Grammar Islands

As we explored expanding Rewrite's language support to Typescript and Groovy, we discovered that their AST structures were almost identical to the existing Java model. Languages like Typescript and Java which have very different tooling ecosystems have a strong resemblance even down to the way type attribution is represented on their AST models. By extracting the common AST model (including type attribution) to a C-family "grammar island" we are able to leverage the same set of base recipes that operate on that common model across all of the languages in this family!

Groovy and Gradle Support

We are excited to announce that we have introduced a parser for Groovy! This allows us to also extend this parser to provide some initial support for Gradle files.

Printing

Tree now contains a print(Cursor) method. TreePrinter has been removed. This is a consequence of the extraction of grammar islands. One of the key differences between different languages in the same family is how AST elements are rendered in source code. So the same C.VariableDecls may be represented in Java as final Integer n = 42 and in Kotlin as val n: Int = 42. Printing then depends on understanding what the root of the AST is, whether it is a Java source file or a Kotlin. Further consequences of this change:

JavaSearchResult, XmlSearchResult, etc. have been removed in favor of plain RecipeSearchResult.
