# budspencer theme
Translation of zsh's prezto [budspencer theme][budspencer].
## Configuration
The theme behaves similar to vim's airline/powerline plugins. It needs a
[powerline font][font]. Although it works with emacs mode, it's more powerful
with vi mode. In order to enable vi mode, put the following lines into
`$HOME/.config/fish/config.fish` before `set fish_path $HOME/.oh-my-fish`:
```
set -e fish_key_bindings
set -U fish_key_bindings fish_vi_key_bindings
```
## Left prompt segments
- Vi mode indicator
- Git repository information
- Status symbols
* V: vi is parent process
* R: [ranger][ranger] is parent process
* ⚙: there are background jobs
* : no write permissions in present working directory
* ✔: last command succeeded
* ✘: last command failed
* ⚡: superuser indicator
## Right prompt segments
- Last command's duration time
- Git status
* style can be toggled in NORMAL and in VISUAL mode with `#` between
- `symbols` (shows git status symbols, see below)
- `counts` (shows amount of files that are affected)
* symbols:
- ↑: git repository is ahead origin
- ↓: git repository is behind origin
- +: new files were added
- –: files have been deleted
- ✱: files have been modified
- →: files have been renamed
- ═: there are unmerged commits
- ●: there are untracked files
- ✭: there are stashed commits
- Present working directory
* style can be toggled in NORMAL and in VISUAL mode with space bar
* styles implemented:
- `short` (show truncated path)
- `long` (show full path)
- `none` (show nothing)
* configurable by global array `$PWDSTYLE` (if not set, defaults to `short long none`)
## Screenshot

## TODO
- vi REPLACE mode, as soon as REPLACE mode is implemented within fish
