Hi I just finished implementing a feature with LSP4ij But I am thinking of splitting the plugin so that I will release 1 version with this implementation targeting noncommercial IDE and implementing using the Jetbrains SLP infrastructure targeting commercial IDE. Any suggestion on how to do it? …

Hey Jonathan! LSP4IJ is open source product with lots of supported LSP specification features (methods). Last time I touched JB LSP there were ~10 from more that 100 from the specification. It’s all depends on LSP4IJ license, but I’d did all in combination and with freemium subscription: some fea…
