v4.1.5
|
|
|
|
* renamed test--> to test-->>
|
|
|
|
* added a new test--> that only tests for a single step in the
|
|
reduction sequence
|
|
|
|
* added #:cycles-ok flag to (what is now called) test-->>
|
|
|
|
* define-metafunction and reduction-relation now work better with
|
|
Check Syntax
|
|
|
|
* added the #:arrow keyword to reduction-relation, which lets you use
|
|
a different main arrow (mostly useful for the typesetting)
|
|
|
|
* added domain specifications to reduction relations via
|
|
the #:domain keyword
|
|
|
|
* 'traces' copes better with errors during reduction
|
|
|
|
* initial-char-width now accepts functions to give finer grained
|
|
control of the initial widths of the terms.
|
|
|
|
* traces & traces/ps: added the ability to specify a mixin
|
|
to be mixed into the graph pasteboard
|
|
|
|
* added built-in patterns natural, integer, and real
|
|
|
|
v4.1.4
|
|
|
|
* added redex-check, a tool for automatically generating test cases
|
|
for Redex specifications.
|
|
|
|
* improved traces for use in generating PostScript:
|
|
|
|
- added traces/ps
|
|
|
|
- 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! and related term-node functions
|
|
|
|
* Added tracing to metafunctions (see current-traced-metafunctions)
|
|
|
|
* added caching-enabled? parameter (changed how set-cache-size!
|
|
works)
|
|
|
|
v4.1.2
|
|
|
|
- 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

|
or similar things via reduction-relation, metafunctions, etc.

("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.

differences in the presence of quote (by disabling the '

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 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 reduce-all (use apply-reduction-relation* insetad)
|
|

|
reduction rules.

|
|
|
- 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 _!_ 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

|
|
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)
|
|
|

|
|
of the examples to use labels)

|
|
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.
