Titan is a programming language, based on the syntax and semantics of Lua, to be a statically-typed, ahead-of-time compiled sister language to Lua. Converting Lua code to Titan should yield a significant speedup, in some cases approaching the speed of C code. Unlike C, Titan is garbage-collected, and has nice high-level programming features such as first-class functions, objects, and generics. Unlike other statically-typed, garbage-collected languages, Titan is designed to interoperate seamlessly with Lua: Titan's native objects are kept in Lua's garbage-collected heap, and can be traced by Lua's garbage collector. Titan objects can be passed to Lua code, and Lua objects can be used by Titan code (although with a performance penalty compared to working with Titan objects).
The Titan compiler is under development and it is still compiling Titan modules to Lua code, but in the future it will compile them to C code. For more information, please, see the reference manual.
- Lua >= 5.3.0
- LPeg >= 1.0.0
Titan must be installed in a standard location; LuaRocks will do this, and will also install the LPeg dependency automatically.
$ [install luarocks]
$ luarocks install titan-lang-scm-1.rockspec
$ tlc [options] [filename]
-h print this help
-d name dump the AST (after typechecking) to file 'name'
-o name output to file 'name' (default is 'tlc.lua')
-c ansi colors on
-p print the AST in Metalua format (before typechecking)
-s strict mode on
-v print current version
-w warnings on (consistent-subtyping, unused locals)
Titan also provides a runtime loader to use Titan modules on any standard Lua virtual machine:
require "titan-lang"
package.path = "./?.tl;" .. package.path
-- It will load my_module.tl if it exists:
local my_module = require "my_module"
local my_file = loadfile "my_file.tl"The loader functions use the file extension (chunk name extension in the cases of load and loadstring) to decide whether it contains Titan (.tl) or plain Lua. If you want to force loading the chunks as Titan you can use the functions provided by the titan-lang module (these work like their standard Lua counterparts):
local tl = require "titan-lang"
tl.loadstring(string, chunkname)
tl.load(func, chunkname)
tl.loadfile(filename)
tl.dofile(filename)Released under the MIT License (MIT)
