GDL Description

GDL (GNU Data Language) is a free IDL (Interactive Data Language) compatible incremental compiler GDL (GNU Data Language) is a free IDL (Interactive Data Language) compatible incremental compiler (ie. runs IDL programs). Here are some key features of "GDL": · Full syntax compatibility with IDL 6.0 ALL IDL language elements are supported, including: · Objects, · Pointers, · Structs, · Arrays, · System variables, · Common blocks, · Assoc variables, · All operators, · All datatypes, · _EXTRA, _STRICT_EXTRA and _REF_EXTRA keywords... · The file input output system is fully implemented (Exception: For formatted I/O the C() sub-codes are not supported yet) · netCDF files are fully supported. · HDF files are partially supported. · Basic support for HDF5 files. · Overall more than 330 library routines are implemented. For a sorted list enter HELP,/LIB at the command prompt and look for library routines written in GDL in the src/pro subdirectory. · SAVE and RESTORE are supported through Craig Markwardt's CMSVLIB library. · Graphical output is partially implemented. The PLOT, PLOTS, XYOUTS, SURFACE, OPLOT, TVRD and TV commands (along with WINDOW, WDELETE, SET_PLOT, WSET, TVLCT) work (important keywords, some !P system variable tags and multi-plots are supported) for X windows, z-buffer and postscript output. · GDL has an interface to python (python routines can be called from GDL). · GDL can be build as a pyhton module (GDL subroutines can be called from python). · No GUI support (widgets) is implemented so far.
