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).

|---|---|---|---|---|---|---|---|
| fn-abs | abs | builtins | builtin | abs | abs(a) -> int | The absolute value of an integer (its magnitude, never negative). | 8 |
Returns the magnitude of an integer, dropping its sign — so abs(-7) and abs(7) both give 7. It is handy for distance-style checks where direction does not matter, such as measuring how far two grid cells are apart along one axis before deciding whether something is "close enough". Combine two axis distances to build a simple proximity test. It takes a single integer and returns an integer.
Parameters:
a— the integer whose magnitude you want
program Proximity {
property Position { column: int = 0, row: int = 0 }
model Player { Position }
model Enemy { Position }
handler SpawnActors phase Start {
spawn Player { Position { column: 5, row: 5 } }
spawn Enemy { Position { column: 8, row: 6 } }
}
handler CheckAdjacency phase Update {
for (PlayerPosition) in query [Position, {Player}] {
for (EnemyPosition) in query [Position, {Enemy}] {
let column_gap = abs(PlayerPosition.column - EnemyPosition.column)
let row_gap = abs(PlayerPosition.row - EnemyPosition.row)
if column_gap + row_gap <= 1 { print(1) }
}
}
}
