Description

Hello! The comment on line 11 yields a parsing error (// this comment yields error). I think it should not, or?

Steps to reproduce

1. Save code, and
2. render it using structurizr CLI

Code sample

workspace  {

    # directive to set all identifiers to be hierarchical
    !identifiers hierarchical 
    model {
        asystem = softwareSystem "System A" {
            fun1 = container "Container Fun 1"
        }
        bsystem = softwareSystem "System B" {
            joy1 = container "Container Joy 1"
            -> asystem "Callback" // this comment yields error
        }

        asystem -> bsystem "Calls" // works.
        asystem.fun1 -> bsystem.joy1

    }

    views {
        container bsystem "containers_sys_B" {
            include *
            autolayout lr
        }
    }

}

End of line comments are not currently supported I'm afraid. I've tagged the issue as an enhancement, but I have no plans to add support any time soon.

End of line comment works at line 14 in the same sample.

That is why I thought it would work. But its certainly a nitpick, there are bigger fishes to fry. 😊

It doesn't. 😀

Ahh, of course, foolish of me - I was sloppy when reviewing the results. Apologies! Thanks for taking the time to clarify Simon!
