Moonshot is a fork of DMD, the reference compiler for the D programming language.
It implements a Lua 5.x backend for the @safe subset of D, based on AST conversion.
It aims to compile a reasonable subset of @safe code, so that high-level D can be used
in scripting environments (i.e. games, scriptable applications, and more.)
This project was inspired by Adam D. Ruppe's dtojs, which took a similar approach.
Currently, its support of D functionality is limited, but includes:
- Functions: free, literal
- Expressions: strings, numbers, unary/binary operations (inc. assignment), calls
- Arrays: literals, indexing
- Control flow:
if,for,while,do,foreach(inc. tuples),break,switch - Structs:
init, methods, member variables, enough to use ranges extern (Lua)binding: functions, namespaces, classes/structs, op overloading- Metaprogramming: should work Out Of The Box™, including templates, mixins, and more
Notable exclusions include:
- Pointers/references
- Slices
continue,goto- Classes
- Exceptions
try finally, destructors,scope (exit)- Associative arrays
- Any kind of optimised code generation
- ...and more.
These missing features should hopefully be implemented over time.
To use, compile your D source with Moonshot with the -lua switch.
Test cases can be found in test/lua, as well as work on a "runtime"; this
will be moved out when appropriate. To run tests, use rdmd lua_test.d in
the test directory.
Any references to Phobos in tests currently refer to unmodified Phobos.
