\fBTcl_CreateObjCommand\fR defines a new command in \fIinterp\fR

.PP
.VS "info cmdtype feature"
\fBTcl_RegisterCommandTypeName\fR is used to associate a name (the
\fItypeName\fR argument) with a particular implementation function so that it
can then be looked up with \fBTcl_GetCommandTypeName\fR, which in turn is
called with a command token that information is wanted for and which returns
the name of the type that was registered for the implementation function used
for that command. (The lookup functionality is surfaced virtually directly in Tcl via
\fBinfo cmdtype\fR.) If there is no function registered for a particular
function, the result will be the string literal
.QW \fBnative\fR .
The registration of a name can be undone by registering a mapping to NULL
instead. The result from \fBTcl_GetCommandTypeName\fR will be exactly that
string which was registered, and not a copy; use of a compile-time constant
string is \fIstrongly recommended\fR.

\fBarray \fIoption arrayName\fR ?\fIarg arg ...\fR?
................................................................................
\fISearchId\fR indicates which search on \fIarrayName\fR to
check, and must have been the return value from a previous
invocation of \fBarray startsearch\fR.
This option is particularly useful if an array has an element
with an empty name, since the return value from
\fBarray nextelement\fR will not indicate whether the search
has been completed.
.TP
\fBarray default \fIsubcommand arrayName args...\fR
.VS TIP508
Manages the default value of the array. Arrays initially have no default
value, but this command allows you to set one; the default value will be
returned when reading from an element of the array \farrayName\fR if the read
would otherwise result in an error. Note that this may cause the \fBappend\fR,
\fBdict\fR, \fBincr\fR and \fBlappend\fR commands to change their behavior in
relation to non-existing array elements.
.RS
.PP
The \fIsubcommand\fR argument controls what exact operation will be performed
on the default value of \fIarrayName\fR. Supported \fIsubcommand\fRs are:
.VE TIP508
.TP
\fBarray default exists \fIarrayName\fR
.VS TIP508
This returns a boolean value indicating whether a default value has been set
for the array \fIarrayName\fR. Returns a false value if \fIarrayName\fR does
not exist. Raises an error if \fIarrayName\fR is an existing variable that is
not an array.
.VE TIP508
.TP
\fBarray default get \fIarrayName\fR
.VS TIP508
This returns the current default value for the array \fIarrayName\fR.  Raises
an error if \fIarrayName\fR is an existing variable that is not an array, or
if \fIarrayName\fR is an array without a default value.
.VE TIP508
.TP
\fBarray default set \fIarrayName value\fR
.VS TIP508
This sets the default value for the array \fIarrayName\fR to \fIvalue\fR.
Returns the empty string. Raises an error if \fIarrayName\fR is an existing
variable that is not an array, or if \fIarrayName\fR is an illegal name for an
array. If \fIarrayName\fR does not currently exist, it is created as an empty
array as well as having its default value set.
.VE TIP508
.TP
\fBarray default unset \fIarrayName\fR
.VS TIP508
This removes the default value for the array \fIarrayName\fR and returns the
empty string. Does nothing if \fIarrayName\fR does not have a default
value. Raises an error if \fIarrayName\fR is an existing variable that is not
an array.

.SH "SLOTTED DEFINITIONS"
Some of the configurable definitions of a class or object are \fIslotted
definitions\fR. This means that the configuration is implemented by a slot
object, that is an instance of the class \fBoo::Slot\fR, which manages a list
of values (class names, variable names, etc.) that comprises the contents of
the slot. The class defines three operations (as methods) that may be done on
the slot:
.TP
\fIslot\fR \fB\-append\fR ?\fImember ...\fR?
.
This appends the given \fImember\fR elements to the slot definition.
.TP
\fIslot\fR \fB\-clear\fR
.
This sets the slot definition to the empty list.










.TP
\fIslot\fR \fB\-set\fR ?\fImember ...\fR?
.
This replaces the slot definition with the given \fImember\fR elements.
.PP
A consequence of this is that any use of a slot's default operation where the
first member argument begins with a hyphen will be an error. One of the above
................................................................................
.QW \fBvariable\fR
slot, this is forwarded to
.QW "\fBmy \-append\fR" ),
and these methods which provide the implementation interface:
.TP
\fIslot\fR \fBGet\fR
.
Returns a list that is the current contents of the slot. This method must
always be called from a stack frame created by a call to \fBoo::define\fR or
\fBoo::objdefine\fR.









.TP


















\fIslot\fR \fBSet \fIelementList\fR
.
Sets the contents of the slot to the list \fIelementList\fR and returns the
empty string. This method must always be called from a stack frame created by
a call to \fBoo::define\fR or \fBoo::objdefine\fR.










.PP
The implementation of these methods is slot-dependent (and responsible for
accessing the correct part of the class or object definition). Slots also have
an unknown method handler to tie all these pieces together, and they hide
their \fBdestroy\fR method so that it is not invoked inadvertently. It is
\fIrecommended\fR that any user changes to the slot mechanism be restricted to
defining new operations whose names start with a hyphen.








.SH EXAMPLES
This example demonstrates how to use both forms of the \fBoo::define\fR and
\fBoo::objdefine\fR commands (they work in the same way), as well as
illustrating four of the subcommands of them.

.SH "SLOTTED DEFINITIONS"
Some of the configurable definitions of a class or object are \fIslotted
definitions\fR. This means that the configuration is implemented by a slot
object, that is an instance of the class \fBoo::Slot\fR, which manages a list
of values (class names, variable names, etc.) that comprises the contents of
the slot. The class defines five operations (as methods) that may be done on
the slot:
.TP
\fIslot\fR \fB\-append\fR ?\fImember ...\fR?
.
This appends the given \fImember\fR elements to the slot definition.
.TP
\fIslot\fR \fB\-clear\fR
.
This sets the slot definition to the empty list.
.TP
\fIslot\fR \fB\-prepend\fR ?\fImember ...\fR?
.VS TIP516
This prepends the given \fImember\fR elements to the slot definition.
.VE TIP516
.TP
\fIslot\fR \fB\-remove\fR ?\fImember ...\fR?
.VS TIP516
This removes the given \fImember\fR elements from the slot definition.
.VE TIP516
.TP
\fIslot\fR \fB\-set\fR ?\fImember ...\fR?
.
This replaces the slot definition with the given \fImember\fR elements.
.PP
A consequence of this is that any use of a slot's default operation where the
first member argument begins with a hyphen will be an error. One of the above
................................................................................
.QW \fBvariable\fR
slot, this is forwarded to
.QW "\fBmy \-append\fR" ),
and these methods which provide the implementation interface:
.TP
\fIslot\fR \fBGet\fR
.
Returns a list that is the current contents of the slot, but does not modify
the slot. This method must always be called from a stack frame created by a
call to \fBoo::define\fR or \fBoo::objdefine\fR. This method \fIshould not\fR
return an error unless it is called from outside a definition context or with
the wrong number of arguments.
.RS
.PP
.VS TIP516
The elements of the list should be fully resolved, if that is a meaningful
concept to the slot.
.VE TIP516
.RE
.TP
\fIslot\fR \fBResolve\fR \fIslotElement\fR
.VS TIP516
Returns \fIslotElement\fR with a resolution operation applied to it, but does
not modify the slot. For slots of simple strings, this is an operation that
does nothing, whereas for slots of classes, this maps a class name to its
fully-qualified class name.  This method must always be called from a stack
frame created by a call to \fBoo::define\fR or \fBoo::objdefine\fR.  This
method \fIshould not\fR return an error unless it is called from outside a
definition context or with the wrong number of arguments; unresolvable
arguments should be returned as is (as not all slot operations strictly
require that values are resolvable to work).
.RS
.PP
Implementations \fIshould not\fR enforce uniqueness and ordering constraints
in this method; that is the responsibility of the \fBSet\fR method.
.RE
.VE TIP516
.TP
\fIslot\fR \fBSet \fIelementList\fR
.
Sets the contents of the slot to the list \fIelementList\fR and returns the
empty string. This method must always be called from a stack frame created by
a call to \fBoo::define\fR or \fBoo::objdefine\fR. This method may return an
error if it rejects the change to the slot contents (e.g., because of invalid
values) as well as if it is called from outside a definition context or with
the wrong number of arguments.
.RS
.PP
This method \fImay\fR reorder and filter the elements if this is necessary in
order to satisfy the underlying constraints of the slot. (For example, slots
of classes enforce a uniqueness constraint that places each element in the
earliest location in the slot that it can.)
.RE
.PP
The implementation of these methods is slot-dependent (and responsible for
accessing the correct part of the class or object definition). Slots also have
an unknown method handler to tie all these pieces together, and they hide
their \fBdestroy\fR method so that it is not invoked inadvertently. It is
\fIrecommended\fR that any user changes to the slot mechanism be restricted to
defining new operations whose names start with a hyphen.
.PP
.VS TIP516
Most slot operations will initially \fBResolve\fR their argument list, combine
it with the results of the \fBGet\fR method, and then \fBSet\fR the result.
Some operations omit one or both of the first two steps; omitting the third
would result in an idempotent read-only operation (but the standard mechanism
for reading from slots is via \fBinfo class\fR and \fBinfo object\fR).
.VE TIP516
.SH EXAMPLES
This example demonstrates how to use both forms of the \fBoo::define\fR and
\fBoo::objdefine\fR commands (they work in the same way), as well as
illustrating four of the subcommands of them.

This appends the given string (or strings) to the value that the given
key maps to in the dictionary value contained in the given variable,
writing the resulting dictionary value back to that variable.
Non-existent keys are treated as if they map to an empty string. The
updated dictionary value is returned.





.TP

Return a new dictionary that contains each of the key/value mappings
listed as arguments (keys and values alternating, with each key being
followed by its associated value.)

................................................................................
This adds the given increment value (an integer that defaults to 1 if
not specified) to the value that the given key maps to in the
dictionary value contained in the given variable, writing the
resulting dictionary value back to that variable. Non-existent keys
are treated as if they map to 0. It is an error to increment a value
for an existing key if that value is not an integer. The updated
dictionary value is returned.

there to be no items to append to the list. It is an error for the
value that the key maps to to not be representable as a list. The
updated dictionary value is returned.





.TP
\fBdict map \fR{\fIkeyVariable valueVariable\fR} \fIdictionaryValue body\fR
.
This command applies a transformation to each element of a dictionary,
returning a new dictionary. It takes three arguments: the first is a

This operation takes the name of a variable containing a dictionary
value and places an updated dictionary value in that variable
containing a mapping from the given key to the given value. When
multiple keys are present, this operation creates or updates a chain
of nested dictionaries. The updated dictionary value is returned.

through nested dictionaries to the mapping to remove. At least one key
must be specified, but the last key on the key-path need not exist.
All other components on the path must exist. The updated dictionary

Execute the Tcl script in \fIbody\fR with the value for each \fIkey\fR

are silently discarded), even if the result of \fIbody\fR is an error
or some other kind of exceptional exit. The result of \fBdict
update\fR is (unless some kind of error occurs) the result of the
evaluation of \fIbody\fR.

.SH DESCRIPTION
.PP
This command treats the variable given by \fIvarName\fR as a list
and appends each of the \fIvalue\fR arguments to that list as a separate
element, with spaces between elements.
If \fIvarName\fR does not exist, it is created as a list with elements
given by the \fIvalue\fR arguments.






\fBLappend\fR is similar to \fBappend\fR except that the \fIvalue\fRs
are appended as list elements rather than raw text.
This command provides a relatively efficient way to build up
large lists.  For example,
.QW "\fBlappend a $b\fR"
is much more efficient than
.QW "\fBset a [concat $a [list $b]]\fR"

a mountable zip file system, that file system is mounted under \fIZIPROOT\fR\fB/app\fR.

.SH DESCRIPTION
\fBTclZipfs_AppHook()\fR is a utility function to perform standard
application initialization procedures. If the current application has
a mountable zip file system, that file system is mounted under \fIZIPROOT\fR\fB/app\fR.
If a file named \fBmain.tcl\fR is located in that file system, it is treated
as the startup script for the process. If the file \fIZIPROOT\fR\fB/app/tcl_library/init.tcl\fR
is present, \fBtcl_library\fR is set to  \fIZIPROOT\fR\fB/app/tcl_library.
.PP
On Windows, \fBTclZipfs_AppHook()\fR has a slightly different signature, it uses
WCHAR in stead of char. As a result, it only works if your application is compiled
using -DUNICODE.
.PP
If the \fBtcl_library\fR was not found in the application, the system will then search for it
as either a VFS attached to the application dynamic library, or as a zip archive named
libtcl_\fIMAJOR\fR_\fIMINOR\fR_\fIpatchLevel\fR.zip either in the present working directory
or in the standard tcl install location.
.PP
\fBTclzipfs_Mount()\fR mount the ZIP archive \fIzipname\fR on the mount
