* Macros to en/disable blockhook entries.Ben Morrow2010-07-151-1/+23
| | | | | This allows the individual callbacks to be switched on and off as necessary, without removing the entry from PL_blockhooks.
* Document the blockhook functions and macros.Ben Morrow2010-07-121-0/+24
|
* Macroify the block_hooks structure.Ben Morrow2010-07-121-5/+23
| | | | | Add a flags member, so it can be extended later if necessary. Add a bhk_eval member, called from doeval to catch requires and string evals.
* Generic hooks into Perl_block_{start,end}.Ben Morrow2010-07-121-0/+26
| | | | | | | | | | These take the form of a vtable pushed onto the new PL_blockhooks array. This could probably do with a API around it later. Separate pre_end and post_end hooks are needed to capture globals before the stack is unwound (like needblockscope in the existing code). The intention is that once a vtable is installed it never gets removed, so where necessary extensions using this will need to use a hinthv element to determine whether to do anything or not.
* Link from GIMME_V to perlcall for a usage example.Shlomi Fish2010-05-251-1/+1
| | | | | | Added a link from the GIMME_V entry to perlcall for a usage example. Signed-off-by: David Golden <dagolden@cpan.org>
* add OPpDEREFed flag to avoid double mg_get()David Mitchell2010-05-251-0/+2
| | | | | | | | | | | | | The previous commit made various ops such as rv2av unconditionally do an SvGETMAGIC(). Under some circumstances this could cause a double mg_get() (and hence double FETCH etc). In particular, when the proceeding op was something like aelem with OPpDEREF, the aelem would call vivify_ref(), which would call magic. So in peep(), mark OP_RV2[SAH]V ops with the new OPpDEREFed flag if the preceding op was OPpDEREF. Then use this flag to avoid a second dose of magic. Note that RV2GV probably needs this flag too, but there weren't any spare private flag bits left for that op (I think).
* Add s///r (non-destructive substitution).David Caldwell2010-05-221-0/+2
| | | | | | | | | | | | | | | | This changes s/// so that it doesn't act destructively on its target. Instead it returns the result of the substitution (or the original string if there was no match). In addition this patch: * Adds a new warning when s///r happens in void context. * Adds a error when you try to use s///r with !~ * Makes it so constant strings can be bound to s///r with =~ * Adds documentation. * Adds some tests. * Updates various debug code so it knows about the /r flag. * Adds some new 'r' words to B::Deparse.

* Add a macro MUTABLE_PTR(p), which on (non-pedantic) gcc will not castNicholas Clark2008-10-271-2/+2
| | | | | | | | | | away const, returning a void *. Add MUTABLE_SV(sv) which uses this, and replace all (SV *) casts either with MUTABLE_SV(sv), or (const SV *). This probably still needs some work - assigning to SvPVX() and SvRV() is now likely to generate a casting error. The core doesn't do this. But as-is it's finding bugs that can be fixed. p4raw-id: //depot/perl@34605
