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.
