Haxe Lua target: dependencies

Hello everyone,

I am relatively new to the Haxe world but I enjoy the language a lot so far. Currently I am investigating the possibility to create externs for the Gideros Game Framework which uses Lua and - I think - would fit quite nicely with a Haxe-based development workflow. However, I have trouble getting even a short test to work. The main problem seems to be with the dependencies necessary.

Compiling a very simple Haxe script to Lua:

class Game {
	static public function main() {
		trace('Hello World');
	}
}

with the build.hxml:

-cp src
-lua main.lua
-main Game

does indeed create a potentially good-looking main.lua. However, it seems to require a few dependencies (as detailed in the manual) that need to be installed using luarocks. As Gideros is mainly its own platform unaware of luarocks, running the script fails with: main.lua:53: module 'lua-utf8' not found.

What options do I have now? Is it possible to somehow exclude the lua-utf8 dependency from the compilation or do I need to get Gideros to satisfy it (by either including it or making it aware of the luarocks folder)? Or am I missing something? I tried to get inspiration from the hxdefold project but can’t find anything related to my problem. How did they solve that (maybe Defold includes all dependencies already?).

Thanks a lot and again: Haxe is pretty great, I enjoy it a lot more than Typescript which I normally use, so it is a pity it is not more popular. Great work!

Try this build command.

It seems to work! Awesome, thanks.

Is that command documented somewhere? Maybe there are others that prevent future questions from my side… :wink:

You can find it in the lua section of the manual https://haxe.org/manual/target-lua-flags.html

Alright, not well hidden… I somehow missed it. Thanks!

There are a bunch of other not lua-specific flags, which you may find useful: https://haxe.org/manual/compiler-usage-flags.html
