About GDL: some pros and cons • inherited from IDL: • one can process data and get customized plots of them with a few (dozens) lines of code • opens many data formats: text, binary, netCDF, HDF, FITS, GRIB. . . • GDL specific: • it’s free! and you can modify and expand it to suit your needs • numerics based on reliable open-source libraries as (GSL, FFTW, . . . ) • enhanced CLI thanks to readline, SVG & GRIB support, Python bridge • compiles on many platforms (Linux, BSDs, OSX, Solaris, Cygwin, ...)

About <strong>GDL</strong>: some pros <strong>and</strong> cons<br />
• inherited from IDL:<br />
• one can process data <strong>and</strong> get customized plots of them<br />
with a few (dozens) lines of code<br />
• <strong>open</strong>s many data formats: text, binary, netCDF, HDF, FITS, GRIB. . .<br />
• <strong>GDL</strong> specific:<br />
• it’s <strong>free</strong>! <strong>and</strong> you can modify <strong>and</strong> exp<strong>and</strong> it to suit your needs<br />
• numerics based on reliable <strong>open</strong>-<strong>source</strong> libraries as (GSL, FFTW, . . . )<br />
• enhanced CLI thanks to readline, SVG & GRIB support, Python bridge<br />
• compiles on many platforms (Linux, BSDs, OSX, Solaris, Cygwin, ...)<br />
• inherited from IDL:<br />
• bit archaic syntax with constructs from numerous languages from<br />
Fortran to C++ <strong>and</strong> inconsistent naming of library routines . . .<br />
but who cares, it’s meant to be more a bash than a Java of scientific<br />
computing – it’s intended for short scripts <strong>and</strong> interactive usage<br />
