Version 0.1 - Jan 4 2009
	- First experimental release

Version 0.2 - Feb 14 2009
	- Adapt dbus-intf to the changed API of dbus-tcl version 0.8
	- Include all files needed for a full installable package

Version 0.3 - Dec 7 2009
	- Add the ability to invoke callbacks in named interpreters

Version 0.4 - Mar 3 2012
	- Run the body code in the namespace it was defined in

Version 1.0 - Aug 17 2013
	- Rename the package from dbus-intf to dbif, which allows it to be
	  easily turned into a Tcl module.
	- Install the package as a module instead of an old-fashioned package.
	- Global variable of a property is in the interp specified for body.
	- No more magic variables in a property script. The local variable has
	  the same name as the property.
	- Check if the value provided for a property matches the signature.
	- New "delete" subcommand to delete a node subtree.
	- Let dbif default return the current defaults.
	- If no defaults have been set up, set the default bus to the bus used
	  when connecting.
	- The introspect method now lists the GetAll method for properties.

Version 1.1 - Sep 6 2014
	- Add -id option to the signal subcommand to allow user specified
	  SignalID's.

Version 1.2 - Jun 18 2015
	- Implement the org.freedesktop.DBus.Properties.PropertiesChanged
	  signal.
	- Allow use of busses other than session and system.
	- Add -attributes option to specify annotations.
	- Adopt the [return -async 1] idom from dbus 2.1.
	- Provide a way to add/replace methods and signals for standard
	  interfaces.
	- Completely clean up the old signal when reusing a signalID.
	- Clean up (array) variables when they are no longer needed.
	- Fix introspection when no objects have been defined.
	- Correctly handle signals without a handler.

Basic Installation
==================

Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package.  The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package.

   The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation.  It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions.  Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').

   It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring.  Caching is
disabled by default to prevent problems with accidental use of stale
cache files.

   If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release.  If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.

   The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'.  You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.

The simplest way to compile this package is:

  1. `cd' to the directory containing the package's source code and type
     `./configure' to configure the package for your system.

     Running `configure' might take a while.  While running, it prints
     some messages telling which features it is checking for.

  2. Type `make' to compile the package.

  3. Optionally, type `make check' to run any self-tests that come with
     the package.

  4. Type `make install' to install the programs and any data files and
     documentation.

  5. You can remove the program binaries and object files from the
     source code directory by typing `make clean'.  To also remove the
     files that `configure' created (so you can compile the package for
     a different kind of computer), type `make distclean'.  There is
     also a `make maintainer-clean' target, but that is intended mainly
     for the package's developers.  If you use it, you may have to get
     all sorts of other programs in order to regenerate files that came
     with the distribution.

  6. Often, you can also type `make uninstall' to remove the installed
     files again.

Compilers and Options
=====================

Some systems require unusual options for compilation or linking that the
`configure' script does not know about.  Run `./configure --help' for
details on some of the pertinent environment variables.

   You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment.  Here
is an example:

     ./configure CC=c99 CFLAGS=-g LIBS=-lposix

   *Note Defining Variables::, for more details.

Compiling For Multiple Architectures
====================================

You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory.  To do this, you can use GNU `make'.  `cd' to the
directory where you want the object files and executables to go and run
the `configure' script.  `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.

   With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory.  After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.

Installation Names
==================

By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc.  You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.

   You can specify separate installation prefixes for
architecture-specific files and architecture-independent files.  If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.

   In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files.  Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.

   If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.

Optional Features
=================

Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System).  The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.

   For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.

Specifying the System Type
==========================

There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option.  TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:

     CPU-COMPANY-SYSTEM

where SYSTEM can have one of these forms:

     OS KERNEL-OS

   See the file `config.sub' for the possible values of each field.  If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.

   If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.

   If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.

Sharing Defaults
================

If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists.  Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.

Defining Variables
==================

Variables not defined in a site shell script can be set in the
environment passed to `configure'.  However, some packages may run
configure again during the build, and the customized values of these
variables may be lost.  In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'.  For example:

     ./configure CC=/usr/local2/bin/gcc

causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).

Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug.  Until the bug is fixed you can use this workaround:

     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash

`configure' Invocation
======================

`configure' recognizes the following options to control how it operates.

`--help'
`-h'
     Print a summary of the options to `configure', and exit.

`--version'
`-V'
     Print the version of Autoconf used to generate the `configure'
     script, and exit.

`--cache-file=FILE'
     Enable the cache: use and save the results of the tests in FILE,
     traditionally `config.cache'.  FILE defaults to `/dev/null' to
     disable caching.

`--config-cache'
`-C'
     Alias for `--cache-file=config.cache'.

`--quiet'
`--silent'
`-q'
     Do not print messages saying which checks are being made.  To
     suppress all normal output, redirect it to `/dev/null' (any error
     messages will still be shown).

`--srcdir=DIR'
     Look for the package's source code in directory DIR.  Usually
     `configure' can determine that directory automatically.

`configure' also accepts some other, not widely useful, options.  Run
`configure --help' for more details.

About
-----

DBus-Intf is a Tcl library for easily providing an introspectable DBus
interface to Tcl programs. It supports the following standard DBus interface
specifications: org.freedesktop.DBus.Peer, org.freedesktop.DBus.Properties,
and org.freedesktop.DBus.Introspectable


Features
--------

   + Provide introspection of methods, signals, and properties.

   + Support org.freedesktop.DBus.Properties.Get, Set, and GetAll calls.

   + Respond to org.freedesktop.DBus.Peer.Ping requests.


Compiling
---------

The dbus-intf package is plain Tcl. A TEA3-based build system is provided for
building the manual page and installing the package. Installing the package
generally consists of running "./configure; make; make install" in the
top-level directory. More details are available in the INSTALL file.

*** NOTE ***

Building the documentation requires the availability of the dtplite command,
which is part of the doctools package in tcllib.

\`configure' configures dbif 1.2 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/dbif]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-tcl              directory containing tcl configuration
                          (tclConfig.sh)

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  moduledir   directory in which to install Tcl modules

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.

[require [vset libname] [vset version]]
[description]

The [package [vset libname]] package provides a higher level wrapper around
the low-level D-Bus commands provided by the dbus package. The package also
provides an implementation of a number of standard D-Bus interfaces.
See [sectref "STANDARD INTERFACES"] for more information.

[para]

Access to all functions of the [package [vset libname]] package from within
a Tcl program is done using the [cmd [vset cmdname]] command. The command
supports several subcommands that determine what action is carried out.

[list_begin definitions]
[call [cmd [vset cmdname]] [method connect] \
  [opt "[option -bus] [arg bustype]"] [opt [option -noqueue]] \
  [opt [option -replace]] [opt [option -yield]] [opt "[arg name] ..."]]

Connect to a message bus and optionally request the D-Bus server to assign
one or more names to the current application.

[para]

The [option -yield] option specifies that the application will release the
requested name when some other application requests the same name and has
indicated that it wants to take over ownership of the name. The application
will be informed by a [emph NameLost] signal when it loses ownership of the
name.

[para]

The [option -replace] option indicates that the application wants to take
over the ownership of the name from the application that is currently the
primary owner, if any. This request will only be honoured if the current
owner has indicated that it will release the name on request. See also the
[option -yield] option.

[para]

If the requested name is currently in use and the -replace option has not
been specified, or the [option -replace] option was specified but the
current owner is unwilling to give up its ownership, the name request will
normally be queued. Then when the name is released by the current owner it
is assigned to the next requester in the queue and a signal is sent to
inform that requester that it is now the primary owner of the name. The
[option -noqueue] option may be specified to indicate that the name request
should not be queued.

[para]

The command returns a list of names that have successfully been acquired.

[para]

The following code can be used to allow a new instance of a program to 
replace the current one. This can be useful during program development:
[example_begin]
dbif connect -yield -replace $dbusname
dbif listen -interface [lb]dbus info service[rb] \
  [lb]dbus info path[rb] NameLost name {if {$name eq $::dbusname} exit}
[example_end]

[call [cmd [vset cmdname]] [method default] \
  [opt "[option -bus] [arg bustype]"] \
  [opt "[option -interface] [arg interface]"]]

Generally an application will perform several [cmd [vset cmdname]] commands
related to the same message bus and interface. To avoid having to pass the
same values for the [option -bus] and [option -interface] options with all
those commands, their defaults can be setup with the [cmd [vset cmdname]]
[method default] subcommand.

[para]

An interface name must consist of at least two elements separated by
a period ('.') character. Each element may only contain the characters
"[lb]A-Z[rb][lb]a-z[rb][lb]0-9[rb]_" and must not begin with a digit.

[para]

The initial value for [option -bus] is session. The initial value for
[option -interface] is taken from the first name requested for the
application in a [cmd [vset cmdname]] [method connect] command. If no
name was ever requested with the connect subcommand, it defaults to
"com.tclcode.default".

[call [cmd [vset cmdname]] [method delete] \
  [opt "[option -bus] [arg bustype]"] \
  [opt "[option -interface] [arg interface]"] [arg path]]

While there currently is no way to remove individual signals, methods, or
properties from the published interface, this subcommand allows the removal
of a complete node.

[call [cmd [vset cmdname]] [method error] [arg messageID] \
  [arg errormessage] [opt [arg errorname]]]

Send a D-Bus error message in response to a D-Bus method call. If the
[arg errorname] argument is not specified, it defaults to
"org.freedesktop.DBus.Error.Failed".

[call [cmd [vset cmdname]] [method generate] \
  [arg signalID] [opt "[arg arg] ..."]]

Generate a signal as defined by a previous [cmd [vset cmdname]] 
[method signal] command. If a body was specified with the signal definition,
the provided arguments must match the args definition for the body. Otherwise
they must match the arglist specified during the definition of the signal.

[call [cmd [vset cmdname]] [method get] [arg messageID] [arg name]]

Access additional information about a D-Bus message. Recognized names are
[arg bus], [arg member], [arg interface], [arg path], [arg sender],
[arg destination], [arg messagetype], [arg signature], [arg serial],
[arg replyserial], [arg noreply], [arg autostart], and [arg errorname].

[call [cmd [vset cmdname]] [method listen] \
  [opt "[option -bus] [arg bustype]"] \
  [opt "[option -interface] [arg interface]"] \
  [arg path] [arg name] [opt [arg arglist]] [opt [arg interp]] [arg body]]

Start listening for the specified signal and execute [arg body] when such a
signal appears on the D-Bus.

[para]

The code in [arg body] will be executed in the namespace the
[cmd [vset cmdname]] [method listen] command was issued from.

The [arg arglist] argument follows the special rules for [vset cmdname]
argument lists. See [sectref "ARGUMENT LISTS"] below for more information.

[call [cmd [vset cmdname]] [method method] \
  [opt "[option -attributes] [arg attributes]"] \
  [opt "[option -bus] [arg bustype]"] \
  [opt "[option -interface] [arg interface]"] \
  [arg path] [arg name] \
  [opt "[arg inputargs] [opt [arg outputargs]]"] [opt [arg interp]] [arg body]]

Define a method that may be accessed through the D-Bus and execute [arg body]
when the method is invoked. 
In addition to valid dbus paths, an empty string may be specified for the
[arg path] argument. This makes the method available on all paths.
The [arg inputargs] argument specifies which arguments must be provided by
the caller. The [arg outputargs] argument indicates the type of result the
method returns.

[para]

Attributes may be specified via the [option -attributes] option to provide
hints to users of your API.
See [sectref ATTRIBUTES] below for more information.

[para]

The return value resulting from executing the body will normally be returned
to the caller in a D-Bus return message. If an uncaught error occurs or the
result of body doesn't match [arg outputargs], an error message will be
returned to the caller instead.

[para]

The body code recognizes an additional [option -async] option for the Tcl
[cmd return] command. When that option is specified with a true boolean
value ([const true], [const yes], [const 1]), the return value from the body
will not automatically be returned to the caller. A response message should
then be generated using the [cmd [vset cmdname]] [method return] or
[cmd [vset cmdname]] [method error] subcommands.

[para]

An additional variable [var msgid] will be passed to the method body. This
variable contains a messageID that may be used in combination with the
[method get], [method return], or [method error] subcommands. The messageID
remains valid for a period of time (default 25 seconds), or until a response
has been returned to the caller, whichever happens first.

[para]

The code in [arg body] will be executed in the namespace the
[cmd [vset cmdname]] [method method] command was issued from.

The [arg inputargs] and [arg outputargs] arguments follow the special rules
for [vset cmdname] argument lists.
See [sectref "ARGUMENT LISTS"] below for more information.

[call [cmd [vset cmdname]] [method property] \
  [opt "[option -access] [arg mode]"] \
  [opt "[option -attributes] [arg attributes]"] \
  [opt "[option -bus] [arg bustype]"] \
  [opt "[option -interface] [arg interface]"] \
  [arg path] [arg name]?:[arg signature]? [arg variable] \
  [opt "[opt [arg interp]] [arg body]"]]

Define a property that may be accessed through the D-Bus using methods defined 
by the org.freedesktop.DBus.Properties standard interface. The [arg variable]
argument defines the global variable holding the value of the property.

[para]

The [option -access] option specifies whether the property can be viewed
and/or modified through the D-Bus. Valid access modes are [const read],
[const write], and [const readwrite]. If no access mode is specified, it
defaults to readwrite.

[para]

Attributes may be specified via the [option -attributes] option to provide
hints to users of your API.
See [sectref ATTRIBUTES] below for more information.

[para]

The code in the optional [arg body] argument will be executed when the
property is modified through the D-Bus. During the execution of [arg body]
the global variable will still have its original value, if any. The new
value for the property is passed to the script as an argument with the same
name as the property. If execution of [arg body] results in an error, the
global variable will not be modified. This allows restrictions to be imposed
on the value for the property.

[para]

The code in [arg body] will be executed in the namespace the
[cmd [vset cmdname]] [method property] command was issued from or, if a slave
interpreter was specified, in the current namespace of that slave interpreter
at definition time.

[para]

Generating the property value only when needed can be implemented by putting
a read trace on the global variable. Example:
[example_begin]
dbif property -attributes {Property.EmitsChangedSignal false} / clock sec
trace add variable sec read {apply {args {set ::sec [lb]clock seconds[rb]}}}
[example_end]

In this example the Property.EmitsChangedSignal attribute is used to
prevent the [emph PropertiesChanged] signal being generated, which would
involve a second read of the variable.

[call [cmd [vset cmdname]] [method return] [arg messageID] \
  [arg returnvalue]]

Send a D-Bus return message in response to a D-Bus method call. The provided
[arg returnvalue] must match the signature specified earlier in the
[cmd [vset cmdname]] [method method] command for the method.

[call [cmd [vset cmdname]] [method signal] \
  [opt "[option -attributes] [arg attributes]"] \
  [opt "[option -bus] [arg bustype]"] \
  [opt "[option -id] [arg signalID]"] \
  [opt "[option -interface] [arg interface]"] \
  [arg path] [arg name] \
  [opt "[arg arglist] [opt "[opt [arg interp]] [arg args] [arg body]"]"]]

Define a signal that the application may emit using the [cmd [vset cmdname]]
[method generate] subcommand. Signals are referred to by their SignalID.
If [option -id] is specified, it is used as the SignalID. Otherwise a new
unique identifier is generated. Specifying an existing SignalID replaces
the previously defined signal.

[para]

Attributes may be specified via the [option -attributes] option to provide
hints to users of your API.
See [sectref ATTRIBUTES] below for more information.

[para]

The command returns the SignalID of the newly created signal.

[para]

If the optional [arg args] and [arg body] arguments are specified, body
will be executed when the signal is transmitted on the D-Bus as a result
of the [cmd [vset cmdname]] [method generate] subcommand. It is the
responsibility of the body code to produce a return value that matches
the specified arglist.

[para]

The code in [arg body] will be executed in the namespace the
[cmd [vset cmdname]] [method signal] command was issued from.

If any uncaught error happens during the execution of the body code, the
[cmd [vset cmdname]] [method generate] command will also throw an error with
the same error message. 

When the body code comes to the conclusion that the signal doesn't need to
be sent after all, it may abort the operation by returning using
[lb]return -code return[rb].

The [arg arglist] argument follows the special rules for [vset cmdname]
argument lists. See [sectref "ARGUMENT LISTS"] below for more information.

[para]

In addition to valid dbus paths, an empty string may be specified for the
[arg path] argument. This makes the signal available on all paths. In this
case a body must be provided and the body code must provide a path in the
[option -path] option to the [cmd return] command.
For example: The following helper proc could be used to allow providing a
path to the [cmd [vset cmdname]] [method generate] command in front of the
signal arguments:
[example_begin]
proc stdsignal {path args} {
    # Single argument signal bodies are not expected to produce a list
    if {[lb]llength $args[rb] == 1} {set args [lb]lindex $args 0[rb]}
    return -path $path $args
}
[example_end]

[list_end]

[section "VALID NAMES"]

The [vset libname] package enforces some limitations on names used with the
[cmd [vset cmdname]] subcommands. All names must only use the characters
"[lb]A-Z[rb][lb]a-z[rb][lb]0-9[rb]_". This limitation applies to method
names, property names, signal names, and argument names. Out of this group,
only argument names may begin with a digit.

[para]

Interface names and error names must consist of at least two elements
separated by a period ('.') character. Each element must only contain the
characters "[lb]A-Z[rb][lb]a-z[rb][lb]0-9[rb]_" and must not begin with a
digit.

[para]

D-Bus names for applications must follow the same rules as interface names,
except that also dash ('-') characters are allowed. Unique D-Bus names begin
with a colon (':'). The elements of unique D-Bus names are allowed to begin
with a digit.

[para]

Paths must start with a slash ('/') and must consist of elements separated
by slash characters. Each element must only contain the characters
"[lb]A-Z[rb][lb]a-z[rb][lb]0-9[rb]_". Empty elements are not allowed.

[section "ARGUMENT LISTS"]
Due to the fact that the D-Bus specification works with typed arguments, a
slightly modified method for specifying argument lists has been adopted for
the [vset libname] package. The normal Tcl argument list as used with the
[cmd proc] and [cmd apply] commands may still be used. In that case all
arguments will be of the string type. To specify a different type, the
variable name must be followed by a colon and the D-Bus signature
specification for that argument. Example: to define the count argument as
a 32-bit integer, it should be specified as count:i.

[para]

The following argument types are available:
[list_begin definitions]
[def s] A UTF-8 encoded, nul-terminated Unicode string.
[def b] A boolean, FALSE (0), or TRUE (1).
[def y] A byte (8-bit unsigned integer).
[def n] A 16-bit signed integer.
[def q] A 16-bit unsigned integer.
[def i] A 32-bit signed integer.
[def u] A 32-bit unsigned integer.
[def x] A 64-bit signed integer.
[def t] A 64-bit unsigned integer.
[def d] An 8-byte double in IEEE 754 format.
[def g] A type signature.
[def o] An object path.
[def a#] A D-Bus array type, which is similar to a Tcl list. The # specifies
the type of the array elements. This can be any type, including another
array, a struct or a dict entry.
[def v] A D-Bus variant type. Specifying this type will cause the code to
automatically determine the type of the provided value (by looking at the
internal representation).
[def (...)] A struct. The string inside the parentheses defines the types of
the arguments within the struct, which may consist of a combination of any
of the existing types.
[def {{##}}] A dict entry. Dict entries may only occur as array elements. The
first # specifies the type of the dict key. This must be a basic type
(one of 'sbynqiuxtdgo'). The second # specifies the type of the dict value.
This can again be any existing type.
[list_end]

[para]

Argument lists may contain optional arguments. The use of optional arguments
will result in multiple prototypes being reported for the object when
introspected. The special meaning of the [const args] argument does not
translate well in the D-Bus concept. For that reason using [arg args] as the
last argument of an argument list should be avoided.

[section "STANDARD INTERFACES"]

A number of standard interfaces have been defined in the D-Bus specification
that may be useful across various D-Bus applications.

[subsection org.freedesktop.DBus.Peer]
[list_begin definitions]
[def [emph org.freedesktop.DBus.Peer.Ping]]
Returns an empty response.

[def [emph org.freedesktop.DBus.Peer.GetMachineId]]
Returns a hex-encoded UUID representing the identity of the machine the
application is running on.
[list_end]

[subsection org.freedesktop.DBus.Introspectable]
[list_begin definitions]
[def [emph org.freedesktop.DBus.Introspectable.Introspect]]
Returns an XML description of the D-Bus structure, including its interfaces
(with signals and methods), objects below it in the object path tree, and
its properties.
[list_end]

[subsection org.freedesktop.DBus.Properties]
[list_begin definitions]
[def [emph org.freedesktop.DBus.Properties.Get]]
Returns the value of the specified property. Only valid for properties with
read or readwrite access.
[def [emph org.freedesktop.DBus.Properties.Set]]
Changes the value of the specified property. Only valid for properties with
write or readwrite access.
[def [emph org.freedesktop.DBus.Properties.GetAll]]
Returns a dict of all properties with read or readwrite access.
[def [emph org.freedesktop.DBus.Properties.PropertiesChanged]]
This signal is emitted when one or more properties change.
The behavior for individual properties may be influenced by their
Property.EmitsChangedSignal attribute. See [sectref ATTRIBUTES] below.

[para]

All applicable property changes are collected and reported via a single
[emph PropertiesChanged] signal per path/interface/bus combination when the
application enters the idle loop. The signal may also be generated on demand
via the command: 
[list_begin definitions]
[list_begin definitions]
[def "[cmd [vset cmdname]] [method generate] PropertiesChanged\
[arg path] [opt [arg interface]] [opt [arg bus]]"]
[list_end]
[list_end]

[para]

The functionality for automatically populating this signal is implemented
via variable traces. If this feature is not needed, you can avoid the
associated overhead by redefining the PropertiesChanged signal id to your
own version.
To completely get rid of the signal, you can use the following code snippet
before defining any other part of your dbus interface:
[example_begin]
package require dbif
dbif signal -id PropertiesChanged / foobar
dbif delete /
[example_end]

[list_end]

[section "ATTRIBUTES"]
Attributes may be specified as a list of key/value pairs for methods,
signals, and properties. These attributes are reported via annotations in
the XML description obtained via an [emph Introspect] method call.
Annotations may be used to provide hints to users of your API.

[para]

Some well-know attributes are (default, if any, shown in italics):
[list_begin definitions]
[def Description]
Provide a short 1-line description of the method, signal or property.
[def Deprecated]
Indicate that this method is deprecated (true, [emph false]).
[def Method.NoReply]
This method may not produce a reply (true, [emph false]). For example if you
provide a method to exit your application.
[def Method.Error]
This method may throw the indicated Exception in addition to the standard
ones.
[def Property.EmitsChangedSignal]
Indicates whether a change to the property is reported via the 
[emph PropertiesChanged] signal ([emph true], false, invalidates, const).
[para]
The value of this attribute, if specified, is also used internally to
influence the automatic generation of the [emph PropertiesChanged] signal.
[list_begin definitions]
[def true]
The signal is emitted with the value included. This is the default.
[def false]
The signal is not automatically emitted on a change.
Parties interested in the property should obtain it every time they need it.
The application code may still emit a [emph PropertiesChanged] signal
whenever desired.
This may be used for properties that are implemented with a read trace on
the global variable.
[def invalidates]
The signal is emitted but the value is not included in the signal. This may
be useful for properties that change much more frequently than they are
expected to be queried, and/or have large values.
[def const]
The property never changes its value during the lifetime of the object it
belongs to, and hence the signal is never emitted for it.
