Certain cd commands fail when syntax validation is on

[dnivra]

Commands such as following fail when input validation is on.

In [1]: cd ..
Syntax Error

In [1]: cd -
Syntax Error

They work fine if input validation is turned off. Absolute paths work regardless. Is it possible to disable input validation for cd in total? I think that might be the better solution since there might be other variants of cd that might fail when input validation is on.

Thanks for reporting!

The validation is implemented here: https://github.com/jonathanslenders/ptpython/blob/master/ptpython/ipython.py#L85
Not sure what the best way to fix is.

Would disabling the validation for IPython magic commands help?
