Disabling HTML rendering

Disabling HTML rendering

[Florian Weimer]

I distrust all HTML renderers, that's why I want to disable it and
show HTML in plain test.  Is there a way to do this, without ripping
out parts of the code?

If there is general interest in such a feature, I'm going to add a
global toggle which disables all external inline rendering (which
takes place without user interaction and can result in all kinds of
evil things because these tools are typically written in C).

Anything wrong with FAQ 4.6?

After our discussion on "Disable mailcap support"[1] in 2003 I have
added `mm-enable-external'.  Please elaborate if that's not
sufficient.

,----[ (info "(emacs-mime)Display Customization") ]
| `mm-enable-external'
|      Indicate whether external MIME handlers should be used.
| 
|      If `t', all defined external MIME handlers are used.  If `nil',
|      files are saved to disk (`mailcap-save-binary-file').  If it is
|      the symbol `ask', you are prompted before the external MIME
|      handler is invoked.
| 
|      When you launch an attachment through mailcap (*note mailcap::) an
|      attempt is made to use a safe viewer with the safest options--this
|      isn't the case if you save it to disk and launch it in a different
|      way (command line or double-clicking).  Anyhow, if you want to be
|      sure not to launch any external programs, set this variable to
|      `nil' or `ask'.

Bye, Reiner.
