plus one more test

JeffBezanson ff650e3049 fixing hash function to do a better job on long lists. 2009-05-20 04:30:00 +00:00
JeffBezanson bfbbf051c9 doing a better job hashing circular structure. the hash function is now
always fast and gives conservative correct answers, at the expense of
fidelity on medium and large size structures. for example (hash (iota 15))
gives the same result as (hash (iota 14)).

changing / to do real division always

JeffBezanson 4cb9685266 adding support for arbitrarily-long argument lists
argument lists are heap-allocated after a certain cutoff (currently 127)
2009-03-27 03:06:55 +00:00
JeffBezanson 17d81eb4e6 adding #b, #o, #d, #x numeric literals
accepting r6rs IEEE literals +-nan.0 and +-inf.0
printing distinguished -0.0, indicating float with .0f instead
of #float, double with .0 instead of #double

more renaming (? on predicates, ! on mutating operators)
changing T to #t :( all those #s are so ugly
2009-02-01 01:53:58 +00:00
JeffBezanson a55b46e9a6 switching to scheme #t, #f, and () values
porting code to sort out which NILs are false and which are
empty lists

switching to scheme-style special forms. however you feel about
scheme names vs. CL names, using both is silly.

mostly switching to scheme predicate names, with compatibility
aliases for now. adding set-constant! to make this efficient.

adding null?, eqv?, assq, assv, assoc, memq, memv, member

adding 2-argument form of if
allowing else as final cond condition

looking for init file in same directory as executable, so flisp
can be started from anywhere

renaming T to FL_T, since exporting a 1-character symbol is
not very nice

adding opaque type boilerplate example file

adding correctness checking for the pattern-lambda benchmark

bugfix in int2str
2009-01-29 01:04:23 +00:00
JeffBezanson 830e1c986c renaming 'char' type to 'byte' to avoid confusion
wchar will be used for all individual characters

adding string.find function

fixing bug in #sym(...) if sym was undefined
