λ Pure

> Pretty, minimal and fast ZSH prompt based on Pure

Fork

This is a fork of marszall87/lambda-pure with following changes:
* Updated async.zsh so it works with newer versions of zsh
* Change default git arrows to the original ones: ⇣ and ⇡
* Add the current time to the end of the prompt
* Resets last exit code on an empty command

Overview

Most prompts are cluttered, ugly and slow. I wanted something visually pleasing that stayed out of my way.

$3

- Comes with the λ prompt character. Because lambdas are cool.
- Shows git branch and whether it's dirty (with a ×).
- Indicates when you have unpushed/unpulled git commits with up/down triangles. (Check is done asynchronously!)
- Shows current NodeJS version on the right side. (Check is done asynchronously!)
- Prompt character turns red if the last command didn't exit with 0.
- Command execution time will be displayed if it exceeds the set threshold.
- Username and host only displayed when in an SSH session.
- Shows the current path in the title and the current folder & command when a process is running.

Install

Can be installed with npm or manually. Requires git 2.0.0+ and ZSH 5.0.0+.

$3

``console
$ npm install --global @cwanner/lambda-pure-prompt
`

That's it. Skip to Getting started.

$3

1. Either…
- Clone this repo
- add it as a submodule, or
- just download lambda-pure.zsh and async.zsh

2. Symlink lambda-pure.zsh to somewhere in $fpath with the name prompt_lambda-pure_setup.

3. Symlink async.zsh in $fpath with the name async.

#### Example

`console
$ ln -s "$PWD/lambda-pure.zsh" /usr/local/share/zsh/site-functions/prompt_lambda-pure_setup
$ ln -s "$PWD/async.zsh" /usr/local/share/zsh/site-functions/async
`
Run echo $fpath to see possible locations.

For a user-specific installation (which would not require escalated privileges), simply add a directory to $fpath for that user:

`sh


.zshenv or .zshrc


fpath=( "$HOME/.zfunctions" $fpath )
`

Then install the theme there:

`console
$ ln -s "$PWD/lambda-pure.zsh" "$HOME/.zfunctions/prompt_lambda-pure_setup"
$ ln -s "$PWD/async.zsh" "$HOME/.zfunctions/async"
`




Getting started

Initialize the prompt system (if not so already) and choose lambda-pure:

`sh


.zshrc


autoload -U promptinit; promptinit
prompt lambda-pure
`

Options

$3

The max execution time of a process before its run time is shown when it exits. Defaults to 5 seconds.

$3

Set PURE_GIT_PULL=0 to prevent Pure from checking whether the current Git remote has been updated.

$3

Set PURE_GIT_UNTRACKED_DIRTY=0 to not include untracked files in dirtiness check. Only really useful on extremely huge repos like the WebKit repo.

$3

Time in seconds to delay git dirty checking for large repositories (git status takes > 2 seconds). The check is performed asynchronously, this is to save CPU. Defaults to 1800 seconds.

$3

Defines the prompt symbol. The default value is λ.

$3

Defines the git down arrow symbol. The default value is ⇣.

$3

Defines the git up arrow symbol. The default value is ⇡.

$3

Defines the git dirty symbol. The default value is ×.

Example

`sh


.zshrc

autoload -U promptinit; promptinit

optionally define some options

PURE_CMD_MAX_EXEC_TIME=10

prompt lambda-pure
`

Integration

$3

1. Symlink (or copy) lambda-pure.zsh to ~/.oh-my-zsh/custom/themes/lambda-pure.zsh-theme.
2. Set ZSH_THEME="lambda-pure" in your .zshrc file.

$3

Update your .zshrc file with the following two lines (order matters). Do not use the antigen theme function.

`console
$ antigen bundle mafredri/zsh-async
$ antigen bundle marszall87/lambda-pure
`

$3

Update your .zshrc file with the following two lines (order matters):

`console
$ antibody bundle mafredri/zsh-async
$ antibody bundle marszall87/lambda-pure
`

$3

Update your .zshrc file with the following two lines (order matters):

`console
$ zgen load mafredri/zsh-async
$ zgen load marszall87/lambda-pure
``
