goyacc syntax highlighting

Fork of LunicLynx/vscode-bison to hopefully get syntax highlight for goyacc

Warning: not working perfectly. It is 'good enough' for simple .y files, such as tools/cmd/goyacc/testdata/expr/expr.y file present in the official goyacc repo. From the repo this fork originated, I just replaced all the .c occurrences with .go and removed the section meta.declarations.bison, which was causing the block inside %{...%} to not be highlighted (before removing it, I couldn't see the meta.prologue.goyacc scope with the 'Inspect Editor Tokens and Scope' command)

This is currently unpublished, there are instructions below on how to get this in your vscode

To get an installable package file, you'll need vsce. To install it with npm, run:

npm install -g vsce

This will generate goyacc-{VERSION}.vsix:

vsce package

To install the package:

Inside vscode, open the command palette (default ctrl+shift+p) type/run "install from vsix" and choose the generated file
