My candidates for UCI LISP functions that are useful enough to put
into T, with suitable modifications (e.g., stream parameters):
NEWSYM & friends, READLIST, PRINA & friends, ERRSET, FSCNT & friends,
GETDEF, UNION & friends, TCONC & LCONC, LINEREAD, NODUPLES, SORT,
REPEAT, LSUBST, SUBLIS, TIMER.
I've implemented some packages that I've been meaning to announce,
but I haven't quite gotten around to it (until now).
A sort package for vectors and lists.
a large set of machine independent routines for manipulating
dates, times, and intervals. Even a date parser! I have not
yet debugged this, but I wouldn't want anyone else to waste
their time implementing this sort of thing.
a record package for defining "record structure overlays" on
top of byte vectors
a flexible terminal independent output package. This is
intended for U, but I could make it more general.
a large set of string manipulation routines that are "missing"
a teeny grep-through-the-oblist function. e.g. (apropos
"fixnum") is supposed to print all of the known symbols that
contain the substring "fixnum".
REGULAR EXPRESSION COMPILER
Compiles a regular expression notation into T code that will scan
for that expression in a stream. This isn't done yet, I just
want to say that I'm doing it.
An undebugged implementation of associativee tables.
A function that returns a closure that returns all of the
subsets of the integers from 1..n-1 in some particular order.
Computes the longest common subsequence of a "set of strings"
(or a list of lists of symbols, etc.)
A small set of routines/operations for doing explicit storage
management. Great for performance tuning/introducing bugs.
