Function generate_variable_name

src/code_actions/extract_variable.rs:255–279

Generate a variable name (without `$` prefix) from the selected expression text. Heuristics: - Method call: `$user->getName()` → `name` - Property access: `$user->email` → `email` - Static call: `Carbon::now()` → `now` - Function call: `array_filter($items, ...)` → `arrayFilter` - Fallback: `variable`

(expression: &str)

/// - Function call: `array_filter($items, ...)` → `arrayFilter`
/// - Fallback: `variable`
fn generate_variable_name(expression: &str) -> String {

    // Try method call: `...->name(...)` or `...?->name(...)`

        return name;

    // Try property access: `...->name` or `...?->name`
