Lambda 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.

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 ×.

`PURE_NODE_ENABLED`

Set PURE_NODE_ENABLED=0 to not display the NodeJS version.

Example

# .zshrc

autoload -U promptinit; promptinit

# optionally define some options
PURE_CMD_MAX_EXEC_TIME=10
