Expand description
A proportion, rendered as a bar.
The third phase-B emitter, beside form and
list. It is much the smallest, and it is here rather than in
the app because the trough it fills has been in phase A since before anything
could describe one: progress_rules emitted .progress and
.progress-fill[data-tone] for every tone while the only way to say “3 of 7”
was to concatenate it into a heading.
§What the pair buys, at the last layer
makeover_layout::Meter carries done and total rather than a percentage,
and the reason shows up here. A bar that is full because it landed exactly
and a bar that is full because it ran over are the same width and are not the
same fact, so the width is not allowed to be the only thing emitted.
§Neither number is divided here
--meter-done and --meter-total go out as themselves and progress_rules
does the arithmetic. That is the property the residual seam needs, and
chart states the reasoning in full: a residual is derived
once from stand-in values, so a number this crate WORKS OUT from two of them
is not a stand-in any filler can find, and one request’s percentage bakes
into the template. A number handed over whole stays a hole.
It also retires data-over. That flag existed because a percentage was the
only thing emitted, so the over-run had nowhere else to live; with both
integers in the markup the comparison is there to be read, and a stylesheet
that wants to react can make it where it uses it. Dropping it also clears a
collision: quasi-webview writes data-over="<selection>" on a control, and
goingson’s quasi-selection.js selects [data-over] blind.
What an over-run should look like stays app taste – goingson says it with
Tone::Danger – and a renderer that picked a stripe for everyone would be
decorating rather than describing.
