}

Options

scopeDiff - Reports an error if upper and lower variable assign scope level difference is equal/bigger than scopeDiff. Default: 1.

Ignore errors

You can "bless" certain assignments as intentional via a special coffeelint-variable-scope-ignore annotation in code. Below code will not produce any coffeelint errors:

a = 1
###coffeelint-variable-scope-ignore###
a = 2

Notes:

• It needs to be a block comment
• It will ignore the next assignment (not line) in the code block
