2010-12-29Literal lists (i.e. list quoting).David Robillard1-15/+14
Compile type expressions. Only compile a top-level function if program has code to run (i.e. isn't just definitions). Cast tuples to Object when necessary to avoid LLVM IR type mismatches (for cons stores and return values). Fix memory leaks. git-svn-id: http://svn.drobilla.net/resp/resp@369 ad02d1e2-f140-0410-9f75-f8b11f17cedd

2010-12-25Simplify let to fn, rather than deal with it through to compilation.David Robillard1-0/+2
The previous implementation of let was a premature optimization intended to make let cheap/free, but screws up closure creation and variable indexing because a new scope is created by something other than fn. Only compile top level expressions to globals (with associated store/retrieve overhead) in a REPL when it is necessary. Add `do' form (ala scheme `begin') to backend (used by `match' simplify). git-svn-id: http://svn.drobilla.net/resp/resp@348 ad02d1e2-f140-0410-9f75-f8b11f17cedd

git-svn-id: http://svn.drobilla.net/resp/resp@278 ad02d1e2-f140-0410-9f75-f8b11f17cedd
2010-12-02Represent code as list structure (i.e. traditional LISP lists built from ↵David Robillard1-44/+19
pairs), rather than tuple structure. Remove unused/crufty depoly stage. Remove cps from AST interface (but keep cps.cpp code around for later). Improved command line interface for compilation stages (options -T -L -S). git-svn-id: http://svn.drobilla.net/resp/resp@277 ad02d1e2-f140-0410-9f75-f8b11f17cedd
2010-12-01Add -T option to type-check and pretty-print with type annotations.David Robillard1-8/+13
Rename -p to -P (all 'stage' options, i.e. -P -T -S are uppercase for consistency). Clean up main program. Decent pretty printing. git-svn-id: http://svn.drobilla.net/resp/resp@275 ad02d1e2-f140-0410-9f75-f8b11f17cedd

2010-08-22Simplify Engine function compilation interface.David Robillard1-4/+6
Removes duplicated code in various backends and reduces Engine code knowledge of AFn specifics (which belongs in compile.cpp). git-svn-id: http://svn.drobilla.net/resp/resp@268 ad02d1e2-f140-0410-9f75-f8b11f17cedd
2010-08-22Simplify Engine::startFunction.David Robillard1-2/+2
git-svn-id: http://svn.drobilla.net/resp/resp@267 ad02d1e2-f140-0410-9f75-f8b11f17cedd
2010-08-19Generalise `cons': a call to any symbol beginning with an uppercase characterDavid Robillard1-1/+1
(i.e. a type symbol), e.g. (Thing 2), is a call to a type constructor which creates a Tup containing the arguments, with the symbol as the first element in the type expression, e.g. (Thing 2) has type (Thing Int) and compiles to a tuple containing a single Int. The type constructor `Tup' can be used as a `cons' replacement to construct generic tuples. git-svn-id: http://svn.drobilla.net/resp/resp@264 ad02d1e2-f140-0410-9f75-f8b11f17cedd
2010-08-19Coherent AString and Lexeme implementation.David Robillard1-10/+13
A Lexeme is any "token" read from input, a lexeme has not yet beeen parsed and could parse to anything, e.g. a string, an expression, a number, etc. Lexemes are not (yet?) exposed to the language or ever compiled. A String is a string literal, which can contain any character directly except " and \. There are two special escapes: \" and \\, any other character following a \ is a syntax error. Fix garbage collection of REPL objects, leading to type errors from type variable re-use because a type variable for a given AST's /address/ exists, but that address has actually been deleted and reused by new (i.e. make top level REPL expressions and types be GC roots). git-svn-id: http://svn.drobilla.net/resp/resp@261 ad02d1e2-f140-0410-9f75-f8b11f17cedd
2010-04-13Better error reporting when unification fails (report both locations, and ↵David Robillard1-7/+25
preserve locations during substitution). git-svn-id: http://svn.drobilla.net/resp/resp@256 ad02d1e2-f140-0410-9f75-f8b11f17cedd
2010-04-13Restructure as a source translation based compiler.David Robillard1-33/+76
Implement support for closures (via lambda lifting phase). git-svn-id: http://svn.drobilla.net/resp/resp@254 ad02d1e2-f140-0410-9f75-f8b11f17cedd

2009-10-14Remove unnecessary cenv.compile wrapper.David Robillard1-2/+2
Remove special treatment of symbols for compilation. Make CEnv::vals a <ASymbol*, CValue> map rather than <AST*, CValue> (only used for symbols). git-svn-id: http://svn.drobilla.net/resp/tuplr@214 ad02d1e2-f140-0410-9f75-f8b11f17cedd
