note: this is the quick first draft, please feel free to refactor and add, but when adding, consider linking to other pages first, or creating a new page on this wiki
Goals
This project is intended for information about how different programming languages are used in OSG software and what's available.
A specific interest for this project is to discuss how to enhance or achieve interoperability between libraries and tools written in different languages.
I'm not sure if there should be an official committee for this (probably not), but I think this kind of project is needed as it serves for example the educational project and developers.
Audience
The contents are inteded for beginning developers who are looking for basic information and pointers, and for more seasoned developers who may not be well informed what's happening among languages they are not using.
Interoperability
- Maintain functionally equivalent libraries in two languages (JTS/GEOS)
- Use Swig (GDAL, GEOS)
- Use .Net/mono (MapWindow)
Using Swig
- How to achieve a robust mapping between memory management in low level language
and in the interface language?
C, C++, Fortran and other "low-level" languages
- Many fundamental libraries are written in these languages
- These can be wrapped efficiently with Swig
Java
Java is a hybrid in the sense that it's used for fundamental libraries but it is also often preferred also for its high-level features (strong OO). Notable Java OSG include JTS, uDig, ...
Scripting languages
Scripting languages take the burden of memory management and compilation and linking off from the developer.
Perl
- Geo modules in CPAN: http://cpan.org/modules/by-module/Geo/
- Cartography modules in CPAN (there's only one): http://cpan.org/modules/by-module/Cartography/
- Geography modules in CPAN: http://cpan.org/modules/by-module/Geography
- Tree::R module in CPAN: http://cpan.org/modules/by-module/Tree/
- GDAL/OGR has Swig-based Perl interfaces
- Discussion about gdal, ogr, some Geo, and Gtk2::Ex::Geo modules: http://map.hut.fi/PerlForGeoinformatics/
- Geo-Perl email list: https://list.hut.fi/mailman/listinfo/geo-perl
- FreeGIS database on Perl: http://freegis.org/database/?cat=24
Python
- Python Cartographic Library: http://zcologia.org/cartography
R
R is a language for spatial computing.
- R spatial: http://r-spatial.sourceforge.net/
Ruby
- FreeGIS database on Ruby: http://freegis.org/database/?cat=63
