a bit more renaming
2009-02-01 05:41:43 +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 9716ee3452 making list a builtin

adding tablep and table.clone

fixing bug with filename string in load
2008-12-22 06:36:50 +00:00
JeffBezanson dfacb4d897 making all builtins print readably; (builtin 'sym) function
hash table functions:
adding get,put,has,del,table.foldl,table.pairs,table.keys,table.values
2008-12-21 05:55:00 +00:00
JeffBezanson 6962211e76 changing representation of cvalue types so each type is
explicitly represented in an fltype_t struct, and symbolic
types are hash-consed. a lot of code is smaller and simpler
as a result. this should allow more features in less space
(both code and data) going forward.

changing \DDD and \x escape sequences to read bytes instead of
characters

re-fixing uint64 cast bug

adding Paul Hsieh's hash function, to be evaluated later
2008-12-11 04:04:17 +00:00
JeffBezanson a4bb09bcb2 adding equalhash.c
some cleanup

moving some library code around for size optimization

now using == instead of flt_equals for float comparison, mostly
for hash compatibility
2008-11-28 21:44:59 +00:00
JeffBezanson e7e5677d51 support reading hex float literals
better text representation of infs and nans

removing construction of low-level numeric types directly from strings

adding hash function corresponding to equal

better way to initialize builtins

moving advanced bitvector ops to separate compilation unit

rearranging hash table code so it can be specialized for different
comparison functions

one good way to bloat a piece of software is to add several
ASCII pictures of the mona lisa
2008-11-23 07:12:37 +00:00

2008-11-06 04:04:04 +00:00
JeffBezanson 120522c212 updating bitvector functions to use int64s in more places, since
