Fellows <[email protected]> IMPLEMENTATION OF TIP#380. * doc/define.n, doc/object.n, generic/tclOO.c, generic/tclOOBasic.c: * generic/tclOOCall.c, generic/tclOODefineCmds.c, generic/tclOOInt.h: * tests/oo.test: Switch definitions of lists of things in objects and classes to a slot-based approach, which gives a lot more flexibility and programmability at the script-level. Introduce new [::oo::Slot] class which is the implementation of these things. ***POTENTIAL INCOMPATIBILITY*** The unknown method handler now may be asked to deal with the case where no method name is provided at all. The default implementation generates a compatible error message, and any override that forces the presence of a first argument (i.e., a method name) will continue to function as at present as well, so this is a pretty small change. * generic/tclOOBasic.c (TclOO_Object_Destroy): Made it easier to do a tailcall inside a normally-invoked destructor; prevented leakage out to calling command. 2012-03-25 Jan Nijtmans <[email protected]> * generic/tclInt.decls: [Bug 3508771]: load tclreg.dll in cygwin * generic/tclIntPlatDecls.h: tclsh. Implement TclWinConvertError, * generic/tclStubInit.c: TclWinConvertWSAError, and various more * unix/Makefile.in: win32-specific internal functions for * unix/tcl.m4: Cygwin, so win32 extensions using those * unix/configure: can be loaded in the cygwin version of * win/tclWinError.c: tclsh. 2012-03-23 Jan Nijtmans <[email protected]> * generic/tclInt.decls: Revert some cygwin-related signature * generic/tclIntPlatDecls.h: changes from [835f8e1e9d] (2010-01-22). * win/tclWinError.c: They were an attempt to make the cygwin port compile again, but since cygwin is based on unix this serves no purpose any more. * win/tclWinSerial.c: Use EAGAIN in stead of EWOULDBLOCK, * win/tclWinSock.c: because in VS10+ the value of EWOULDBLOCK is no longer the same as EAGAIN. * unix/Makefile.in: Add tclWinError.c to the CYGWIN build. * unix/tcl.m4: * unix/configure: 2012-03-20 Jan Nijtmans <[email protected]> * generic/tcl.decls: [Bug 3508771]: load tclreg.dll in cygwin * generic/tclInt.decls: tclsh. Implement TclWinGetPlatformId, * generic/tclIntPlatDecls.h: Tcl_WinUtfToTChar, Tcl_WinTCharToUtf (and * generic/tclPlatDecls.h: a dummy TclWinCPUID) for Cygwin, so win32 * generic/tclStubInit.c: extensions using those can be loaded in * unix/tclUnixCompat.c: the cygwin version of tclsh. 2012-03-19 Venkat Iyer <[email protected]> * library/tzdata/America/Atikokan: Update to tzdata2012b. * library/tzdata/America/Blanc-Sablon * library/tzdata/America/Dawson_Creek * library/tzdata/America/Edmonton |

Each \fImethodName\fR names a single filtering method (which may be exposed or not exposed); it is not an error for a non-existent method to be named. Note that the actual list of filters also depends on the filters set upon any classes that the object is an instance of. .VS By default, this slot works by appending. .VE .TP \fBforward\fI name cmdName \fR?\fIarg ...\fR? . This creates or updates a forwarded object method called \fIname\fR. The method is defined be forwarded to the command called \fIcmdName\fR, with additional arguments, \fIarg\fR etc., added before those arguments specified by the caller of the method. Forwarded methods should be deleted using the \fBmethod\fR subcommand. The method will be exported if \fIname\fR starts with a lower-case letter, and non-exported otherwise. .TP \fBmethod\fI name argList bodyScript\fR . This creates, updates or deletes an object method. The name of the method is \fIname\fR, the formal arguments to the method (defined using the same format as for the Tcl \fBproc\fR command) will be \fIargList\fR, and the body of the method will be \fIbodyScript\fR. When the body of the method is evaluated, the current namespace of the method will be a namespace that is unique to the object. The method will be exported if \fIname\fR starts with a lower-case letter, and non-exported otherwise. .TP \fBmixin\fR ?\fI\-slotOperation\fR? ?\fIclassName ...\fR? .VS This slot (see \fBSLOTTED DEFINITIONS\fR below) .VE sets or updates a per-object list of additional classes that are to be mixed into the object. Each argument, \fIclassName\fR, names a single class that is to be mixed in. .VS By default, this slot works by replacement. .VE .TP \fBrenamemethod\fI fromName toName\fR . This renames the method called \fIfromName\fR in an object to \fItoName\fR. The method must have previously existed in the object, and \fItoName\fR must not previously refer to a method in that object. Does not affect the classes that the object is an instance of. Does not change the export status of the method; if it was exported before, it will be afterwards. .TP \fBunexport\fI name \fR?\fIname ...\fR? . This arranges for each of the named methods, \fIname\fR, to be not exported (i.e. not usable outside the object through the object's command, but instead just through the \fBmy\fR command visible in the object's context) by the object being defined. Note that the methods themselves may be actually defined by a class; instance unexports override class visibility. .TP \fBvariable\fR ?\fI\-slotOperation\fR? ?\fIname ...\fR? .VS This slot (see \fBSLOTTED DEFINITIONS\fR below) arranges for each of the named variables to be automatically made available in the methods declared by the object being defined. Each variable name must not have any namespace separators and must not look like an array access. All variables will be actually present in the object on which the method is executed. Note that the variable lists declared by the classes and mixins of which the object is an instance are completely disjoint; the list of variable names is just for methods declared by this object. By default, this slot works by appending. .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: .VE .TP \fIslot\fR \fB\-append\fR ?\fImember ...\fR? .VS This appends the given \fImember\fR elements to the slot definition. .VE .TP \fIslot\fR \fB\-clear\fR .VS This sets the slot definition to the empty list. .VE .TP \fIslot\fR \fB\-set\fR ?\fImember ...\fR? .VS 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 operations should be used explicitly in those circumstances. .SS "SLOT IMPLEMENTATION" Internally, slot objects also define a method \fB\-\-default\-operation\fR which is forwarded to the default operation of the slot (thus, for the class .QW \fBvariable\fR slot, this is forwarded to .QW "\fBmy \-append\fR" ), and these methods which provide the implementation interface: .VE .TP \fIslot\fR \fBGet\fR .VS 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. .VE .TP \fIslot\fR \fBSet \fIelementList\fR .VS 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. .VE .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. .PP .CS |
