.SH NAME
|
|
|
|
|
glib-genmarshal \- C code marshaller generation utility for GLib closures
|
|
|
|
|
.SH SYNOPSIS
|
|
|
|
|
|
|
|
|
|
\fBglib-genmarshal\fP [\fIoptions\fP] [\fIfiles...\fP]
|
|
|

|
.SH DESCRIPTION
|
|
|
|
|
\fBglib-genmarshal\fP is a small utility that generates C code marshallers
|
|
|
|
|
for callback functions of the GClosure mechanism in the GObject sublibrary
|
|
|
|
|
of GLib. The marshaller functions have a standard signature, they get passed
|
|
|
|
|
in the invoking closure, an array of value structures holding the callback
|
|
|
|
|
function parameters and a value structure for the return value of the
|
|
|
|
|
callback. The marshaller is then responsible to call the respective C code
|
|
|
|
|
function of the closure with all the parameters on the stack and to collect
|
|
|
|
|
its return value.
|
|
|
|
|
|
|
|
|
|
.SH INVOCATION
|
|
|
|
|
|
|
|
|
|
\fBglib-genmarshal\fP takes a list of marshallers to generate as input.
|
|
|
|
|
The marshaller list is either read from standard input or from files
|
|
|
|
|
passed as additional arguments on the command line.

convenience macro.
* Makefile.am: cleanups, marshaller generation rules.
* gmarshal.[hc]: new files with GRuntime standard marshallers.
* glib-genmarshal.c: fix log domain, support gruntime standard
marshallers, suport G_TYPE_PARAM, come with extern "C" and
#include gmarshal.h.
* glib-genmarshal.1: reflect glib-genmarshal.c updates.
* gobject.[hc]: implement object constructor. rework parameter
changed notification queueing, we support queue freezes now and
don't dispatch from an idle handler anymore.
parameter->property rename hassle.
implemented ::properties_changed and ::notify::* signals for
property change notification (the later supports property names
as details). added signal connection and named data properties.
(g_signal_connect_object): new function to setup while_alive
connections.
(g_object_class_install_property): sink properties now, since they
are initially floating.
(g_object_steal_data):
(g_object_set_data_full):
(g_object_set_data):

(g_object_freeze_notify): start queueing of property changes (freeze/
thaw calls stack).
(g_object_notify): announce changes of a certain property directly.
(g_object_thaw_notify): process queue of property changes, therefore
emitting GObject::notify::detail with detail being the changed
properties names.
(G_OBJECT_WARN_INVALID_PROPERTY_ID): saner macro variant of former
G_WARN_INVALID_PARAM_ID().
* gparam.[hc]: param specs are now initially floating and need to be
sunken with g_param_spec_sink(), support G_TYPE_PARAM values.
added G_PARAM_CONSTRUCT and G_PARAM_CONSTRUCT_ONLY parameter flags,
required by GObjectClass.constructor().
* gparamspecs.[hc]: added GParamSpecParam, GParamSpecPointer and
GParamSpecCCallback, param specs for G_TYPE_PARAM, G_TYPE_POINTER
and G_TYPE_CCALLBACK respectively.

collected from a va_list.
(g_signal_emit): emit signal, taking parameters from varargs list.
(g_signal_emit_by_name): same as g_signal_emit, working from
signal name+detail.
(signal_emit_R): return whether return_value needs to be altered.
* gtype.[hc]: set log-domain to GRuntime, i'm slowly getting to all
the points that need to reflect the upcoming rename.
melt g_type_conforms_to() functionality into g_type_is_a(), as that
is what we really want (liskov substitution principle).
assorted changes to other files due to conforms_to->is_a.
* gvalue.[hc]: implemented g_value_set_instance() that sets a value
from an instantiatable type via the value_table's collect_value()
function (based on an idea from James Henstridge <james@daa.com.au>).

boxed structure uses ref counting internally.
added g_value_set_boxed_take_ownership().
made G_TYPE_BOXED an abstract value type.

types.

arg specification.
* gobject.[hc]: cleaned up get/set property code.
added g_strdup_value_contents() to improve warnings.

of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so
validation alterations may be valid a part of the property setting
process.

nuked the value exchange API. implemented value transformations, we

C casts, real conversions need a param spec for validation, which is
why g_param_value_convert() does real conversions now.
* gvaluearray.[hc]: new files that implement a GValueArray, a struct
that can hold inhomogeneous arrays of value (to that extend that it
also allowes undefined values, i.e. G_VALUE_TYPE(value)==0).
this is exposed to the type system as a boxed type.

exchange functions as single-sided transformations.

* gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS
into G_VALUE_LCOPY(), this needs proper documenting.
* gparam.c: fixed G_PARAM_USER_MASK.
* gtype.c (type_data_make_W):
(type_data_last_unref_Wm): fixed invalid memory freeing.
* gobject.c (g_object_last_unref): destroy signal handlers associated
with object, right before finalization.
* gsignal.c (g_signal_parse_name): catch destroyed nodes or signals
that don't actually support details.
* gobject.[hc]: got rid of property trailers. nuked GObject
properties "data" and the "signal" variants.
(g_object_connect): new convenience function to do multiple
signal connections at once.
(g_object_disconnect): likewise, for disconnections.
* gparam.[hc] (g_param_spec_pool_lookup): took out trailer support.
* gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer()
as private (the latter got renamed from g_value_get_as_pointer()).
Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org>
* glib-object.h: add gvaluearray.h.
* gstring.[hc]: fixup naming of g_string_sprint*.
* gtypes.h: fixed GCompareDataFunc naming.
Wed Mar 7 09:33:27 2001 Tim Janik <timj@gtk.org>
* gobject/Makefile.am: shuffled rules to avoid excessive
rebuilds.
* gobject/gobject-sections.txt: updates.
* gobject/tmpl/*: bunch of updates, added another patch
from Eric Lemings <eric.b.lemings@lmco.com>.

added newly added gobject/ headers.
Tue Oct 24 22:09:14 2000 Tim Janik <timj@gtk.org>
* glib-object.h: added newly added gobject/ headers.
* gmesage.c: print g_message() output to stderr instead of stdout.
Wed Oct 25 20:27:02 2000 Tim Janik <timj@gtk.org>
* gtype.c (g_type_free_instance): for the moment, freeing object
structures will fill their memory portion with 0xAA. there's a
FIXME there, remove this line at a later point.
Tue Oct 24 23:10:26 2000 Tim Janik <timj@gtk.org>
* glib-genmarshal.1:
* glib-genmarshal.c: added publically installed marshaller generator.
* gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain
interface VTable from instances.
Mon Oct 23 08:28:15 2000 Tim Janik <timj@gtk.org>
* gobject.[hc]: new functions for closure maintenance:
(g_object_watch_closure): maintain validity of the object and
the closure for objects that are used as data part of a closure.
(g_cclosure_new_object): convenience function to create C closures
that have an object as data argument.
(g_closure_new_object): convenience function to create closures
that have an object as data argument.
* gclosure.[hc]: implementation of GClosure mechanism.
a closure is basically an encapsulation of a callback function
and its environment. ideally, most places supporting callback
functions will simply take a GClosure* pointer and thus unify
callback environments wrg destroy notification etc.
GClosure provides destroy notifiers for arbitrary data pointers,
reference counting, invalidation notification (it can be invalidated
which is merely a deactivate state) and a marshallinbg abstraction.
GCClosure is also provided in these files, they present a specialized
GClosure implementation for C language callbacks.
* genum.c: macro cleanups.
* gboxed.[hc]: new files, for boxed type abstraction.
(g_boxed_copy): copy a boxed structure
(g_boxed_free): free a boxed structure
(g_value_set_boxed):
(g_value_get_boxed): standard GValue functions for boxed types
(g_boxed_type_register_static): convenience function for easy
introduction of new G_TYPE_BOXED derivatives.
* gparam.[hc]: introduced g_param_type_register_static(), a short hand
for creation of new GParamSpec derived types.
* gtype.[hc]: many fixes, introduced ability to flag individual
type nodes as ABSTRACT upon registration, added value_peek_pointer()
to the value table to peek at GValue contents as a pointer for types
that support this. fixed up GValue checks.
* gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer()
to peek at the value contents as pointer.
* *.[hc]: adaptions to type macro fixes and changes in the type
registration API.
* many const corrections over the place.
Sat Oct 21 02:49:56 2000 Tim Janik <timj@gtk.org>
* gtype.c (g_type_conforms_to): this function basically behaves like
and is_a check, except that it _additionally_ features interfaces
for instantiatable types. enforce this in the second branch as well
(`type' conforms_to `type') even if `type' is not an interface type.
Fri Oct 20 15:31:04 2000 Tim Janik <timj@gtk.org>
* gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb.
* gtype.[hc]:
* gobject.c:
* gvaluetypes.c: added GTypeValueTable.value_peek_pointer and
suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT
and G_TYPE_POINTER.
Mon Aug 21 04:13:37 2000 Tim Janik <timj@gtk.org>
* gbsearcharray.[hc]: long standing needed generic implementation
of a binary searchable, sorted and dynamically sized array.

The marshaller list has to look like this:
|
|
|
|
|
.PP
|
|
|
|
|
.RS
|
|
|
|

The generated marshallers have the arguments encoded
|
|
|
|
|
in their function name. For this particular list, they
|
|
|
|
|
are
|
|
|
|
|
g_cclosure_marshal_VOID__VOID(),

g_cclosure_marshal_VOID__INT(),
|
|
|
|
|
g_cclosure_marshal_FLOAT__BOOLEAN_UCHAR().
|
|
|
|
|
.PP
|
|
|
|
|
They can be used directly for GClosures or be passed in as
|
|
|
|
|
the GSignalCMarshaller c_marshaller; argument upon creation
|
|
|
|
|
of signals:
|
|
|
|
|

GClosure *cc_foo, *cc_bar, *cc_baz;
