Befunge Support in VS Code

Features

• Implements Syntax Highlighting in VS Code for Befunge-93 and Befunge-98 programming languages.

• Adds alignment guides coming from the directional characters (>, v, <, ^, ?).

Associates .bf, .befunge, and .b93 files with Befunge-93, and .b98 files with Befunge-98.

Installation

1. Open VS Code, select the extensions icon (Windows: ctrl + shift + X, Mac: cmd + shift + X) and search for befunge. Or maybe you are already here in VS Code. Nice!
2. Click install
3. Restart or reload VS Code when prompted
4. Add "befunge.guides.enable": true" to your Workspace or User Settings if you want to enable Befunge alignment guides.
   • note: it is recommended that you also add "editor.renderIndentGuides": false to your workspace settings if you enable this
5. (Optional) add the custom theming described in Extension Settings

Extension Settings

Adds the following new configuration settings:

To get the colors shown in the screenshots, some changes to your User Settings are necessary:

1. Open your user settings (Windows: ctrl + , Mac: cmd + ,)
2. Add the following json to your User Settings (or Workspace Settings to only enable it on your current workspace):

As VS Code does not (yet?) allow themes to be set on a per language basis, this adds to your global theme. However, all scopes used in this blurb end in .befunge, ie, this should not affect your theme anywhere except on Befunge files.

Of course, feel free to modify this to your liking, and look at the scopes contained in the *.tmLanguage.json files to see what other Befunge scopes you can customize the theme for.

Known Issues

• The vertical alignment guides are not centered. I'm sure there must be a way to do this, but if so I haven't been able to think of it!
