space_around_operators.md

Checks that operators have space around them, except for ** which should or shouldn't have surrounding space depending on configuration.

This cop has AllowForAlignment option. When true, allows most uses of extra spacing if the intent is to align with an operator on the previous or next line, not counting empty lines or comment lines.

Example:

# bad
total = 3*4
"apple"+"juice"
my_number = 38/4

# good
total = 3 * 4
"apple" + "juice"
my_number = 38 / 4

Example: AllowForAlignment: true (default)

# good
{
  1 =>  2,
  11 => 3
}

Example: AllowForAlignment: false

# bad
{
  1 =>  2,
  11 => 3
}

Example: EnforcedStyleForExponentOperator: no_space (default)

# bad
a ** b

# good
a**b

Example: EnforcedStyleForExponentOperator: space

# bad
a**b

# good
a ** b
