Free shell auto-completion

Usually this requires modifying ~/.bashrc in order to work. And very few people do that even for such complex interfaces as git.

So, requiring high effort and having low impact, this is given low priority, unless someone implements that and makes a pull request.

Check out infi.docopt_completion. It generates shell auto-completion for a given docopt utility.

easy_install infi.docopt_completion
docopt-completion [script name]

The code is available here:

@wiggin15 Test at docopt.__version__ = 0.6.1 but have problems, it does not work. at Ubuntu 12.04 32bit.
test the simple file docopt_example.py as follow:

 #!/usr/bin//env python
 # coding: utf-8

 """Usage:
     docopt_example.py tcp <host> <port> [--timeout=<seconds>]
     docopt_example.py serial <port> [--baud=9600] [--timeout=<seconds>]
     docopt_example.py -h | --help | --version

 """
 from docopt import docopt

 if __name__ == '__main__':
     arguments = docopt(__doc__, version='0.1.1rc')
     print arguments

The test command is:

sudo docopt-completion ./docopt_example.py  
Completion file written to /etc/bash_completion.d/docopt_example.py.sh

I think this means is OK, but still can not use tab-completion at ./docopt_example.py
So Which steps I was wrong?
Thanks!

You're right, looks like this happens because docopt-completion does not sanitize the "." in ".py". Please open an issue in the docopt-completion repository (link above) and I'll fix it. In the meantime you can change the name from docopt_example.py to docopt_example and see if that works.

Thanks! Cause notebook not at hand, will report it tomorrow morning.

Taking a note from a crystal library completion, if you pass in the option --completion it generates the bash necessary to define an auto completion method.

But if you notice, for autocompletion to work best, the library (docopt in this case) would need some convention as to the data types of the values. Currently the variable name is mostly used. So this could be tricky.

This is utterly wonderful. I knew about docopt for 3 years or so but only now made the connection to autogenerating tab completion in bash. May the bless you all.

For those who might come across this issue, I've written a simple (not complete) completion script for bash :

If your command is called xt, you simply have to add the following script, followed by completor xt

__auto_completor() {
	cmd="${COMP_WORDS[0]}"
	cur="${COMP_WORDS[COMP_CWORD]}"
	prev="${COMP_WORDS[COMP_CWORD-1]}"
	if [ "$prev" = "$cmd" ]
	then
		opts="$("$cmd" --help |  grep "    $cmd" | sed -E "s@      $cmd ([^ ]+)( .*)?@\1@g")"
		COMPREPLY=( $(compgen -W "${opts}" -- ${cur}) )
	else
		COMPREPLY=( $(compgen -f -- "$cur") )
	fi
	return 0
}

completor() {
	cmd="$1"
	complete -F "__auto_completor" "$cmd"
}
# End of "completion-library", you can now call "completor cmdname"

completor xt
