## プロジェクトの歴史と使われ方
diffstat reads diff output and produces per-file histograms of insertions, deletions, and modifications. It is a compact review aid for large patch sets.
### プロジェクトの歴史
Thomas E. Dickey's official history says he originally wrote diffstat in 1992, alongside rcshist, to trace changes in collections of files. He later found it most useful for summarizing source patches.
### 採用の歴史
The official history says broader attention arrived in early 1996 when developers on XFree86 and ncurses mailing lists started using it. It also notes Linux kernel patch-process visibility through BitKeeper-era workflows and Git's later built-in ability to generate diffstat-style summaries.
### 使われ方
diffstat sits after `diff` in a pipeline and turns patch text into a size-and-shape summary. That makes it useful in email review, release notes, package deltas, and quick scans of large changes before reading detailed hunks.
### パッケージ好きにとっての重要性
Package maintainers care about diffstat because it is one of the small classic tools that made patch exchange readable at scale. The output compresses a patch into a reviewable map: which files changed and roughly how much.
### タイムライン
- 1992: Thomas E. Dickey wrote diffstat.
- 1996: XFree86 and ncurses developers began using it more visibly.
- 2002: Linux kernel BitKeeper patch workflow documentation referenced diffstat-style summaries.
- 2026: diffstat 1.69 released with compiler-warning fixes.
### Related projects
- diffstat depends culturally and practically on diff and patch workflows; Git later incorporated diffstat-style output for repository changes.
