This changeset fixes a huge pile of problems, as indicated in the error log of the Doxygen run after merging all the recent Doxygen improvements unfortunately, auto-linking does still not work at various places. There is no clear indication what might be the problem. Possibly the rather unstable Sqlite support in this Doxygen version is the cause. Anyway, needs to be investigated further.

/** @file config-facade.h
|
|
** The lumiera::Config wrapper class addresses two issues.
|
|
** First, it registers startup and shutdown hooks to bring up the config system
|
|
** as early as possible. Later, on application main initialisation, the global
|
|
** config interface is opened and wrapped for convenient access from C++ code.
|
|
**
|
|
** @note This was created as part of a first draft towards an application
|
|
** wide configuration system. Later (around 2012) it became clear that
|
|
** we can not judge the requirements for such a system yet, so we deferred
|
|
** the topic altogether. Meanwhile, this facade is sporadically used to
|
|
** mark the necessity to retrieve some "parametrisation values".
|
|
** @warning as a preliminary solution, the original configuration system draft
|
|
** was detached and replaced by an _ini file solution_ based on lib Boost.
|
|
**
|
|
** @todo there ought to be an external Interface for the Config subsystem.
|
|
** But the full-blown Config system isn't implemented yet anyway
|
|
**
|
|
** @see config.h
|
|
** @see lumiera::AppState
|
|
** @see main.cpp
