Leniency

[charlesdecourval]

Hi,
how do I make the lib more lenient and not fail on a known json path that is missing ?
So , if in the code I'm expecting $.company.location.address and the address part is not in the json that I'm processing, how can I just ignore this and not fail ?
tks

That's not supported at the DSL level, but I believe it's a good idea that can be implemented in a future release.

For the moment the only way to do it, it's like this:

@Test
    fun `Assignments are working correctly with inner JSONs and lambdas`() {
        testFromDirectory("assign/jsoninjson") {
            "author" /= json {
                "fullName" /= {
                    sourceCtx().read("$.books[1].author")
                }
                "firstName" /= { targetCtx().read<String>("$.fullName").split(" ")[0] }
                "lastName" /= { targetCtx().read<String>("$.fullName").split(" ")[1] }
                - "fullName"
                "book" /= {
                    try {
                        sourceCtx().read("$.books[1].title1")
                    } catch (e: PathNotFoundException) {
                        ""
                    }
                }
                "address" /= json {
                    "country" /= "UK"
                }
            }
        }.doTest()
    }

You need to catch the exception PathNotFoundException:

"book" /= {
                    try {
                        sourceCtx().read("$.books[1].title1")
                    } catch (e: PathNotFoundException) {
                        ""
                    }
                }

Do you have any suggestions on how to implement this, from a design perspective?

After using the lib for most of the year, here's what we came up with, with success

fun MapNeat.assignHide(dest: String, src: String, log: Logger) {
  try {
    dest *= src
  } catch (exception: Exception) {
    log.warn(TransformerConstant.ERROR_PARSING + exception.message)
  }
}

But what would be nice would be an operator of the sort
/=? that would hide the exception
or
*=? that would do the same.

but over all, love the lib !

I've just saw your message. I will take this in consideration for the next release. Sorry for taking so long to respond, but I was quite busy with other assignments.
