'\"
'\" The definitions below are for supplemental macros used in Tcl/Tk
'\" manual entries.
'\"
'\" .AP type name in/out ?indent?
'\"	Start paragraph describing an argument to a library procedure.
'\"	type is type of argument (int, etc.), in/out is either "in", "out",
'\"	or "in/out" to describe whether procedure reads or modifies arg,
'\"	and indent is equivalent to second arg of .IP (shouldn't ever be
'\"	needed;  use .AS below instead)
'\"
'\" .AS ?type? ?name?
'\"	Give maximum sizes of arguments for setting tab stops.  Type and
'\"	name are examples of largest possible arguments that will be passed
'\"	to .AP later.  If args are omitted, default tab stops are used.
'\"
'\" .BS
'\"	Start box enclosure.  From here until next .BE, everything will be
'\"	enclosed in one large box.
'\"
'\" .BE
'\"	End of box enclosure.
'\"
'\" .CS
'\"	Begin code excerpt.
'\"
'\" .CE
'\"	End code excerpt.
'\"
'\" .VS ?version? ?br?
'\"	Begin vertical sidebar, for use in marking newly-changed parts
'\"	of man pages.  The first argument is ignored and used for recording
'\"	the version when the .VS was added, so that the sidebars can be
'\"	found and removed when they reach a certain age.  If another argument
'\"	is present, then a line break is forced before starting the sidebar.
'\"
'\" .VE
'\"	End of vertical sidebar.
'\"
'\" .DS
'\"	Begin an indented unfilled display.
'\"
'\" .DE
'\"	End of indented unfilled display.
'\"
'\" .SO
'\"	Start of list of standard options for a Tk widget.  The
'\"	options follow on successive lines, in four columns separated
'\"	by tabs.
'\"
'\" .SE
'\"	End of list of standard options for a Tk widget.
'\"
'\" .OP cmdName dbName dbClass
'\"	Start of description of a specific option.  cmdName gives the
'\"	option's name as specified in the class command, dbName gives
'\"	the option's name in the option database, and dbClass gives
'\"	the option's class in the option database.
'\"
'\" .UL arg1 arg2
'\"	Print arg1 underlined, then print arg2 normally.

.SH NAME
delete \- delete things in the interpreter
.SH SYNOPSIS
\fBdelete \fIoption\fR ?\fIarg arg ...\fR?
.BE

.SH DESCRIPTION
.PP
The \fBdelete\fR command is used to delete things in the interpreter.
It is implemented as an ensemble, so extensions can add their own
options and extend the behavior of this command.  By default, the
\fBdelete\fR command handles the destruction of namespaces.
.PP
The \fIoption\fR argument determines what action is carried out
by the command.  The legal \fIoptions\fR (which may be abbreviated)
are:
.TP
\fBdelete class \fIname\fR ?\fIname...\fR?
Deletes one or more \fB[incr\ Tcl]\fR classes called \fIname\fR.
This deletes all objects in the class, and all derived classes
as well.
.sp
If an error is encountered while destructing an object, it will
prevent the destruction of the class and any remaining objects.
To destroy the entire class without regard for errors, use the
"\fBdelete namespace\fR" command.
.TP
\fBdelete object \fIname\fR ?\fIname...\fR?
Deletes one or more \fB[incr\ Tcl]\fR objects called \fIname\fR.
An object is deleted by invoking all destructors in its class
hierarchy, in order from most- to least-specific.  If all destructors
are successful, data associated with the object is deleted and
the \fIname\fR is removed as a command from the interpreter.
.sp
If the access command for an object resides in another namespace,
then its qualified name can be used:
.CS
delete object foo::bar::x
.CE
If an error is encountered while destructing an object, the
\fBdelete\fR command is aborted and the object remains alive.
To destroy an object without regard for errors, use the
"\fBrename\fR" command to destroy the object access command.
.TP
\fBdelete namespace \fIname\fR ?\fIname...\fR?
Deletes one or more namespaces called \fIname\fR.  This deletes
all commands and variables in the namespace, and deletes all
child namespaces as well.  When a namespace is deleted, it is
automatically removed from the import lists of all other namespaces.
