NAME

       oo::util - Utility commands for TclOO

SYNOPSIS

       package require Tcl  8.5

       package require TclOO

       package require oo::util  ?1?

       mymethod method ?arg...?

_________________________________________________________________

DESCRIPTION

       This  package provides a convenience command for the easy specification of instance methods as callback commands, like timers, file events,
       Tk bindings, etc.

COMMANDS

       mymethod method ?arg...?
	      This command is available within instance methods. It takes a method name and, possibly, arguments for the method and returns a com-
	      mand  prefix which, when executed, will invoke the named method of the object we are in, with the provided arguments, and any others
	      supplied at the time of actual invokation.

	      Note: The command is equivalent to and named after the command provided by the OO package snit for the same purpose.

NAME

       lambda - Utility commands for anonymous procedures

SYNOPSIS

       package require Tcl  8.5

       package require lambda  ?1?

       ::lambda arguments body ?arg...?

       ::lambda@ namespace arguments body ?arg...?

_________________________________________________________________

DESCRIPTION

       This  package  provides	two convenience commands to make the writing of anonymous procedures, i.e. lambdas more proc-like. Instead of, for
       example, to write

		   set f {::apply {{x} {
		      ....
		   }}}

       with its deep nesting of braces, or

		   set f [list ::apply {{x y} {
		      ....
		   }} $value_for_x]

       with a list command to insert some of the arguments of a partial application, just write

		   set f [lambda {x} {
		      ....
		   }]

       and

		   set f [lambda {x y} {
		      ....
		   } $value_for_x]

COMMANDS

       ::lambda arguments body ?arg...?
	      The command constructs an anonymous procedure from the list of arguments, body script and (optional) predefined argument values  and
	      returns a command prefix representing this anonymous procedure.

	      When  invoked  the  body is run in a new procedure scope just underneath the global scope, with the arguments set to the values sup-
	      plied at both construction and invokation time.

       ::lambda@ namespace arguments body ?arg...?
	      The command constructs an anonymous procedure from the namespace name, list of arguments,  body  script  and  (optional)	predefined
	      argument values and returns a command prefix representing this anonymous procedure.

	      When  invoked  the body is run in a new procedure scope in the namespace, with the arguments set to the values supplied at both con-
	      struction and invokation time.
