JeffBezanson 8e4ba69a7b more efficient representation for small tables
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 b5dda68eab adding support for finalization of values
enabling type-specific print and relocate behavior

allowing GC to be triggered by large buffer allocations

adding hash table constructor and print function

renamed some functions

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

JeffBezanson c89111f7cb refactored escape sequence handling a bit, added error for invalid hex
discarding rest of input line after a parse error
made compare() do less work for unordered comparison
added peekc and purge to ios
2008-11-06 04:04:04 +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
prettyprinter by screen width

decent accumulate-while and accumulate-for
2008-09-11 02:37:38 +00:00
JeffBezanson af8b332367 fixed some small flaws in (compare) 2008-08-30 22:18:20 +00:00
JeffBezanson d6470ac62f fixed array constructor so it doesn't require allocating a generic
container first

updates and improvements to ios
2008-08-29 03:27:59 +00:00
JeffBezanson 6e515a532e fix oops in new apply()
more cvalues design
2008-08-07 05:08:10 +00:00
JeffBezanson 62e5c359d0 adding string.inc and string.dec
moving string functions to their own file
2008-08-05 04:34:14 +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
fixing 0-trip-count case in (for)
2008-08-02 16:18:39 +00:00
JeffBezanson e08091e4a1 adding (for lo hi f) construct, changing library funcs to use it
setting license to CPL v1
2008-07-26 22:04:02 +00:00
JeffBezanson 60644c760e made apply() entry point more efficient (now non-consing)
added selfevaluating(v) predicate
2008-07-26 04:03:48 +00:00
JeffBezanson 180b05fa8e storing environment size on the stack so lambda doesn't need to
compute it. changed penv from pointer to stack index.
result is best performance yet.

fixing constantp to be true for quoted values
2008-07-18 04:16:07 +00:00
JeffBezanson b3b2bc3300 fix to how defun was using macroexpand 2008-07-12 02:58:55 +00:00
