# Refactoring Code
|
||
|
|
|
||
|
|
Sometimes you want to make big changes to your codebase like moving methods or classes.
|
||
|
|
|
||
|
|
Psalm has a refactoring tool you can access with either `vendor/bin/psalm-refactor` or `vendor/bin/psalm --refactor`, followed by appropriate commands.
|
||
|
|
|
||
|
|
## Moving classes between namespaces
|
||
|
|
|
||
|
|
`vendor/bin/psalm-refactor --move "Ns1\Foo" --into "Ns2"` tells Psalm to move class `Ns1\Foo` into the namespace `Ns2`, so any reference to `Ns1\Foo` becomes `Ns2\Foo`).
|
||
|
|
|
||
|
|
## Moving and renaming classes
|
||
|
|
|
||
|
|
`vendor/bin/psalm-refactor --rename "Ns1\Foo" --to "Ns2\Bar\Baz"` tells Psalm to move class `Ns1\Foo` into the namespace `Ns2\Bar` and rename it to `Baz`, so any reference to `Ns1\Foo` becomes `Ns2\Bar\Baz`).
|
||
|
|
|
||
|
|
## Moving methods between classes
|
||
|
|
|
||
|
|
`vendor/bin/psalm-refactor --move "Ns1\Foo::bar" --into "Ns2\Baz"` tells Psalm to move a method named `bar` inside `Ns1\Foo` into the class `Ns2\Baz`, so any reference to `Ns1\Foo::bar` becomes `Ns2\Baz::bar`). Psalm currently allows you to move static methods between aribitrary classes, and instance methods into child classes of that instance.

|
## Moving and renaming methods
|
||
|
|
|
||
|
|
`vendor/bin/psalm-refactor --rename "Ns1\Foo::bar" --to "Ns2\Baz::bat"` tells Psalm to move method `Ns1\Foo::bar` into the class `Ns2\Baz` and rename it to `bat`, so any reference to `Ns1\Foo::bar` becomes `Ns2\Baz::bat`).
