Things like generating help text and -parsing command flags/options should not hinder productivity when writing a -command line app. - -**This is where cli comes into play.** cli makes command line programming fun, -organized, and expressive! - -## Installation - -Make sure you have a working Go environment. Go version 1.2+ is supported. [See -the install instructions for Go](http://golang.org/doc/install.html). - -To install cli, simply run: -``` -$ go get github.com/urfave/cli -``` - -Make sure your `PATH` includes the `$GOPATH/bin` directory so your commands can -be easily used: -``` -export PATH=$PATH:$GOPATH/bin -``` - -### Supported platforms - -cli is tested against multiple versions of Go on Linux, and against the latest -released version of Go on OS X and Windows. For full details, see -[`./.travis.yml`](./.travis.yml) and [`./appveyor.yml`](./appveyor.yml). - -### Using the `v2` branch - -**Warning**: The `v2` branch is currently unreleased and considered unstable. - -There is currently a long-lived branch named `v2` that is intended to land as -the new `master` branch once development there has settled down. The current -`master` branch (mirrored as `v1`) is being manually merged into `v2` on -an irregular human-based schedule, but generally if one wants to "upgrade" to -`v2` *now* and accept the volatility (read: "awesomeness") that comes along with -that, please use whatever version pinning of your preference, such as via -`gopkg.in`: - -``` -$ go get gopkg.in/urfave/cli.v2 -``` - -``` go -... -import ( - "gopkg.in/urfave/cli.v2" // imports as package "cli" -) -... -``` - -### Pinning to the `v1` releases - -Similarly to the section above describing use of the `v2` branch, if one wants -to avoid any unexpected compatibility pains once `v2` becomes `master`, then -pinning to `v1` is an acceptable option, e.g.: - -``` -$ go get gopkg.in/urfave/cli.v1 -``` - -``` go -... -import ( - "gopkg.in/urfave/cli.v1" // imports as package "cli" -) -... -``` - -This will pull the latest tagged `v1` release (e.g. `v1.18.1` at the time of writing). - -## Getting Started - -One of the philosophies behind cli is that an API should be playful and full of -discovery. So a cli app can be as little as one line of code in `main()`. - - -``` go -package main - -import ( - "os" - - "github.com/urfave/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 ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - app.Name = "boom" - app.Usage = "make an explosive entrance" - app.Action = func(c *cli.Context) error { - fmt.Println("boom! I say!") - return nil - } - - 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. - -## Examples - -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 ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - app.Name = "greet" - app.Usage = "fight the loneliness!" - app.Action = func(c *cli.Context) error { - fmt.Println("Hello friend!") - return nil - } - - app.Run(os.Args) -} -``` - -Install our command to the `$GOPATH/bin` directory: - -``` -$ go install -``` - -Finally run our new command: - -``` -$ greet -Hello friend! -``` - -cli also generates neat 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`, e.g.: - - -``` go -package main - -import ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Action = func(c *cli.Context) error { - fmt.Printf("Hello %q", c.Args().Get(0)) - return nil - } - - app.Run(os.Args) -} -``` - -### Flags - -Setting and querying flags is simple. - - -``` go -package main - -import ( - "fmt" - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang", - Value: "english", - Usage: "language for the greeting", - }, - } - - app.Action = func(c *cli.Context) error { - name := "Nefertiti" - if c.NArg() > 0 { - name = c.Args().Get(0) - } - if c.String("lang") == "spanish" { - fmt.Println("Hola", name) - } else { - fmt.Println("Hello", name) - } - return nil - } - - app.Run(os.Args) -} -``` - -You can also set a destination variable for a flag, to which the content will be -scanned. - - -``` go -package main - -import ( - "os" - "fmt" - - "github.com/urfave/cli" -) - -func main() { - var language string - - app := cli.NewApp() - - app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang", - Value: "english", - Usage: "language for the greeting", - Destination: &language, - }, - } - - app.Action = func(c *cli.Context) error { - name := "someone" - if c.NArg() > 0 { - name = c.Args()[0] - } - if language == "spanish" { - fmt.Println("Hola", name) - } else { - fmt.Println("Hello", name) - } - return nil - } - - app.Run(os.Args) -} -``` - -See full list of flags at http://godoc.org/github.com/urfave/cli - -#### Placeholder Values - -Sometimes it's useful to specify a flag's value within the usage string itself. -Such placeholders are indicated with back quotes. - -For example this: - - -```go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Flags = []cli.Flag{ - cli.StringFlag{ - Name: "config, c", - Usage: "Load configuration from `FILE`", - }, - } - - app.Run(os.Args) -} -``` - -Will result in help output like: - -``` ---config FILE, -c FILE Load configuration from FILE -``` - -Note that only the first placeholder is used. Subsequent back-quoted words will -be left as-is. - -#### Alternate Names - -You can set alternate (or short) names for flags by providing a comma-delimited -list for the `Name`. e.g. - - -``` go -package main - -import ( - "os" - - "github.com/urfave/cli" -) - -func main() { - app := cli.NewApp() - - app.Flags = []cli.Flag { - cli.StringFlag{ - Name: "lang, l", - Value: "english", - Usage: "language for the greeting", - }, - } - - app.Run(os.Args) -} -``` - -That flag can then be set with `--lang spanish` or `-l spanish`.

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, we 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 feel like you have contributed to the project but have not yet been -added as a collaborator, we probably forgot to add you, please open an issue. diff --git a/vendor/github.com/urfave/cli/app.go b/vendor/github.com/urfave/cli/app.go deleted file mode 100644 index 95ffc0b..0000000 --- a/vendor/github.com/urfave/cli/app.go +++ /dev/null @@ -1,492 +0,0 @@ -package cli - -import ( - "fmt" - "io" - "io/ioutil" - "os" - "path/filepath" - "sort" - "time" -) - -var ( - changeLogURL = "https://github.com/urfave/cli/blob/master/CHANGELOG.md" - appActionDeprecationURL = fmt.Sprintf("%s#deprecated-cli-app-action-signature", changeLogURL) - runAndExitOnErrorDeprecationURL = fmt.Sprintf("%s#deprecated-cli-app-runandexitonerror", changeLogURL) - - contactSysadmin = "This is an error in the application.
