This experimentation with build.zig has served its purpose; I am currently working on a similar project which uses zig with ziglua.
A portable lua distribution that is isolated from environment variables.
-
luaiso The interpreter.
-
lpeg The lpeg parsing library. (The re module is also included)
-
lfs The luafilesystem library.
-
socket [ -Dluasocket ] The luasocket networking library.
-
ssl [ -Dluasec ] The luasec library.
-
lanes [ -Dlanes ] The lanes multithreading library.
Further lua libraries may be installed into the share path (share/lua/5.4). Further native modules may be installed into th lib path (lib/lua/5.4).
This distribution of lua should be self-contained within the directory structure. This folder
can reside anywhere on your computer. Environment variables are not consulted and consequently
luaiso will not run init scripts, or modify the configured path. On POSIX systems (assuming a procfs)
/proc/self/exe is used to determine where to point package.path and package.cpath, and on windows
executable relative paths are used by lua as a default.
It may be desirable to put the bin directory in your user path, optionally creating a shim for lua.
If you intend to build luasec you will need to install vcpkg.
This is used to build openssl across multiple platforms.
Example build which includes the optional libraries lanes and luasocket:
> zig build -p <where you want it to spit the build out> -Dlanes -Dluasocket
Full build of everything:
> zig build -p <where you want it to spit the build out> -Dall
