Building software is so much easier because of the Internet. Beyond StackOverflow, there are a some great tools such as Regex101, JS Fiddle and Pipedream which make it easy to run experiments and refine statements.
That’s where the emulator comes in. Build your statement in the emulator, test it, and then copy/paste into the browser where you’re building your flow.
The emulator runs purely client side with nothing passed back to the server beyond request logs. It’s mostly complete (see below).
If you find it useful, tweet me to let me know. If I see enough traffic, I’ll move it to a dedicated domain.
- A complete XML implementation, particularly xpath
- Some edge case locale sensitive date formatting.
- Testing across a wide range of browsers (LMK via Twitter if you find a bug)
