0.7.0

Features

  • YAML parsing with automatic scalar type resolution (strings, integers, floats, booleans, null, hex, octal, infinity, NaN)
  • Block mappings and sequences with arbitrary nesting
  • Flow (inline) mappings {key: value} and sequences [1, 2, 3]
  • Quoted strings (single and double) with escape sequences
  • Block literal (|) and folded (>) scalars with chomping indicators
  • Multi-document support (---/... markers)
  • Anchors (&name) and aliases (*name)
  • Comment handling (full-line and inline)
  • YAML serialization in block and flow styles
  • Smart string quoting in output

[0.7.0] - 2026-03-01

Added

  • Added procedure specifications with inline (: ...) syntax, optional runtime checking via sigil-checks feature, and predicate combinators (any-of, maybe, list-of, none-of).

Fixed

  • Fixed false positive capture corruption check in serializer, Windows build issues with mingw macro collision and unix-connect, closure arity errors now catchable by guard, and exception handler double-pop segfault.
  • Fixed sigil docs api command and added procedure spec signatures to generated API documentation.
