Tcl Source Code

2011-05-25  Don Porter  <[email protected]>

	* library/msgcat/msgcat.tcl:	Bump to msgcat 1.4.4.
	* library/msgcat/pkgIndex.tcl:
	* unix/Makefile.in
	* win/Makefile.in

2011-05-25  Donal K. Fellows  <[email protected]>

	* generic/tclOO.h (TCLOO_VERSION): Bump version.

	IMPLEMENTATION OF TIP#381.

	* doc/next.n, doc/ooInfo.n, doc/self.n, generic/tclOO.c,
	* generic/tclOOBasic.c, generic/tclOOCall.c, generic/tclOOInfo.c,
	* generic/tclOOInt.h, tests/oo.test, tests/ooNext2.test: Added
	introspection of call chains ([self call], [info object call], [info
	class call]) and ability to skip ahead in chain ([nextto]).

2011-05-24  Venkat Iyer <[email protected]>

	* library/tzdata/Africa/Cairo: Update to Olson tzdata2011g

2011-05-24  Donal K. Fellows  <[email protected]>

	* library/msgcat/msgcat.tcl (msgcat::mcset, msgcat::mcmset): Remove
	some useless code; [dict set] builds dictionary levels for us.

2011-05-17  Andreas Kupries  <[email protected]>

	* generic/tclCompile.c (TclFixupForwardJump): Tracked down and fixed
	* generic/tclBasic.c (TclArgumentBCEnter): the cause of a violation
	of my assertion that 'ePtr->nline == objc' in TclArgumentBCEnter.
	When a bytecode was grown during jump fixup the pc -> command line
	mapping was not updated. When things aligned just wrong the mapping
	would direct command A to the data for command B, with a different
	number of arguments.

2011-05-11  Reinhard Max  <[email protected]>

	* unix/tclUnixSock.c (TcpWatchProc): No need to check for server
	sockets here, as the generic server code already takes care of
	that.
	* tests/socket.test (accept): Add tests to make sure that this
	remains so.

2011-05-10  Don Porter  <[email protected]>

	* generic/tclInt.h:     New internal routines TclScanElement() and
	* generic/tclUtil.c:    TclConvertElement() are rewritten guts of
	machinery to produce string rep of lists.  The new routines avoid
	and correct [Bug 3173086].  See comments for much more detail.

The introspection capabilities can be used to discover what class implements a
method and get how it is defined. This procedure illustrates how:
.PP
.CS
proc getDef {obj method} {
    foreach inf [\fBinfo object call\fR $obj $method] {
        lassign $inf calltype name locus methodtype
        # Assume no forwards or filters, and hence no $calltype
        # or $methodtype checks...
        if {$locus eq "object"} {
            return [\fBinfo object definition\fR $obj $name]
        } else {
            return [\fBinfo class definition\fR $locus $name]
        }
    }
    error "no definition for $method"
}
.CE
.PP
This is an alternate way of implementing the definition lookup is by manually
scanning the list of methods up the inheritance tree. This code assumes that
only single inheritance is in use, and that there is no complex use of
mixed-in classes:
.PP
.CS
proc getDef {obj method} {
    if {$method in [\fBinfo object methods\fR $obj]} {
        # Assume no forwards
        return [\fBinfo object definition\fR $obj $method]

.SH SYNOPSIS
.nf
package require TclOO

\fBnext\fR ?\fIarg ...\fR?
\fBnextto\fI class\fR ?\fIarg ...\fR?
.fi
.BE

.SH DESCRIPTION
.PP
The \fBnext\fR command is used to call implementations of a method by a class,
superclass or mixin that are overridden by the current method. It can only be
used from within a method. It is also used within filters to indicate the
point where a filter calls the actual implementation (the filter may decide to
not go along the chain, and may process the results of going along the chain
of methods as it chooses). The result of the \fBnext\fR command is the result
of the next method in the method chain; if there are no further methods in the
method chain, the result of \fBnext\fR will be an error. The arguments,
\fIarg\fR, to \fBnext\fR are the arguments to pass to the next method in the
chain.
.PP
The \fBnextto\fR command is the same as the \fBnext\fR command, except that it
takes an additional \fIclass\fR argument that identifies a class whose
implementation of the current method chain (see \fBinfo object call\fR) should
be used; the method implementation selected will be the one provided by the
given class, and it must refer to an existing non-filter invocation that lies
further along the chain than the current implementation.
.SH "THE METHOD CHAIN"
.PP
When a method of an object is invoked, things happen in several stages:
.IP [1]
The structure of the object, its class, superclasses, filters, and mixins, are
examined to build a \fImethod chain\fR, which contains a list of method
implementations to invoke.

The \fBself\fR command, 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 allow the method to discover information about how it was called. It
takes an argument, \fIsubcommand\fR, that tells it what sort of information is
actually desired; if omitted the result will be the same as if \fBself
object\fR was invoked. The supported subcommands are:
.TP
\fBself call\fR
.
This returns a two-element list describing the method implementations used to
implement the current call chain. The first element is the same as would be
reported by \fBinfo object call\fR for the current method (except that this
also reports useful values from within constructors and destructors, whose
names are reported as \fB<constructor>\fR and \fB<destructor>\fR
respectively), and the second element is an index into the first element's
list that indicates which actual implementation is currently executing (the
first implementation to execute is always at index 0).
.TP
\fBself caller\fR
.
When the method was invoked from inside another object method, this subcommand
returns a three element list describing the containing object and method. The
first element describes the declaring object or class of the method, the
second element is the name of the object on which the containing method was
invoked, and the third element is the name of the method (with the strings

b foo                \fI\(-> prints "this is the ::b object"\fR
.CE
.PP
This demonstrates what a method call chain looks like, and how traversing
along it changes the index into it:

    method x {} {
        puts "Cls: [\fBself call\fR]"
    }

        puts "Obj: [\fBself call\fR]"
        next
        puts "Obj: [\fBself call\fR]"
    }
}
