Issue with expression

[sprotty]

The following regex comes from the chrome-manifest.json

When used with the following code it throws an exception (argument all_urls not found).
I'm no regex expert, but other online parsers validate it, so I assume its valid....

Fare.Xeger sut = new Fare.Xeger(regexString);
string result = sut.Generate();

^((\*|http|https|file|ftp|chrome-extension):\/\/(\*|\*\.[^\/\*]+|[^\/\*]+)?(\/.*))|<all_urls>$

Fare is a great piece of software and works on most test cases, thanks for all the effort.

Thank you for reporting this!

Project Fare turns Regular Expressions into Automatons by applying the algorithms of dk.brics.automaton and xeger.

Unfortunately, I don't have an answer to your question, as Project Fare is really a port of the above Java projects. – We'd have to try

^((\*|http|https|file|ftp|chrome-extension):\/\/(\*|\*\.[^\/\*]+|[^\/\*]+)?(\/.*))|<all_urls>$

in Java and compare the results.

You may use a different pattern or use a different engine to reverse the Regular Expression into an Automaton. As an example, you can use the Rex engine.
