This chapter describes how to add a parser in C and the internal API of Universal Ctags.
Before you start writing a parser in C, consider using optlib parser. Universal Ctags extends the functionality so extensively that it can implement most of functionality for the parser. See :ref:`ctags-optlib(7) <ctags-optlib(7)>` and :ref:`optlib` for details.
optlib parser is also suitable for prototyping of a parser in C.
