Gexsys is a simple expert system framework based on GNU Guile and relational databases.

gexsys - Guile Expert System.

Overview:

A relational knowledge base framework for GNU Guile using simple tools for constructing rule based systems using relational databases.

Dependencies:

• GNU Guile - ver 2.0. or newer ( https://www.gnu.org/software/guile/ )

• guile-dbi - ( https://github.com/eestrada/guile-dbi )

• guile-dbd-sqlite3 - ( https://github.com/eestrada/guile-dbi )

• Sqlite3 - ( https://www.sqlite.org/index.html )

• grsp - https://github.com/PESchoenberg/grsp.git

Installation:

• Assuming that you already have the requisite software running on your system, get gexsys, unpack it into a folder of your choice and cd into it.

• gexsys installs as a GNU Guile library. See GNU Guile's manual instructions for details concerning your OS and distribution, but as an example, on Ubuntu you would issue:

  sudo mkdir /usr/share/guile/site/2.0/gexsys

  sudo cp *.scm -rv /usr/share/guile/site/2.0/gexsys

  or

  sudo cp *.scm -rv /usr/local/share/guile/site/2.2/gexsys

and that will do the trick.

Uninstall:

• You just need to remove /usr/share/guile/site/2.0/gexsys and its subfolders.

• If you would like to uninstall guile-dbi, you should read the specific docs for that package.

Usage:

• Should be used as any other GNU Guile library.

• See the examples contained in the /examples folder. These are self-explaining and filled with comments.
