Proposal: New Reqex Expression

[B4rb4ross4]

The addition of an regex matching expression would be great. If I see it correct you can now only match literal strings with:

[?(@.title == "A string")]

I thought of something like:
[?(@.release =~ "/\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2}/"]

Hi Sven,

I could see that being useful :)

I've been looking around at comparable syntaxes in different languages and I see that yours is following after Ruby's ie. filename =~ /\.jpe?g$/

CSS has attribute selectors but the 'modifier/wildcard' symbol is always behind the equals sign ie. [filename*="jpg"]

I also wonder if tilde ~ is really the recognized symbol for Regex selection? Are there more examples?

Hi stephen,
I think I found this syntax in a Java-Implementation of Goessner JSONPath. https://github.com/jayway/JsonPath
It wasn't Ruby that I had on my mind. But I did some research and I think perl has the same syntax, which makes sense, because ruby was made as an improvement of Perl.

If this feature is wanted (is it?) I could provide a pr too if I have a spare day. We should just communicate, so we don't start both ;)

Hi Sven,

I've been really distracted by work!

I think the Java implementation looks sensible so following them should work for everyone :)

If you send a PR with one or two tests added then I'll try to merge it as soon as I can.

Thanks!

Has this ever been tackled? Looks not, which is kinda sad since most other JSONPath implementations allow this feature in one way or another.
