#notiz

A deterministic, strict Markdown parser in MoonBit, built on talcparsec.

notiz is not a CommonMark-conformant parser. It is a deliberately strict subset designed around a few principles:

#Strict semantics, not graceful degradation

Reserved characters are interpreted as syntax only when they form a complete construct. Once a reserved prefix appears, the parser commits to parsing that construct and errors if it is not well-formed — it does not silently fall back to treating the input as plain text. Malformed use of a reserved prefix is a hard error, not a fallback to text.

#Formatting markers are reserved, not punctuation

*, _, ` , $, \ are formatting markers. A bare or unclosed occurrence is a parse error: in formatted text such a character should be written as inline code or escaped, not exposed as special-looking plain text. Escape sequences (\*, \_, \` , \$, \\) produce a literal character; escaping any other character is an error.

#Link syntax [...](...) is not supported

The []() link syntax is not supported; [text] and [text](url) are kept as plain text. [ and ] are only special as the footnote reference prefix [^; a bare [ or ] is ordinary text. ! is ordinary punctuation, so an exclamation mark in prose is parsed as plain text.

#Determinism over backtracking

The grammar avoids backtracking: every construct starts with either a fixed atomic prefix or a character unique to that construct. Alternatives have disjoint first tokens, so each input has a single parse and there is no exponential blow-up on adversarial input such as runs of unclosed brackets.
