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

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

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

JeffBezanson c8c59b1dfc added globals *install-dir* and *print-width*, parameterized
prettyprinter by screen width

decent accumulate-while and accumulate-for

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 9acdf313b9 adding more ios functions
porting femtolisp to use ios for all I/O
2008-08-17 18:16:31 +00:00
JeffBezanson fa0e134dd8 adding "d.df" syntax for reading single-precision numbers
misc. fixes
more work on ios

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 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
