Roadmap: Git Diff Viewer

[erdembas]

Git Diff Viewer

Priority: Medium-High | Effort: Medium | From: ROADMAP.md

See what changed without opening an editor or running git diff in a terminal.

Scope

• Inline Diff View — Click dirty file count to open diff viewer with changed files
• Syntax Highlighting — Language-aware highlighting (JS/TS, Rust, Python, Go, YAML, JSON)
• View Modes — Side-by-side (split) and unified (inline) toggle
• Quick Commit — Stage files, write commit message, and push from the diff viewer
• Cross-Project Uncommitted Changes — All uncommitted changes across all projects in one view
• Branch Comparison — Diff between any two branches without checking out

Technical Notes

• Extend runhq-core/src/git.rs with git diff / git diff --staged parsing
• Syntax highlighting: tree-sitter / syntect (Rust) or highlight.js (frontend)

Why

git diff in a terminal is functional but hard to read. Opening VS Code just to see a diff is overkill. An inline viewer gives you the information at a glance.
