Crystal meets Prolog
Experiment on how swi-prolog can be embedded in crystal.
- Load existing prolog files
- Define facts or rules from crystal
- Consume prolog queries in a crystal friendly way (i.e. yield)
- Goals must be single predicate with variables or atoms. (crystal vars/symbols respectively).
- Rules not defines new vars.
Install swi-prolog
brew install swi-prolog
Ensure pkg-config --libs swipl
works. You might need to
export PKG_CONFIG_PATH=/usr/local/Cellar/swi-prolog/7.2.0/libexec/lib/pkgconfig
Add this to your application's shard.yml
:
dependencies:
