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.

I have used g2clib for GRIB2 files and it is really good. It has
routines to
write all 8 sections of a GRIB2 file, and also it has routines to
decode a
GRIB2 file. The code is well documented too.
The library can be found at
http://oceanlab.rsmas.miami.edu/explorer/SEACOOS/v2/src/degrib/src/grib2lib/g2clib-1.0.2/
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?
Rick: g2clib does a nice job of decoding and encoding, but you are
right - it doesn't provide any way of matching the numeric code with the
associated text attributes from the WMO manual.
