[Fwd: Re: Do y'all have a suggestion for Ed?]

[Rick Grubin]

Regarding g2clib, I've been working with it and found its API  
reasonably easy to use for decoding, at least when compared to the  
ECMWF grib_api code.  The grib_api code, however, does have a nice  
built-in parser for reading codetables and extracting information at  
runtime.

Perhaps I'm missing something obvious (woudn't be the first time), but  
it seems that g2clib does not offer this capability (or does it, and I  
just don't see it?).  In looking at other GRIB2 decoders that make use  
of g2clib, it seems that those developers had to write their own  
methods for parsing/extracting info from codetables.  True?  If so, is  
there anything folks can share (preferably C code -- I know of Jeff  
Whitaker's python work and the Java decoder) that, given the info  
extracted from g2clib's data structure about a GRIB2 file, can decode  
text-based codetables?
