The goal is to enable developers to write fast and distributable command line applications in an expressive way. + +You can view the API docs here: +http://godoc.org/github.com/codegangsta/cli + +## Overview +Command line apps are usually so tiny that there is absolutely no reason why your code should *not* be self-documenting. Things like generating help text and parsing command flags/options should not hinder productivity when writing a command line app. + +**This is where cli.go comes into play.** cli.go makes command line programming fun, organized, and expressive! + +## Installation +Make sure you have a working Go environment (go 1.1 is *required*). [See the install instructions](http://golang.org/doc/install.html). + +To install `cli.go`, simply run: +``` +$ go get github.com/codegangsta/cli +``` + +Make sure your `PATH` includes to the `$GOPATH/bin` directory so your commands can be easily used: +``` +export PATH=$PATH:$GOPATH/bin +``` + +## Getting Started +One of the philosophies behind cli.go is that an API should be playful and full of discovery. So a cli.go app can be as little as one line of code in `main()`. + +``` go +package main + +import ( + "os" + "github.com/codegangsta/cli" +) + +func main() { + cli.NewApp().Run(os.Args) +} +``` + +This app will run and show help text, but is not very useful. Let's give an action to execute and some help documentation: + +``` go +package main + +import ( + "os" + "github.com/codegangsta/cli" +) + +func main() { + app := cli.NewApp() + app.Name = "boom" + app.Usage = "make an explosive entrance" + app.Action = func(c *cli.Context) { + println("boom! I say!") + } + + app.Run(os.Args) +} +``` + +Running this already gives you a ton of functionality, plus support for things like subcommands and flags, which are covered below. + +## Example + +Being a programmer can be a lonely job. Thankfully by the power of automation that is not the case! Let's create a greeter app to fend off our demons of loneliness! + +Start by creating a directory named `greet`, and within it, add a file, `greet.go` with the following code in it: + +``` go +package main + +import ( + "os" + "github.com/codegangsta/cli" +) + +func main() { + app := cli.NewApp() + app.Name = "greet" + app.Usage = "fight the loneliness!" + app.Action = func(c *cli.Context) { + println("Hello friend!") + } + + app.Run(os.Args) +} +``` + +Install our command to the `$GOPATH/bin` directory: + +``` +$ go install +``` + +Finally run our new command: + +``` +$ greet +Hello friend! +``` + +cli.go also generates some bitchass help text: +``` +$ greet help +NAME: + greet - fight the loneliness! + +USAGE: + greet [global options] command [command options] [arguments...] + +VERSION: + 0.0.0 + +COMMANDS: + help, h Shows a list of commands or help for one command + +GLOBAL OPTIONS + --version Shows version information +``` + +### Arguments +You can lookup arguments by calling the `Args` function on `cli.Context`. + +``` go +... +app.Action = func(c *cli.Context) { + println("Hello", c.Args()[0]) +} +... +``` + +### Flags +Setting and querying flags is simple. +``` go +... +app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang", + Value: "english", + Usage: "language for the greeting", + }, +} +app.Action = func(c *cli.Context) { + name := "someone" + if len(c.Args()) > 0 { + name = c.Args()[0] + } + if c.String("lang") == "spanish" { + println("Hola", name) + } else { + println("Hello", name) + } +} +... +``` + +#### Alternate Names + +You can set alternate (or short) names for flags by providing a comma-delimited list for the `Name`. e.g. + +``` go +app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "language for the greeting", + }, +} +``` + +That flag can then be set with `--lang spanish` or `-l spanish`. Note that giving two different forms of the same flag in the same command invocation is an error. + +#### Values from the Environment + +You can also have the default value set from the environment via `EnvVar`. e.g. + +``` go +app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "language for the greeting", + EnvVar: "APP_LANG", + }, +} +``` + +The `EnvVar` may also be given as a comma-delimited "cascade", where the first environment variable that resolves is used as the default. + +``` go +app.Flags = []cli.Flag { + cli.StringFlag{ + Name: "lang, l", + Value: "english", + Usage: "language for the greeting", + EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG", + }, +} +``` + +### Subcommands + +Subcommands can be defined for a more git-like command line app. +```go +... +app.Commands = []cli.Command{ + { + Name: "add", + ShortName: "a", + Usage: "add a task to the list", + Action: func(c *cli.Context) { + println("added task: ", c.Args().First()) + }, + }, + { + Name: "complete", + ShortName: "c", + Usage: "complete a task on the list", + Action: func(c *cli.Context) { + println("completed task: ", c.Args().First()) + }, + }, + { + Name: "template", + ShortName: "r", + Usage: "options for task templates", + Subcommands: []cli.Command{ + { + Name: "add", + Usage: "add a new template", + Action: func(c *cli.Context) { + println("new task template: ", c.Args().First()) + }, + }, + { + Name: "remove", + Usage: "remove an existing template", + Action: func(c *cli.Context) { + println("removed task template: ", c.Args().First()) + }, + }, + }, + }, +} +... +``` + +### Bash Completion + +You can enable completion commands by setting the `EnableBashCompletion` +flag on the `App` object. By default, this setting will only auto-complete to +show an app's subcommands, but you can write your own completion methods for +the App or its subcommands. +```go +... +var tasks = []string{"cook", "clean", "laundry", "eat", "sleep", "code"} +app := cli.NewApp() +app.EnableBashCompletion = true +app.Commands = []cli.Command{ + { + Name: "complete", + ShortName: "c", + Usage: "complete a task on the list", + Action: func(c *cli.Context) { + println("completed task: ", c.Args().First()) + }, + BashComplete: func(c *cli.Context) { + // This will complete if no args are passed + if len(c.Args()) > 0 { + return + } + for _, t := range tasks { + fmt.Println(t) + } + }, + } +} +... +``` + +#### To Enable + +Source the `autocomplete/bash_autocomplete` file in your `.bashrc` file while +setting the `PROG` variable to the name of your program: + +`PROG=myprogram source /.../cli/autocomplete/bash_autocomplete` + + +## Contribution Guidelines +Feel free to put up a pull request to fix a bug or maybe add a feature. I will give it a code review and make sure that it does not break backwards compatibility. If I or any other collaborators agree that it is in line with the vision of the project, we will work with you to get the code into a mergeable state and merge it into the master branch. + +If you have contributed something significant to the project, I will most likely add you as a collaborator. As a collaborator you are given the ability to merge others pull requests. It is very important that new code does not break existing code, so be careful about what code you do choose to merge. If you have any questions feel free to link @codegangsta to the issue in question and we can review it together. + +If you feel like you have contributed to the project but have not yet been added as a collaborator, I probably forgot to add you.

The +# package is considered found if all variables <var1>... listed contain +# valid results, e.g. valid filepaths. +# +# There are two modes of this function.

Other names for the result-variable are not +# allowed. So for a Find-module named FindFooBar.cmake, the two +# possible names are FooBar_FOUND and FOOBAR_FOUND. It is recommended +# to use the original case version. If the FOUND_VAR option is not +# used, the default is <UPPERCASED_NAME>_FOUND. +# +# As in the simple mode, if <var1> through <varN> are all valid, +# <packagename>_FOUND will be set to TRUE. After REQUIRED_VARS the +# variables which are required for this package are listed. Following +# VERSION_VAR the name of the variable can be specified which holds the +# version of the package which has been found. If this is done, this +# version will be checked against the (potentially) specified required +# version used in the find_package() call. The EXACT keyword is also +# handled. The default messages include information about the required +# version and the version which has been actually found, both if the +# version is ok or not. If the package supports components, use the +# HANDLE_COMPONENTS option to enable handling them. In this case, +# find_package_handle_standard_args() will report which components have +# been found and which are missing, and the <packagename>_FOUND variable +# will be set to FALSE if any of the required components (i.e. not the +# ones listed after OPTIONAL_COMPONENTS) are missing. Use the option +# CONFIG_MODE if your FindXXX.cmake module is a wrapper for a +# find_package(... NO_MODULE) call. In this case VERSION_VAR will be +# set to <NAME>_VERSION and the macro will automatically check whether +# the Config module was found. Via FAIL_MESSAGE a custom failure +# message can be specified, if this is not used, the default message +# will be displayed. +# +# Example for mode 1: +# +# :: +# +# find_package_handle_standard_args(LibXml2 DEFAULT_MSG +# LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR) +# +# +# +# LibXml2 is considered to be found, if both LIBXML2_LIBRARY and +# LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to +# TRUE. If it is not found and REQUIRED was used, it fails with +# FATAL_ERROR, independent whether QUIET was used or not. If it is +# found, success will be reported, including the content of <var1>. On +# repeated Cmake runs, the same message won't be printed again. +# +# Example for mode 2: +# +# :: +# +# find_package_handle_standard_args(LibXslt +# FOUND_VAR LibXslt_FOUND +# REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS +# VERSION_VAR LibXslt_VERSION_STRING) +# +# In this case, LibXslt is considered to be found if the variable(s) +# listed after REQUIRED_VAR are all valid, i.e. LibXslt_LIBRARIES and +# LibXslt_INCLUDE_DIRS in this case. The result will then be stored in +# LibXslt_FOUND . Also the version of LibXslt will be checked by using +# the version contained in LibXslt_VERSION_STRING. Since no +# FAIL_MESSAGE is given, the default messages will be printed. +# +# Another example for mode 2: +# +# :: +# +# find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4) +# find_package_handle_standard_args(Automoc4 CONFIG_MODE) +# +# In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4 +# NO_MODULE) and adds an additional search directory for automoc4.

Issue - * multiple calls if longer format strings are required. - * - * It requires minimal setup, and is *NOT* optimised for performance. - * For example, writes are not coalesced - this is because there is an - * assumption that people will not want to printf from every single one - * of thousands of threads, but only from individual threads at a time. - * - * Using this is simple - it requires one host-side call to initialise - * everything, and then kernels can call cuPrintf at will.
