* Implement the fc keyword and the \F string escape.Brian Fraser2012-01-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | Along with the simple_casefolding and full_casefolding features. fc() stands for foldcase, a sort of pseudo case (like lowercase), which is used to implement Unicode casefolding. It maps a string to a form where all case differences are erased, so it's a locale-independent way of checking if two strings are the same, regardless of case. This functionality was, and still is, available through the regular expression engine -- /i matches would use casefolding internally. The fc keyword merely exposes this for easier access. Previously, one could attempt to case-insensitively test two strings for equality by doing lc($a) eq lc($b) But that might get you wrong results, for example in the case of \x{DF}, LATIN SMALL LETTER SHARP S.
* [perl #80628] __SUB__Father Chrysostomos2011-11-221-1/+2
| | | | | After much alternation, altercation and alteration, __SUB__ is finally here.
* regen/opcode.pl: generate OP_IS_DIRHOP, use in gv.cJim Cromie2011-09-091-3/+7
| | | | | | | Generate OP_IS_DIRHOP like other OP_IS_* macros, use in gv.c:Perl_gv_add_by_type(). Modifies 'F' operand type to 'DF'. This yields a micro-optimization.
* implement OP_IS_NUMCOMPARE like other OP_IS macrosJim Cromie2011-09-091-0/+3
| | | | | | | other macros are written by regen/opcode.pl into opnames.h Generate OP_IS_NUMCOMPARE the same way, and get a micro-optimization. Adds a new 'S<' operand type for the numeric comparison ops. Needs make regen.
* Add coreargs opFather Chrysostomos2011-08-181-1/+2
| | | | &CORE::foo subs will use this operator for sorting out @_.

* Split OP_AELEMFAST_LEX out from OP_AELEMFAST.Nicholas Clark2011-06-121-1/+2
| | | | | | | | | | | | | 6a077020aea1c5f0 extended the OP_AELEMFAST optimisation to lexical arrays. Previously OP_AELEMFAST was only used as an optimisation for OP_GV, which is a PADOP/SVOP. However, by reusing the same opcode, and signalling (pad) lexical vs package, it introduced a myriad of special cases, because OP_PADAV is a BASEOP (not a PADOP), whilst OP_AELEMFAST is a PADOP/SVOP (which is larger). Using two OP numbers allows each variant to have the correct OP flags in PL_opargs. Both can continue to share the same C code.
* Move all the generated file header printing into read_only_top()Nicholas Clark2011-01-231-5/+4
| | | | | | | | | Previously all the scripts in regen/ had code to generate header comments (buffer-read-only, "do not edit this file", and optionally regeneration script, regeneration data, copyright years and filename). This change results in some minor reformatting of header blocks, and standardises the copyright line as "Larry Wall and others".
* Extract the opcode data from regen/opcode.pl into regen/opcodesNicholas Clark2011-01-091-1/+1
| | | | | Whilst it is possible to open regen/opcode.pl and parse it to find the __END__ token, it's not the cleanest approach.
* Remove OP_phoney_{IN,OUT}PUT_ONLY, as they are no longer used or supported.Nicholas Clark2010-12-281-3/+0

* Add transr op typeFather Chrysostomos2010-11-021-1/+2
| | | | | for the upcoming y///r feature. There are not enough flag bits, hence the extra type.
* Allow push/pop/keys/etc to act on referencesDavid Golden2010-10-311-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All built-in functions that operate directly on array or hash containers now also accept hard references to arrays or hashes: |----------------------------+---------------------------| | Traditional syntax | Terse syntax | |----------------------------+---------------------------| | push @$arrayref, @stuff | push $arrayref, @stuff | | unshift @$arrayref, @stuff | unshift $arrayref, @stuff | | pop @$arrayref | pop $arrayref | | shift @$arrayref | shift $arrayref | | splice @$arrayref, 0, 2 | splice $arrayref, 0, 2 | | keys %$hashref | keys $hashref | | keys @$arrayref | keys $arrayref | | values %$hashref | values $hashref | | values @$arrayref | values $arrayref | | ($k,$v) = each %$hashref | ($k,$v) = each $hashref | | ($k,$v) = each @$arrayref | ($k,$v) = each $arrayref | |----------------------------+---------------------------| This allows these built-in functions to act on long dereferencing chains or on the return value of subroutines without needing to wrap them in C<@{}> or C<%{}>: push @{$obj->tags}, $new_tag; # old way push $obj->tags, $new_tag; # new way for ( keys %{$hoh->{genres}{artists}} ) {...} # old way for ( keys $hoh->{genres}{artists} ) {...} # new way For C<push>, C<unshift> and C<splice>, the reference will auto-vivify if it is not defined, just as if it were wrapped with C<@{}>. Calling C<keys> or C<values> directly on a reference gives a substantial performance improvement over explicit dereferencing. For C<keys>, C<values>, C<each>, when overloaded dereferencing is present, the overloaded dereference is used instead of dereferencing the underlying reftype. Warnings are issued about assumptions made in the following three ambiguous cases: (a) If both %{} and @{} overloading exists, %{} is used (b) If %{} overloading exists on a blessed arrayref, %{} is used (c) If @{} overloading exists on a blessed hashref, @{} is used

* Move the boolkeys op to the group of hash ops.Nicholas Clark2009-10-151-225/+225
| | | | This breaks binary compatibility.
* Optimise if (%foo) to be faster than if(keys %foo)demerphq2009-10-151-1/+2
| | | | | | | | | | | Thread was "[PATCH] Make if (%hash) {} act the same as if (keys %hash) {}" http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-11/msg00432.html but the implementation evolved from the approach described in the subject, to instead add a new opcode pp_boolkeys, to exactly preserve the existing behaviour. Various conflicts with the passage of time resolved, 'register' removed, and a $VERSION bump.

* Make state $zok = slosh(); behave as the Perl 6 design with an implicitNicholas Clark2007-09-061-2/+3
| | | | | | | | | | | | | | | START block. First time through, call slosh() and assign to $zok. Subsequently neither call slosh() nor assign to $zok. Adds a new op ONCE to control the conditonal call and assign. No change to list context, so state ($zok) = slosh() and (state $zok) = ... etc will still repeatedly evaluate and assign. [Can't fix that before 5.10] Use as an RVALUE is as Larry's design - my $boff = state $zok = ...; will evaluate, assign and return first time, and subsequently act as if it were written my $boff = $zok; FIXME - state $zok = ...; won't deparse - I believe op->op_last isn't being correctly set on the sassign, but I don't know how to fix this.
