# XHandler
[![godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](https://godoc.org/github.com/rs/xhandler) [![license](http://img.shields.io/badge/license-MIT-red.svg?style=flat)](https://raw.githubusercontent.com/rs/xhandler/master/LICENSE) [![Build Status](https://travis-ci.org/rs/xhandler.svg?branch=master)](https://travis-ci.org/rs/xhandler) [![Coverage](http://gocover.io/_badge/github.com/rs/xhandler)](http://gocover.io/github.com/rs/xhandler)
XHandler is a bridge between [net/context](https://godoc.org/golang.org/x/net/context) and `http.Handler`.
It lets you enforce `net/context` in your handlers without sacrificing compatibility with existing `http.Handlers` nor imposing a specific router.
Thanks to `net/context` deadline management, `xhandler` is able to enforce a per request deadline and will cancel the context when the client closes the connection unexpectedly.
You may create your own `net/context` aware handler pretty much the same way as you would do with http.Handler.
Read more about xhandler on [Dailymotion engineering blog](http://engineering.dailymotion.com/our-way-to-go/).
## Installing
go get -u github.com/rs/xhandler
## Usage
```go
package main
import (
"log"
"net/http"
"time"
"github.com/rs/cors"
"github.com/rs/xhandler"
"golang.org/x/net/context"
)
type myMiddleware struct {
next xhandler.HandlerC
}
func (h myMiddleware) ServeHTTPC(ctx context.Context, w http.ResponseWriter, r *http.Request) {
ctx = context.WithValue(ctx, "test", "World")
h.next.ServeHTTPC(ctx, w, r)
}
func main() {
c := xhandler.Chain{}
// Add close notifier handler so context is cancelled when the client closes
// the connection
c.UseC(xhandler.CloseHandler)
// Add timeout handler
c.UseC(xhandler.TimeoutHandler(2 * time.Second))
// Middleware putting something in the context
c.UseC(func(next xhandler.HandlerC) xhandler.HandlerC {
return myMiddleware{next: next}
})
// Mix it with a non-context-aware middleware handler
c.Use(cors.Default().Handler)
// Final handler (using handlerFuncC), reading from the context
xh := xhandler.HandlerFuncC(func(ctx context.Context, w http.ResponseWriter, r *http.Request) {
value := ctx.Value("test").(string)
w.Write([]byte("Hello " + value))
})
// Bridge context aware handlers with http.Handler using xhandler.Handle()
http.Handle("/test", c.Handler(xh))
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatal(err)
}
}
```
### Using xmux
Xhandler comes with an optional context aware [muxer](https://github.com/rs/xmux) forked from [httprouter](https://github.com/julienschmidt/httprouter):
```go
package main
import (
"fmt"
"log"
"net/http"
"time"
"github.com/rs/xhandler"
"github.com/rs/xmux"
"golang.org/x/net/context"
)
func main() {
c := xhandler.Chain{}
// Append a context-aware middleware handler
c.UseC(xhandler.CloseHandler)
// Another context-aware middleware handler
c.UseC(xhandler.TimeoutHandler(2 * time.Second))
mux := xmux.New()
// Use c.Handler to terminate the chain with your final handler
mux.GET("/welcome/:name", xhandler.HandlerFuncC(func(ctx context.Context, w http.ResponseWriter, req *http.Request) {
fmt.Fprintf(w, "Welcome %s!", xmux.Params(ctx).Get("name"))
}))
if err := http.ListenAndServe(":8080", c.Handler(mux)); err != nil {
log.Fatal(err)
}
}
```
See [xmux](https://github.com/rs/xmux) for more examples.
## Context Aware Middleware
Here is a list of `net/context` aware middleware handlers implementing `xhandler.HandlerC` interface.
Feel free to put up a PR linking your middleware if you have built one:
| Middleware | Author | Description |
| ---------- | ------ | ----------- |
| [xmux](https://github.com/rs/xmux) | [Olivier Poitrey](https://github.com/rs) | HTTP request muxer |
| [xlog](https://github.com/rs/xlog) | [Olivier Poitrey](https://github.com/rs) | HTTP handler logger |
| [xstats](https://github.com/rs/xstats) | [Olivier Poitrey](https://github.com/rs) | A generic client for service instrumentation |
| [xaccess](https://github.com/rs/xaccess) | [Olivier Poitrey](https://github.com/rs) | HTTP handler access logger with [xlog](https://github.com/rs/xlog) and [xstats](https://github.com/rs/xstats) |
| [cors](https://github.com/rs/cors) | [Olivier Poitrey](https://github.com/rs) | [Cross Origin Resource Sharing](http://www.w3.org/TR/cors/) (CORS) support |

# Change Log
**ATTN**: This project uses [semantic versioning](http://semver.org/).
## [Unreleased]
## [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/codegangsta/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)
### Added
- Codebeat badge
- Support for categorization via `CategorizedHelp` and `Categories` on app.
### Changed
- Use `filepath.Base` instead of `path.Base` in `Name` and `HelpName`.
### Fixed
- Ensure version is not shown in help text when `HideVersion` set.

cli is a simple, fast, and fun package for building command line apps in Go. The goal is to enable developers to write fast and distributable command line applications in an expressive way.
## 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!

See full list of flags at http://godoc.org/github.com/codegangsta/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
cli.StringFlag{
Name: "config, c",
Usage: "Load configuration from `FILE`",
}
```
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.
@ -238,6 +277,49 @@ app.Flags = []cli.Flag {
}
```
#### Values from alternate input sources (YAML and others)
There is a separate package altsrc that adds support for getting flag values from other input sources like YAML.
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 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:
``` go
command := &cli.Command{
Name: "test-cmd",
Aliases: []string{"tc"},
Usage: "this is for testing",
Description: "testing",
Action: func(c *cli.Context) error {
// Action to run
return nil
},
Flags: []cli.Flag{
NewIntFlag(cli.IntFlag{Name: "test"}),
cli.StringFlag{Name: "load"}},
}
command.Before = InitInputSourceWithContext(command.Flags, NewYamlSourceFromFlagFunc("load"))
err := command.Run(c)

### 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
...
app.Commands = []cli.Command{
{
Name: "noop",
},
{
Name: "add",
Category: "template",
},
{
Name: "remove",
Category: "template",
},
}
...
```
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 (
"os"
"github.com/codegangsta/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 {

return cli.NewExitError("it is not in the soup", 86)

### Generated Help Text 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/codegangsta/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}}

COPYRIGHT:
{{.Copyright}}
{{end}}{{if .Version}}
VERSION:
{{.Version}}

`
// 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)
}
```
