Documentation

cxx2flow

将 C/C++ 代码转换为流程图

效果

更多效果图请参考 GALLERY

两种样式:

折线 平滑
ployline curve
inline int read() {  //快读
  char c = getchar();
  int x = 0, f = 1;
  while (c < '0' || c > '9') {
    if (c == '-') f = -1;
    c = getchar();
  }
  while (c >= '0' && c <= '9') {
    x = x * 10 + c - '0';
    c = getchar();
  }
  return x * f;
}

安装

自行编译

cargo install cxx2flow

下载预构建二进制

可以到 GitHub ActionsNightly.link 下载最新构建的二进制,包含 Linux 和 Windows 版本。

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://magjac.com/graphviz-visual-editor/

mgt <mgt@oi-wiki.org>
Convert your C/C++ code to control flow chart

USAGE:
    cxx2flow [OPTIONS] <INPUT> [FUNCTION]

ARGS:
    <INPUT>       Sets the input file. e.g. test.cpp
    <FUNCTION>    The function you want to convert. e.g. main [default: main]

OPTIONS:
    -c, --curly              Sets the style of the flow chart.
                             If specified, output flow chart will have curly connection line.
    -h, --help               Print help information
    -o, --output <OUTPUT>    Sets the output file.
                             If not specified, result will be directed to stdout.
                             e.g. graph.dot
    -t, --tikz               Use tikz backend.
    -V, --version            Print version information

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 my_custom_func | dot -Tsvg -o test.svg

限制

  • 不支持预处理器,如 include, ifdef, ifndef...
  • 支持的控制流语句有:while,for,if,break,continue,break,return,switch, goto, do-while。
