rule-engine-dart's Issues

Allow for easier unit testing of valid/invalid syntax

not-operator for clauses

Allow for negation of a clause

not SimpleFact( amount > 10 )

support insertion of symbols in strings declared in consequences

no support for negative literals

Project Status?

What is the status of this project? It looks like there hasn't been any activity for a while, and this project never quite reached production-ready status.

Does anyone know of an alternative? I can't even seem to find a commercial option for a business rule engine native to dart/flutter.

make environmental metadata available in rules

eg. the name of the rule

allow insertion of new rules after startup

min() and max() aggregates aren't implemented

allow empty clauses (only match on type)

Support other types of dateTimes in windows

Symbols don't support numerical values in the name

      Expense( $amount2 > $amount )
                      ∧
                      #=== Error while parsing, expected [TokenType.LESS_THAN, TokenType.GREATER_THAN, TokenType.EQUALS], got 'TokenType.INTEGER' for token: '{TokenType.INTEGER:2 @ pos 108}'

Optional rewrite rule syntax

rule "..."
  when
    Clause(...)
  replacing
    Clause(...)
  then
    insert Achievement(..)
end
