调研方向

使用 test.lua 示例和 Neovim 重现该问题，重点关注类型为 my_type|my_type[] 的参数的补全编辑范围。跟踪参数位于花括号内时补全范围的计算方式。完成的标准是：选择补全项时仅替换花括号内的值，并保留周围的列表语法。

What is the issue affecting?

Completion

Expected Behaviour

For parameters that can either be a single value or a list T|T[], when already in a table, the completion range should not include surrounding curly braces.

Actual Behaviour

The completion edit range provided by lua-language-server for parameters seems to always include the entire parameter, which causes issues when completing params that can be either a single value or a list, for example, T|T[].

Reproduction steps
  1. Create test.lua in the test dir with the following content: 
    ---@alias my_type 'a'|'b'

---@param arg my_type|my_type[]
local function test_func(arg)
  return arg
end
  2. Use neovim to edit test.lua
  3. Try to call test_func at the end of the file with a list parameter: test_func({ ... })
  4. Completions provided by lua-language-server are shown inside the curly braces
  5. Selecting one of the completions replaces the whole parameter, including the surrounding curly braces.

Additional Notes

I have also reported to the blink.cmp but the maintainer thinks that it is a lua-language-server's issue: https://github.com/Saghen/blink.cmp/issues/2179
