lambda-pure-prompt

λ Pure

Pretty, minimal and fast ZSH prompt based on Pure

Overview

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

Why?

• 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+.

npm

$ npm install --global lambda-pure-prompt

That's it. Skip to Getting started.

Manually

1. Either…

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

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

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

Example

$ 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:

# .zshenv or .zshrc
fpath=( "$HOME/.zfunctions" $fpath )

Then install the theme there:

$ 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:

# .zshrc
autoload -U promptinit; promptinit
prompt lambda-pure

Options

PURE_CMD_MAX_EXEC_TIME

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

PURE_GIT_PULL

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

PURE_GIT_UNTRACKED_DIRTY

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.

PURE_GIT_DELAY_DIRTY_CHECK

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.

PURE_PROMPT_SYMBOL

Defines the prompt symbol. The default value is λ.

PURE_GIT_DOWN_ARROW

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

PURE_GIT_UP_ARROW

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

PURE_GIT_DIRTY

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

Example

# .zshrc

autoload -U promptinit; promptinit

# optionally define some options
PURE_CMD_MAX_EXEC_TIME=10

prompt lambda-pure

Integration

oh-my-zsh

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.

antigen

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

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

antibody

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

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

zgen

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

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