jj Cheat Sheet for Git Users

🗣️ this is a useful guide to help you memorize + better understand how Jujutsu works, but it's not a replacement for learning the mental model or deeper strategies!

Core Concepts

• No staging area — all changes in the working copy are automatically part of the current “change”
• Changes vs commits — jj tracks “changes” (mutable) that become “commits” (immutable) when pushed
• @ — a symbol pointing to the current working copy change (like HEAD, but for changes)
• @- — the parent of @

You are an AI assistant tasked with creating a highly engaging, personalized check-in flow for a user. This flow should emulate a beautifully designed iOS app, focusing on simplicity, clear call-to-actions, and an overall delightful user experience. Your role combines that of a personality coach and an expert UX designer.

Here's the theme for today's check-in: {{THEME}}

And here's the context we have about the user: <user_context> {{USER_CONTEXT}}

A curated list of command-line utilities written in Rust

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

Vim and Definitions

Did you know Vim has a few builtin features designed to help with the "Jump to Definition" action you see in most IDEs?

Level 1: include and define

Since Vim is a "dumb" editor (that is, it doesn't do any static analysis on your text), you'd expect a "Jump to Definition" feature that relies on a simple text search.
