- changed name "/obj|cls/ slot info definition" to "/obj|cls/ slot info definition" since result is a set - dropped parameter method "properties" - dropped "/obj/ info properties" (since "properties" or "variables" are returned")

  1. … 8 more files in changeset.
- 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)

nsf.c: - made argument of cget required

nx.tcl:

- added Tk-style methods "configure" and "cget"

- added additional regression test set for cget and configure

  1. … 7 more files in changeset.
- rename nx::Object.configure to nx::Object.__configure to free method name "configure" for an e.g. tk-like configure

  1. … 5 more files in changeset.
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.

  1. … 3 more files in changeset.
- Replaced errorneous check using the object-specific rather than the class-specific options in the query mode of ::nsf::relation with class-filter. This prevented [::nsf::relation /cls/ class-filter] from returning any filter info. As a consequence, the incremental interface of the filter slot failed (e.g., [/cls/ filter add aFilterProc] effectively reset the class-filter cmd list instead of adding to it). Thx are due to Markus Moldaschl for reporting the issue. - Aligning class-filter and object-filter behaviour on errors during filter additions to the state-preserving behaviour of object-mixin and class-mixin. - Adding basic tests on object-filter/class-filter (::nsf::relation, filter slot interface) and specific ones to cover the above issues.

- fixed potential crash from method caching, when permissions on cmds are changed and become e.g. unresolvable - removed flag allowmethoddispatch, since behavior can be achived via private flag. - extended regression test

  1. … 9 more files in changeset.
- deacitivate for the time being allowmethoddispatch (make it behave always like true) - added instead new flag "perobjectdispatch" to make behavior of ensembleobjects configurable. - The behavior for keepcallerself is currently only activated for the method-interface for object dispatch, since otherwise the following would be dangerous, since "o2 foo" would destroy o2 nx::Object create o1 nsf::object::property o1 keepcallerself true nx::Object create o2 { ::public method foo {} {o1 destroy} } o2 foo

- nsf.c: start all error messages with a lower case word for consistency and to follow closer to Tcl's conventions

- use alias-stubs for aliases pointing to objects. This allows us to distinguish between cases, where an object is dispatchable due to the alias or due to allowmethoddispatch (when the object happens to be a subobject and has therefore its cmd in the same namespace). The semantics are now: - aliases to objects are always dispatchable, no matter, how allowmethoddispatch is set. - direct subobjects of objects are currently on dispatchable when allowmethoddispatch is set.

- alias reform: instead of calling first an alias with a stack frame followed by the dispatched of the aliased cmd, resolve aliases internally in dispatch. This has the advantage that we do not have to ignore the "transparent" stack frame in some sitations, and we have much less problems with the names of the aliased cmds (e.g. objects) in the introspection methods. Additionally, several problem cases disappeared from the regression test cases. In addition, the new approach is faster. - eliminating obsolete flag NSF_CSC_CALL_IS_TRANSPARENT

  1. … 9 more files in changeset.
- Added exerpimental object property "allowmethoddispatch" for child-objects to be called from parent objects via method interface. Background: both, per-object methods and childobjects are implemented via cmds in the same tcl namespace. Without special care, both are callable via the standard dispatch. Apparently, this is not always wanted. - handled allowmethoddispatch and keepcallerself in copy/move - set allowmethoddispatch per-default in XOTcl - removed visablilty of objects with "allowmethoddispatch" false in "info methods" and "info search methods" - extended regression test

  1. … 10 more files in changeset.
- generic/nsf.c: Have NsfNSCopyCmdsCmd() handle "returns" method properties for scripted methods. Note that aliases and forwards are not yet covered by the copying procedure as implemented by NsfNSCopyCmdsCmd(). - tests/info-method.test: Added tests for "info method returns" and "info method defintion" covering "returns" method properties.

  1. … 1 more file in changeset.
nsf.c: - added method NsfMethodNamePath() to compute the ensemble path in error messages - reduce verbosity - extended regression test

  1. … 4 more files in changeset.
- rename "info method handle /methodName/" into "info method registrationhandle /methodName/" - rename "info method origin /methodName/" into "info method definitionhandle /methodName/" - added "info method origin" to return the target of an alias (or empty)

  1. … 19 more files in changeset.
