nx.tcl: - remove setter methods from BootstrapVariableSlots - reducing interface of BootstrapVariableSlots by setting methods protected

  1. … 5 more files in changeset.
- add flag "-onerror" to nsf::forward::method to handle errors during dispatch of a forwarder (not all error messags of forwarder are already transformed) - added log-level Info which prints always, e.g. for "-verbose" flag of forwarder - drop setter-rule from properties (use always forwarder) - drop "/obj/ /prop/" and "/obj/ /prop/ /value/" in favor of "/obj/ /prop/ get" and "/obj/ /prop/ assign /value/" to achieve better orthogonality with e.g. incremental properties

  1. … 16 more files in changeset.
- preserve lower bound of multiplicity when incemental is added - extend regression test

  1. … 2 more files in changeset.
- added more test cases for multiplicity and incremental

  1. … 2 more files in changeset.
nx.tcl: - Define method "value" as a slot forwarder to allow for calling value-less slot methods like e.g. "get" dispite of the arity-based forward dispatcher. - extend regression test

  1. … 2 more files in changeset.
- improve code documentation - add some more tests to the regression test suite

  1. … 2 more files in changeset.
- extend regression test

  1. … 1 more file in changeset.
- generic/nsf.c: Use GetAllClassMixinsOf() instead of TransitiveSubClasses() when invalidating per-class caches. Added two tests.

  1. … 1 more file in changeset.
nsf.c: - invalidate paramter caches of subclasses on NsfParameterInvalidateClassCacheCmd unless during shutdown. Otherwise some classes might not become aware of properties added later to superclasses. - extended regression test

  1. … 4 more files in changeset.
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

  1. … 13 more files in changeset.
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

  1. … 44 more files in changeset.
nx: - allow copy of objects with required arguments - use ::nsf::object::alloc in "copy" method - don't depend on method "trace", use directdispatch instead - remove method "-noinit" (nsf::object::alloc makes it obsolete) - extend regression test

  1. … 7 more files in changeset.
nx::test: - change test cases to newer interface - don't use "namespace import nx::*" in test cases when not required

  1. … 34 more files in changeset.
nx.tcl: - renamed variable option "-config" to "-configurable" to make its intention clearer

  1. … 11 more files in changeset.
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

  1. … 7 more files in changeset.
nsf.c - fixed potential inifinite loop in pattern matching for precedence lists - cget: make error message closer to tcl conventions - extended regression test

  1. … 4 more files in changeset.
- 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)

  1. … 17 more files in changeset.
- dropped "/obj/ info slot definition /obj/" in favor of "/slotobj/ definition"

  1. … 6 more files in changeset.
- nx.tcl: handle "incremental" in slot reconfigure - nx.tcl: change defaultAccessor to "none"

  1. … 20 more files in changeset.
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/?

  1. … 9 more files in changeset.
- syntax formatter: use /value/ for denoting placeholder in "... info method syntax ..."

  1. … 11 more files in changeset.
- added "/obj/ object variable" and "/obj/ object property"

  1. … 8 more files in changeset.
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

  1. … 43 more files in changeset.
nx.tcl: - property has now a boolean non-positional argument "-config" /obj|cls/ property ?-accessor value? ?-config boolean? ?-incremental? ?-class value? spec ?initblock? in symmetry with "-accessor" (parameter option "noconfig" is still needed to flag nsf for variables that should be initialized, which are not configurable - "/obj|cls/ info slot definitions" returns a full command (containing flags and property|variable) - extended regression test

  1. … 3 more files in changeset.
- remove debug output

- changed name "/obj|cls/ slot info definition" to "/obj|cls/ slot info definition" since result is a set - dropped parameter method "properties" - dropped "/obj/ info properties" (since "properties" or "variables" are returned")

  1. … 8 more files in changeset.
- added functiality for "cget" to call parameter-methods (e.g. "... cget -class"). The method cget calls either "/slot/ get ..." (when slot=... is provided in the parameter spec) or it assumes that the method without argument returns the value - added "::nsf::object::property /obj/ volatile" to query whether a object is volatile or not - "/obj/ cget -volatile" returns now the volatial state of the object - factored out ParameterMethodDispatch() from OConfigureMethod() - extended regression test

  1. … 9 more files in changeset.
- invalidation of per-object parameter cache * on mixin changes and * on deletion/adding of per-object slots - decactivate PER_OBJECT_PARAMETER_CACHING per default (flipping this parameter makes regression test more than 20 faster). - extended regression test

  1. … 4 more files in changeset.
- generalize handling for per-object-properties

  1. … 3 more files in changeset.
- added addtional file for regression test
