How much NMODL specification is covered?

[pramodk]

Hello,

I am looking at existing tools for parsing NMODL and would like to know how much NMODL specification / grammar this tool cover.

If you have done tests (e.g. from ModelDB mod files collection), could you comment overall coverage?

Thank you!

@pramodk Sorry it took so long for me to reply -- I have been receiving so many messages from github that this one went under my radar.
We have a bunch of tests, the main one involving all K channels in the Ion Channel Genealogy project. All but a few of those are parsed correctly - those that are not have been documented - and usually do semantically ambiguous things (which are accepted by the reference implementation nrnivmodl, but seem inconsistent with the language specs) like using undeclared variables in procedures, use of RANGE variables w/out corresponding a PARAMETER/ASSIGNED/READ etc.
Finally, we do not have a full C parser under the hood - so VERBATIM blocks are treated as such (well, verbatim - no parsing or semantic analysis).
