.BE
.SH DESCRIPTION
.PP

These routines save the state of an interpreter before a call to a routine such
as \fBTcl_Eval\fR, and restore the state afterwards.

.PP

\fBTcl_SaveInterpState\fR saves the parts of \fIinterp\fR that comprise the

result of a script, including the resulting value, the return code passed as
\fIstatus\fR, and any options such as \fB\-errorinfo\fR and \fB\-errorcode\fR.
It returns a token for the saved state.  The interpreter result is not reset
and no interpreter state is changed.

.PP
\fBTcl_RestoreInterpState\fR restores the state indicated by \fIstate\fR and

returns the \fIstatus\fR originally passed in the corresponding call to

\fBTcl_SaveInterpState\fR.



.PP

If a saved state is not restored, \fBTcl_DiscardInterpState\fR must be called





to release it.  A token used to discard or restore state must not be used
again.
.PP
\fBTcl_SaveResult\fR, \fBTcl_RestoreResult\fR, and \fBTcl_DiscardResult\fR are





deprecated.  Instead use \fBTcl_SaveInterpState\fR,
\fBTcl_RestoreInterpState\fR, and \fBTcl_DiscardInterpState\fR, which are more

capable.
.PP

















\fBTcl_SaveResult\fR moves the result of \fIinterp\fR to the location
\fIstatePtr\fR points to and returns the interpreter result to its initial

state.  It does not save options such as \fB\-errorcode\fR or
\fB\-errorinfo\fR.
.PP
\fBTcl_RestoreResult\fR clears any existing result or error in \fIinterp\fR and
moves the result from \fIstatePtr\fR back to \fIinterp\fR.  \fIstatePtr\fR is

then in an undefined state and must not be used until passed again to
\fBTcl_SaveResult\fR.
.PP
\fBTcl_DiscardResult\fR releases the state stored at \fBstatePtr\fR, which is

then in an undefined state and must not be used until passed again to
\fBTcl_SaveResult\fR.
.PP


If a saved result is not restored, \fBTcl_DiscardResult\fR must be called to

release it.

.SH DESCRIPTION
.PP
These routines convert between UTF-8 strings and Unicode characters.  An
Unicode character represented as an unsigned, fixed-size
quantity.  A UTF-8 character is a Unicode character represented as
a varying-length sequence of up to \fBTCL_UTF_MAX\fR bytes.  A multibyte UTF-8
sequence consists of a lead byte followed by some number of trail bytes.
.PP
\fBTCL_UTF_MAX\fR is the maximum number of bytes that it takes to
represent one Unicode character in the UTF-8 representation.
.PP
\fBTcl_UniCharToUtf\fR stores the character \fIch\fR as a UTF-8 string
in starting at \fIbuf\fR.  The return value is the number of bytes stored
in \fIbuf\fR. If ch is an upper surrogate (range U+D800 - U+DBFF), then
the return value will be 0 and nothing will be stored. If you still
want to produce UTF-8 output for it (even though knowing it's an illegal
code-point on its own), just call \fBTcl_UniCharToUtf\fR again using ch = -1.
.PP
\fBTcl_UtfToUniChar\fR reads one UTF-8 character starting at \fIsrc\fR
and stores it as a Tcl_UniChar in \fI*chPtr\fR.  The return value is the
number of bytes read from \fIsrc\fR.  The caller must ensure that the
source buffer is long enough such that this routine does not run off the
end and dereference non-existent or random memory; if the source buffer
is known to be null-terminated, this will not happen.  If the input is

characters.
.PP
\fBTcl_UtfCharComplete\fR returns 1 if the source UTF-8 string \fIsrc\fR
of \fIlength\fR bytes is long enough to be decoded by
\fBTcl_UtfToUniChar\fR, or 0 otherwise.  This function does not guarantee
that the UTF-8 string is properly formed.  This routine is used by
procedures that are operating on a byte at a time and need to know if a
full Unicode character has been seen.
.PP
\fBTcl_NumUtfChars\fR corresponds to \fBstrlen\fR for UTF-8 strings.  It
returns the number of Tcl_UniChars that are represented by the UTF-8 string
\fIsrc\fR.  The length of the source string is \fIlength\fR bytes.  If the
length is negative, all bytes up to the first null byte are used.
.PP
\fBTcl_UtfFindFirst\fR corresponds to \fBstrchr\fR for UTF-8 strings.  It
returns a pointer to the first occurrence of the Unicode character \fIch\fR
in the null-terminated UTF-8 string \fIsrc\fR.  The null terminator is
considered part of the UTF-8 string.
.PP
\fBTcl_UtfFindLast\fR corresponds to \fBstrrchr\fR for UTF-8 strings.  It
returns a pointer to the last occurrence of the Unicode character \fIch\fR
in the null-terminated UTF-8 string \fIsrc\fR.  The null terminator is
considered part of the UTF-8 string.
.PP
Given \fIsrc\fR, a pointer to some location in a UTF-8 string,
\fBTcl_UtfNext\fR returns a pointer to the next UTF-8 character in the
string.  The caller must not ask for the next character after the last
character in the string if the string is not terminated by a null

.SH NAME
oo::abstract \- a class that does not allow direct instances of itself
.SH SYNOPSIS

.SH "CLASS HIERARCHY"

.fi
.BE
.SH DESCRIPTION
Abstract classes are classes that can contain definitions, but which cannot be
directly manufactured; they are intended to only ever be inherited from and
instantiated indirectly. The characteristic methods of \fBoo::class\fR
(\fBcreate\fR and \fBnew\fR) are not exported by an instance of
\fBoo::abstract\fR.
.PP
Note that \fBoo::abstract\fR is not itself an instance of \fBoo::abstract\fR.
.SS CONSTRUCTOR
The \fBoo::abstract\fR class does not define an explicit constructor; this
means that it is effectively the same as the constructor of the
\fBoo::class\fR class.
.SS DESTRUCTOR
The \fBoo::abstract\fR class does not define an explicit destructor;
destroying an instance of it is just like destroying an ordinary class (and
will destroy all its subclasses).
.SS "EXPORTED METHODS"
The \fBoo::abstract\fR class defines no new exported methods.
.SS "NON-EXPORTED METHODS"
The \fBoo::abstract\fR class explicitly states that \fBcreate\fR,
\fBcreateWithNamespace\fR, and \fBnew\fR are unexported.
.SH EXAMPLES
.PP
This example defines a simple class hierarchy and creates a new instance of
it. It then invokes a method of the object before destroying the hierarchy and
showing that the destruction is transitive.

.TH callback n 0.3 TclOO "TclOO Commands"

'\" Note:  do not modify the .SH NAME line immediately below!
.SH NAME
callback, mymethod \- generate callbacks to methods
.SH SYNOPSIS
.nf
package require TclOO

\fBcallback\fR \fImethodName\fR ?\fIarg ...\fR?
\fBmymethod\fR \fImethodName\fR ?\fIarg ...\fR?
.fi
.BE
.SH DESCRIPTION
The \fBcallback\fR command,
'\" Based on notes in the tcllib docs, we know the provenance of mymethod
also called \fBmymethod\fR for compatibility with the ooutil and snit packages
of Tcllib,
and which should only be used from within the context of a call to a method
(i.e. inside a method, constructor or destructor body) is used to generate a
script fragment that will invoke the method, \fImethodName\fR, on the current
object (as reported by \fBself\fR) when executed. Any additional arguments
provided will be provided as leading arguments to the callback. The resulting
script fragment shall be a proper list.
.PP
Note that it is up to the caller to ensure that the current object is able to
handle the call of \fImethodName\fR; this command does not check that.
\fImethodName\fR may refer to any exported or unexported method, but may not
refer to a private method as those can only be invoked directly from within
methods. If there is no such method present at the point when the callback is
invoked, the standard \fBunknown\fR method handler will be called.
.SH EXAMPLE
This is a simple echo server class. The \fBcallback\fR command is used in two
places, to arrange for the incoming socket connections to be handled by the
\fIAccept\fR method, and to arrange for the incoming bytes on those
connections to be handled by the \fIReceive\fR method.

\fBclassvariable\fR \fIvariableName\fR ?\fI...\fR?
.fi
.BE
.SH DESCRIPTION
The \fBclassvariable\fR command is available within methods. It takes a series
of one or more variable names and makes them available in the method's scope;
those variable names must not be qualified and must not refer to array
elements. The originating scope for the variables is the namespace of the
class that the method was defined by. In other words, the referenced variables
are shared between all instances of that class.
.PP
Note: This command is equivalent to the command \fBtypevariable\fR provided by
the snit package in tcllib for approximately the same purpose. If used in a
method defined directly on a class instance (e.g., through the
\fBoo::objdefine\fR \fBmethod\fR definition) this is very much like just
using:
.PP

If a format string lacks a \fB%z\fR or \fB%Z\fR format group,
it is possible for the time to be ambiguous because it appears twice
in the same day, once without and once with Daylight Saving Time.
If this situation occurs, the first occurrence of the time is chosen.
(For this reason, it is wise to have the input string contain the
time zone when converting local times.  This caveat does not apply to
UTC times.)
.PP
If the interpretation of the groups yields an impossible time because
a field is out of range, enough of that field's unit will be added to
or subtracted from the time to bring it in range. Thus, if attempting to
scan or format day 0 of the month, one day will be subtracted from day
1 of the month, yielding the last day of the previous month.
.PP
If the interpretation of the groups yields an impossible time because
a Daylight Saving Time change skips over that time, or an ambiguous
time because a Daylight Saving Time change skips back so that the clock
observes the given time twice, and no time zone specifier (\fB%z\fR
or \fB%Z\fR) is present in the format, the time is interpreted as
if the clock had not changed.

Note that the current escape resp. quoting of arguments for windows works only
with executables using CommandLineToArgv, CRT-library or similar, as well as

Although it is the common escape algorithm, but, in fact, the way how the
executable parses the command-line (resp. splits it into single arguments)
is decisive.
.PP
Unfortunately, there is currently no way to supply newline character within
an argument to the batch files (\fB.cmd\fR or \fB.bat\fR) or to the command

.SH DESCRIPTION
.PP
The \fBhttp\fR package provides the client side of the HTTP/1.1
protocol, as defined in RFC 7230 to RFC 7235, which supersede RFC 2616.
The package implements the GET, POST, and HEAD operations
of HTTP/1.1.  It allows configuration of a proxy host to get through
firewalls.  The package is compatible with the \fBSafesock\fR security
policy, so it can be used by untrusted applets to do URL fetching from
a restricted set of hosts. This package can be extended to support
additional HTTP transport protocols, such as HTTPS, by providing
a custom \fBsocket\fR command, via \fB::http::register\fR.

\fB\-accept\fR \fImimetypes\fR
.
The Accept header of the request.  The default is */*, which means that
all types of documents are accepted.  Otherwise you can supply a
comma-separated list of mime type patterns that you are
willing to receive.  For example,
.QW "image/gif, image/jpeg, text/*" .
.TP
\fB\-pipeline\fR \fIboolean\fR
.
Specifies whether HTTP/1.1 transactions on a persistent socket will be
pipelined.  See the \fBPERSISTENT SOCKETS\fR section for details. The default
is 1.
.TP
\fB\-postfresh\fR \fIboolean\fR
.
Specifies whether requests that use the \fBPOST\fR method will always use a
fresh socket, overriding the \fB-keepalive\fR option of
command \fBhttp::geturl\fR.  See the \fBPERSISTENT SOCKETS\fR section for details.
The default is 0.
.TP
\fB\-proxyhost\fR \fIhostname\fR
.
The name of the proxy host, if any.  If this value is the
empty string, the URL host is contacted directly.
.TP
\fB\-proxyport\fR \fInumber\fR

to determine if a proxy is required for a given host.  One argument, a
host name, is added to \fIcommand\fR when it is invoked.  If a proxy
is required, the callback should return a two-element list containing
the proxy server and proxy port.  Otherwise the filter should return
an empty list.  The default filter returns the values of the
\fB\-proxyhost\fR and \fB\-proxyport\fR settings if they are
non-empty.
.TP
\fB\-repost\fR \fIboolean\fR
.
Specifies what to do if a POST request over a persistent connection fails
because the server has half-closed the connection.  If boolean \fBtrue\fR, the
request
will be automatically retried; if boolean \fBfalse\fR it will not, and the
application
that uses \fBhttp::geturl\fR is expected to seek user confirmation before
retrying the POST.  The value \fBtrue\fR should be used only under certain
conditions. See the \fBPERSISTENT SOCKETS\fR section for details. The
default is 0.
.TP
\fB\-urlencoding\fR \fIencoding\fR
.
The \fIencoding\fR used for creating the x-url-encoded URLs with
\fB::http::formatQuery\fR and \fB::http::quoteString\fR.
The default is \fButf-8\fR, as specified by RFC
2718.  Prior to http 2.5 this was unspecified, and that behavior can be
returned by specifying the empty string (\fB{}\fR), although
\fIiso8859-1\fR is recommended to restore similar behavior but without the
\fB::http::formatQuery\fR or \fB::http::quoteString\fR
throwing an error processing non-latin-1 characters.
.TP
\fB\-useragent\fR \fIstring\fR
.
The value of the User-Agent header in the HTTP request.  In an unsafe
interpreter, the default value depends upon the operating system, and
the version numbers of \fBhttp\fR and \fBTcl\fR, and is (for example)
.QW "\fBMozilla/5.0 (Windows; U; Windows NT 10.0) http/2.8.12 Tcl/8.6.8\fR" .
A safe interpreter cannot determine its operating system, and so the default
in a safe interpreter is to use a Windows 10 value with the current version
numbers of \fBhttp\fR and \fBTcl\fR.
.TP
\fB\-zip\fR \fIboolean\fR
.
If the value is boolean \fBtrue\fR, then by default requests will send a header
.QW "\fBAccept-Encoding: gzip,deflate,compress\fR" .
If the value is boolean \fBfalse\fR, then by default this header will not be sent.
In either case the default can be overridden for an individual request by
supplying a custom \fBAccept-Encoding\fR header in the \fB-headers\fR option
of \fBhttp::geturl\fR. The default is 1.
.RE
.TP
\fB::http::geturl\fR \fIurl\fR ?\fIoptions\fR?
.
The \fB::http::geturl\fR command is the main procedure in the package.
The \fB\-query\fR option causes a POST operation and
the \fB\-validate\fR option causes a HEAD operation;

Pragma: no-cache
.CE
.RE
.TP
\fB\-keepalive\fR \fIboolean\fR
.

multiple requests.  Default is 0.
.TP
\fB\-method\fR \fItype\fR
.
Force the HTTP request method to \fItype\fR. \fB::http::geturl\fR will
auto-select GET, POST or HEAD based on other options, but this option
enables choices like PUT and DELETE for webdav support.

\fB::http::formatQuery\fR \fIkey value\fR ?\fIkey value\fR ...?
.
This procedure does x-url-encoding of query data.  It takes an even
number of arguments that are the keys and values of the query.  It
encodes the keys and values, and generates one string that has the
proper & and = separators.  The result is suitable for the
\fB\-query\fR value passed to \fB::http::geturl\fR.
.TP
\fB::http::quoteString\fR \fIvalue\fR
.
This procedure does x-url-encoding of string.  It takes a single argument and
encodes it.
.TP
\fB::http::reset\fR \fItoken\fR ?\fIwhy\fR?
.
This command resets the HTTP transaction identified by \fItoken\fR, if any.
This sets the \fBstate(status)\fR value to \fIwhy\fR, which defaults to
\fBreset\fR, and then calls the registered \fB\-command\fR callback.

error. The command is useful when a registered protocol detects an problem
(for example, an invalid TLS certificate) that will cause an error to

precise error message rather than a general one.  The command returns the
value provided by the last call with argument \fImessage\fR, or the empty

.PP
See RFC 7230 Sec 6, which supersedes RFC 2616 Sec 8.1.
.PP
A persistent connection allows multiple HTTP/1.1 transactions to be
carried over the same TCP connection.  Pipelining allows a
client to make multiple requests over a persistent connection without
waiting for each response.  The server sends responses in the same order
that the requests were received.
.PP
If a POST request fails to complete, typically user confirmation is
needed before sending the request again.  The user may wish to verify
whether the server was modified by the failed POST request, before
sending the same request again.
.PP
A HTTP request will use a persistent socket if the call to
\fBhttp::geturl\fR has the option \fB-keepalive true\fR. It will use
pipelining where permitted if the \fBhttp::config\fR option
\fB-pipeline\fR is boolean \fBtrue\fR (its default value).
.PP
The http package maintains no more than one persistent connection to each
server (i.e. each value of
.QW "domain:port" ).
If \fBhttp::geturl\fR is called to make a request over a persistent
connection while the connection is busy with another request, the new
request will be held in a queue until the connection is free.
.PP
The http package does not support HTTP/1.0 persistent connections
controlled by the \fBKeep-Alive\fR header.
.SS "SPECIAL CASES"
.PP
This subsection discusses issues related to closure of the
persistent connection by the server, automatic retry of failed requests,
the special treatment necessary for POST requests, and the options for
dealing with these cases.
.PP
In accordance with RFC 7230, \fBhttp::geturl\fR does not pipeline
requests that use the POST method.  If a POST uses a persistent
connection and is not the first request on that connection,
\fBhttp::geturl\fR waits until it has received the response for the previous
request; or (if \fBhttp::config\fR option \fB-postfresh\fR is boolean \fBtrue\fR) it
uses a new connection for each POST.
.PP
If the server is processing a number of pipelined requests, and sends a
response header
.QW "\fBConnection: close\fR"
with one of the responses (other than the last), then subsequent responses
are unfulfilled. \fBhttp::geturl\fR will send the unfulfilled requests again
over a new connection.
.PP
A difficulty arises when a HTTP client sends a request over a persistent
connection that has been idle for a while.  The HTTP server may
half-close an apparently idle connection while the client is sending a
request, but before the request arrives at the server: in this case (an
.QW "asynchronous close event" )
the request will fail.  The difficulty arises because the client cannot
be certain whether the POST modified the state of the server.  For HEAD or
GET requests, \fBhttp::geturl\fR opens another connection and retransmits
the failed request. However, if the request was a POST, RFC 7230 forbids
automatic retry by default, suggesting either user confirmation, or
confirmation by user-agent software that has semantic understanding of
the application.  The \fBhttp::config\fR option \fB-repost\fR allows for
either possibility.
.PP
Asynchronous close events can occur only in a short interval of time.  The
\fBhttp\fR package monitors each persistent connection for closure by the
server.  Upon detection, the connection is also closed at the client end,
and subsequent requests will use a fresh connection.
.PP
If the \fBhttp::geturl\fR command is called with option \fB-keepalive true\fR,
then it will both try to use an existing persistent connection
(if one is available), and it will send the server a
.QW "\fBConnection: keep-alive\fR"
request header asking to keep the connection open for future requests.
.PP
The \fBhttp::config\fR options \fB-pipeline\fR, \fB-postfresh\fR, and
\fB-repost\fR relate to persistent connections.
.PP
Option \fB-pipeline\fR, if boolean \fBtrue\fR, will pipeline GET and HEAD requests
made
over a persistent connection.  POST requests will not be pipelined - if the
POST is not the first transaction on the connection, its request will not
be sent until the previous response has finished.  GET and HEAD requests
made after a POST will not be sent until the POST response has been

.PP
Option \fB-postfresh\fR, if boolean \fBtrue\fR, will override the \fBhttp::geturl\fR option
\fB-keepalive\fR, and always open a fresh connection for a POST request.
.PP
Option \fB-repost\fR, if \fBtrue\fR, permits automatic retry of a POST request
that fails because it uses a persistent connection that the server has
half-closed (an
.QW "asynchronous close event" ).
Subsequent GET and HEAD requests in a failed pipeline will also be retried.
\fIThe -repost option should be used only if the application understands
that the retry is appropriate\fR - specifically, the application must know
that if the failed POST successfully modified the state of the server, a repeat POST
would have no adverse effect.

.SH NAME
link \- create link from command to method of object
.SH SYNOPSIS
.nf
package require TclOO

\fBlink\fR \fImethodName\fR ?\fI...\fR?
\fBlink\fR \fB{\fIcommandName methodName\fB}\fR ?\fI...\fR?
.fi
.BE
.SH DESCRIPTION
The \fBlink\fR command is available within methods. It takes a series of one
or more method names (\fImethodName ...\fR) and/or pairs of command- and
method-name (\fB{\fIcommandName methodName\fB}\fR) and makes the named methods
available as commands without requiring the explicit use of the name of the
object or the \fBmy\fR command. The method does not need to exist at the time
that the link is made; if the link command is invoked when the method does not
exist, the standard \fBunknown\fR method handling system is used.
.PP
The command name under which the method becomes available defaults to the
method name, except where explicitly specified through an alias/method pair.
Formally, every argument must be a list; if the list has two elements, the
first element is the name of the command to create and the second element is
the name of the method of the current object to which the command links;
otherwise, the name of the command and the name of the method are the same
string (the first element of the list).
.PP
If the name of the command is not a fully-qualified command name, it will be
resolved with respect to the current namespace (i.e., the object namespace).
.SH EXAMPLES
This demonstrates linking a single method in various ways. First it makes a
simple link, then a renamed link, then an external link. Note that the method
itself is unexported, but that it can still be called directly from outside
the class.
.PP
.CS
oo::class create ABC {
    method Foo {} {
        puts "This is Foo in [self]"
    }

        \fBlink\fR Foo
        # The method foo is now directly accessible as foo here
        \fBlink\fR {bar Foo}
        # The method foo is now directly accessible as bar
        \fBlink\fR {::ExternalCall Foo}
        # The method foo is now directly accessible in the global
        # namespace as ExternalCall
    }

    method grill {} {
        puts "Step 1:"
        Foo
        puts "Step 2:"
        bar
    }
}

.SH NAME
my, myclass \- invoke any method of current object or its class
.SH SYNOPSIS
.nf
package require TclOO

\fBmy\fI methodName\fR ?\fIarg ...\fR?
\fBmyclass\fI methodName\fR ?\fIarg ...\fR?
.fi
.BE
.SH DESCRIPTION
.PP
The \fBmy\fR command is used to allow methods of objects to invoke methods
of the object (or its class),
.VS TIP478
and he \fBmyclass\fR command is used to allow methods of objects to invoke
methods of the current class of the object \fIas an object\fR.
.VE TIP478
In particular, the set of valid values for
\fImethodName\fR is the set of all methods supported by an object and its
superclasses, including those that are not exported
.VS TIP500
and private methods of the object or class when used within another method
defined by that object or class.
.VE TIP500
.PP
The object upon which the method is invoked via \fBmy\fR is the one that owns
the namespace that the \fBmy\fR command is contained in initially (\fBNB:\fR the link
remains if the command is renamed), which is the currently invoked object by
default.
.VS TIP478
Similarly, the object on which the method is invoked via \fBmyclass\fR is the
object that is the current class of the object that owns the namespace that
the \fBmyclass\fR command is contained in initially. As with \fBmy\fR, the
link remains even if the command is renamed into another namespace, and
defaults to being the manufacturing class of the current object.
.VE TIP478
.PP
Each object has its own \fBmy\fR and \fBmyclass\fR commands, contained in its
instance namespace.
.SH EXAMPLES
.PP
This example shows basic use of \fBmy\fR to use the \fBvariables\fR method of
the \fBoo::object\fR class, which is not publicly visible by default:
.PP
.CS
oo::class create c {

o count              \fI\(-> prints "1"\fR
o count              \fI\(-> prints "2"\fR
o count              \fI\(-> prints "3"\fR
.CE
.PP
This example shows how you can use \fBmy\fR to make callbacks to private
methods from outside the object (from a \fBtrace\fR), using
\fBnamespace code\fR to enter the correct context. (See the \fBcallback\fR
command for the recommended way of doing this.)
.PP
.CS
oo::class create HasCallback {
    method makeCallback {} {
        return [namespace code {

.SH SYNOPSIS

package require TclOO

\fBoo::singleton\fI method \fR?\fIarg ...\fR?

.nf
\fBoo::object\fR
   \(-> \fBoo::class\fR
       \(-> \fBoo::singleton\fR
.fi
.BE
.SH DESCRIPTION
Singleton classes are classes that only permit at most one instance of
themselves to exist. They unexport the \fBcreate\fR and
\fBcreateWithNamespace\fR methods entirely, and override the \fBnew\fR method
so that it only makes a new instance if there is no existing instance.  It is
not recommended to inherit from a singleton class; singleton-ness is \fInot\fR
inherited. It is not recommended that a singleton class's constructor take any
arguments.
.PP
Instances have their\fB destroy\fR method overridden with a method that always
returns an error in order to discourage destruction of the object, but
destruction remains possible if strictly necessary (e.g., by destroying the
class or using \fBrename\fR to delete it). They also have a (non-exported)
\fB<cloned>\fR method defined on them that similarly always returns errors to
make attempts to use the singleton instance with \fBoo::copy\fR fail.
.SS CONSTRUCTOR
The \fBoo::singleton\fR class does not define an explicit constructor; this
means that it is effectively the same as the constructor of the
\fBoo::class\fR class.
.SS DESTRUCTOR
The \fBoo::singleton\fR class does not define an explicit destructor;
destroying an instance of it is just like destroying an ordinary class (and
will destroy the singleton object).
.SS "EXPORTED METHODS"
.TP
\fIcls \fBnew \fR?\fIarg ...\fR?
.
This returns the current instance of the singleton class, if one exists, and
creates a new instance only if there is no existing instance. The additional
arguments, \fIarg ...\fR, are only used if a new instance is actually
manufactured; that construction is via the \fBoo::class\fR class's \fBnew\fR
method.
.RS
.PP
This is an override of the behaviour of a superclass's method with an
identical call signature to the superclass's implementation.
.RE
.SS "NON-EXPORTED METHODS"
The \fBoo::singleton\fR class explicitly states that \fBcreate\fR and
\fBcreateWithNamespace\fR are unexported; callers should not assume that they
have control over either the name or the namespace name of the singleton instance.
.SH EXAMPLE
.PP
This example demonstrates that there is only one instance even though the
\fBnew\fR method is called three times.
.PP
.CS
\fBoo::singleton\fR create Highlander {
    method say {} {
        puts "there can be only one"
    }

.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
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
point given in \fImntpt\fR using the optional ZIP password \fIpasswd\fR.
Errors during that process are reported in the interpreter \fIinterp\fR.
If \fImountpoint\fR is a NULL pointer, information on all currently mounted
ZIP file systems is written into \fIinterp\fR's result as a sequence of
mount points and ZIP file names.
.PP
\fBTclzipfs_Unmount()\fR undoes the effect of \fBTclzipfs_Mount()\fR,
i.e. it unmounts the mounted ZIP file system at \fImountpoint\fR. Errors are
reported in the interpreter \fIinterp\fR.

.PP
The \fBzipfs\fR package provides tcl with the ability to mount
the contents of a zip file as a virtual file system.
.TP
\fBzipfs exists\fR \fIfilename\fR
.
Return 1 if the given filename exists in the mounted zipfs and 0 if it does not.
.TP
\fBzipfs find\fR \fIdir\fR
.
Recursively lists files including and below the directory \fIdir\fR.
The result list consists of relative path names starting from the
given directory. This command is also used by the \fBzipfs mkzip\fR
and \fBzipfs mkimg\fR commands.
.TP
\fBzipfs info\fR \fIfile\fR
.
Return information about the given file in the mounted zipfs.  The information
consists of (1) the name of the ZIP archive file that contains the file,
(2) the size of the file after decompressions, (3) the compressed size of
the file, and (4) the offset of the compressed data in the ZIP archive file.
.RS
.PP
Note: querying the mount point gives the start of zip data offset in (4),
which can be used to truncate the zip info off an executable.
.RE
.TP
\fBzipfs list\fR \fB?(-glob|-regexp)?\fR \fI?pattern?\fR
.
Return a list of all files in the mounted zipfs.  The order of the names
in the list is arbitrary.
.TP
\fBzipfs mkimg\fR \fIoutfile\fR \fIindir\fR \fI?strip?\fR \fI?password?\fR \fI?infile?\fR
.
Creates an image (potentially a new executable file) similar to
\fBzipfs mkzip\fR. If the \fIinfile\fR parameter is specified,
this file is prepended in front of the ZIP archive, otherwise the file
returned by \fBTcl_NameOfExecutable(3)\fR (i.e. the executable file of
the running process) is used. If the \fIpassword\fR parameter is not empty,
an obfuscated version of that password is placed between the image and ZIP
chunks of the output file and the contents of the ZIP chunk are protected
with that password.
.RS
.PP
Caution: highly experimental, not usable on Android, only partially tested
on Linux and Windows.
.RE
.TP
\fBzipfs mkkey\fR \fIpassword\fR
.
For the clear text \fIpassword\fR argument an obfuscated string version
is returned with the same format used in the \fBzipfs mkimg\fR command.
.TP
\fBzipfs mkzip\fR \fIoutfile\fR \fIindir\fR \fI?strip?\fR \fI?password?\fR
.
Creates a ZIP archive file named \fIoutfile\fR from the contents of the input
directory \fIindir\fR (contained regular files only) with optional ZIP
password \fIpassword\fR. While processing the files below \fIindir\fR the
optional file name prefix given in \fIstrip\fR is stripped off the beginning
of the respective file name.
.RS
.PP
Caution: the choice of the \fIindir\fR parameter
(less the optional stripped prefix) determines the later root name of the
archive's content.
.RE
.TP
\fBzipfs mount ?\fImountpoint\fR? ?\fIzipfile\fR? ?\fIpassword\fR?
.
The \fBzipfs mount\fR command mounts a ZIP archive file as a VFS.
After this command executes, files contained in \fIzipfile\fR
will appear to Tcl to be regular files at the mount point.
.RS
.PP
With no \fIzipfile\fR, returns the zipfile mounted at \fImountpoint\fR.
With no \fImountpoint\fR, return all zipfile/mount pairs.
If \fImountpoint\fR is specified as an empty string, mount on file path.
.RE
.TP
\fBzipfs root\fR
Returns a constant string which indicates the mount point for zipfs volumes
for the current platform. On Windows, this value is zipfs:/. On Unux, //zipfs:/
.RE
.TP
\fBzipfs unmount \fImountpoint\fR
.
Unmounts a previously mounted ZIP archive mounted to \fImountpoint\fR.
