min + max

Type: number

Signature: md.number().int().min(...).max(...)

What It Is

md.number().int().min(...).max(...) is used here as a contract-first parser powered by document-level structure checks, explicit section targeting, and typed field extraction for min max scenarios. With document(), section(), fields(), and number() in the schema, 1 h1 heading, 1 h2 section, and list content is converted into top-level keys meta without manual min max post-processing. Error cases report issue codes like missing_section, making operational diagnostics for min max flows consistent across local runs and CI.

When to Use

This method is a strong fit for typed markdown parsing with deterministic contracts where deterministic min max parsing matters more than free-form flexibility. Do not default to it for exploratory drafts that intentionally avoid strict validation around min max; the main cost is key-level strictness that improves typing but rejects ad-hoc variations. For best results, compose md.number().int().min(...).max(...) with document(), section(), fields(), and number() so min max schema intent stays readable and output remains predictable.

Schema

  meta: md.section('1. META').fields({
    Score: md.number().int().min(0).max(10),
  }),
})

Result

Success

{
  "success": true,
  "data": {
    "meta": {
      "Score": 7
    }
  }
}

Error

Failure trigger: The input violates one or more constraints declared in the schema; use issues[].path and issues[].code to locate the exact failing node.
