I tried installing https://nuwen.net/mingw.html but still no error, the command just hangs with no output.

Have you installed python driver on bblfsh server?
Is (bblfshd) running locally or inside a docker container?

Hey Kuba,

I have the bblfshd running in a docker container.

And these are my drivers. If I try to update the python one it says this is already the latest.

PS C:\Users\james> docker exec -it bblfshd bblfshctl driver list

ok, could you give me your python file, so I'll try to reproduce it?

Sure, although it happens with every file that I've tried and I managed to get everything working with ubuntu, so I think it is the windows setup.

ast.py

import bblfsh

client = bblfsh.BblfshClient("localhost:9432")
print("parsing")
ctx = client.parse("ast.py")
print("printing ctx")
print(ctx)

I was wondering is it possible to query on a line number? And is it possible to go from a node up to the parent node? Or can you only iterate like -

ast = ctx.root
it = ast.iterate(bblfsh.TreeOrder.POSITION_ORDER)
for node in it:
    print(node)

Ohh, ok - in my opinion it can't work well on windows (where bblfshd internally creates subcontainers with communicates over grpc on top of std. IO).

Regarding query -you can filter with xpath whatever you want, e.g. next(ctx.filter("boolean(//*[@startOffset or @endOffset])"))
Every position is a tuple (Type, Col, Line, Offset), so in theory it should be doable.
