- lexer: backtick raw text literal — content verbatim, no escape
processing, common source margin removed at lex time; `${ }` raw and
`{{ }}` auto-escaping holes
- `{{ e }}` desugars to `esc(${e})` in parser.ml — a Call on the `esc`
in scope, so types/owner/emit/.wob/VM are untouched
- WO-E004 unterminated raw literal; WO-E005 newline inside "..." —
closes a hole where a missing quote silently ate the rest of the file
- wo-html: `Component` interface, `render_all`, `Layout`, README
- framework: `ok_html` joins ok_text/ok_json in http/types.wo
- site + shop restructured to one-feature-one-module MVC (view +
controller per directory, model at the root, bootstrap-only main)
- removed the filler `pad: Int` convention — verified unnecessary for
plain classes, interface dispatch, containers and actors
- corrected recorded claims: gap #1 blocks neither the build nor the
layout; a class crosses module lines, only a free fn is scoped
- docs/guides/language-surface.md — the full grammar inventory
- story 37 landed and moved to done/
Gates: oop-accept MET, oop-e2e 116/0, woc-test 556/0, site 11/0,
web-app 46/0, fibers 10/0, db-actor 8/0

# site — how it is put together
|
|
|
|
Written 2026-08-23 with the sample's landing; restructured 2026-08-25
|
|
onto the program template's MVC layout (`docs/examples/shop`), so the two
|
|
samples now read the same way.
|
|
|
|
## The layout
|
|
|
|
| file | layer | what it owns |
|
|
| --- | --- | --- |
|
|
| `types.wo` | MODEL | the `Chapter` `@table`, the `ChapterLink` projection, `Chapters.links()`, and `seed_if_empty()` |
|
|
| `content.wo` | MODEL (content) | the nine chapter bodies as fragment-returning functions, plus `seed_chapters()` |
|
|
| `layout/app.wo` | VIEW (chrome) | `AppShell` — the component that fills wo-html's `Layout` — the two named widths, and `html_error` |
|
|
| `layout/header.wo`, `layout/footer.wo` | VIEW (chrome) | the shared nav bar and footer |
|
|
| `home/view.wo` | VIEW | `HomePage` and the homepage's code showcase |
|
|
| `home/controller.wo` | CONTROLLER | `Home` — the `/` handler |
|
|
| `chapter/view.wo` | VIEW | `ChapterNav`, `ChapterPage` |
|
|
| `chapter/controller.wo` | CONTROLLER | `ShowChapter` — the `/ch/:slug` handler |
|
|
| `admin/controller.wo` | CONTROLLER | `AdminEdit` — bearer-gated edit, answers a redirect (no view: it redirects) |
|
|
| `health/controller.wo` | CONTROLLER | `Health` — the liveness probe (no view: it answers text) |
|
|
| `main.wo` | BOOTSTRAP | seed, routes, serve. Nothing else |
|
|
| `wo.toml` | — | the two `[deps]`: `framework` (serving) and `html` (markup) |
|
|
|
|
One feature = one directory = one module, holding that feature's view
|
|
and its controller together. A module sees its own declarations plus
|
|
what it `use`s, so `home/` reaching the chapter nav has to say `use
|
|
chapter`.
|
|
|
|
The model stays at the root and is reachable from everywhere: a CLASS
|
|
crosses module lines without being exported, and only a free `fn` is
|
|
module-scoped (`WO-E210`). That single rule explains the whole layout —
|
|
`Chapter` and `ChapterLink` are classes, so the feature modules just
|
|
name them; the shared query would have been a free fn, so it is a
|
|
`static fn` on `Chapters` instead. (`pub` cannot prefix an `@table`
|
|
class — recorded gap #1 — but nothing needs it to.)
|
|
|
|
## Decisions that are not obvious from the code
|
|
|
|
- **Chapters are rows, not constants.** `seed_if_empty()` inserts them
|
|
only when the table answers empty, so a WAL restart keeps admin edits
|
|
instead of reseeding over them — the sample's own proof of chapter 6's
|
|
claim. The seed bodies are BUILT with wo-html's builders at boot; after
|
|
that the table is the truth and the builders are never consulted again.
|
|
- **The seam is enforced by where the query sits.** `Chapters.links()`
|
|
lives with the MODEL and hands the view a `multi ChapterLink` —
|
|
a projection, not a cursor. No component in this sample touches the
|
|
database, which is what lets `ChapterNav` be the same component on the
|
|
homepage and on every chapter page, differing only by `current`.
|
|
- **`HomePage` and `ChapterPage` hold a `Component`, not chapter data.**
|
|
The nav arrives as an already-built child component in a slot, so
|
|
neither page knows what a chapter is. That is content projection —
|
|
Angular's `<ng-content>`, with the slot as an ordinary field.
|
|
- **Two widths, named once.** `AppShell` carries a `container` field and
|
|
`layout/app.wo` exports `reading_shell` / `wide_shell`. The Tailwind
|
|
class strings appear in exactly one place instead of being repeated at
|
|
every call site.
|
|
- **Auth is handler-side by doctrine.** The framework ships mechanism
|
|
(`bearer_token`, constant-time `ct_eq`); which routes are gated and by
|
|
which token is policy, so `AdminEdit` checks its own field. No global
|
|
middleware — the public pages stay public.
|
|
- **`ok_html` is the framework's**, beside `ok_text`/`ok_json`: a status
|
|
line plus a content-type is transport, not rendering.
|
|
- **`\$` in chapter code samples.** Chapter sources show interpolation
|
|
(`${port}`) inside string literals of a language that interpolates —
|
|
the lexer's `\$` escape keeps them literal; `code_block()` then
|
|
HTML-escapes the result. This is also why those two samples stay
|
|
escaped `"..."` strings rather than becoming raw literals: a raw
|
|
literal has no escape character, so it cannot spell a literal `${`.
|
|
- **Concat spans lines two ways now.** A line ENDING in `..` continues on
|
|
the next (the one newline suppression in the language) — it never works
|
|
at the START of a line. For markup, prefer the backtick raw literal:
|
|
real newlines, real double-quoted attributes, source indentation
|
|
removed at compile time, `${ }` raw and `{{ }}` auto-escaping. The old
|
|
"`..` does not straddle newlines, so build accumulator-style" note is
|
|
obsolete and was removed.
|
|
- **wo-html's sheet is static.** Tailwind's class NAMES, one hand-written
|
|
CSS string inlined per page by `page()` — self-contained responses, no
|
|
toolchain; growing the sheet is appending a line in `tw_css()`.
|
|
|
|
Gate: `just site` — see `scripts/site-accept.sh` (11 checks; the restart
|
|
leg polls `/health` instead of sleeping, so it does not share
|
|
web-app-accept's 0.5s boot race).
