Attached is the initial wtk->lw_geom parser.
There is also w lw_geom->wkt in there. which could perhaps be
considered, it's very small and clean.
The parser has no dependencies on anything, parse_WKT function takes and
allocator function and a error log function, likewise the unparser.
There is also a build script to make a test app that roundtrips through
the parser and unparser some test geometries..
It is much more compliant than the old parser, and allows case
insensitive geometries etc.
You should just need to include wtkparse.h and all should be good.
I am pretty happy with parsing / unparsing system, it should be very
fast and stable. It should also be easy to verify as the code is very
Perhaps we want to do a flex / bison wkb parser also?
