+
+These #vars represent opcode properties that you may want as part of

-Generates the value of I<var>, left jutified to fill I<N> spaces.
+Generates the value of I<var>, left justified to fill I<N> spaces.

-=item B<~>
+=item B<#>I<Var>
-Any number of tildes and surrounding whitespace will be collapsed to

+This ucfirst form of #var generates a tag-value form of itself for

=head1 Using B::Concise outside of the O framework
-You can use B<B::Concise>, and call compile() directly, and
+The common (and original) usage of B::Concise was for command-line
+renderings of simple code, as given in EXAMPLE. But you can also use
+B<B::Concise> from your code, and call compile() directly, and
repeatedly. By doing so, you can avoid the compile-time only
-operation of 'perl -MO=Concise ..'. For example, you can use the
-debugger to step through B::Concise::compile() itself.
+operation of O.pm, and even use the debugger to step through
+B::Concise::compile() itself.
-When doing so, you can alter Concise output by providing new output
-styles, and optionally by adding callback routines which populate new
-variables that may be rendered as part of those styles. For all
-following sections, please review L</FORMATTING SPECIFICATIONS>.
+Once you're doing this, you may alter Concise output by adding new
+rendering styles, and by optionally adding callback routines which
+populate new variables, if such were referenced from those (just
+added) styles.
=head2 Example: Altering Concise Renderings
use B::Concise qw(set_style add_callback);
- set_style($your_format, $your_gotofmt, $your_treefmt);
+ add_style($yourStyleName => $defaultfmt, $gotofmt, $treefmt);
add_callback
( sub {
my ($h, $op, $format, $level, $stylename) = @_;
$h->{variable} = some_func($op);
- }
- );
- B::Concise::compile(@options)->();
+ });
+ $walker = B::Concise::compile(@options,@subnames,@subrefs);
+ $walker->();
=head2 set_style()
B<compile> accepts options as described above in L</OPTIONS>, and
arguments, which are either coderefs, or subroutine names.
-compile() constructs and returns a coderef, which when invoked, scans
-the optree, and prints the results to STDOUT. Once you have the
-coderef, you may change the output style; thereafter the coderef renders
-in the new style.
+It constructs and returns a $treewalker coderef, which when invoked,
+traverses, or walks, and renders the optrees of the given arguments to
+STDOUT. You can reuse this, and can change the rendering style used
+each time; thereafter the coderef renders in the new style.
B<walk_output> lets you change the print destination from STDOUT to
another open filehandle, or (unless you've built with -Uuseperlio)
into a string passed as a ref.
+ my $walker = B::Concise::compile('-terse','aFuncName', \&aSubRef); # 1
walk_output(\my $buf);
- my $walker = B::Concise::compile('-concise','funcName', \&aSubRef);
- print "Concise Banner for Functions: $buf\n";
- $walker->();
- print "Concise Rendering(s)?: $buf\n";
-
-For each subroutine visited by Concise, the $buf will contain a
-banner naming the function or coderef about to be traversed.
-Once $walker is invoked, it prints the actual renderings for each.
-
-To switch back to one of the standard styles like C<concise> or
-C<terse>, call C<set_style_standard>, or pass the style name into
-B::Concise::compile() (as done above).
+ $walker->(); # 1 renders -terse
+ set_style_standard('concise'); # 2
+ $walker->(); # 2 renders -concise
+ $walker->(@new); # 3 renders whatever
+ print "3 different renderings: terse, concise, and @new: $buf\n";
+
+When $walker is called, it traverses the subroutines supplied when it
+was created, and renders them using the current style. You can change
+the style afterwards in several different ways:
+
+ 1. call C<compile>, altering style or mode/order
+ 2. call C<set_style_standard>
+ 3. call $walker, passing @new options
+
+Passing new options to the $walker is the easiest way to change
+amongst any pre-defined styles (the ones you add are automatically
+recognized as options), and is the only way to alter rendering order
+without calling compile again. Note however that rendering state is
+still shared amongst multiple $walker objects, so they must still be
+used in a coordinated manner.

-=head1 Usage Philosophy
+=head1 Test Philosophy
2 platforms --> 2 reftexts: You want an accurate test, independent of
-which platform youre on. This is obvious in retrospect, but ..
+which platform you're on. So, two refdata properties, 'expect' and
+'expect_nt', carry renderings taken from threaded and non-threaded
+builds. This has several benefits:
-I started this with 1 reftext, and tried to use it to construct regexs
-for both platforms. This is extra complexity, trying to build a
-single regex for both cases makes the regex more complicated, and
-harder to get 'right'.
-
-Having 2 references also allows various 'tests', really explorations
-currently. At the very least, having 2 samples side by side allows
-inspection and aids understanding of optrees.
+ 1. native reference data allows closer matching by regex.
+ 2. samples can be eyeballed to grok t-nt differences.
+ 3. data can help to validate mkCheckRex() operation.
+ 4. can develop regexes which accomodate t-nt differences.
+ 5. can test with both native and cross+converted regexes.
Cross-testing (expect_nt on threaded, expect on non-threaded) exposes
differences in B::Concise output, so mkCheckRex has code to do some
name: The test name. May be augmented by a label, which is built from
important params, and which helps keep names in sync with whats being
-tested.

-Once selected, reftext massaged & convert into a Regex that accepts
-'good' concise renderings, with appropriate input variations, but is
-otherwize as strict as possible. For example, it should *not* match
-when opcode flags change, or when optimizations convert an op to an

matching 'nextstate(main 22 (eval 10):1)'. Besides, we are testing
for regressions, not for complete accuracy.
-The regex is unanchored, allowing success on simple expectations, such
-as one with a single 'print' opcode.
-
-=head2 complicating factors
-
-Note that %in may seem overly complicated, but it's needed to allow
-mkCheckRex to better support selftest,
-
-The emerging complexity is that mkCheckRex must choose which refdata
-to use as a template for the regex being constructed. This feels like
-selection mechanics being duplicated.
+The regex is anchored by default, but can be suppressed with
+'noanchors', allowing 1-liner tests to succeed if opcode is found.
-=head1 FEATURES, BUGS, ENHANCEMENTS
+=head1 TEST DEVELOPMENT SUPPORT
-Hey, they're the same thing now, modulo heisen-phase-shifting, and the
-probe used to observe them.
+This optree regression testing framework needs tests in order to find
+bugs. To that end, OptreeCheck has support for developing new tests,
+according to the following model:
-=head1 Test Data
+ 1. write a set of sample code into a single file, one per
+ paragraph. f_map and f_sort in ext/B/t/ are examples.
-Test cases were recently doubled, by adding a 2nd ref-data property;
-expect and expect_nt carry renderings taken from threaded and
-non-threaded builds. This addition has several benefits:
+ 2. run OptreeCheck as a program on the file
- 1. native reference data allows closer matching by regex.
- 2. samples can be eyeballed to grok t-nt differences.
- 3. data can help to validate mkCheckRex() operation.
- 4. can develop code to smooth t-nt differences.
- 5. can test with both native and cross+converted rexes
+ ./perl -Ilib ext/B/t/OptreeCheck.pm -w ext/B/t/f_map
+ ./perl -Ilib ext/B/t/OptreeCheck.pm -w ext/B/t/f_sort
-Enhancements:
+ gentest reads the sample code, runs each to generate a reference
+ rendering, folds this rendering into an optreeCheck() statement,
+ and prints it to stdout.
-Tests should specify both 'expect' and 'expect_nt', making the
-distinction now will allow a range of behaviors, in escalating
-thoroughness. This variable is called provenance, indicating where
-the reftext came from.
+ 3. run the output file as above, redirect to files, then rerun on
+ same build (for sanity check), and on thread-opposite build. With
+ editor in 1 window, and cmd in other, it's fairly easy to cut-paste
+ the gots into the expects, easier than running step 2 on both
+ builds then trying to sdiff them together.
-build_only: tests which dont have the reference-sample of the
-right provenance will be skipped. NO GOOD.
+=head1 TODO
-prefer_expect: This is implied standard, as all tests done thus far
-started here. One way t->nt conversions is done, based upon Config.
+There's a considerable amount of cruft in the whole arg-handling setup.
+I'll replace / strip it before 5.10
-activetest: do cross-testing when test-case has both, ie also test
-'expect_nt' references on threaded builds. This is aggressive, and is
-intended to seek out t<->nt differences. if mkCheckRex knows
-provenance and Config, it can do 2 way t<->nt conversions.
+Treat %in as a test object, interwork better with Test::*
-activemapping: This builds upon activetest by controlling whether
-t<->nt conversions are done, and allows simpler verification that each
-conversion step is indeed necessary.
+Refactor mkCheckRex() and selfTest() to isolate the selftest,
+crosstest, etc selection mechanics.
-pedantic: this fails if tests dont have both, whereas above doesn't care.
+improve retry, retrydbg, esp. it's control of eval "use re debug".
+This seems to work part of the time, but isn't stable enough.
