I think that must be a Windows-only constraint. I can memmap with any offset and any length. > > What I learnt is that this is totally the wrong approach, and it needs > to be rewritten.

A more conventional record interface implemented in Python, which uses ndarray subclassing to provide enumeration, badstring, off-by-one, and split record handling. It needs to address two distinct needs : arr.fieldname needs to behave like `recarray`, but it should determine the subclass of the returned array from the dtype metadata associated with the field. To that end I started working on improving the datatype definitions (we can store such additional info in the 'metadata' field of the dtype object.). The format is compilable (ie. you can produce actual dtypes with metadata attached from it, and vice versa), but incomplete (off-by-one isn't handled. not sure if badstring is handled). I thought I'd pushed this work, but no.. Well, that's remedied now. > I think nohrio itself should > know what's in a data field, rather than just the dtype.

Right now, I'm both sick and caught up in moving. _______________________________________________ Ohrrpgce mailing list ohrrpgce@lists.motherhamster.org http://lists.motherhamster.org/listinfo.cgi/ohrrpgce-motherhamster.org
