#? NAME
#? $0 - tag content generator for EMiR - Event Mappings in Reality
#?
#? SYNOPSIS
#? $0 [<options>] <TAG>
#?
#? OPTIONS
#? --h this text
#? --js only print JavaScript part from emir.html
#? --close generate content in </tag> instead of <tag>
#? --list-tags just list all tags defined in emir.html
#? --list-events just list all events defined in emir.html
#? --dbx-tty print debug information on console's (tty) STDERR
#? --dbx-html print debug information as HTML comment in generated data
#?
#? DESCRIPTION
#? Generates a complete HTML content and prints on STDOUT. The generated
#? content contains all known event attributes for the specified <TAG>.
#? The generated content (when saved to a file) is destined to be used as
#? link (to the saved file) in emir.html for the corresponding <TAG>.
#?
#? NOTE that only one TAG is expected as argument. If more than one TAG
#? is specified, content for each will be generated.
#?
#? Beside some constant text (content) the generated HTML looks like:
#?
#? <head> ...
#? <TAG id="TAG"\
#? EVENT0="return $e$(this,'EVENT0');"
#? EVENT1="return $e$(this,'EVENT1');"
#? EVENT...
#? >-test me-</TAG>
#? ...
#? </head>
#? <body>
#? <div><fieldset><span> <TAG> </span>
#? <label id="l-TAG-EVENT0">\
#? <input id="TAG-EVENT0" type="checkbox"> EVENT </label>
#? <label id="l-TAG-EVENT...
#? </fieldset></div>
#? ...
#? </body>
#?
#? or:
#?
#? <head> ... </head>
#? <body> ...
#? <div><fieldset><span> <TAG> </span>
#? <TAG id="TAG"\
#? EVENT0="return $e$(this,'EVENT0');"
#? EVENT1="return $e$(this,'EVENT1');"
#? EVENT...
#? >-test me-</TAG>
#? <label id="l-TAG-EVENT0">\
#? <input id="TAG-EVENT0" type="checkbox"> EVENT </label>
#? <label id="l-TAG-EVENT...
#? </fieldset></div>
#? ...
#? </body>
#?
#? LIMITATIONS
#? Following limitations exists (4/2020):
#? * parent|child no checks are done, if a tag is valid in the generated
#? HTML content (see DESCRIPTION of content above).
#? * multiple tags in the <head> section, a tag may occour more than
#? once, this is considered valid HTML content.
#? * <html> tag printed inside <body> tag (works for most Mozilla).
#? * <meta> tag printed in <head> section only.
#? * <script> tag printed in <body> section only.
#? * <script> tag does not contain a type= attribute.
#? * <style> tag does not contain a type= attribute.
#? * <body> tag not yet implemented. When given as argument for <TAG>
#? it will generate a <body> tag inside the <body> scope.
#? This behaviour is not yet tested (6/2020).
#? * <form> tag printed nested in <body> section, it's a bug here.
#? * <noframes> tag printed in <body> section, it's a bug here.
#? * <plaintext> tag not supported as most HTML render engines fail to
#? find its closing tag (3/2021).
#? * <invalid> tag any string can be used to generate the content, it
#? then will be treated as tag name and printed like any
#? valid tag name, consider this a feature ;-)
#? * --close NOT IMPLEMENTED for frame and framset tags
#? NOT IMPLEMENTED for empty (aka standalone) tags
#?
# Hacker's INFO
# The HTML tags and all known tag attributes are not defined herein but
# will be extraced from emir.html (which serves as master).
# Following markers are expected in emir.html:
# emir__INFO__
# emir__HEAD__
# emir__TITLE__
# emir__META__
# emir__EVENTS__
# emir__TAGS__
# emir__CHECK__
# emir__FIELDSET__
# emir__BODY__
# emir__JS__
# not yet used:
# emir__CSS__

# frame and frameset tags are a bit tricky, 'cause they are not inside
# <body> and do not allow other usual HTML tags, hence everything must
# be content of an (other) frame. The frames do not use their own file
# here, but all content as inline HTML in the src= attribute. Therfore
# following substitues in the inline HTML are necessary:
# ' must be replaced because they are needed where " are used
# " must be replaced by ' because HTML can't escape quotes
# < HTML entity must be replaced by another charcter
# > HTML entity must be replaced by another charcter
# HTML entities in src="data:text/html,..." are substituded before
# rendered, hence they cannot be used to escape their meta
# functionality
# The attribute src="data:text/html;charset=UTF-8, ..." must be used
# because unicode characters are used in the inline HTML.
# For these substitutes see $checkboxes below.
# The checks for the frame and frameset tag are similar, the generated
# HTML is very similar too, example:
#
# <-- example for frameset -->
# <frameset rows="50,50,*" id="frameset"
# -- list of event attributes -- >
# <frame id="check" src=" -- HTML with checkboxes --" />
# <frame id="dummy" src=" -- dummy HTML --" />

#
# <-- example for frame -->
# <frameset rows="50,50,*" id="frameset" >
