This is a cross-platform LuaJIT/FFI wrapper for Steamworks. The library provides easy and simple Steamworks integration, using the original redistributable binaries provided by Valve.

This project has been retired as of August 3, 2022

Code: Select all
ffi.C.strtoull("0xffffffffffffffff", nil, 16)
LuaJIT accepts a ULL suffix for this.

Yeah, I mean, it's LuaJIT-exclusive anyway, you can't make this work in regular Lua.

Thanks grump, I will add that change although I have tested it and it works fine with either:
Code: Select all
a = ffi.C.strtoull("0xffffffffffffffff", nil, 16)
b = ffi.C.strtoull("0xffffffffffffffffULL", nil, 16)
assert(a == b)
In general, pure Lua can't handle such large numbers:

The point is that you can use the ULL suffix to write 64 bit integer literals directly in LuaJIT, there's no need to call strtoull.
Code: Select all
assert(0xffffffffffffffffULL == ffi.C.strtoull("0xffffffffffffffff", nil, 16))
(see "Extensions to the Lua parser" at the bottom of the page)

I see, that's even better. I will have to see how this change would affect the rest of the code.
Thanks grump!

Just pushed an update upgrading the library to Steamworks v1.5.
This version includes supports for HTTP and HTTPS requests similarly to luasocket:
Code: Select all
valid = steam.request(url[, body, callback])
That's right, we've got working SSL support too!

I know this might be a silly question:
Where should I put libsteam_api.dylib in a Mac build?
I tried to put libsteam_api.dylib in the folder, inside .love file or in love.exe's folder.
None of them worked.
Error
dlopen(libsteam_api.dylib, 5): image not found

On Mac, I placed mine in:
Code: Select all
Contents/Frameworks/libsteam_api.dylib
Please confirm if this works for you.
