execution namespace reform: - add execution namespace to proc context instead of altering the namespace of the command - this fixes strange behavior of "info commands ::o::p", which might have returned "::p" - provide compatibility with Tcl 8.7a2 - extend regression test

  1. … 3 more files in changeset.
deactivate solution to the tcl87a2 problem for now, since we need a different solution with this for recursive aliases

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

  1. … 31 more files in changeset.
nsf.c: - added nsf::var::get and "::nx::var get" to provide selector based interface for variable reading (used in slotmethod get of nx::VariableSlot)

- cleanup of nx.tcl and TODO

  1. … 8 more files in changeset.
nx.tcl, xotcl2.tcl: - use value=* as names for interally called and forwarder-called accessor methods - disallow "assign" for nx::variableSlots

  1. … 12 more files in changeset.
nx.tcl: - use set/get/add as slot methods for get/configure/incremental operations - demangle slots for nx/xotcl2 further

xotcl2:

- use assign/get/add as slot methods for get/configure/incremental

operations

- use object system configuration for -slot.get and -slot.set

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

- 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? ...

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

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

- 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

- fixed bug with recursive aliases - extended regression test

  1. … 2 more files in changeset.
- make sure to use "XOTcl 2.0" instead of just XOTcl in "package req" to avoid confusions due to beta state - remove more obsolete and untested files

  1. … 56 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)

* 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)
