Merge lp:~jeremy-munsch/synapse-project/fix-ssh-terminal into lp:synapse-project

[Jeremy Munsch]

Use
  x-terminal-emulator -e 'ssh %s' if x-terminal-emulator is available or default to GLib NEEDS_TERMINAL if a terminal is needed

to respect user default terminal instead of unefficient Glib default terminal
https://mail.gnome.org/archives/vala-list/2012-June/msg00061.html

It is only launching gnome-terminal or xterm, this is not the wanted behaviour.

The -e should work with any terminal emulator, this is i think a reliable and simple solution since synapse is targeting Debian based distros.
The fallback still supports other DE though.

[Jeremy Munsch (jeremy-munsch)]

I just saw in common actions that the problem is also to fix there.
I will also test if x-terminal-emulator is present and fall back to GLib solution if not.

I think of refactoring this into an Utils method.

[Jeremy Munsch (jeremy-munsch)]

I just did the just above.

If this is merged modifications would have to be done in PR https://code.launchpad.net/~jeremy-munsch/synapse-project/add-script-execute/+merge/277502 to make usage of the introduced "Utils.open_command_line"

[Rico Tzschichholz (ricotz)]

Was about to say that "x-terminal-emulator" might not be available/set.

[Jeremy Munsch (jeremy-munsch)]

Oops i made a mistake correcting now
"if (null != Environment.find_program_in_path ("zeal"))"

[Jeremy Munsch (jeremy-munsch)]

I just saw that redhat based distros use /usr/sbin/alternatives
and that synapse is distributed in redhat (fedora it seems at least).
http://rpmfind.net/linux/rpm2html/search.php?query=synapse

Should i update testing /usr/sbin/alternatives so it could be packaged more easily ?

[Jeremy Munsch (jeremy-munsch)]

Just updated the branch and corrected the commit message.

[Jeremy Munsch (jeremy-munsch)]

I have updated this. It now uses gconf to get default terminal, then fallbacks on x-terminal and then fallback on native and not reliable at all vala way.

[Jeremy Munsch (jeremy-munsch)]

So it is now using GLib.Settings

[Jeremy Munsch (jeremy-munsch)]

This should be ok now.

[Jeremy Munsch (jeremy-munsch)]

I have faith it should be ok.
