I think there’s another option (in addition to improving SyntaxError, not instead of it): Add a defancier module to the stdlib. It has functions that take some text and turn smart quotes into plain ASCII quotes, dashes and minuses into ASCII hyphens, etc., or just detect them and produce useful objects and/or text. And it’s a runnable module that can either lint or fix source code. Then instead of telling people who get this SyntaxError “Use a proper editor, and all the code you wrote so far has to be rewritten or fixed manually, and that’ll show you”, we can tell them “Use a proper editor in the future, but meanwhile you can fix your existing script with `python -m defancier -f script.py`“. And a simple IDE or editor mode that doesn’t want to come up with something better could run defancier on SyntaxError or on open or whenever and show the output in a nice way and offer a single-click fix. There’s nothing in the stdlib quite like this, but textwrap, tabnanny, 2to3, etc. are vaguely similar precedents. And it seems like the kind of thing that will evolve on about the right scale for the stdlib—new problems to add to the list come up about once a decade, not every few months or anything. The place I’d _really_ like this is Pythonista, which does an admirable job fighting iOS text input for me, but it’s not so helpful for fixing up pasted code. (And needless to say, I can’t just get a better editor/IDE; it’s by far the best option for the platform.) (By the way, the reason I used -f rather than —fix is that I can’t figure out how to get the iPhone Mail.app to not replace double hyphens with an em-dash, or even how to fix it when it does. All of the other fancifier stuff can be worked around pretty easily, but apparently not that one…) _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/T6JPAQWP3P3IJSGGZWMDPBKPFUE6LQJ2/ Code of Conduct: http://python.org/psf/codeofconduct/
