# About



After having used [prompt pure](https://github.com/sindresorhus/pure) for about a year, I felt that

a two-line prompt was not for me. Also not utilizing the right side of the terminal seemed a missed

opportunity. Still there is much to like: the elapsed time of a process, the coloring of the prompt

if the exit code of the process isn't 0, git integration. So I took "pure", mixed in my ideas of

what a prompt should look like and came up with "lean" - a 1 line prompt that stays out of your

face.



When lean starts, only 2 characters show on the screen '%' on the left and '~' on the right.

So lean is an evolution of pure, with the following changes:



*   Defaults to a very sparse setup, only showing information you need at the moment.

*   Comes with the perfect prompt character. Author went through the entire ASCII range to find it

    (and found it pretty quickly!)

*   Never displays your username (assuming you know who you are).

*   When tmux is active it shows a yellow 't' (I disabled the tmux bar, so this is some visual

    indication that tmux is active). If you don't want this indicator, you can always set

    `PROMPT_LEAN_TMUX=""` prior to loading this plugin (or prior to sourcing `zgen`, etc.).

*   Show remote host if logged in through SSH.

*   All in one line, most stuff in the right prompt, leaving the left prompt nice and clean

*   Shows background jobs (in the left prompt)

*   Show (dirty) git repos (can be disabled by setting `PROMPT_LEAN_VCS` to `0`). The branch name is

    truncated to 20 characters.

*   Shortens path if needed (longer then 70% of your screen). Two methods are provided: 'truncate'

    and 'shrink' (fish-style working directory). Set `PROMPT_LEAN_ABBR_METHOD` to choose the one you

    like the most (default is 'truncate'). Set `PROMPT_LEAN_PWD` to `0` to disable showing the path

    altogether.

*   Uses `PROMPT_LEAN_LEFT` and `PROMPT_LEAN_RIGHT` to allow customization of the left and/or right

    side of the prompt.

*   For a configurable insert-mode indicator, set the `PROMPT_LEAN_VIMODE` and

    `PROMPT_LEAN_VIMODE_FORMAT` variables. `PROMPT_LEAN_VIMODE_FORMAT` defaults to

    `"%F{red}[NORMAL]%f"`

*   Configurable colors to match your preferred scheme, by setting `PROMPT_LEAN_COLOR1` and

    `PROMPT_LEAN_COLOR2`

*   Use `PROMPT_LEAN_NOTITLE` to customize when the title should not be displayed. Useful for

    terminals that can not show title properly.

*   Use `PROMPT_LEAN_VCS` and `PROMPT_LEAN_PWD` to disable showing VCS info or the current working

    directory.



# Installation



## zgen



If you use [zgen](https://github.com/tarjoilija/zgen) you can add the following to your `~/.zshrc`:



~~~

zgen load miekg/lean

~~~



and force reload with `zgen reset && source ~/.zshrc`.



Note you must have the option PROMPT_SUBST set, see zshoptions(1).



## prezto



If you use [prezto](https://github.com/sorin-ionescu/prezto) you should do the following:



~~~

cd $ZPREZTODIR && git clone --recurse-submodules https://github.com/belak/prezto-contrib contrib

~~~



Then in `~/.zpreztorc` add `contrib-prompt` to module load list and select `lean` as a theme:



~~~

zstyle ':prezto:load' pmodule \

  ... \

  'contrib-prompt' \

  'prompt' \

  ...



zstyle ':prezto:module:prompt' theme 'lean'

~~~



`PROMPT_LEAN_LEFT` and `PROMPT_LEAN_RIGHT` should be customized in `~/.zshrc`. The rest variables

should be customized in `~/.zshenv`.



# Development



If you make any changes please run `make test` to ensure the (little) test suite is succesfull.
