Introduction

非常棒的学习对象，学习构建一个自己的工具。不少常见应用（confluence, doxygen, sphinx 等）都通过插件的方式用上它。

  1. 提供 python 接口，可以快速构图
  2. 提供 cmd line，包括 dot 等多个 binary
  3. 提供插件，给 confluence，doxygen 等提供服务
  4. 定义了 dot 语言

Example

  1. 生成 dot 文件 cmake --graphviz=dot_file_prefix .. 每个目标都会生成一个 dot 文件
  2. 将 dot 文件转成图片， dot -Tsvg graph_sublas.dot.gtest_trsv > graph_trsv.svg

summary

学习 graphviz 来制作一个属于自己的工具。

todo

cmake 是如何集成 graphviz 的，graphviz 是如何让 cmake 集成的。
