When using LuaSnip together with nvim-cmp and a snippet library like friendly-snippets or luasnip-snippets you get a lot of duplicated snippets. That’s because the language server also servers snippets. Also, you might want to create your own custom snippet that happens to share the name of a snippet that already exists.

For example, with the setup mention above, let’s say that I also have a custom fn snippet for Rust files. When I type fn, nvim-cmp suggests three snippets: one from rust-analyzer, one from friendly-snippets and my custom one.

The solution to overriding friendly-snippets with your custom ones suggested in this open LuaSnip issue is to create your own fork of friendly-snippets. However, this is not ideal because it adds a lot of extra work to each user to ensure that their fork is up-to-date with upstream. Also, it doesn’t solve the issue with language servers serving snippets with the same name. I know that for most language servers you can disable snippets, but that doesn’t really solve the issue either because you might want some of those snippets.

What I would like is the option to only see one of the snippets listed if there are multiple ones with the same name. Which one would be controlled with a priority list, for example:

1. If there’s a custom user snippet, use that
2. Otherwise, if there’s an LSP snippet, use that
3. Otherwise, use the one from friendly-snippets

Is this possible to achieve today?
