`title` property not supported in DSL

[janslow]

First off, thanks for the effort you've put into this project, I've found it really useful!

However, I've been trying to use the view title property in the DSL, but I'm getting an "unexpected tokens error" (using v1.4.5).

Example

Input

workspace "Getting Started" "This is a model of my software system." {
    model {
        user = person "User" "A user of my software system."
        softwareSystem = softwareSystem "Software System" "My software system."

        user -> softwareSystem "Uses"
    }

    views {
        systemContext softwareSystem "SystemContext" "An example of a System Context diagram." {
            title "Foo"
            include *
            autoLayout
        }
    }
}

Reproduction Steps

structurizr-cli export -workspace /input.dsl -output /output --format json

Expected behaviour

CLI should finish successfully and write the workspace to /output/structurizr.json.

The input works fine at https://structurizr.com/dsl.

Actual Behaviour

Structurizr CLI v1.4.5
Exporting workspace from /input.dsl
 - loading workspace from DSL

I'm guessing the Structurizr DSL JAR just needs updating (I'd be happy to do this, if you're willing to review the PR, although it won't have a very reviewable diff 😄)

Thanks, yes, a new CLI release is due today/tomorrow that will include the recent DSL updates (including the title property).

[janslow]

Great, thanks for the quick response.

This is now supported in v1.5.0.
