Blink.cmp Doesn’t Recognize LuaSnip Snippets Starting with “;” or “.”

[odlove]

Hello, I’m new to blink.cmp and loading custom snippets via LuaSnip, but a few snippets that begin with “;” or “.” work fine in nvim-cmp yet aren’t recognized by blink.cmp.
with blink.cmp:

with nvim-cmp:

Other snippets appear to function correctly.

And here’s my blink.cmp configuration.

{
      'saghen/blink.cmp',
      -- optional: provides snippets for the snippet source
      dependencies = { 'rafamadriz/friendly-snippets' },

      -- use a release tag to download pre-built binaries
      version = '1.*',
      -- AND/OR build from source, requires nightly: https://rust-lang.github.io/rustup/concepts/channels.html#working-with-nightly-rust
      -- build = 'cargo build --release',
      -- If you use nix, you can build from source using latest nightly rust with:
      -- build = 'nix run .#build-plugin',

      ---@module 'blink.cmp'
      ---@type blink.cmp.Config
      opts = {
          -- 'default' (recommended) for mappings similar to built-in completions (C-y to accept)
          -- 'super-tab' for mappings similar to vscode (tab to accept)
          -- 'enter' for enter to accept
          -- 'none' for no mappings
          --
          -- All presets have the following mappings:
          -- C-space: Open menu or open docs if already open
          -- C-n/C-p or Up/Down: Select next/previous item
          -- C-e: Hide menu
          -- C-k: Toggle signature help (if signature.enabled = true)
          --
          -- See :h blink-cmp-config-keymap for defining your own keymap
          keymap = {

          completion = { documentation = { auto_show = false } },

          -- Default list of enabled providers defined so that you can extend it
          -- elsewhere in your config, without redefining it, due to `opts_extend`
          sources = {
              default = { 'lsp', 'path', 'snippets', 'buffer' },
          },

          snippets = { preset = 'luasnip' },


          -- (Default) Rust fuzzy matcher for typo resistance and significantly better performance
          -- You may use a lua implementation instead by using `implementation = "lua"` or fallback to the lua implementation,
          -- when the Rust fuzzy matcher is not available, by using `implementation = "prefer_rust"`
          --
          -- See the fuzzy documentation for more information
          fuzzy = { implementation = "prefer_rust_with_warning" }
      },
      opts_extend = { "sources.default" }
  }

Hey! The documentation isn't super clear about this, so we’ll probably add a note.

You want to trigger the completion menu with special characters. Some sources have default "trigger" characters, while others (like luasnip) don't. But what's cool is that you can customize it for each source.

Here’s how you can do it for your use case:

sources = {
  default = { ... },

  -- add this
  providers = {
    snippets = {
      override = {
        get_trigger_characters = function(_) return {';', '.'} end,
      },
    },
  },
},
