Git Tutor

Build Status

Generate step-by-step markdown tutorials from your git history

Motivation

There is tons of tutorials on medium, personal blogs etc. Writing detailed and complete guide how to build things is kinda hard and people are lazy, so those tutorials sometimes incomplete, code examples don't work as-is (some "prerequisite" step was not included in tutorial), sometimes it walks you through only some peices of code and you can find the rest in repo. But you have no idea how the rest works.

Git is a perfect tool to build smth incrementally (commits). git-tutor walks through commit history and generates markdown, placing commit message first, content of a commit afterwards. Write markdown to your commit messages – have a nice tutorial later with single command

Example tutorials

Some rules

  • keep commits small and explain almost every line of code you're writing
  • write markdown to your commit messages
  • don't skip anything. Simple copy-paste should work to reproduce the result of your tutorial
  • writing code is fun. Explaining how code works is even more of fun

Installation

npm i -g nodegit
npm i -g git-tutor

Usage

git-tutor . > README.md

Tips and tricks

I don't like commiting every line of code. What should I do to keep tutorial clean?

That's fine, I don't like it either. You can use git add -p and split your work into smaller chunks later

Git treats # as a comment by default

To be able to use this symbol and add headings you should reconfigure git cleanup symbol

git config commit.cleanup whitespace

What if I want to leave general comment/explanation without any code

Git allows commits without any content

git commit --allow-empty

How to use my favorite editor for writing markdown

Writing a lot of markdown is not really convenient in default git editor like vi, I prefer doing it in vscode as it allows to preview parsed markdown with all styling applied. To use vscode as git editor

  • Install code command in $PATH (Shift + CMD + P => Search for PATH)
  • git config core.editor "code --wait"

Default commit message template contains status in comment, how to remove it

You can pass --no-status flag to a commit command, this will strip those commented lines

git commit --no-status

You can also use your custom commit template:

  • create empty file and place it somwhere in your file system (e.g. ~/.gitmsg)
  • git config commit.template ~/.gitmsg

Unsolved issues

  • i18n (cherry-pick to new locale branch with translation?)
  • updates to previous commits (rebase works, but not convenient)
  • collobaration
