Lua rocks formatting addon for premake5

[lolrobbe2]

hello i am the developper behind the luarocks premake-language-support addon. the defenition files work great. but what i am wondering is if there is a way i can make a formating plugin for said premake5 scripts (see example script below).

the problem/question

As you can see the premake script is just a collection of function calls.
Premake5 uses indention to denote the scope (workspace,project, filter) etc.
Is it possible to make a plugin, and how would i generaly go about it?

workspace "WorkspaceName"
    architecture"x86_64"
    configurations { "Debug", "Release" }

    project "ProjectName"
       kind "ConsoleApp"
       language "C"
       targetdir "bin/%{cfg.buildcfg}"
    
       files { "src/**.c", "include/**.h" }
    
       filter "configurations:Debug"
          defines { "DEBUG" }
          symbols "On"
    
       filter "configurations:Release"
          defines { "NDEBUG" }
          optimize "On"

An addon can include a plugin.lua, but LuaLS plugins operate on the language-server analysis pipeline; they are not a replacement formatter API. The built-in formatter is EmmyLuaCodeStyle and is configured through .editorconfig / Lua.format.defaultConfig.

For Premake's indentation-by-function-call semantics, first check whether EmmyLuaCodeStyle can express the layout you need. If it cannot, the robust approach is a separate Premake-aware formatter that implements your editor's formatting command (or an LSP textDocument/formatting server), while keeping the LLS addon for definitions and diagnostics.

In other words: the definitions belong in this addon, but a formatter with Premake-specific scope rules should be its own tool. A LuaLS plugin.lua can inspect syntax and report diagnostics, but it cannot replace the formatter's output.

@hamedrabah could i make a formatter that could invoke the luals formatter and then format the know premake functions?
