* utf8.c: Add _flags version of to_utf8_fold()Karl Williamson2011-05-031-2/+2
| | | | | | | | | | And also to_uni_fold(). The flag allows retrieving either simple or full folds. The interface is subject to change, so these are marked experimental and their names begin with underscore. The old versions are turned into macros calling the new versions with the correct extra parameter.
* handy.h: isIDFIRST_utf8() changed to use XIDStartKarl Williamson2011-02-171-0/+2
| | | | | | | | | | Previously this used a home-grown definition of an identifier start, stemming from a bug in some early Unicode versions. This led to some problems, fixed by #74022. But the home-grown solution did not track Unicode, and allowed for characters, like marks, to begin words when they shouldn't. This change brings this macro into compliance with Unicode going-forward.
* exporting a static function doesnt workKarl Williamson2011-02-141-2/+0

* foldEQ_utf8: Add version with flags parameterKarl Williamson2011-02-141-1/+1
| | | | | The parameter doesn't do anything yet. The old version becomes a macro calling the new version with 0 as the flags.
* regcomp.c: Put two static functions in embed.fncKarl Williamson2011-02-141-0/+2

* Move grok_bslash_c to dquote.c and make staticKarl Williamson2011-02-091-1/+1
| | | | No other changes were made
* Move grok_blsash_o and make staticKarl Williamson2011-02-091-1/+1
| | | | | | This function is only used in the same places as dquote_static.c is used, so move it there, and we won't have to worry about changing its API will break something. No other changes made

* _swash_inversion_hash Rmv X from embed, add constKarl Williamson2011-02-021-1/+0
| | | | This shouldn't be called from XS code.
* Change close_and_rename() to read_only_bottom_close_and_rename()Nicholas Clark2011-01-231-0/+1
| | | | | | | | | | All users of close_and_rename() were printing out the appropriate "ex: set ro:" string to the file handle immediately before closing it. So move that into the common function and rename it to reflect what it now does. [Except overload.pl, which should have been, given that it calls read_only_top()] Print a newline above the "ex: set ro:" line. This removes many newlines from the regen scripts, but does add newlines to a couple of generated files.
* Move all the generated file header printing into read_only_top()Nicholas Clark2011-01-231-5/+5
| | | | | | | | | 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".
* Generate pp_* prototypes in pp_proto.h, and remove pp.symNicholas Clark2011-01-091-1/+1
| | | | | | | | | | | 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)
* recursive-descent expression parsingZefram2010-12-111-0/+4
| | | | | | New API functions parse_fullexpr(), parse_listexpr(), parse_termexpr(), and parse_arithexpr(), to parse an expression at various precedence levels.

* Add Perl_foldEQ_latin1()Karl Williamson2010-11-281-0/+1
| | | | | | | | | | This function compares two non-utf8 strings to see if they are equivalent without regards to case differences. It does not work nor check for three problematic code points that require special handling: MICRO_SIGN, LATIN_SMALL_LETTER_SHARP_S, and LATIN_SMALL_LETTER_Y_WITH_DIAERESIS. make regen required
* [perl #78908] Reinstate mod for one more stable releaseFather Chrysostomos2010-11-261-0/+1
|
* Explicitly export Perl_sv_compile_2op_is_broken(), for ext/re.Nicholas Clark2010-11-241-0/+1
| | | | | Frustratingly, because regcomp.c is also compiled as ext/re/re_comp.c, anything it needs has to be exported. So this has to be X. I'd rather it wasn't.
* hv_undef .= _flagsFather Chrysostomos2010-11-201-1/+1
| | | | | | | Add flags param to hv_undef. There is no mathom, as the changes that this will support are by no means suitable for maint.
* Improve custom OP support.Ben Morrow2010-11-141-0/+2
| | | | | | | | | | | | | | | | | Change the custom op registrations from two separate hashes to one hash holding structure pointers, and add API functions to register ops and look them up. This will make it easier to add new properties of custom ops in the future. Copy entries across from the old hashes where necessary, to preserve compatibility. Add two new properties, in addition to the already-existing 'name' and 'description': 'class' and 'peep'. 'class' is one of the OA_*OP constants, and allows B and other introspection mechanisms to work with custom ops that aren't BASEOPs. 'peep' is a pointer to a function that will be called for ops of this type from Perl_rpeep. Adjust B.xs to take account of the new properties, and also to give custom ops their registered name rather than simply 'custom'.
* Add Perl_bytes_cmp_utf8() to compare character sequences in different encodingsNicholas Clark2010-11-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Convert sv_eq_flags() and sv_cmp_flags() to use it. Previously, to compare two strings of characters, where was was in UTF-8, and one was not, you had to either: 1: Upgrade the second to UTF-8 2: Compare the resulting octet sequence 3: Free the temporary UTF-8 string or: 1: Attempt to downgrade the first to bytes. If it can't be, they aren't equal 2: Else compare the resulting octet sequence 3: Free the temporary byte string Which for the general case involves a malloc()/free() and at least two O(n) scans per comparison. Whereas this approach has no allocation, a single O(n) scan, which terminates as early as the best case for the second approach.
* utf8.c: Add function to create inversion of swashKarl Williamson2010-11-071-0/+1
| | | | | | | | | | | | This adds _swash_inversion_hash() which takes a mapping swash and returns a hash that is the inverse relation. That is, given a code point, it allows quick lookup of all code points that map to it. The function is not for public use, as it will likely be revised, so is not in the public API, and it's name begins with underscore. It does not deal with multi-char mappings at this time, nor other swash complications.
* Add Perl_amagic_deref_call() to implement the bulk of tryAMAGICunDEREF_var().Nicholas Clark2010-11-031-0/+1
| | | | | | | | | This removes around 300 bytes of object code from each place it was previously inlined. It also provides a better interface - quite a lot of the core currently bodges things by creating a local variable C<SV **sp = &sv> to use the macro. Change the XS::APItest wrapper to amagic_deref_call().
* new API functions op_scope and op_lvalueZefram2010-10-261-1/+2
| | | | | | The function scope() goes into the API as op_scope(), and mod() goes into the API as op_lvalue(). Both marked experimental, because their behaviour is a little quirky and not trivially dequirkable.
* add CvSTASH_set() macro and make CvSTASH() rvalue onlyZefram2010-10-251-0/+1
| | | | | | Now that CvSTASH requires backreference bookkeeping, stop people from directly assigning to it (by using CvSTASH() as an lvalue), and instead force them to use CvSTASH_set().
* function to parse isolated labelZefram2010-10-251-0/+1
| | | | | | | New API function parse_label() parses a label, separate from statements. If a label has not already been lexed and queued up, it does not use yylex(), but parses the label itself at the character level, to avoid unwanted lexing past an absent optional label.
* function to parse unlabelled statementZefram2010-10-251-0/+1
| | | | | New API function parse_barestmt() parses a pure statement, with no label, and returns just the statement's core ops, not attaching a state op.
* full API for cop hint hashesZefram2010-10-211-4/+8
| | | | | | | | | | | | | Expose cop hint hashes as a type COPHH, with a cophh_* API which is a macro layer over the refcounted_he_* API. The documentation for cophh_* describes purely API-visible behaviour, whereas the refcounted_he_* documentation describes the functions mainly in terms of the implementation. Revise the cop_hints_* API, using the flags parameter consistently and reimplementing in terms of cophh_*. Use the cophh_* and cop_hints_* functions consistently where appropriate. [Modified by the committer to update two calls to Perl_refcounted_he_fetch recently added to newPMOP.]
* function to parse Perl code blockZefram2010-10-211-0/+1
| | | | | New API function parse_block() parses a code block, including surrounding braces. The block is a lexical scope, but not inherently a dynamic scope.
* add lex_start to the APIZefram2010-10-211-0/+1
| | | | | lex_start() is added to the API, marked experimental, and documented. It also gains a flags parameter for foreseeable future use.
* remove redundant lex_endZefram2010-10-211-1/+0
| | | | | | | The lex_end() function is redundant, because the lexer context object is actually finalised by parser_free(), triggered by the save stack. The lex_end() function has historically been empty, except when the PL_doextract global was being misused to store lexer state.
* embed.pl -> regen/embed.plFather Chrysostomos2010-10-131-2/+2
| | | | so newcomers can find it more easily
* Add LINKLIST to the API.Ben Morrow2010-10-121-0/+1
| | | | | Also rename the underlying function to op_linklist, to match the other API op functions.
* APIify op list constructorsZefram2010-10-121-0/+3
| | | | | | Put into the API op_append_elem, op_prepend_elem, and op_append_list. All renamed from op_-less internal names. Parameter types for op_append_list changed to match the rest of the op API and avoid some casting.
* plugin mechanism to rewrite calls to a subroutineZefram2010-10-101-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | New magic type PERL_MAGIC_checkcall attaches a function to a CV, which will be called as the second half of the op checker for an entersub op calling that CV. Default state, in the absence of this magic, is to process the CV's prototype if it has one, or apply list context to all the arguments if not. New API functions cv_get_call_checker() and cv_set_call_checker() provide a clean interface to this facility, hiding the internal use of magic. Expose in the API the new functions rv2cv_op_cv(), ck_entersub_args_list(), ck_entersub_args_proto(), and ck_entersub_args_proto_or_list(), which are meaningful segments of standard entersub op checking and are likely to be useful in plugged-in call checker functions. Expose new API function op_contextualize(), which is a public interface to the internal scalar()/list()/scalarvoid() functions. This API is likely to be required in most plugged-in call checker functions. Incidentally add new function mg_free_type(), in the API, which will remove magic of one type from an SV. (mg_free() removes all magic, and there isn't anything else more selective.)
* Convert the implementation of XS_APIVERSION_BOOTCHECK to a function.Nicholas Clark2010-10-081-0/+1
| | | | | | The previous macro generated over .5K of object code. This is in every shared object, and is only called once. Hence this change increases the perl binary by about .5K (once), to save .5K for every XS module loaded.
* Convert the implementation of XS_VERSION_BOOTCHECK to a function from a macro.Nicholas Clark2010-10-071-0/+1
| | | | | | The macro expansion generates over 1K of object code. This is in every shared object, and is only called once. Hence this change increases the perl binary by about 1K (once), to save 1K for every XS module loaded.
* [PATCH] function to parse Perl statement sequenceZefram2010-10-041-0/+1
| | | | | New API function parse_stmtseq() parses a sequence of statements, up to closing brace or EOF.
* add stray save_* functions to the APIZefram2010-10-041-0/+2

* Sort embed.fnc by CPP macro and then function name, before generating files.Nicholas Clark2010-09-301-452/+452
| | | | | Additionally, sort embed.h by public API, then core-or-ext, and finally core only. This reduces the number of #if/#endif pairs in embed.h and proto.h
* systematically provide pv/pvn/pvs/sv quartetsZefram2010-09-281-0/+4
| | | | | Anywhere an API function takes a string in pvn form, ensure that there are corresponding pv, pvs, and sv APIs.
* [perl #76814] FETCH called twice - !Father Chrysostomos2010-09-241-1/+1
| | | | | | This fixes ! by changing sv_2bool to sv_2bool_flags (with a macro wrapper) and adding SvTRUE_nomg. It also corrects the docs that state incorrectly that SvTRUE does not handle magic.
* [perl #76814] FETCH called twice - string comparison opsFather Chrysostomos2010-09-241-2/+4
| | | | | | This patch changes sv_eq, sv_cmp, sv_cmp_locale and sv_collxfrm to _flags forms, with macros under the old names for sv_eq and sv_collxfrm, but functions for sv_cmp* since pp_sort.c needs them.
* Run perl regen.pl after removing regcurly from embed.fnc.Andy Dougherty2010-09-221-1/+0
| | | | | | | | Since regcurly is now a static inline function, it no longer needs to appear in embed.fnc. embed.pl doesn't quite have the right flags to deal with static inline functions, so I just removed regcurly entirely. It's not for embedding or exporting anyway.
* Back out the mauve module and related changesFlorian Ragwitz2010-09-161-1/+0
| | | | | | | | | | | | | | | | | | | | | It's was intended as a temporary namespace only, and we really don't want to ship it in any release until we've figured out what it should really look like. This reverts commit 05c0d6bbe3ec5cc9af99d105b8648ad02ed7cc95, "add sv_reftype_len() and make sv_reftype() be a wrapper for it" commit 792477b9c2e4c75cb03d07bd6d25dc7e1fdf448e, "create the "mauve" temporary namespace for things like reftype" commit 8df6b97c1de8326d50ac9c8cae4bf716393b45bb, "mauve.t needs access to %Config, make sure it's available" commit cfe9162d0d593cd12a979c73df82c7509b324343, "use more efficient sv_reftype_len() interface" and commit 47b13905e23c2a72acdde8bb4669e25e5eaefec4 "add more tests to lib/mauve.t so it tests also that mauve::reftype can return "LVALUE"" There's a `mauve' branch still containing all the code for the temporary mauve namespace. That should be used to work on it until it's mostly ready to be released, and only then merged to blead. Alternatively, it should be deleted if another way to provide mauve's features in the core is found.
