Visualize which regular expression will match a given test string (Cocoa).
Reggy is a small OS X cocoa/objective-c application to very quickly visualize what a given regular expression will match given a test string. It will also tell you if you have errors in your regular expression.
What's new in Reggy
Added preference to apply sub-match/capture group coloring: each match or capture group gets a slightly different shade of color --- especially nice for nesting matches
Added preference to automatically use the clipboard contents on startup for the regular expression and/or the testing string
Added menu items to paste the clipboard directly into either the regular expression (Command+Shift+V) or the testing string (Command+Option+V)
Added a new and improved Reggy icon (Leopard Compatible/Resolution Independent)
Added help link for regular expression syntax preference (goes to wikipedia)
