Question on Pattern Matching

[Chetan Conikee]

Hi Jon

I stumbled on this issue and was wondering if I might be missing anything here

val s = """ { "name" : "bob" } """

//Works
Json.parse(s) match { case json""" { "name" : $n } """ => n }

//Does not work
Json.parse(s) match { case Json.parse(""" { "name" : $n } """) => n }

Am I missing anything here?

The reason I'd like to use this as I am building out generic function in order to substitute any pattern in 

Example:

val s = """ { "name" : "bob" } """

val attribute = "name"

val pattern = """ { """" + attribute + """" : $n }"""

Json.parse(s) match { case Json.parse(pattern) => n }

Would this be possible?

Hi Chetan,

I've replied to the GitHub issue here:

For your particular example, though, it's not going to work as nicely as you would like, but it's given me an idea for how this could be better supported.

In ordinary Scala, we can write:

   val Regex = """he(.*)o""".r
   "hello" match { case Regex(x) => x }

I'll have think about whether I could do something similar for JSON...

Thanks for the inspiration!

Cheers,
Jon
