From: Rafael Garcia-Suarez Date: Wed, 20 Sep 2006 15:22:22 +0000 (+0000) Subject: prototype() wasn't working to get the prototype of optional core X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=5458a98a294861b5056e599fe9e1cbe7c1f7b678;p=p5sagit%2Fp5-mst-13.2.git prototype() wasn't working to get the prototype of optional core keywords (like say, err, given.) Fix this by adding a parameter to Perl_keyword to always get the keyword number, even if the feature isn't in effect. p4raw-id: //depot/perl@28874 --- diff --git a/embed.fnc b/embed.fnc index 63e9e8f..7320b9f 100644 --- a/embed.fnc +++ b/embed.fnc @@ -395,7 +395,7 @@ ApR |bool |is_utf8_punct |NN const U8 *p ApR |bool |is_utf8_xdigit |NN const U8 *p ApR |bool |is_utf8_mark |NN const U8 *p p |OP* |jmaybe |NN OP* arg -pP |I32 |keyword |NN const char* d|I32 len +pP |I32 |keyword |NN const char* d|I32 len|bool all_keywords Ap |void |leave_scope |I32 base p |void |lex_end p |void |lex_start |NN SV* line diff --git a/embed.h b/embed.h index fa43f4b..4ae5706 100644 --- a/embed.h +++ b/embed.h @@ -2573,7 +2573,7 @@ #define is_utf8_mark(a) Perl_is_utf8_mark(aTHX_ a) #ifdef PERL_CORE #define jmaybe(a) Perl_jmaybe(aTHX_ a) -#define keyword(a,b) Perl_keyword(aTHX_ a,b) +#define keyword(a,b,c) Perl_keyword(aTHX_ a,b,c) #endif #define leave_scope(a) Perl_leave_scope(aTHX_ a) #ifdef PERL_CORE diff --git a/perl_keyword.pl b/perl_keyword.pl index b2e9e34..ab9559c 100644 --- a/perl_keyword.pl +++ b/perl_keyword.pl @@ -67,7 +67,7 @@ print <= 7) { const char * const s = SvPVX_const(TOPs); if (strnEQ(s, "CORE::", 6)) { - const int code = keyword(s + 6, SvCUR(TOPs) - 6); + const int code = keyword(s + 6, SvCUR(TOPs) - 6, 1); if (code < 0) { /* Overridable. */ #define MAX_ARGS_OP ((sizeof(I32) - 1) * 2) int i = 0, n = 0, seen_question = 0; @@ -397,7 +397,7 @@ PP(pp_prototype) char str[ MAX_ARGS_OP * 2 + 2 ]; /* One ';', one '\0' */ if (code == -KEY_chop || code == -KEY_chomp - || code == -KEY_exec || code == -KEY_system) + || code == -KEY_exec || code == -KEY_system || code == -KEY_err) goto set; while (i < MAXO) { /* The slow way. */ if (strEQ(s + 6, PL_op_name[i]) diff --git a/proto.h b/proto.h index a957f32..87daeeb 100644 --- a/proto.h +++ b/proto.h @@ -1007,7 +1007,7 @@ PERL_CALLCONV bool Perl_is_utf8_mark(pTHX_ const U8 *p) PERL_CALLCONV OP* Perl_jmaybe(pTHX_ OP* arg) __attribute__nonnull__(pTHX_1); -PERL_CALLCONV I32 Perl_keyword(pTHX_ const char* d, I32 len) +PERL_CALLCONV I32 Perl_keyword(pTHX_ const char* d, I32 len, bool all_keywords) __attribute__pure__ __attribute__nonnull__(pTHX_1); diff --git a/t/op/cproto.t b/t/op/cproto.t index 3f3e871..a02ab46 100644 --- a/t/op/cproto.t +++ b/t/op/cproto.t @@ -7,7 +7,7 @@ BEGIN { } BEGIN { require './test.pl'; } -plan tests => 234; +plan tests => 238; while () { chomp; @@ -68,7 +68,7 @@ endpwent () endservent () eof (;*) eq ($$) -err unknown +err () eval undef exec undef exists undef @@ -109,6 +109,7 @@ getservbyport ($$) getservent () getsockname (*) getsockopt (*$$) +given undef glob undef gmtime (;$) goto undef @@ -186,6 +187,7 @@ rewinddir (*) rindex ($$;$) rmdir (;$) s undef +say (;*@) scalar undef seek (*$$) seekdir (*$) @@ -220,6 +222,7 @@ sprintf ($@) sqrt (;$) srand (;$) stat (*) +state undef study undef sub undef substr ($$;$$) @@ -256,6 +259,7 @@ wait () waitpid ($$) wantarray () warn (@) +when undef while undef write (;*) x unknown diff --git a/toke.c b/toke.c index b097e39..f5aa5d1 100644 --- a/toke.c +++ b/toke.c @@ -1275,7 +1275,7 @@ S_force_word(pTHX_ register char *start, int token, int check_keyword, int allow (allow_initial_tick && *s == '\'') ) { s = scan_word(s, PL_tokenbuf, sizeof PL_tokenbuf, allow_pack, &len); - if (check_keyword && keyword(PL_tokenbuf, len)) + if (check_keyword && keyword(PL_tokenbuf, len, 0)) return start; start_force(PL_curforce); if (PL_madskills) @@ -2514,7 +2514,7 @@ S_intuit_more(pTHX_ register char *s) while (isALPHA(*s)) *d++ = *s++; *d = '\0'; - if (keyword(tmpbuf, d - tmpbuf)) + if (keyword(tmpbuf, d - tmpbuf, 0)) weight -= 150; } if (un_char == last_un_char + 1) @@ -2600,7 +2600,7 @@ S_intuit_method(pTHX_ char *start, GV *gv, CV *cv) PL_expect = XREF; return *s == '(' ?
