This repository contains two scripts for refactoring coq code, using .glob files generated by Dune.
The first script, generate.py searches a directory and its subdirectories for definitions, lemmas and proofs that need to be converted to snake_case. This can of course be adapted to your own use case. It takes 3 (optional) arguments: the search directory, the project root and the "glob root", for example:
$ ./generate.py ./generate.py UniMath/CategoryTheory/Limits/ ../coq/This searches the directory ../coq/UniMath/CategoryTheroy/Limits for definitions that still need updating. The default argument for the glob root is _build/default, so the script will look for the corresponding glob files in ../coq/_build/default/UniMath/CategoryTheory/Limits/. If your glob files are located elsewhere (for example, next to your files or in another directory), you need to supply their root directory as a third argument.
generate.py generates a file called changes.txt. Every line in this file lists the namespace of an identifier that needs changing, its new name and its old name. Of course, this file can also be generated manually. A line in this file looks like:
UniMath.CategoryTheory.Limits.Cats.Limits postcomp_with_lim_arrow postcompWithLimArrow
The second script, substitute.py takes the substitutions listed in changes.txt and applies them to all files in a directory (and its subdirectories). Its arguments are very similar to those of generate.py:
$ ./substitute.py UniMath ../coq/This will perform all the substitutions listed in changes.txt in all files under ../coq/UniMath/ (again, using _build/default as the glob root).
