mamba 0.4.0

A list-defined command-line parser with typed map inputs.

0.4.0

• Removed defaults from PairChoiceOption; paired groups are completed only by explicit member input.
• Made inherited option overrides resolve cardinality before typed map construction, preventing shadowed options from being resurrected.
• Made built-in help a defaulted global boolean parsed like other flags; the executor skips command execution when it is enabled.
• Validated synthesized negated flag spellings, reserved help aliases, and serialized positional/name namespaces consistently.
• Preserved every cleanup failure in callback order and broadened closed-pipe stdin detection.
• Replaced guessed numeric completion ranges with explicit completion metadata.

See MIGRATION.md for breaking-change guidance.

0.3.0

• Made Parser.parse return a sealed ParseOutcome: ParsedInvocation or parser-owned ParsedHelp.
• Made -h and --help exact parser tokens; help is not valid inside bundles.
• Rejected required choice inputs that declare defaults and empty choice sets.
• Enforced documented long/short option dash forms.
• Added paired default handling (superseded in 0.4.0, where pair members no longer accept defaults).
• Made ChoiceVariadic single-valued; use RepeatedChoiceVariadic for many trailing choices.
• Deep-froze and semantically strengthened RegistryMap; removed legacy description-only accessor maps.
• Added negated boolean flags to Carapace specs.
• Added MambaExecutionError to preserve non-recoverable primary and cleanup failures together.

See MIGRATION.md for breaking-change guidance.

0.2.0

• Added standalone PairedOptions groups with group-level description, required, and variant registered in their own list.
• Removed the legacy primary PairedOption types; pair members now resolve directly from their group.
• Missing required pair members are now reported by name.

0.1.0

• Added Carapace completion-spec conversion and platform-aware spec writing.
• Added validated, self-describing RegistryMap inputs for integrations.
• Added variadics, repeated positionals, persistent inputs, and nested command support across command registration, parsing, help, and integrations.
• Updated parser and command APIs to use list-defined input schemas.

0.0.1

• Restored the README from the pre-release revision.
• Repeated choice positionals now render one bounded Carapace positional slot per accepted value (times repetitions plus the original) instead of the unbounded positionalany field, which Mamba does not support.
• Variadics now validate only values after -- and no longer absorb extra ordinary positionals.
• Numeric options now complete a bounded default range of 0 to 1000 through $carapace.number.Range; doubles format money-style with at most two decimal places. String options and non-choice positionals and variadics complete $files by default.

0.0.0

• Added immutable, list-defined command and option schemas.

• Added typed flags, options, accessors, command groups, hooks, and help output.

• Added parsing and validation for typed, paired, repeatable, and inherited inputs.

• Tokens after -- are passed through as trailing arguments.

• Added PairString and OrString formatter values for paired-option help.

• Added PairedOption.variant for exactly-one | alternative groups.

• Added immutable, Yargs-inspired option and command schemas.

• Added Boolean and string options with aliases, defaults, choices, and validation.

• Added strict root command selection, command aliases, and nested command branches.

• Added dotted accessor options represented as immutable nested maps.

• Added required, optional, and discretionary named positional schemas.

• Added merged argument results and structured, non-throwing input errors.

• Added a JSON-backed task_list executable with add, delete, update, and list commands.

• Added Acanthis-backed validation for task titles and descriptions.
