Generating dot graphs

In larger workspaces it’s often hard to understand the dependency structure. With bake you can generate a dot file (see http://www.graphviz.org):

bake ... --dot [<dot filename>]

If filename is omitted, a file <main config name>.dot in main project dir is created. The dot file is a text file with all dependencies included. It is easy to render an image, e.g. with

tred <dot filename> | dot -Tpng -o <png image filename>
../../_images/dot.png

  • Projects are rectangles

  • Configs are ellipses

  • CustomConfigs are red

  • ExecutableConfigs are green

  • LibraryConfigs are cyan

It’s possible to generate only a part of the whole graph with -p (same as for building only a part of the code). e.g.:

bake ... --dot <dot filename> -p lib2
bake ... --dot <dot filename> -p lib2,testa

Which results in:

../../_images/dotP.png ../../_images/dotPC.png

With –dot-project-level the depenencies are written on project level, not on config level.
