Andtunes and RegexTester
In a sudden bout of motivation, I’ve finished up a couple of little applications. They’re both free software.
RegexTester makes it easy to test a series of regular expressions all at once. You give it a list of regular expressions and a list of test data (one per line) and it will check each line to see if one of the regular expressions matches it.
So, if you’re interested, go and download them!
