NCL.nix

A nix derivation for the NCAR Command Language (NCL).

Caveats

• On Darwin systems (i.e. macOS), I haven’t had any success running any of the graphical NCAR Computer Graphics Metafile (NCGM) display tools (e.g. idt, ictrans, and ctrans -d X11). The NCAR Graphics libs seem to work ok though (based on linking against them in ROMS-plot.nix).
• On nixOS, I haven’t had any success running any of the interactive graphical NCGM display tools (e.g. idt and ictrans). My workaround at the moment is to either use ctrans -d X11, or to just dump the NCGM to an hdf file (e.g. ctrans -d hdf ./gmeta.ncgm > ./gmeta.hdf).
