	* doc/next.n (METHOD SEARCH ORDER): Bug [3606943]: Corrected
	description of method search order.

2013-09-18  Donal Fellows  <[email protected]>

	Bump TclOO version to 1.0.1 for release.

2013-09-17  Donal Fellows  <[email protected]>

	* generic/tclBinary.c (BinaryEncodeUu, BinaryDecodeUu): [Bug 2152292]:
	Corrected implementation of the core of uuencode handling so that the
	line length processing is correctly applied.
	***POTENTIAL INCOMPATIBILITY***
	Existing code that was using the old versions and working around the
	limitations will now need to do far less. The -maxlen option now has
	strict limits on the range of supported lengths; this is a limitation
	of the format itself.

2013-09-09  Donal Fellows  <[email protected]>

	* generic/tclOOMethod.c (CloneProcedureMethod): [Bug 3609693]: Strip
	the internal representation of method bodies during cloning in order
	to ensure that any bound references to instance variables are removed.

2013-09-01  Donal Fellows  <[email protected]>

	* generic/tclBinary.c (BinaryDecodeHex): [Bug b98fa55285]: Ensure that
	whitespace at the end of a string don't cause the decoder to drop the
	last decoded byte.

2013-08-03  Donal Fellows  <[email protected]>

	call an external command.

2013-05-06  Jan Nijtmans  <[email protected]>

	* generic/tclStubInit.c: Add support for Cygwin64, which has a 64-bit
	* generic/tclDecls.h: "long" type. Binary compatibility with win64
	requires that all stub entries use 32-bit long's, therefore the need
	for various wrapper functions/macros. For Tcl 9 a better solution is
	needed, but that cannot be done without introducing binary
	incompatibility.

	* library/platform/platform.tcl (::platform::LibcVersion):
	* library/platform/pkgIndex.tcl: Followup to the 2013-01-30 change.
	The RE become too restrictive again. SuSe added a timestamp after the
	version. Loosened up a bit. Bumped package to version 1.0.12.

2013-04-29  Donal K. Fellows  <[email protected]>

	* generic/tclCompCmds.c (TclCompileArraySetCmd): Generate better code
	when the list of things to set is a literal.

2013-04-25  Jan Nijtmans  <[email protected]>

	* generic/tclDecls.h: Implement Tcl_NewBooleanObj, Tcl_DbNewBooleanObj
	and Tcl_SetBooleanObj as macros using Tcl_NewIntObj, Tcl_DbNewLongObj
	and Tcl_SetIntObj. Starting with Tcl 8.5, this is exactly the same, it
	only eliminates code duplication.
	* generic/tclInt.h: Eliminate use of NO_WIDE_TYPE everywhere: It's
	exactly the same as TCL_WIDE_INT_IS_LONG

2013-04-19  Jan Nijtmans  <[email protected]>

	Tcl_GetIndexFromObj as (faster/stack-saving) macros around resp their

the stack trace text they append to the \fB\-errorinfo\fR option.
Tcl provides several simpler interfaces to more directly set
these return options.
.PP
The \fB\-errorinfo\fR option holds a stack trace of the
operations that were in progress when an error occurred,
and is intended to be human-readable.
The \fB\-errorcode\fR option holds a Tcl list of items that
are intended to be machine-readable.
The first item in the \fB\-errorcode\fR value identifies the class of
error that occurred
(e.g., POSIX means an error occurred in a POSIX system call)
and additional elements hold additional pieces
of information that depend on the class.
See the manual entry on the \fBerrorCode\fR variable for details on the
various formats for the \fB\-errorcode\fR option used by Tcl's built-in
commands.
.PP
The \fB\-errorinfo\fR option value is gradually built up as an
error unwinds through the nested operations.
Each time an error code is returned to \fBTcl_Eval\fR, or
any of the routines that performs script evaluation,
the procedure \fBTcl_AddErrorInfo\fR is called to add
additional text to the \fB\-errorinfo\fR value describing the

occurred after all.
The global variables \fBerrorInfo\fR and
\fBerrorCode\fR are not modified by \fBTcl_ResetResult\fR
so they continue to hold a record of information about the
most recent error seen in an interpreter.

a token for it. The token is required in calls to most other Tcl
procedures, such as \fBTcl_CreateCommand\fR, \fBTcl_Eval\fR, and
\fBTcl_DeleteInterp\fR.  The token returned by \fBTcl_CreateInterp\fR
may only be passed to Tcl routines called from the same thread as
the original \fBTcl_CreateInterp\fR call.  It is not safe for multiple
threads to pass the same token to Tcl's routines.
The new interpreter is initialized with the built-in Tcl commands
and with standard variables like \fBtcl_platform\fR and \fBenv\fR. To
bind in additional commands, call \fBTcl_CreateCommand\fR, and to
create additional variables, call \fBTcl_SetVar\fR.
.PP
\fBTcl_DeleteInterp\fR marks an interpreter as deleted; the interpreter
will eventually be deleted when all calls to \fBTcl_Preserve\fR for it have
been matched by calls to \fBTcl_Release\fR. At that time, all of the
resources associated with it, including variables, procedures, and
application-specific command bindings, will be deleted. After
\fBTcl_DeleteInterp\fR returns any attempt to use \fBTcl_Eval\fR on the

.SH EXAMPLE
.PP
The usual pattern for Tcl commands that invoke other Tcl commands
is something like:
.PP
.CS
int
\fITheCmdOldObjProc\fR(
    ClientData clientData,
    Tcl_Interp *interp,
    int objc,
    Tcl_Obj *const objv[])

        \fITheCmdOldObjProc\fR, clientData, TheCmdDeleteProc);

.PP
To enable a command like this one for trampoline-based evaluation,
it must be split into three pieces:
.IP \(bu
A non-trampoline implementation, \fITheCmdNewObjProc\fR,
which will simply create a trampoline

int
\fITheCmdNewObjProc\fR(
    ClientData clientData,

            clientData, objc, objv);
}

.PP
The trampoline-enabled implementation requests postprocessing,
and returns to the trampoline requesting command evaluation.
.PP
.CS

\fBTcl_NRCreateCommand\fR is used in place of
\fBTcl_CreateObjCommand\fR.  It accepts two command procedures instead
of one. The first is for use when no trampoline is yet on the stack,
and the second is for use when there is already a trampoline in place.

\fBbinary scan\fR, does the opposite: it extracts data
from a binary string and returns it as ordinary Tcl string values.
.VS 8.6
The \fBbinary encode\fR and \fBbinary decode\fR subcommands convert
binary data to or from string encodings such as base64 (used in MIME
messages for example).
.VE 8.6
.PP
Note that other operations on binary data, such as taking a subsequence of it,
getting its length, or reinterpreting it as a string in some encoding, are
done by other Tcl commands (respectively \fBstring range\fR,
\fBstring length\fR and \fBencoding convertfrom\fR in the example cases).  A
binary string in Tcl is merely one where all the characters it contains are in
the range \eu0000\-\eu00FF.
.SH "BINARY ENCODE AND DECODE"
.VS 8.6
.PP
When encoding binary data as a readable string, the starting binary data is
passed to the \fBbinary encode\fR command, together with the name of the
encoding to use and any encoding-specific options desired. Data which has been
encoded can be converted back to binary form using \fBbinary decode\fR. The

\fBuuencode\fR
.
The \fBuuencode\fR binary encoding used to be common for transfer of data
between Unix systems and on USENET, but is less common these days, having been
largely superseded by the \fBbase64\fR binary encoding.
.RS
.PP
During encoding, the following options are supported (though changing them may
produce files that other implementations of decoders cannot process):
.TP
\fB\-maxlen \fIlength\fR
.
Indicates that the output should be split into lines of no more than
\fIlength\fR characters. By default, lines are split every 61 characters, and
this must be in the range 3 to 85 due to limitations in the encoding.
.TP
\fB\-wrapchar \fIcharacter\fR
.
Indicates that, when lines are split because of the \fB\-maxlen\fR option,
\fIcharacter\fR should be used to separate lines. By default, this is a
newline character,
.QW \en .
.PP
During decoding, the following options are supported:
.TP
\fB\-strict\fR
.
Instructs the decoder to throw an error if it encounters unexpected whitespace
characters. Otherwise it ignores them.
.PP
Note that neither the encoder nor the decoder handle the header and footer of
the uuencode format.
.RE
.VE 8.6
.SH "BINARY FORMAT"
.PP
The \fBbinary format\fR command generates a binary string whose layout
is specified by the \fIformatString\fR and whose contents come from
the additional arguments.  The resulting binary value is returned.

universal.  To transfer floating-point numbers portably between all
architectures, use their textual representation (as produced by
\fBformat\fR) instead.
.SH EXAMPLES
.PP
This is a procedure to write a Tcl string to a binary-encoded channel as
UTF-8 data preceded by a length word:
.PP
.CS
proc \fIwriteString\fR {channel string} {
    set data [encoding convertto utf-8 $string]
    puts -nonewline [\fBbinary format\fR Ia* \e
            [string length $data] $data]
}
.CE
.PP
This procedure reads a string from a channel that was written by the
previously presented \fIwriteString\fR procedure:
.PP
.CS
proc \fIreadString\fR {channel} {
    if {![\fBbinary scan\fR [read $channel 4] I length]} {
        error "missing length"
    }
    set data [read $channel $length]
    return [encoding convertfrom utf-8 $data]
}
.CE
.PP
This converts the contents of a file (named in the variable \fIfilename\fR) to
base64 and prints them:
.PP
.CS
set f [open $filename rb]
set data [read $f]
close $f
puts [\fBbinary encode\fR base64 \-maxlen 64 $data]

files when using the default \fBpackage unknown\fR handler).
This variable is initialized during startup to contain, in order:
the directories listed in the \fBTCLLIBPATH\fR environment variable,
the directory named by the \fBtcl_library\fR global variable,
the parent directory of \fBtcl_library\fR,
the directories listed in the \fBtcl_pkgPath\fR variable.
Additional locations to look for files and package indices should
normally be added to this variable using \fBlappend\fR.

\fBenv(TCL_LIBRARY)\fR
If set, then it specifies the location of the directory containing
library scripts (the value of this variable will be
assigned to the \fBtcl_library\fR variable and therefore returned by
the command \fBinfo library\fR).  If this variable is not set then
a default value is used.

This variable contains a regular expression that is used by routines
like \fBtcl_endOfWord\fR to identify whether a character is part of a
word or not.  If the pattern matches a character, the character is
considered to be a word character.  On Windows platforms, words are
comprised of any character that is not a space, tab, or newline.  Under
Unix, words are comprised of numbers, letters or underscores.

The method chain is cached for future use.
.SS "METHOD SEARCH ORDER"
.PP
When constructing the method chain, method implementations are searched for in
the following order:
.IP [1]


In the classes mixed into the object, in class traversal order. The list of
mixins is checked in natural order.
.IP [2]
In the classes mixed into the classes of the object, with sources of mixing in
being searched in class traversal order. Within each class, the list of mixins
is processed in natural order.
.IP [3]
In the object itself.
.IP [4]
In the object's class.
.IP [5]
In the superclasses of the class, following each superclass in a depth-first
fashion in the natural order of the superclass list.
.PP
Any particular method implementation always comes as \fIlate\fR in the
resulting list of implementations as possible; this means that if some class,
A, is both mixed into a class, B, and is also a superclass of B, the instances
of B will always treat A as a superclass from the perspective of inheritance.
This is true even when the multiple inheritance is processed indirectly.
.SS FILTERS
.PP
When an object has a list of filter names set upon it, or is an instance of a
class (or has mixed in a class) that has a list of filter names set upon it,
before every invocation of any method the filters are processed. Filter
implementations are found in class traversal order, as are the lists of filter
names (each of which is traversed in natural list order). Explicitly invoking

You should note that it is also common practice to install tclsh with
its version number as part of the name.  This has the advantage of
allowing multiple versions of Tcl to exist on the same system at once,
but also the disadvantage of making it harder to write scripts that
start up uniformly across different versions of Tcl.
.SH "VARIABLES"

When \fBtclsh\fR is invoked interactively it normally prompts for each
command with
.QW "\fB% \fR" .
You can change the prompt by setting the global
variables \fBtcl_prompt1\fR and \fBtcl_prompt2\fR.  If variable
\fBtcl_prompt1\fR exists then it must consist of a Tcl script
to output a prompt;  instead of outputting a prompt \fBtclsh\fR
will evaluate the script in \fBtcl_prompt1\fR.
The variable \fBtcl_prompt2\fR is used in a similar way when
a newline is typed but the current command is not yet complete;
if \fBtcl_prompt2\fR is not set then no prompt is output for
incomplete commands.
