Merge branch '2.0.0-develop' of ssh://alice.wu-wien.ac.at/usr/local/src/git-repo/xotcl into 2.0.0-develop

- xotcl2.tcl: cleanup of forward implementation - xotcl2.tcl: provide debug version of default init method

- nx.tcl: cleanup of forward implementation

- Fixed an issue when accessing partly initialised NsfParamDefs (created e.g. by [::nsf::methodproperty ... returns]) from [info method] subcommands, previously leading to invalid memory accesses. Added a test to tests/returns.test. - Minor correction: xotcl2's method_handle_to_xotcl was not aware of the change to "class-object" as scope modifier.

- fixed bug in xotcl 2.0 "info forward" - extended regression test

Accomplishments: - Completed a first version of the sandboxed (partial) evaluation of Tcl source artifacts (packages, script files, C extensions) based on a dedicated child/slave interp environment: see ::nx::doc::Sandbox; the test suite and the test documentation builts run on it. - Based on this infrastructure, we can now generate a snapshot of a program's structure to be documented (and contrast it to the explicitly documented structure). - Added simplistic css sprites for visualising the doc entity status (extra, missing, mismatch, complete); see also library/lib/doc-assets/status.svg and library/lib/doc-assets/status.png - The entity status is printed optionally along with the print name of an entity - Added switch-like parts to represent properties of doc entities: @deprecated, @stashed, @c-implemented, @syshook. The implementation and use of ::nx::doc::SwitchAttribute should be reviewed after having figured out how to proceed using "switching" objparams. - I provide a multi-property dispatcher as doc-syntactic sugar and for mere convenience: @property

Various:

- Corrected some div-boxing mess in the templates

- Added a filtered helper to process entity collections

- Made the mixin layer infrastructure more symmetric (a revoke operation).

- Added tracers for ::nsf::method and ::nsf::alias (remains to be completed)

- Renamed ::nx::doc to ::nx::processor and turned it into another

mixin layer to trace the doc entity creation in e.g. readin()

- Companion (*.nxd) files: Revised the handling of companion

files. Temporarily moved generic/nsf.nxd in the top-level

directory. We need to find a permanent place as its location is

currently derived from the location of the shared extension. A

candidate is doc/ but this is not linked to the shared extension

location at all.

- processor.readin() now returns a collection of entities created

during its execution.

- Improved robustedness and orthogonality: destroy hooks; the

tag-dispatcher can now handle empty comment lines; when placing NSF

object tracer, we now use the freshly added introspection of an

object system's method aliases.

- fix typo

- rebuild pkgIndex.tcl more eagerly - added error handler to pkg_mkIndex when called via "make libraries-pkgindex" * just show warning and errors when rebuilding pkgIndex files * stop make in case of errors in pkg_mkIndex

- xotcl2: fixed and completed results of "info instforward" and "info forward"

Please enter the commit message for your changes. Lines starting

- serializer: fixed handling of nsf::configure options

- nx.tcl: removed debugging output - nx.tcl: added syntactic sugar to "method" and "alias" for return value checking. One can write now: Class create C { :public method foo {a:int b:int} -> int { return [expr {$a + $b}] } } - extended regression test

- xotcl2.tcl: added empty namespace eval to make package indexer happy

- provide a more explicit way to handle resourcing after a "package forget" in the info methods (similar to Stefan's suggestion).

- changed relation handling by evaluating the relationcmd in the parent context to keep evaluation order. - extend introspection "nsf::configure objectsystem": the command returns now all system methods in the syntax of nsf::createobjectsystem - "nsf::createobjectsystem" creates now a warning when an existing objectsystem is redefined and ignores the new definition attempt. This was done with the purpose to allow "package forget nx; package require nx" - Allow overwriting of redefine protected method during bootstrap to ease "package forget nx; package require nx" - forward had just "-objscope", no general "-frame method|object". Since forwarder have client data, they always push a method frame. So, the situation is different to nsd::alias and ::nsf::dispatch. Therefore, the flag "-objscope" was renamed to "-objectframe" to provide better consistency with "-frame object" - fixed bug, where error handling of invalid options in ForwardProcessOptions() could lead to a crash - return forwardoption "-earlybinding" via instrospection - extended regression test

- disallow object parameter of type "switch" to avoid possible confusion between (a) providing a value for the o.p., (b) calling it as a setter, and (c) calling it as a getter. For providing a value, no arg is used for switch. For calling a setter, it is necessary to provide a value even for a switch. - disallow type "switch" in setter definiton (use boolean instead) - disallow type "switch" for positional arguments (use boolean instead) - extended regression test

- added "nosetter" automatically, when attribute "<name>:method" is used

- improving error messages from argument parser - test "namespace current" and "self" in "contains" and "slots" regression test

- fix escaped duplicate line

- activated SKIP_LAMBDA in nsfCallstack. As a consequence, we disallow resolving self/my ... from tcl-proc frames (use uplevel if necessary, avoid "namespace eval")

- fix wrong "self" inside contains

- added new contains definition based on "apply" instead of "namespace eval". Main intention is to replace SKIP_LEVELS by SKIP_LAMBDA - added functionality to use ":attribute contains:method,nosetter" - added regression test for contains and attributes of type method

- fixed scoping issue, when "-volatile" was used for object creation - added regression test for interaction between filters and function resolver (and volatile) - reactivated new volatile test in destroy.test - undone temporary fixes for volatile in serializer and nx.tcl
