`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!

Make sure you have a working Go environment (go 1.1+ is *required*). [See the install instructions](http://golang.org/doc/install.html).

#### To Distribute
|
||||
|
||||
Copy and modify `autocomplete/bash_autocomplete` to use your program name
|
||||
rather than `$PROG` and have the user copy the file into
|
||||
`/etc/bash_completion.d/` (or automatically install it there if you are
|
||||
distributing a package). Alternatively you can just document that users should
|
||||
source the generic `autocomplete/bash_autocomplete` with `$PROG` set to your
|
||||
program name in their bash configuration.
|
||||
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

## 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.
