Snippets Go to default configuration

Blink uses the vim.snippet API by default for expanding and navigating snippets. The built-in snippets source will load friendly-snippets, if available, and load any snippets found at ~/.config/nvim/snippets/. For use with Luasnip, see the Luasnip section.

Custom snippets

By default, the snippets source will check ~/.config/nvim/snippets for your custom snippets, but you may add additional folders via sources.providers.snippets.opts.search_paths. Currently, only VSCode style snippets are supported, but you may look into Luasnip if you'd like more advanced functionality.

Chris Grieser has made a great introduction to writing custom snippets in the nvim-scissors repo. Here's an example, using the linux/mac path for the neovim configuration:

// ~/.config/nvim/snippets/package.json
{
  "name": "personal-snippets",
  "contributes": {
    "snippets": [
      { "language": "lua", "path": "./lua.json" }
    ]
  }
}

// ~/.config/nvim/snippets/lua.json
{
  "foo": {
    "prefix": "foo",
    "body": [
      "local ${1:foo} = ${2:bar}",
      "return ${3:baz}"
    ],
  }
}

Luasnip

{
  'saghen/blink.cmp',
  version = '*',
  -- !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' },
    },
  }
}

Disable all snippets

sources.providers.transform_items = function(_, items)
  return vim.tbl_filter(function(item)
    return item.kind ~= require('blink.cmp.types').CompletionItemKind.Snippet
  end, items)
end

When setting up your capabilities with lspconfig, add the following:

capabilities = require('blink.cmp').get_lsp_capabilities({
  textDocument = { completion = { completionItem = { snippetSupport = false } } },
})

Some LSPs may ignore the snippetSupport field, in which case, you need to set LSP specific options while setting them up. Some examples:

-- If you're using `opts = { ['rust-analyzer'] = { } }` in your lspconfig configuration, simply put these options in there instead

-- For `rust-analyzer`
lspconfig['rust-analyzer'].setup({
  completion = {
    capable = {
      snippets = 'add_parenthesis'
    }
  }
})

-- For `lua_ls`
lspconfig.lua_ls.setup({
  settings = {
    Lua = {
      completion = {
        callSnippet = 'Disable',
        keywordSnippet = 'Disable',
      }
    }
  }
})

Please open a PR if you know of any other LSPs that require special configuration!
