The theme mode's editor (spec/14 §20, D-139): the theme a chart holds, as a node the
builder writes and as the %Visualize.Theme{} it draws as, and the panel that edits it.
The mode is the builder's shape while the open chart is a theme. Its writes are the
theme node of one site — the selected site, or the first of the chart that carries a
theme — and every one goes through change/3, a pure reading of one control's value,
so the panel and the tests agree on what a control means. The theme is drawn unchecked
— its fields over the default theme, no contract checked — so a theme that breaks a
contract still draws while a person fixes it, and the validity section says what breaks.
This module compiles only when Phoenix.Component is loaded (spec/10 §1.1, D-45, D-85).
Summary
Functions
The node with the ramp resampled at one more evenly spaced anchor, each the color the ramp had at its position (spec/14 §20.4): the ramp changes as little as the even spacing allows, and the new anchor is there to be moved.
The node without the ramp's anchor at i; a ramp keeps two anchors (spec/14 §20.4).
The node with one control's value written (spec/14 §20.2), or :error for a value that
does not read — a blank, a color Visualize.Color.parse/1 cannot read, a size that is
not a positive number — so the node is left as it was.
The node with every value of theme and the node's own name (spec/14 §20.2): a
variant starts from what it varies. A node with no name takes none, so a new theme does
not take a built-in theme's name by deriving from it.
The theme a site holds as the node the editor writes (spec/14 §20.1): a name as the whole node of the theme it names — built-in, else the store's — so an edit changes one value of the theme a person was looking at; a map as it is; anything else an empty node.
The %Visualize.Theme{} a design's theme value draws as (spec/14 §20.3): a built-in
name, the store's theme of that name, or a map over the default theme — built unchecked,
so a theme that breaks a contract still draws. Anything else is the default theme.
Renders the theme editor (spec/14 §20.2, §20.4, §20.5): derive from and the vision
select, then <form class="vis-builder-theme"> of sections — the theme's name, the
series, the chrome, the fonts, the ramps and the roles — then the theme's validity.
The node with one more series color: the default palette's color at the next position, cycling, so a new series is distinct from its neighbors.
The node without the series color at i; the last color stays (spec/08 §7.2).
