But for emacs and gnus, one must hire a consultant to achieve the same effect. At least one of the manuals should say how. And in fact, if $BROWSER is good enough for other programs, it should be the default for emacs/gnus too. >>>>> "KY" == Katsumi Yamaoka <yamaoka@jpl.org> writes: KY> On Tue, 27 Mar 2018 09:31:34 +0800, 積丹尼さん wrote: >> RET runs the command shr-browse-url, which is an interactive compiled >> Lisp function in ‘shr.el’.

Thanks. Though I'm not on GNU/Linux now, is it ok to close this bug Jidanni? You should have xdg-open if you are on GNU/Linux. Even if (browse-url-can-use-xdg-open) returns nil, you can do: (setq browse-url-browser-function #'browse-url-xdg-open) ^ permalink raw reply [flat|nested] 4+ messages in thread
