<td colspan=2><tt>This class contains definitions on how to run programs and should<br>
be extended in ranger.defaults.apps<br>
<br>
The user can decide what program to run, and if he uses eg. 'vim', the<br>
function app_vim() will be called. However, usually the user<br>
simply wants to "start" the file without specific instructions.<br>
In such a case, app_default() is called, where you should examine<br>
the context and decide which program to use.<br>
<br>
All app functions have a name starting with app_ and return a string<br>
containing the whole command or a tuple containing a list of the<br>
arguments. They are supplied with one argument, which is the<br>
AppContext instance.<br>
<br>
You should define at least app_default, app_pager and app_editor since<br>
internal functions depend on those. Here are sample implementations:<br>
<br>
def app_default(self, context):<br>
if context.file.media:<br>
if context.file.video:<br>
# detach videos from the filemanager<br>
context.flags += 'd'<br>
return app_mplayer(context)<br>
else:<br>
return app_editor(context)<br>
<br>
def app_pager(self, context):<br>
return ('less', ) + tuple(context)<br>
<br>
def app_editor(self, context):<br>
return ('vim', ) + tuple(context)<br> </tt></td></tr>
