I have written a little program called CodeTwig. It may be of interest to Nim-programmers who sometimes loose oversight of their code. :-)
CodeTwig is terminal-program to view the outline of the source-code and to show procedures as usage-trees or used-by-trees. <https://github.com/some-avail/codetwig> As Nim-programmer you are supposed to compile it yourself. I have only tested it on linux, but I have only used cross-platform functions . However maybe line-endings are problemetic, but i dont expect that. Limitations (currently): * no sub-dirs are suported yet. * for now only single-project-views.
