Different default styles for taskgroup and task lines

[tomarney]

Great plugin, thanks! It works perfectly, but I'd love to able to write more concisely with some extra defaults.

I would like to have a default style for the taskgroup lines and a different default style for the task lines.

For thicker blue taskgroup lines and thinner gray tasks, using your example:

Current:

#timeliney.timeline(
  show-grid: true,
  line-style: (stroke: 6pt + blue), // changes everything
  {
    ...
    taskgroup(title: [*Research*], {
      task("Research the market", (0, 2), style: (stroke: 2pt + gray))
      task("Conduct user surveys", (1, 3), style: (stroke: 2pt + gray))
    })

    taskgroup(title: [*Development*], {
      task("Create mock-ups", (2, 3), style: (stroke: 2pt + gray))
      task("Develop application", (3, 5), style: (stroke: 2pt + gray))
      task("QA", (3.5, 6), style: (stroke: 2pt + gray))
    })
    ...
  }
)

Proposed:

#timeliney.timeline(
  show-grid: true,
  taskgroup-line-style: (stroke: 6pt + blue),
  task-line-style: (stroke: 2pt + gray),
  {
    ...
    taskgroup(title: [*Research*], {
      task("Research the market", (0, 2))
      task("Conduct user surveys", (1, 3))
    })

    taskgroup(title: [*Development*], {
      task("Create mock-ups", (2, 3))
      task("Develop application", (3, 5))
      task("QA", (3.5, 6))
    })
    ...
  }
)

I assume that, like in your example, a fairly standard use would be to have a strong color for the taskgroup and a lighter colour and slightly thinner line for the tasks. You could then just define one colour in the taskgroup function call:

taskgroup(title: [*Research*], color: red {
    task("Research the market", (0, 2))
    ...
})

taskgroup(title: [*Development*], color: blue {
    ...
})

and you could even default to applying one of typst's colormaps down the gantt chart (i.e., evenly space each taskgroup along the color map and assign all the tasks in that group to that color).

All of this will make reading, writing, editing, and getting started easier with your plugin. Though it's already great!

Thanks for the suggestion! I am currently busy both with a new job and finishing my master's thesis proposal (in which I will most definitely need to use this :P) so as soon as I have the time to work on this I will. Just wanted to drop a comment to reassure you that I'll take care of this eventually though!
