Refactoring Strategies
Stratego -- Strategies for Program Transformation
Description
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
- 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
