document.addEventListener("DOMContentLoaded", () => {
  let idleMouseTimer;
  let forceMouseHide = false;

 document.body.style.cursor = "none";

Example list of first words to use in a git commit title

I like writing well-formed git commits that explain the intention behind why a code change was made.

Check out Chris Beams excellent How to Write a Git Commit Message if you haven't read it.

Anyway, for a project I've been working on I've gathered up 900+ commits that hold up a pretty high quality (except for one 😁). Let's look at some trends about these commits!

Most common first words in commit titles of a project

How to use <details> <summary> expandable content on GitHub with Markdown

Firstly, what is <details> <summary>?

The HTML Details Element (<details>) creates a disclosure widget in which information is visible only when the widget is toggled into an "open" state. A summary or label can be provided using the <summary> element. https://developer.mozilla.org/en-US/docs/Web/HTML/Element/details.

Updating a local diverged git branch to latest remote without reset --hard

Sometimes you have a branch checked out locally that someone else owns and they do a force push. Perhaps it's during a review when they have pushed all the needed fixups and got them approved. So now they squash and force-push the branch. It's time for you to take a new look at the updated commits, so you checkout the branch and try to update it.

The situation

$ git checkout some-topic-branch
$ git pull

How to get a fancier bash prompt PS1 inside a docker container

Today I wanted to make a recording of me running some commands inside a docker-container.

How to split a Git commit and preserve message using ORIG_HEAD

A colleague told me he'd accidentally committed something. Now he wanted to remove it from the previous commit and then put in a new commit. This is called splitting a commit, and here's the best way I know of how to do it.

Solution

1. git reset --soft HEAD~ Undo the last commit, but preserve "Changes to be committed"
2. git reset <some/path> Exclude what you want
3. git commit -C ORIG_HEAD Commit with the same message as before, which was stored in ORIG_HEAD

proj shell script project opener using fzf with tmux and tmuxinator

First you need a script like this in your terminal. It will detect all your projects, format them with a date when last used, sort them and pass through fzf. When a project has been selected it will cd to that directory and by default run tn which is another script for creating a new tmux session from the current directory. If you run proj something it will run that instead inside that directory.

proj() {
  local project_cmd=("$@")
