Input

→ View on rubyfmt.run

$g = 1
puts('"\#$g"')

@g = 2
puts('"\#@g"')

x = 3
puts('"\#{x}"')
puts(%q{text with \#{x} test})

Output

→ View on rubyfmt.run

$g = 1
puts("\"\\#$g\"")

@g = 2
puts("\"\\#@g\"")

x = 3
puts("\"\\#{x}\"")
puts("text with \\#{x} test")

Second Output

$g = 1
puts("\"\\#{$g}\"")

@g = 2
puts("\"\\#{@g}\"")

x = 3
puts("\"\\#{x}\"")
puts("text with \\#{x} test")

Expected behavior

The behavior should not be changed. The input contains strings without interpolation. The output has strings with interpolation. The output should also be stable.
