## 项目历史与用法

dwdiff is G. P. Halkes' word-level diff utility. The official page positions it against wdiff: mostly command-line compatible, but with user-defined whitespace and delimiter handling so punctuation or other single characters can be treated as words.

### 项目历史

The official copyright notice covers 2006-2018 and 2020, and the official distribution directory carries 1.0 release artifacts. Later 2.1.x news entries show maintenance releases in 2018 and 2020 for ICU/pkg-config and compiler compatibility rather than feature expansion.

### 采用历史

The official download section says several Linux distributions and BSDs shipped packages or ports, naming Fedora, FreeBSD, and OpenBSD, with additional Unix packaging through Sunfreeware, MacPorts, Homebrew, Slackbuilds.org, Slacky.eu, and OpenPKG. The batch input adds Debian, Ubuntu, Nix, MacPorts, and Homebrew entries.

### 使用方式

dwdiff compares text at word granularity and prints the new text annotated with insertion and deletion markers by default. It is useful when line diffs are too coarse, especially prose, documentation, localization, and wrapped text where changed words matter more than changed lines.

### 为什么软件包爱好者会关心

dwdiff matters because it is a classic small Unix text-processing tool that fills the gap between line-oriented diff and heavier document comparison. Its compatibility with wdiff plus delimiter controls made it packageable as a drop-in word-diff option across many Unix packaging systems.

### 时间线

- 2006: Official copyright range begins and 1.0 release artifacts are present in the official distribution directory.
- 2018: Version 2.1.2 updates ICU handling and replaces icu-config with pkg-config.
- 2020: Versions 2.1.3 and 2.1.4 fix GCC 10 and C99 compiler build issues.

### Related projects

- The official page explicitly compares dwdiff with wdiff. In the broader CLI ecosystem it complements diff, git diff --word-diff, colordiff, and document-oriented compare tools.
