This singleton class handles management of plugin search paths and plugin
discovery. Search paths are (if they exist):
* <lmms-exe-dir>/../lib/lmms: This is the common location on Unixoids
(Not included in Windows builds)
* <lmms-exe-dir>/plugins: For portable and Windows installations
* The path given by the compile define LMMS_PLUGIN_DIR
* Environment variable LMMS_PLUGIN_DIR if given
This commit also tweaks the build script to output built plugins to
"${CMAKE_BINARY_DIR}/plugins". This way lmms can find plugins during
development without the need to use `make install`.
Plugin::getDescriptorsOfAvailPlugins and ConfigManager::pluginDir were
removed.
Instead of writing QVector<Plugin::Descriptor> everywhere, mix up
iterators etc. centrally define Plugin::DescriptorList and use it
everywhere.
Additionally made pointers to Plugin::Descriptor and
Plugin::Descriptor::SubPluginFeatures::Key const in various places
so we can use ConstIterator everywhere when iterating through
Plugin::DescriptorList.
(cherry picked from commit 2287eca802)
We can safely make fillDescriptionWidget() and listSubPluginKeys()
const methods. Furthermore descriptor pointer to listSubPluginKeys()
can be const as well. Might allow more optimizations by the compiler.
(cherry picked from commit 1c76c77d22)
Most files and most of the core classes and their methods have been
renamed to match new coding style conventions:
391 files changed, 25400 insertions(+), 25598 deletions(-)
Furthermore splitted some files where model and view classes were
declared or implemented together in the same file.
Should be tested thoroughly as I might have missed renaming some virtual
methods or SIGNAL/SLOT parameters.
