can't open link

can't open link

[jenenliu]

I can't open link when I am reading some posts in gnus, such as in
reddit.python
The error message is:
the link is considered to be unsafe; use the prefix arg to view anyway

How can I fix it, and how can I set the default browser to be w3m
I have w3m installed in Emacs
Thanks

Either you can do as it says, and use C-u before opening the link, or
you can change the variable mm-w3m-safe-url-regexp:

,----[ C-h v mm-w3m-safe-url-regexp RET ]
| mm-w3m-safe-url-regexp is a variable defined in `mm-decode.el'.
| Its value is nil
| Original value was "\\`cid:"
| 
| Documentation:
| Regexp matching URLs which are considered to be safe.
| Some HTML mails might contain a nasty trick used by spammers, using
| the <img> tag which is far more evil than the [Click Here!] button.
| It is most likely intended to check whether the ominous spam mail has
| reached your eyes or not, in which case the spammer knows for sure
| that your email address is valid.  It is done by embedding an
| identifier string into a URL that you might automatically retrieve
| when displaying the image.  The default value is "\\`cid:" which only
| matches parts embedded to the Multipart/Related type MIME contents and
| Gnus will never connect to the spammer's site arbitrarily.  You may
| set this variable to nil if you consider all urls to be safe.

Maybe by setting browse-url-browser-function:

,----[ C-h v browse-url-browser-function RET ]
| browse-url-browser-function is a variable defined in `browse-url.el'.
| Its value is browse-url-firefox
| Original value was 
| browse-url-default-browser
| 
|   This variable may be risky if used as a file-local variable.
| 
| Documentation:
| Function to display the current buffer in a WWW browser.
| This is used by the `browse-url-at-point', `browse-url-at-mouse', and
| `browse-url-of-file' commands.
| 
| If the value is not a function it should be a list of pairs
| (REGEXP . FUNCTION).  In this case the function called will be the one
| associated with the first REGEXP which matches the current URL.  The
| function is passed the URL and any other args of `browse-url'.  The last
| regexp should probably be "." to specify a default browser.
`----

  Best regards,

I run 'locate mm-decode.el', but I just can find a mm-decode.elc file.
Can I set the mm-w3m-safe-url-regxp variable in my .emacs file, and if
can, how
Thanks

In the usual way:

  (setq mm-w3m-safe-url-regexp nil)
