Is it possible to add LuaSocket module to the Moho?

This is from a previous discussions:


I did find an out-of-the-box Windows binary 5.4 LuaSocket implementation that worked: https://github.com/alain-riedinger/luasocket. Release: https://github.com/alain-riedinger/luas ... /3.0-5.4.3

This just requires updates to path and cpath to point at the installed-to directory (scriptresources in my case), and then use.
...
Connection Test: ...
Simple HTTP Request *: * Note: There is a slight issue with this shipped LuaSockets build (which is 3 years old - and contains an old compatibility buglet) when using HTTP and Lua 5.3/5.4. (see: https://github.com/lunarmodules/luasocket/issues/331). The quick fix is to: Update/Replace all receive() calls in http.lua and tp.lua with receive("*l")

Thank You Sam! I will check it out...

Your solution works great!
My idea is to create an external app to cominucate with Moho using localhost, do you think it works?

Code: Select all

    package.path = package.path .. ";" .. moho:UserAppDir() .. "/scripts/scriptresources/?.lua;"
    package.cpath = package.cpath .. ";" .. moho:UserAppDir() .. "/scripts/scriptresources/?.dll;"

Sam, would you please tell me where (in which file) , I can set those path and cpath settings?

Thank you very much for sharing. I tested it on Windows and it worked successfully. However, on Mac, I referred to the Windows configuration to write the Makefile, and after compiling, I got the error 'dynamic libraries not enabled; check your Lua installation' when trying to call it.

error loading module 'socket.core' from file '/Users/xxx/moho/user_define_content/Moho Pro/Script/ScriptResources/socket/core.dylib': dynamic libraries not enabled; check your Lua installation

Through my search, I found a possible explanation: it seems the Mac version of Moho needs to be built with the “LUA_USE_DLOPEN” macro added during its compilation.
