PR Diff Filter

Hide GitHub pull request files by regex, and auto-mark them as Viewed.

PR Diff Filter hides files in a GitHub pull request's Files Changed (or Changes) tab based on regex patterns you control — generated code, lockfiles, snapshots, vendored files, whatever clutters your review — and can optionally auto-mark those files as Viewed so they collapse out of your way. Why: - Large PRs bury the files that actually need a human look under generated/vendored noise. - GitHub's own file filter is manual and per-session; this remembers your rules across every PR you open. Features: - One regex pattern per line, tested against the repo-relative file path (e.g. src/foo/bar.spec.ts). - Live "Test a path" box in the options page shows which rule matches. - Hide or collapse mode for filtered files. - Optional auto-mark as Viewed for matched files (clicks GitHub's own Viewed toggle — see Privacy Policy). - Adjusts the PR's "+N -N" line-change header to reflect only what you're actually reviewing, with the true total always one hover away. - Works with GitHub's newer virtualized diff view and the consolidated /changes route. - Everything runs locally in your browser. No account, no external server, no data collection. Open source: https://github.com/lfsevergnini/pr-diff-filter
