Pretty, minimal and fast ZSH prompt based on Pure

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

• 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.

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

$ npm install --global lambda-pure-prompt

That's it. Skip to Getting started.

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.

$ 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"

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

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

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

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

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.

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.

Defines the prompt symbol. The default value is λ.

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

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

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

Set PURE_NODE_ENABLED=0 to not display the NodeJS version.

# .zshrc

autoload -U promptinit; promptinit

# optionally define some options
PURE_CMD_MAX_EXEC_TIME=10

prompt lambda-pure

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.

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

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

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

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

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