Nodeprompt

A smart Git prompt for your terminal powered by Node.js.

Requirements

System

Bash 3.2.x
Fish 2.5.x
Zsh 5.3
Node.js (tested with 0.10.x, 5.7.x, 6.9.x, 10.x).
Git (tested with 1.9.x, 2.7.x, 2.11.x, 2.14.x, 2.25.x).

Note: There is a good change Nodeprompt will work with other configurations — just give it a shot and let me know!

Font

Since v2.0.0 Nodeprompt requires some special (powerline) symbols to be supported by the terminal font to render properly.

Some fonts support those symbols (glyphs) out–of–the–box, for instance, Fira Code used in examples below. Many open–source fonts have been patched and can be downloaded from GitHub. If neither works for you, you can google "[your font name] powerline" because it's likely someone patched your favorite font and posted it on–line.

A note for iTerm 2 users: Make sure the powerline–compatible font is enabled in both Profiles > Text > Font and Profiles > Text > Non–ASCII Font.

Examples

A plain folder (no Git)

An empty Git repository

Unstaged changes

Staged, unstaged and untracked

Branch ahead of the remote

Merge conflict

Installation

Call npm install -g nodeprompt (or yarn global add nodeprompt).
Configure your shell:

Bash

Put the following line:
```
. nodeprompt-enable-bash
```
in your ~/.bashrc or ~/.bash_profile file. Re–open the terminal window or source the file, e.g. source ~/.bashrc.

Zsh

Put the following lines:
```
. nodeprompt-enable-zsh
```
in your ~/.zshrc file. Re–open the terminal window or source ~/.zshrc.

Fish

Create a symbolic link to the fish_prompt.fish function file:
```
ln -s /path/to/../nodeprompt/bin/fish_prompt.fish ~/.config/fish/functions/fish_prompt.fish
```
Re–open the terminal window.
Enjoy your beautiful prompt!

Configuration and customization

Nodeprompt is configurable and things like the length of the SHA-1 hash or the number of levels displayed in the path can be adjusted. It is also possible to create a new prompt template from scratch, if that's what you want to do tonight.

Note: You don't have to configure Nodeprompt. By default, it uses config.default.js.

The config file is a plain Node.js module. To configure your prompt, create a ~/.nodeprompt/config.user.js file with module.exports:

module.exports = {
    option: 'value'
};

or simply copy the default configuration and modify it. Refer to the documentation to learn more.

Using as a library

Nodeprompt can be used as a utility to obtain the status of the Git repository. Use the model property to build your own prompt or logger on top of the library:

const Nodeprompt = require( './lib/nodeprompt.js' );
const prompt = new Nodeprompt();

console.log( prompt.model );

> {
	pwd: '/Users/oleq/nodeprompt',
	home: '/Users/oleq',
	gitDir: '.git',
	isGit: true,
	hostname: 'MBP',
	username: 'oleq',
	path: [ '~', 'nodeprompt' ],
	namerev: 'v1.0',
	head: 'ref: refs/heads/v1.0',
	hash: 'b22bb89',
	mergeHead: '',
	isInit: false,
	isBisecting: false,
	isDetached: false,
	isMerging: false,
	modified: 2,
	added: 0,
	untracked: 0,
	ahead: 2,
	behind: 0,
	branch: 'v1.0',
	hasDiverged: false
}
