GDL - GNU Data Language, a free IDL (Interactive Data Language - see
(IDL 6.0 compatible incremental compiler capable of running programs
written in IDL)
Note: If you never heard of IDL or GDL you probably don't need to read
GDL can now be build as a python module, allowing IDL/GDL routines to
be called from python (for python standards the installation is quite
unusual but simple, see INSTALL and PYTHON.txt for details). This is in
early beta stage right now. Depending on the interest, the interface
might be extended in the future.
For passing arrays to and from python, GDL uses numarray.
Gaurav Khanna provides binaries for Mac OS X on his HPC page:
*FULL* syntax compatibility with IDL 6.0
*ALL* IDL language elements are supported, including:
_EXRA, _REF_EXTRA and _STRICT_EXTRA keywords,
Objects, Pointers, Structs,
Common blocks, Assoc variables,
