'\"
'\" 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
find \- search for classes and objects
.SH SYNOPSIS
\fBfind \fIoption\fR ?\fIarg arg ...\fR?
.BE

.SH DESCRIPTION
.PP
The \fBfind\fR command is used to find classes and objects
that are available in the current interpreter.  Classes and objects
are reported first in the active namespace, then in all other
namespaces in the interpreter.
.PP
The \fIoption\fR argument determines what action is carried out
by the command.  The legal \fIoptions\fR (which may be abbreviated)
are:
.TP
\fBfind classes ?\fIpattern\fR?
Returns a list of [incr Tcl] classes.  Classes in the current
namespace are listed first, followed by classes in all other
namespaces in the interpreter.  If the optional \fIpattern\fR
is specified, then the reported names are compared using the rules
of the "\fBstring match\fR" command, and only matching names are
reported.
.sp
If a class resides in the current namespace context, this command
reports its simple name--without any qualifiers.  However, if the
\fIpattern\fR contains \fB::\fR qualifiers, or if the class resides
in another context, this command reports its fully-qualified name.
Therefore, you can use the following command to obtain a list where
all names are fully-qualified:
.CS
find classes ::*
.CE
.TP
\fBfind objects ?\fIpattern\fR? ?\fB-class \fIclassName\fR? ?\fB-isa \fIclassName\fR?
Returns a list of [incr Tcl] objects.  Objects in the current
namespace are listed first, followed by objects in all other
namespaces in the interpreter.  If the optional \fIpattern\fR is
specified, then the reported names are compared using the rules
of the "\fBstring match\fR" command, and only matching names are
reported.
If the optional "\fB-class\fR" parameter is specified, this list is
restricted to objects whose most-specific class is \fIclassName\fR.
If the optional "\fB-isa\fR" parameter is specified, this list is
further restricted to objects having the given \fIclassName\fR
anywhere in their heritage.
.sp
If an object resides in the current namespace context, this command
reports its simple name--without any qualifiers.  However, if the
\fIpattern\fR contains \fB::\fR qualifiers, or if the object resides
in another context, this command reports its fully-qualified name.
Therefore, you can use the following command to obtain a list where
all names are fully-qualified:
.CS
find objects ::*
.CE
