* configure, configure.ac, nx.tcl, pkgIndex.tcl, xotcl2.tcl, pkg.vc: Bump version to 2.2.0.

  1. … 6 more files in changeset.
Slot trace reform: - redesign of slot interface of traces from * variables contains cmds and variable references to * slot specific methods with the same interface as slot-setters - new: * specify flag "-trace" with a list of values "get", "set", "default" * when flag is set, a trace will be registered calling methods value=get obj variable value=set obj variable value value=default obj variable on the slot (actually the first two are identical with the methods used for slot-defined accessors) - updated regression test * new flag "-notrace" for "nsf::var::set" and "nsf::var::get"

  1. … 9 more files in changeset.
- provide actual pkgIndex files

  1. … 1 more file in changeset.
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.

xotcl2: - fixed "... info defaults ..." and "... info instdefaults ..." emulation in XOTcl 2 - fixed error message - extended regression test - bumped revision of nsf/xotcl/nx to 2.0b6

  1. … 9 more files in changeset.
- bumped version number to 2.0b5 - tested with NaviServer and OpenACS (new version of nx needs as well a newest NaviServer, since ns_cache implementation needs to be objectified; newest NaviServer version works as well with older nx)

  1. … 4 more files in changeset.
- renamed "package require nx::class" to "package require nx::class-method" in analogy to "nx::plain-object-method"

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

- nx.tcl: don't use mixins in method "contains", but remap the new implementation. If there are ten thousands of classes defined, adding mixins to the root meta-class degrades linearly on the number of classes defined (the mixin paths for all classes must be invalidated). This might be a problem for frequent "contains" invocations. - bup version numbers for nx, xotcl2 and nsf to 2.0b2

  1. … 5 more files in changeset.
- nx.tcl, xotcl.tcl: * remove proc "register_system_slots" since 'rename register_system_slots ""' fails on aolserver * bump version number to 2.0b1

  1. … 4 more files in changeset.
- library/lib/nx-zip.tcl: refactored implementqtion, improved utf-8 file-name handling (which is a mess in pkzip)

  1. … 4 more files in changeset.
- use same version numbers in nsf, nx and xotcl2

  1. … 4 more files in changeset.
- library/nx/nx-zip.tcl: added a zip file generator as package

- use prefix sub= for methods invoked on "object as method" - change further instances of "my connection" to "[self]::connection" in xo*comm*

  1. … 9 more files in changeset.
- made the "next scripting laguage" a own, loadable tcl package (currently named nx, name is subject of change) - predefined.tcl is now pretty minimal.
