a0bb0430f2 separated the define-judgment-form implementation (and bind-withs)

55b3d99d78 adjust beaucoup places in redex where the source was being 
included in the compiled files. (also, misc minor cleanups
notably a new exercise in tut.scrbl)

closes PR 12547 --- there are still a few uses left, but they do not
seem to be coming from Redex proper:

 - /Users/robby/git/plt/collects/racket/private/map.rkt still appears
   in a bunch of places (there is a separate PR for that I believe),
   and

 - /Users/robby/git/plt/collects/redex/../private/reduction-semantics.rkt
   appears in tl-test.rkt, but I do not see how it
   is coming in via Redex code, so hopefully one of the other
   PRs that Eli submitted is the real cause. If not, I'll revisit later

b3c450ffc9 add 'side-condition' to define-judgment-form (it does not have an implicit 
unquote like the other side-condition's do, but it is still useful
for typesetting purposes)

f1a7864c63 fix bug in lw struct generation 2012-01-09 20:38:51 -06:00
Robby Findler
4fab7f76af tweak the compiled representation of lw structs so they take less space 
this shrinks the size of redex/examples/r6rs/r6rs.rkt's .zo file by about 25%

2afda360d0 redex: adjust the test suites to clean up a few things; also make the

0459e4fbcd redex: when there are no duplicate names in a pattern, don't do the 
same-name-same-bindings check

this seems to speed up the r6rs test suite by about 12% and the
lambdajs benchmark by about 25%

160fcacad6 redex: fix bug introduced in recent optimization attempts 2012-01-02 22:21:21 -06:00
Robby Findler
fe1df742b3 Tried to improve redex by detecting when a pattern does not 
have any holes, hide-holes, or names and, in that case, just
combining booleans instead of building of mtch structs.

This does seem to work on a simple benchmark. The code below
gets about 6x faster. But on the r6rs test suite, there is
no substantial change (possibly because the caching obviates
this optimization?)

lang racket/base
(require redex/reduction-semantics)
(caching-enabled? #f)
(define-language L (e (+ e e) number))
(define t
  (let loop ([n 100])
    (cond
      [(zero? n) 1]
      [else `(+ 11 ,(loop (- n 1)))])))
(define f (redex-match L e))
(time (for ([x (in-range 1000)]) (f t)))

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

f725066bf9 fix bug in the handling of side-conditions 2011-12-05 01:14:54 -06:00
Robby Findler
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)
