Strings and member-operators

okay, thanks dossy. so its also suppose to strip the whitspace even when
there are no double quotes. so i need to add #strip :

return str[0…0] + str[-1…-1] == ‘“”’ ? str[1…-2].strip : str.strip

if that dosn’t work, then i’m really missing the point! anyway, it was
just a fun little exercise.

thanks for the fun!

two simple bloopers a -1 was supposed to be a -2 and i wan’t returning
str on a non-match. does this pass now?

return str[0…0] + str[-1…-1] == ‘“”’ ? str[1…-2].strip : str

i was just trying to do it without regexp.

It still doesn’t make the tests pass:

Loaded suite tc_ts_strip_quotes

Failure occurred in test_strip_whitespace(StripQuotesTest)
[tc_ts_strip_quotes.rb:20]: didn't strip trailing whitespace. Expected

Here’s the failed test case, to save you some time:

def test_strip_whitespace
  assert_equal("foo", "foo ".stripQuotes,
    "didn't strip trailing whitespace")
  assert_equal("foo", " foo".stripQuotes,
    "didn't strip leading whitespace")
  assert_equal("foo", " foo ".stripQuotes,
    "didn't strip leading and trailing whitespace")
  assert_equal("foo", "\" foo \"".stripQuotes,
    "didn't strip leading and trailing whitespace inside double quotes")
  assert_equal("\"foo\"", " \"foo\" ".stripQuotes,
    "incorrectly stripped double quotes")
end

Specifically, it was this one:

  assert_equal("foo", "foo ".stripQuotes,
    "didn't strip trailing whitespace")

? It would be a surprise to me that a method like stripQuotes would
strip, well, something other than quotes.

Unless of course, that was documented somewhere. =) (Ever see the
list of constructors for Java BigInteger? That’s mindboggling.)
