more renaming (? on predicates, ! on mutating operators)

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

not very nice

adding opaque type boilerplate example file

adding correctness checking for the pattern-lambda benchmark

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 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

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 6f934a817b I decided it was rather random that set was the only function
that could access the current environment dynamically. It also
differed unnecessarily from common lisp set in this respect.

So now setq is a builtin special form that sets lexical or
global variables, and set is a function that sets global variables.

Rather than eliminate the power of the dynamic set, I extended it
by adding eval*, which evaluates its argument in the current
environment. The justification for this is that the interpreter
is already dynamic enough to allow it with no overhead, so the
ability might as well be exposed.

cleanup; removing some magic numbers

beginning hash tables
2008-09-06 22:19:51 +00:00
JeffBezanson d6470ac62f fixed array constructor so it doesn't require allocating a generic

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*
