Language aware diff on GitHub PRs
Hi HN! We were frustrated with text diffs on GitHub PRs, so we made DiffLens (https://github.com/marketplace/difflens). DiffLens constructs an Abstract Syntax Tree for each file, and uses that semantic information to intelligently diff changes. Checkout the demo on our website (https://www.difflens.com). Getting started with DiffLens is easy! Simply install the app on your repositories. The next time you open a PR, DiffLens will automatically create a diff for your changes. If you review code, especially TypeScript, JavaScript or CSS, give DiffLens a try! We're…

Pipe the output of a `diff` command to Diffswarm to get back a persistent URL that contains the diff with workflow, comments, search, etc. Basically some of the helpful features that Github offers on PR diffs, just available for any arbitrary diff. I wrote this tool to use at work for documenting snapshot diff triaging, and also used it to help with the same thing on a couple Ty PRs. Example: https://diffswarm.dev/d-01k2gknwyq82f6x17zqf3apjxc
- DODiffs of Word documents, designed for humans2013 · ▲69
We're building version control software for Microsoft Office documents that works as well as Git and GitHub do for code. Today, we’re releasing the first component, Draftable for Word, an Office add-in that lets you generate side-by-side diffs, and makes it way less painful to work with Track Changes. Our diffs are designed to look right to humans — instead of machines — showing changes as they might actually have been made by an editor. We'd love to hear your feedback. We’d also love to fix what you find painful about authoring and collaborating on Microsoft Office documents, so get in…
