[pgrouting-users] How many people use the wrapper functions?

[Stephen Woodbridge]

Hi Pavel,

Thanks you for your feedback. This is exactly why we are thinking about 
thinning down the list of function. The history on this was that these 
were originally written to explain how to use the core functions 
efficiently but the problem is that there are only examples and they 
really don't fit well to most peoples use cases. I believe (maybe 
erroneously) that most users have taken one  or two of the wrappers and 
modified them for their own use cases.

One of the things that we will also be working on is a new tutorial 
based on the new algorithms and we hope to address some of these 
educational issues in that also.

Thanks again for your feedback.

I look forward to hearing from others on either side of these issues.

Thanks,
   -Steve
