no timeout error or functionality #58

Closed gachteme closed 4 years ago

gachteme commented 4 years ago

Proposal to add a detailed timeout error allowing the template developer to quickly identify the offending regular expression.

I have found that some poorly written templates may have a line or lines that are syntactically correct but often result in a timeout when searching for a match. When this happens it may be hard to diagnose which line in the template is causing an issue.

Is this an issue worth addressing?

Closing because efficient timeouts are not available in python. Might see if there is a way to tackle the underlying problem or provide more verbose debug printouts.
