LaTeX-editing TEXTAREAs using w3m?

LaTeX-editing TEXTAREAs using w3m?

[Nicolas Neuss]

Hello,

I have a web server which renders small LaTeX snippets as PDF or HTML/GIF.
The LaTeX snippets can be edited via a browser as HTML-textarea fields.
However, using standard browsers I miss the LaTeX-editing features I have
available when editing LaTeX code with Emacs.

One possible remedy would be to use w3m and switch on LaTeX mode when
editing textareas.  I have tried this, and the straightforward way did not
work (that is, the w3m information did get lost when I did M-x latex-mode).
Does anyone know if such a feature is easily possible?

Thank you very much,

Nicolas

To be more precise "the Emacs interface to w3m" (or whatever other Emacs
browser might be available).

I guess you'll have to edit your LaTeX code in a temporary LaTeX-mode
buffer then paste it back to your browser text box.

Or try the indirect buffer feature. Something like this :

(defun edit-latex (start end)
   (interactive "r")
   (switch-to-buffer
    (make-indirect-buffer (current-buffer) "*edit-latex*" t))
   (narrow-to-region start end)
   (toggle-read-only -1)
   (latex-mode))

This is probably no help, but isn't there a way to open an editor (e.g. the
value of $EDITOR) from a Web browser for such a text area? If there is, then you
should be able to use emacsclient (or gnuclient) to do that editing with Emacs.

That's one of the things emacsclient is for: to let you open Emacs from some
other app. Dunno if Web browsers let you do that easily, though.

Firefox does.

Look into using : https://addons.mozilla.org/en-US/firefox/addon/4125

(setq w3m-form-textarea-edit-mode 'latex-mode)

In infinite wisdom Nicolas Neuss <lastname@math.uni-karlsruhe.de> spoke thus:

If you use Firefox, check out the mozex extension
<http://mozex.mozdev.org/development.html> It allows you to open
textarea in emacs.  Install and check out its preferences to set your
editor.

Wow!  I guess this is the easiest way, although the other suggestions are
interesting as well!

Thank you all for the very useful feedback,

Nicolas

Yes, thanks for the link; works fine. Makes Firefox pop up an Emacs window (via
emacsclient) whenever you use an HTML text area. Just use `C-x #' to send the
edited text back to the browser.

Linux users (X) might be interested in this little script which I call
from the extension above:

,----
| wmctrl -a emacs
| source ~/bin/emacs.bash
| edit $1
`----

wmctrl brings emacs to the foreground and the emacs.bash is a copy of
the bash script which defines edit() to use emacs client or start emacs
as appropriate. Edit as appropriate.

Caveat : When using with gmail for example set gmail up to use "basic
html" or it wont work.

But wmctrl is not installed as default, at least on this machine here?
