- the ability to extract a list of plugin object names from a given shared library ( I assume that your library allows to have several plugin types in the same shared library)
Could be queried using the bool res = lib.search_symbol("some_name_of_the_plugin")
That's not what I meant. You're suggesting to find a known symbol. I was suggesting to find the list of names for the existing (unknown) plugins.
This can be currently achieved using the following: // in plugin/dll namespace foo { std::vector<std::string> list_plugins(); } BOOST_PLUGIN_ALIAS(foo::list_plugins, list_plugins) // in code that uses plugin shared_library lib(path_to_lib); auto plugins = lib.get<std::vector<std::string>()>("list_plugins"); for (auto& s: plugins) { ... lib.get</**/>(s) ... } Hmmm... This does not look user-friendly. I could do some experiments with putting the aliased names into a separate section of the binary and iterating over values in that section. Will iteration over BOOST_PLUGIN_ALIASed symbols suit you? Iterating over all the exported symbols does not look useful: there;ll be a lot of mangled names and sompiler-specific trash. -- Best regards, Antony Polukhin
