-## 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 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
-...

- "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()`.
-
-<!-- {
- "args": ["&#45;&#45;help"],
- "output": "A new cli application"
-} -->
-``` go
-package main
-
-import (
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- err := cli.NewApp().Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-This app will run and show help text, but is not very useful. Let's give an
-action to execute and some help documentation:
-
-<!-- {
- "output": "boom! I say!"
-} -->
-``` go
-package main
-
-import (
- "fmt"
- "log"
- "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
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-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:
-
-<!-- {
- "output": "Hello friend!"
-} -->
-``` go
-package main
-
-import (
- "fmt"
- "log"
- "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
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-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.:
-
-<!-- {
- "output": "Hello \""
-} -->
-``` go
-package main
-
-import (
- "fmt"
- "log"
- "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
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-### Flags
-
-Setting and querying flags is simple.
-
-<!-- {
- "output": "Hello Nefertiti"
-} -->
-``` go
-package main
-
-import (
- "fmt"
- "log"
- "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
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-You can also set a destination variable for a flag, to which the content will be
-scanned.
-
-<!-- {
- "output": "Hello someone"
-} -->
-``` go
-package main
-
-import (
- "log"
- "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
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-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:
-
-<!-- {
- "args": ["&#45;&#45;help"],
- "output": "&#45;&#45;config FILE, &#45;c FILE"
-} -->
-```go
-package main
-
-import (
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- app := cli.NewApp()
-
- app.Flags = []cli.Flag{
- cli.StringFlag{
- Name: "config, c",
- Usage: "Load configuration from `FILE`",
- },
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-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.
-
-<!-- {
- "args": ["&#45;&#45;help"],
- "output": "&#45;&#45;lang value, &#45;l value.*language for the greeting.*default: \"english\""
-} -->
-``` go
-package main
-
-import (
- "log"
- "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",
- },
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-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.
-
-#### Ordering
-
-Flags for the application and commands are shown in the order they are defined.
-However, it's possible to sort them from outside this library by using `FlagsByName`
-or `CommandsByName` with `sort`.
-
-For example this:
-
-<!-- {
- "args": ["&#45;&#45;help"],
- "output": "add a task to the list\n.*complete a task on the list\n.*\n\n.*\n.*Load configuration from FILE\n.*Language for the greeting.*"
-} -->
-``` go
-package main
-
-import (
- "log"
- "os"
- "sort"
-
- "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",
- },
- cli.StringFlag{
- Name: "config, c",
- Usage: "Load configuration from `FILE`",
- },
- }
-
- app.Commands = []cli.Command{
- {
- Name: "complete",
- Aliases: []string{"c"},
- Usage: "complete a task on the list",
- Action: func(c *cli.Context) error {
- return nil
- },
- },
- {
- Name: "add",
- Aliases: []string{"a"},
- Usage: "add a task to the list",
- Action: func(c *cli.Context) error {
- return nil
- },
- },
- }
-
- sort.Sort(cli.FlagsByName(app.Flags))
- sort.Sort(cli.CommandsByName(app.Commands))
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-Will result in help output like:
-
-```
---config FILE, -c FILE Load configuration from FILE
---lang value, -l value Language for the greeting (default: "english")
-```
-
-#### Values from the Environment
-
-You can also have the default value set from the environment via `EnvVar`. e.g.
-
-<!-- {
- "args": ["&#45;&#45;help"],
- "output": "language for the greeting.*APP_LANG"
-} -->
-``` go
-package main
-
-import (
- "log"
- "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",
- EnvVar: "APP_LANG",
- },
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-The `EnvVar` may also be given as a comma-delimited "cascade", where the first
-environment variable that resolves is used as the default.
-
-<!-- {
- "args": ["&#45;&#45;help"],
- "output": "language for the greeting.*LEGACY_COMPAT_LANG.*APP_LANG.*LANG"
-} -->
-``` go
-package main
-
-import (
- "log"
- "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",
- EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG",
- },
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-#### Values from files
-
-You can also have the default value set from file via `FilePath`. e.g.
-
-<!-- {
- "args": ["&#45;&#45;help"],
- "output": "password for the mysql database"
-} -->
-``` go
-package main
-
-import (
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- app := cli.NewApp()
-
- app.Flags = []cli.Flag {
- cli.StringFlag{
- Name: "password, p",
- Usage: "password for the mysql database",
- FilePath: "/etc/mysql/password",
- },
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-Note that default values set from file (e.g. `FilePath`) take precedence over
-default values set from the enviornment (e.g. `EnvVar`).
-
-#### Values from alternate input sources (YAML, TOML, and others)
-
-There is a separate package altsrc that adds support for getting flag values
-from other file input sources.
-
-Currently supported input source formats:
-* YAML
-* TOML
-
-In order to get values for a flag from an alternate input source the following
-code would be added to wrap an existing cli.Flag like below:
-
-``` go
- altsrc.NewIntFlag(cli.IntFlag{Name: "test"})
-```
-
-Initialization must also occur for these flags. Below is an example initializing
-getting data from a yaml file below.
-
-``` go
- command.Before = altsrc.InitInputSourceWithContext(command.Flags, NewYamlSourceFromFlagFunc("load"))
-```
-
-The code above will use the "load" string as a flag name to get the file name of
-a yaml file from the cli.Context. It will then use that file name to initialize
-the yaml input source for any flags that are defined on that command. As a note
-the "load" flag used would also have to be defined on the command flags in order
-for this code snipped to work.
-
-Currently only YAML and JSON files are supported but developers can add support
-for other input sources by implementing the altsrc.InputSourceContext for their
-given sources.
-
-Here is a more complete sample of a command using YAML support:
-
-<!-- {
- "args": ["test-cmd", "&#45;&#45;help"],
- "output": "&#45&#45;test value.*default: 0"
-} -->
-``` go
-package notmain
-
-import (
- "fmt"
- "log"
- "os"
-
- "github.com/urfave/cli"
- "github.com/urfave/cli/altsrc"
-)
-
-func main() {
- app := cli.NewApp()
-
- flags := []cli.Flag{
- altsrc.NewIntFlag(cli.IntFlag{Name: "test"}),
- cli.StringFlag{Name: "load"},
- }
-
- app.Action = func(c *cli.Context) error {
- fmt.Println("yaml ist rad")
- return nil
- }
-
- app.Before = altsrc.InitInputSourceWithContext(flags, altsrc.NewYamlSourceFromFlagFunc("load"))
- app.Flags = flags
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-#### Precedence
-
-The precedence for flag value sources is as follows (highest to lowest):
-
-0. Command line flag value from user
-0. Environment variable (if specified)
-0. Configuration file (if specified)
-0. Default defined on the flag
-
-### Subcommands
-
-Subcommands can be defined for a more git-like command line app.
-
-<!-- {
- "args": ["template", "add"],
- "output": "new task template: .+"
-} -->
-```go
-package main
-
-import (
- "fmt"
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- app := cli.NewApp()
-
- app.Commands = []cli.Command{
- {
- Name: "add",
- Aliases: []string{"a"},
- Usage: "add a task to the list",
- Action: func(c *cli.Context) error {
- fmt.Println("added task: ", c.Args().First())
- return nil
- },
- },
- {
- Name: "complete",
- Aliases: []string{"c"},
- Usage: "complete a task on the list",
- Action: func(c *cli.Context) error {
- fmt.Println("completed task: ", c.Args().First())
- return nil
- },
- },
- {
- Name: "template",
- Aliases: []string{"t"},
- Usage: "options for task templates",
- Subcommands: []cli.Command{
- {
- Name: "add",
- Usage: "add a new template",
- Action: func(c *cli.Context) error {
- fmt.Println("new task template: ", c.Args().First())
- return nil
- },
- },
- {
- Name: "remove",
- Usage: "remove an existing template",
- Action: func(c *cli.Context) error {
- fmt.Println("removed task template: ", c.Args().First())
- return nil
- },
- },
- },
- },
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-### Subcommands categories
-
-For additional organization in apps that have many subcommands, you can
-associate a category for each command to group them together in the help
-output.
-
-E.g.
-
-```go
-package main
-
-import (
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- app := cli.NewApp()
-
- app.Commands = []cli.Command{
- {
- Name: "noop",
- },
- {
- Name: "add",
- Category: "Template actions",
- },
- {
- Name: "remove",
- Category: "Template actions",
- },
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-Will include:
-
-```
-COMMANDS:
- noop
-
- Template actions:
- add
- remove
-```
-
-### Exit code
-
-Calling `App.Run` will not automatically call `os.Exit`, which means that by
-default the exit code will "fall through" to being `0`. An explicit exit code
-may be set by returning a non-nil error that fulfills `cli.ExitCoder`, *or* a
-`cli.MultiError` that includes an error that fulfills `cli.ExitCoder`, e.g.:
-
-``` go
-package main
-
-import (
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- app := cli.NewApp()
- app.Flags = []cli.Flag{
- cli.BoolTFlag{
- Name: "ginger-crouton",
- Usage: "is it in the soup?",
- },
- }
- app.Action = func(ctx *cli.Context) error {
- if !ctx.Bool("ginger-crouton") {
- return cli.NewExitError("it is not in the soup", 86)
- }
- return nil
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-### 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.
-
-<!-- {
- "args": ["complete", "&#45;&#45;generate&#45;bash&#45;completion"],
- "output": "laundry"
-} -->
-``` go
-package main
-
-import (
- "fmt"
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- tasks := []string{"cook", "clean", "laundry", "eat", "sleep", "code"}
-
- app := cli.NewApp()
- app.EnableBashCompletion = true
- app.Commands = []cli.Command{
- {
- Name: "complete",
- Aliases: []string{"c"},
- Usage: "complete a task on the list",
- Action: func(c *cli.Context) error {
- fmt.Println("completed task: ", c.Args().First())
- return nil
- },
- BashComplete: func(c *cli.Context) {
- // This will complete if no args are passed
- if c.NArg() > 0 {
- return
- }
- for _, t := range tasks {
- fmt.Println(t)
- }
- },
- },
- }
-
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-#### Enabling
-
-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`
-
-#### Distribution
-
-Copy `autocomplete/bash_autocomplete` into `/etc/bash_completion.d/` and rename
-it to the name of the program you wish to add autocomplete support for (or
-automatically install it there if you are distributing a package). Don't forget
-to source the file to make it active in the current shell.
-
-```
-sudo cp src/bash_autocomplete /etc/bash_completion.d/<myprogram>
-source /etc/bash_completion.d/<myprogram>
-```
-
-Alternatively, you can just document that users should source the generic
-`autocomplete/bash_autocomplete` in their bash configuration with `$PROG` set
-to the name of their program (as above).
-
-#### Customization
-
-The default bash completion flag (`--generate-bash-completion`) is defined as
-`cli.BashCompletionFlag`, and may be redefined if desired, e.g.:
-
-<!-- {
- "args": ["&#45;&#45;compgen"],
- "output": "wat\nhelp\nh"
-} -->
-``` go
-package main
-
-import (
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- cli.BashCompletionFlag = cli.BoolFlag{
- Name: "compgen",
- Hidden: true,
- }
-
- app := cli.NewApp()
- app.EnableBashCompletion = true
- app.Commands = []cli.Command{
- {
- Name: "wat",
- },
- }
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-### Generated Help Text
-
-The default help flag (`-h/--help`) is defined as `cli.HelpFlag` and is checked
-by the cli internals in order to print generated help text for the app, command,
-or subcommand, and break execution.
-
-#### Customization
-
-All of the help text generation may be customized, and at multiple levels. The
-templates are exposed as variables `AppHelpTemplate`, `CommandHelpTemplate`, and
-`SubcommandHelpTemplate` which may be reassigned or augmented, and full override
-is possible by assigning a compatible func to the `cli.HelpPrinter` variable,
-e.g.:
-
-<!-- {
- "output": "Ha HA. I pwnd the help!!1"
-} -->
-``` go
-package main
-
-import (
- "fmt"
- "log"
- "io"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- // EXAMPLE: Append to an existing template
- cli.AppHelpTemplate = fmt.Sprintf(`%s
-
-WEBSITE: http://awesometown.example.com
-
-SUPPORT: support@awesometown.example.com
-
-`, cli.AppHelpTemplate)
-
- // EXAMPLE: Override a template
- cli.AppHelpTemplate = `NAME:
- {{.Name}} - {{.Usage}}
-USAGE:
- {{.HelpName}} {{if .VisibleFlags}}[global options]{{end}}{{if .Commands}} command [command options]{{end}} {{if .ArgsUsage}}{{.ArgsUsage}}{{else}}[arguments...]{{end}}
- {{if len .Authors}}
-AUTHOR:
- {{range .Authors}}{{ . }}{{end}}
- {{end}}{{if .Commands}}
-COMMANDS:
-{{range .Commands}}{{if not .HideHelp}} {{join .Names ", "}}{{ "\t"}}{{.Usage}}{{ "\n" }}{{end}}{{end}}{{end}}{{if .VisibleFlags}}
-GLOBAL OPTIONS:
- {{range .VisibleFlags}}{{.}}
- {{end}}{{end}}{{if .Copyright }}
-COPYRIGHT:
- {{.Copyright}}
- {{end}}{{if .Version}}
-VERSION:
- {{.Version}}
- {{end}}
-`
-
- // EXAMPLE: Replace the `HelpPrinter` func
- cli.HelpPrinter = func(w io.Writer, templ string, data interface{}) {
- fmt.Println("Ha HA. I pwnd the help!!1")
- }
-
- err := cli.NewApp().Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-The default flag may be customized to something other than `-h/--help` by
-setting `cli.HelpFlag`, e.g.:
-
-<!-- {
- "args": ["&#45;&#45halp"],
- "output": "haaaaalp.*HALP"
-} -->
-``` go
-package main
-
-import (
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- cli.HelpFlag = cli.BoolFlag{
- Name: "halp, haaaaalp",
- Usage: "HALP",
- EnvVar: "SHOW_HALP,HALPPLZ",
- }
-
- err := cli.NewApp().Run(os.Args)

-### Version Flag
-
-The default version flag (`-v/--version`) is defined as `cli.VersionFlag`, which
-is checked by the cli internals in order to print the `App.Version` via
-`cli.VersionPrinter` and break execution.
-
-#### Customization
-
-The default flag may be customized to something other than `-v/--version` by
-setting `cli.VersionFlag`, e.g.:
-
-<!-- {
- "args": ["&#45;&#45print-version"],
- "output": "partay version 19\\.99\\.0"
-} -->
-``` go
-package main
-
-import (
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-func main() {
- cli.VersionFlag = cli.BoolFlag{
- Name: "print-version, V",
- Usage: "print only the version",
- }
-
- app := cli.NewApp()
- app.Name = "partay"
- app.Version = "19.99.0"
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-Alternatively, the version printer at `cli.VersionPrinter` may be overridden, e.g.:
-
-<!-- {
- "args": ["&#45;&#45version"],
- "output": "version=19\\.99\\.0 revision=fafafaf"
-} -->
-``` go
-package main
-
-import (
- "fmt"
- "log"
- "os"
-
- "github.com/urfave/cli"
-)
-
-var (
- Revision = "fafafaf"
-)
-
-func main() {
- cli.VersionPrinter = func(c *cli.Context) {
- fmt.Printf("version=%s revision=%s\n", c.App.Version, Revision)
- }
-
- app := cli.NewApp()
- app.Name = "partay"
- app.Version = "19.99.0"
- err := app.Run(os.Args)
- if err != nil {
- log.Fatal(err)
- }
-}
-```
-
-#### Full API Example
-
-**Notice**: This is a contrived (functioning) example meant strictly for API
-demonstration purposes. Use of one's imagination is encouraged.

-### Combining short Bool options
-
-Traditional use of boolean options using their shortnames look like this:
-```
-# cmd foobar -s -o
-```
-
-Suppose you want users to be able to combine your bool options with their shortname. This
-can be done using the **UseShortOptionHandling** bool in your commands. Suppose your program
-has a two bool flags such as *serve* and *option* with the short options of *-o* and
-*-s* respectively. With **UseShortOptionHandling** set to *true*, a user can use a syntax
-like:
-```
-# cmd foobar -so
-```
-
-If you enable the **UseShortOptionHandling*, then you must not use any flags that have a single
-leading *-* or this will result in failures. For example, **-option** can no longer be used. Flags
-with two leading dashes (such as **--options**) are still valid.
