Hi, here are some proposed patches which introduce the xhtml device. The features of -Txhtml are as follows:
* -Txhtml is honoured in groff, which passes the appropriate
dialect options '-x x' to pre-grohtml and post-grohtml.
* the device register is set to `html' but the number register
xhtml is also defined to 1, so the default html support macros
can all be reused.
* it utilises esr's mathml switch to eqn providing that the equation
is not in a picture or any other image (otherwise the image
contains the image of the equation as per -Thtml). MathML is
now emitted! I've had to modify eqn in a very small way to
make it emit the mathml as a parameter to a xhtml support
macro. These modifications are enabled by the eqn option
-Tmathml:xhtml (this is automatically done by the front end
groff).
* introduced the -V option to post-grohtml which issues a xhtml
1.1 validate button at the bottom of the document. Tested
against large documents such as pic.ms, but it currently
produces illegal xhtml when the document is split into
sections. I'll look into this and hopefully fix the huge files
issue at the same time as the xhtml split up - this area
looks like a good candidate for a rewrite.
Nevertheless, ignoring the section split, I think it should
produce valid xhtml 1.1. Certainly it should be seen as a
statement of intent :-)
* cleaned up a number of tags in post-grohtml for both -Txhtml
and -Thtml.
* added internal support macros to www.tmac
* added new number register \n[.O] which retrieves the image
nesting level (used with escapes \O etc).
* updated the grohtml manual page to reflect dialect option and
validate option.
I'd value any feedback,
enjoy,
Gaius
