LuaSnip Source Cache Is Not Cleared When Snippets Are Updated

Make sure you have done the following

• I have updated to the latest version of blink.cmp
• I have read the README

Bug Description

Currently, when LuaSnippets are added or modified in their respective files, the internal cache of the luasnip source is not automatically cleared. This necessitates either a manual call to the API's reload function or a full Neovim restart to reflect the updated snippets. This behavior disrupts workflow and reduces usability.

LuaSnip provides the following events:

• LuasnipSnippetsAdded: Triggered when snippets are added or modified.
• LuasnipCleanup: Triggered when all snippets need to be cleared.

However, the cache is not automatically refreshed upon emitting these events, which prevents users from seeing updated snippets.

While related issues (#603 and #615) have discussed this problem, the existing fix still requires manual intervention or a restart, which does not fully resolve the issue.

I have addressed this issue in my fork. If you're interested, I can submit a PR with the fix.

Relevant configuration

{
  'saghen/blink.cmp',
  version = 'v0.*',
  -- !Important! Make sure you're using the latest release of LuaSnip
  -- `main` does not work at the moment
  dependencies = { 'L3MON4D3/LuaSnip', version = 'v2.*' },
  opts = {
    snippets = {
      expand = function(snippet) require('luasnip').lsp_expand(snippet) end,
      active = function(filter)
        if filter and filter.direction then
          return require('luasnip').jumpable(filter.direction)
        end
        return require('luasnip').in_snippet()
      end,
      jump = function(direction) require('luasnip').jump(direction) end,
    },
    sources = {
      default = { 'lsp', 'path', 'luasnip', 'buffer' },
    },
  }
}
