ack 1.1.0

A simple validation library for Dart

1.1.0

Fixed

• Keep safeParse non-throwing when refinements or constraints throw recoverable Exceptions, while preserving Error values such as StateError so programming defects are not masked as validation failures.
• Decode RFC 3339 lowercase t/z separators in Ack.datetime(), which its own string validation already accepts (previously they failed at the decode step with a misleading "Codec decode failed" message).
• Bound direct, indirect, wrapper-mediated, and fluent-copy lazy-schema alias recursion (previously unbounded and prone to stack overflow).
• Snapshot factory collections so a caller mutating the passed list or map can no longer corrupt a constructed schema.
• Correct behavior-based schema and deep-collection equality.

Behavior changes

No public API changed (verified with dart_apitool against 1.0.1); the following now reject inputs that previously passed or misbehaved silently.

• Validate numeric multipleOf, IPv6, and RFC 3339 date-time values strictly. Announced leap seconds are preserved by Ack.string().datetime() but rejected by Ack.datetime(), where Dart cannot represent them. (migration: some previously-accepted strings and numbers now fail validation.)
• Reject invalid constraint configuration at construction — negative lengths/item counts, non-finite numeric bounds, min > max ranges, multipleOf <= 0, empty unions, empty or duplicate enum inputs, and unions that can yield nullable list items — all throw ArgumentError. (migration: fix the schema definition; put nullability on the list via Ack.list(item).nullable().)
• toJsonSchema() merges conflicting duplicate keywords into allOf and emits min/maxItems and min/maxProperties for exact counts. (migration: refresh snapshot or golden tests of exported schemas.)
• parse() throws AckException — instead of the raw callback error — when a constraint or refinement throws.

1.0.0-beta.12

Breaking Changes

• DoubleSchema and NumberSchema now reject non-finite values (NaN, Infinity, -Infinity) during runtime validation by default, aligning numeric schemas with JSON-safe values.
• Remove the retired JSON Schema DTO converter APIs.
• Replace the interim JSON Schema model kind API with sealed AckSchemaModel variants and canonical AckSchema.toSchemaModel() adapter conversion.

Added

• Ack.enumCodec<T extends Enum>(List<T> values) returns a CodecSchema<String, T> wrapping EnumSchema<T>. Use this when downstream code expects every value-shape to be a CodecSchema (e.g. a registry of codecs). Decode/encode are identity since EnumSchema already maps between T and the enum's .name.
• NumberSchemaExtensions adds fluent numeric constraints to Ack.number(): .min, .max, .greaterThan, .lessThan, .positive, .negative, and .multipleOf.

Changed

• Project discriminated schemas through union-owned discriminator branches.
• Preserve defaults, const values, extension keywords, transformed metadata, composition, and JSON Schema constraints through the schema model boundary.

Migration

• Re-run tests for code paths that parse or encode double/num values. If a boundary must accept NaN or infinities, model that value outside the JSON numeric schema path before validation.

1.0.0-beta.10

1.0.0-beta.7

• See release notes for details.

1.0.0-beta.6

Features

• Discriminated unions: Enforce Map-returning child schemas in discriminated unions (#67).
• Schema mapping API: Add AckSchema.parseAs and AckSchema.safeParseAs for validated-value mapping with consistent SchemaTransformError handling.

Improvements

• Schemas: Centralize null/default handling and extract ObjectSchema helpers (#65).

Bug Fixes

• Schemas: Fixes to schema correctness including transformed schema defaults and list unique items constraint (#50).

1.0.0-beta.5 - 2026-01-14

Features

• Equality: Implement value-based equality for schemas and constraints (#63). All schema and constraint classes now properly implement == and hashCode for structural comparison.

Improvements

• Dependencies: Updated meta and test dependencies to latest versions (#56).

1.0.0-beta.4 - 2025-12-29

Breaking Changes

• Format metadata: Reduced built-in format guidance to 7 core formats (email, uri, uuid, date, dateTime, ipv4, ipv6). Custom format strings are still supported via the format property.
• withDescription deprecated: Use describe() instead for setting schema descriptions.

Bug Fixes

• JSON Schema output: Now correctly adds null branch to anyOf/oneOf compositions when nullable: true, producing valid JSON Schema Draft-07 format.

Improvements

• DRY refactoring: Consolidated duplicate primitive schema parsers into one.
• Hardened schema type handling: Improved map validation and schema type handling.
• Consolidated JSON schema utilities: Reduced duplication across JSON schema utilities.
