We am currently working on a SonarQube plugin for a DSL for my company. We have developed our language grammar using SSLR, written more than 50 rules, and our plugin is on its way to first release. My company is now interested in implementing support for the DSL in SonarLint via VSCode. I read 2 posted forms, VSCode - SonarLint - Custom language and SonarLint connected mode - support for new language, which clearly state that SonarLint was not open for third-party custom language development. We want to make sure if that changed since the forms date back to last year. If so, can we extend our implemented SSLR parser and already implemented rules? If not any general ideas, on re-implementing support for the custom language in SonarLint?
