shtab
=====

- What: Automatically generate shell tab completion scripts for Python CLI apps
- Why: Speed & correctness. Alternatives like
`argcomplete `_ and
`pyzshcomplete `_ are slow and have
side-effects
- How: ``shtab`` processes an ``argparse.ArgumentParser`` object to generate a
tab completion script for your shell

Features
--------

- Outputs tab completion scripts for

- ``bash``
- ``zsh``
- ``tcsh``

- Supports

- `argparse `_
- `docopt `_ (via `argopt `_)

- Supports arguments, options and subparsers
- Supports choices (e.g. ``--say={hello,goodbye}``)
- Supports file and directory path completion
- Supports custom path completion (e.g. ``--file={*.txt}``)

Installation
------------

Choose one of:

- ``pip install shtab``, or
- ``conda install -c conda-forge shtab``

See `operating system-specific instructions in the docs `_.

Usage
-----

There are two ways of using ``shtab``:

- `CLI Usage `_: ``shtab``'s own CLI interface for external applications

- may not require any code modifications whatsoever
- end-users execute ``shtab your_cli_app.your_parser_object``

- `Library Usage `_: as a library integrated into your CLI application

- adds a couple of lines to your application
- argument mode: end-users execute ``your_cli_app --print-completion {bash,zsh,tcsh}``
- subparser mode: end-users execute ``your_cli_app completion {bash,zsh,tcsh}``

Examples
--------

See `the docs for usage examples `_.

FAQs
----

Not working? Check out `frequently asked questions `_.

Alternatives
------------

- `argcomplete `_

- executes the underlying script *every* time ```` is pressed (slow and
has side-effects)
- only provides ``bash`` completion

- `pyzshcomplete `_

- executes the underlying script *every* time ```` is pressed (slow and
has side-effects)
- only provides ``zsh`` completion

- `click `_

- different framework completely replacing the builtin ``argparse``
- solves multiple problems (rather than POSIX-style "do one thing well")

Contributions
-------------

Please do open `issues `_ & `pull requests `_! Some ideas:

- support ``fish``
- support ``powershell``

See
`CONTRIBUTING.md `_
for more guidance.
