nsf.c - removed obsolete function AssertionAppendPrePost() - removed obsolete function NsfNSCopyCmdsCmd() and ::nsf::nscopycmd (handled now more general on scripting level in the "copy" method)

nx.tcl:

- "copy" method: fixed copying of class-level per-object methods

- extended regression tests

nsf.c - fixed a bug in "info methods returns" in cases, where no returns info was available. - we can "/obj/ copy" now objects/classes containing * aliases * setter * ensemble methods * method protections Instead of handling cmd copying in NsfNSCopyCmdsCmd, it is replaced now by introspection. - extended regression test

- changed multiplicity of mixin, object-mixin, filter, object-filter from 1..n to 0..n; rationale: when one has a list of eg. mixins, which should be passed, one has to test for the length before passing it, otherwise the empty list would generate an error. Allowing 0..n makes the usage simpler and the program shorter.

nx.tcl: - replaced functionality of "/obj/ configure" by "/obj/ info configure" to re-enable semantics of the plain configure method, even when called without arguments. "/obj/ info configure" is actually a convenience method to allow to write o1 info configure instead of o1 info lookup configure syntax

- renamed initblock parameter from __initcmd to __initblock - renamed nsf::configure parameter from "keepinitcmds" to "keepcmds" - saving "keepcmds" in an associative array named "__cmd(/parameternName)" to allow saving of multiple parmeters with less nameclash danger (when application stays away from variables stating with double underscore)

- removed some TODOs from tests/parameters.test

- parameter dispositions:

We differentiate now between "initcmd" and "cmd": an "initcmd" is only

evaluated once, but one can provide configure values for this parameter

later. a "cmd" is executed on every evaluation, it is only possible

to pass cmds to it. The trailing argument of the configure parameters

(used e.g. for scripted object/class definitions) is now of type "cmd".

Implementation not yet complete (object cases are not correct).

- C-code Generator: added "-typeName" for enumeration types that allows for disambiguation of enumerations with different argument names. Before that, the argument name determined the c-type of the enumeration. Therefore it was not possible to use argName "-type" for two different functions with a different list of enumerators.

- changed "-methodtype" to simply "-type" in

/obj/ info methods ... ?-type all|scripted|builtin|alias|forwarder|object|setter|nsfproc? ...

/obj/ info object methods ... ?-type all|scripted|builtin|alias|forwarder|object|setter|nsfproc? ...

Method and configure parameter reform, Part 3: - added

/obj/ info lookup object variables -> list of handles

/obj/ info variable definition|name|parameter /handle/

- nx.tcl: added forward compatible scripted implementation of "lmap"

- nsf.c: handle names for private slots in pattern provided to AddSlotObjects(),

used e.g. in "info lookup slots /pattern/"

Method and configure parameter reform, Part 2: In order to streamline the interface further, we tried to follow the idea to use "... info /plural word/" to obtain a set of handles, and then a separate call to obtain the details. Therefore, we replaced

/cls/ info slot objects

/cls/ info slot definitions

/cls/ info slot names

/obj/ info object slot objects

/obj/ info object slot definitions

/obj/ info object slot names

/obj/ info lookup slots

by

/cls/ info slots ?-type /type/? ?-closure? ?-source all|application|baseclasses? ?/pattern/?

/obj/ info object slots ?-type /type/? ?/pattern/?

/obj/ info slot definition /obj/

/obj/ info lookup slots ?-type /type/? ?-source all|application|baseclasses? ?/pattern/?

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
