Oyster - Your Regex IDE
By RED When Excited Ltd
Open the Mac App Store to buy and download apps.
Regular expressions are a powerful tool for developers, but they aren't the easiest things to build and debug. Oyster helps you interactively build and test them, storing each "pearl" in an easy to access library.
With powerful syntax highlighting, dynamic updates of matches and the results of replacement patterns in test text it has never been easier to build and test your regular expressions.
Once you've got it just the way you like it, oyster lets you copy the code in one of 11 languages onto the clip-board or by dragging out the pip into your desired editor. Starting with Dash 1.8.5 (coming August 2013) you can even save your regular expression as a snippet in Dash's library.
You're not alone either, Oyster has built in integration with Oyster Farm, an online repository for pearls. You can download something that seems to fit the bill for you, and tweak it into what you would like. You can even share your changes, or entirely new pearls of your own.
• Keep a library of regular expressions, match tests, and replacement patterns (locally or in iCloud)
• Download and share pearls in the oyster farm
• Interactive highlighting of regular expression, matches, and pattern application
• Match highlighting includes group matches within overall match
• Handy Regex Reference sheet to help you tune your regular expression
What's New in Version 1.4
Greatly improved the feedback on matches and sub-groups. Oyster now highlights the whole match, and all sub-groups (and sub-sub-sub groups etc) much more clearly.
HTML doens’t work - no support
When pasting in HTML source code, it is parsed and then rendered as a webpage. I wanted to use this application to test a regex pattern to screen-scrape a website, but it looks like that isn’t possible. Tried to contact author’s support, but get taken to a dead website that just shows "Site Error: Unable to Load Site Preferences; No Preferences Found”.
