Trying to make coa (https://github.com/veged/coa) shell command auto-completion work.

README.mdown

1. I've made a coa-completion-dummy
2. ➤ ./coa-completion-dummy --ve
3. Press Tab and nothing happens

I guess I have to generate some shell script first and then put source some_script.sh in my .bashrc. README.md doesn't mention any of those, instead it says:

Cmd.completable Adds shell completion to command, adds "completion" subcommand, that makes all the magic.

coa-completion-dummy

#!/usr/bin/env node

require('coa').Cmd()
    .completable()
    .opt()
        .name('version')
        .short('v')
        .long('version')
        .flag()
        .act(function(opts) {
            return 42;
        })
        .end()
    .run(process.argv.slice(2));
