How can I create a menu in Visual Studio Code (VSCode) to facilitate code generation? Are there any recommended sources or code repositories that provide examples or guidance on implementing this functionality
VScode is not a "menu" driven user-interface. So typically there are other ways of interaction. The best thing is to register a "command", such it will appear in the Command Palette.
From Rascal the most easy-to-use feature for registering commands is to insert lenses into the editor for the DSL. If you click on such a lense a command will be activated that you can handle in Rascal directly.
There is a demo here
But it amounts to registering lenses and the executors:
// extend the set of possible commands, with possible parameters:
data Command = doSomething(start[Program] program);
// detect places to put lenses:
rel[loc,Command] myLenses(start[Program] input)
= {<input@\loc, doSomething(input /* any parameter to the command */, title="This is what the user sees!")>};
// a command handler:
value myCommandHandler(doSomething(start[Program] input)) {
... do anything here, possible using features from util::IDEServices...
return ("result": true);
}
And those myCommandHandler and myLenses functions would be registered with the language as Contributions.
If the code generator adds code to existing files, it makes sense to use util::IDEServices::registerDocumentEdits, because that will integrate with open editors and the undo stack. Otherwise you can just write files to disk using the IO module (writeFile)
