cxx2flow

将 C/C++ 代码转换为流程图

安装

bash cargo install cxx2flow

使用

为了编译生成的 dot 文件，你需要安装 graphviz，并将其添加到 PATH 中。也可以将生成的结果复制进在线的 graphviz 服务中，如 http://viz-js.com/ 。

``` bash cxx2flow --help cxx2flow 0.1.0 mgt. mgt@oi-wiki.org Convert your C/C++ code to control flow graph

USAGE: cxx2flow [OPTIONS] [FUNCTION]

FLAGS: -h, --help Prints help information -V, --version Prints version information

OPTIONS: -o, --output

Sets the output file. If not specified, result will be directed to stdout. e.g. graph.dot

ARGS: Sets the input file. e.g. test.cpp The function you want to convert. e.g. main

Note that you need to manually compile the dot file using graphviz to get SVG or PNG files. EXAMPLES: cxx2flow test.cpp | dot -Tpng -o test.png cxx2flow main.cpp mycustomfunc | dot -Tsvg -o test.svg ```
