NAME

wml::std::tags - Standard Support Tags

SYNOPSIS

#use wml::std::tags # Pass 2: advanced if constructs <ifdef varname thenval elseval> # Pass 3: support tag <perl> ... </perl> <say> ... </say> # Pass 4: support tag <m4> ... </m4> # Pass 4: symbols <symbol name value> <symbol name undef> # Pass 5: diversions <dump NAME> <enter NAME> ... <leave> <divert NAME> ... </divert> # Pass 6: support tag <asubst ...> ... </asubst> # Client-Side JavaScript: support tag <javascript [version=..] [language=..] [type=..] [src=...] [defer] [nohead] [nolang]> ... </javascript> # Resynchronize line numbers for more accurate pass 3 warnings <sync-lines>

DESCRIPTION

This include file defines some standard support tags one needs all the time. All tags are self-explanatory and briefly mentioned in wml_intro(1), except the last two which are described below. "<javascript>": This tag was primarily a shorthand for "<script type="text/javascript" language="JavaScript">" but it has evolved. If the "<head>" tag is defined and is a complex macro, e.g. when calling "wml::std::page", then Javascript code is automatically passed to this macro and should be diverted to the HEAD section of HTML documents. This diversion preserve lang slices in multi-lingual documents. Those features may be disabled by the ``nohead'' and ``nolang'' attributes. "<sync-lines>": WML tries to print information on input file and line numbers when warnings or errors are reported in passes 2 and 3. Some special sentences containing file names and line numbers are inserted during pass 1. So pass 2 have an accurate knowledge of where warnings appear in input file. But it also filters it without preserving lines, so after pass 2 information is almost unusable. By putting "<sync-lines>" in input file, it forces pass 2 to resynchronize information on line numbers. So for debugging pass 3, it could be of some help to insert "<sync-lines>" before ePerl code.
