Change default or set template settings in yml

[yslan]

I'm trying to inspect multiple solutions at the similar slices.
At one point, the yml file is mostly the duplicate information.

Is there a way to create a template function in yml file:

    <scene_template>:
      plots:
        p1:
          type: "pseudocolor"
          field: "temperature"
          pipeline: <pl_in>
          color_table:
            name: "Cool to Warm Extended"
          min_value: <cmin_in>
          max_value: <cmax_in>
      renders:
        r1:
          camera:
            position: [18.75, <y_in>+50.0, 0.0]
            look_at: [18.75, <y_in>+0.0, 0.0]
            up: [-1.0, 0.0, 0.0]
            zoom: 1.5
          image_prefix: "imgs/<fname_in>_y<y_in>_%06d"
          world_annotations: false
          screen_annotations: false
          image_width: 2048
          image_height: 2048

such that I can create new images like a function:

add_scene_template:
  name: s1
  pl_in: "pl4"
  y_in: 0
  cmin_in: 0.0
  cmax_in: 0.0

Or at lease being able to change the default.

    default_scene1:
      plots:
        p1:
          type: "pseudocolor"
          field: "temperature"
          pipeline: <pl_in>
          color_table:
            name: "Cool to Warm Extended"
      renders:
        r1:
          camera:
            position: [18.75, 50.0, 0.0]
            look_at: [18.75, 0.0, 0.0]
            up: [-1.0, 0.0, 0.0]
            zoom: 1.5
          world_annotations: false
          screen_annotations: false
          image_width: 2048
          image_height: 2048

so that we can only update the difference.

    s1:
      default: "default_scene1"
      plots:
        p1:
          min_value: 280.0
          max_value: 310.0
      renders:
        r1:
          image_prefix: "imgs/temp_y0_%06d"

Do we have something similar already?

Thanks!

@yslan, we do not have support for this.

These are good ideas of how we could support this - but I don't think we will have free energy to add custom templating support.

Many codes call ascent through a scripting interface that they can use to generate yaml.

I would suggest a templating tool like jinja, which can provide a nice workflow and with lots of features.
