NAME

       htmlfix - Fixup HTML markup code

SYNOPSIS

       htmlfix [-o outputfile] [-F fixes] [-S fixes] [-v] [inputfile]

DESCRIPTION

       The htmlfix program reads inputfile or from "stdin" and performs the following actions (name of each fixup is within parentheses):

       (imgsize) : Adding WIDTH and HEIGHT attributes to IMG tags
	   For all "IMG" tags which don't already have both "WIDTH" and "HEIGHT" attributes (matched case insensitive), the size of the image
	   (taken from the "SRC" attribute) is determined and the missing ``"width=X"'' and/or ``"height=Y"'' is added to the list of attributes.
	   The intention is to speedup the layouting of the final webpage.

	   Don't intermix this with a size checker: htmlfix will only add missing width/height attributes and don't adjust ones with wrong
	   dimensions. This is because else the user wouln't be able to scale images (used a lot by webdesigners via 1pt dot-images).

	   There is a special case: When the "WIDTH" or "HEIGHT" attribute already exists and has a value of ``"*"'' this asterisk is replaced by
	   the physical value instead of appending a new attribute. Use when you want the attributes at a certain position, i.e. use this variant
	   as a placeholder.

	   HTMLfix supports one additionl feature in conjunction with "WIDTH" and "HEIGHT": "SCALE="factor and "SCALE="percent"%". This can be
	   used to scale the given or determined width and height values by multiplying with factor or multiplying with percent/100.

       (imgalt) : Adding ALT attribute to IMG tags
	   For all "IMG" tags which don't already have a "ALT" tag an "ALT=""" attribute is added. The intention is to both make HTML checkers
	   like weblint(1) happy and to demystify the final webpage for lynx(1) users.

       (summary) : Adding SUMMARY attribute to TABLE tags
	   This attribute helps non-visual rendering of tables by adding a hint on its contents, and it makes tidy(1) quiet.

       (center) : Changing proprietary CENTER tag to standard DIV tag
	   All proprietary (Netscape) "CENTER" tags are replaced by the HTML 3.2 conforming construct ``"<DIV ALIGN=CENTER>"''.

       (space) : Fix trailing spaces in tags
	   Appendix C of the XHTML Specification recommands putting a space before closing simple tags to help rendering by old browsers.  This
	   space is automatically added when this fixup is used.  On the other hand, all spaces before a right-angle bracker are suppressed.

       (quotes) : Adding missing quotes for attributes
	   All attributes of the form ``"...=xyz"'' are replaced by ``"...="xyz""''.  Furthermore all (color) attributes of the form
	   ``"...="XXYYZZ""'' (XX,YY,ZZ elements of set {0,..,9,a,..,f} are fixed to ``"...="#XXYYZZ""''.

       (indent) : Indenting paragraphs
	   Paragraphs enclosed in "<indent [num=N] [size=S]>"..."</indent>" containers are indented by N*S spaces.  When N=0 then the whitespace
	   block in front of the paragraph is removed.	Default is a 4 space indentation (N=1, S=4).

       (comment) : Out-commenting tags
	   Sometimes it is useful to temporarily out-comment a tag instead of completely removing it. This can be done by just adding a sharp
	   (``"#"'') character directly to the end of the tagname. The result is that the complete tag is commented out. For container-tags you
	   have to comment out the end-tag explicitly, too. Example: ``<"a# href="..."">''.

       (tagcase) : Markup-code case-conversion
	   Some people like their HTML markup code either to be all uppercase or all lowercase. This tag case-conversion is supported by the
	   internal "<tagconv case=...>"..."</tagconv>" container tag from HTMLfix. Use "case=upper" to translate the HTML tags in its body to
	   uppercase (default) or "case=lower" to translate them to lowercase.

OPTIONS

       -o outputfile
	   This redirects the output to outputfile. Usually the output will be send to "stdout" if no such option is specified or outputfile is
	   ""-"".

       -F fixes
	   This option specifies which specifix fixups are performed.  Its argument is a comma separated list of fixup names, and by default all
	   fixups are performed.

       -S fixes
	   This option does the inverse job, it skips specified fixups.

       -v  This sets verbose mode where some processing information will be given on the console.
