Is it possible to define custom compiler for particular file type in IntelliJ IDEA? I found how to define custom formatting though.
I have bunch of *.proto files in my project. It would be nice if I have define external executable that compiles them into .java files that javac will further compile.
Doesn't the protobuf plugin (http://plugins.intellij.net/plugin/?idea&id=4942) do this for you?
If not, you should create a plugin and implement TranslatingCompiler there. See, for example, Groovy plugin source for the code samples.
