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: - 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.
- added implementation for slots with traces+types for classes - exception for incorrect defaults are thrown during slot creation - extended nsf::is, added parameter * ?-configure? -- accept configure paramter options * ?-name /name/? -- provide a parameter name for error message - simplified nx.tcl by using new nsf::is - extended regression test

  1. … 6 more files in changeset.
- added partly implementation for slots with traces+types for classes

  1. … 3 more files in changeset.
- fixed cases, where valuechangedcmd (and the other traces) did not work with "configure" method. When slot traces are used, it cleans other traces for the same operations. - extended regression test

  1. … 3 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

/cls/ info configure parameters ?pattern? -> list of params

/cls/ info configure syntax -> syntax output

/obj/ info method parameters /methodName/ ?/pattern/? -> list of params

/obj/ info method syntax -> syntax output

/obj/ info lookup configure parameter ?/pattern/? -> list of params

/obj/ info lookup configure syntax -> syntax output

/cls/ info parameter list|name|syntax /param/ -> value

  1. … 14 more files in changeset.
- syntax formatter: use /value/ for denoting placeholder in "... info method syntax ..."

  1. … 11 more files in changeset.
- parametersyntax: make placeholders explicit

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: - factored out ParameterMethodForwardDispatch() to call a parameter method defined as a forwarder the smae way from "configure" and "cget" - extended regression test

  1. … 3 more files in changeset.
- extended regression test

  1. … 1 more file in changeset.
- 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

Property reform part 1:

- disallow protection modifiers for "properties" and

add new flag "-accessor" to "property" and "variable"

This changes definitions like

Class create C {

:property {a a1}

:public property {b b1}

:protected property {c c1}

:private property {d d1}

}

to

Class create C {

:property {a a1}

:property -accessor public {b b1}

:property -accessor protected {c c1}

:property -accessor private {d d1}

}

since "properties" are always public accessible

over the "configure" and "cget" interface, but the

accessors methods might not be public. The value of

the accessor might be also "none" (specifying explicitely

that no accessor is wanted) or "", which means: use the default.

Same holds for "variable"

- disallow parameter option "incremental" and change it to a flag

of the property or variable. The motivation for this is due to

the fact, that "incremental" is a property of the accessor, and

not of the value.

old:

Class create C {

:property foo:int,incremental

:variable bar:int,incremental

}

new:

Class create C {

:property -incremental foo:int

:variable -incremental bar:int

}

- disallow "public class property" and friends since these are not needed

- removed parameter property "noaccessor"

- removed "nx::configure defaultPropertyCallProtection" and

method hook "__default_property_call_protection"

- introduced "nx::configure defaultAccessor" and

method hook "__default_accessor"

- for the time being, "defaultAccessor" is "public" for NX and XOTcl,

will be changed to "none" in NX

- extended regression test (new file properties.test)

nsf.c: - fixed parmeter syntax for required nonpos args - deactivate deletion of methods via nsf::object::delete during shutdown to avoid missing slot forwarders called from destructors

  1. … 5 more files in changeset.
nsf.c: - made argument of cget required

nx.tcl:

- added Tk-style methods "configure" and "cget"

- added additional regression test set for cget and configure
