- added more coloring arguments to traces: #:scheme-colors?
#:default-arrow-highlight-color, and #:default-arrow-color
- added the #:layout argument to traces
- added term-node-set-position!
- Added tracing to metafunctions (see current-traced-metafunctions)
- added caching-enabled? parameter (changed how set-cache-size!
works)
v4.2
- added white-bracket-sizing to control how the brackets
are typeset when rendering a metafunction.
- added render-* functions that make it easier to experiment
with typesetting at the REPL.
- where clauses in metafunctions now are implicitly in
`term's (they were not documented at all before)
v4.1 (this is the first version that was included in the PLT
distribution. Before this, Redex was in PLaneT).
EXTENSIONS:
- added test-equal, test-pred, test-reduces, and test-results
- removed restriction on apply-reduction-relation*
replaced it with additional work while matching
non-terminals to remove the redundancy
- added `in-domain?'
CHANGES:
- define-metafunction and co. now use a different syntax.
- got rid of named holes. This means, eg, that (hole #f) now matches
a two element list, not just the hole directly.
- zero occurrences of a hole when matching an `in-hole' now
correctly fails.
- the `where' keyword in reduction-relation became `with' (and the
arguments reversed order)
- renamed the `rib' struct to `bind' (and mismatch-rib =>
mismatch-bind)
- merged the various traces functions into a single
function that accepts keyword arguments.
- renamed the loc-wrapper struct to lw.
- language->ps and language->pict's listof-symbols is now
optional and thus the language->ps's arguments changed
order to make that work.
- renamed test-match to redex-match
- no long export mtch struct or bindings struct and
test-match's result is not simplified.
- extend-reduction-relation now uses the names of the
rules to replace existing rules (instead of just
unioning the rules)
- in-hole used to substitute into named holes, but now it
only substitutes into unnamed holes. Use in-named-hole
on the right-hand side to do the substitution
- removed hole-here
BUG FIXES:
- fixed a (not easily noticed) bug in the way hole
matching worked for named holes.
- extending a non-terminal that's been defined together
with other non-terminals now works as expected.
- handling of non-terminals uses that have underscores in
them now works properly (only showed up when using them
in the definition of a langauge)
- an extended language can now define multiple non-terminals
together

below here were the versions of Redex that appeared in PLaneT
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
("robby" "redex.plt" 4 4)
- undid some changes that broke backwards compatibility
("robby" "redex.plt" 4 3)
- added extend-reduction-relation
- fixed a bug whereby reduction relations that reduced to
false were always ignored
("robby" "redex.plt" 4 2)

("robby" "redex.plt" 4 1)
- improved stepper so that scrolling works when large
terms are present.
("robby" "redex.plt" 4 0)

w/out subscripts bind in reduction rules (but they still
do not bind in grammar definitions).
- wheres and side-conditions now bind as expected in
reduction-rules
- fixed a bug in metafunction pict generation (parallel
fix from 3.28)

- ??
("robby" "redex.plt" 3 21)
- added `where' as a binding form in the individual
clauses of a reduction-relation.

("robby" "redex.plt" 3 20)
- improved the interface for rewriting aspects of the typesetting.
- added linebreaks, with-compound-rewriter, and with-atomic-rewriter
("robby" "redex.plt" 3 19)
- improved source locations for error messages when misusing ellipses, eg:
(term-let ([(x ...) '(1 2)] [(y ...) '(1 2 3)]) (term ((x y) ...)))
or similar things via reduction-relation, metafunctions, etc.
- fixed PR 8752: `name' patterns only show the name,
leaving the thing defined to the where clause
("robby" "redex.plt" 3 18)
- fixed PRS relating to pict generation: 8749 8751 8750
and a few other bugs along the way.

- added variable-not-otherwise-mentioned as a new pattern
- added stepper/seed
- added an optional pretty-printing argument to stepper.
- improved the ps rendering of the arrows
for --> -> => ==> ~> and ~~>
- rewrote internals of pict rendering (hopefully no change
yet, but there may be bugs introduced ...).
("robby" "redex.plt" 3 12)
- Added pict and .ps generation functions for
reduction-relations, metafunctions, and grammars. These
are still primitive; the most obvious missing feature is
the inability (without secret knowledge) to replace the
pink stuff.
- fixed a bug in the way the stepper highlights
differences in the presence of quote (by disabling the '
shortcuts printing)

- changed the order of the arguments in the new `fresh' clauses
introduced in the last release.
("robby" "redex.plt" 3 10)

This release changes the syntax of the reduction relations
to make it more consistent and more in line with the way
reduction relations are written in papers. This is the
precise set of removals and additions:
- added extend-language
- added reduction-rule & apply-reduction-relation
- added union-reduction-relations
- added define-language
- changed compatible-closure & context-closure so that the
pattern argument is not quoted, but is just the pattern
in the last argument.
- changed term-node-labels so that it can return #f (in
the list) when a reduction doesn't have a label.
- removed language->predicate, compile-pattern,
match-pattern (use test-match instead)
- removed reduction, reduction/name, reduction/context,
reduction/context/name (use reduction-relation instead)
- removed red? (use reduction-relation? instead)
- removed reduce (use apply-reduction-relation instead)
- removed reduce-all (use apply-reduction-relation* insetad)
- removed reduce/tag-with-reduction (use
apply-reduction-relation/tag-with-names instead)
- removed red-name, reduction->name, give-name
- removed language (use define-language instead)
- removed helper.ss
Other improvements:
- check syntax draws arrows for the non-terminals in a
`language' now, both to the language and to the
reduction rules.
("robby" "redex.plt" 2 6)
- added reduce-all and note about bad parsing performance
issues.
- added `test-match' and note about how to debug redex
programs to doc.txt
- added redex-specific 'check' functions for use with
schemeunit.
- add `metafunction' for defining meta functions using the
pattern matching notation used in reductions and grammars.
("robby" "redex.plt" 2 5)
- fixed bugs in compatible-closure & context-closure
("robby" "redex.plt" 2 4)
- reduced the amount of memory used for caching
significantly (with some small speedup for
a largeish reduction semantics test suite)
- added set-cache-size!
- added variable-prefix pattern
- added ..._<id> pattern that can be used to ensure matching
lengths of repeated patterns.
- added _!_ subscripts (both in ... and regular) to ensure
that the matched things are different (or have different
lengths in the case of ..._!_ subscripts)
("robby" "redex.plt" 2 3)
- added the ability to traverse the graph generated by
traces in order to decide if a term should be
highlighted in red. See the traces/pred documentation
for details.
- added term-node functions
- added red-name function
- removed make-plt.ss from archive
("robby" "redex.plt" 2 2)
- added a blurb, fixed a typo in the docs.
("robby" "redex.plt" 2 1)
- changed the way a contract is specified on the matcher
to get a 30% speed up on the beginner test suite.
Thanks, Matthew for spotting that!
("robby" "redex.plt" 2 0)
- fixed a bug in compatible-closure handling that could
result in duplicate matches when there should only have
been a single match.
- added labels to edges for reductions
when shown in GUI. See docs for
reduction/name
- small performance improvement to matcher
(10-20% on non-trivial examples)
- added letrec.ss example (and improved some
of the examples to use labels)
("robby" "redex.plt" 1 3)
- Fixed a bug in the the compatible closure function; otherwise the
same as 1.1
("robby" "redex.plt" 1 2)
- Obsolete'd version. It used to be a first attempt at the 2.0
revision, but now should be avoided.
Use 2.0 instead of this version.
("robby" "redex.plt" 1 1)
- fixed packaging error
("robby" "redex.plt" 1 0)
- initial release to PLaneT
