v1.2.1

Patch Changes

• 3f20258: Add support for ISO 8601 basic format and bare hours in parseTimeString()

  New formats supported:

  1. ISO 8601 basic format (compact, no colons):
     • "1430" → 14:30
     • "143045" → 14:30:45
     • "143045.123" → 14:30:45.123
  2. Bare hours (defaults to :00 minutes):
     • "7" → 7:00
     • "7 AM" → 7:00 AM
     • "23" → 23:00

  The parser intelligently detects the format based on digit count and presence of colons, maintaining full backward compatibility with existing formats.

v1.2.0

Minor Changes

• e2b6e24: Add parseTimeString function for parsing standalone time strings in multiple formats (12h/24h, AM/PM, locale variations). Returns TimeAst compatible with Temporal.PlainTime. Handles common LLM-generated time formats like "09:00" alongside locale formats like "9:07 AM". Features LLM-friendly error messages with examples and suggestions.

v1.1.0

Minor Changes

• c557ac0: feat: Add support for BC dates (negative years in ISO 8601)

  Implement parsing and stringification of BC dates using ISO 8601 extended year format with negative year numbers. This follows the astronomical year numbering system where year 0 = 1 BC, year -1 = 2 BC, etc.

  Key features:

  • Parse BC dates with negative year notation: -0044-03-15 (44 BC)
  • Support year 0 representing 1 BC: 0000-01-01
  • Handle BC dates with time and timezone components
  • Proper year padding in output: -0044, -0001
  • Full round-trip compatibility

  Supported formats:

  • BC year only: -0100
  • BC year-month: -0753-04
  • BC full date: -0044-03-15
  • BC datetime: -0044-03-15T12:00:00
  • BC with timezone: -0044-03-15T12:00:00Z

  Examples:

  // Parse the Ides of March, 44 BC
  const bcDate = parseTemporal("-0044-03-15");
  // { kind: 'DateTime', date: { year: -44, month: 3, day: 15 }, ... }
  
  // Stringify BC date
  stringifyDate({ kind: "Date", year: -44, month: 3, day: 15 });
  // Returns: '-0044-03-15'
  
  // Year 0 represents 1 BC in ISO 8601
  parseTemporal("0000-01-01");
  // { kind: 'DateTime', date: { year: 0, month: 1, day: 1 }, ... }

  This implementation maintains full backward compatibility and follows ISO 8601:2004 extended year format specification.

• 7223124: feat: add comprehensive stringify API for AST serialization

  Add comprehensive stringify API for AST serialization. Implements full round-trip serialization support by converting parsed temporal ASTs back to ISO 8601/IXDTF formatted strings.

  New exports:

  • stringifyTemporal() - Main function for all temporal types
  • stringifyDate(), stringifyTime(), stringifyDateTime() - DateTime components
  • stringifyDuration(), stringifyRange() - Duration and Range types
  • stringifyOffset(), stringifyTimeZone(), stringifyAnnotation() - Supporting components

  Features:

  • Automatic normalization of offsets to canonical format (±HH:MM)
  • Component-based reconstruction for consistent output
  • Full round-trip compatibility with parser
  • Preserves all AST information including annotations and critical flags

  Example:

  import { parseTemporal, stringifyTemporal } from "@taskade/temporal-parser";
  
  const ast = parseTemporal("2025-01-12T10:00:00+0530"); // Compact format
  const normalized = stringifyTemporal(ast);
  // '2025-01-12T10:00:00+05:30' (canonical format)

Patch Changes

• 692b0f7: fix: Support comma as decimal separator in fractional seconds (European format)

  Add support for comma (,) as a decimal separator in fractional seconds for both time and duration components, as specified in ISO 8601. This enables parsing of European-formatted temporal strings while maintaining canonical dot (.) notation in serialized output.

  Supported formats:

  • Time with fractional seconds: T10:30:45,123 → T10:30:45.123
  • Duration with fractional seconds: PT1,5S → PT1.5S

  Behavior:

  • Parser accepts both . and , as decimal separators
  • Stringify normalizes all output to use . for consistency
  • Full round-trip compatibility maintained

  This change improves ISO 8601 compliance and enables parsing of temporal strings from European locales where comma is the standard decimal separator.

v1.0.5

Patch Changes

• 60b71d8: Enable npm provenance for trusted publishing. Adds NPM_CONFIG_PROVENANCE flag to use OIDC authentication instead of long-lived tokens.

v1.0.4

Patch Changes

• eb78e97: build(ci): pass GITHUB_TOKEN token to changesets release action
• 792e265: build(ci): Allow publishing to GitHub Packages by removing the hard-coded npmjs registry from publishConfig.

v1.0.2

Patch Changes

• 14c6355: build(ci): Fix GitHub Packages publish by skipping prepublishOnly script. The publish workflow now uses --ignore-scripts flag to prevent duplicate builds and avoid registry configuration conflicts.

v1.0.1

Patch Changes

• 7e2bb77: docs: add CHANGELOG.md with 1.0.0 release notes
• 5165f82: build(ci): Fix GitHub Packages publish workflow to use correct registry. Previously, the GitHub Packages publish step was attempting to publish to npm registry instead of GitHub Packages registry. This adds the explicit --registry flag to ensure packages are published to the correct location.
