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`. 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` +with `sort`. + +For example this: + + +``` go +package main + +import ( + "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`", + }, + } + + sort.Sort(cli.FlagsByName(app.Flags)) + + app.Run(os.Args) +} +``` + +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. + + +``` 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", + EnvVar: "APP_LANG", + }, + } + + app.Run(os.Args) +} +``` + +The `EnvVar` may also be given as a comma-delimited "cascade", where the first +environment variable that resolves is used as the default. + + +``` 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", + EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG", + }, + } + + app.Run(os.Args) +} +``` + +#### 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.

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/cmd/sl-feeds/vendor/github.com/urfave/cli/altsrc/altsrc.go b/cmd/sl-feeds/vendor/github.com/urfave/cli/altsrc/altsrc.go new file mode 100644 index 0000000..ac34bf6 --- /dev/null +++ b/cmd/sl-feeds/vendor/github.com/urfave/cli/altsrc/altsrc.go @@ -0,0 +1,3 @@ +package altsrc + +//go:generate python ../generate-flag-types altsrc -i ../flag-types.json -o flag_generated.go diff --git a/cmd/sl-feeds/vendor/github.com/urfave/cli/altsrc/flag.go b/cmd/sl-feeds/vendor/github.com/urfave/cli/altsrc/flag.go new file mode 100644 index 0000000..84ef009 --- /dev/null +++ b/cmd/sl-feeds/vendor/github.com/urfave/cli/altsrc/flag.go @@ -0,0 +1,261 @@ +package altsrc + +import ( + "fmt" + "strconv" + "strings" + "syscall" + + "gopkg.in/urfave/cli.v1" +) + +// FlagInputSourceExtension is an extension interface of cli.Flag that +// allows a value to be set on the existing parsed flags. +type FlagInputSourceExtension interface { + cli.Flag + ApplyInputSourceValue(context *cli.Context, isc InputSourceContext) error +} + +// ApplyInputSourceValues iterates over all provided flags and +// executes ApplyInputSourceValue on flags implementing the +// FlagInputSourceExtension interface to initialize these flags +// to an alternate input source. +func ApplyInputSourceValues(context *cli.Context, inputSourceContext InputSourceContext, flags []cli.Flag) error { + for _, f := range flags { + inputSourceExtendedFlag, isType := f.(FlagInputSourceExtension) + if isType { + err := inputSourceExtendedFlag.ApplyInputSourceValue(context, inputSourceContext) + if err != nil { + return err + } + } + } + + return nil +} + +// InitInputSource is used to to setup an InputSourceContext on a cli.Command Before method.
