From ad619e02c465eebd15fa57dc658f8e042decdebb Mon Sep 17 00:00:00 2001 From: duerst Date: Mon, 28 Nov 2016 08:37:32 +0000 Subject: implement String/Symbol#casecmp? including Unicode case folding * string.c: Implement String#casecmp? and Symbol#casecmp? by using String#downcase :fold for Unicode case folding. This does not include options such as :turkic, because these currently cannot be combined with the :fold option. This implements feature #12786. * test/ruby/test_string.rb/test_symbol.rb: Tests for above. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@56912 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- test/ruby/test_string.rb | 7 +++++++ test/ruby/test_symbol.rb | 8 ++++++++ 2 files changed, 15 insertions(+) (limited to 'test') diff --git a/test/ruby/test_string.rb b/test/ruby/test_string.rb index b1d795e183..90f48e4f08 100644 --- a/test/ruby/test_string.rb +++ b/test/ruby/test_string.rb @@ -2210,6 +2210,13 @@ CODE assert_equal(1, "\u3042B".casecmp("\u3042a")) end + def test_casecmp? + assert_equal(true, 'FoO'.casecmp?('fOO')) + assert_equal(false, 'FoO'.casecmp?('BaR')) + assert_equal(false, 'baR'.casecmp?('FoO')) + assert_equal(true, 'äöü'.casecmp?('ÄÖÜ')) + end + def test_upcase2 assert_equal("\u3042AB", "\u3042aB".upcase) end diff --git a/test/ruby/test_symbol.rb b/test/ruby/test_symbol.rb index d8c91c1eea..24d319211f 100644 --- a/test/ruby/test_symbol.rb +++ b/test/ruby/test_symbol.rb @@ -276,6 +276,14 @@ class TestSymbol < Test::Unit::TestCase assert_nil(:foo.casecmp("foo")) end + def test_casecmp? + assert_equal(true, :FoO.casecmp?(:fOO)) + assert_equal(false, :FoO.casecmp?(:BaR)) + assert_equal(false, :baR.casecmp?(:FoO)) + assert_nil(:foo.casecmp?("foo")) + assert_equal(true, :äöü.casecmp?(:ÄÖÜ)) + end + def test_length assert_equal(3, :FoO.length) assert_equal(3, :FoO.size) -- cgit v1.2.3
