How can I find the location where a snippet is coming from?

[westernwontons]

I'm inside a Rust project, and I get these 'Relm4' related snippets and I can't find where they're coming from.

I'm very sure I haven't defined them anywhere, I don't have the package dowloaded anywhere. I don't understand where they might be defined.

I did manage to remove them by having the following in my nvim-cmp config:

      {
        name = "luasnip",
        priority = 4,
        entry_filter = function(entry, _)
          if string.match(entry.completion_item.label, "^relm%-") then return false end
          return true
        end,
      },

but I shouldn't be having these snippets appear in the first place

Oh, you should be able to find the location via snip_location, as long as they're loaded by a loader.
If snip_location can't find it, the snippet is coming from lsp, and you probably can't do better than using some filter

I gave it a go with jump_to_active_snippet but it says the snippet is not associated with a loader. What's even more annoying that for example with Rust I have a snippet named "pfn", but the LSP also has one, and no matter what priority I set for mine, it's still not the first match. Is there a way to get around this?

The help is much appreciated!

Hm, yeah okay, then it's provided by LSP (I'm assuming you did set the ls.setup-variable which adds the source?)
It's possible to filter out specific results from lsp by intercepting the default callback (I've got something like that set up here, but it isn't 100% your usecase, so you'd have to tinker with that a bit)

Thanks for that snippet of code! Although, in the end I've found the problem. I'm using AstroNvim which provides friendly-snippets and those relm related snippets and actually a bunch of others that I did not want we're coming from there. Disabling friendly-snippets solved the issue. Thanks for the help, I don't think I would've found their source if not for you!

Ah nice, glad I could help :D

Just bumped into this issue as well. These snippets come from the frameworks directory in friendly-snippets, which probably (at least the friendly-snippets README.md suggests so) shouldn't be loaded by default in LuaSnip.

I tried

require("luasnip.loaders.from_vscode").lazy_load({ exclude = { "frameworks" } })

but it doesn't do anything. And I can't figure out in which repo the problem is and if there is a solution :)
