Organizing Git Worktrees with Colocation

Colocated (or "bare repo + worktrees") pattern is one of the most popular and cleanest way to organize git worktrees. Here's how it works:

The Structure

myproject/              # Parent directory (not a checkout itself)
├── .bare/              # The bare git repo (the actual .git data)
├── .git                # A file (not dir) pointing to .bare

Storing Images and Demos in your Repo

In this quick walkthough you'll learn how to create a separate branch in your repo to house your screenshots and demo gifs for use in your master's readme.

How to

1. Clone a fresh copy of your repo

In order to prevent any loss of work it is best to clone the repo in a separate location to complete this task.

2. Create a new branch

Create a new branch in your repo by using git checkout --orphan assets

cmd+k is a normal keybindings in shells to clear. Cursor highjacks this keybindings for their generation in terminal. Update keybindings JSON to include the following to disable this behavior from Cursor.

{
    "key": "shift+cmd+k",
    "command": "cursorai.action.generateInTerminal",
    "when": "terminalFocus && terminalHasBeenCreated || terminalFocus && terminalProcessSupported"
  },
  {
 "key": "cmd+k",

The GitLens VSCode extension for inline git blames can eat IDE performance in large repos. I was able to significant improve it by removing the extension and using VSCode built-ins to achieve the same functionality.

"git.blame.editorDecoration.enabled": true,
"git.blame.editorDecoration.template": "${authorName}, ${authorDateAgo} • ${subject} (${hashShort})",
"git.blame.statusBarItem.enabled": true,
"git.blame.statusBarItem.template": "${authorName} (${authorDateAgo}) ${subject}"
