I did some changes and recompiled the code but the same error still
After doing some reading and research I came to know the processing toolbox
do not support optional parameters (please correct me if I am wrong).

Then i thought of deleting this line from the code:link
and recompiled it, but different from expected I still get the
argument (coloumn
name ) drop-down box in v.reclass function. Attached is the screenshot of
the option whose corresponding line is deleted.

Can you help me with that. :)

I saw the list of the projects and found them really interesting.

The first 3 are based on processing toolbox on which I am currently working
on and I am enjoying working on them and the last one is on importing OSM
data which was my last year’s GSOC project so it will be easy for me to
start working on it.

Please tell me your opinion on my interests and help me with choosing the

And also could you provide me with some reading material so that I could
proceed in the same direction.

Looking forward to your reply.
