CodeDependencyVisualizer

This tool is intended for reverse engineering UML class diagrams out of existing C++ code. It can generate class diagrams with inheritances and associations.

Dependencies

python 2.7
clang version 3.5
graphvitz (for the dot tool) to be able to transform the generated dot file to an image

Just tested on Linux.

Usage

For usage information run: python ./CodeDependencyVisualizer.py --help

usage: CodeDependencyVisualizer.py [-h] -d D [-o OUTFILE]
                                   [-u WITHUNUSEDHEADERS] [-a] [-i] [-p] [-t]
                                   [-P] [-I INCLUDEDIRS [INCLUDEDIRS ...]]
                                   [-v]

CodeDependencyVisualizer (CDV)

optional arguments:
  -h, --help            show this help message and exit
  -d D                  directory with source files to parse (searches
                        recusively)
  -o OUTFILE, --outFile OUTFILE
                        output file name / name of generated dot file
  -u WITHUNUSEDHEADERS, --withUnusedHeaders WITHUNUSEDHEADERS
                        parse unused header files (slow)
  -a, --associations    draw class member assiciations
  -i, --inheritances    draw class inheritances
  -p, --privMembers     show private members
  -t, --protMembers     show protected members
  -P, --pubMembers      show public members
  -I INCLUDEDIRS [INCLUDEDIRS ...], --includeDirs INCLUDEDIRS [INCLUDEDIRS ...]
                        additional search path(s) for include files (seperated
                        by space)
  -v, --verbose         print verbose information for debugging purposes
  --exclude_classes EXCLUDE_CLASSES
                        classes matching this pattern will be excluded
  --include_classes INCLUDE_CLASSES
                        only classes matching this pattern will be included

Examples

./CodeDependencyVisualizer.py -aiptP --verbose -d dummyCppProject -I dummyCppProject/subfolder"

The command above just creates the file 'uml.dot'. To convert the dot file to an svg image run the dot tool:

dot -T svg -o uml.svg uml.dot
