You reminded me of the time I solved a thorny PROGRESS/4GL programming problem in the 80's using PC-Write (what an editor that was!) by writing a macro file containing a code-gen/-mod script, and then feeding the macro file into PC-Write and processing 2,000 source files in a few minutes, ready for re-compilation. I haven't done that too much with vim in the ~35 years since then, but that's only because I haven't quite grok'ed how to write vim macro's by hand, yet. I should probably figure that out by now, but as a vim guy all I've ever needed is maybe 1% of all of vim's feature set to be productive ..
