How to Build and Install the VSCode Extension

[ballcoach12]

Hey guys,

I have a grammar that is giving me problems and it might help me to have a railroad diagram generated from my grammar. I see that this feature is in the upcoming 2.0.0 release, which is not out yet, so I want to know if I can feasibly build a VSIX for the VSCode package so that I can install it and get access to the new feature as a preview.

I don't see any npm package scripts that appear to output the VSIX. If I recall correctly, VSIX is just an archive format, so maybe I need a different tool in order to generate it? How can I build the extension so that I can use it to preview the railroad diagram feature?

Thanks!

Hey @ballcoach12,

you can run vsce package (you will need to run npm i -g vsce first) in the langium-vscode directory to generate the .vsix file. Alternatively just run the Run Grammar Extension debug config and open your project in the newly opened vscode window. That should yield you the same effect.

Thank you, Mark. Got it up and running quickly. The railroad diagram is a nice addition!
