New Formatter

[CppCXY]

The current formatter is not directly integrated into emmylua_ls for use. It is currently distributed as a binary, and you can use it by configuring it as an external tool.

The current version is still quite rudimentary. After receiving sufficient feedback, I will continue improving the formatter and officially release it in the May 1st version, integrating it into emmylua_ls as the default formatter.

Download cli from https://github.com/EmmyLuaLs/emmylua-analyzer-rust/actions/runs/23744280571
config in .emmyrc.json:

{
  "format": {
    "externalTool": {
      "program": "path/to/luafmt",
      "args": [
        "--stdin"
      ]
    }
  }
}

config style in .luafmt.toml:

[layout]
max_line_width = 100
table_expand = "Auto"
call_args_expand = "Auto"
func_params_expand = "Auto"

[output]
quote_style = "Preserve"
trailing_table_separator = "Multiline"
single_arg_call_parens = "Preserve"

@lewis6991 @xuhuanzy @clason any suggestions?

Hmm, we are already quite tied to stylua so switching would not be done lightly. Can you explain a bit what the advantages would be?

We will format the emmylua doc, and then we will support more options. This is not about asking nvim to switch formatters; we are simply exploring a potentially better direction for a lua formatter.

Formatting annotations would be nice.

No, of course not, but that's the only basis I can give input on ;)
