This improves usability of sdbus-c++ in downstream CMake projects. CMake options now have `SDBUSCPP_` prefix so potential conflicts with downstream options/variables are minimized. Also, all configurable options and variables are placed in a single place in the root CMake file.
This switches from a raw pointer to std::optional type to pass prospective call errors to the client (using std::optional was not possible years back when sdbus-c++ was based on C++14). This makes the API a little clearer, safer, idiomatically more expressive, and removes potential confusion associated with raw pointers (like ownership, lifetime questions, etc.).
This makes D-Bus proxy signal registration more flexible, more dynamic, and less error-prone since no `finishRegistration()` call is needed. A proxy can register to a signal at any time during its lifetime, and can unregister freely by simply destroying the associated slot.
This improves the D-Bus object API registration/unregistration by making it more flexible, more dynamic, closer to sd-bus API design but still on high abstraction level, and -- most importantly -- less error-prone since no `finishRegistration()` call is needed anymore.
* feat: add async property get/set convenience support classes
* feat: add no-reply and async overloads to Properties_proxy
* feat: add convenience functions for GetAll functionality
* test: add tests for new functionality
* add codegen IDL support and documentation
Allow to use human readable chrono literals to specify method call
timeout. The change is backward compatbile - if no unit is provided,
the fallback is "us".
Example:
<annotation name="org.freedesktop.DBus.Method.Timeout" value="500ms"/>
This patch is required if EXPAT library is installed in non-standard location.
Without 'target_include_directories' cmake will find EXPAT library:
...
-- Found EXPAT: .../lib/libexpat.a (found version "2.2.10")
...
But 'xml.cpp' compilation will fail with error:
...
tools/xml2cpp-codegen/xml.cpp:7:10: fatal error: expat.h: No such file or directory
7 | #include <expat.h>
...
- add a list of c++ keywords and common defines
- sanitize names so that there are no functions/args with names that are reserved in c++
