docs / build-and-deploy (push) Successful in 2s
Rebuild the API Reference around one page per symbol and richer, verified content.
Pages & navigation
- One HTML page per symbol (kw-*, type-*, phase-*, screen-*, fn-*, annot-*, op-*)
instead of a single scrolling page; namespace overview pages (ns-screen …
ns-color) and a searchable index (api.html) with client-side fuzzy search.
- Sticky-header scroll offset (scroll-margin) so a jumped-to entry/param/color is
never hidden, plus a flash highlight on the scrolled-to target.
Deep linking in every snippet & example
- Namespace members split: `Screen`→namespace page, `fill_rectangle`→method page;
`Color`→palette page, `Charcoal`→its swatch — separately.
- Named arguments (`width:`) link to that parameter's anchor on the method page.
- Hover any token for a summary card built from the real API data (symbols.json).
Content & coverage
- Full authoritative surface documented from the compiler: every keyword, type,
the 6 phases (Start/Input/FixedUpdate/Update/LateUpdate/Render, each its own
page), all 22 annotations, namespace methods with parameter docs, builtins,
the world_* reflection ABI, networking, operators — 155 symbols.
- Longer, clearer explanations; "model"/"model instance" terminology, not "entity";
descriptive identifiers in every example (Position{column,row}, Velocity{delta_x,
delta_y}, Health{current,maximum}, Player/Enemy) — no Pos/Seg/x/dx.
- Accuracy fixes from compiler ground-truth: world_count() takes no arg,
world_query_next(property, cursor) arg order, event fields bind by name; dropped
`when` and `module` (not in the self-hosted parser).
Tooling
- inventory.json + check.py: coverage guard (every symbol has a page), duplicate-
token guard, and broken-link guard — fail CI so docs can't drift.
- validate.py: compiles every ```ludic example against bin/ludicc (158 compile).

Returns a random integer between <code>low</code> and <code>high</code>, inclusive of both ends — so <code>Random.range(low: 0, high: 3)</code> can return <code>0</code>, <code>1</code>, <code>2</code>, or <code>3</code>. Use it to place things randomly on a grid, pick from a list of options by index, or add jitter to positions and timers. The sequence is deterministic for a given seed, so call <code>Random.seed</code> first if you need reproducible runs. To pick a random <code>column</code> across a grid of width <code>GRID_WIDTH</code>, pass <code>high: GRID_WIDTH - 1</code>, since the last valid index is one less than the count.

Parameters:
|
|
- `low` — the smallest value that can be returned (inclusive)
|
|
- `high` — the largest value that can be returned (inclusive)
