## 项目历史与用法
grap is an implementation of the Bell Labs grap language for typesetting graphs in troff, groff, TeX, and other document-formatting pipelines that can consume pic output.
### 项目历史
The grap language was specified and first implemented by Brian Kernighan and Jon Bentley at Bell Labs. Ted Faber's implementation was written because groff did not include a free grap implementation, and the repository describes it as an implementation of Kernighan and Bentley's language.
The project preserves a classic Unix documentation workflow: a small language is processed into pic, then included in typeset documents. That lineage places grap beside troff preprocessors such as pic, tbl, and eqn.
### 采用历史
grap is niche but durable because it solves a specific documentation problem for users who still value text-based, reproducible graph descriptions inside Unix typesetting systems. It appears in package managers for people maintaining historical troff/groff workflows or converting old documents.
### 使用方式
Users write graph descriptions in grap, run the preprocessor to generate pic, and let pic/troff, groff, or TeX-oriented workflows render the graph in a document.
### 为什么软件包爱好者会关心
grap matters to package nerds because it is a preservation-friendly Unix tool: tiny, source-buildable, text-oriented, and useful mainly when the rest of a document toolchain is installed correctly.
### 时间线
- 1986: Bentley and Kernighan published GRAP, a language for typesetting graphs, in Communications of the ACM.
- 1998-2009: Ted Faber copyright range shown in the repository README.
- 2025-04-16: Lunabase project page listed version 1.49.
### Related projects
- pic is the immediate output language and troff/groff are the common formatting environments.
- TeX can participate through workflows that consume pic-generated output.
- The original Bell Labs language is the historical source for Ted Faber's implementation.
