• Snippets for simple loops and grammars
• Language Server providing:
  • Syntax checking and warnings

Other recommended settings

I also recommend the following vscode settings when using Raku. The word separators are important for highlighting function names that have a hyphen in them, and for variables that include sigils.

"[raku]": {
    "editor.wordSeparators": "`~!#^&*()=+[{]}\\|;:'\",.<>/?",
},

Configuration Settings

• raku.rakuPath specifies the location of your raku install. Defaults to "raku"
• raku.includePaths adds locations to the path via a -I command line switch
