Can't parse a specific pattern

[Skarlso]

@NDuggan So sorry, was bogged down with a ton of stuff! This is next on my todo list now though. :)

[Skarlso]

What... even is that? :D

[Skarlso]

Oh it's a regex match against an element. Or at least something like a "%http%" in SQL and the likes. Hmmmmmm.....

[Skarlso]

The parsing kind of completely falls apart on this one. :/ Uh.

[Skarlso]

Alright, so I might be able to handle this gracefully, I think. Your pattern in that case would be something like /http/.match(@whatever. I'm using match to conform to ruby's regex match.

I wonder if this syntax is a standard that should be adopted? there is no standard reference other than the original https://goessner.net/articles/JsonPath/ and even there makes no mention of filters supporting regex

Looking at the Java implementation to support regex filter is also different: https://github.com/json-path/JsonPath

[Skarlso]

Yah, that's why I was reluctant to do it. It sort of messes things up a bit. :/ But I might implement it at one point anyways. :)

[Skarlso]

@khairihafsham It just dawned on my that I'm supporting regex in a query.

You could try ?(@name =~ /http[s]?/) or something like that.

@khairihafsham Yep. This actually works:
