how to obtain green background for some text?

how to obtain green background for some text?

[Gernot Hassenpflug]

Hello,

I have used boxquote.el a lot for marking cited text, but am searching
for a manner in which to mark text, particularly code, in my posting
with a green background. Searches for "background color",
"highlighting", and similar did not lead to any useful links for me
either for this newsgroup or the comp.text.tex group. I am hoping
someone here knows how to do this in gnus. I have also tried emacs's
text properties from the edit menu, but none of the font
foreground/background options are available in editing articles for
newsgroups.

Any help or hints appreciated.

I don't quite understand. You can't tell in a usenet-message how
another client should render your code (unless you use html, but that
is evil). Do you mean something like the #v+ and #v- marks? If I
recall correctly, No Gnus supports them, like
#v+
code...
#v-
But not many clients support this (afaik slrn does).

Where can I find out more about this?

Thanks! As the example given by Tom Rauchenwald appears to have used
this arcane (to me) #v+ ... #v-, I will investigate that.

I cannot give an example, as I cannot duplicate this. However, can I
give a reference to an article in another newsgroup that shows this?
The purpose is simple to make it easier to distinguish a minimal
example (LaTeX) which one can then copy verbatim (boxquote does not
lend itself to that as easily, obviously). In comp.text.tex there is
this article:

Path: news.motzarella.org!motzarella.org!news.swapon.de!fu-berlin.de!uni-berlin.de!not-for-mail

(body not copied)

This has some text which looks like the example line "code" given by
Tom Rauchenwald.

Thanks,

This entry in `mm-uu-type-alist' is responsible for this:

    (LaTeX
     "^\\([\\\\%][^\n]+\n\\)*\\\\documentclass.*[[{%]"
     "^\\\\end{document}"
     mm-uu-latex-extract
     nil
     mm-uu-latex-test)

I.e. if there's a line like \documentclass[foo]{bar} closed by a line
like \end{document} it is recognized as "non-MIME attachment":

,----[ <f1> v mm-uu-type-alist RET ]
| mm-uu-type-alist is a variable defined in `mm-uu'.
| Its value is shown below.
| 
| Documentation:
| A list of specifications for non-MIME attachments.
| Each element consist of the following entries: label,
| start-regexp, end-regexp, extract-function, test-function.
| 
| After modifying this list you must run M-x mm-uu-configure.
`----

It will not work in this group, because by default, it is only enable
in TeX groups:

,----[ <f1> v mm-uu-tex-groups-regexp RET ]
| mm-uu-tex-groups-regexp is a variable defined in `mm-uu'.
| Its value is "\\.tex\\>"
| 
| Documentation:
| *Regexp matching TeX groups.
| 
| You can customize this variable.
`----

Keep in mind that probably only Gnus will highlight the LaTeX document
in this way.  Or is anyone aware of another newsreader with this
feature?

Bye, Reiner.

Very interesting, I've never noted the use of mm-something-something
before. Time to read...

OK, but the example by a previous poster (using #v+ ... #v-) did show
up the same way. I will check documentation.

Yes, #v+/#v- is not restricted to particular group names whereas
\documentclass detection only makes sense in LaTeX related groups.

There's some documentation in (info "(emacs-mime)Non-MIME").  Probably
some references to this node should be added in the Gnus manual.

True that.

I'll see what I can put together in the next couple of nights. I'm no
expert of course, but a start is better than nothing.

Yes, that more or less it. Seems something like that, since whatever
it is you did made me see the line with "code" in green text on a sort
of beige background. I have no idea what you call that: are those #v
things escape sequences? I don't even know what I should be searching
for... when I look at the "raw" article in gnus, or reply, there is
nothing different visible anymore.

I did not know that you canot tell another client these things. For
instance, we have *text* which some readers will interpret as bold
text, or underlined, or something. I haven't seen any documentation in
gnus on that, but assumed it was standard rendering for newsreaders
that can do that (like showing smileys in graphics if they have the
capability).

I see, I am indeed using No Gnus v0.6.
