Bash Completion Example using Cobra Command API

This example demonstrates how to use bash completion along with Cobra Command API.

The sample application

A sample application is produced here, named bashcomp.

It demonstrates an approach to integrate bash completion with a Go application using Cobra.

In this example, the complete function is defined in a separate shell script file named bash_completion.sh.

The contents from bash_completion.sh will be bound to the BashCompletionEncoded variable at build time, allowing you to write your complete function more easily.

Building the bashcomp application

To build the application and produce a bash completion shell script, run;

make

After building it, you can simply source the produced bashcomp.bash.inc file, like:

source bashcomp.bash.inc

Running and validating auto complete options

Type bashcomp <tab><tab> and you will see the list of available options. If you want to try a more specific one, type: bashcomp thanks <tab><tab>.

NOTE:

Remember to install bashcomp to a directory that is part of your PATH,
if you use it in current directory with ./ completion won't work.
