id: use-walrus-operator
language: python
severity: info
message: Use the walrus operator (`:=`) when an assignment immediately precedes an `if` that tests the same variable.
note: |
  Python 3.8+ supports assignment expressions via `:=`. When a variable
  is assigned and immediately tested in an `if`, the walrus operator
  combines both into one statement. Only apply where the style guide
  accepts assignment expressions. This rule handles the `if` rewrite;
  the companion rule `remove-walrus-source` deletes the redundant
  assignment.
rule:
  follows:
    pattern:
      context: $VAR = $$$EXPR
      selector: expression_statement
  pattern: "if $VAR: $$$B"
fix: |-
  if $VAR := $$$EXPR:
      $$$B
