Badly formatted generated stub

[gramster]

Describe the bug

When using pyright to generate a type stub the output is getting mangled.

To Reproduce

1. Install pyright and matplotlib
2. Run pyright --createstub matplotlib.axis
3. Look at the resulting typings/matplotlib.axis file; there are issues with multi-line strings. I'm not sure if there are any other issues or if it is just this.

Expected behavior

Output should preserve the docstrings.

This was with pyright 1.1.248

The current logic truncates string literal expressions to 32 characters. This was done for the benefit of logging and error messages that include expressions. Truncating in the context of stub generate isn't appropriate, so I've updated the expression printing code to perform truncation conditionally based on a flag passed by the caller. This will be addressed in the next release.

This is addressed in pyright 1.1.249, which I just published. It will also be included in the next release of pylance.
