complete

Package complete provides a tool for bash writing bash completion in go, and bash completion for the go command line.

Writing bash completion scripts is a hard work. This package provides an easy way to create bash completion scripts for any command, and also an easy way to install/uninstall the completion of the command.

Go Command Bash Completion

In ./cmd/gocomplete there is an example for bash completion for the go command line.

This is an example that uses the complete package on the go command - the complete package can also be used to implement any completions, see #usage.

Install

1. Type in your shell:

go get -u github.com/posener/complete/gocomplete
gocomplete -install

2. Restart your shell

Uninstall by gocomplete -uninstall

Features

• Complete go command, including sub commands and all flags.
• Complete packages names or .go files when necessary.
• Complete test names after -run flag.

Complete package

Supported shells:

• bash
• zsh
• fish

Usage

Assuming you have program called run and you want to have bash completion for it, meaning, if you type run then space, then press the Tab key, the shell will suggest relevant complete options.

In that case, we will create a program called runcomplete, a go program, with a func main() and so, that will make the completion of the run program. Once the runcomplete will be in a binary form, we could runcomplete -install and that will add to our shell all the bash completion options for run.

So here it is:

import "github.com/posener/complete"

func main() {

	// create a Command object, that represents the command we want
	// to complete.
	run := complete.Command{

		// Sub defines a list of sub commands of the program,
		// this is recursive, since every command is of type command also.
		Sub: complete.Commands{

			// add a build sub command
			"build": complete.Command {

				// define flags of the build sub command
				Flags: complete.Flags{
					// build sub command has a flag '-cpus', which
					// expects number of cpus after it. in that case
					// anything could complete this flag.
					"-cpus": complete.PredictAnything,
				},
			},
		},

		// define flags of the 'run' main command
		Flags: complete.Flags{
			// a flag -o, which expects a file ending with .out after
			// it, the tab completion will auto complete for files matching
			// the given pattern.
			"-o": complete.PredictFiles("*.out"),
		},

		// define global flags of the 'run' main command
		// those will show up also when a sub command was entered in the
		// command line
		GlobalFlags: complete.Flags{

			// a flag '-h' which does not expects anything after it
			"-h": complete.PredictNothing,
		},
	}

	// run the command completion, as part of the main() function.
	// this triggers the autocompletion when needed.
	// name must be exactly as the binary that we want to complete.
	complete.New("run", run).Run()
}

Self completing program

In case that the program that we want to complete is written in go we can make it self completing. Here is an example: ./example/self/main.go .

Sub Packages

• cmd: Package cmd used for command line options for the complete tool

• gocomplete: Package main is complete tool for the go command line

• match: Package match contains matchers that decide if to apply completion.
