it to root in the Taskfile:
-
- ```yml
-version: '2'
-
-output: 'group'
-
-tasks:
-  # ...
- ```
-
- The `group` output will print the entire output of a command once, after it
- finishes, so you won't have live feedback for commands that take a long time
- to run.
-
- The `prefix` output will prefix every line printed by a command with
- `[task-name] ` as the prefix, but you can customize the prefix for a command
- with the `prefix:` attribute:
-
- ```yml
-version: '2'
-
-output: prefixed
-
-tasks:
-  default:
-    deps:
-      - task: print
-        vars: {TEXT: foo}
-      - task: print
-        vars: {TEXT: bar}
-      - task: print
-        vars: {TEXT: baz}
-
-  print:
-    cmds:
-      - echo "{{.TEXT}}"
-    prefix: "print-{{.TEXT}}"
-    silent: true
-```
-
-```bash
-$ task default
-[print-foo] foo
-[print-bar] bar
-[print-baz] baz
-```
-
-## Watch tasks
-
-If you give a `--watch` or `-w` argument, task will watch for file changes
-and run the task again. This requires the `sources` attribute to be given,
-so task know which files to watch.
-
-## Examples
-
-The [go-task/examples][examples] intends to be a collection of Taskfiles for
-various use cases.
-(It still lacks many examples, though. Contributions are welcome).

+# Task
+
+Task is a task runner / build tool that aims to be simpler and easier to use
+than, for example, [GNU Make][make].
+
+Since it's written in [Go][go], Task is just a single binary and has no other
+dependencies, which means you don't need to mess with any complicated install
+setups just to use a build tool.
+
+Once [installed](installation.md), you just need to describe your build tasks
+using a simple [YAML][yaml] schema in a file called `Taskfile.yml`:
+
+```yaml
+version: '2'
+
+tasks:
+  hello:
+    cmds:
+      - echo 'Hello World from Task!'
+    silent: true
+```
+
+And call it by running `task hello` from you terminal.
+
+The above example is just the start, you can take a look at the [usage](usage.md)
+guide to check the full schema documentation and Task features.
+
+## Features
+
+- [Easy installation](installation.md): just download a single binary, add to
+  $PATH and you're done! Or you can also install using [Homebrew][homebrew] or
+  [Snapcraft][snapcraft] if you want;
+- Available on CIs: by adding [this simple command](installation.md#install-script)
+  to install on your CI script and you're done to use Task as part of your CI pipeline;
+- Truly cross-platform: while most build tools only work well on Linux or macOS,
+  Task also supports Windows thanks to [this awesome shell interpreter for Go][sh];
+- Great for code generation: you can easily [prevent a task from running](usage.md#prevent-unnecessary-work)
+  if a given set of files haven't changed since last run (based either on its
+  timestamp or content).

+# Installation
+
+## Binary
+
+Or you can download the binary from the [releases][releases] page and add to
+your $PATH. DEB and RPM packages are also available.
+The `task_checksums.txt` file contains the sha256 checksum for each file.
+
+## Homebrew
+
+If you're on macOS and have [Homebrew][homebrew] installed, getting Task is
+as simple as running:
+
+```bash
+brew install go-task/tap/go-task
+```
+
+## Snap
+
+Task is available for [Snapcraft][snapcraft], but keep in mind that your
+Linux distribution should allow classic confinement for Snaps to Task work
+right:
+
+```bash
+sudo snap install task
+```
+
+## Go
+
+Task now uses [Go Modules](https://github.com/golang/go/wiki/Modules), which
+means you may have trouble compiling it on older Go versions.
+
+For CI environments we recommend using the [Install Script](#install-script)
+instead, which is faster and more stable, since it'll just download the latest
+released binary, instead of compiling the edge (master branch) version.
+
+Installing in your `$GOPATH`:
+
+```bash
+go get -u -v github.com/go-task/task/cmd/task
+```
+
+Installing in another directory:
+
+```bash
+git clone https://github.com/go-task/task
+cd task
+
+# compiling binary to $GOPATH/bin
+go install -v
+
+# compiling it to another location
+# use -o ./task.exe on Windows
+go build -v -o ./task ./cmd/task
+```
+
+Both methods requires having the [Go][go] environment properly setup locally.
+
+## Install script
+
+We also have a [install script][installscript], which is very useful on
+scanarios like CIs. Many thanks to [godownloader][godownloader] for allowing
+easily generating this script.
+
+```bash
+curl -s https://taskfile.org/install.sh | sh
+```
+
+> This method will download the binary on the local `./bin` directory by default.

+# Usage
+
+## Getting started
+
+Create a file called `Taskfile.yml` in the root of your project.
+The `cmds` attribute should contain the commands of a task.
+The example below allows compiling a Go app and uses [Minify][minify] to concat
+and minify multiple CSS files into a single one.
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - go build -v -i main.go
+
+  assets:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+Running the tasks is as simple as running:
+
+```bash
+task assets build
+```
+
+Task uses [github.com/mvdan/sh](https://github.com/mvdan/sh), a native Go sh
+interpreter. So you can write sh/bash commands and it will work even on
+Windows, where `sh` or `bash` are usually not available. Just remember any
+executable called must be available by the OS or in PATH.
+
+If you ommit a task name, "default" will be assumed.
+
+## Environment
+
+You can specify environment variables that are added when running a command:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - echo $hallo
+    env:
+      hallo: welt
+```
+
+## Operating System specific tasks
+
+If you add a `Taskfile_{{GOOS}}.yml` you can override or amend your Taskfile
+based on the operating system.
+
+Example:
+
+Taskfile.yml:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - echo "default"
+```
+
+Taskfile_linux.yml:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - echo "linux"
+```
+
+Will print out `linux` and not `default`.
+
+Keep in mind that the version of the files should match. Also, when redefining
+a task the whole task is replaced, properties of the task are not merged.
+
+It's also possible to have an OS specific `Taskvars.yml` file, like
+`Taskvars_windows.yml`, `Taskfile_linux.yml`, or `Taskvars_darwin.yml`. See the
+[variables section](#variables) below.
+
+## Including other Taskfiles
+
+> This feature is still experimental and may have bugs.
+
+If you want to share tasks between different projects (Taskfiles), you can use
+the importing mechanism to include other Taskfiles using the `includes` keyword:
+
+```yaml
+version: '2'
+
+includes:
+  docs: ./documentation # will look for ./documentation/Taskfile.yml
+  docker: ./DockerTasks.yml
+```
+
+The tasks described in the given Taskfiles will be available with the informed
+namespace. So, you'd call `task docs:serve` to run the `serve` task from
+`documentation/Taskfile.yml` or `task docker:build` to run the `build` task
+from the `DockerTasks.yml` file.
+
+> The included Taskfiles must be using the same schema version the main
+> Taskfile uses.
+
+> Also, for now included Taskfiles can't include other Taskfiles.
+> This was a deliberate decision to keep use and implementation simple.
+> If you disagree, open an GitHub issue and explain your use case. =)
+
+## Task directory
+
+By default, tasks will be executed in the directory where the Taskfile is
+located. But you can easily make the task run in another folder informing
+`dir`:
+
+```yaml
+version: '2'
+
+tasks:
+  serve:
+    dir: public/www
+    cmds:
+      # run http server
+      - caddy
+```
+
+## Task dependencies
+
+You may have tasks that depend on others. Just pointing them on `deps` will
+make them run automatically before running the parent task:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    deps: [assets]
+    cmds:
+      - go build -v -i main.go
+
+  assets:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+In the above example, `assets` will always run right before `build` if you run
+`task build`.
+
+A task can have only dependencies and no commands to group tasks together:
+
+```yaml
+version: '2'
+
+tasks:
+  assets:
+    deps: [js, css]
+
+  js:
+    cmds:
+      - minify -o public/script.js src/js
+
+  css:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+If there is more than one dependency, they always run in parallel for better
+performance.
+
+If you want to pass information to dependencies, you can do that the same
+manner as you would to [call another task](#calling-another-task):
+
+```yaml
+version: '2'
+
+tasks:
+  default:
+    deps:
+      - task: echo_sth
+        vars: {TEXT: "before 1"}
+      - task: echo_sth
+        vars: {TEXT: "before 2"}
+    cmds:
+      - echo "after"
+
+  echo_sth:
+    cmds:
+      - echo {{.TEXT}}
+```
+
+## Calling another task
+
+When a task has many dependencies, they are executed concurrently. This will
+often result in a faster build pipeline. But in some situations you may need
+to call other tasks serially. In this case, just use the following syntax:
+
+```yaml
+version: '2'
+
+tasks:
+  main-task:
+    cmds:
+      - task: task-to-be-called
+      - task: another-task
+      - echo "Both done"
+
+  task-to-be-called:
+    cmds:
+      - echo "Task to be called"
+
+  another-task:
+    cmds:
+      - echo "Another task"
+```
+
+Overriding variables in the called task is as simple as informing `vars`
+attribute:
+
+```yaml
+version: '2'
+
+tasks:
+  main-task:
+    cmds:
+      - task: write-file
+        vars: {FILE: "hello.txt", CONTENT: "Hello!"}
+      - task: write-file
+        vars: {FILE: "world.txt", CONTENT: "World!"}
+
+  write-file:
+    cmds:
+      - echo "{{.CONTENT}}" > {{.FILE}}
+```
+
+The above syntax is also supported in `deps`.
+
+## Prevent unnecessary work
+
+If a task generates something, you can inform Task the source and generated
+files, so Task will prevent to run them if not necessary.
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    deps: [js, css]
+    cmds:
+      - go build -v -i main.go
+
+  js:
+    cmds:
+      - minify -o public/script.js src/js
+    sources:
+      - src/js/**/*.js
+    generates:
+      - public/script.js
+
+  css:
+    cmds:
+      - minify -o public/style.css src/css
+    sources:
+      - src/css/**/*.css
+    generates:
+      - public/style.css
+```
+
+`sources` and `generates` can be files or file patterns. When both are given,
+Task will compare the modification date/time of the files to determine if it's
+necessary to run the task. If not, it will just print a message like
+`Task "js" is up to date`.
+
+If you prefer this check to be made by the content of the files, instead of
+its timestamp, just set the `method` property to `checksum`.
+You will probably want to ignore the `.task` folder in your `.gitignore` file
+(It's there that Task stores the last checksum).
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - go build .
+    sources:
+      - ./*.go
+    generates:
+      - app{{exeExt}}
+    method: checksum
+```
+
+> TIP: method `none` skips any validation and always run the task.
+
+Alternatively, you can inform a sequence of tests as `status`. If no error
+is returned (exit status 0), the task is considered up-to-date:
+
+```yaml
+version: '2'
+
+tasks:
+  generate-files:
+    cmds:
+      - mkdir directory
+      - touch directory/file1.txt
+      - touch directory/file2.txt
+    # test existence of files
+    status:
+      - test -d directory
+      - test -f directory/file1.txt
+      - test -f directory/file2.txt
+```
+
+You can use `--force` or `-f` if you want to force a task to run even when
+up-to-date.
+
+Also, `task --status [tasks]...` will exit with a non-zero exit code if any of
+the tasks are not up-to-date.
+
+## Variables
+
+When doing interpolation of variables, Task will look for the below.
+They are listed below in order of importance (e.g. most important first):
+
+- Variables declared locally in the task
+- Variables given while calling a task from another.
+  (See [Calling another task](#calling-another-task) above)
+- Variables declared in the `vars:` option in the `Taskfile`
+- Variables available in the `Taskvars.yml` file
+- Environment variables
+
+Example of sending parameters with environment variables:
+
+```bash
+$ TASK_VARIABLE=a-value task do-something
+```
+
+Since some shells don't support above syntax to set environment variables
+(Windows) tasks also accepts a similar style when not in the beginning of
+the command. Variables given in this form are only visible to the task called
+right before.
+
+```bash
+$ task write-file FILE=file.txt "CONTENT=Hello, World!" print "MESSAGE=All done!"
+```
+
+Example of locally declared vars:
+
+```yaml
+version: '2'
+
+tasks:
+  print-var:
+    cmds:
+      echo "{{.VAR}}"
+    vars:
+      VAR: Hello!
+```
+
+Example of global vars in a `Taskfile.yml`:
+
+```yaml
+version: '2'
+
+vars:
+  GREETING: Hello from Taskfile!
+
+tasks:
+  greet:
+    cmds:
+      - echo "{{.GREETING}}"
+```
+
+Example of `Taskvars.yml` file:
+
+```yaml
+PROJECT_NAME: My Project
+DEV_MODE: production
+GIT_COMMIT: {sh: git log -n 1 --format=%h}
+```
+
+### Variables expansion
+
+Variables are expanded 2 times by default. You can change that by setting the
+`expansions:` option. Change that will be necessary if you compose many
+variables together:
+
+```yaml
+version: '2'
+
+expansions: 3
+
+vars:
+  FOO: foo
+  BAR: bar
+  BAZ: baz
+  FOOBAR: "{{.FOO}}{{.BAR}}"
+  FOOBARBAZ: "{{.FOOBAR}}{{.BAZ}}"
+
+tasks:
+  default:
+    cmds:
+      - echo "{{.FOOBARBAZ}}"
+```
+
+### Dynamic variables
+
+The below syntax (`sh:` prop in a variable) is considered a dynamic variable.
+The value will be treated as a command and the output assigned. If there is one
+or more trailing newlines, the last newline will be trimmed.
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    cmds:
+      - go build -ldflags="-X main.Version={{.GIT_COMMIT}}" main.go
+    vars:
+      GIT_COMMIT:
+        sh: git log -n 1 --format=%h
+```
+
+This works for all types of variables.
+
+## Go's template engine
+
+Task parse commands as [Go's template engine][gotemplate] before executing
+them. Variables are accessible through dot syntax (`.VARNAME`).
+
+All functions by the Go's [sprig lib](http://masterminds.github.io/sprig/)
+are available. The following example gets the current date in a given format:
+
+```yaml
+version: '2'
+
+tasks:
+  print-date:
+    cmds:
+      - echo {{now | date "2006-01-02"}}
+```
+
+Task also adds the following functions:
+
+- `OS`: Returns operating system. Possible values are "windows", "linux",
+  "darwin" (macOS) and "freebsd".
+- `ARCH`: return the architecture Task was compiled to: "386", "amd64", "arm"
+  or "s390x".
+- `splitLines`: Splits Unix (\n) and Windows (\r\n) styled newlines.
+- `catLines`: Replaces Unix (\n) and Windows (\r\n) styled newlines with a space.
+- `toSlash`: Does nothing on Unix, but on Windows converts a string from `\`
+  path format to `/`.
+- `fromSlash`: Oposite of `toSlash`. Does nothing on Unix, but on Windows
+  converts a string from `\` path format to `/`.
+- `exeExt`: Returns the right executable extension for the current OS
+  (`".exe"` for Windows, `""` for others).
+
+Example:
+
+```yaml
+version: '2'
+
+tasks:
+  print-os:
+    cmds:
+      - echo '{{OS}} {{ARCH}}'
+      - echo '{{if eq OS "windows"}}windows-command{{else}}unix-command{{end}}'
+      # This will be path/to/file on Unix but path\to\file on Windows
+      - echo '{{fromSlash "path/to/file"}}'
+  enumerated-file:
+    vars:
+      CONTENT: |
+        foo
+        bar
+    cmds:
+      - |
+        cat << EOF > output.txt
+        {{range $i, $line := .CONTENT | splitLines -}}
+        {{printf "%3d" $i}}: {{$line}}
+        {{end}}EOF
+```
+
+## Help
+
+Running `task --list` (or `task -l`) lists all tasks with a description.
+The following taskfile:
+
+```yaml
+version: '2'
+
+tasks:
+  build:
+    desc: Build the go binary.
+    cmds:
+      - go build -v -i main.go
+
+  test:
+    desc: Run all the go tests.
+    cmds:
+      - go test -race ./...
+
+  js:
+    cmds:
+      - minify -o public/script.js src/js
+
+  css:
+    cmds:
+      - minify -o public/style.css src/css
+```
+
+would print the following output:
+
+```bash
+* build:   Build the go binary.
+* test:    Run all the go tests.
+```
+
+## Silent mode
+
+Silent mode disables echoing of commands before Task runs it.
+For the following Taskfile:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - echo "Print something"
+```
+
+Normally this will be print:
+
+```sh
+echo "Print something"
+Print something
+```
+
+With silent mode on, the below will be print instead:
+
+```sh
+Print something
+```
+
+There's three ways to enable silent mode:
+
+* At command level:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - cmd: echo "Print something"
+        silent: true
+```
+
+* At task level:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - echo "Print something"
+    silent: true
+```
+
+* Or globally with `--silent` or `-s` flag
+
+If you want to suppress stdout instead, just redirect a command to `/dev/null`:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - echo "This will print nothing" > /dev/null
+```
+
+## Dry run mode
+
+Dry run mode (`--dry`) compiles and steps through each task, printing the commands
+that would be run without executing them. This is useful for debugging your Taskfiles.
+
+## Ignore errors
+
+You have the option to ignore errors during command execution.
+Given the following Taskfile:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - exit 1
+      - echo "Hello World"
+```
+
+Task will abort the execution after running `exit 1` because the status code `1` stands for `EXIT_FAILURE`.
+However it is possible to continue with execution using `ignore_error`:
+
+```yaml
+version: '2'
+
+tasks:
+  echo:
+    cmds:
+      - cmd: exit 1
+        ignore_error: true
+      - echo "Hello World"
+```
+
+`ignore_error` can also be set for a task, which mean errors will be supressed
+for all commands. But keep in mind this option won't propagate to other tasks
+called either by `deps` or `cmds`!
+
+## Output syntax
+
+By default, Task just redirect the STDOUT and STDERR of the running commands
+to the shell in real time. This is good for having live feedback for log
+printed by commands, but the output can become messy if you have multiple
+commands running at the same time and printing lots of stuff.
+
+To make this more customizable, there are currently three different output
+options you can choose:
+
+- `interleaved` (default)
+- `group`
+- `prefixed`
+
+To choose another one, just set it to root in the Taskfile:
+
+```yaml
+version: '2'
+
+output: 'group'
+
+tasks:
+  # ...
+```
+
+ The `group` output will print the entire output of a command once, after it
+ finishes, so you won't have live feedback for commands that take a long time
+ to run.
+
+ The `prefix` output will prefix every line printed by a command with
+ `[task-name] ` as the prefix, but you can customize the prefix for a command
+ with the `prefix:` attribute:
+
+ ```yaml
+version: '2'
+
+output: prefixed
+
+tasks:
+  default:
+    deps:
+      - task: print
+        vars: {TEXT: foo}
+      - task: print
+        vars: {TEXT: bar}
+      - task: print
+        vars: {TEXT: baz}
+
+  print:
+    cmds:
+      - echo "{{.TEXT}}"
+    prefix: "print-{{.TEXT}}"
+    silent: true
+```
+
+```bash
+$ task default
+[print-foo] foo
+[print-bar] bar
+[print-baz] baz
+```
+
+## Watch tasks
+
+If you give a `--watch` or `-w` argument, task will watch for file changes
+and run the task again. This requires the `sources` attribute to be given,
+so task know which files to watch.

+# SemVer
+
+The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
+
+* Parse semantic versions
+* Sort semantic versions
+* Check if a semantic version fits within a set of constraints
+* Optionally work with a `v` prefix
+
+[![Stability:
+Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
+[![Build Status](https://travis-ci.org/Masterminds/semver.svg)](https://travis-ci.org/Masterminds/semver) [![Build status](https://ci.appveyor.com/api/projects/status/jfk66lib7hb985k8/branch/master?svg=true&passingText=windows%20build%20passing&failingText=windows%20build%20failing)](https://ci.appveyor.com/project/mattfarina/semver/branch/master) [![GoDoc](https://godoc.org/github.com/Masterminds/semver?status.svg)](https://godoc.org/github.com/Masterminds/semver) [![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
+
+## Parsing Semantic Versions
+
+To parse a semantic version use the `NewVersion` function. For example,
+
+```go
+    v, err := semver.NewVersion("1.2.3-beta.1+build345")
+```
+
+If there is an error the version wasn't parseable. The version object has methods
+to get the parts of the version, compare it to other versions, convert the
+version back into a string, and get the original string. For more details
+please see the [documentation](https://godoc.org/github.com/Masterminds/semver).
+
+## Sorting Semantic Versions
+
+A set of versions can be sorted using the [`sort`](https://golang.org/pkg/sort/)
+package from the standard library. For example,
+
+```go
+    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+    vs := make([]*semver.Version, len(raw))
+	for i, r := range raw {
+		v, err := semver.NewVersion(r)
+		if err != nil {
+			t.Errorf("Error parsing version: %s", err)
+		}
+
+		vs[i] = v
+	}
+
+	sort.Sort(semver.Collection(vs))
+```
+
+## Checking Version Constraints
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+```go
+    c, err := semver.NewConstraint(">= 1.2.3")
+    if err != nil {
+        // Handle constraint not being parseable.
+    }
+
+    v, _ := semver.NewVersion("1.3")
+    if err != nil {
+        // Handle version not being parseable.
+    }
+    // Check if the version meets the constraints. The a variable will be true.
+    a := c.Check(v)
+```
+
+## Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of comma separated and comparisons. These are then separated by || separated or
+comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
+comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
+greater than or equal to 4.2.3.
+
+The basic comparisons are:
+
+* `=`: equal (aliased to no operator)
+* `!=`: not equal
+* `>`: greater than
+* `<`: less than
+* `>=`: greater than or equal to
+* `<=`: less than or equal to
+
+_Note, according to the Semantic Version specification pre-releases may not be
+API compliant with their release counterpart. It says,_
+
+> _A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version._
+
+_SemVer comparisons without a pre-release value will skip pre-release versions.
+For example, `>1.2.3` will skip pre-releases when looking at a list of values
+while `>1.2.3-alpha.1` will evaluate pre-releases._
+
+## Hyphen Range Comparisons
+
+There are multiple methods to handle ranges and the first is hyphens ranges.
+These look like:
+
+* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
+* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
+
+## Wildcards In Comparisons
+
+The `x`, `X`, and `*` characters can be used as a wildcard character. This works
+for all comparison operators. When used on the `=` operator it falls
+back to the pack level comparison (see tilde below). For example,
+
+* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `>= 1.2.x` is equivalent to `>= 1.2.0`
+* `<= 2.x` is equivalent to `<= 3`
+* `*` is equivalent to `>= 0.0.0`
+
+## Tilde Range Comparisons (Patch)
+
+The tilde (`~`) comparison operator is for patch level ranges when a minor
+version is specified and major level changes when the minor number is missing.
+For example,
+
+* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
+* `~1` is equivalent to `>= 1, < 2`
+* `~2.3` is equivalent to `>= 2.3, < 2.4`
+* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `~1.x` is equivalent to `>= 1, < 2`
+
+## Caret Range Comparisons (Major)
+
+The caret (`^`) comparison operator is for major level changes. This is useful
+when comparisons of API versions as a major change is API breaking. For example,
+
+* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
+* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
+* `^2.3` is equivalent to `>= 2.3, < 3`
+* `^2.x` is equivalent to `>= 2.0.0, < 3`
+
+# Validation
+
+In addition to testing a version against a constraint, a version can be validated
+against a constraint. When validation fails a slice of errors containing why a
+version didn't meet the constraint is returned. For example,
+
+```go
+    c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
+    if err != nil {
+        // Handle constraint not being parseable.
+    }
+
+    v, _ := semver.NewVersion("1.3")
+    if err != nil {
+        // Handle version not being parseable.
+    }
+
+    // Validate a version against a constraint.
+    a, msgs := c.Validate(v)

+# Sprig: Template functions for Go templates
+[![Stability: Sustained](https://masterminds.github.io/stability/sustained.svg)](https://masterminds.github.io/stability/sustained.html)
+[![Build Status](https://travis-ci.org/Masterminds/sprig.svg?branch=master)](https://travis-ci.org/Masterminds/sprig)
+
+The Go language comes with a [built-in template
+language](http://golang.org/pkg/text/template/), but not
+very many template functions. This library provides a group of commonly
+used template functions.
+
+It is inspired by the template functions found in
+[Twig](http://twig.sensiolabs.org/documentation) and also in various
+JavaScript libraries, such as [underscore.js](http://underscorejs.org/).
+
+## Usage
+
+Template developers can read the [Sprig function documentation](http://masterminds.github.io/sprig/) to
+learn about the >100 template functions available.
+
+For Go developers wishing to include Sprig as a library in their programs,
+API documentation is available [at GoDoc.org](http://godoc.org/github.com/Masterminds/sprig), but
+read on for standard usage.
+
+### Load the Sprig library
+
+To load the Sprig `FuncMap`:
+
+```go
+
+import (
+  "github.com/Masterminds/sprig"
+  "html/template"
+)
+
+// This example illustrates that the FuncMap *must* be set before the
+// templates themselves are loaded.
+tpl := template.Must(
+  template.New("base").Funcs(sprig.FuncMap()).ParseGlob("*.html")
+)
+
+
+```
+
+### Call the functions inside of templates
+
+By convention, all functions are lowercase. This seems to follow the Go
+idiom for template functions (as opposed to template methods, which are
+TitleCase).
+
+
+Example:
+
+```
+{{ "hello!" | upper | repeat 5 }}
+```
+
+Produces:
+
+```
+HELLO!HELLO!HELLO!HELLO!HELLO!
+```
+
+## Principles:
+
+The following principles were used in deciding on which functions to add, and
+determining how to implement them.
+
+- Template functions should be used to build layout. Therefore, the following
+  types of operations are within the domain of template functions:
+  - Formatting
+  - Layout
+  - Simple type conversions
+  - Utilities that assist in handling common formatting and layout needs (e.g. arithmetic)
+- Template functions should not return errors unless there is no way to print
+  a sensible value. For example, converting a string to an integer should not
+  produce an error if conversion fails. Instead, it should display a default
+  value that can be displayed.
+- Simple math is necessary for grid layouts, pagers, and so on. Complex math
+  (anything other than arithmetic) should be done outside of templates.
+- Template functions only deal with the data passed into them. They never retrieve
+  data from a source.
+- Finally, do not override core Go template functions.

-Date Functions
-
-	- date FORMAT TIME: Format a date, where a date is an integer type or a time.Time type, and
-	  format is a time.Format formatting string.
-	- dateModify: Given a date, modify it with a duration: `date_modify "-1.5h" now`. If the duration doesn't
-	  parse, it returns the time unaltered. See `time.ParseDuration` for info on duration strings.
-	- now: Current time.Time, for feeding into date-related functions.
-	- htmlDate TIME: Format a date for use in the value field of an HTML "date" form element.
-	- dateInZone FORMAT TIME TZ: Like date, but takes three arguments: format, timestamp,
-	  timezone.
-	- htmlDateInZone TIME TZ: Like htmlDate, but takes two arguments: timestamp,
-	  timezone.
-
-String Functions
-
-	- abbrev: Truncate a string with ellipses. `abbrev 5 "hello world"` yields "he..."
-	- abbrevboth: Abbreviate from both sides, yielding "...lo wo..."
-	- trunc: Truncate a string (no suffix). `trunc 5 "Hello World"` yields "hello".
-	- trim: strings.TrimSpace
-	- trimAll: strings.Trim, but with the argument order reversed `trimAll "$" "$5.00"` or `"$5.00 | trimAll "$"`
-	- trimSuffix: strings.TrimSuffix, but with the argument order reversed: `trimSuffix "-" "ends-with-"`
-	- trimPrefix: strings.TrimPrefix, but with the argument order reversed `trimPrefix "$" "$5"`
-	- upper: strings.ToUpper
-	- lower: strings.ToLower
-	- nospace: Remove all space characters from a string. `nospace "h e l l o"` becomes "hello"
-	- title: strings.Title
-	- untitle: Remove title casing
-	- repeat: strings.Repeat, but with the arguments switched: `repeat count str`. (This simplifies common pipelines)
-	- substr: Given string, start, and length, return a substr.
-	- initials: Given a multi-word string, return the initials. `initials "Matt Butcher"` returns "MB"
-	- randAlphaNum: Given a length, generate a random alphanumeric sequence
-	- randAlpha: Given a length, generate an alphabetic string
-	- randAscii: Given a length, generate a random ASCII string (symbols included)
-	- randNumeric: Given a length, generate a string of digits.
-	- swapcase: SwapCase swaps the case of a string using a word based algorithm. see https://godoc.org/github.com/Masterminds/goutils#SwapCase
-	- shuffle: Shuffle randomizes runes in a string and returns the result. It uses default random source in `math/rand`
-	- snakecase: convert all upper case characters in a string to underscore format.
-	- camelcase: convert all lower case characters behind underscores to upper case character
-	- wrap: Force a line wrap at the given width. `wrap 80 "imagine a longer string"`
-	- wrapWith: Wrap a line at the given length, but using 'sep' instead of a newline. `wrapWith 50, "<br>", $html`
-	- contains: strings.Contains, but with the arguments switched: `contains substr str`. (This simplifies common pipelines)
-	- hasPrefix: strings.hasPrefix, but with the arguments switched
-	- hasSuffix: strings.hasSuffix, but with the arguments switched
-	- quote: Wrap string(s) in double quotation marks, escape the contents by adding '\' before '"'.
-	- squote: Wrap string(s) in double quotation marks, does not escape content.
-	- cat: Concatenate strings, separating them by spaces. `cat $a $b $c`.
-	- indent: Indent a string using space characters. `indent 4 "foo\nbar"` produces "    foo\n    bar"
-	- nindent: Indent a string using space characters and prepend a new line. `indent 4 "foo\nbar"` produces "\n    foo\n    bar"
-	- replace: Replace an old with a new in a string: `$name | replace " " "-"`
-	- plural: Choose singular or plural based on length: `len $fish | plural "one anchovy" "many anchovies"`
-	- sha256sum: Generate a hex encoded sha256 hash of the input
-	- toString: Convert something to a string
-
-String Slice Functions:
-
-	- join: strings.Join, but as `join SEP SLICE`
-	- split: strings.Split, but as `split SEP STRING`. The results are returned
-	  as a map with the indexes set to _N, where N is an integer starting from 0.
-	  Use it like this: `{{$v := "foo/bar/baz" | split "/"}}{{$v._0}}` (Prints `foo`)
-	- splitList: strings.Split, but as `split SEP STRING`. The results are returned
-	  as an array.
-	- toStrings: convert a list to a list of strings. 'list 1 2 3 | toStrings' produces '["1" "2" "3"]'
-	- sortAlpha: sort a list lexicographically.
-
-Integer Slice Functions:
-
-	- until: Given an integer, returns a slice of counting integers from 0 to one
-	  less than the given integer: `range $i, $e := until 5`
-	- untilStep: Given start, stop, and step, return an integer slice starting at
-	  'start', stopping at `stop`, and incrementing by 'step. This is the same
-	  as Python's long-form of 'range'.
-
-Conversions:
-
-	- atoi: Convert a string to an integer. 0 if the integer could not be parsed.
-	- int64: Convert a string or another numeric type to an int64.
-	- int: Convert a string or another numeric type to an int.
-	- float64: Convert a string or another numeric type to a float64.
-
-Defaults:
-
-	- default: Give a default value. Used like this: trim "   "| default "empty".
-	  Since trim produces an empty string, the default value is returned. For
-	  things with a length (strings, slices, maps), len(0) will trigger the default.
-	  For numbers, the value 0 will trigger the default. For booleans, false will
-	  trigger the default. For structs, the default is never returned (there is
-	  no clear empty condition). For everything else, nil value triggers a default.
-	- empty: Return true if the given value is the zero value for its type.
-	  Caveats: structs are always non-empty. This should match the behavior of
-	  {{if pipeline}}, but can be used inside of a pipeline.
-	- coalesce: Given a list of items, return the first non-empty one.
-	  This follows the same rules as 'empty'. '{{ coalesce .someVal 0 "hello" }}`
-	  will return `.someVal` if set, or else return "hello". The 0 is skipped
-	  because it is an empty value.
-	- compact: Return a copy of a list with all of the empty values removed.
-	  'list 0 1 2 "" | compact' will return '[1 2]'
-	- ternary: Given a value,'true | ternary "b" "c"' will return "b".
-	  'false | ternary "b" "c"' will return '"c"'. Similar to the JavaScript ternary
-	  operator.
-
-OS:
-	- env: Resolve an environment variable
-	- expandenv: Expand a string through the environment
-
-File Paths:
-	- base: Return the last element of a path. https://golang.org/pkg/path#Base
-	- dir: Remove the last element of a path. https://golang.org/pkg/path#Dir
-	- clean: Clean a path to the shortest equivalent name.  (e.g. remove "foo/.."
-	  from "foo/../bar.html") https://golang.org/pkg/path#Clean
-	- ext: https://golang.org/pkg/path#Ext
-	- isAbs: https://golang.org/pkg/path#IsAbs
-
-Encoding:
-	- b64enc: Base 64 encode a string.
-	- b64dec: Base 64 decode a string.
-
-Reflection:
-
-	- typeOf: Takes an interface and returns a string representation of the type.
-	  For pointers, this will return a type prefixed with an asterisk(`*`). So
-	  a pointer to type `Foo` will be `*Foo`.
-	- typeIs: Compares an interface with a string name, and returns true if they match.
-	  Note that a pointer will not match a reference. For example `*Foo` will not
-	  match `Foo`.
-	- typeIsLike: Compares an interface with a string name and returns true if
-	  the interface is that `name` or that `*name`. In other words, if the given
-	  value matches the given type or is a pointer to the given type, this returns
-	  true.
-	- kindOf: Takes an interface and returns a string representation of its kind.
-	- kindIs: Returns true if the given string matches the kind of the given interface.
-
-	Note: None of these can test whether or not something implements a given
-	interface, since doing so would require compiling the interface in ahead of
-	time.
-
-Data Structures:
-
-	- tuple: Takes an arbitrary list of items and returns a slice of items. Its
-	  tuple-ish properties are mainly gained through the template idiom, and not
-	  through an API provided here. WARNING: The implementation of tuple will
-	  change in the future.
-	- list: An arbitrary ordered list of items. (This is prefered over tuple.)
-	- dict: Takes a list of name/values and returns a map[string]interface{}.
-	  The first parameter is converted to a string and stored as a key, the
-	  second parameter is treated as the value. And so on, with odds as keys and
-	  evens as values. If the function call ends with an odd, the last key will
-	  be assigned the empty string. Non-string keys are converted to strings as
-	  follows: []byte are converted, fmt.Stringers will have String() called.
-	  errors will have Error() called. All others will be passed through
-	  fmt.Sprintf("%v").
-
-Lists Functions:
-
-These are used to manipulate lists: '{{ list 1 2 3 | reverse | first }}'
-
-	- first: Get the first item in a 'list'. 'list 1 2 3 | first' prints '1'
-	- last: Get the last item in a 'list': 'list 1 2 3 | last ' prints '3'
-	- rest: Get all but the first item in a list: 'list 1 2 3 | rest' returns '[2 3]'
-	- initial: Get all but the last item in a list: 'list 1 2 3 | initial' returns '[1 2]'
-	- append: Add an item to the end of a list: 'append $list 4' adds '4' to the end of '$list'
-	- prepend: Add an item to the beginning of a list: 'prepend $list 4' puts 4 at the beginning of the list.
-	- reverse: Reverse the items in a list.
-	- uniq: Remove duplicates from a list.
-	- without: Return a list with the given values removed: 'without (list 1 2 3) 1' would return '[2 3]'
-	- has: Return 'true' if the item is found in the list: 'has "foo" $list' will return 'true' if the list contains "foo"
-
-Dict Functions:
-
-These are used to manipulate dicts.
-
-	- set: Takes a dict, a key, and a value, and sets that key/value pair in
-	  the dict. `set $dict $key $value`. For convenience, it returns the dict,
-	  even though the dict was modified in place.
-	- unset: Takes a dict and a key, and deletes that key/value pair from the
-	  dict. `unset $dict $key`. This returns the dict for convenience.
-	- hasKey: Takes a dict and a key, and returns boolean true if the key is in
-	  the dict.
-	- pluck: Given a key and one or more maps, get all of the values for that key.
-	- keys: Get an array of all of the keys in one or more dicts.
-	- pick: Select just the given keys out of the dict, and return a new dict.
-	- omit: Return a dict without the given keys.
-	- values: Returns a list (interface{}) of all dictionary values.
-
-Math Functions:
-
-Integer functions will convert integers of any width to `int64`. If a
-string is passed in, functions will attempt to convert with
-`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.
-
-	- add1: Increment an integer by 1
-	- add: Sum an arbitrary number of integers
-	- sub: Subtract the second integer from the first
-	- div: Divide the first integer by the second
-	- mod: Module of first integer divided by second
-	- mul: Multiply integers
-	- max: Return the biggest of a series of one or more integers
-	- min: Return the smallest of a series of one or more integers
-	- biggest: DEPRECATED. Return the biggest of a series of one or more integers
-
-Crypto Functions:
-
-	- genPrivateKey: Generate a private key for the given cryptosystem. If no
-	  argument is supplied, by default it will generate a private key using
-	  the RSA algorithm. Accepted values are `rsa`, `dsa`, and `ecdsa`.
-	- derivePassword: Derive a password from the given parameters according to the ["Master Password" algorithm](http://masterpasswordapp.com/algorithm.html)
-	  Given parameters (in order) are:
-          `counter` (starting with 1), `password_type` (maximum, long, medium, short, basic, or pin), `password`,
-           `user`, and `site`
-
-SemVer Functions:
-
-These functions provide version parsing and comparisons for SemVer 2 version
-strings.
-
-	- semver: Parse a semantic version and return a Version object.
-	- semverCompare: Compare a SemVer range to a particular version.
+See http://masterminds.github.io/sprig/ for more detailed documentation on each of the available functions.

+===========
+[![Stability: Maintenance](https://masterminds.github.io/stability/maintenance.svg)](https://masterminds.github.io/stability/maintenance.html)
+[![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils) [![Build Status](https://travis-ci.org/Masterminds/goutils.svg?branch=master)](https://travis-ci.org/Masterminds/goutils) [![Build status](https://ci.appveyor.com/api/projects/status/sc2b1ew0m7f0aiju?svg=true)](https://ci.appveyor.com/project/mattfarina/goutils)
+
+
+GoUtils provides users with utility functions to manipulate strings in various ways. It is a Go implementation of some
+string manipulation libraries of Java Apache Commons. GoUtils includes the following Java Apache Commons classes:
+* WordUtils    
+* RandomStringUtils  
+* StringUtils (partial implementation)
+
+## Installation
+If you have Go set up on your system, from the GOPATH directory within the command line/terminal, enter this:
+
+	go get github.com/Masterminds/goutils
+
+If you do not have Go set up on your system, please follow the [Go installation directions from the documenation](http://golang.org/doc/install), and then follow the instructions above to install GoUtils.
+
+
+## Documentation
+GoUtils doc is available here: [![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils)
+
+
+## Usage
+The code snippets below show examples of how to use GoUtils. Some functions return errors while others do not. The first instance below, which does not return an error, is the `Initials` function (located within the `wordutils.go` file).
+
+    package main
+
+    import (
+        "fmt"
+    	"github.com/Masterminds/goutils"
+    )
+
+    func main() {
+
+    	// EXAMPLE 1: A goutils function which returns no errors
+        fmt.Println (goutils.Initials("John Doe Foo")) // Prints out "JDF"
+
+    }
+Some functions return errors mainly due to illegal arguements used as parameters. The code example below illustrates how to deal with function that returns an error. In this instance, the function is the `Random` function (located within the `randomstringutils.go` file).
+
+    package main
+
+    import (
+        "fmt"
+        "github.com/Masterminds/goutils"
+    )
+
+    func main() {
+
+        // EXAMPLE 2: A goutils function which returns an error
+        rand1, err1 := goutils.Random (-1, 0, 0, true, true)  
+
+        if err1 != nil {
+			fmt.Println(err1) // Prints out error message because -1 was entered as the first parameter in goutils.Random(...)
+		} else {
+			fmt.Println(rand1)
+		}
+
+    }

+The uuid package generates and inspects UUIDs based on
+[RFC 4122](http://tools.ietf.org/html/rfc4122)
+and DCE 1.1: Authentication and Security Services. 
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid).  It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice.  One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).

+# Contributing #
+
+Thanks for your contribution in advance. No matter what you will contribute to this project, pull request or bug report or feature discussion, it's always highly appreciated.
+
+## New API or feature ##
+
+I want to speak more about how to add new functions to this package.
+
+Package `xstring` is a collection of useful string functions which should be implemented in Go. It's a bit subject to say which function should be included and which should not. I set up following rules in order to make it clear and as objective as possible.
+
+* Rule 1: Only string algorithm, which takes string as input, can be included.
+* Rule 2: If a function has been implemented in package `string`, it must not be included.
+* Rule 3: If a function is not language neutral, it must not be included.
+* Rule 4: If a function is a part of standard library in other languages, it can be included.
+* Rule 5: If a function is quite useful in some famous framework or library, it can be included.
+
+New function must be discussed in project issues before submitting any code. If a pull request with new functions is sent without any ref issue, it will be rejected.
+
+## Pull request ##
+
+Pull request is always welcome. Just make sure you have run `go fmt` and all test cases passed before submit.
+
+If the pull request is to add a new API or feature, don't forget to update README.md and add new API in function list.

+[![GoDoc](https://godoc.org/github.com/huandu/xstrings?status.svg)](https://godoc.org/github.com/huandu/xstrings)
+
+Go package [xstrings](https://godoc.org/github.com/huandu/xstrings) is a collection of string functions, which are widely used in other languages but absent in Go package [strings](http://golang.org/pkg/strings).
+
+All functions are well tested and carefully tuned for performance.
+
+## Propose a new function ##
+
+Please review [contributing guideline](CONTRIBUTING.md) and [create new issue](https://github.com/huandu/xstrings/issues) to state why it should be included.
+
+## Install ##
+
+Use `go get` to install this library.
+
+	go get github.com/huandu/xstrings
+
+## API document ##
+
+See [GoDoc](https://godoc.org/github.com/huandu/xstrings) for full document.
+
+## Function list ##
+
+Go functions have a unique naming style. One, who has experience in other language but new in Go, may have difficulties to find out right string function to use.
+
+Here is a list of functions in [strings](http://golang.org/pkg/strings) and [xstrings](https://godoc.org/github.com/huandu/xstrings) with enough extra information about how to map these functions to their friends in other languages. Hope this list could be helpful for fresh gophers.

+# Mergo
+
+A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
+
+Also a lovely [comune](http://en.wikipedia.org/wiki/Mergo) (municipality) in the Province of Ancona in the Italian region of Marche.
+
+## Status
+
+It is ready for production use. [It is used in several projects by Docker, Google, The Linux Foundation, VMWare, Shopify, etc](https://github.com/imdario/mergo#mergo-in-the-wild).

+### Latest release
+
+[Release v0.3.6](https://github.com/imdario/mergo/releases/tag/v0.3.6).
+
+### Important note
+
+Please keep in mind that in [0.3.2](//github.com/imdario/mergo/releases/tag/0.3.2) Mergo changed `Merge()`and `Map()` signatures to support [transformers](#transformers). An optional/variadic argument has been added, so it won't break existing code.
+
+If you were using Mergo **before** April 6th 2015, please check your project works as intended after updating your local copy with ```go get -u github.com/imdario/mergo```. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause (I hope it won't!) in existing projects after the change (release 0.2.0).

+## Installation
+
+    go get github.com/imdario/mergo
+
+    // use in your .go code
+    import (
+        "github.com/imdario/mergo"
+    )
+
+## Usage
+
+You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as [they are not considered zero values](https://golang.org/ref/spec#The_zero_value) either. Also maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
+
+```go
+if err := mergo.Merge(&dst, src); err != nil {
+    // ...
+}
+```
+
+Also, you can merge overwriting values using the transformer `WithOverride`.
+
+```go
+if err := mergo.Merge(&dst, src, mergo.WithOverride); err != nil {
+    // ...
+}
+```
+
+Additionally, you can map a `map[string]interface{}` to a struct (and otherwise, from struct to map), following the same restrictions as in `Merge()`. Keys are capitalized to find each corresponding exported field.
+
+```go
+if err := mergo.Map(&dst, srcMap); err != nil {
+    // ...
+}
+```
+
+Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as `map[string]interface{}`. They will be just assigned as values.
+
+More information and examples in [godoc documentation](http://godoc.org/github.com/imdario/mergo).
+
+### Nice example
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/imdario/mergo"
+)
+
+type Foo struct {
+	A string
+	B int64
+}
+
+func main() {
+	src := Foo{
+		A: "one",
+		B: 2,
+	}
+	dest := Foo{
+		A: "two",
+	}
+	mergo.Merge(&dest, src)
+	fmt.Println(dest)
+	// Will print
+	// {two 2}
+}
+```
+
+Note: if test are failing due missing package, please execute:
+
+    go get gopkg.in/yaml.v2
+
+### Transformers
+
+Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, `time.Time` is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero `time.Time`?
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/imdario/mergo"
+        "reflect"
+        "time"
+)
+
+type timeTransfomer struct {
+}
+
+func (t timeTransfomer) Transformer(typ reflect.Type) func(dst, src reflect.Value) error {
+	if typ == reflect.TypeOf(time.Time{}) {
+		return func(dst, src reflect.Value) error {
+			if dst.CanSet() {
+				isZero := dst.MethodByName("IsZero")
+				result := isZero.Call([]reflect.Value{})
+				if result[0].Bool() {
+					dst.Set(src)
+				}
+			}
+			return nil
+		}
+	}
+	return nil
+}
+
+type Snapshot struct {
+	Time time.Time
+	// ...
+}
+
+func main() {
+	src := Snapshot{time.Now()}
+	dest := Snapshot{}
+	mergo.Merge(&dest, src, mergo.WithTransformers(timeTransfomer{}))
+	fmt.Println(dest)
+	// Will print
+	// { 2018-01-12 01:15:00 +0000 UTC m=+0.000000001 }
+}
+```

+# go-homedir
+
+This is a Go library for detecting the user's home directory without
+the use of cgo, so the library can be used in cross-compilation environments.
+
+Usage is incredibly simple, just call `homedir.Dir()` to get the home directory
+for a user, and `homedir.Expand()` to expand the `~` in a path to the home
+directory.
+
+**Why not just use `os/user`?** The built-in `os/user` package requires
+cgo on Darwin systems. This means that any Go code that uses that package
+cannot cross compile. But 99% of the time the use for `os/user` is just to
+retrieve the home directory, which we can do for the current user without
+cgo. This library does that, enabling cross-compilation.

+# watcher
+
+[![Build Status](https://travis-ci.org/radovskyb/watcher.svg?branch=master)](https://travis-ci.org/radovskyb/watcher)
+
+`watcher` is a Go package for watching for files or directory changes (recursively or non recursively) without using filesystem events, which allows it to work cross platform consistently.
+
+`watcher` watches for changes and notifies over channels either anytime an event or an error has occurred.
+
+Events contain the `os.FileInfo` of the file or directory that the event is based on and the type of event and file or directory path.
+
+[Installation](#installation)  
+[Features](#features)  
+[Example](#example)  
+[Contributing](#contributing)  
+[Watcher Command](#command)  
+
+# Update
+Event.Path for Rename and Move events is now returned in the format of `fromPath -> toPath`
+
+#### Chmod event is not supported under windows.
+
+# Installation
+
+```shell
+go get -u github.com/radovskyb/watcher/...
+```
+
+# Features
+
+- Customizable polling interval.
+- Filter Events.
+- Watch folders recursively or non-recursively.
+- Choose to ignore hidden files.
+- Choose to ignore specified files and folders.
+- Notifies the `os.FileInfo` of the file that the event is based on. e.g `Name`, `ModTime`, `IsDir`, etc.
+- Notifies the full path of the file that the event is based on or the old and new paths if the event was a `Rename` or `Move` event.
+- Limit amount of events that can be received per watching cycle.
+- List the files being watched.
+- Trigger custom events.
+
+# Todo
+
+- Write more tests.
+- Write benchmarks.
+
+# Example
+
+```go
+package main
+
+import (
+	"fmt"
+	"log"
+	"time"
+
+	"github.com/radovskyb/watcher"
+)
+
+func main() {
+	w := watcher.New()
+
+	// SetMaxEvents to 1 to allow at most 1 event's to be received
+	// on the Event channel per watching cycle.
+	//
+	// If SetMaxEvents is not set, the default is to send all events.
+	w.SetMaxEvents(1)
+
+	// Only notify rename and move events.
+	w.FilterOps(watcher.Rename, watcher.Move)
+
+	go func() {
+		for {
+			select {
+			case event := <-w.Event:	
+				fmt.Println(event) // Print the event's info.
+			case err := <-w.Error:
+				log.Fatalln(err)
+			case <-w.Closed:
+				return
+			}
+		}
+	}()
+
+	// Watch this folder for changes.
+	if err := w.Add("."); err != nil {
+		log.Fatalln(err)
+	}
+
+	// Watch test_folder recursively for changes.
+	if err := w.AddRecursive("../test_folder"); err != nil {
+		log.Fatalln(err)
+	}
+
+	// Print a list of all of the files and folders currently
+	// being watched and their paths.
+	for path, f := range w.WatchedFiles() {
+		fmt.Printf("%s: %s\n", path, f.Name())
+	}
+
+	fmt.Println()
+
+	// Trigger 2 events after watcher started.
+	go func() {
+		w.Wait()
+		w.TriggerEvent(watcher.Create, nil)
+		w.TriggerEvent(watcher.Remove, nil)
+	}()
+
+	// Start the watching process - it'll check for changes every 100ms.
+	if err := w.Start(time.Millisecond * 100); err != nil {
+		log.Fatalln(err)
+	}
+}
+```
+
+# Contributing
+If you would ike to contribute, simply submit a pull request.
+
+# Command
+
+`watcher` comes with a simple command which is installed when using the `go get` command from above.
+
+# Usage
+
+```
+Usage of watcher:
+  -cmd string
+    	command to run when an event occurs
+  -dotfiles
+    	watch dot files (default true)
+  -interval string
+    	watcher poll interval (default "100ms")
+  -keepalive
+    	keep alive when a cmd returns code != 0
+  -list
+    	list watched files on start
+  -pipe
+    	pipe event's info to command's stdin
+  -recursive
+    	watch folders recursively (default true)
+  -startcmd
+    	run the command when watcher starts
+```
+
+All of the flags are optional and watcher can also be called by itself:
+```shell
+watcher
+```
+(watches the current directory recursively for changes and notifies any events that occur.)
+
+A more elaborate example using the `watcher` command:
+```shell
+watcher -dotfiles=false -recursive=false -cmd="./myscript" main.go ../
+```
+In this example, `watcher` will ignore dot files and folders and won't watch any of the specified folders recursively. It will also run the script `./myscript` anytime an event occurs while watching `main.go` or any files or folders in the previous directory (`../`).
+
+Using the `pipe` and `cmd` flags together will send the event's info to the command's stdin when changes are detected.
+
+First create a file called `script.py` with the following contents:
+```python
+import sys
+
+for line in sys.stdin:
+	print (line + " - python")
+```
+
+Next, start watcher with the `pipe` and `cmd` flags enabled:
+```shell
+watcher -cmd="python script.py" -pipe=true
+```
+
+Now when changes are detected, the event's info will be output from the running python script.

+## Description
+
+pflag is a drop-in replacement for Go's flag package, implementing
+POSIX/GNU-style --flags.
+
+pflag is compatible with the [GNU extensions to the POSIX recommendations
+for command-line options][1]. For a more precise description, see the
+"Command-line flag syntax" section below.
+
+[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+pflag is available under the same style of BSD license as the Go language,
+which can be found in the LICENSE file.
+
+## Installation
+
+pflag is available using the standard `go get` command.
+
+Install by running:
+
+    go get github.com/spf13/pflag
+
+Run tests by running:
+
+    go test github.com/spf13/pflag
+
+## Usage
+
+pflag is a drop-in replacement of Go's native flag package. If you import
+pflag under the name "flag" then all code should continue to function
+with no changes.
+
+``` go
+import flag "github.com/spf13/pflag"
+```
+
+There is one exception to this: if you directly instantiate the Flag struct
+there is one more field "Shorthand" that you will need to set.
+Most code never instantiates this struct directly, and instead uses
+functions such as String(), BoolVar(), and Var(), and is therefore
+unaffected.
+
+Define flags using flag.String(), Bool(), Int(), etc.
+
+This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
+
+``` go
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+```
+
+If you like, you can bind the flag to a variable using the Var() functions.
+
+``` go
+var flagvar int
+func init() {
+    flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
+}
+```
+
+Or you can create custom flags that satisfy the Value interface (with
+pointer receivers) and couple them to flag parsing by
+
+``` go
+flag.Var(&flagVal, "name", "help message for flagname")
+```
+
+For such flags, the default value is just the initial value of the variable.
+
+After all flags are defined, call
+
+``` go
+flag.Parse()
+```
+
+to parse the command line into the defined flags.
+
+Flags may then be used directly. If you're using the flags themselves,
+they are all pointers; if you bind to variables, they're values.
+
+``` go
+fmt.Println("ip has value ", *ip)
+fmt.Println("flagvar has value ", flagvar)
+```
+
+There are helpers function to get values later if you have the FlagSet but
+it was difficult to keep up with all of the flag pointers in your code.
+If you have a pflag.FlagSet with a flag called 'flagname' of type int you
+can use GetInt() to get the int value. But notice that 'flagname' must exist
+and it must be an int. GetString("flagname") will fail.
+
+``` go
+i, err := flagset.GetInt("flagname")
+```
+
+After parsing, the arguments after the flag are available as the
+slice flag.Args() or individually as flag.Arg(i).
+The arguments are indexed from 0 through flag.NArg()-1.
+
+The pflag package also defines some new functions that are not in flag,
+that give one-letter shorthands for flags. You can use these by appending
+'P' to the name of any function that defines a flag.
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+var flagvar bool
+func init() {
+	flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
+}
+flag.VarP(&flagVal, "varname", "v", "help message")
+```
+
+Shorthand letters can be used with single dashes on the command line.
+Boolean shorthand flags can be combined with other shorthand flags.
+
+The default set of command-line flags is controlled by
+top-level functions.  The FlagSet type allows one to define
+independent sets of flags, such as to implement subcommands
+in a command-line interface. The methods of FlagSet are
+analogous to the top-level functions for the command-line
+flag set.
+
+## Setting no option default values for flags
+
+After you create a flag it is possible to set the pflag.NoOptDefVal for
+the given flag. Doing this changes the meaning of the flag slightly. If
+a flag has a NoOptDefVal and the flag is set on the command line without
+an option the flag will be set to the NoOptDefVal. For example given:
+
+``` go
+var ip = flag.IntP("flagname", "f", 1234, "help message")
+flag.Lookup("flagname").NoOptDefVal = "4321"
+```
+
+Would result in something like
+
+| Parsed Arguments | Resulting Value |
+| -------------    | -------------   |
+| --flagname=1357  | ip=1357         |
+| --flagname       | ip=4321         |
+| [nothing]        | ip=1234         |
+
+## Command line flag syntax
+
+```
+--flag    // boolean flags, or flags with no option default values
+--flag x  // only on flags without a default value
+--flag=x
+```
+
+Unlike the flag package, a single dash before an option means something
+different than a double dash. Single dashes signify a series of shorthand
+letters for flags. All but the last shorthand letter must be boolean flags
+or a flag with a default value
+
+```
+// boolean or flags where the 'no option default value' is set
+-f
+-f=true
+-abc
+but
+-b true is INVALID
+
+// non-boolean and flags without a 'no option default value'
+-n 1234
+-n=1234
+-n1234
+
+// mixed
+-abcs "hello"
+-absd="hello"
+-abcs1234
+```
+
+Flag parsing stops after the terminator "--". Unlike the flag package,
+flags can be interspersed with arguments anywhere on the command line
+before this terminator.
+
+Integer flags accept 1234, 0664, 0x1234 and may be negative.
+Boolean flags (in their long form) accept 1, 0, t, f, true, false,
+TRUE, FALSE, True, False.
+Duration flags accept any input valid for time.ParseDuration.
+
+## Mutating or "Normalizing" Flag names
+
+It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow.
+
+**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag
+
+``` go
+func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+	from := []string{"-", "_"}
+	to := "."
+	for _, sep := range from {
+		name = strings.Replace(name, sep, to, -1)
+	}
+	return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc)
+```
+
+**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name
+
+``` go
+func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
+	switch name {
+	case "old-flag-name":
+		name = "new-flag-name"
+		break
+	}
+	return pflag.NormalizedName(name)
+}
+
+myFlagSet.SetNormalizeFunc(aliasNormalizeFunc)
+```
+
+## Deprecating a flag or its shorthand
+It is possible to deprecate a flag, or just its shorthand. Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used.
+
+**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead.
+```go
+// deprecate a flag by specifying its name and a usage message
+flags.MarkDeprecated("badflag", "please use --good-flag instead")
+```
+This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used.
+
+**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n".
+```go
+// deprecate a flag shorthand by specifying its flag name and a usage message
+flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only")
+```
+This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used.
+
+Note that usage message is essential here, and it should not be empty.
+
+## Hidden flags
+It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
+
+**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
+```go
+// hide a flag by specifying its name
+flags.MarkHidden("secretFlag")
+```
+
+## Disable sorting of flags
+`pflag` allows you to disable sorting of flags for help and usage message.
+
+**Example**:
+```go
+flags.BoolP("verbose", "v", false, "verbose output")
+flags.String("coolflag", "yeaah", "it's really cool flag")
+flags.Int("usefulflag", 777, "sometimes it's very useful")
+flags.SortFlags = false
+flags.PrintDefaults()
+```
+**Output**:
+```
+  -v, --verbose           verbose output
+      --coolflag string   it's really cool flag (default "yeaah")
+      --usefulflag int    sometimes it's very useful (default 777)
+```
+
+
+## Supporting Go flags when using pflag
+In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
+to support flags defined by third-party dependencies (e.g. `golang/glog`).
+
+**Example**: You want to add the Go flags to the `CommandLine` flagset
+```go
+import (
+	goflag "flag"
+	flag "github.com/spf13/pflag"
+)
+
+var ip *int = flag.Int("flagname", 1234, "help message for flagname")
+
+func main() {
+	flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
+	flag.Parse()
+}
+```
+
