Jesse D. McDonald	c01f0838f1	Misc. reader improvements, plus ability to run .rla directly. Fix tree_replace() to handle recursive data structures. Fix some other minor bugs in the reader and interpreter. Implement comment-escapes in the string parser, for more readable input. Allow input program files (.rla) to be invoked directly, with arguments. Add a simple string->number converter as a builtin function.	2012-07-14 13:38:48 -05:00
Jesse D. McDonald	10fbc269c5	Implement the remaining bytecodes. Adjust some of the numbering. Also, use #<undefined> for "not yet initialized" and #f for "no value".	2012-07-14 13:38:40 -05:00
Jesse D. McDonald	61e0583932	Implement bytecode, other than floating-point operations.	2012-07-14 13:38:38 -05:00
Jesse D. McDonald	0a2f13b523	Added built-in structure types and interpreter core (w/o bytecode). Improved timing resolution by using clock_gettime() instead of clock(). Also gave project a name: Rosella. Play on 'Parrot' (Perl 6 VM).	2012-07-14 13:38:02 -05:00
