Folks,
I have a general need to be able to create, browse, and write
netCDF files in an extremely flexible way. In particular, I
want to be able to copy variables and attributes from one
file to another without thinking too much about it.
To this end, I have borrowed heavily (well, I stole most of
the good ideas, really) from Mark Hadfield's Motley Library
and its wonderful netCDF routines.
http://www.dfanning.com/hadfield/IDL/README.html
When I started this project, I thought Mark's routines could
use more documentation and error handling. When I finished,
I realized I hadn't added much value to what Mark had already
provided. But, of course, hindsight is 20-20. I have learned
a lot about netCDF files in the past month or so, and certainly
enough to know I am probably going to be surprised in the future
by how little I know.
In any case, the new programs I have written have provided
me with some new tools for working with netCDF files and I
thought they might be of interest to a wider audience.
http://www.dfanning.com/progrms/ncdf_tools.zip
Because most of these tools are written as objects, and because
that scares the bejesus out of many IDL users, I have provided
an example file, NCDF_File_Examples, that shows you exactly
how to create a netCDF file, copy some of the contents to
another netCDF file, and then read the netCDF file to do
something useful in IDL.
http://www.dfanning.com/programs/ncdf_file_examples.pro
I have been particularly careful to document these
routines so they can be used by a wider audience.
In addition to Mark, I have been greatly enlightened in my
netCDF studies by IDL newsgroup regulars Paul van Delst and
Ken Bowman. I am exceedingly grateful to them and to all of
you who pester me with questions and suggestions for
improvement. Even though I already have a wife, I appreciate
you, too. :-)
Cheers,
David

The is OT, but do you use different repositories for your different projects? I noticed
the unit testing project revision numbers are much lower than those for your idldoc
project? I presume that was done so you could use an externals defn for various projects
to see others (like you did in your unit test project for idldoc)?
Currently, we have your entire library explicitly checked into our repository. I will soon
move that to externals definitions of a tag+revision# - do you have a list (or a link to a
list) of your trac/svn project URLs on your blog? Or do they all use the same URL naming
convention?
cheers,
paulv

I definitely want to talk to you about this. Also, there are community
related aspects to this that I think would be good fodder for the round
table discussion on Tuesday. I assume you will be there on Tuesday also?

Yes, I have Trac and svn setup and ready to go!

With a subversion repository, you wouldn't be. Users would be responsible for upgrading
their own working copies.

It's not a perfect system, but I have to say that I found using subversion was one of
those rare experiences where you think "Why can't everything work this well?" It really is
a tool that will make you life easier. And, while the learning curve isn't flat, it's not
that steep. It's a good mix of functionality and ease-of-use for those of us who aren't
hard-core software engineering types.
Couple it with a SCM tool (e.g. http://www.edgewall.com/trac. I use it here and I believe
MikeG uses that for his idldoc stuff) and you'll be set! :o)
cheers,
paulv

I'm going to talk to Mike Galloy at this week's IDL
User's Group meeting. He has a nice Subversion solution
for me if I would just get off my duff and use it. It
involves learning something new, which I am REALLY
loath to do. :-)
Cheers,

P.S. Anyway, don't download them yet. I just finished my
presentation preparation and I have a slew of new programs
to upload, including a new one for the NCDF_Tools.zip file. ;-)

May be use mercurial. http://mercurial.selenic.com/
It is much easier to handle and you don't rely on only one server.

working with a distributed source control management tool is more fun ;)
