Detecting spelling error in "f" prefixed strings in python code

[amittendulkar]

In Python you can write strings with an f prefix. Aspell is currently not considering this prefix for spell check.

For e.g.,

print(f'Hello world')

is considered as a spelling error (f'Hello is considered as a single word).

The best way to handle this is likely a new filter for python code that will transform something like:

  print(f'Hello world')

to just

          Hello world
