# cli.go
`cli.go` is 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!
## Installation
Make sure you have a working Go environment (go 1.1+ is *required*). [See the install instructions](http://golang.org/doc/install.html).
To install `cli.go`, simply run:
```
$ go get github.com/codegangsta/cli
```
Make sure your `PATH` includes to the `$GOPATH/bin` directory so your commands can be easily used:
```
export PATH=$PATH:$GOPATH/bin
```
## Getting Started
One of the philosophies behind `cli.go` is that an API should be playful and full of discovery. So a `cli.go` app can be as little as one line of code in `main()`.
``` go
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
cli.NewApp().Run(os.Args)
}
```
This app will run and show help text, but is not very useful. Let's give an action to execute and some help documentation:
``` go
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
app := cli.NewApp()
app.Name = "boom"
app.Usage = "make an explosive entrance"
app.Action = func(c *cli.Context) {
println("boom! I say!")
}
app.Run(os.Args)
}
```
Running this already gives you a ton of functionality, plus support for things like subcommands and flags, which are covered below.
## Example
Being a programmer can be a lonely job. Thankfully by the power of automation that is not the case! Let's create a greeter app to fend off our demons of loneliness!
Start by creating a directory named `greet`, and within it, add a file, `greet.go` with the following code in it:
``` go
package main
import (
"os"
"github.com/codegangsta/cli"
)
func main() {
app := cli.NewApp()
app.Name = "greet"
app.Usage = "fight the loneliness!"
app.Action = func(c *cli.Context) {
println("Hello friend!")
}
app.Run(os.Args)
}
```
Install our command to the `$GOPATH/bin` directory:
```
$ go install
```
Finally run our new command:
```
$ greet
Hello friend!
```
`cli.go` 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`.
``` go
...
app.Action = func(c *cli.Context) {
println("Hello", c.Args()[0])
}
...
```
### Flags
Setting and querying flags is simple.
``` go
...
app.Flags = []cli.Flag {
cli.StringFlag{
Name: "lang",
Value: "english",
Usage: "language for the greeting",
},
}
app.Action = func(c *cli.Context) {
name := "someone"
if len(c.Args()) > 0 {
name = c.Args()[0]
}
if c.String("lang") == "spanish" {
println("Hola", name)
} else {
println("Hello", name)
}
}
...
```
See full list of flags at http://godoc.org/github.com/codegangsta/cli
#### Alternate Names
You can set alternate (or short) names for flags by providing a comma-delimited list for the `Name`. e.g.
``` go
app.Flags = []cli.Flag {
cli.StringFlag{
Name: "lang, l",
Value: "english",
Usage: "language for the greeting",
},
}
```
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.
``` go
app.Flags = []cli.Flag {
cli.StringFlag{
Name: "lang, l",
Value: "english",
Usage: "language for the greeting",
EnvVar: "APP_LANG",
},
}
```
The `EnvVar` may also be given as a comma-delimited "cascade", where the first environment variable that resolves is used as the default.
``` go
app.Flags = []cli.Flag {
cli.StringFlag{
Name: "lang, l",
Value: "english",
Usage: "language for the greeting",
EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG",
},
}
```
### Subcommands
Subcommands can be defined for a more git-like command line app.
```go
...
app.Commands = []cli.Command{
{
Name: "add",
Aliases: []string{"a"},
Usage: "add a task to the list",
Action: func(c *cli.Context) {
println("added task: ", c.Args().First())
},
},
{
Name: "complete",
Aliases: []string{"c"},
Usage: "complete a task on the list",
Action: func(c *cli.Context) {
println("completed task: ", c.Args().First())
},
},
{
Name: "template",
Aliases: []string{"r"},
Usage: "options for task templates",
Subcommands: []cli.Command{
{
Name: "add",
Usage: "add a new template",
Action: func(c *cli.Context) {
println("new task template: ", c.Args().First())
},
},
{
Name: "remove",
Usage: "remove an existing template",
Action: func(c *cli.Context) {
println("removed task template: ", c.Args().First())
},
},
},
},
}
...
```
### 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.
```go
...
var 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) {
println("completed task: ", c.Args().First())
},
BashComplete: func(c *cli.Context) {
// This will complete if no args are passed
if len(c.Args()) > 0 {
return
}
for _, t := range tasks {
fmt.Println(t)
}
},
}
}
...
```
#### To Enable
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`
#### To Distribute
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).
## Contribution Guidelines
Feel free to put up a pull request to fix a bug or maybe add a feature. 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, I 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 have any questions feel free to link @codegangsta to the issue in question and we can review it together.
If you feel like you have contributed to the project but have not yet been added as a collaborator, I probably forgot to add you. Hit @codegangsta up over email and we will get it figured out.

Package uniuri
=====================
[![Build Status](https://travis-ci.org/dchest/uniuri.png)](https://travis-ci.org/dchest/uniuri)
```go
import "github.com/dchest/uniuri"
```
Package uniuri generates random strings good for use in URIs to identify
unique objects.
Example usage:
```go
s := uniuri.New() // s is now "apHCJBl7L1OmC57n"
```
A standard string created by New() is 16 bytes in length and consists of
Latin upper and lowercase letters, and numbers (from the set of 62 allowed
characters), which means that it has ~95 bits of entropy. To get more
entropy, you can use NewLen(UUIDLen), which returns 20-byte string, giving
~119 bits of entropy, or any other desired length.
Functions read from crypto/rand random source, and panic if they fail to
read from it.
Constants
---------
```go
const (
// Standard length of uniuri string to achive ~95 bits of entropy.
StdLen = 16
// Length of uniurl string to achive ~119 bits of entropy, closest
// to what can be losslessly converted to UUIDv4 (122 bits).
UUIDLen = 20
)
```
Variables
---------
```go
var StdChars = []byte("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789")
```
Standard characters allowed in uniuri string.
Functions
---------
### func New
```go
func New() string
```
New returns a new random string of the standard length, consisting of
standard characters.
### func NewLen
```go
func NewLen(length int) string
```
NewLen returns a new random string of the provided length, consisting of
standard characters.
### func NewLenChars
```go
func NewLenChars(length int, chars []byte) string
```
NewLenChars returns a new random string of the provided length, consisting
of the provided byte slice of allowed characters (maximum 256).

Usage
------------
Streaming File Cache for #golang
fscache allows multiple readers to read from a cache while its being written to. [blog post](https://djherbis.github.io/post/fscache/)
Using the Cache directly:
```go
package main
import (
"io"
"log"
"os"
"time"
"gopkg.in/djherbis/fscache.v0"
)
func main() {
// create the cache, keys expire after 1 hour.
c, err := fscache.New("./cache", 0755, time.Hour)
if err != nil {
log.Fatal(err.Error())
}
// wipe the cache when done
defer c.Clean()
// Get() and it's streams can be called concurrently but just for example:
for i := 0; i < 3; i++ {
r, w, err := c.Get("stream")
if err != nil {
log.Fatal(err.Error())
}
if w != nil { // a new stream, write to it.
go func(){
w.Write([]byte("hello world\n"))
w.Close()
}()
}
// the stream has started, read from it
io.Copy(os.Stdout, r)
r.Close()
}
}
```
A Caching Middle-ware:
```go
package main
import(
"net/http"
"time"
"gopkg.in/djherbis/fscache.v0"
)
func main(){
c, err := fscache.New("./cache", 0700, 0)
if err != nil {
log.Fatal(err.Error())
}
handler := func(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "%v: %s", time.Now(), "hello world")
}
http.ListenAndServe(":8080", fscache.Handler(c, http.HandlerFunc(handler)))
}
```
Installation
------------
```sh
go get gopkg.in/djherbis/fscache.v0

# amber
--
import "github.com/eknkc/amber"
Amber is an elegant templating engine for Go Programming Language
It is inspired from HAML and Jade
### Tags
A tag is simply a word:
html
is converted to
<html></html>
It is possible to add ID and CLASS attributes to tags:
div#main
span.time
are converted to
<div id="main"></div>
<span class="time"></span>
Any arbitrary attribute name / value pair can be added this way:
a[href="http://www.google.com"]
You can mix multiple attributes together
a#someid[href="/"][title="Main Page"].main.link Click Link
gets converted to
<a id="someid" class="main link" href="/" title="Main Page">Click Link</a>
It is also possible to define these attributes within the block of a tag
a
#someid
[href="/"]
[title="Main Page"]
.main
.link
| Click Link
### Doctypes
To add a doctype, use `!!!` or `doctype` keywords:
!!! transitional
// <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
or use `doctype`
doctype 5
// <!DOCTYPE html>
Available options: `5`, `default`, `xml`, `transitional`, `strict`, `frameset`, `1.1`, `basic`, `mobile`
### Tag Content
For single line tag text, you can just append the text after tag name:
p Testing!
would yield
<p>Testing!</p>
For multi line tag text, or nested tags, use indentation:
html
head
title Page Title
body
div#content
p
| This is a long page content
| These lines are all part of the parent p
a[href="/"] Go To Main Page
### Data
Input template data can be reached by key names directly. For example, assuming the template has been
executed with following JSON data:
{
"Name": "Ekin",
"LastName": "Koc",
"Repositories": [
"amber",
"dateformat"
],
"Avatar": "/images/ekin.jpg",
"Friends": 17
}
It is possible to interpolate fields using `#{}`
p Welcome #{Name}!
would print
<p>Welcome Ekin!</p>
Attributes can have field names as well
a[title=Name][href="/ekin.koc"]
would print
<a title="Ekin" href="/ekin.koc"></a>
### Expressions
Amber can expand basic expressions. For example, it is possible to concatenate strings with + operator:
p Welcome #{Name + " " + LastName}
Arithmetic expressions are also supported:
p You need #{50 - Friends} more friends to reach 50!
Expressions can be used within attributes
img[alt=Name + " " + LastName][src=Avatar]
### Variables
It is possible to define dynamic variables within templates,
all variables must start with a $ character and can be assigned as in the following example:
div
$fullname = Name + " " + LastName
p Welcome #{$fullname}
If you need to access the supplied data itself (i.e. the object containing Name, LastName etc fields.) you can use `$` variable
p $.Name
### Conditions
For conditional blocks, it is possible to use `if <expression>`
div
if Friends > 10
p You have more than 10 friends
else if Friends > 5
p You have more than 5 friends
else
p You need more friends
Again, it is possible to use arithmetic and boolean operators
div
if Name == "Ekin" && LastName == "Koc"
p Hey! I know you..
There is a special syntax for conditional attributes. Only block attributes can have conditions;
div
.hasfriends ? Friends > 0
This would yield a div with `hasfriends` class only if the `Friends > 0` condition holds. It is
perfectly fine to use the same method for other types of attributes:
div
#foo ? Name == "Ekin"
[bar=baz] ? len(Repositories) > 0
### Iterations
It is possible to iterate over arrays and maps using `each`:
each $repo in Repositories
p #{$repo}
would print
p amber
p dateformat
It is also possible to iterate over values and indexes at the same time
each $i, $repo in Repositories
p
.even ? $i % 2 == 0
.odd ? $i % 2 == 1
### Mixins
Mixins (reusable template blocks that accept arguments) can be defined:
mixin surprise
span Surprise!
mixin link($href, $title, $text)
a[href=$href][title=$title] #{$text}
and then called multiple times within a template (or even within another mixin definition):
div
+surprise
+surprise
+link("http://google.com", "Google", "Check out Google")
Template data, variables, expressions, etc., can all be passed as arguments:
+link(GoogleUrl, $googleTitle, "Check out " + $googleTitle)
### Imports
A template can import other templates using `import`:
a.amber
p this is template a
b.amber
p this is template b
c.amber
div
import a
import b
gets compiled to
div
p this is template a
p this is template b
### Inheritance
A template can inherit other templates. In order to inherit another template, an `extends` keyword should be used.
Parent template can define several named blocks and child template can modify the blocks.
master.amber
!!! 5
html
head
block meta
meta[name="description"][content="This is a great website"]
title
block title
| Default title
body
block content
subpage.amber
extends master
block title
| Some sub page!
block append meta
// This will be added after the description meta tag. It is also possible
// to prepend someting to an existing block
meta[name="keywords"][content="foo bar"]
block content
div#main
p Some content here

## Usage
```go
var DefaultOptions = Options{true, false}
var DefaultDirOptions = DirOptions{".amber", true}
```
#### func Compile
```go
func Compile(input string, options Options) (*template.Template, error)
```
Parses and compiles the supplied amber template string. Returns corresponding Go
Template (html/templates) instance. Necessary runtime functions will be injected
and the template will be ready to be executed.
#### func CompileFile
```go
func CompileFile(filename string, options Options) (*template.Template, error)
```
Parses and compiles the contents of supplied filename. Returns corresponding Go
Template (html/templates) instance. Necessary runtime functions will be injected
and the template will be ready to be executed.
#### func CompileDir
```go
func CompileDir(dirname string, dopt DirOptions, opt Options) (map[string]*template.Template, error)
```
Parses and compiles the contents of a supplied directory name. Returns a mapping of template name (extension stripped) to corresponding Go Template (html/template) instance. Necessary runtime functions will be injected and the template will be ready to be executed.
If there are templates in subdirectories, its key in the map will be it's path relative to `dirname`. For example:
```
templates/
|-- index.amber
|-- layouts/
|-- base.amber
```
```go
templates, err := amber.CompileDir("templates/", amber.DefaultDirOptions, amber.DefaultOptions)
templates["index"] // index.amber Go Template
templates["layouts/base"] // base.amber Go Template
```
By default, the search will be recursive and will match only files ending in ".amber". If recursive is turned off, it will only search the top level of the directory. Specified extension must start with a period.
#### type Compiler
```go
type Compiler struct {
// Compiler options
Options
}
```
Compiler is the main interface of Amber Template Engine. In order to use an
Amber template, it is required to create a Compiler and compile an Amber source
to native Go template.
compiler := amber.New()
// Parse the input file
err := compiler.ParseFile("./input.amber")
if err == nil {
// Compile input file to Go template
tpl, err := compiler.Compile()
if err == nil {
// Check built in html/template documentation for further details
tpl.Execute(os.Stdout, somedata)
}
}
#### func New
```go
func New() *Compiler
```
Create and initialize a new Compiler
#### func (*Compiler) Compile
```go
func (c *Compiler) Compile() (*template.Template, error)
```
Compile amber and create a Go Template (html/templates) instance. Necessary
runtime functions will be injected and the template will be ready to be
executed.
#### func (*Compiler) CompileString
```go
func (c *Compiler) CompileString() (string, error)
```
Compile template and return the Go Template source You would not be using this
unless debugging / checking the output. Please use Compile method to obtain a
template instance directly.
#### func (*Compiler) CompileWriter
```go
func (c *Compiler) CompileWriter(out io.Writer) (err error)
```
Compile amber and write the Go Template source into given io.Writer instance You
would not be using this unless debugging / checking the output. Please use
Compile method to obtain a template instance directly.
#### func (*Compiler) Parse
```go
func (c *Compiler) Parse(input string) (err error)
```
Parse given raw amber template string.
#### func (*Compiler) ParseFile
```go
func (c *Compiler) ParseFile(filename string) (err error)
```
Parse the amber template file in given path
#### type Options
```go
type Options struct {
// Setting if pretty printing is enabled.
// Pretty printing ensures that the output html is properly indented and in human readable form.
// If disabled, produced HTML is compact. This might be more suitable in production environments.
// Defaukt: true
PrettyPrint bool
// Setting if line number emiting is enabled
// In this form, Amber emits line number comments in the output template. It is usable in debugging environments.
// Default: false
LineNumbers bool
}
```
#### type DirOptions
```go
// Used to provide options to directory compilation
type DirOptions struct {
// File extension to match for compilation
Ext string
// Whether or not to walk subdirectories
Recursive bool
}
```

/*
Package amber is an elegant templating engine for Go Programming Language.
It is inspired from HAML and Jade.
Tags
A tag is simply a word:
html
is converted to
<html></html>
It is possible to add ID and CLASS attributes to tags:
div#main
span.time
are converted to
<div id="main"></div>
<span class="time"></span>
Any arbitrary attribute name / value pair can be added this way:
a[href="http://www.google.com"]
You can mix multiple attributes together
a#someid[href="/"][title="Main Page"].main.link Click Link
gets converted to
<a id="someid" class="main link" href="/" title="Main Page">Click Link</a>
It is also possible to define these attributes within the block of a tag
a
#someid
[href="/"]
[title="Main Page"]
.main
.link
| Click Link
Doctypes
To add a doctype, use `!!!` or `doctype` keywords:
!!! transitional
// <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
or use `doctype`
doctype 5
// <!DOCTYPE html>
Available options: `5`, `default`, `xml`, `transitional`, `strict`, `frameset`, `1.1`, `basic`, `mobile`
Tag Content
For single line tag text, you can just append the text after tag name:
p Testing!
would yield
<p>Testing!</p>
For multi line tag text, or nested tags, use indentation:
html
head
title Page Title
body
div#content
p
| This is a long page content
| These lines are all part of the parent p
a[href="/"] Go To Main Page
Data
Input template data can be reached by key names directly. For example, assuming the template has been
executed with following JSON data:
{
"Name": "Ekin",
"LastName": "Koc",
"Repositories": [
"amber",
"dateformat"
],
"Avatar": "/images/ekin.jpg",
"Friends": 17
}
It is possible to interpolate fields using `#{}`
p Welcome #{Name}!
would print
<p>Welcome Ekin!</p>
Attributes can have field names as well
a[title=Name][href="/ekin.koc"]
would print
<a title="Ekin" href="/ekin.koc"></a>
Expressions
Amber can expand basic expressions. For example, it is possible to concatenate strings with + operator:
p Welcome #{Name + " " + LastName}
Arithmetic expressions are also supported:
p You need #{50 - Friends} more friends to reach 50!
Expressions can be used within attributes
img[alt=Name + " " + LastName][src=Avatar]
Variables
It is possible to define dynamic variables within templates,
all variables must start with a $ character and can be assigned as in the following example:
div
$fullname = Name + " " + LastName
p Welcome #{$fullname}
If you need to access the supplied data itself (i.e. the object containing Name, LastName etc fields.) you can use `$` variable
p $.Name
Conditions
For conditional blocks, it is possible to use `if <expression>`
div
if Friends > 10
p You have more than 10 friends
else if Friends > 5
p You have more than 5 friends
else
p You need more friends
Again, it is possible to use arithmetic and boolean operators
div
if Name == "Ekin" && LastName == "Koc"
p Hey! I know you..
There is a special syntax for conditional attributes. Only block attributes can have conditions;
div
.hasfriends ? Friends > 0
This would yield a div with `hasfriends` class only if the `Friends > 0` condition holds. It is
perfectly fine to use the same method for other types of attributes:
div
#foo ? Name == "Ekin"
[bar=baz] ? len(Repositories) > 0
Iterations
It is possible to iterate over arrays and maps using `each`:
each $repo in Repositories
p #{$repo}
would print
p amber
p dateformat
It is also possible to iterate over values and indexes at the same time
each $i, $repo in Repositories
p
.even ? $i % 2 == 0
.odd ? $i % 2 == 1
Includes
A template can include other templates using `include`:
a.amber
p this is template a
b.amber
p this is template b
c.amber
div
include a
include b
gets compiled to
div
p this is template a
p this is template b
Inheritance
A template can inherit other templates. In order to inherit another template, an `extends` keyword should be used.
Parent template can define several named blocks and child template can modify the blocks.
master.amber
!!! 5
html
head
block meta
meta[name="description"][content="This is a great website"]
title
block title
| Default title
body
block content
subpage.amber
extends master
block title
| Some sub page!
block append meta
// This will be added after the description meta tag. It is also possible
// to prepend something to an existing block
meta[name="keywords"][content="foo bar"]
block content
div#main
p Some content here

# go-bindata-assetfs
Serve embedded files from [jteeuwen/go-bindata](https://github.com/jteeuwen/go-bindata) with `net/http`.
[GoDoc](http://godoc.org/github.com/elazarl/go-bindata-assetfs)
### Installation
Install with
$ go get github.com/jteeuwen/go-bindata/...
$ go get github.com/elazarl/go-bindata-assetfs/...
### Creating embedded data
Usage is identical to [jteeuwen/go-bindata](https://github.com/jteeuwen/go-bindata) usage,
instead of running `go-bindata` run `go-bindata-assetfs`.
The tool will create a `bindata_assetfs.go` file, which contains the embedded data.
A typical use case is
$ go-bindata-assetfs data/...
### Using assetFS in your code
The generated file provides an `assetFS()` function that returns a `http.Filesystem`
wrapping the embedded files. What you usually want to do is:
http.Handle("/", http.FileServer(assetFS()))
This would run an HTTP server serving the embedded files.
## Without running binary tool
You can always just run the `go-bindata` tool, and then
use
import "github.com/elazarl/go-bindata-assetfs"
...
http.Handle("/",
http.FileServer(
&assetfs.AssetFS{Asset: Asset, AssetDir: AssetDir, Prefix: "data"}))
to serve files embedded from the `data` directory.

# Change Log
**ATTN**: This project uses [semantic versioning](http://semver.org/).
## [Unreleased]
## [1.19.1] - 2016-11-21
### Fixed
- Fixes regression introduced in 1.19.0 where using an `ActionFunc` as
the `Action` for a command would cause it to error rather than calling the
function. Should not have a affected declarative cases using `func(c
*cli.Context) err)`.
- Shell completion now handles the case where the user specifies
`--generate-bash-completion` immediately after a flag that takes an argument.
Previously it call the application with `--generate-bash-completion` as the
flag value.
## [1.19.0] - 2016-11-19
### Added
- `FlagsByName` was added to make it easy to sort flags (e.g. `sort.Sort(cli.FlagsByName(app.Flags))`)
- A `Description` field was added to `App` for a more detailed description of
the application (similar to the existing `Description` field on `Command`)
- Flag type code generation via `go generate`
- Write to stderr and exit 1 if action returns non-nil error
- Added support for TOML to the `altsrc` loader
- `SkipArgReorder` was added to allow users to skip the argument reordering.
This is useful if you want to consider all "flags" after an argument as
arguments rather than flags (the default behavior of the stdlib `flag`
library). This is backported functionality from the [removal of the flag
reordering](https://github.com/urfave/cli/pull/398) in the unreleased version
2
- For formatted errors (those implementing `ErrorFormatter`), the errors will
be formatted during output. Compatible with `pkg/errors`.
### Changed
- Raise minimum tested/supported Go version to 1.2+
### Fixed
- Consider empty environment variables as set (previously environment variables
with the equivalent of `""` would be skipped rather than their value used).
- Return an error if the value in a given environment variable cannot be parsed
as the flag type. Previously these errors were silently swallowed.
- Print full error when an invalid flag is specified (which includes the invalid flag)
- `App.Writer` defaults to `stdout` when `nil`
- If no action is specified on a command or app, the help is now printed instead of `panic`ing
- `App.Metadata` is initialized automatically now (previously was `nil` unless initialized)
- Correctly show help message if `-h` is provided to a subcommand
- `context.(Global)IsSet` now respects environment variables. Previously it
would return `false` if a flag was specified in the environment rather than
as an argument
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
- `altsrc`s import paths were updated to use `gopkg.in/urfave/cli.v1`. This
fixes issues that occurred when `gopkg.in/urfave/cli.v1` was imported as well
as `altsrc` where Go would complain that the types didn't match
## [1.18.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user (backported)
## [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
## [1.17.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
## [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)
## [1.16.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
## [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

"""
The flag types that ship with the cli library have many things in common, and
so we can take advantage of the `go generate` command to create much of the
source code from a list of definitions. These definitions attempt to cover
the parts that vary between flag types, and should evolve as needed.
An example of the minimum definition needed is:
{
"name": "SomeType",
"type": "sometype",
"context_default": "nil"
}
In this example, the code generated for the `cli` package will include a type
named `SomeTypeFlag` that is expected to wrap a value of type `sometype`.
Fetching values by name via `*cli.Context` will default to a value of `nil`.
A more complete, albeit somewhat redundant, example showing all available
definition keys is:
{
"name": "VeryMuchType",
"type": "*VeryMuchType",
"value": true,
"dest": false,
"doctail": " which really only wraps a []float64, oh well!",
"context_type": "[]float64",
"context_default": "nil",
"parser": "parseVeryMuchType(f.Value.String())",
"parser_cast": "[]float64(parsed)"
}
The meaning of each field is as follows:
name (string) - The type "name", which will be suffixed with
`Flag` when generating the type definition
for `cli` and the wrapper type for `altsrc`
type (string) - The type that the generated `Flag` type for `cli`
is expected to "contain" as its `.Value` member
value (bool) - Should the generated `cli` type have a `Value`
member?
dest (bool) - Should the generated `cli` type support a
destination pointer?
doctail (string) - Additional docs for the `cli` flag type comment
context_type (string) - The literal type used in the `*cli.Context`
reader func signature
context_default (string) - The literal value used as the default by the
`*cli.Context` reader funcs when no value is
present
parser (string) - Literal code used to parse the flag `f`,
expected to have a return signature of
(value, error)
parser_cast (string) - Literal code used to cast the `parsed` value
returned from the `parser` code
