Object-method Reform: - changed interface to object specific commands by requiring an ensemble named "object". The rational behind is essentially to use always the same info command to retrieve object specific methods, no matter whether these are defined on a plain object or an a class object (does not break the "contract" what e.g. "info method" returns).

Now we define methods via:

/cls/ method foo {args} {...body...}

/cls/ object method foo {args} {...body...}

/obj/ object method foo {args} {...body...}

Similarly, aliases, forwards and mixins are defined, e.g.

/cls/ mixin add ...

/cls/ object mixin add ...

/obj/ object mixin add ...

/obj/ require object method ...

The same change propagated as well to the "info" method.

Now we have:

/cls/ info methods ...

/cls/ info object methods ...

/obj/ info object methods ...

Similar, the object parametererization uses

/cls/ create obj -object-mixin M

/cls/ create obj -object-filter f

/metacls/ create cls -mixin M1 -object-mixin M2

/metacls/ create cls -filter f1 -object-filter f2

- as a consequence,

a) "/cls/ class method ...",

"/cls/ class alias ...",

"/cls/ class forward ...",

"/cls/ class filter ...",

"/cls/ class mixin ...",

"/cls/ class info ..."

"/obj/ class method require method ..."

"/obj/ class method require public method ..."

"/obj/ class method require protected method ..."

"/obj/ class method require private method ..."

were dropped

b) "/obj/ method ....",

"/obj/ alias ....",

"/obj/ forward ...."

"/obj/ filter ...."

"/obj/ mixin ...."

"/obj/ info method*"

"/cls/ create obj -mixin M"

"/cls/ create obj -filter f"

"/obj/ method require method ..."

"/obj/ method require public method ..."

"/obj/ method require protected method ..."

"/obj/ method require private method ..."

were dropped

- added package nx::class to allow optionally the "class" notation

"/cls/ class method ..." (and friends, see (a)), and

"/cls/ class info ...

- added package nx::plain-object-method to allow optionally plain method

b) "/obj/ method ...." (and friends, see (b))

- add support to slots to use ensemble methods as setters

nx.tcl: - property has now a boolean non-positional argument "-config" /obj|cls/ property ?-accessor value? ?-config boolean? ?-incremental? ?-class value? spec ?initblock? in symmetry with "-accessor" (parameter option "noconfig" is still needed to flag nsf for variables that should be initialized, which are not configurable - "/obj|cls/ info slot definitions" returns a full command (containing flags and property|variable) - extended regression test

- added functiality for "cget" to call parameter-methods (e.g. "... cget -class"). The method cget calls either "/slot/ get ..." (when slot=... is provided in the parameter spec) or it assumes that the method without argument returns the value - added "::nsf::object::property /obj/ volatile" to query whether a object is volatile or not - "/obj/ cget -volatile" returns now the volatial state of the object - factored out ParameterMethodDispatch() from OConfigureMethod() - extended regression test

Property Reform Part 2: better handling of per-object properties nsf.c: - changed "/class/ __objectconfigure" to "/obj/ __objectconfigure" to be able to handle per-object properties on classes properly. - renamed "info method parametersyntax" -> "info method syntax" - renamed "/obj|cls/ info method parametersyntax" into "/obj|cls/ info method syntax" - replaced "::nsf::methods::class::info::objectparameter" by "::nsf::methods::object::info::objectparameter" - new command "::nsf::parameter::specs ?-configure? ?-noposargs? slotobjs": convert provided slotobjs into a list of parameter specs - new command "::nsf::parameter::get list|name|syntax parameterspec": convert parameter spec into syntax form, or retrieve pieces of information from it (can be extended in the future) - added more or less generic list handling functions TclObjListFreeList(), TclObjListNewElement() and TclObjListAdd() used by "::nsf::parameter::specs" - replaced "::nsf::method::property /obj/ -per-object /name/ slotcontainer ?value?" by "::nsf::object::property /obj/ slotcontainer ?value?" - added "::nsf::object::property /obj/ hasperobjectslots ?value?"

nx.tcl:

- new info methods

* "/obj/ info lookup parameter definitions"

* "/obj/ info lookup parameter names"

* "/obj/ info lookup parameter list"

* "/obj/ info lookup parameter syntax"

- changed "/cls/ info parameter definition ?name?"

into "/cls/ info parameter definitions ?name?"

since ir returns a list. Still, "list" or "syntax" won't

be plural

Property reform part 1:

- disallow protection modifiers for "properties" and

add new flag "-accessor" to "property" and "variable"

This changes definitions like

Class create C {

:property {a a1}

:public property {b b1}

:protected property {c c1}

:private property {d d1}

}

to

Class create C {

:property {a a1}

:property -accessor public {b b1}

:property -accessor protected {c c1}

:property -accessor private {d d1}

}

since "properties" are always public accessible

over the "configure" and "cget" interface, but the

accessors methods might not be public. The value of

the accessor might be also "none" (specifying explicitely

that no accessor is wanted) or "", which means: use the default.

Same holds for "variable"

- disallow parameter option "incremental" and change it to a flag

of the property or variable. The motivation for this is due to

the fact, that "incremental" is a property of the accessor, and

not of the value.

old:

Class create C {

:property foo:int,incremental

:variable bar:int,incremental

}

new:

Class create C {

:property -incremental foo:int

:variable -incremental bar:int

}

- disallow "public class property" and friends since these are not needed

- removed parameter property "noaccessor"

- removed "nx::configure defaultPropertyCallProtection" and

method hook "__default_property_call_protection"

- introduced "nx::configure defaultAccessor" and

method hook "__default_accessor"

- for the time being, "defaultAccessor" is "public" for NX and XOTcl,

will be changed to "none" in NX

- extended regression test (new file properties.test)

Interim commit

Reintroduce forValueCheck

- use "nsf::relation $cl superclass" instead of "$cl configure -superclass"

nx.tcl: - set multiplicty for mixins and filters by default from 1..n to 0..n to avoid error messages, when e.g. empty mixin lists are configured. Setting emtpy mixin-lists is strictly speaking not necessary, but this eases the code in cases the lists are sometimes empty.

Adding a test case and a preliminary fix for the parameter option interactions

- library/nx/nx.tcl: Following the code review, implemented a first scheme for handling traces in setCheckedInstVar. This gives us consistent behavior for defaults and traces (valuechangedcmd) across classes and objects. - tests/parameters.test: Adjusted the relevant tests - Pending: setCheckedInstVar currently uses ::nsf::is to validate the value (e.g., default value) to be set. However, it might get passed parameter options which do not fit the NSF_DISALLOWED_ARG_VALUECHECKED filter.

Merge branch 'master' of ssh://alice.wu-wien.ac.at/usr/local/src/git-repo/nsf

- honor default type in "info slot names"

- Addressed a number of issues in the NX slot infrastructure (which revealed themselves when running Mark's BusinessActivities implementation in XOTcl2 mode): - generic/nsf.c: Initcmd blocks (as set for registering per-class slot traces) were subjected to argument checks causing unexpected behavior (e.g., attempts of unboxing initcmds as Tcl lists or of checking initcmds against value types). This was fixed by exempting NSF_ARG_INITCMD params from argument checking in ArgumentCheck() explicitly. - library/nx/nx.tcl: For per-class parameters, the use of valuechangedcmd effectively overruled the default value specified (simply because the generated initcmd holding the trace statements took the place of the default value). While for defaultcmd and for valuecmd the parallel use of default is forbidden, the valuechangedcmd semantics allow for specifying a default, in principle. This was fixed by providing a default-setting statement in the initcmd. - tests/parameters.test: Added tests to cover the above (and beyond). - library/xotcl/library/xotcl2.tcl: Extended the backwards compatibility of the hybrid XOTcl2/NX slots infrastructure to the XOTcl 1 interface: This includes support for inline -proc statements and instvar. This compat level corresponds to the slot interface as documented (by examples) in the XOTcl language ref and the manual. - library/xotcl/tests/slottest.xotcl: Added tests for the above compat enhancements.
