`build_vfs` mounts in reverse precedence (defaults first, site last overwrites). `DEFAULTS_PATH` resolved at compile time via `#directory`, so bundled templates ship inside the binary. Modules configured via `"modules": ["../path"]` in `thor.json` — each module contributes `layouts/` and `assets/` subdirectories.
|
||||
|

Three access patterns:
|
||||
- `vfs_get(vfs, path) -> ([]byte, bool)` — data only (lazy-loaded from disk)
|
||||
- `vfs_get_entry(vfs, path) -> (VFS_Entry, []byte, bool)` — entry + data (for callers that need `fs_path` for diagnostics)

## Open Graph
|
||||
|
||||
`Open_Graph` struct in `opengraph.odin` with fields ordered per [ogp.me](https://ogp.me/) spec. Site defaults set via `og_init(site)` (site_name, description, default image, locale). Page-specific fields via `og_for_page(site, page, base)` (copies base, overrides url/title/type/is_article/section/published_time). Templates access via `{{og.url}}`, `{{og.title}}`, `{{#og.is_article}}`, etc.
|
||||
`Open_Graph` struct in `opengraph.odin` with fields ordered per [ogp.me](https://ogp.me/) spec. `is_article` is `Maybe(bool)` — nil means "unset" (distinguished from explicitly `false`).
|
||||
|
||||
**Site-level** (`og_for_site`): starts from `Config_File.og` (user-supplied defaults from `thor.json`), then fills empty fields derivable from `Site`:
|
||||
- `site_name ← site.title`
|
||||
- `locale ← "en_US"` (default if unset)
|
||||
|
||||
**Page-level** (`og_for_page`): copies site OG, derives page-specific fields, then overlays `Page.og` (from frontmatter):
|
||||
- `url ← page.url`
|
||||
- `title ← page.title` (falls back to `site_name` if empty)
|
||||
- `type ← "article" if !page._is_index else "website"`
|
||||
- `is_article ← !page._is_index`
|
||||
- `section ← page.section`
|
||||
- `published_time / modified_time ← page.date / page.lastmod`
|
||||
- `description ← page.description`, else body summary (via `generate_summary`)
|
||||
|
||||
Paths through maps (e.g. `params.*`) are silently allowed — not validated. Templates access via `{{og.url}}`, `{{og.title}}`, `{{#og.is_article}}`, etc.

### Architecture
|
||||
|
||||
```
|
||||
parse(source) → tokenize → trim_standalone_whitespace → parse_section → Template
|
||||
parse(source, path) → tokenize → trim_standalone_whitespace → parse_section → Template
|
||||
render(tmpl, data, partials) → render_nodes (walks flat node array against context stack) → string
|
||||
```
|
||||
|
||||
- **Two-phase API**: `parse()` produces a reusable `Template`, `render()` walks it against data. Templates parsed once, rendered many times.
|
||||
- **Flat `[dynamic]Node` array** with `first_child`/`child_count` indices — pre-order layout.
|
||||
- **Flat `[dynamic]Node` array** with `children: []Node` slices (pre-order layout; slices point into the backing array). Each `Node` carries `pos: int` (byte offset into source) for diagnostics.
|
||||
- **`Template`** carries `source` and `path` — used by diagnostics to show file location and source context.
|
||||
- **Context stack**: `^[dynamic]any` with `append`/`pop` for section push/pop.
|
||||
- **`render_nodes` takes `Template` by value** (not `^Template`) — Odin's calling convention promotes to pointer when efficient. Eliminates "local copy" patterns at call sites.
|
||||
- **`Block_Override.source: Template`** — carries the template that defined the override, so warnings inside block overrides point at the correct file.
|
||||
- **`base_value`** peels Named/Distinct/Union layers (including `json.Value`). Also unwraps nested `any`-of-`any` (which occurs when `map[string]any` values are read via runtime map internals).
|
||||
- **`lookup_in`** resolves keys on structs (via `reflect.struct_field_value_by_name` with `allow_using = true`) and maps. Detects `Type_Info_Any` value kind in maps and reads the inner any directly to avoid double-wrap.
|
||||
- **Template inheritance**: `{{<parent}}` loads parent from partials, `{{$block}}` defines overridable sections. `merge_block_overrides` propagates overrides through multi-level chains.
|
||||
- **Dynamic partial names**: `{{>*key}}` resolves partial name from data context at render time.
|
||||
- **Render-time partial indentation**: `Indent_State` threads `at_line_start` through `render_nodes` so partial indent is applied at render time (via `write_indented` on Text nodes) instead of reparsing the partial's source. `render_template` writes initial indent, creates state, calls `render_nodes`. Data-injected newlines don't pick up indent (Variables don't update `at_line_start`).
|
||||
|
||||
### Diagnostics
|
||||
|
||||
Rust-style error messages with multi-line source context, caret underlines, and Levenshtein suggestions. ANSI colors via `core:terminal/ansi`, gated on `should_colorize()` (TTY detection on stderr).
|
||||
|
||||
**Error types**: `Error_Body{msg, pos, kind}` where `kind` is `Error_Kind.Syntax` (parse-time) or `Error_Kind.Data` (render-time). `Error` is a single-variant union wrapping `Error_Body` (nilable for `!= nil` / `or_return`).
|
||||
|
||||
**Strict-by-default warnings** — `render_nodes` emits `log.warnf` diagnostics for:
|
||||
- Unknown keys in `{{k}}`, `{{{k}}}`, `{{#k}}`, `{{^k}}` (via `validate_key_path` + `suggest_correction`)
|
||||
- Missing partials (`{{> name}}` not in partials map)
|
||||
- Missing parent templates (`{{<name}}` not in partials map)
|
||||
- Unmatched block overrides (`{{$name}}` doesn't match any block in parent template)
|
||||
|
||||
**Exceptions** (no warning):
|
||||
- `{{.}}` and dot-prefixed names (current context)
|
||||
- Paths that cross a map (e.g., `params.*` — user-defined namespace)
|
||||
- `Maybe(bool)` fields with nil value (field exists, value is nil — distinguished via `struct_has_field`)
|
||||
|
||||
**Block override source tracking**: `Block_Override.source: Template` ensures warnings inside block overrides point at the override's source file (e.g., `page.html`), not the parent template (`base.html`).

Formats an ISO 8601 date string as a display string. Takes a string, returns a string (e.g. `"2026-03-15T08:49:54-04:00"` → `"15 Mar 2026"`). Invalid input (empty, too-short, non-string, or unparseable) returns a `Data_Error`. Templates that need to skip dateless pages should gate with a section — `{{#date}}<time datetime="{{.}}">{{. | format}}</time>{{/date}}` — so the section's truthiness check catches empty before the filter runs. Commonly used inline as `{{date | format}}` to render a display string while keeping the raw ISO available via `{{date}}` for the `datetime=` attribute.
|
||||
|
||||
Internally: parses the invariant `YYYY-MM-DD` prefix by char offset, stringifies `time.Month(month_num)` and slices `[:3]` for the abbreviation. Accepts any of these ISO 8601 forms (the date prefix is what matters): `2023-10-15T13:18:50-07:00`, `2023-10-15T13:18:50-0700`, `2023-10-15T13:18:50Z`, `2023-10-15T13:18:50`, `2023-10-15`.
|
||||
|
||||
Future: will accept Go reference-date format strings (e.g. `{{date | format "Mon Jan 2 2006"}}`) and pull default format/timezone from site configuration.
|
||||
Takes an optional arg for the Go reference-date layout to use:
|
||||
- A double-quoted literal, spaces allowed: `{{date | format "Mon Jan 2 2006"}}`.
|
||||
- A bare key, resolved from context like any other field: `{{date | format long}}` uses the value of `long` (e.g. a site-config field) as the layout.
|
||||
- No arg: falls back to the `date_format` context key (typically `date.format` from `thor.json`).
