Jochen Theodorou commented on GROOVY-8570: ------------------------------------------ "Groovy-to-idiomatic-Groovy converter" is what I did mean, yes. And I don't think that something like gofmt would take up that much resources once the initial work has been done > Support Warnings in Groovy Compiler > ----------------------------------- > > Key: GROOVY-8570 > URL: https://issues.apache.org/jira/browse/GROOVY-8570 > Project: Groovy > Issue Type: New Feature > Components: Compiler > Affects Versions: 3.0.0-alpha-3 > Reporter: mgroovy > Priority: Major > > * To warn Java developers using e.g. non-idiomatic Groovy constructs which > only exist to support copy-and-paste Java-to-Groovy code compatibility, The > Groovy compiler should support compiler warnings in addition to compiler > errors. > * Warnings should by default only be emitted in special circumstances such > as the one described above, and not spam developers with an endless stream > of, often subjectve, messages on "how to use Groovy correctly". > * Sample warnings: > # WARNING: Using curly braces Java style array literals (\{...}) is not > idiomatic Groovy. To avoid confusion with Groovy closures, it is recommended > to use the performance-identical Groovy square bracket list literal syntax > ([...]) instead. > # WARNING: The 'var' keyword is currently only an alias to 'def' (i.e. > Object) in Groovy. To get reassignment type safety use an explicit type > instead. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
