Overview

Defined in the toys-core gem

A ToolDefinition describes a single command that can be invoked using Toys. It has a name, a series of one or more words that you use to identify the tool on the command line. It also has a set of formal flags and command line arguments supported, and a block that gets run when the tool is executed.

Instance Method Details

#add_acceptor(name, acceptor = nil, type_desc: nil, &block) ⇒ self

Parameters:

  • name (String)

    The name of the acceptor.

  • acceptor (Toys::Acceptor::Base, Object) (defaults to: nil)

    The acceptor to add. You can provide either an acceptor object, or a spec understood by Acceptor.create.

  • type_desc (String) (defaults to: nil)

    Type description string, shown in help. Defaults to the acceptor name.

  • block (Proc)

    Optional block used to create an acceptor. See Acceptor.create.

#add_completion(name, completion = nil, **options, &block) ⇒ self

Parameters:

  • name (String)

    The name of the completion.

  • completion (Proc, Toys::Completion::Base, Object) (defaults to: nil)

    The completion to add. You can provide either a completion object, or a spec understood by Completion.create.

#add_flag(key, flags = [], accept: nil, default: nil, handler: nil, complete_flags: nil, complete_values: nil, report_collisions: true, group: nil, desc: nil, long_desc: nil, display_name: nil) ⇒ self

Add a flag to the current tool. Each flag must specify a key which the script may use to obtain the flag value from the context. You may then provide the flags themselves in OptionParser form.

Parameters:

  • key (String, Symbol)

    The key to use to retrieve the value from the execution context.

  • flags (Array<String>) (defaults to: [])

    The flags in OptionParser format. If empty, a flag will be inferred from the key.

  • accept (Object) (defaults to: nil)

    An acceptor that validates and/or converts the value. You may provide either the name of an acceptor you have defined, or one of the default acceptors provided by OptionParser. Optional. If not specified, accepts any value as a string.

  • default (Object) (defaults to: nil)

    The default value. This is the value that will be set in the context if this flag is not provided on the command line. Defaults to nil.

  • handler (Proc, nil, :set, :push) (defaults to: nil)

    An optional handler for setting/updating the value. A handler is a proc taking two arguments, the given value and the previous value, returning the new value that should be set. You may also specify a predefined named handler. The :set handler (the default) replaces the previous value (effectively -> (val, _prev) { val }). The :push handler expects the previous value to be an array and pushes the given value onto it; it should be combined with setting default: [] and is intended for "multi-valued" flags.

  • complete_flags (Object) (defaults to: nil)

    A specifier for shell tab completion for flag names associated with this flag. By default, a Flag::DefaultCompletion is used, which provides the flag's names as completion candidates. To customize completion, set this to a hash of options to pass to the constructor for Flag::DefaultCompletion, or pass any other spec recognized by Completion.create.

  • complete_values (Object) (defaults to: nil)

    A specifier for shell tab completion for flag values associated with this flag. Pass any spec recognized by Completion.create.

  • report_collisions (Boolean) (defaults to: true)

    Raise an exception if a flag is requested that is already in use or marked as disabled. Default is true.

  • group (Toys::FlagGroup, String, Symbol, nil) (defaults to: nil)

    Group for this flag. You may provide a group name, a FlagGroup object, or nil which denotes the default group.

  • desc (String, Array<String>, Toys::WrappableString) (defaults to: nil)

    Short description for the flag. See #desc for a description of allowed formats. Defaults to the empty string.

  • long_desc (Array<String,Array<String>,Toys::WrappableString>) (defaults to: nil)

    Long description for the flag. See #long_desc for a description of allowed formats. Defaults to the empty array.

  • display_name (String) (defaults to: nil)

    A display name for this flag, used in help text and error messages.

Returns:

  • (self)

#add_flag_group(type: :optional, desc: nil, long_desc: nil, name: nil, report_collisions: true, prepend: false) ⇒ self

  • type (Symbol) (defaults to: :optional)

    The type of group. Default is :optional.

  • desc (String, Array<String>, Toys::WrappableString) (defaults to: nil)

    Short description for the group. See #desc for a description of allowed formats. Defaults to "Flags".

  • long_desc (Array<String,Array<String>,Toys::WrappableString>) (defaults to: nil)

    Long description for the flag group. See #long_desc for a description of allowed formats. Defaults to the empty array.

  • name (String, Symbol, nil) (defaults to: nil)

    The name of the group, or nil for no name.

  • report_collisions (Boolean) (defaults to: true)

    If true, raise an exception if a the given name is already taken. If false, ignore. Default is true.
