# Installation
## Bash completions
### Prerequisites
**yadm** completion only works if Git completions are also enabled.
Bash and Zsh completion only works if Git completions are also enabled.
### Homebrew
## Homebrew
If using `homebrew` to install **yadm**, completions should automatically be
handled if you also install `brew install bash-completion`. This might require
you to include the main completion script in your own bashrc file like this:
If using `homebrew` to install yadm, Bash, Zsh, and Fish completions should
automatically be installed. For Bash and Zsh, you also must install
`bash-completion` or `zsh-completions`. This might require you to include the
main completion script in your own shell configuration like this:
```bash
[ -f /usr/local/etc/bash_completion ] && source /usr/local/etc/bash_completion
```
### Manual installation
## Bash (manual installation)
Copy the completion script locally, and add this to you bashrc:
```bash
[ -f /full/path/to/yadm.bash_completion ] && source /full/path/to/yadm.bash_completion
[ -f /path/to/yadm/completion/bash/yadm ] && source /path/to/yadm/completion/bash/yadm
```
## Zsh completions
### Homebrew
If using `homebrew` to install **yadm**, completions should handled automatically.
### Manual installation
## Zsh (manual installation)
Add the `completion/zsh` folder to `$fpath` in `.zshrc`:
```zsh
fpath=(/full/path/to/yadm/completion/zsh $fpath)
fpath=(/path/to/yadm/completion/zsh $fpath)
autoload -U compinit
compinit
```
### Installation using [zplug](https://github.com/b4b4r07/zplug)
## Zsh (using [zplug](https://github.com/b4b4r07/zplug))
Load `_yadm` as a plugin in your `.zshrc`:
```zsh
fpath=("$ZPLUG_HOME/bin" $fpath)
zplug "TheLocehiliosan/yadm", rename-to:_yadm, use:"completion/yadm.zsh_completion", as:command, defer:2
zplug "TheLocehiliosan/yadm", use:"completion/zsh/_yadm", as:command, defer:2
```
## Fish completions
### Manual installation
Copy the completion script `yadm.fish_completion` locally, rename it to `yadm.fish`, and add it to any folder within `$fish_complete_path`. For example, for local installation, you can copy it to `$HOME/.config/fish/completions/` and it will be loaded when `yadm` is invoked.
## Fish (manual installation)
Copy the completion script `yadm.fish` to any folder within `$fish_complete_path`. For example, for local installation, you can copy it to `$HOME/.config/fish/completions/` and it will be loaded when `yadm` is invoked.
