Make `---` divide cards, and stop drawing ASCII rules WML has no horizontal rule element -- its entire %layout entity is `<br>` -- so a thematic break was being rendered as `<p>------------</p>`, a hardcoded twelve-dash guess at screen width that wraps into nonsense on a narrow device and is short on a wide one. It was the one construct where the renderer invented a width out of nothing. A `---` already looks like a divider and reads as one in every Markdown document ever written, so it now is one: it starts a new card, by default. Rules are never drawn, whether or not they divide. Thematic breaks and `{.card Title}` markers are now a single mechanism -- an explicit divider, optionally carrying a title -- and compose freely in one document. Both still win over --split-level. A section takes its title from its own first heading when the divider does not supply one, so the common shape needs no titles at all: Intro on the menu. --- ## Weather Cold and clear. `--no-split-on-rule` / `split_on_rule: false` opts out of the splitting; it does not bring the dashes back. Three edges this opened, each fixed here rather than left to bite: - Setext headings. `Heading` over `---` is an H2 in Markdown, but the parser was ATX-only, so it produced a paragraph plus a rule. Once a rule divides cards, a setext document would have split at every heading and stranded each heading as body copy on the card before it. Setext headings are now parsed, so such a document keeps its structure. - Empty sections. A trailing `---`, or two in a row, produced an empty "Untitled" card and a menu entry leading to it. Sections with no renderable content are dropped. - The multi-card threshold was two sections, so a document with a single divider collapsed back into one card. Any explicit divider now makes a multi-card deck: `A --- B` asks for two screens. Also fixes a latent frontmatter bug this made far more likely: a document opening with `---` and no `key: value` lines had its opening swallowed as if the break were a frontmatter fence. A fenced block with no keys in it is not frontmatter. 222 tests. Rendering examples/trail.md still matches md2txt's committed output byte for byte; no golden file contains an ASCII rule any more.
