Can I embed something that looks like EL but isn't?

Gatling (Open-Source)
1

If I need a string to actually contain “${foo}” in a context where Gatling EL is used, is there something that I can do that will make Gatling return the actual string, instead of replacing with a non-existent session variable? Like escaping the $ sign or something?

2

Nope, we didn’t implement escaping. If it was to be done, it would be $${} (like Scala string interpolation). PR welcome :slight_smile:

Is there something like RawStringBody() which does NOT take a Gatling EL and returns a Body?

4

Nope. Believe it or not, you're the first one to ask.

Looking at the code, it looks like it should be a pretty straight-forward change. There is a line that looks like:

`
def elExpr: Parser[Part[Any]] = “${” ~> sessionObject <~ “}”

`

Which would need to be modified like so

def notEscaped: Parser[Part[Any]] = "(?<![$])" // or **(?:(?<=^)|(?<=[^$]))** def elExpr: Parser[Part[Any]] = notEscaped ~ "${" ~> sessionObject <~ "}"

Then add escapedExpr, something like this:

def escapedExpr: Parser[Part[Any]] = "$${[^}]*}" ^^ {_.substring(1)}

And obviously, amend the definition of the expression

`
def multivaluedExpr: Parser[List[Part[Any]]] = ( elExpr | escapedExpr | staticPart ).*

`

Look about right?

Sorry I can’t try it out and send a PR, I haven’t had time to set up to build Gatling as of yet. One of these days…

Not quite right, just realized I did not flag regex strings as such. Corrected below.

Come on. It's just a matter of cloning on Github and installing sbt. And
adding some tests in ELSpec.

Let me look into doing that this week. :slight_smile:

Would be much appreciated, thanks!
