+
+Ahoy is a command line tool that gives each of your projects its own CLI app with zero code and dependencies.
+
+Write your commands in a YAML file and then Ahoy gives you lots of features like:
+- a command listing
+- per-command help text
+- command tab completion
+- run commands from any subdirectory
+
+Ahoy makes it easy to create aliases and templates for commands that are useful. It was created to help with running interactive commands within Docker containers, but it's just as useful for local commands, commands over `ssh`, or really anything that could be run from the command line in a single clean interface.
+
+## Examples
+
+Say you want to import a MySQL database running in `docker-compose` using another container called `cli`. The command could look like this:
+
+`docker exec -i $(docker-compose ps -q cli) bash -c 'mysql -u$DB_ENV_MYSQL_USER -p$DB_ENV_MYSQL_PASSWORD -h$DB_PORT_3306_TCP_ADDR $DB_ENV_MYSQL_DATABASE' < some-database.sql`
+
+With Ahoy, you can turn this into:
+
+`ahoy mysql-import < some-database.sql`
+
+## Quick Start
+
+Get started immediately with our comprehensive examples file:
+
+```bash
+# Create a new project with example commands
+ahoy init
+
+# Or download the examples file directly
+curl -o .ahoy.yml https://raw.githubusercontent.com/ahoy-cli/ahoy/master/examples/examples.ahoy.yml
+```
+
+The examples file includes **30+ usable example commands** for:
+- **Local Development Environments** - `up`, `down`, `restart`, `status`
+- **Testing & Quality** - `test`, `lint` with multi-language support
+- **Database Operations** - `db`, `db:backup` for MySQL/PostgreSQL
+- **Build & Deployment** - `build`, `deploy` with safety checks
+- **Drupal Integration** - `drush`, `cr`, `uli`, `cex`, `cim` for Drupal projects
+
+**🔍 [View the complete examples file →](examples/examples.ahoy.yml)**
+
+Try it out:
+```bash
+ahoy status # Show service status
+ahoy urls # Show available URLs
+ahoy shell # Open a shell in your container
+```
+
+## Features
+
+- Non-invasive - Use your existing workflow! It can wrap commands and scripts you are already using.
+- Consistent - Commands always run relative to the `.ahoy.yml` file, but can be called from any subfolder.
+- Visual - See a list of all your commands in one place, along with helpful descriptions.
+- Flexible - Commands are specific to a single folder tree, so each repo/workspace can have its own commands.
+- Command templates - Use regular `bash` syntax like `"$@"` for all arguments, or `$1` for the first argument.
+- Fully interactive - Your shells (like MySQL) and prompts still work.
+- Import multiple config files using the "imports" field.
+- Uses the "last in wins" rule to deal with duplicate commands amongst the config files.
+- [Command aliases](#command-aliases) - oft-used or long commands can have aliases.
+- Use a different entrypoint (the thing that runs your commands) if you wish, instead of `bash`. E.g. using PHP, Node.js, Python, etc. is possible.
+- Plugins are possible by overriding the entrypoint.
+- Self-documenting - Commands and help declared in `.ahoy.yml` show up as ahoy command help and [shell completion](#shell-autocompletions) of commands (see [bash/zsh completion](https://ahoy-cli.readthedocs.io/en/latest/#bash-zsh-completion)) is also available. We now have a dedicated Zsh plugin for completions at [ahoy-cli/zsh-ahoy](https://github.com/ahoy-cli/zsh-ahoy).
+- Support for [environment variables](#environment-variables) at both file and command level using the `env` field
+- Environment variables from a global file are loaded first, then command-specific variables override them
+- Environment files use standard shell format with one variable per line, comments supported
+
+## Installation
+
+### macOS
+
+Using Homebrew / Linuxbrew:
+
+```
+brew install ahoy
+```
+
+### Linux
+
+Download the [latest release from GitHub](https://github.com/ahoy-cli/ahoy/releases), move the appropriate binary for your plaform into someplace in your $PATH and rename it `ahoy`.
+
+Example:
+```
+os=$(uname -s | tr '[:upper:]' '[:lower:]') && architecture=$(case $(uname -m) in x86_64 | amd64) echo "amd64" ;; aarch64 | arm64 | armv8) echo "arm64" ;; *) echo "amd64" ;; esac) && sudo wget -q https://github.com/ahoy-cli/ahoy/releases/latest/download/ahoy-bin-$os-$architecture -O /usr/local/bin/ahoy && sudo chown $USER /usr/local/bin/ahoy && chmod +x /usr/local/bin/ahoy
+```
+
+### Windows
+
+For WSL2, use the Linux binary above for your architecture.
+
+## Environment Variables
+
+Ahoy supports loading environment variables from files at both global and command levels, with support for multiple environment files.
+
+#### Single Environment File (backwards compatible):
+
+```yaml
+ahoyapi: v2
+
+# Global environment file relative to .ahoy.yml
+env: .env
+
+commands:
+ db-import:
+ # Command-specific environment file, overrides global vars
+ env: .env.db
+ usage: Import a database
+ cmd: mysql -u$DB_USER -p$DB_PASSWORD $DB_NAME < $1
+```
+
+#### Multiple Environment Files (new feature):
+
+```yaml
+ahoyapi: v2
+
+# Multiple global environment files loaded in order
+env:
+ - .env.base
+ - .env.local
+ - .env.override
+
+commands:
+ deploy:
+ # Multiple command-specific env files
+ env:
+ - .env.deploy
+ - .env.secrets
+ usage: Deploy the application
+ cmd: ./deploy.sh
+```
+
+#### Environment File Format:
+```sh
+# Global .env file
+DB_USER=root
+DB_PASSWORD=root
+
+# Command-specific .env.db file
+DB_USER=custom_user
+DB_PASSWORD=secret
+DB_NAME=mydb
+```
+
+**Key Features:**
+- Files are loaded in order, with later files overriding earlier ones
+- Command-level env files override global env files
+- Non-existent files are gracefully ignored
+- Supports comments and empty lines in env files
+- Maintains full backwards compatibility with single file syntax
+
+## Command Aliases
+
+Ahoy now supports command aliases. This feature allows you to define alternative names for your commands, making them more convenient to use and remember.
+
+### Usage
+
+In your `.ahoy.yml` file, you can add an `aliases` field to any command definition. The `aliases` field should be an array of strings, each representing one or more alternative names for the command.
+
+Example:
+
+```yaml
+ahoyapi: v2
+commands:
+ hello:
+ usage: Say hello
+ cmd: echo "Hello, World!"
+ aliases: ["hi", "greet"]
+```
+
+In this example, the `hello` command can also be invoked using `hi` or `greet`.
+
+### Benefits
+
+- Improved usability: Users can call commands using shorter or more intuitive names.
+- Flexibility: You can provide multiple ways to access the same functionality without duplicating command definitions.
+- Backward compatibility: You can introduce new, more descriptive command names while keeping old names as aliases.
+
+### Notes
+
+- Aliases are displayed in the help output for each command.
+- Bash completion works with aliases as well as primary command names.
+- **If multiple commands share the same alias, the "last in wins" rule is used and the last matching command will be executed.**
+
+## Shell autocompletions
+
+### Zsh
+
+For Zsh completions, we have a standalone plugin available at [ahoy-cli/zsh-ahoy](https://github.com/ahoy-cli/zsh-ahoy).
+
+### Bash
+
+For Bash, you'll need to make sure you have bash-completion installed and setup. See [bash/zsh completion](https://ahoy-cli.readthedocs.io/en/latest/#bash-zsh-completion) for further instructions.
+
+## Example of the YAML file setup
+
+```YAML
+# All files must have v2 set or you'll get an error
+ahoyapi: v2
+
+# You can now override the entrypoint. This is the default if you don't override it.
+# {{cmd}} is replaced with your command and {{name}} is the name of the command that was run (available as $0)
+entrypoint:
+ - bash
+ - "-c"
+ - '{{cmd}}'
+ - '{{name}}'
+commands:
+ simple-command:
+ usage: An example of a single-line command.
+ cmd: echo "Do stuff with bash"
+
+ complex-command:
+ usage: Show more advanced features.
+ cmd: | # We support multi-line commands with pipes.
+ echo "multi-line bash script";
+ # You can call other ahoy commands.
+ ahoy simple-command
+ # you can take params
+ echo "your params were: $@"
+ # you can use numbered params, same as bash.
+ echo "param1: $1"
+ echo "param2: $2"
+ # Everything bash supports is available, if statements, etc.
+ # Hate bash? Use something else like python in a subscript or change the entrypoint.
+
+ subcommands:
+ usage: List the commands from the imported config files.
+ # These commands will be aggregated together with later files overriding earlier ones if they exist.
+ imports:
+ - ./some-file1.ahoy.yml
+ - ./some-file2.ahoy.yml
+ - ./some-file3.ahoy.yml
+```
+
+## Planned Features
+
+- Enable specifying specific arguments and flags in the ahoy file itself to cut down on parsing arguments in scripts.
+- Support for more built-in commands or a "verify" YAML option that would create a yes / no prompt for potentially destructive commands. (Are you sure you want to delete all your containers?)
+- Pipe tab completion to another command (allows you to get tab completion).
+- Support for configuration.

+Some things to keep in mind when using ahoy:
+
+* **You always need a .ahoy.yml file** - This is where ahoy gets it's configuration. If the current directory doesn't have that file, it will recursively look at all the parent directories for one until it either finds it, or fails with an error. This means that each project should have an ahoy file at it's root to work, but you can be in any subdirectory and ahoy will still find the right file.
+* **Commands are always run from the directory where .ahoy.yml is** - That's really helpful because no matter where you run ahoy from, the commands will be run from a consistent directory.
+* **Bash is what is actually running the commands** - everything that's within a "cmd" definition is piped into bash, so whatever you can do with bash, you can do in an ahoy command if you want to create something more complex than a single one-line command. This also means that each command runs in a bash subshell, which is usually fine since all environment variables are copied in, but you won't be able to affect the parent shell.. for example, changing the user's current directory or ENV variables.
+* **Easily debug using --verbose** - You can always get the details of what's actually being run in a command with the -v or the --verbose flag.
+* **Subcommands come from imported ahoy.yml files** - You can import another command files that use the ahoy yaml format as subcommands. This is useful to split up types of commands into different files and so the list of commands isn't as long. For example, we do this with the dkan command, which just imports dkan/.ahoy/dkan.ahoy.yml. All those commands are then listed by typing `ahoy dkan`
+* **Ahoy uses the {{args}} placeholder with a commands arguments** - Similar to Drupal templates, ANY arguments added after a command are passed into {{args}}. If you use {{args}} in your command, the actual arguments will be swapped out before the command is run. If {{args}} is used multiple times in a command, all instances are replaced. This is necessary so we can pass arguments along into the script, but adds a lot of flexibility.
+* **You can use ahoy commands within other commands** - This is really powerful! You can define helper commands to further abstract where commands are run (ie. locally vs ssh, vs docker), or simple utilities like ahoy confirm "question that will prompt the user for a yes or no answer" . You can think of these kind of like reusable functions. If you want to hide these utility commands, you can set `hide: true` in your ahoy file.
+* **Quotes can be tricky** - Sometimes when passing one command into subcommands, you might "loose" your quotes. Try using --verbose to debug what's happening first, and experiment with both single and double quotes. Keep in mind how the yaml spec processes and escapes quotes. We recommend not starting your command with quotes unless necessary. Multi-line commands (scripts) are best done using `cmd: |` which allows you to use multiple lines without worrying about quotes.
+* **Using Environment variables** - You can use environment variables from within ahoy commands, but you sometimes need to pay attention to quotes, especially if the ENV variable you intend to use is from another machine (docker, ssh).
+* **Check your yaml formatting** - The script will check your yaml formatting and throw an error if it's not right, but it doesn't check everything. Make sure your whitespace and structure are correct if you get yaml errors.

+
+## Basics
+The simplest way to start using ahoy is to create a basic .ahoy.yml file in your current directory like so:
+```Yaml
+ahoyapi: v1
+usage: DKAN cli app for development using ahoy.
+commands:
+ echo:
+ usage: Simply echo all the arguments
+ # Note that {{args}} will be replaced with the string of all arguments passed
+ cmd: echo "{{args}}"
+```
+
+Now if we simply run ahoy, it will find that file and output the help text and a list of commands.
+```
+$ ahoy
+NAME:
+ ahoy - DKAN cli app for development using ahoy.
+USAGE:
+ ahoy [global options] command [command options] [arguments...]
+COMMANDS:
+ echo Simply echo all the arguments
+ init Initialize a new .ahoy.yml config file in the current directory.
+GLOBAL OPTIONS:
+ --verbose, -v Output extra details like the commands to be run. [$AHOY_VERBOSE]
+ --file, -f Use a specific ahoy file.
+ --help, -h show help
+ --version print the version
+ --generate-bash-completion
+VERSION:
+ 0.0.0
+```
+Now if we call `ahoy -v echo "Do I hear an echo?"` ..
+```
+ahoy -v echo "Do I hear an echo?"
+2016/01/13 14:03:54 ===> Ahoy echo from : echo "Do I hear an echo?"
+Do I hear an echo?
+```
+
+### Writing More Complex Commands
+Let's show an example of using bash scripts AND reusing ahoy commands
+```Yaml
+ahoyapi: v1
+commands:
+ confirm:
+ cmd: |
+ read -r -p "{{args}} [y/N] " response
+ if [ $response = y ]; then
+ true
+ else
+ false
+ fi
+ # This will keep the confirm command from showing up in the help text.
+ hide: true
+ meaning-of-life:
+ cmd: |
+ ahoy confirm "Are you sure you want to know?" &&
+ # Run this if confirm returns true
+ echo The meaning of life is 42 ||
+ # Run this if confirm returns false
+ echo "OK, you don't want to know, skipping..."
+```
+```
+$ ahoy meaning-of-life
+Are you sure you want to know? [y/N] y
+The meaning of life is 42
+
+$ ahoy meaning-of-life
+Are you sure you want to know? [y/N] n
+OK, you don't want to know, skipping...
+```
+
+##Importing commands from other ahoy files.
+
+Another powerful feature is importing commands from other files.
+###Subcommands
+Ahoy allows you to import an entire yml file full of commands by using `import: relative path to file` instead of `cmd`. This is useful to organize commands into groups.
+###Direct import
+You can also import single commands by calling ahoy and setting the path of the .ahoy file you want to use using the -f flag.
+```Yaml
+#sub.ahoy.yml
+ahoyapi: v1
+commands:
+ whoami:
+ #Simple unix command that displays the logged in user.
+ cmd: whoami
+```
+```Yaml
+#.ahoy.yml
+ahoyapi: v1
+commands:
+ # Imports a single ahoy command called whoami and changes the name to direct example
+ direct-example:
+ usage: Runs the whoami command directly
+ cmd: ahoy -f sub.ahoy.yml whoami
+ # Imports all commands in the file
+ import-example:
+ usage: Loads all commands in a subfile.
+ import: sub.ahoy.yml
+```
+```
+$ ahoy direct-example
+fcarey #or whatever your user name is
+
+$ ahoy import-example whoami
+fcarey #or whatever your user name is
+
+#Shows help text for imported subcommands
+$ahoy import-example
+NAME:
+ ahoy - Creates a configurable cli app for running commands.
+USAGE:
+ ahoy [global options] command [command options] [arguments...]
+COMMANDS:
+ whoami
+ init Initialize a new .ahoy.yml config file in the current directory.
+GLOBAL OPTIONS:
+ --verbose, -v Output extra details like the commands to be run. [$AHOY_VERBOSE]
+ --file, -f Use a specific ahoy file.
+ --help, -h show help
+ --version print the version
+ --generate-bash-completion
+VERSION:

+# Ahoy! - Automate and organize your workflows, no matter what technology you use.
+
+Ahoy is command line tool that gives each of your projects their own CLI app with with zero code and dependencies.
+
+Simply write your commands in a yaml file and ahoy gives you lots of features like:
+* a command listing
+* per-command help text
+* command tab completion
+* run commands from any subdirectory
+
+Essentially, ahoy makes is easy to create aliases and templates for commands that are useful. It was specifically created to help with running interactive commands within docker containers, but it's just as useful for local commands, commands over ssh, or really anything that could be run from the command line in a single clean interface.
+
+## Examples
+
+Say you want to import a sql database running in docker-compose using another container called cli. The command could look like this:
+
+`docker exec -i $(docker-compose ps -q cli) bash -c 'mysql -u$DB_ENV_MYSQL_USER -p$DB_ENV_MYSQL_PASSWORD -h$DB_PORT_3306_TCP_ADDR $DB_ENV_MYSQL_DATABASE' < some-database.sql`
+
+With ahoy, you can turn this into
+
+`ahoy mysql-import < some-database.sql`
+
+[More Examples](Home.html)
+
+## FEATURES
+- Non-invasive - Use your existing workflow! It can wrap commands and scripts you are already using.
+- Consitent - Commands always run relative to the .ahoy.yml file, but can be called from any subfolder.
+- Visual - See a list of all of your commands in one place, along with helpful descriptions.
+- Flexible - Commands are specific to a single folder tree, so each repo/workspace can have its own commands
+- Command Templates - Args can be dropped into your commands using `{{args}}`
+- Fully interactive - your shells (like mysql) and prompts still work.
+- Self-Documenting - Commands and help declared in .ahoy.yml show up as ahoy command help and bash completion of commands (see below)
+
+## INSTALLATION
+
+### OSX
+Using Homebrew:
+```
+brew tap ahoy-cli/tap
+brew install ahoy
+# For v2 which is still alpha (see below)
+brew install ahoy --HEAD
+```
+
+### Linux
+Download and unzip the latest release and move the appropriate binary for your plaform into someplace in your $PATH and rename it `ahoy`
+
+Example:
+```
+sudo wget -q https://github.com/ahoy-cli/ahoy/releases/download/1.1.0/ahoy-`uname -s`-amd64 -O /usr/local/bin/ahoy && sudo chown $USER /usr/local/bin/ahoy && chmod +x /usr/local/bin/ahoy
+# For v2
+sudo wget -q https://github.com/ahoy-cli/ahoy/releases/download/2.0.0/ahoy-bin-`uname -s`-amd64 -O /usr/local/bin/ahoy && sudo chown $USER /usr/local/bin/ahoy && chmod +x /usr/local/bin/ahoy
+```
+
+## Autocompletions
+
+### Zsh
+For Zsh completions, we have a standalone plugin available at [ahoy-cli/zsh-ahoy](https://github.com/ahoy-cli/zsh-ahoy).
+
+### Bash
+
+For Bash, you'll need to make sure you have bash-completion installed and setup. On OSX with homebrew it looks like this:
+
+`brew install bash bash-completion`
+
+Now make sure you follow the couple installation instructions in the "Caveats" section that homebrew returns. And make sure completion is working for git for instance before you continue (you may need to restart your shell)
+
+Then, (for homebrew) you'll want to create a file at `/usr/local/etc/bash_completion.d/ahoy` with the following:
+
+```Bash
+#! /bin/bash
+
+: ${PROG:=$(basename ${BASH_SOURCE})}
+
+_cli_bash_autocomplete() {
+ local cur opts base
+ COMPREPLY=()
+ cur="${COMP_WORDS[COMP_CWORD]}"
+ opts=$( ${COMP_WORDS[@]:0:$COMP_CWORD} --generate-bash-completion )
+ COMPREPLY=( $(compgen -W "${opts}" -- ${cur}) )
+ return 0
+ }
+
+ complete -F _cli_bash_autocomplete $PROG
+```
+
+restart your shell, and you should see ahoy autocomplete when typing `ahoy [TAB]`
+
+## USAGE
+Almost all the commands are actually specified in a .ahoy.yml file placed in your working tree somewhere. Commands that are added there show up as options in ahoy. Here is what it looks like when using the [example.ahoy.yml file](https://github.com/ahoy-cli/ahoy/blob/master/examples/examples.ahoy.yml). To start with this file locally you can run `ahoy init`.
+
+```
+$ ahoy
+NAME:
+ ahoy - Send commands to docker-compose services
+
+USAGE:
+ ahoy [global options] command [command options] [arguments...]
+
+VERSION:
+ 0.0.0
+
+COMMANDS:
+ vdown Stop the vagrant box if one exists.
+ vup Start the vagrant box if one exists.

+## Version 2
+
+All new features are being added to the v2 (master) branch of ahoy which is still in alpha and will have breaking changes with v1 ahoy files, so to use ahoy v2, you'll need to do the following:
+- Upgrade to the ahoy v2 binary which currently needs to be compiled from source. If you are using homebrew, you can use that to upgrade to v2 using the following:
+```
+ brew uninstall ahoy # Required or you'll get errors
+ brew upgrade # Updates the tap
+ brew install ahoy --HEAD # Installs ahoy by compiling the latest from the master branch
+ ahoy # You should see full version that you're using.
+```
+- Change your `ahoyapi: v1` lines to `ahoyapi: v2`
+
+### New Features in v2
+- Implements a new feature to import mulitple config files using the "imports" field.
+- Uses the "last in wins" rule to deal with duplicate commands amongst the config files.
+
+```
+commands:
+ list:
+ usage: List the commands from the imported config files.
+ imports:
+ - ./confirmation.ahoy.yml
+ - ./docker.ahoy.yml
+ - ./examples.ahoy.yml
+```
+
+### Planned v2 features
+- Provide "drivers" or "plugins" for bash, docker-compose, kubernetes (these systems still work now, this would just make it easier)
+- Do specific arg replacement like {{arg1}} and enable specifying specific arguments and flags in the ahoy file itself to cut down on parsing arguments in scripts.
+- Support for more built-in commands or a "verify" yaml option that would create a yes / no prompt for potentially destructive commands. (Are you sure you want to delete all your containers?)
+- Pipe tab completion to another command (allows you to get tab completion)

+# mousetrap
+
+mousetrap is a tiny library that answers a single question.
+
+On a Windows machine, was the process invoked by someone double clicking on
+the executable file while browsing in explorer?
+
+### Motivation
+
+Windows developers unfamiliar with command line tools will often "double-click"
+the executable for a tool. Because most CLI tools print the help and then exit
+when invoked without arguments, this is often very frustrating for those users.
+
+mousetrap provides a way to detect these invocations so that you can provide
+more helpful behavior and instructions on how to run the CLI tool. To see what
+this looks like, both from an organizational and a technical perspective, see
+https://inconshreveable.com/09-09-2014/sweat-the-small-stuff/
+
+### The interface
+
+The library exposes a single interface:
+
+ func StartedByExplorer() (bool)

+## Cobra User Contract
+
+### Versioning
+Cobra will follow a steady release cadence. Non breaking changes will be released as minor versions quarterly. Patch bug releases are at the discretion of the maintainers. Users can expect security patch fixes to be released within relatively short order of a CVE becoming known. For more information on security patch fixes see the CVE section below. Releases will follow [Semantic Versioning](https://semver.org/). Users tracking the Master branch should expect unpredictable breaking changes as the project continues to move forward. For stability, it is highly recommended to use a release.
+
+### Backward Compatibility
+We will maintain two major releases in a moving window. The N-1 release will only receive bug fixes and security updates and will be dropped once N+1 is released.
+
+### Deprecation
+Deprecation of Go versions or dependent packages will only occur in major releases. To reduce the change of this taking users by surprise, any large deprecation will be preceded by an announcement in the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) and an Issue on Github.
+
+### CVE
+Maintainers will make every effort to release security patches in the case of a medium to high severity CVE directly impacting the library. The speed in which these patches reach a release is up to the discretion of the maintainers. A low severity CVE may be a lower priority than a high severity one.
+
+### Communication
+Cobra maintainers will use GitHub issues and the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) as the primary means of communication with the community. This is to foster open communication with all users and contributors.
+
+### Breaking Changes
+Breaking changes are generally allowed in the master branch, as this is the branch used to develop the next release of Cobra.
+
+There may be times, however, when master is closed for breaking changes. This is likely to happen as we near the release of a new version.
+
+Breaking changes are not allowed in release branches, as these represent minor versions that have already been released. These version have consumers who expect the APIs, behaviors, etc, to remain stable during the lifetime of the patch stream for the minor release.
+
+Examples of breaking changes include:
+- Removing or renaming exported constant, variable, type, or function.
+- Updating the version of critical libraries such as `spf13/pflag`, `spf13/viper` etc...
+ - Some version updates may be acceptable for picking up bug fixes, but maintainers must exercise caution when reviewing.
+
+There may, at times, need to be exceptions where breaking changes are allowed in release branches. These are at the discretion of the project's maintainers, and must be carefully considered before merging.
+
+### CI Testing
+Maintainers will ensure the Cobra test suite utilizes the current supported versions of Golang.

+Cobra is a library for creating powerful modern CLI applications.
+
+Visit Cobra.dev for extensive documentation
+
+
+Cobra is used in many Go projects such as [Kubernetes](https://kubernetes.io/),
+[Hugo](https://gohugo.io), and [GitHub CLI](https://github.com/cli/cli) to
+name a few. [This list](site/content/projects_using_cobra.md) contains a more extensive list of projects using Cobra.

+[Try Cobra in Warp today](https://www.warp.dev/cobra)
+
+
+
+
+# Overview
+
+Cobra is a library providing a simple interface to create powerful modern CLI
+interfaces similar to git & go tools.
+
+Cobra provides:
+* Easy subcommand-based CLIs: `app server`, `app fetch`, etc.
+* Fully POSIX-compliant flags (including short & long versions)
+* Nested subcommands
+* Global, local and cascading flags
+* Intelligent suggestions (`app srver`... did you mean `app server`?)
+* Automatic help generation for commands and flags
+* Grouping help for subcommands
+* Automatic help flag recognition of `-h`, `--help`, etc.
+* Automatically generated shell autocomplete for your application (bash, zsh, fish, powershell)
+* Automatically generated man pages for your application
+* Command aliases so you can change things without breaking them
+* The flexibility to define your own help, usage, etc.
+* Optional seamless integration with [viper](https://github.com/spf13/viper) for 12-factor apps
+
+# Concepts
+
+Cobra is built on a structure of commands, arguments & flags.
+
+**Commands** represent actions, **Args** are things and **Flags** are modifiers for those actions.
+
+The best applications read like sentences when used, and as a result, users
+intuitively know how to interact with them.
+
+The pattern to follow is
+`APPNAME VERB NOUN --ADJECTIVE`
+ or
+`APPNAME COMMAND ARG --FLAG`.
+
+A few good real world examples may better illustrate this point.
+
+In the following example, 'server' is a command, and 'port' is a flag:
+
+ hugo server --port=1313
+
+In this command we are telling Git to clone the url bare.
+
+ git clone URL --bare
+
+## Commands
+
+Command is the central point of the application. Each interaction that
+the application supports will be contained in a Command. A command can
+have children commands and optionally run an action.
+
+In the example above, 'server' is the command.
+
+[More about cobra.Command](https://pkg.go.dev/github.com/spf13/cobra#Command)
+
+## Flags
+
+A flag is a way to modify the behavior of a command. Cobra supports
+fully POSIX-compliant flags as well as the Go [flag package](https://golang.org/pkg/flag/).
+A Cobra command can define flags that persist through to children commands
+and flags that are only available to that command.
+
+In the example above, 'port' is the flag.
+
+Flag functionality is provided by the [pflag
+library](https://github.com/spf13/pflag), a fork of the flag standard library
+which maintains the same interface while adding POSIX compliance.
+
+# Installing
+Using Cobra is easy. First, use `go get` to install the latest version
+of the library.
+
+```
+go get -u github.com/spf13/cobra@latest
+```
+
+Next, include Cobra in your application:
+
+```go
+import "github.com/spf13/cobra"
+```
+
+# Usage
+`cobra-cli` is a command line program to generate cobra applications and command files.
+It will bootstrap your application scaffolding to rapidly
+develop a Cobra-based application. It is the easiest way to incorporate Cobra into your application.
+
+It can be installed by running:
+
+```
+go install github.com/spf13/cobra-cli@latest
+```
+
+For complete details on using the Cobra-CLI generator, please read [The Cobra Generator README](https://github.com/spf13/cobra-cli/blob/main/README.md)
+
+For complete details on using the Cobra library, please read [The Cobra User Guide](site/content/user_guide.md).

+# Security Policy
+
+## Reporting a Vulnerability
+
+The `cobra` maintainers take security issues seriously and
+we appreciate your efforts to _**responsibly**_ disclose your findings.
+We will make every effort to swiftly respond and address concerns.
+
+To report a security vulnerability:
+
+1. **DO NOT** create a public GitHub issue for the vulnerability!
+2. **DO NOT** create a public GitHub Pull Request with a fix for the vulnerability!
+3. Send an email to `cobra-security@googlegroups.com`.
+4. Include the following details in your report:
+ - Description of the vulnerability
+ - Steps to reproduce
+ - Potential impact of the vulnerability (to your downstream project, to the Go ecosystem, etc.)
+ - Any potential mitigations you've already identified
+5. Allow up to 7 days for an initial response.
+ You should receive an acknowledgment of your report and an estimated timeline for a fix.
+6. (Optional) If you have a fix and would like to contribute your patch, please work
+ directly with the maintainers via `cobra-security@googlegroups.com` to
+ coordinate pushing the patch to GitHub, cutting a new release, and disclosing the change.
+
+## Response Process
+
+When a security vulnerability report is received, the `cobra` maintainers will:
+
+1. Confirm receipt of the vulnerability report within 7 days.
+2. Assess the report to determine if it constitutes a security vulnerability.
+3. If confirmed, assign the vulnerability a severity level and create a timeline for addressing it.
+4. Develop and test a fix.
+5. Patch the vulnerability and make a new GitHub release: the maintainers will coordinate disclosure with the reporter.
+6. Create a new GitHub Security Advisory to inform the broader Go ecosystem
+
+## Disclosure Policy
+
+The `cobra` maintainers follow a coordinated disclosure process:
+
+1. Security vulnerabilities will be addressed as quickly as possible.
+2. A CVE (Common Vulnerabilities and Exposures) identifier will be requested for significant vulnerabilities
+ that are within `cobra` itself.
+3. Once a fix is ready, the maintainers will:
+ - Release a new version containing the fix.
+ - Update the security advisory with details about the vulnerability.
+ - Credit the reporter (unless they wish to remain anonymous).
+ - Credit the fixer (unless they wish to remain anonymous, this may be the same as the reporter).
+ - Announce the vulnerability through appropriate channels
+ (GitHub Security Advisory, mailing lists, GitHub Releases, etc.)
+
+## Supported Versions
+
+Security fixes will typically only be released for the most recent major release.
+
+## Upstream Security Issues
+
+`cobra` generally will not accept vulnerability reports that originate in upstream
+dependencies. I.e., if there is a problem in Go code that `cobra` depends on,
+it is best to engage that project's maintainers and owners.
+
+This security policy primarily pertains only to `cobra` itself but if you believe you've
+identified a problem that originates in an upstream dependency and is being widely
+distributed by `cobra`, please follow the disclosure procedure above: the `cobra`
+maintainers will work with you to determine the severity and ecosystem impact.
+
+## Security Updates and CVEs
+
+Information about known security vulnerabilities and CVEs affecting `cobra` will
+be published as GitHub Security Advisories at
+https://github.com/spf13/cobra/security/advisories.
+
+All users are encouraged to watch the repository and upgrade promptly when
+security releases are published.
+
+## `cobra` Security Best Practices for Users
+
+When using `cobra` in your CLIs, the `cobra` maintainers recommend the following:
+
+1. Always use the latest version of `cobra`.
+2. [Use Go modules](https://go.dev/blog/using-go-modules) for dependency management.
+3. Always use the latest possible version of Go.
+
+## Security Best Practices for Contributors
+
+When contributing to `cobra`:
+
+1. Be mindful of security implications when adding new features or modifying existing ones.
+2. Be aware of `cobra`'s extremely large reach: it is used in nearly every Go CLI
+ (like Kubernetes, Docker, Prometheus, etc. etc.)
+3. Write tests that explicitly cover edge cases and potential issues.
+4. If you discover a security issue while working on `cobra`, please report it
+ following the process above rather than opening a public pull request or issue that
+ addresses the vulnerability.
+5. Take personal sec-ops seriously and secure your GitHub account: use [two-factor authentication](https://docs.github.com/en/authentication/securing-your-account-with-two-factor-authentication-2fa),
+ [sign your commits with a GPG or SSH key](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification),
+ etc.
+
+## Acknowledgments
+
+The `cobra` maintainers would like to thank all security researchers and
+community members who help keep cobra, its users, and the entire Go ecosystem secure through responsible disclosures!!
+
+---
+
+*This security policy is inspired by the [Open Web Application Security Project (OWASP)](https://owasp.org/) guidelines and security best practices.*

+
+## 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 helper functions available to get the value stored in a Flag if you have a FlagSet but find
+it difficult to keep up with all of the 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()
+```

+
+
+## 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()
+}
+```
+
+### Using pflag with go test
+`pflag` does not parse the shorthand versions of go test's built-in flags (i.e., those starting with `-test.`).
+For more context, see issues [#63](https://github.com/spf13/pflag/issues/63) and [#238](https://github.com/spf13/pflag/issues/238) for more details.
+
+For example, if you use pflag in your `TestMain` function and call `pflag.Parse()` after defining your custom flags, running a test like this:
+```bash
+go test /your/tests -run ^YourTest -v --your-test-pflags
+```
+will result in the `-v` flag being ignored. This happens because of the way pflag handles flag parsing, skipping over go test's built-in shorthand flags.
+To work around this, you can use the `ParseSkippedFlags` function, which ensures that go test's flags are parsed separately using the standard flag package.
+
+**Example**: You want to parse go test flags that are otherwise ignore by `pflag.Parse()`
+```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.ParseSkippedFlags(os.Args[1:], goflag.CommandLine)
+ flag.Parse()
+}
+```
+
+## More info
+
+You can see the full reference documentation of the pflag package
+[at godoc.org][3], or through go's standard documentation system by
+running `godoc -http=:6060` and browsing to
+[http://localhost:6060/pkg/github.com/spf13/pflag][2] after
+installation.

+Package 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. See
+http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
+
+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.
+
+ 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.
+
+ var ip = flag.Int("flagname", 1234, "help message for flagname")
+
+If you like, you can bind the flag to a variable using the Var() functions.
+
+ 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
+
+ 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
+
+ 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.
+
+ fmt.Println("ip has value ", *ip)
+ fmt.Println("flagvar has value ", flagvar)
+
+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.
+
+ 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.
+
+Command line flag syntax:
+
+ --flag // boolean flags only
+ --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.
+
+ // boolean flags
+ -f
+ -abc
+ // non-boolean flags
+ -n 1234
+ -Ifile
+ // mixed
+ -abcs "hello"
+ -abcn1234
+
+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.
+
+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.

+# YAML support for the Go language
+
+Introduction
+------------
+
+The yaml package enables Go programs to comfortably encode and decode YAML
+values. It was developed within [Canonical](https://www.canonical.com) as
+part of the [juju](https://juju.ubuntu.com) project, and is based on a
+pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
+C library to parse and generate YAML data quickly and reliably.
+
+Compatibility
+-------------
+
+The yaml package supports most of YAML 1.1 and 1.2, including support for
+anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
+implemented, and base-60 floats from YAML 1.1 are purposefully not
+supported since they're a poor design and are gone in YAML 1.2.
+
+Installation and usage
+----------------------
+
+The import path for the package is *gopkg.in/yaml.v2*.
+
+To install it, run:
+
+ go get gopkg.in/yaml.v2
+
+API documentation
+-----------------
+
+If opened in a browser, the import path itself leads to the API documentation:
+
+ * [https://gopkg.in/yaml.v2](https://gopkg.in/yaml.v2)
+
+API stability
+-------------
+
+The package API for yaml v2 will remain stable as described in [gopkg.in](https://gopkg.in).
+
+
+License
+-------
+
+The yaml package is licensed under the Apache License 2.0. Please see the LICENSE file for details.
+
+
+Example
+-------
+
+```Go
+package main
+
+import (
+ "fmt"
+ "log"
+
+ "gopkg.in/yaml.v2"
+)
+
+var data = `
+a: Easy!
+b:
+ c: 2
+ d: [3, 4]
+`
+
+// Note: struct fields must be public in order for unmarshal to
+// correctly populate the data.
+type T struct {
+ A string
+ B struct {
+ RenamedC int `yaml:"c"`
+ D []int `yaml:",flow"`
+ }
+}
+
+func main() {
+ t := T{}
+
+ err := yaml.Unmarshal([]byte(data), &t)
+ if err != nil {
+ log.Fatalf("error: %v", err)
+ }
+ fmt.Printf("--- t:\n%v\n\n", t)
+
+ d, err := yaml.Marshal(&t)
+ if err != nil {
+ log.Fatalf("error: %v", err)
+ }
+ fmt.Printf("--- t dump:\n%s\n\n", string(d))
+
+ m := make(map[interface{}]interface{})
+
+ err = yaml.Unmarshal([]byte(data), &m)
+ if err != nil {
+ log.Fatalf("error: %v", err)
+ }
+ fmt.Printf("--- m:\n%v\n\n", m)
+
+ d, err = yaml.Marshal(&m)
+ if err != nil {
+ log.Fatalf("error: %v", err)
+ }
+ fmt.Printf("--- m dump:\n%s\n\n", string(d))
+}
+```
+
+This example will generate the following output:
+
+```
+--- t:
+{Easy! {2 [3 4]}}
+
+--- t dump:
+a: Easy!
+b:
+ c: 2
+ d: [3, 4]
+
+
+--- m:
+map[a:Easy! b:map[c:2 d:[3 4]]]
+
+--- m dump:
+a: Easy!
+b:
+ c: 2
+ d:
+ - 3
+ - 4
+```

+
+// Introduction
+// ************
+//
+// The following notes assume that you are familiar with the YAML specification
+// (http://yaml.org/spec/1.2/spec.html). We mostly follow it, although in
+// some cases we are less restrictive that it requires.
+//
+// The process of transforming a YAML stream into a sequence of events is
+// divided on two steps: Scanning and Parsing.
+//
+// The Scanner transforms the input stream into a sequence of tokens, while the
+// parser transform the sequence of tokens produced by the Scanner into a
+// sequence of parsing events.
+//
+// The Scanner is rather clever and complicated. The Parser, on the contrary,
+// is a straightforward implementation of a recursive-descendant parser (or,
+// LL(1) parser, as it is usually called).
+//
+// Actually there are two issues of Scanning that might be called "clever", the
+// rest is quite straightforward. The issues are "block collection start" and
+// "simple keys". Both issues are explained below in details.
+//
+// Here the Scanning step is explained and implemented. We start with the list
+// of all the tokens produced by the Scanner together with short descriptions.
+//
+// Now, tokens:
+//
+// STREAM-START(encoding) # The stream start.
+// STREAM-END # The stream end.
+// VERSION-DIRECTIVE(major,minor) # The '%YAML' directive.
+// TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive.
+// DOCUMENT-START # '---'
+// DOCUMENT-END # '...'
+// BLOCK-SEQUENCE-START # Indentation increase denoting a block
+// BLOCK-MAPPING-START # sequence or a block mapping.
+// BLOCK-END # Indentation decrease.
+// FLOW-SEQUENCE-START # '['
+// FLOW-SEQUENCE-END # ']'
+// BLOCK-SEQUENCE-START # '{'
+// BLOCK-SEQUENCE-END # '}'
+// BLOCK-ENTRY # '-'
+// FLOW-ENTRY # ','
+// KEY # '?' or nothing (simple keys).
+// VALUE # ':'
+// ALIAS(anchor) # '*anchor'
+// ANCHOR(anchor) # '&anchor'
+// TAG(handle,suffix) # '!handle!suffix'
+// SCALAR(value,style) # A scalar.
+//
+// The following two tokens are "virtual" tokens denoting the beginning and the
+// end of the stream:
+//
+// STREAM-START(encoding)
+// STREAM-END
+//
+// We pass the information about the input stream encoding with the
+// STREAM-START token.
+//
+// The next two tokens are responsible for tags:
+//
+// VERSION-DIRECTIVE(major,minor)
+// TAG-DIRECTIVE(handle,prefix)
+//
+// Example:
+//
+// %YAML 1.1
+// %TAG ! !foo
+// %TAG !yaml! tag:yaml.org,2002:
+// ---
+//
+// The correspoding sequence of tokens:
+//
+// STREAM-START(utf-8)
+// VERSION-DIRECTIVE(1,1)
+// TAG-DIRECTIVE("!","!foo")
+// TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
+// DOCUMENT-START
+// STREAM-END
+//
+// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
+// line.
+//
+// The document start and end indicators are represented by:
+//
+// DOCUMENT-START
+// DOCUMENT-END
+//
+// Note that if a YAML stream contains an implicit document (without '---'
+// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
+// produced.
+//
+// In the following examples, we present whole documents together with the
+// produced tokens.
+//
+// 1. An implicit document:
+//
+// 'a scalar'
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// SCALAR("a scalar",single-quoted)
+// STREAM-END
+//
+// 2. An explicit document:
+//
+// ---
+// 'a scalar'
+// ...
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// DOCUMENT-START
+// SCALAR("a scalar",single-quoted)
+// DOCUMENT-END
+// STREAM-END
+//
+// 3. Several documents in a stream:
+//
+// 'a scalar'
+// ---
+// 'another scalar'
+// ---
+// 'yet another scalar'
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// SCALAR("a scalar",single-quoted)
+// DOCUMENT-START
+// SCALAR("another scalar",single-quoted)
+// DOCUMENT-START
+// SCALAR("yet another scalar",single-quoted)
+// STREAM-END
+//
+// We have already introduced the SCALAR token above. The following tokens are
+// used to describe aliases, anchors, tag, and scalars:
+//
+// ALIAS(anchor)
+// ANCHOR(anchor)
+// TAG(handle,suffix)
+// SCALAR(value,style)
+//
+// The following series of examples illustrate the usage of these tokens:
+//
+// 1. A recursive sequence:
+//
+// &A [ *A ]
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// ANCHOR("A")
+// FLOW-SEQUENCE-START
+// ALIAS("A")
+// FLOW-SEQUENCE-END
+// STREAM-END
+//
+// 2. A tagged scalar:
+//
+// !!float "3.14" # A good approximation.
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// TAG("!!","float")
+// SCALAR("3.14",double-quoted)
+// STREAM-END
+//
+// 3. Various scalar styles:
+//
+// --- # Implicit empty plain scalars do not produce tokens.
+// --- a plain scalar
+// --- 'a single-quoted scalar'
+// --- "a double-quoted scalar"
+// --- |-
+// a literal scalar
+// --- >-
+// a folded
+// scalar
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// DOCUMENT-START
+// DOCUMENT-START
+// SCALAR("a plain scalar",plain)
+// DOCUMENT-START
+// SCALAR("a single-quoted scalar",single-quoted)
+// DOCUMENT-START
+// SCALAR("a double-quoted scalar",double-quoted)
+// DOCUMENT-START
+// SCALAR("a literal scalar",literal)
+// DOCUMENT-START
+// SCALAR("a folded scalar",folded)
+// STREAM-END
+//
+// Now it's time to review collection-related tokens. We will start with
+// flow collections:
+//
+// FLOW-SEQUENCE-START
+// FLOW-SEQUENCE-END
+// FLOW-MAPPING-START
+// FLOW-MAPPING-END
+// FLOW-ENTRY
+// KEY
+// VALUE
+//
+// The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
+// FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
+// correspondingly. FLOW-ENTRY represent the ',' indicator. Finally the
+// indicators '?' and ':', which are used for denoting mapping keys and values,
+// are represented by the KEY and VALUE tokens.
+//
+// The following examples show flow collections:
+//
+// 1. A flow sequence:
+//
+// [item 1, item 2, item 3]
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// FLOW-SEQUENCE-START
+// SCALAR("item 1",plain)
+// FLOW-ENTRY
+// SCALAR("item 2",plain)
+// FLOW-ENTRY
+// SCALAR("item 3",plain)
+// FLOW-SEQUENCE-END
+// STREAM-END
+//
+// 2. A flow mapping:
+//
+// {
+// a simple key: a value, # Note that the KEY token is produced.
+// ? a complex key: another value,
+// }
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// FLOW-MAPPING-START
+// KEY
+// SCALAR("a simple key",plain)
+// VALUE
+// SCALAR("a value",plain)
+// FLOW-ENTRY
+// KEY
+// SCALAR("a complex key",plain)
+// VALUE
+// SCALAR("another value",plain)
+// FLOW-ENTRY
+// FLOW-MAPPING-END
+// STREAM-END
+//
+// A simple key is a key which is not denoted by the '?' indicator. Note that
+// the Scanner still produce the KEY token whenever it encounters a simple key.
+//
+// For scanning block collections, the following tokens are used (note that we
+// repeat KEY and VALUE here):
+//
+// BLOCK-SEQUENCE-START
+// BLOCK-MAPPING-START
+// BLOCK-END
+// BLOCK-ENTRY
+// KEY
+// VALUE
+//
+// The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
+// increase that precedes a block collection (cf. the INDENT token in Python).
+// The token BLOCK-END denote indentation decrease that ends a block collection
+// (cf. the DEDENT token in Python). However YAML has some syntax pecularities
+// that makes detections of these tokens more complex.
+//
+// The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
