For Gantt, is it possible to override closed days for selected tasks?

Question

Using Gantt (which is wonderful like everything else in PlantUML)

Some tasks may be active over a weekend, e.g. a trade show, while most tasks should respect our weekend off.

Right now the saturday, sunday are closed makes a weekend tradeshow start the following Monday

It would be nice if days can be closed, then opened for a task(s) then closed again.

Or be able to specify a task ignores closed days.

Is this something I missed in the Language Reference, or if not this would be a feature request.

Answer 1

Good suggestion!

With last snapshot, you can now have this.

@startgantt
2020-07-07 to 2020-07-17 are closed
2020-07-13 is open

2020-07-14 is open for [Prototype design] 
2020-07-2 to 2020-07-4 are closed for [Prototype design] 

Project starts the 2020-07-01
[Prototype design] lasts 10 days
Then [Test prototype] lasts 10 days

[Foo] lasts 10 days

Are you expecting something like this?

We did not implement it for weekday but we can if this is useful for you.

Exactly what I was hoping for.

And implemented so fast! ... I never experienced such wonderful service before. Wow.

Is there a way to style the days closed for a given task? I am using this feature with default theme but the closed days are displayed as transparent in the task line, and I couldn't figure out a way to style it - tried closed { BackgroundColor... } but it doesn't seem to affect the closed days for a task, only the global closed days.

Either that or a way to style days off ("{foo} is off on ...}") for tasks assigned to a given resource.

Would also work if there is a way to style tasks paused ("[bar] is paused ...")
