nx.tcl: - add "set" as a method name for relation slots - implemented relation slot "mixin" and "object-mixin" via "slotassign" to disallow "/obj/ mixin /value/" and "/obj/ object mixin /value/" to use instead "/obj/ mixin set /value/" and "/obj/ object mixin set /value/" while keeping "configure" and "cget" working. This has the advantage that "/obj/ mixin set" does not try to replace the mixin chain by "set" - adapted regression test - TODO: check, if we need the explicit "slotassign"? isn't the presence of the slotObj sufficient? maybe "-forwardToSlot" in relationSlots? - TODO: demangle "slotassign" in "ObjectParameterSlot protected method getParameterOptions" and check interactions - TODO: to the same as -mixin and -object-mixin to -filter and -object-filter - TODO: clean up relation slot mixin variants - TODO: do we really like the fact that we have to write now "B mixin set M2" instead of "B mixin M2"? - TODO: should we disallow "B mixin" and enforce instead of "B mixin get" ? - TODO: we could as well allow "B mixin clear" instead of "B mixin set {}" - TODO: allow "set" for variable slots as well. Do we need "assign"?

nsf.c: - change name of enumeratorConverterEntry to Nsf_EnumeratorConverterEntry, move it with NSF_ARG_* flags to tcl.h to make it available in derived modules using the converter - Added editor hints for a more uniform appearance

nx::test: - change test cases to newer interface - don't use "namespace import nx::*" in test cases when not required

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

- pass property name to slot "initialize" method to conform with the interface to "assign", "get" ... (all these receive the property name as well) - allow slot "initialize" method to be protected (handled similarly to "init")

- Fixed a bad interaction between Tcl's apply (pushing lambda frames) and the variable resolvers. The variable resolver was not able to resolve variables, while the command resolver was still working correctly. - Extended regression test

- nx.tcl * renamed "attribute" to "property" * renamed "defaultAttributeCallProtection" to "defaultPropertyCallProtection" * renamed "nx::Attribute" to ""nx::VariableSlot" * renamed "BootStrapAttributeSlot" to "BootStrapVariableSlot" * renamed "createBootstrapAttributeSlots" to "createBootstrapVariableSlots" * removed method attributes * implemented old attributes definition in xotcl2 as method "parameter"

- test.tcl: * don't export Test per-default * define Test as nx::Test * make Test parameter count 1 the default, change to higher numbers where needed

- nsf: renamed nsf::isobject to nsf::object::exists - nsf: renamed nsf::qualify to nsf::object::qualify

* Hopefully the last big naming change: Instead of writing "C class-object method foo {} {...}" one can write now "C class method foo {} {...}" to define a class method named "foo" for class "C". This naming change became possible by defining XOTcl's "class" (and "superclass") as object parameter only. To change a class of an object o, one has to use "o configure -class NEWCLASS". The term "object-class" looks alien to language beginners, the term "class" is much more straightforward. Changing classes or superclasses is seldomly used by typicall application programs.

For already existing nx scripts, changing "object-class" into

class should be straightforward.

* various documentation updates (migration guide, nx tutorial)

- changed names of var handling commands in nsf: ::nsf::existsvar => ::nsf::var::exists ::nsf::importvar => ::nsf::var::import ::nsf::setvar => ::nsf::var::set

- changed named of method handling commands in nsf: ::nsf::methodproperty => ::nsf::method::property ::nsf::method => ::nsf::method::create ::nsf::methoddelete => ::nsf::method::delete ::nsf::alias => ::nsf::method::alias ::nsf::forward => ::nsf::method::forward ::nsf::setter => ::nsf::method::setter (updated regression test, docs, ...)

  1. … 24 more files in changeset.
- removed c-implementation of method vwait, it was replaced by "vwait :varName". We had to allow flag TCL_GLOBAL_ONLY in InterpColonVarResolver(), since Tcl vwait implementation calls it with that flag. - added a scripted implementation for vwait in xotcl2
