* index/value array slice operationRuslan Zakirov2013-09-131-0/+1
| | | | | | kvaslice operator that imlements %a[0,2,4] syntax which result in list of index/value pairs. Implemented in consistency with "key/value hash slice" operator.
* key/value hash slice operationRuslan Zakirov2013-09-131-0/+1
| | | | | | kvhslice operator that implements %h{1,2,3,4} syntax which returns list of key value pairs rather than just values (regular slices).
* add padrange opDavid Mitchell2012-11-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This single op can, in some circumstances, replace the sequence of a pushmark followed by one or more padsv/padav/padhv ops, and possibly a trailing 'list' op, but only where the targs of the pad ops form a continuous range. This is generally more efficient, but is particularly so in the case of void-context my declarations, such as: my ($a,@b); Formerly this would be executed as the following set of ops: pushmark pushes a new mark padsv[$a] pushes $a, does a SAVEt_CLEARSV padav[@b] pushes all the flattened elements (i.e. none) of @a, does a SAVEt_CLEARSV list pops the mark, and pops all stack elements except the last nextstate pops the remaining stack element It's now: padrange[$a..@b] does two SAVEt_CLEARSV's nextstate nothing needing doing to the stack Note that in the case above, this commit changes user-visible behaviour in pathological cases; in particular, it has always been possible to modify a lexical var *before* the my is executed, using goto or closure tricks. So in principle someone could tie an array, then could notice that FETCH is no longer being called, e.g. f(); my ($s, @a); # this no longer triggers two FETCHES sub f { tie @a, ...; push @a, 1,2; } But I think we can live with that. Note also that having a padrange operator will allow us shortly to have a corresponding SAVEt_CLEARPADRANGE save type, that will replace multiple individual SAVEt_CLEARSV's.
* Add clonecv op typeFather Chrysostomos2012-09-151-0/+1
| | | | | | This will be used for cloning a ‘my’ sub on scope entry. I was going to use pp_padcv for this, but it would end up having a top-level if/else.
* Add introcv op typeFather Chrysostomos2012-09-151-0/+1
| | | | | This will be used for introducing ‘my’ subs on scope entry, by turning off the stale flag.

* Banish boolkeysFather Chrysostomos2012-08-251-1/+0
| | | | | | | | | | | | | | Since 6ea72b3a1, rv2hv and padhv have had the ability to return boo- leans in scalar context, instead of bucket stats, if flagged the right way. sub { %hash || ... } is optimised to take advantage of this. If the || is in unknown context at compile time, the %hash is flagged as being maybe a true boolean. When flagged that way, it returns a bool- ean if block_gimme() returns G_VOID. If rv2hv and padhv can already do this, then we don’t need the boolkeys op any more. We can just flag the rv2hv to return a boolean. In all the cases where boolkeys was used, we know at compile time that it is true boolean context, so we add a new flag for that.
* Implement the fc keyword and the \F string escape.Brian Fraser2012-01-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | 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 Chrysostomos2011-11-221-0/+1
| | | | | After much alternation, altercation and alteration, __SUB__ is finally here.
* Merge postinc and postdecFather Chrysostomos2011-09-161-1/+0
| | | | They were nearly identical.
* Merge preinc and postincFather Chrysostomos2011-09-161-1/+0
| | | | | They are almost identical. This gives the compiler less code to digest.
* Add coreargs opFather Chrysostomos2011-08-181-0/+1
| | | | &CORE::foo subs will use this operator for sorting out @_.
* Move all the generated file header printing into read_only_top()Nicholas Clark2011-01-231-3/+3
| | | | | | | | | 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".
* Merge the implementations of {end,set}{gr,pw}ent with endhostent.Nicholas Clark2011-01-101-4/+0
| | | | | Unlike set{host,net,proto,serv}ent, set{gr,pw}ent don't have stayopen parameter, hence their "signature" is the same as the ent*ent functions.
* Merge the implementations of pp_s{host,net,proto,serv}ent.Nicholas Clark2011-01-101-3/+0
|
* Merge the implementations of pp_e{host,net,proto,serv}ent.Nicholas Clark2011-01-101-3/+0
| | | | | | | PL_op_desc[] rather than PL_op_name(), as the OPs are internally named e*ent, but implement the ent*ent functions, and when unimplemented report themselves using the function name. No need for OP_DESC(), as the switch statement means that we can't encounter OP_CUSTOM.
* Rename pp_send to pp_syswrite, making send an alias for syswrite.Nicholas Clark2011-01-091-1/+1
| | | | | Previously syswrite was an alias for send. However, syswrite is always available, whereas send is not implemented if HAS_SOCKET is not defined.
* regen/opcode.pl should only generate prototypes for pp_* functions that exist.Nicholas Clark2011-01-091-91/+2
| | | | | | | It now generates prototypes for all functions that implement OPs. Hence Perl_unimplemented_op no longer needs a special-case prototype. As it is now generating a prototype for Perl_do_kv, no need for regen/embed.pl to duplicate this. Convert the last two users of the macro do_kv() to Perl_do_kv(aTHX).
* Generate pp_* prototypes in pp_proto.h, and remove pp.symNicholas Clark2011-01-091-2/+373
| | | | | | | | | | | Eliminate the #define pp_foo Perl_pp_foo(pTHX) macros, and update the 13 locations that relied on them. regen/opcode.pl now generates prototypes for the PP functions directly, into pp_proto.h. It no longer writes pp.sym, and regen/embed.pl no longer reads this, removing the only ordering dependency in the regen scripts. opcode.pl is now responsible for prototypes for pp_* functions. (embed.pl remains responsible for ck_* functions, reading from regen/opcodes)
* Move OP prototypes from pp_proto.h to proto.hNicholas Clark2010-09-271-414/+2
| | | | | | | | | | | | Make embed.pl fully responsible for generating prototypes and embedding macros for pp_* and ck_* functions, placing them in embed.h and proto.h opcode.pl no longer generates pp_proto.h Remove the (effectively) duplicate explicit entries for (all but 2) ck_* functions from embed.fnc We can't actually remove pp_proto.h from the distribution *yet*, as ExtUtils::MM_Unix and ExtUtils::MM_VMS have hardcoded lists of the installed headers. Once this is resolved, we can.
* Move the boolkeys op to the group of hash ops.Nicholas Clark2009-10-151-1/+1
| | | | This breaks binary compatibility.
* Optimise if (%foo) to be faster than if(keys %foo)demerphq2009-10-151-0/+1
| | | | | | | | | | | 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 Clark2007-09-061-0/+1
| | | | | | | | | | | | | | | 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. This change may be backed out before 5.10. p4raw-id: //depot/perl@31798
