Starting with Haskell textmate as a basis for Bluespec Classic syntax highlighting. We started from https://github.com/JustusAdam/language-haskell
First, install the JavaScript dependencies with
npm install
(you only need to do this once).
To build the syntax rules and create the VSCode extension package, run
make
npm run package
Finally, you can install it either from the GUI or from the command line by running
code --install-extension ./language-bh-*.vsix
and then restarting VSCode.
