plugin idea: cyclomatic complexity somewhere near the functionname in the symbol list.

Hello everyone.

I found and have grown fond of a particular metric. cyclomatic complexity (wikipedia link) To save you the "definition jargon", it counts your ifs, while, blocks, etc. in a function. Meaning, even a short, but a highly nested function is 'bad' and a long function can be considered 'good' if only it's not very complex and mostly linear / sequential.

I use it in python with this module: https://radon.readthedocs.io/en/latest/intro.html#cyclomatic-complexity

Which takes a python file and returns a sorted list of the functions in that file, with color coding and the worst being at the top.

For my case I can just set it up as a custom command.

But I still need to remember to press the button. It would be a quality of life improvement if the command ran automatically, let's say every time I save a file and if the feedback I'm getting wouldn't come as text output in the built in console, but as some kind of colored hint in the symbol list. E.g. maybe a colored [CC:A] or [CC:F].

Since it's a general metric, it may be interesting to set this up for other languages as well.

You can do this with a plugin that runs at save and displays the data in a separate sidebar. Such a plugin could support a number of languages.
