Introduction

Hi All,

I've just joined the list. 
I use to use w3 a lot back in the late 90s, but then stopped using it due
to a number of issues. I'd like to get back to using it now and as there is
a chance I may have some spare coding cycles coming up, thought I might try
to contribute by fixing some of the problems I've encountered. 

By way of providing some background.....

I've been using emacs for just over 10 years. My background is as an
analyst/programmer, but with not much lisp/elisp experience (just enough to
be dangerous). I'm also blind and make extensive use of emacspeak (one of
the reasons I'd like to see w3 move forward as it has a lot of good support
and integration for emacspeak users). 

Over the last few days, I've been playing with w3 again. I've run into one
problem I need to resolve. It appears that w3 is not handling font colors
correctly. While I'm legally categorised as blind, I do have a very small
amount of light perception. If I use a high contrast display with a black
background and light font, while I cannot read the font, I can make a
little out. I cannot use white background as this causes something similar
to snow blindness and is actually painful to look at. 

Currently, I'm running into numerous pages wehre w3 is rendering the
content with black and near black fonts on a black background. This is the
first issue I need to resolve. While I can hear the text, when I sometimes
ask someone to describe what they see on the page, I run into trouble
because they can't see it at all. The easiest example I can think of to
show this is with using google. 

change w3-default-homepage

Ahoy,

The existing w3-default-homepage is a 404 at cs.indiana.edu.
How about making it w3's page at www.gnu.org?

Emacs/W3 moves from CVS to Git

I just imported the CVS repository of Emacs/W3 into Git.  My aim with
this is to make it easier (for myself and others) to keep separate
branches, and to publish them and merge them.

To get a copy, run:

git clone git://git.sv.gnu.org/w3.git

Or if your firewall only allows HTTP, run:

git clone http://git.sv.gnu.org/r/w3.git

The CVS repository will be shut down at 2008-06-01, so you have three
months to get diffs for any local changes.

[bug #21601] Wrong handling of relative links with only query part

URL:
  <http://savannah.gnu.org/bugs/?21601>

                 Summary: Wrong handling of relative links with only query
part
                 Project: w3
            Submitted by: legoscia
            Submitted on: Saturday 11/17/2007 at 14:33

    _______________________________________________________

Details:

If the page http://foo/bar/baz.html contains a link ?foo, the link should
point to http://foo/bar/baz.html?foo, but W3 currently makes it
http://foo/bar?foo.

w3-kill-emacs-func

The function w3-kill-emacs-func does not heed the variable
url-history-track when calling url-history-save-history. It
should only do this if (eq url-history-track t), maybe taking
url-history-save-interval also into account.

Furthermore, this function has references to the variable
w3-temporary-directory which does not exist any more. By the way,
the function w3-show-dvi in w3-latex.el has a reference to this
variable as well.

"Page name is missing" when trying to edit wiki page

I try to edit e.g.

http://planetx.cc.vt.edu/AsteroidMeta/HomePage

by clicking on the "Edit this page" link

http://planetx.cc.vt.edu/AsteroidMeta/?action=edit;id=HomePage

but what comes up is the page

http://planetx.cc.vt.edu/AsteroidMeta/?action=edit

with the error

"Page name is missing"

And this same error comes up if I supply the correct URL by hand.

wrong font-size calculations in css.el and font.el

The function css-expand-length does not take the default character size
in pixels into account when calculating em and ex values. This results
typically in values very much too large.

I would like to suggest using something like the following in the
condition branch that deals with em and ex values:

    (round (font-spatial-to-canonical
            (concat (number-to-string
                     (* (string-to-number (match-string 1 spec))
                        (if height (frame-char-height) (frame-char-width))))
                    "px")))

I don't know if it is advisable to use font-spatial-to-canonical. But
it could be used in other places in this function too.

By the way, this function font-spatial-to-canonical has another bug:
Pixel values are calculated with

	(setq retval (* num (/ pix-width mm-width) (/ 25.4 72.0))))

instead of the correct

	(setq retval (* num (/ mm-width pix-width) (/ 72.0 25.4))))

i.e., exactly the other way round with respect to dividing and
multiplying.

w3-download-callback should consider :redirect

The new URL library passes additional arguments in case of a redirect
(:redirect ...). Not only w3-fetch-callback, but also
w3-download-callback should take these into account.

w3 manual does not permit modification?

The texinfo manual for w3 has the following license notice:

    Permission is granted to make and distribute verbatim copies of
    this manual provided the copyright notice and this permission notice
    are preserved on all copies.

    Permission is granted to process this file through Tex and print the
    results, provided the printed document carries copying permission
    notice identical to this one except for the removal of this paragraph
    (this paragraph not being relevant to the printed manual).

    Permission is granted to make and distribute verbatim copies of@*
    this manual provided the copyright notice and this permission notice@*
    are preserved on all copies.

This doesn't give any permission to modify the manual.  Is this
intentional?  Could you clarify the license?

w3-parse.el modification

Hi, 

I use W3 in mh-e to display HTML emails, and since some time it broke
regularly on M$ originating emails, that contain tags in other
namespaces.

I modified w3-parse.el to ignore tags containing ":", a rather ugly hack
but my elisp is very limited.

Maybe you can use it, or implement a better handling of name-spaces,

Regards,

Arjen
