# Budspencer theme
A theme for the 70s, makes fish even more powerful. It's equipped with a few
nice functions and key bindings to speed up your workflow.
## Demonstration video
[![video][screenshot]](http://vimeo.com/105546618)
## Requirements
You need an up-to-date fish shell version from [github][fish-git] or a
[nightly build][fish-nightly].
Non standard tools:
* xsel
* wmctrl
* git
* [taskwarrior][taskwarrior] (optional)
* [remind][remind] (optional)
## Configuration
### General configuration
The theme behaves similar to vim's airline/powerline plugins. Thus, 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, execute:
```
set -U fish_key_bindings fish_vi_key_bindings
```
### Colors
Redefine `$budspencer_colors` with the `set` command in order to change the
colors of the prompt.
Example:
```
set budspencer_colors 000000 333333 666666 ffffff ffff00 ff6600 ff0000 ff0033 3300ff 0000ff 00ffff
00ff00
```
will result in a prompt like this:
![color replace example][colors]
Two color schemes for bright and dark environments are predefined. You can
enable them with `day` and `night`, respectively.
### Command history
Commands that shouldn't appear in the command history are defined by a universal
list `$budspencer_nocmdhist`. Default:
```
set -U budspencer_nocmdhist c d ll ls m s
```
### Disable/reenable greeting
Disable:
```
set -U budspencer_nogreeting
```
Reenable:
```
set -e budspencer_nogreeting
```
## Outer prompt segments
- Vi mode is indicated by color of outer segments, cursor color also changes
if terminal supports it:
* blue: NORMAL mode
* yellow: INSERT mode
* magenta: VISUAL mode
## Left prompt segments
- Prompt line number
- Git repository information
- Status symbols
* ✻: keep track of this shell session, can be toggled with `#` to show the number of
the session within the sessions list
* ⌘: present working directory is in bookmark list, can be toggled with `#` to
show the number of the bookmark
* V: vi is parent process
* R: [ranger][ranger] is parent process
* ⚙: there are background jobs, can be toggled with `#` to show the amount of
background jobs
* : no write permissions in present working directory
* ⚔: there are tasks scheduled due today, can be toggled with `#` to
show the amount of tasks
* ⚑: there are appointments for today, can be toggled with `#` to
show the amount of appointments
* ✔: last command succeeded, can be toggled with `#` to show the status value
* ✘: last command failed, can be toggled with `#` to show the status value
* ⚡: superuser indicator
- Present working directory
## Right prompt segments
- Last command's duration time
- Git status symbols:
* ↑: git repository is ahead origin
* ↓: git repository is behind origin
* +: changes have been added to git index
* : files have been deleted in work tree
* ✱: files have been modified in work tree
* →: files have been renamed in git index
* ═: there are unmerged commits
* ●: there are untracked (new) files
* ✭: there are stashed commits
## Toggle prompt segments
The following shortcuts need vi-mode:
- Style of "present working directory"-segment can be toggled in NORMAL and in
VISUAL mode with space bar
* styles implemented:
- `short` (shows username, short hostname and truncated path; recommended in
most cases)
- `long` (shows username, full hostname and full path; useful for copy-paste
in ssh connections)
- `none` (shows nothing except small delimiter; useful for small terminals)
- If prompt is toggled with `#`, the IP address is shown instead of the
hostname.
* configurable by universal list `$budspencer_pwdstyle` (if not set, defaults to
`short long none`); note that changes to `$budspencer_pwdstyle` keep persistant as it's
a universal variable.
- Style of symbols can be toggled in NORMAL and in VISUAL mode with `#`
* styles implemented:
- `symbols` (shows status symbols)
- `numbers` (shows numbers instead of symbols in left prompt as well as amount of changes in
right git prompt)
## Quickly navigate in history of working directories
The function `d` shows the history as enumerated list. Unlike fish's builtin
`dirh`, `d` does not show any duplicates. Enter a number to jump to a directory
within the list.
The following shortcuts need vi-mode:
- Press `H` in NORMAL mode to change present working directory to previous
working directory in history.
- Press `L` in NORMAL mode to change present working directory to next working
directory in history.
## Quickly navigate in command history
The function `c` shows the command history as enumerated list similarly to
the `d` function. Selections are also paste into the X clipboard. It's possible
to load a command of a former prompt by giving the prompt line number as
argument.
## Bookmarks
A bookmark can be created with `mark`. It can be removed with `unmark`.
Bookmarks are universal and thus persistant.
A new shell automatically changes working directory on startup to newest bookmark.
`m` is a function that shows the bookmarks as enumerated list equivalently to `d`.
The following shortcuts need vi mode:
- Create a bookmark for present working directory with `m` in NORMAL mode.
- Remove a bookmark for present working directory with `M` in NORMAL mode.
## Edit commandline with your favorite editor
The function `edit-commandline` let you edit the commandline with your editor.
It makes the commandline as powerful as your editor. If `$EDITOR` is not set,
vi is used.
The following shortcut needs vi mode:
- Type `.` in NORMAL mode to edit commandline in editor.
## Sessions
Shell session can be stored with `s <session name>`. If a session with `session
name` already exists, the session with this name will be attached. If a session with
`session name` is already active within another terminal, this terminal will be
focussed.
A list of available sessions can be shown with `s`.
A session can be erased with `s -e <session name>`.
Type `s -d` to detach current session.
## Set window title
Just type `wt <title>`.
## TODO
- vi REPLACE mode, as soon as REPLACE mode is implemented within fish
