raw-format string will be recognized as an error

[eternal-io]

Code snippet:

im.convert('1').save(rf'script\temp\{ord(c)}.png')
                                           ^ SyntaxError: invalid syntax *jedi*

rf - a convenient way of invoiding anomalous backslash in string, isn't it?

Moved to the parso issue tracker, but i agree that this is a bug.

Oddly enough this was only introduced in 0.8.1. In 0.8.0 this was still working.

Git bisect shows me d39aadc. I think it makes sense that this is the reason, because it changed some stuff regarding f-strings and backslashes in them.

git bisect start
git bisect good v0.8.0
git bisect bad master
git bisect run python3 -c "import jedi; assert jedi.Script('''im.convert('1').save(rf'script\temp\{ord(c)}.png')\n''').get_syntax_errors() == []"

This uses Jedi, I'm 99% sure it also works with Jedi. The git repo is parso.

Tagging @thatch, because he might now more (since he wrote dc9aadc). If you're interested in fixing the problem I'm happy to help.
