Install

Compile yourself

cargo install cxx2flow

Download pre-built binaries

It is recommended to download the binary file of the corresponding platform from Github Release on the right.

You can also go to GitHub Actions or Nightly.link to download the latest built binaries, including Linux, Windows and MacOS versions.

Use GUI version

For users who have no command line experience, it is recommended to download and use the GUI version written based on tauri. https://github.com/Enter-tainer/cxx2flow-gui/releases

use

In order to compile the generated dot files, you need to install graphviz and add it to your PATH. You can also copy the generated results into the online graphviz service, such as http://magjac.com/graphviz-visual-editor/.

 Convert your C/C++ code to control flow chart

Usage: cxx2flow [OPTIONS] [INPUT] [FUNCTION]

Arguments:
  [INPUT]     Sets the path of the input file. e.g. test.cpp
              If not specified, cxx2flow will read from stdin.
  [FUNCTION]  The function you want to convert. e.g. main [default: main]

Options:
  -o, --output <OUTPUT>  Sets the output file.
                         If not specified, result will be directed to stdout.
                         e.g. graph.dot
  -c, --curly            Sets the style of the flow chart.
                         If specified, output flow chart will have curly connection line.
      --cpp              Use C preprocessor.
  -t, --tikz             Use tikz backend.
  -d, --dump-ast         Dump AST(For debug purpose only).
  -h, --help             Print help information
  -V, --version          Print version information

Note that you need to manually compile the dot file using graphviz to get SVG or PNG files.

EXAMPLES:
    cat main.cpp | cxx2flow | dot -Tsvg -o test.svg
    cxx2flow test.cpp | dot -Tpng -o test.png
    cxx2flow main.cpp my_custom_func | dot -Tsvg -o test.svg

limit

• Support for preprocessors is based on cpp , which is turned off by default and needs to be enabled manually using the --cpp parameter. Will fail if cpp does not exist in PATH .
• The supported control flow statements are: while, for, if, break, continue, break, return, switch, goto, do-while.
• There is basic support for range for. In some cases, due to tree-sitter-cpp capacity limitations, some problems may occur.
