Datalog ABSTRACT This package contains a lightweight deductive database system. Queries and database updates are expressed using Datalog--a declarative logic language in which each formula is a function-free Horn clause, and every variable in the goal of a clause must appear in the body of the clause. The use of Datalog syntax and an implementation based on tabling intermediate results, ensures that all queries terminate. The components in this package are designed to be small, and usable on memory constrained devices. The package includes an interactive interpreter for Datalog, and a library that can be used to embed the interpreter into C programs. INSTALLATION Install using the usual "./configure; make; make install" sequence as described in the file INSTALL. If you have Lua 5.2 installed, configure with the --with-lua option. On Debian-based systems, use: $ ./configure --with-lua-suffix=5.2 CPPFLAGS=-I/usr/include/lua5.2 Datalog can be built on top of Lua 5.1 too. DOCUMENTATION This package is documented using Texinfo and a manual page. The NEWS file contains a history of user-visible changes. The ChangeLog records changes to the package. TEST SUITE The source distribution contains examples of Datalog programs used for testing that are not installed. Examples from the Texinfo manual are also included.
