zensical-carve

Use Carve in a Zensical site, either as a block inside a Markdown page or as a complete .crv page.

pip install zensical-carve

Carve blocks in Markdown

Register a pymdownx.superfences custom fence in zensical.toml:

pymdownx.superfences.custom_fences = [
  { name = "mermaid", class = "mermaid", format = "pymdownx.superfences.fence_code_format" },
  { name = "carve", class = "carve", format = "zensical_carve.fence" },
]

The formatter uses a dot between the module and function. Zensical does not accept the module:function spelling here.

```carve
## Rendered by Carve

A *bold* and /italic/ line.
```

Complete Carve pages

Zensical does not discover .crv files as pages, so render them before the site build:

zensical-carve prepare
zensical build

After configuration changes, use the combined command so it passes --clean and avoids stale generated pages:

zensical-carve build

The converter writes a Markdown page beside each source. It returns headings and code blocks to Zensical as Markdown so the theme can build navigation, permalinks, syntax highlighting, and code controls. Other constructs remain Carve HTML to avoid a lossy whole-document Markdown conversion.

Frontmatter is copied to the generated page for Zensical to read.

Configuration

Settings may live in [tool.zensical-carve] inside zensical.toml or pyproject.toml:

[tool.zensical-carve]
extensions = ["details", "tabs", "math-block"]
emoji = "twemoji"
docs-dir = "docs"

An extension that takes options is written as an inline table, and lint = true reports lint findings while pages are prepared:

[tool.zensical-carve]
extensions = ["details", { wikilinks = { css_class = "wiki", new_window = true } }]
lint = true

Command-line flags override the file. Configuration also controls symbol maps, raw HTML, diagram prerendering, and the Kroki endpoint. The default public Kroki service receives diagram source; use a private endpoint when needed.

Lint

zensical-carve lint reports constructs that parse and render but not the way the author meant (a block attribute that attaches to nothing, a reference link with no definition) on every .crv page, and exits 1 when it finds any. With lint = true or --lint, prepare and build print the same findings as warnings, and zensical-carve build -- --strict stops before Zensical runs. Lint needs carve-lang 0.1.2 or newer.

Includes and build output

Includes are off by default. Enable them with includes = true or --includes; this requires carve-lang 0.1.4 or newer. Carve fences inside Markdown pages never expand includes. Generated pages record their source and a generated marker.

Feature support

Most Carve HTML works directly. Theme-sensitive constructs, diagrams, emoji, heading links, code blocks, and diff blocks receive specific adapters. See the feature matrix and collision measurements before enabling a large extension set.
