Can Bowler rename the variable in the format string literals?

Hi. I have some code that uses format string literals and .format() like below:

def foo(bar, zar):
    print(f'bar is {bar}, not {zar}')
    print('bar is {bar}, not {zar}'.format(bar=bar, zar=zar))

I want to rename the variable name bar to bar_new so the rename.py script is ready:

from bowler import Query

Query('.').select_var('bar').rename('bar_new').idiff()

I hope Bowler recognize the placeholder in string literal, {bar}, but it wasn’t:

--- ./format_string.py
+++ ./format_string.py
@@ -1,3 +1,3 @@
-def foo(bar, zar):
+def foo(bar_new, zar):
   print(f'bar is {bar}, not {zar}')
-  print('bar is {bar}, not {zar}'.format(bar=bar, zar=zar))
+  print('bar is {bar}, not {zar}'.format(bar_new=bar_new, zar=zar))
Apply this hunk [y,N,q,a,d,?]? 

I want Bowler to rename

• f'bar is {bar}, not {zar}' → f'bar is {bar_new}, not {zar}'
• .format(bar=bar, zar=zar) → '.format(bar=bar_new, zar=zar)

and this is what exactly the Refactor → Rename function does in PyCharm.

Is there a way to refactor my code like this? Thank you for your great tool.

The first part – renaming the variable within an f-string – is not currently supported, but I would be glad to review a PR if you feel like adding it. @jreese is that second part a bug, renaming the kwarg in a call? The docs are unclear at https://pybowler.io/docs/api-selectors#select-var
