One of the beautiful things about Sublime Merge¹ (and git/diffs) is that you can see exactly what has changed in complex expected values in tests to ensure that you’re updating the tests without overlooking regressions.

(This is from the Markdown page loader tests in Kitten², as I’m refactoring to implement the upcoming breaking change in the stateful components API³ as it affects the generated code for stateful layout components in Markdown pages.)

¹ Which I always have running, full-screen on its own monitor.
² https://kitten.small-web.org
³ Currently experimental and undocumented but that should change once this breaking change is implemented.

“Difftastic — my new favourite diff viewer”

#git #diff

The new Claude Desktop app includes a new diff viewer. I compared three ways to review Claude's code changes: the Desktop app diff viewer, the Claude Code CLI, and plain git diff, with a note on when to reach for each one.

gvc (git-visual-compare) is a new visual git diff tool that I'm releasing today! Try it out at: https://dafoster.net/projects/gvc/ #coding #programming #diff #git

I've been using the diff mode of the venerable yet unmaintained GitX tool for a decade. But now I need my diffs to support dark mode, to avoid waking the baby at night. Astonishingly, existing GUI diff tools only support diffing *individual* commits, not ranges . So I finally bit the bullet and wrote my own. Enjoy!

“Most writing is about getting words down in a structure that makes sense, and then getting those words in front of other people. #Markdown does that with less #friction than anything else ever created. You can learn it in ten minutes, write it in any text editor on any device, read the source file without rendering it, diff it in version control, and convert it to virtually any output format.”

[diffnav - GitHub 스타일의 Git diff pager

Delta의 렌더링 기능을 기반으로 GitHub의 파일 트리 UI를 터미널 환경에서 재현한 TUI 도구인 Diffnav가 발표되었습니다. Go 언어와 Bubble Tea 프레임워크로 구현되어 맥, 리눅스, 윈도우를 지원하며, 사이드바 파일 트리를 통해 변경된 파일 간 빠르게 이동할 수 있습니다. 양쪽 비교 및 통합 보기 전환, 파일 상태별 색상 표시 및 아이콘 스타일 커스터마이징, 설정 파일 통한 UI 조정 등이 가능하며, GitHub CLI와 함께 사용 시 PR diff 탐색에 적합합니다.
