JeffBezanson c42ee12d4c allowing multiple expressions in lambda
making cond a macro
increasing size limit for cvalues on the managed heap, and inline
  allocated hashtables
2009-05-29 04:38:50 +00:00
JeffBezanson bfbbf051c9 doing a better job hashing circular structure. the hash function is now
always fast and gives conservative correct answers, at the expense of
fidelity on medium and large size structures. for example (hash (iota 15))
gives the same result as (hash (iota 14)).

JeffBezanson 2cf5187ca9 adding dump, memstream, io.read, and io.write
more renaming
allowing iostreams to be read-only
fixing bug allowing arrays with 0-size elements
2009-03-02 04:26:16 +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

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

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

decent accumulate-while and accumulate-for

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
