Dear John,

We currently don’t have any examples for using NEST directly from C++ because we (regrettably) do not have a fully defined C++ API for the NEST kernel. The reason for this is due to our historic focus on using NEST via the SLI intepreter and later from Python via SLI.

We are currently working on a new version of the NEST kernel which no longer will use the SLI interpreter (and thus no longer depend on SLI Datum data types). Our focus on in that project is on maintaining the NEST Python interface essentially unchanged, but in the process we are also slowly progressing towards a C++ API. If you want to explore this, you will find the code in the pynest-ng branch in my Github repo (https://github.com/heplesser/nest-simulator/tree/pynest-ng). The plan is that nestkernel/nest.h shall provide the API, but at present, we can neither promise completeness or stability of the interface nor provide any examples for running complete simulations entirely from C++ code. I hope we will have some by the summer.

If you would like to support our work by developing examples, please be in touch!

Hans Ekkehard

Dear NEST team,

I would like to intergrate nest in my c++ project however I couldn't find any examples on how to use nest in the C++ programing language.

Can you give me some simple examples like conecting 3 neurons?

Thanks in advance. _______________________________________________ NEST Users mailing list -- users@nest-simulator.org To unsubscribe send an email to users-leave@nest-simulator.org
