Dynamically setting publishDir mode

[jrm5100]

Do closures only work if the entire directive is specified as a string?

Based on the documentation for dynamic directives I was hoping a closure would work for mode under the publishDir directive, but I get:

Invalid method invocation `setMode` with arguments:  (Script_a917c133$_runScript_closure1$_closure2) on PublishDir type

Here is my attempt:

publishDir params.output, mode: {move ? "move" : "symlink"}

with a val move that gets passed true or false under input.

I also tried putting the entire directive in a closure, but the module (as I'd expect) fails to compile.

I'm not sure you can use a closure there. However, you can go with plain Groovy and use this:

publishDir params.output, mode: "${move ? 'move' : 'symlink'}"

Thanks!

This suggested change should also allow you to use actual closures there: #2432
