Question

I’m working to create a ruby regex that meets the following conditions:

Supported:

• A-Z, a-z, 0-9, dashes in the middle but never starting or ending in a dash.
• At least 5, no more than 500 characters

So far I have:

[0-9a-z]{5,500}

Any suggestions on how to update to meet the criteria above?

Thanks

This should work:

[0-9A-Za-z][0-9A-Za-z-]{3,498}[0-9A-Za-z]
