SWIG generator of PEP-484 type hint stub files

[mcepl]

I know this is probably wrong place to ask, so I am expecting to be redirected somewhere else, but it would be awfully nice to have a tool, which would be able to generate *.pyi files for the Python bindings generated by SWIG.

You'd have to open a SWIG feature request. (Or contribute one yourself.)

This is a special case though of something we are keeping track of here: python/mypy#1240 -- for example we've actually got a use case for a similar thing for Protocol Buffers (protobuf).

[mcepl]

I have asked for it on the SWIG list already (http://thread.gmane.org/gmane.comp.programming.swig/21112), but I just thought that you may be able to push from the other side as well ;).

[gvanrossum]

Presumably you wouldn't be happy running stubgen on the SWIG output (plus that currently doesn't add any types to the output).

[mcepl]

Not sure what you mean as SWIG output. Generated C code? binary module? stubgen from 0.4.1 doesn't seem to react to either of these
_m2crypto_wrap.c.txt (yes, that's M2Crypto)

[gvanrossum]

Oh, sorry. Doesn't it generate Python glue? If it's just generating C, it
looks like stubgen it supposed to handle those, IIUC by importing them and
then introspecting the module dict. I've not tried this myself though.

[mcepl]

It doesn't. It basically generates the C code (see attached) which compiles to Python-compatible binary module. Anyway, I will continue to pursue this on the Swig list.

Just for the record, there is swig/swig#735
