yFlowGen

Flow chart (gml or dot+svg file format) is automatically generated by inputting C language (C, C ++) source file to yFlowGen.exe.
In addition to the execution method at the command prompt, a method to execute it with the GUI is also available separately.

The file format can be selected from "GML file" or "DOT file + SVG file".

• For GML files, you need to install yEd Graph Editor to display and arrange them. [https://www.yworks.com/products/yed/download#download]
• For DOT+SVG files, Graphviz installation is required to convert DOT to SVG files. [https://graphviz.org/download/]

Example : For GML files

Execute the following command at the windows command prompt. In the example, specify sample.c as the source file.

yFlowGen.exe -f sample.c  

Example : For DOT + SVG files

Execute the following command at the windows command prompt. In the example, specify sample.c as the source file. In the case of DOT+SVG files, automatic alignment is also performed by the function of Graphviz.

yFlowGen.exe -f sample.c -format dot
