This just reminds me that xdg-utils (a very small package not depending
on anything else and just consisting of a few scripts) provides a
command xdg-open. It calls the users preferred browser and works
pretty well for reportbug-ng.
Maybe icedove could check for the availability of this command and use
it before it tries to open x-www-browser as last resort?
Are there setups where xdg-open will not work?
I think it's very safe to use, since it will always call
sensible-browser if everything else fails. Looking at the script it
looks like it does the following:
1. Check if we're running KDE, GNOME or XFCE and call the appropriate
url-handlers in this case (like kfmclient exec $1 for KDE). This
means we're calling the *users* default browser here.
2. If not, try open_generic() (see below), which:
2.1. tries run-mailcap (whatever that does) or
2.2. as last resort calls sensible-browser which is provided by
debianutils which is of priority required and should be available
on every system.
I'm not sure what the following bash snipped exactly does, but it should
call sensible-browser as a last resort in every case. So yes, I think it
is safe to use and much better than just calling sensible-browser
without trying to find the users preference:
open_generic()
{
if which run-mailcap /dev/null
(echo $1 | grep -q '^file://' ||
! echo $1 | egrep -q '^[a-zA-Z+\.\-]+:'); then
local file=$(echo $1 | sed 's%^file://%%')
run-mailcap --action=view $file
else
sensible-browser $1
fi
if [ $? -eq 0 ]; then
exit_success
else
exit_failure_operation_failed
fi
}
I'm using it in reportbug-ng for a while now and haven't heard of any
problems so far. And since it is from freedesktop.org, I'm somewhat
confident, that this is the right way to call a browser across
different desktop-environments.
Thanks for considering xdg-open, even if you decide not to use it.
Cheers,
Bastian.
