Hey all,
I am trying to add new opening and closing tags (<?php - ?>) mainly for
testing functionality and curiosity. I believe, after 5 hours, that I have
tracked down the location of where this is defined,
Zend/zend_language_scanner.l. Here is a snippet of what was originally
there:
<INITIAL>"<?php"([ \t]|{NEWLINE}) {
zendlval->value.str.val = yytext; /* no copying - intentional */
zendlval->value.str.len = yyleng;
zendlval->type = IS_STRING;
HANDLE_NEWLINE(yytext[yyleng-1]);
BEGIN(ST_IN_SCRIPTING);
return T_OPEN_TAG;
}
What I have done is simply this:
<INITIAL>"<@abc"([ \t]|{NEWLINE}) {
zendlval->value.str.val = yytext; /* no copying - intentional */
zendlval->value.str.len = yyleng;
zendlval->type = IS_STRING;
HANDLE_NEWLINE(yytext[yyleng-1]);
BEGIN(ST_IN_SCRIPTING);
return T_OPEN_TAG;
}
As for the closing tag, I have made the appropriate changes shown below.
<ST_ONE_LINE_COMMENT>"?>"|"%>"|"@>" {
if (CG(asp_tags) || yytext[yyleng-2] != '%') { /* asp comment? */
zendlval->value.str.val = yytext; /* no copying - intentional */
zendlval->value.str.len = yyleng;
zendlval->type = IS_STRING;
yyless(yyleng-2);
BEGIN(ST_IN_SCRIPTING);
return T_COMMENT;
} else {
yymore();
}
}
and
<ST_IN_SCRIPTING>("?>"|"@>"|"</script"{WHITESPACE}*">"){NEWLINE}? {
zendlval->value.str.val = yytext; /* no copying - intentional */
zendlval->value.str.len = yyleng;
zendlval->type = IS_STRING;
BEGIN(INITIAL);
return T_CLOSE_TAG; /* implicit ';' at php-end tag */
}
As far as I can tell, it looks like it should. However when I try to
compile the code, I receive the following error:
"./zend_language_scanner.l", line 973: warning, rule cannot be matched
where line 973 is the line that my modification began, or the new opening
tag that I have added starts. I am not very well skilled in C, as yet, so
any help and/or comments on how I might be able to correct this slight
problem would be greatly appreciated.
As I mentioned before, at this time I am trying this out to satisfy my
curiosity. Please remember this when/if you respond to my inquiry.
Thank you ahead of time.
