tranformation MP_QSTR__slash_lib into /lib

Post by Roberthh » Sat Jan 26, 2019 7:18 am

Which setting/step in creating binaries causes during the translation of e.g. MP_QSTR__slash_lib into /lib the mapping of "_slash_" into "/"? I assume it is a singe setting/flag, but searching did not reveal the right place.

makeqstrdata.py processes the compiler-generated files and has

Code: Select all

codepoint2name[ord('/')] = 'slash'

I still have this problem, that a term MP_QSTR__slash_lib is NOT converted into "/lib", but into "_slash_lib". If I look into qstrdefs.generated.h, I find it there, opposed to other ports. Up to the point of the file qstrdefs.preprocessed.h it looks fine, but the last transformation does not happen for this specific file.

Is there a way to reproduce this? I.e. what port and/or custom build are you using?

That's the w600 port I am working on: https://github.com/robert-hh/micropytho ... ports/w60x
You can compile that with the standard setting: make V=s, but it requires a SDK for proper linking and compiling. A copy is here:
https://github.com/robert-hh/WM_SDK_W60X
But even without proper compiling, linking and loading it to a board, you can seen the wrong result int build/genhdr/qstrdefs.generated.h, because that's an early step.
The confusing thing is, that this seems to be the only failing QSTR, and that is for initializing sys.path
Obviously I can bypass the error by directly setting the path list with string constants. But it strange, and I must have had a similar problem in Jan 2019. I just don't remember what was the conclusion back then. It was definitely not with that port.

It looks like you need to add a line:

Code: Select all

Q(/lib)
to your qstrdefsport.h file.

Thanks. That did the trick.
