5.0.0

This release splits the package into separate modules to help produce smaller binaries. Parsing and running commands are now separated, which allows for custom run types. This release includes the SuspendingCliktCommand and the ChainedCliktCommand, and it's easy to define your own.

See the migration guide for details on upgrading to Clikt 5.0.

Added

• Publish iosArm64 and iosX64 targets.
• Added NoSuchArgument exception that is thrown when too many arguments were given on the command line. Previously, a less specific UsageError was thrown instead.
• Added CommandLineParser.tokenize that splits a string into argv tokens.
• Added CommandLineParser that provides functions for parsing and finalizing commands manually for more control.
• Added Context.invokedSubcommands that contains all subcommands of the current command that are going to be invoked when allowMultipleSubcommands is true.
• Added SuspendingCliktCommand that has a suspend fun run method, allowing you to use coroutines in your commands.
• Added ChainedCliktCommand that allows you to return a value from your run method and pass it to the next command in the chain.
• Added Context.data as an alternative to obj that allows you to store more than one object in the context.
• Added Context.echoer to customize how echo messages are printed.
• Added CompletionGenerator to manually generate completions for a command.
• Added Context.exitProcess which you can use to prevent the process from exiting during tests.
• Added core module that supports watchOS, tvOS, and wasmWasi targets and has no dependencies.
• Added more options to CliktCommand.test to control the terminal interactivity. (#517)
• Added associate{}, associateBy{}, and associateWith{} transforms for options that allow you to convert the keys and values of the map. (#529)
• Added support for aliasing options to other options. (#535)
• Added limit and ignoreCase parameters to option().split(). (#541)
• Support calling --help on subcommands when parents have required parameters.

Changed

• In a subcommand with and an argument() with multiple() or optional(), the behavior is now the same regardless of the value of allowMultipleSubcommands: if a token matches a subcommand name, it's now treated as a subcommand rather than a positional argument.

• Due to changes to the internal parsing algorithm, the exact details of error messages when multiple usage errors occur have changed in some cases.

• Breaking Change: Moved the following parameters from CliktCommand's constructor; override the corresponding properties instead:

  removed parameter	replacement property
  help	fun help
  epilog	fun helpEpilog
  invokeWithoutSubcommand	val invokeWithoutSubcommand
  printHelpOnEmptyArgs	val printHelpOnEmptyArgs
  helpTags	val helpTags
  autoCompleteEnvvar	val autoCompleteEnvvar
  allowMultipleSubcommands	val allowMultipleSubcommands
  treatUnknownOptionsAsArgs	val treatUnknownOptionsAsArgs
  hidden	val hiddenFromHelp

• The following methods on CliktCommand have been renamed: commandHelp -> help, commandHelpEpilog -> epilog. The old names are deprecated.

• Breaking Change: CliktCommand.main and CliktCommand.parse are now extension functions rather than methods.

• Breaking Change: Context.obj and Context.terminal, and OptionTransformContext.terminal are now extension functions rather than properties.

• Breaking Change: The RenderedSection and DefinitionRow classes have moved to AbstractHelpFormatter.

• Markdown support in the help formatter is no longer included by default. To enable it, include the :clikt-markdown dependency and call yourCommand.installMordantMarkdown() before parsing.

• Updated Kotlin to 2.0.0

Fixed

• Fixed excess arguments not being reported when allowMultipleSubcommands=true and a subcommand has excess arguments followed by another subcommand.
• Commands with printHelpOnEmptyArgs=true will no longer print help if an option has a value from an environment variable or value source. (#382)

... (truncated)

Deprecated

• Deprecated Context.originalArgv. It will now always return an empty list. If your commands need an argv, you can pass it to them before you run them, or set in on the new Context.data map.
• Deprecated Context.expandArgumentFiles. Use Context.argumentFileReader instead.
