Expose snippet reload function, enables integration with plugins like nvim-scissors

[chrisgrieser]

I am the maintainer of nvim-scissors, and would like to implement a hot-reload-support for blink.cmp. To be able to do that, blink.cmp needs to expose some sort of function that reloads a snippet file inside providers → 'blink.cmp.sources.path' → opts.searchpaths..

snippet engines usually expose such functionality, so other plugins can properly integrate with them, e.g. require("luasnip.loaders").reload_file(path) for luasnip: /~https://github.com/L3MON4D3/LuaSnip/blob/master/DOC.md#loaders

It would be great for blink.cmp to also expose such a function.

It looks like the way snippets are loaded makes it pretty tricky to do this cleanly, but it's currently possible to bust the cache in a highly undocumented way:

local reset_snippets_cache = function()
    local snippets_provider = vim.iter(require("blink.cmp").sources.providers):find(function(provider)
        return provider.name == "Snippets"
    end)
    if not snippets_provider then
        return
    end
    -- could theoretically scope this to a filetype, but not much point
    snippets_provider.module.cache = {}
end

I could imagine exposing a reset() method, but I'm not sure if it would see much use beyond this specific case. Happy to put in a PR if there's agreement on an approach.

require('blink.cmp').sources.reload() should do the trick. This API may change in the future but I'll send a message your way if it does

Thank you!

Unfortunately, it appears the reload function is not working. require('blink.cmp').sources.reload() does not reload the snippets if there are changes. There is also no error of any kind, it just silently does nothing. (using v0.4.1)

Sorry about that, it got broken during the sources rework. Fixed in 407f2d5
