+# Change Log
+
+**ATTN**: This project uses [semantic versioning](http://semver.org/).
+
+## [Unreleased]
+
+## [1.18.0] - 2016-06-27
+### Added
+- `./runtests` test runner with coverage tracking by default
+- testing on OS X
+- testing on Windows
+- `UintFlag`, `Uint64Flag`, and `Int64Flag` types and supporting code
+
+### Changed
+- Use spaces for alignment in help/usage output instead of tabs, making the
+ output alignment consistent regardless of tab width
+
+### Fixed
+- Printing of command aliases in help text
+- Printing of visible flags for both struct and struct pointer flags
+- Display the `help` subcommand when using `CommandCategories`
+- No longer swallows `panic`s that occur within the `Action`s themselves when
+ detecting the signature of the `Action` field
+
+## [1.17.0] - 2016-05-09
+### Added
+- Pluggable flag-level help text rendering via `cli.DefaultFlagStringFunc`
+- `context.GlobalBoolT` was added as an analogue to `context.GlobalBool`
+- Support for hiding commands by setting `Hidden: true` -- this will hide the
+ commands in help output
+
+### Changed
+- `Float64Flag`, `IntFlag`, and `DurationFlag` default values are no longer
+ quoted in help text output.
+- All flag types now include `(default: {value})` strings following usage when a
+ default value can be (reasonably) detected.
+- `IntSliceFlag` and `StringSliceFlag` usage strings are now more consistent
+ with non-slice flag types
+- Apps now exit with a code of 3 if an unknown subcommand is specified
+ (previously they printed "No help topic for...", but still exited 0. This
+ makes it easier to script around apps built using `cli` since they can trust
+ that a 0 exit code indicated a successful execution.
+- cleanups based on [Go Report Card
+ feedback](https://goreportcard.com/report/github.com/urfave/cli)
+
+## [1.16.0] - 2016-05-02
+### Added
+- `Hidden` field on all flag struct types to omit from generated help text
+
+### Changed
+- `BashCompletionFlag` (`--enable-bash-completion`) is now omitted from
+generated help text via the `Hidden` field
+
+### Fixed
+- handling of error values in `HandleAction` and `HandleExitCoder`
+
+## [1.15.0] - 2016-04-30
+### Added
+- This file!
+- Support for placeholders in flag usage strings
+- `App.Metadata` map for arbitrary data/state management
+- `Set` and `GlobalSet` methods on `*cli.Context` for altering values after
+parsing.
+- Support for nested lookup of dot-delimited keys in structures loaded from
+YAML.
+
+### Changed
+- The `App.Action` and `Command.Action` now prefer a return signature of
+`func(*cli.Context) error`, as defined by `cli.ActionFunc`. If a non-nil
+`error` is returned, there may be two outcomes:
+ - If the error fulfills `cli.ExitCoder`, then `os.Exit` will be called
+ automatically
+ - Else the error is bubbled up and returned from `App.Run`
+- Specifying an `Action` with the legacy return signature of
+`func(*cli.Context)` will produce a deprecation message to stderr
+- Specifying an `Action` that is not a `func` type will produce a non-zero exit
+from `App.Run`
+- Specifying an `Action` func that has an invalid (input) signature will
+produce a non-zero exit from `App.Run`
+
+### Deprecated
+- <a name="deprecated-cli-app-runandexitonerror"></a>
+`cli.App.RunAndExitOnError`, which should now be done by returning an error
+that fulfills `cli.ExitCoder` to `cli.App.Run`.
+- <a name="deprecated-cli-app-action-signature"></a> the legacy signature for
+`cli.App.Action` of `func(*cli.Context)`, which should now have a return
+signature of `func(*cli.Context) error`, as defined by `cli.ActionFunc`.
+
+### Fixed
+- Added missing `*cli.Context.GlobalFloat64` method
+
+## [1.14.0] - 2016-04-03 (backfilled 2016-04-25)

## 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.

```
+### 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` branch
+
+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 the `v1` branch is an acceptable option, e.g.:
+
+```
+$ go get gopkg.in/urfave/cli.v1
+```
+
+``` go
+...
+import (
+ "gopkg.in/urfave/cli.v1" // imports as package "cli"
+)
+...
+```

## Getting Started

+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": ["--help"],
+ "output": "--config FILE, -c FILE"
+} -->
+```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.
+You can set alternate (or short) names for flags by providing a comma-delimited
+list for the `Name`. e.g.
+<!-- {
+ "args": ["--help"],
+ "output": "--lang value, -l value.*language for the greeting.*default: \"english\""
+} -->
``` go
-app.Flags = []cli.Flag {
- cli.StringFlag{
- Name: "lang, l",
- Value: "english",
- Usage: "language for the greeting",
- },

+ 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.
+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.
+<!-- {
+ "args": ["--help"],
+ "output": "language for the greeting.*APP_LANG"
+} -->
``` go
-app.Flags = []cli.Flag {
- cli.StringFlag{
- Name: "lang, l",
- Value: "english",
- Usage: "language for the greeting",
- EnvVar: "APP_LANG",
- },
+package main
+
+import (
+ "os"
+
+ "github.com/urfave/cli"
+)
+

+ app := cli.NewApp()

+ 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.

`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": ["--compgen"],
+ "output": "wat\nhelp\nh"
+} -->
+``` go

+
+### 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"
+ "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(S):
+ {{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")
+ }
+
+ cli.NewApp().Run(os.Args)
+}
+```
+
+The default flag may be customized to something other than `-h/--help` by
+setting `cli.HelpFlag`, e.g.:
+
+<!-- {
+ "args": ["--halp"],
+ "output": "haaaaalp.*HALP"
+} -->
+``` go
+package main
+
+import (
+ "os"
+
+ "github.com/urfave/cli"
+)
+
+func main() {
+ cli.HelpFlag = cli.BoolFlag{
+ Name: "halp, haaaaalp",
+ Usage: "HALP",
+ EnvVar: "SHOW_HALP,HALPPLZ",
+ }
+
+ 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 cusomized to something other than `-v/--version` by
+setting `cli.VersionFlag`, e.g.:
+
+<!-- {
+ "args": ["--print-version"],
+ "output": "partay version v19\\.99\\.0"
+} -->
+``` go
+package main
+
+import (
+ "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 = "v19.99.0"
+ app.Run(os.Args)
+}
+```
+
+Alternatively, the version printer at `cli.VersionPrinter` may be overridden, e.g.:
+
+<!-- {
+ "args": ["--version"],
+ "output": "version=v19\\.99\\.0 revision=fafafaf"
+} -->
+``` go
+package main
+
+import (
+ "fmt"
+ "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 = "v19.99.0"
+ app.Run(os.Args)
+}
+```
