This implementation diverges from Refurb's original implementation by
retaining the order of equal values. For example, Refurb suggest that
the following expressions:
highest_score1 = score1 if score1 > score2 else score2
highest_score2 = score1 if score1 >= score2 else score2
should be to rewritten as:
highest_score1 = max(score1, score2)
highest_score2 = max(score1, score2)
whereas this implementation provides more correct alternatives:
highest_score1 = max(score2, score1)
highest_score2 = max(score1, score2)

Nice, thank you, this looks great! I may make some small tweaks to better conform to some of our idioms but shouldn't require any major changes.

Can you instead pass in the ast::ExprIfExp here? That's what we prefer for new rules. So e.g. on line 1284, you'd change to:
Expr::IfExp(if_exp @ ast::ExprIfExp {
test,
body,
orelse,
range: _,
}) => {
...
}And then here, you'd pass in if_exp instead of the destructured fields. That way, callers can't pass in the "wrong" values.

Summary
Implements FURB136 that checks for
ifexpressions that can be replaced withmin()ormax()calls. See issue #1348 for more information.This implementation diverges from Refurb's original implementation by retaining the order of equal values. For example, Refurb suggest that the following expressions:
should be to rewritten as:

Test Plan
Unit test checks all eight possibilities.
