## Installation
You can download the latest binaries [here](https://github.com/liamg/bearings/releases/latest). Make sure you `chmod +x` the binary and place it somewhere in your `PATH`. Then follow the instructions for your shell below.
It is recommended to install font(s) which include powerline characters, especially [nerd-fonts](https://github.com/ryanoasis/nerd-fonts).
## Configuration
### Automatic (recommended)
You can automatically configure your shell by running `bearings install`. This will modify your shell configuration files in order to set bearings as your PS1 generator. For advanced configurations (e.g. templated dotfiles), you should use the manual methods below. It's always a good idea to back up your config files first!
If you'd like to install bearings to a shell other than the one you're using, you can specify it with the `-s/--shell` flag, e.g. `bearings install -s fish`.
### ZSH
```zsh
#bearings-auto:start
function preexec() {
if [[ $OSTYPE == 'darwin'* ]]; then
btimer=$(($(date +%s)*1000))
else
btimer=$(($(date +%s%N)/1000000))
fi
}
function configure_bearings() {
last=$?
elapsed=0
if [ $btimer ]; then
if [[ $OSTYPE == 'darwin'* ]]; then
now=$(($(date +%s)*1000))
else
now=$(($(date +%s%N)/1000000))
fi
elapsed=$(($now-$btimer))
unset btimer
fi
PROMPT="$(bearings prompt -s zsh -e ${last} -d ${elapsed} -j $(jobs | wc -l))"
}
[ ! "$TERM" = "linux" ] && precmd_functions+=(configure_bearings)
#bearings-auto:end
```
### Bash
```bash
#bearings-auto:start
if [[ $OSTYPE == 'darwin'* ]]; then
PS0='$(echo "$(($(date +%s)*1000))" > /tmp/bearings.$$)';
else
PS0='$(echo "$(($(date +%s%N)/1000000))" > /tmp/bearings.$$)';
fi
bearings_prompt() {
if [[ $OSTYPE == 'darwin'* ]]; then
NOW=$(($(date +%s)*1000))
else
NOW=$(($(date +%s%N)/1000000))
fi
START=$NOW
[[ -f /tmp/bearings.$$ ]] && START=$(cat /tmp/bearings.$$) && rm /tmp/bearings.$$
DURATION=$(($NOW - $START));
export PS1=$(bearings prompt -s bash -e $? -d $DURATION -j $(jobs -p | wc -l));
}
[[ ! "$TERM" = "linux" ]] && export PROMPT_COMMAND=bearings_prompt
#bearings-auto:end
```
### Fish
```fish
#bearings-auto:start
function fish_prompt
bearings prompt -s fish -e $status -d $CMD_DURATION -j (count (jobs -p))
end
#bearings-auto:end
```
## Customisation
The config file is read from `~/.config/bearings/config.yml`. You can create a default config file by running `bearings prompt` for the first time.
For completeness, here is the default config file:
```yaml
padding: 1
end:
divider:
fg: white
bg: black
lines_above: 1
modules:
- type: exitcode
failure_bg: '#bb4444'
failure_fg: '#ffffff'
show_success: true
success_bg: '#000000'
success_fg: '#ffffff'
success_output:
- type: duration
bg: '#ffffff'
fg: '#334488'
threshold: 3s
- type: cwd
bg: '#334488'
fg: '#aaaaaa'
label: %s
max_depth: 3
- type: git
bg: '#393939'
fg: '#777777'
```
You can find example configurations with screenshots for each in the [examples directory](_examples).
