provided that such additional attribution notices cannot be construed as
modifying the License.
You may add Your own copyright statement to Your modifications and may provide
additional or different license terms and conditions for use, reproduction, or

or consequential damages of any character arising as a result of this License or
out of the use or inability to use the Work (including but not limited to
damages for loss of goodwill, work stoppage, computer failure or malfunction, or
any and all other commercial damages or losses), even if such Contributor has
been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability.

offer, and charge a fee for, acceptance of support, warranty, indemnity, or
other liability obligations and/or rights consistent with this License. However,
in accepting such obligations, You may act only on Your own behalf and on Your

This is an open source project for commonly used functions for the Go programming language.
This package need >= **go 1.2**
Code Convention: based on [Go Code Convention](https://github.com/Unknwon/go-code-convention).
## Contribute
Your contribute is welcome, but you have to check following steps after you added some functions and commit them:
1. Make sure you wrote user-friendly comments for **all functions** .
2. Make sure you wrote test cases with any possible condition for **all functions** in file `*_test.go`.
3. Make sure you wrote benchmarks for **all functions** in file `*_test.go`.
4. Make sure you wrote useful examples for **all functions** in file `example_test.go`.
5. Make sure you ran `go test -bench="."` and got **PASS** .
## Performance
See results on [drone.io](https://drone.io/github.com/Unknwon/com/latest) by `go test -bench="."`.

Macaron [![Build Status](https://drone.io/github.com/Unknwon/macaron/status.png)](https://drone.io/github.com/Unknwon/macaron/latest) [![](http://gocover.io/_badge/github.com/Unknwon/macaron)](http://gocover.io/github.com/Unknwon/macaron)
=======================
![Macaron Logo](macaronlogo.png)
Package macaron is a high productive and modular design web framework in Go.
##### Current version: 0.5.0
## Getting Started
To install Macaron:
go get github.com/Unknwon/macaron
The very basic usage of Macaron:
```go
package main
import "github.com/Unknwon/macaron"
func main() {
m := macaron.Classic()
m.Get("/", func() string {
return "Hello world!"
})
m.Run()
}
```
## Features
- Powerful routing with suburl.
- Flexible routes combinations.
- Unlimited nested group routers.
- Directly integrate with existing services.
- Dynamically change template files at runtime.
- Allow to use in-memory template and static files.
- Easy to plugin/unplugin features with modular design.
- Handy dependency injection powered by [inject](https://github.com/codegangsta/inject).
- Better router layer and less reflection make faster speed.
## Middlewares
Middlewares allow you easily plugin/unplugin features for your Macaron applications.
There are already many [middlewares](https://github.com/macaron-contrib) to simplify your work:
- gzip - Gzip compression to all requests

# bpool [![GoDoc](https://godoc.org/github.com/oxtoacart/bpool?status.png)](https://godoc.org/github.com/oxtoacart/bpool)
Package bpool implements leaky pools of byte arrays and Buffers as bounded channels. It is based on the leaky buffer example from the Effective Go documentation: http://golang.org/doc/effective_go.html#leaky_buffer
## Install
`go get github.com/oxtoacart/bpool`
## Documentation
See [godoc.org](http://godoc.org/github.com/oxtoacart/bpool) or use `godoc github.com/oxtoacart/bpool`
## Example
```go
var bufpool *bpol.BufferPool
func main() {
bufpool = bpool.NewBufferPool(48)
}
func someFunction() error {
// Get a buffer from the pool
buf := bufpool.Get()
...
...
...
// Return the buffer to the pool
bufpool.Put(buf)
return nil
}
```

# 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.
You can view the API docs here:
http://godoc.org/github.com/codegangsta/cli
## 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 some bitchass 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)
}
}
...
```
#### 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",
},
}
```
#### 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",
},
}
```
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.
### Subcommands
Subcommands can be defined for a more git-like command line app.
```go
...
app.Commands = []cli.Command{
{
Name: "add",
ShortName: "a",
Usage: "add a task to the list",
Action: func(c *cli.Context) {
println("added task: ", c.Args().First())
},
},
{
Name: "complete",
ShortName: "c",
Usage: "complete a task on the list",
Action: func(c *cli.Context) {
println("completed task: ", c.Args().First())
},
},
{
Name: "template",
ShortName: "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",
ShortName: "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`
## 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 are 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.
