Version 14 of Creating Commands

Updated 2010-04-20 09:33:49 by lars_h

Tcl provides several commands which create commands and contexts within which scripts can be evaluated:

• [proc]
• [apply] creates an anonymous command
• [interp create] creates a named slave interp command
• [thread create] creates an opaque token associated with a thread
• [namespace ensemble] creates a namespace command from a namespace
• [class create] creates a named class command
• [$class create] creates an opaquely named object instance command
• [coroutine] creates a named coroutine command

generator	cmd?	#args	invocation	destructor
proc	yes	any	by name	rename $cmd ""
apply	no	any	by reference	implicit
interp create	yes	any	interp eval	$interp destroy, rename $interp ""
