Provide parser modules.
This is the preferred way to extend the input language by supplying dlvhex with parser modules that plug into the HEX grammar and extend the syntax for valid program input.
See the QueryPlugin and the StrongNegationPlugin for example plugins that use this feature.

Rewriter for hex-programs.
The rewriters are called on the parsed HEX program (which may have been rewritten by a PluginConverter). Hence, a rewriter can expect a well-formed HEX-program represented in ProgramCtx::edb and ProgramCtx::idb as input and must of course also take care of keeping that representation correct program.

Processes options for this plugin.
If you override this method, remove all options your plugin recognizes from pluginOptions. (Do not free the pointers, the const char* directly come from argv.) You can store configuration of your plugin using PluginData and ProgramCtx::getPluginData (see there for more information.)

Altering the ProgramCtx permits plugins to do many things, e.g., * installing model and finish callbacks * removing default model (and final) hooks * setting maxint * changing and configuring the solver backend to be used See internal plugins for example usage.
