GDL - GNU Data Language, a free IDL (Interactive Data Language, see http://ittvis.com/idl/) compatible incremental compiler.
Hello all, finally I got something I was looking for a long time. Yesterday dowloaded GDL on my Ubuntu 12 by typing: >>sudo apt-get install gdl Installed flawlessly, but the first test building a wind rose (I am a meteorologist) was not quite a success. It says: >>>PLOT: Keyword parameter POLAR not allowed in call to: PLOT any workarounds about that issue? Am I, too demanding for a free version of IDL. Just wondering, if any other plotting rutines which have /polar keyword may help?
For interactive image processing at least the functionality of CURSOR, /NOWAIT of !MOUSE and of DEVICE, SET_GRAPHICS_FUNCTION=6 must be implemented correctly. Up to now this is not the case. The biggest handicap is the insufficient implementation of CURSOR. Although the crosshair is perfectly tracked in the graphics window, results are only returned when a mouse button is pressed. When I run PV_WAVE or IDL on the same machines (Linux: Kubuntu) everything works as expected. There are many shortcomings that require debugging and workarounds (e.g. you write an integer (2 bytes) to a file, and have to retrieve 4 bytes manually if you read it back), but the dynamic unnamed STRUCTURE works perfectly. So there is some hope that GDL may become a professional tool some time.
