When writing a NCL script, some high level graphics and contributed scripts often need to be loaded first. So, the head of a script looks like this:
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl" load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl" load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl" load "THE_PATH_OF_MY_SCRIPT.ncl"
With "NCL-import", you can write cleaner code:
import("gsn_code") import((/"gsn_csm", "contributed"/)) import("MY_SCRIPT")
The license for NCL-import is GPLv3.
- Set NCL_DEF_SCRIPTS_DIR environment variable
- Put ncl_import.ncl in NCL_DEF_SCRIPTS_DIR
NCL scripts in scripts/ directory are functions I use to make writing NCL code easier and faster. To use one of these scripts, just import it. Well, I will write documentation for these scripts later.
- Scripts with dependencies should be imported one by one in order, e.g., "gsn_csm" depends on "gsn_code".
- NCL (6.0 and 6.1) for Mac might have arbitrary errors or quit unexpectedly sometimes with custom scripts
