[ncl-talk] [vim for ncl] sharing a short script to create ncl.dic

[Packard Chan]

Hi all,

I am using vim editor for NCL, and I appreciated the tips in
https://www.ncl.ucar.edu/Applications/editor.shtml#vim. I also appreciated
that the ncl3.vim file is updated promptly after release of the new version
of NCL. However, I noticed that ncl.dic has not been updated for 4 years.

Another problem with the current ncl.dic is that some keywords are not
showing up correctly with my version of vim (7.2). For example, if I type
in "xy", then Ctrl+n, the keyword "xyCoordData" is trimmed to "xyCo" and
several words from "xyCoordDataSpec" to "xyLineDashSegLenF" are missing. I
noticed that my version of vim imposed a 510-byte limit on the maximum line
length for the dictionary file (see :help 'dictionary' in vim). I believe
this explains the problem seen in
https://www.ncl.ucar.edu/Support/talk_archives/2011/1828.html.

Now, this is my solution:

#!/bin/sh
# produce ncl3.dic from downloaded ncl3.vim

#wget http://www.ncl.ucar.edu/Applications/Files/ncl.dic
#mv -i ncl.dic ~/.vim/dictionary/
#wget http://www.ncl.ucar.edu/Applications/Files/ncl3.vim  # updated 2 days
after release of 6.4.0
#mv -i ncl3.vim ~/.vim/syntax/

sed -n '/^syn keyword nclKeyword/p' ~/.vim/syntax/ncl3.vim > dic3b.ncl
sed -n '/^syn keyword nclBoolean/p' ~/.vim/syntax/ncl3.vim >> dic3b.ncl
sed -n '/nclKeyword/d;/nclBoolean/d;/^syn keyword/p' ~/.vim/syntax/ncl3.vim
>> dic3b.ncl
sed -i 's/syn keyword [^ ]* \+\b/\n/' dic3b.ncl

t_update=`sed -n '/^" Updated/s/" Updated //p' ~/.vim/syntax/ncl3.vim`
head -n 5 ~/.vim/dictionary/ncl.dic |sed "s/\(^.* Updated:
\+\b\).*$/\1$t_update/;s/\(^.* Author: \+\b\).*$/\1Packard Chan\n\" Based
on previous version by Prince K Xavier, and ncl3.vim by Carl Schreck/" >
~/.vim/dictionary/ncl3.dic
sed '1d' dic3b.ncl |fold -w 500 -s >> ~/.vim/dictionary/ncl3.dic
rm dic3b.ncl

This script puts the dictionary file in ~/.vim/dictionary/ncl3.dic. Make
sure you update your vimrc with this new dictionary file location.

Any comments and suggestions are welcomed.

Cheers,
Packard
