[Qgis-developer] morph delimited-text-provider to generic table-provider?

[Chris Crook]

Another thought .. why not use a plugin (which could emulate geometry component of DLT provider) to add geometry virtual fields to an existing layer?
Sounds really straightforward and would be available immediately and on older versions of QGIS.

Cheers
Chris

Fixing that should be possible.

Extending the CSV provider would result in rewriting a lot of driver
code which is already present in OGR.

I'd rather use one of the two methods

 * Geometry generators
 * Virtual layer

To build this functionality on top of any existing provider.
