terra

The Terra language


local terra = require'terra'

This is a slightly modified build of the Terra library which allows the Terra runtime to be loaded from Lua as a Lua/C module. The terra module exposes the complete Terra Lua API and installs a require() loader for loading .t files from the same locations that are used for loading Lua files.

NOTE: Terra only runs on x86-64!

NOTE: On Windows Terra is compiled with luapower's mingw64 toolchain so there's no need to install Visual Studio to use standard C headers. Instead, mingw64 headers are provided in the [mingw64-headers] package.

Building

Building terra requires llvm.

Bundling

Bundling terra requires bunding in the llvm static libraries. There's a script documenting what these are that can be used with bundle directly:

bundle ... -a terra -a "$(csrc/terra/bundle-libs)"

Changes to terra

The source code changes made to terra were kept to a minimum to make it easy to to merge upstream changes back into the luapower terra fork. This is similar to how dynasm was modified for luapower. Anyway, the changelist:

  • the terra dynamic lib does not bundle luajit and is instead exposed as a normal Lua/C module that must be included with require'terra' from Lua.
  • LuaJIT was modified to require'terra' if loading a *.t file, and to load the file via _G.loadfile instead of lua_loadfile.
  • loadfile was overloaded to interpret *.t files as Terra source code.
  • terralib.lua and cudalib.lua are not bundled into the binary, and are provided separately.
  • strict.lua is not loaded and not included (it's included with luajit and must be loaded manually as needed).
  • std.t and parsing.t were renamed terra_std.t and terra_parsint.t. respectively and are now in the luapower dir along with all Lua files.
  • the system include paths are set for [mingw64-headers].
  • the location of clang's resource dir is set for [clang-resource-dir].
