Developer's Guide

Source tree layout

• config
  • this directory holds m4 macro processor files and bits of the autotools build system
• contrib
  • this directory includes maintainer scripts and other things that aren't *directly* part of CVC4
• doc
  • documentation
• src
  • core
    • the core of CVC4: the expression package, the core engines, ...
  • include
    • most include files (some private include files are also in parser and sat)
  • parser
    • parsers for supported CVC4 input formats
  • sat
    • propositional parts of CVC4; these include imported minisat sources

Coding guidelines

File and directory names

1. Files should be all lowercase, with CamelCase classes in header files named camel_case.h (and their implementations in camel_case.cpp);
2. File extensions .cpp and .h are generally preferred, with .ypp and .lpp for yacc and lex inputs---an exception is made for headers when autotools wants to output parser definitions as (e.g.) pl.hpp;

Source file layout

Class header files

1. A class named ThisIsAClass is guarded by a preprocessor macro __CVC4_THIS_IS_A_CLASS_H. Its definition is in src/include/this_is_a_class.h.
2. Everything should be in the CVC4 namespace.

Class implementation files

1. A class named ThisIsAClass should have its implementation under src/ in this_is_a_class.cpp.

Imported sources

1. **IMPORTANT:** For imported sources, make sure to add an exclusion to the contrib/update-copyright.pl script so that a CVC4 copyright isn't added.
