history
Project history and usage
diffr is a terminal filter that refines unified diffs with word-level highlighting, making code review easier when ordinary line-oriented output is too coarse.
Project history
The changelog records the initial 0.1.0 release on 2019-07-01. Early releases added color customization, split reusable logic into `diffr-lib`, optimized LCS post-processing, and added line-number display.
Adoption history
The official README documents installation through Homebrew, Arch AUR, Cargo, and direct source builds. It also shows diffr configured as a Git pager and interactive diff filter, which is the main adoption path for daily review use.
How it is used
diffr reads unified diff input on stdin and writes enhanced output on stdout. The README shows `git show HEAD | diffr` for one-off use and `.gitconfig` settings that route Git paging and interactive diffs through diffr.
Why package nerds care
diffr matters to package and source maintainers because it stays in the Unix-filter tradition: no repository database, no review server, just a small CLI that improves the diffs developers already pipe around.
Timeline
- 2019: 0.1.0 initial release.
- 2019: 0.1.2 split reusable logic into diffr-lib.
- 2020: 0.1.3 added line-number display.
Related projects
- The README calls diffr an improvement on Git's diff-highlight script and notes Git's built-in `--word-diff` and `--color-words` options as related approaches.
