- new command nsf::method::forward::property in analogy to nsf::method::property for reading+writing introspection of forwarders (important for serializer, when different target objects are specified, to map the per-object forwarder) - extended regression test - bumped version number of serializer to 2.1

- serializer: keep parameter properties in xotcl parameter lists

nx.tcl: pluralism reform part 2 - changed methods /cls/ info subclass -> /cls/ info subclasses /cls/ info superclass -> /cls/ info superclasses /cls/ mixin ... -> /cls/ mixins /cls/ filter ... -> /cls/ filters /cls/ object mixin ... -> /cls/ object mixins /cls/ object filter ... -> /cls/ object filters - changed configure parameters /cls/ configure -mixin -> /cls/ configure -mixins /cls/ configure -filter -> /cls/ configure -filters /obj/ configure -object-mixin -> /obj/ configure -object-mixins /obj/ configure -object-filter -> /obj/ configure -object-filters - added handling for calling relationslot with unknown sub method

- we must replace ::get command with ::set commands for reastablishing relationships

- renamed nsf::relation to nsf::relation::set and added nsf::relation::get in accordance with nsf::var::get

nx.tcl, xotcl2.tcl: - use value=* as names for interally called and forwarder-called accessor methods - disallow "assign" for nx::variableSlots

build-process: - replace make.tcl by the much simpler mkIndex.tcl: * Does not use pkg_mkIndex * Does not load binary files (problem for cross compiling) * Requires package provide with constant in one line.

nsf.c: - fix case, where NsfDStringPrintf() failed (when print llength including \0 was 1 byte longer than print buffer) - make sure, that the list kept for the cached parameter is just built from unshared objects; otherwise Tcl append will abort

nx.tcl:

- new package "nx::volatile"

- don't define configure parameter "-volatile" per default;

use "package req nx::volatile" instead

- don't define per method "volatile" per default;

use "::nsf::method::require ::nx::Object volatile" instead

- get rid of -volatile in nx.tcl and serializer

- update/extend regression test

- restore traces after object-serialize

- don't rely on the existence of a "trace" method

nsf.c: - new command ::nsf::object::alloc /class/ /obj/ ?/script/? alloc an object and execute script in the context. Can be used to regenerate an object in a old state.

serializer:

- fixed loading of objects with required data in the blueprint

(many thanks for david hopfmueller for reporting this)

- make use of nsf::object::alloc (1 command instead of 1 create + 2 evals)

- these changes imprived laading time of blueprint by about 25%

- Tcl's "package present" raises an error if the package is not present

- fix object mehtod serializeExportedMethod: targetName might have been uninitialized

- keep packages versions from 2.0 and 1.0 disjoint

- make version management simpler and freeze XOTcl 1.* versions In order to avoid bad interactions between XOTcl 1.0 and XOTcl 2.0 the version dependency in 1.0 where changed to "package require -exact ... 1.0" where possible, and the provides where upgraded to 1.0 in most cases

serializer.tcl - added flag -objmap to Serialzer.deepSerialize to make serialzer usable for copying (-map is to coarse) - extended regression test

- 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)

- 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? ...

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

- fix xotcl instance method serialization (still not covered in regression test)

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
