accepting r6rs IEEE literals +-nan.0 and +-inf.0
printing distinguished -0.0, indicating float with .0f instead

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 209b77a534 simplified and improved some of the prettyprinting logic
• eliminated bad behavior near screen edge, added wrapping
• added behavior: indent after some number of non-indented elements
• indent after head symbols with really long names
• don't indent after first argument to setq

improvements to cps converter
• correctly dispatch to non-cps functions
• handle vararg lambdas in head position
2009-01-03 05:30:22 +00:00

adding string.find function

fixing bug in #sym(...) if sym was undefined
2008-12-24 04:43:36 +00:00

2008-12-21 05:55:00 +00:00
JeffBezanson b5dda68eab adding support for finalization of values

allowing GC to be triggered by large buffer allocations

adding hash table constructor and print function

renamed some functions
2008-12-20 06:16:00 +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
JeffBezanson 120522c212 updating bitvector functions to use int64s in more places, since
after all that's the whole point of bitvectors

some prettyprinting tweaks

more uniform way to handle forwarding pointers. fix forwarding
of gensyms

:keyword symbols
2008-10-31 02:50:00 +00:00
JeffBezanson c8c59b1dfc added globals *install-dir* and *print-width*, parameterized

2008-08-16 21:15:36 +00:00
JeffBezanson 46f2f47b14 switched to 3-bit type tags for simpler checking
fixnums still have 30 bits

moving towards making "guest functions" more opaque; their type is now
just 'builtin

pretty printing some forms better: defun, defmacro, for, label
support *print-pretty*
2008-08-05 01:43:12 +00:00
JeffBezanson c3811312a7 adding vector.map, string.char
