# Prerequisites: * Needs Java 8 already installed(for BashLog) * pip install mercylog-bashlog

# Tutorial Check out the [tutorial/introduction](https://github.com/RAbraham/mercylog-bashlog_tutorial) to Mercylog

# Short Introduction ```python import mercylog_bashlog

m = mercylog_bashlog.BashlogV1() _ = m._

father = m.relation('father') mother = m.relation('mother') facts = [

father('Aks', 'Bob'), father('Bob', 'Cad'), father('Yan', 'Zer'), mother('Mary', 'Marla'), mother('Marla', 'Kay'), mother('Jane', 'Zanu'),

]

X = m.variables('X')

paternal_grandfather = m.relation('paternal_grandfather') maternal_grandmother = m.relation('maternal_grandmother')

def transitive(head, clause):

X, Y, Z = m.variables('X', 'Y', 'Z') return head(X, Z) <= [clause(X, Y), clause(Y, Z)]

rules = [

transitive(paternal_grandfather, father), transitive(maternal_grandmother, mother)

]

print(m.run(facts, rules, [paternal_grandfather(X, _)])) # ['Aks']

print(m.run(facts, rules, [maternal_grandmother(X, _)])) # ['Mary']
