## 项目历史与用法

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.

### 项目历史

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.

### 采用历史

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.

### 使用方式

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.

### 为什么软件包爱好者会关心

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.

### 时间线

- 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.
