Can't seem to make completion that involves comment prefixes to work

[justinluque]

Hello!

I'm using this plugin in combination with luasnip and friendly-snippets to add snippets to my workflow. Friendly-snippets provides documentation snippets which must be enabled by the user to access in config, which I've done. I know they're enabled correctly because I can use the snippets from that file that begin with things like "@param" and "@return". However I can't seem to get snippets with the prefixes "/*" and "/**" to work right. Has anyone else had this problem? Here's my config:

return {
  "saghen/blink.cmp",

  dependencies = {
    { "L3MON4D3/LuaSnip", version = "v2.*" },
  },

  opts = {
    snippets = {
      preset = "luasnip",
    },
  },

  sources = {
    default = { "snippets", "lsp", "path", "buffer" },
  },
}

return {
  "L3MON4D3/LuaSnip",

  dependencies = {
    "rafamadriz/friendly-snippets",
  },
  config = function(_, opts)
    if opts then
      require("luasnip").config.setup(opts)
    end
    vim.tbl_map(function(type)
      require("luasnip.loaders.from_" .. type).lazy_load()
    end, { "vscode", "snipmate", "lua" })
    -- friendly-snippets - enable standardized comments snippets
    require("luasnip").filetype_extend("lua", { "luadoc" })
    require("luasnip").filetype_extend("python", { "pydoc" })
    require("luasnip").filetype_extend("rust", { "rustdoc" })
    require("luasnip").filetype_extend("cs", { "csharpdoc" })
    require("luasnip").filetype_extend("java", { "javadoc" })
    require("luasnip").filetype_extend("c", { "cdoc" })
    require("luasnip").filetype_extend("cpp", { "cppdoc" })
    require("luasnip").filetype_extend("sh", { "shelldoc" })
  end,
}

cdoc.json

This is because your snippet have only special characters, namely /, and *. See this related issue: #1688

In the meantime you could workaround this with the following config, this will trigger snippet source (so in your case luasnip) whenever your type *:

sources = {
  -- ...
  providers = {
    snippets = {
      override = {
        get_trigger_characters = function(_) return {'*'} end,
      },
    },
  },
},
