ZLS version is for 0.12.0 (I put in into PATH and lua script and checked if some plugin puts builtin LSP which I dont need).

In config_gen/config.json:

        {
            "name": "enable_autofix",
            "description": "Whether to automatically fix errors on save. Currently supports adding and removing discards.",
            "type": "bool",
            "default": false
        },

And it still compresses my struct into a single line:

//before
const Container = struct {
    childs: std.ArrayList(),
    content: []u8
};

//after saving
const Container = struct { childs: std.ArrayList(), content: []u8 };

I tried to configure it in init.lua (I installed kickstart and did almost no changes):

        zls = {
          cmd = { 'C:/zig/lsp/1.12.0/zig-out/bin/zls.exe' },
          settings = {
            Lua = {
              format_on_save = false,
            },
          },
        },

And copypasted in Autoformat section right after lua’s formater

It is better if I fix it not only for nvim, but in ZLS config or whatever
