[Qgis-developer] Publishing Custom Python Expression Functions for QGIS

[Khare Simran]

Hi,

I am Simran, an intern at the Institute for Software in HSR Rapperswil. I have come up with some Custom Python Expression functions for QGIS. They are:


1. hstore_get_value(), hstore_exist(), hstore_contains_key_value() and hstore_contains_hstore() :

These functions can search for keys and values in hstore strings. They are useful for selecting features based on their tags, which are of hstore type.



2. maxofallvaluesplusone('fieldName')

Given a field name, this function returns 1 + the maximum of all values in that field. It is useful for automatically generating a unique id (for example fid) every time the user adds a new feature to a layer.


You can find the functions on Github: https://github.com/simran001/custom-expression-functions


Please let me know if I should publish these functions as part of the QGIS Resource Sharing Plugin, or if it would be a better idea to make a pull request at https://github.com/NathanW2/qgsexpressionsplus.


Thanks!


Best regards,

Simran
