Shell completions for your program made easy.
## Installation
```shell
pip install completions
# install lastest version using poetry
git clone https://github.com/pwwang/completions
cd completions
poetry install
```
## Usage
### Defining your completions
You may define your completions, basically commands and options, by following schema (showed in `yaml`, but can be any format supported by [`python-simpleconf`][12]:
`example.yaml`
```yaml
program:
# your program, or path to your program
name: completions-example
desc: Shell completions for your program made easy.
# whether global options should be inherited by commands
inherit: true
# options or global options if you have commands
options:
-s: The shell, one of bash, fish, zsh and auto.
--shell: The shell, one of bash, fish, zsh and auto.
-a: Automatically write completions to destination file.
--auto: Automatically write completions to destination file.
commands:
# No other options for command, give the description
self: Generate completions for myself.
generate:
desc: Generate completions from configuration files.
options:
-c: The configuration file to load.
--config: The configuration file to load.
```
How it looks like in `fish`:
![command][13]
![option][14]
### Generating completion scripts
- Bash
```shell
> completions generate --shell bash \
--config example.yaml > ~/bash_completion.d/completions.bash-completion
```
You may need to `source` it in your `.bashrc` and restart your shell for the changes to take effect.
- Fish
```shell
> completions generate --shell fish \
--config example.yaml > ~/.config/fish/completions/completions.fish
```
You may need to restart your shell for the changes to take effect.
- Zsh
```shell
> completions generate --shell zsh \
--config example.yaml > ~/.zsh-completions/_completions
```
Make sure `fpath+=~/.zsh-completions` is put before `compinit` in you `.zshrc`
### Saving completions scripts automatically
- Bash
```shell
> completions generate --shell bash --config example.yaml --auto
```
- Fish
```shell
> completions generate --shell fish --config example.yaml --auto
```
- Zsh
```shell
> completions generate --shell zsh --config example.yaml --auto
```
### Python API
```python
from completions import Completions
completions = Completions(
# if not given, will be read from sys.argv[0]
name = 'completions',
# Add global options to commands
inherit = True,
desc = 'Shell completions for your program made easy.')
completions.addOption(
['-s', '--shell'],
'The shell, one of bash, fish, zsh and auto.')
completions.addOption(
['-a', '--auto'],
'Automatically write completions to destination file.')
completions.addCommand(
'self', 'Generate completions for myself.')
completions.addCommand(
'generate', 'Generate completions from configuration files.')
completions.command('generate').addOption(
['-c', '--config'], 'The configuration file to load.')
completions.generate(shell = 'fish', auto = False)
