class SyntaxTree::MAssign

MAssign is a parent node of any kind of multiple assignment. This includes splitting out variables on the left like:

first, second, third = value

as well as splitting out variables on the right, as in:

value = first, second, third

Both sides support splats, as well as variables following them. There’s also destructuring behavior that you can achieve with the following:

first, = value

Attributes

comments[R]

Array[ Comment | EmbDoc ]: the comments attached to this node

target[R]

MLHS | MLHSParen: the target of the multiple assignment

value[R]

Node: the value being assigned
