Re: [Qgis-developer] GGL2 - QGIS integration
Hi All We already got something with the previous implementation of GGL and the sextante Java version. I see on your repo a basic Python implementation to call GGL2 through Popen. Do you mean something like that? Are there any plans to make a C++ or Python port of GGL? From looking at the website it looks like the user will need java on their system to use it?

Are there any plans to make a C++ or Python port of GGL? From looking at the website it looks like the user will need java on their system to use it? AFAIU the plan are to keep it in Java, at now. The QGis integration idea are: 1 - a plugin to serve QGis as a GIS to GGL2 (read/load layers) 2 - (if they're will be foundings) run GGL2 commands from Sextante.

Re: [Qgis-developer] GGL2 - QGIS integration
In case of linux systems, I would think that most (if not all) installations include java, so it's not that much of a requirement. It might be more complicated in the case of windows and mac. It would be interesting to have a separate qgis-framework package (or similar name) that includes sextante and its dependencies and modules like GGL.

This probably makes more sense in linux (.deb/rpm/whatever) and osgeo4w though. But it would come at a cost for the maintainters.

Re: [Qgis-developer] GGL2 - QGIS integration
Hi Paolo. About the UI, we want to have a console so that the user can type the script and hit a play button. Similar to the Consola GGL panel towards the end of this video[1]. That's the previous version of the language, which was based in SQL. Appart of the UI, a qgis plugin must be created that exchanges messages with the GGL compiler in order to show results and inform the compiler about the layers loaded in qgis, etc. This approach already works in gvSIG. You can see how does it looks like from the user point of view here[2] and the technical details here[3]. I hope I've answered your question. Regards.

Re: [Qgis-developer] GGL2 - QGIS integration
Regarding your question, that is the idea. But actually the Qgis plugin will be the server since all the communication is started by the GGL2 environment. This plugin can be seen as a layer server that provides and stores (draws) layers: it opens a socket and manages the requests. Hi Victor, I've just given a rapid look to the GGL2 site and docs. If I understand it correctly, GGL2 will run in its own process, and the Qgis plugin will be the intermediary to expose QGis to GGL2 (through socket communication) as a GIS provider. The GGL2 commands will run on GGL2 which will be able to reference the layers (and the drawing) on QGis through the plugin. Right? giovanni Regards, Víctor. 2012/6/18 G.

Re: [Qgis-developer] GGL2 - QGIS integration
Hi, Yes, exactly. We plan to implement the same behavior as in gvSIG. You can see this in some videos. Referencing GIS layers: http://www.youtube.com/watch?v=tHJ3pFHHe6U Adding new layers: http://www.youtube.com/watch?v=qcTTUMGuL5Q We know that it could also be interesting to use GGL2 from within Qgis, integrating with Sextante.

What do you mean with SEXTABTE/QGis integration? Do you mean launching GGL2 commands from inside SEXTANTE (directed to the hosted GGL2 engine), or porting GGL2 to Python?

Re: [Qgis-developer] GGL2 - QGIS integration
Hi Fernando, I supposed you were somehow involved in those projects. Nice to meet you :) Now I will move my questions on GGL2 ml... giovanni 2012/6/18 Fernando González fergo...@gmail.com Hi Giovanni On Mon, Jun 18, 2012 at 4:01 PM, G. Allegri gioha...@gmail.com wrote: What do you mean with SEXTABTE/QGis integration? Do you mean launching GGL2 commands from inside SEXTANTE (directed to the hosted GGL2 engine), or porting GGL2 to Python? Yes, GGL2 scripts can be packaged and, as sextante is able to use third party processes, it should be possible to launch them from sextante. We already got something with the previous implementation of GGL and the sextante Java version. I see on your repo a basic Python implementation to call GGL2 through Popen. Do you mean something like that? That's the basic integration that will allow launching GGL2 scripts from QGIS. We plan to create a very simple interactive console at first, nothing to do with sextante. Sorry for so many questions, I ask them just to understand, because you're project is very interesting and I like to think about possible future applications. Please. :) I like very much domain languages. On this topic I also follow JEQL, from Martin Davis, and OrbisGIS [2] with its GDMS and GRAP tools. There is also jiffle[1] from Michael Bedward. I've copied some constructions from there. I've talked time ago with both of them (Michael and Martin) to try to collaborate... but it's not easy. Although the basic idea is the same, the approaches are very different. About OrbisGIS/Gearscape, some facts: - GDMS started in gvSIG (called GDBMS), in a boring summer, at home, at my home :) - We improved it *a lot* during the first 1.5 years of OrbisGIS development. - I forked it afterwards: Gearscape. - GGL stands for Gearscape Geoprocessing Language. - The GIS application (gearscape) and it's scripting language is no longer supported and we focus on the new language version (GGL2) and on the integration with other GIS applications (now is QGIS turn!).
