[Qgis-developer] Respecting new SAGA GIS versions in processing

[Rainer Hurling]

Victor,

I must say, that I am not one of the devs of SAGA GIS. I am only the
person, who is porting towards FreeBSD. So it is likely, that I am not
aware of all information, which should be present atm.

As far as I know, there is nothing like
http://sourceforge.net/p/saga-gis/wiki/Compatibility%202.1.3/ for
version 2.2.0.


One interesting way to get the needed information is to diff the two
interface description files:

http://sourceforge.net/p/saga-gis/wiki/Changelog%202.1.4/attachment/saga_cmd_interface_v2_1_4.txt

http://sourceforge.net/p/saga-gis/wiki/Changelog%202.2.0/attachment/saga_cmd_interface_v2_2_0.txt

That should point to the places with differences and in many cases it
describes all you need. A bit tricky are the cases, where
functionalities have been moved in the menu tree.


A second way could be, to compile a Unix version of SAGA GIS for
yourself. Then you can enable building of 'development tools'. After
that, in the GUI there is a new entry "Development Tools" with one entry
"Extract Tool and Menu Information". Depending on the value of 'level',
this will create two tables with information about tools and menues in
different detail. If you create these tables in versions 2.1.4 and
2.2.0, they could be diffed also.


If this is not sufficient, asking on
saga-gis-developer at lists.sourceforge.net could help. My experiences with
this list are very good. They are helpful and responsible.

Greetings,
Rainer
