I just released version 2.0 of Diffy.
I wanted to make it dead simple to generate attractive diff output from within a ruby application.
Here’s how you use it:
$ sudo gem install diffy $ irb >> string1 = <<-TXT >" Hello how are you >" I'm fine >" That's great >" TXT => "Hello how are you\nI'm fine\nThat's great\n" >> string2 = <<-TXT >" Hello how are you? >" I'm fine >" That's swell >" TXT => "Hello how are you?\nI'm fine\nThat's swell\n" >> puts Diffy::Diff.new(string1, string2) -Hello how are you +Hello how are you? I'm fine -That's great +That's swell
It also will generate nice html for you:
>> Diffy::Diff.new(string1, string2).to_s(:html)
- We were all having a good time.
- Soon it was very late.
“Time flies like an arrow” said I.
- Then I left.
