is this condensable?

if (expansion.length != 0)
    if (expansion.last().equals(' ')) return expansion.dropLast(1).toString()
return expansion.toString()

[Luke]

return if (expansion.isNotEmpty() && expansion.last() == ' ') expansion.dropLast(1).toString() else expansion.tostring()

[Robert]

If it would be allowed to strip multiple whitespaces on the end, then expension.trimEnd()

[Smallville7123]

ok

[Shawn A]

why are you calling toString?

[Luke]

+1 for .trimEnd(), I did not really consider the context

[Smallville7123]

return expansion.trimEnd().toString() works ^-^

@Shawn A cus expansion is of type StringBuilder

[ilya.gorbunov]

expansion.removeSuffix(" ")
