Hello, thanks for this very useful extension. This is a request to make it available on the Open VSX Registry to make it easier to install. Since the VSCode marketplace is proprietary, the creators of Onivim decided to use Open VSX instead more info here. Right now your extension needs to be installed from the CLI.

In package.json, you have the configuration set to ./language-configuration.json, but you have the file named to gas.configuration.json.

I'll fork it to see if it works, and I'll keep you updated. Please accept my merge request when I submit one. If you don't feel like maintaining this project any more, please add me to collaborator and I'll try my best to maintain it.

I noticed the version of github has some changes/improvements that are not published on https://marketplace.visualstudio.com/items?itemName=basdp.language-gas-x86&ssr=false#overview

Can you update this version please?

I can't find any license information for this project. Would it be possible to add a LICENSE file?

As you can see in the picture at the bottom, it looks like the language server isn't working.
Because of no information about features in the readme.md, it is not clear, what features are expected to work.
