rneovim.git/runtime/lua/vim/func, branch fix_20726 Neovim fork with Rahm's personal hacks. feat(lua): add vim.func._memoize 2023-09-20T12:42:41+00:00 Lewis Russell lewis6991@gmail.com 2023-09-16T22:10:30+00:00 877d04d0fb83b5fc602dbab22b58f26a793ec236 Memoizes a function, using a custom function to hash the arguments. Private for now until: - There are other places in the codebase that could benefit from this (e.g. LSP), but might require other changes to accommodate. - Invalidation of the cache needs to be controllable. Using weak tables is an acceptable invalidation policy, but it shouldn't be the only one. - I don't think the story around `hash_fn` is completely thought out. We may be able to have a good default hash_fn by hashing each argument, so basically a better 'concat'.
