2009-02-24 02:21:16 +00:00
JeffBezanson 2c1bb59486 adding integer? and number->string
a bit more renaming
2009-02-01 05:41:43 +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 38cf75733e adding #; datum comment
allowing #||# comments to nest
2009-01-26 02:03:37 +00:00
JeffBezanson b99d8715ce generic aref/aset for all arrays
(string v) now works on any value, by printing to a string

some bug fixes in ios
2008-12-27 06:02:53 +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
2008-12-24 04:43:36 +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 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 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 9acdf313b9 adding more ios functions

misc. fixes
