How to get web browsing functionality in emacs 23?

How to get web browsing functionality in emacs 23?

[guivho]

Hi,

I am running GNU Emacs 23.2.92.1 (x86_64-apple-darwin, NS
apple-appkit-1038.35) of 2011-01-15 on OSX 10.6
obtained from http://emacsformacosx.com/

I would like to browse certain web pages from within emacs and did not
find working browser functionality within the downloaded package.

When trying good old but slow M-x w3 emacs barks
 'font-default-size-for-device: Wrong type argument: arrayp, nil'

So I thought about trying emacs-w3m. I installed w3m and it works fine
from within a terminal.

When installing emacs-w3m, it complains about missing apel and flim
and missing load-file subst-ksc

I can hardly believe that I have to go through all that trouble to get
a working browser within emacs. Before I loose more time with this,
I'd like to hear some advise from the list.

Surely, I can't be the only emacs guy that wants e.g. to read www
based documentation from within emacs...

So any help would be most welcome,

TIA, Guivho.

Have you considered installing them then? It might be useful to install a 
package's dependencies.

Coincidentally I installed w3m just yesterday for the first time. It 
works fine so obviously it's not that much of a problem.

Well, apel-10.8, flim-1.14.9 as well as emacs-w3m-1.4.4 commplain
about not being able to open load file subst-ksc, and I don't know how
or where to get it.  In fact I got one at
http://repo.or.cz/w/emacs.git/blob_plain/e4904e23a5d19ea4c13fead4c0f0b61e14407077:/lisp/international/subst-ksc.el
and it byte compiled all right, but when I manually load it, it barks:
(void-function utf-translate-cjk-substitutable-p) apparently I'm
missing more than subst-ksc, and probably fetched subst-ksc from the
wrong location anyhow.

So I am back at square #1, unless you got some good advise about how
to proceed.

TIA, Guivho

Looks like an issue with cjk translation to unicode. Do you use those (eg. 
Korean)? I don't seem to have this file in my system. You might lack some 
other files, on which subst-ksc depends.

Get subst-ksc.el (and some subst-*.el) from GNU Emacsen 22.1-22.3!

Be sure you use cvs version (last) of emacs-w3m with all emacs >23

Hi Thierry,

> Be sure you use cvs version (last) of emacs-w3m with all emacs >23

Ok, I got the latest cvs tarball from
http://cvs.namazu.org/emacs-w3m.tar.gz and untarred it. It does not
have a configure script, so I executed autoconf (as instructed in the
README) and ran configure again to end up with a cryptic error
message:

$ cd elisp/emacs-w3m/
$ ./configure
./configure: command not found
$ autoconf
$ ./configure
checking whether make sets $(MAKE)... yes
checking for a BSD-compatible install... /usr/bin/install -c
checking for makeinfo... makeinfo
checking for texi2dvi... texi2dvi
checking for ptex... false
checking for jbibtex... false
checking for dvipdfmx... false
checking for texi2pdf... texi2pdf
checking for egrep... egrep
checking for emacs... /usr/bin/emacs
checking what a flavor does /usr/bin/emacs have... cat:
./conftest-27598: No such file or directory

configure: error:  is not supported.
$

So I'm afraid I'd need some more assistance and advice! I do hope to
end up with a working emacs-w3m!

TIA, Guivho.

It seem the configure script can't parse your emacs-version for some reason.
Maybe try: 

./configure --with-emacs=emacs

But you should ask now on emacs-w3m mailing-list how to build on mac.

Hi All,

The problem was caused by an old emacs 22 that was still hanging
around as /usr/bin/emacs and was picked up by the configure script
being executed in eshell in my current emacs 23. Removing the stale
emacsen and replacing them with symlinks to the current version,
solved my problems.

Thank you all for your time and advice,

Guivho.

Note that you should be very careful about running scripts inside
eshell. While eshell is a great interactive shell, it is not a fully
compliant shell. For example, it does not handle IO redirection. Many
scripts use such techniques and will not run correctly. To make it
worse, it will fail silently. Either use M-x
shell, M-x term or run outside of emacs.

As the Romans said, 'Experto Crede Roberto', you are very right. An
example of a task that fails from within eshell is MacPort activity ran
as 'sudo port'.

And I must admit that sometimes I am bitten by this before remembering
that there are those cases where our beloved eshell just doen't cut it
and shell is needed.

Thanks for reminding me,
