Refactoring Strategies

The design of Stratego specifications can be improved by ReFactoring. Here is a list of refactorings. Please add to the list if you use missing refactorings.

Refactorings

• SplitChoice

• Extract Strategy: take out a sub-expression from a strategy definition and give a name

• Extract Rule

• Inline Strategy

• Inline Rule

• Rename Label/operator

• Translate Strategy Into Rule: a strategy of the form ?t1; s1; ...;!t2 can be replaced by a rule

• Translate Rule Into Strategy: a rule with trivial lhs and rhs, but complex condition is often better expressed as a strategy (pipeline)

• Extract Module: place a set of rules and strategies in their own module
