9bcb86eb0c redex: minor cleanup 2011-12-29 10:15:52 -06:00
Robby Findler
5b2d378a77 fixed a bug in recent Redex internal pattern rewrite 
(discovered by the random testing done for the racket machine model)
 2011-12-28 23:52:56 -06:00
Robby Findler
f1bacffbdc Adjusted rewrite-side-condition/check-errs so that it normalizes the internal 
redex patterns a bunch:

- repeats are turned into wrappers in sequences,
- names are all explicit,
- non-terminals are wrapped with `nt',
- cross patterns always have the hyphens in them.
- ellipses names are normalized (so there are no "hidden"
  name equalities); this also means that repeat patterns
  can have both a regular name and a mismatch name

Also, added a match-a-pattern helper macro that checks to make sure
that functions that process patterns don't miss any cases

25dd8727cb add datum-case', etc. as syntax/datum' 
This library is used by Redex, which wants a `syntax'-like template
language, but for datum values instead of syntax objects. Using
`datum-case' and `datum' generates much less code. Redex uses
only a small part of the general functionality, so adding
`syntax/datum' could be overkill. It's implemented by generalizing
the `syntax-case' and `syntax' pattern matching and template
constructing code, though; it's not a lot of extra code, and it's
easiest to generalize completely. We may find other uses for
datum templates, too.

622bec0719 avoid (format "~s" x) in favor of (symbol->string x) for symbols 
when doing typesetting stuff in Redex, as the former seems to have
some kind of context dependency that makes it insert ||s around
some upper-case symbols sometimes

e788c6f49e adjust define-judgment-form so that it 
a) avoids creating big intermediate lists of the same things over and over
   (this closes PR 12380)
b) generates less code (by generating calls to local functions)
c) normalizes its output (sorts by the printed representation)

64dfdb3c7f Change the expansion of reduction-relation so that it generates less code 
(by expanding into a call to a 30 or so line procedure, instead of putting
that code directly into the result of the macro).

This produces about a 6x speedup on this reduction-relation

  (reduction-relation L (--> 0 1) (--> 1 2) ... (--> 99 100))

where L is

  (define-language L)

The time it takes to run "racket r6rs.rkt" in the shell from the
directory collects/redex/examples/r6rs speeds up by about 10% (15%
with errortrace enabled), in the case where all .zo files are built,
except the ones in the r6rs directory. (Also worth noting that "racket
-l redex" takes more than 50% of that time.) And the change has no
noticeable effect on the time it takes to run r6rs-test.rkt.
