Welcome to your VS Code Extension

What's in the folder

This folder contains all of the files necessary for your extension.
package.json - this is the manifest file in which you declare your language support and define the location of the grammar file that has been copied into your extension.
syntaxes/ll.tmLanguage.json - this is the Text mate grammar file that is used for tokenization.
language-configuration.json - this is the language configuration, defining the tokens that are used for comments and brackets.

Make sure the language configuration settings in language-configuration.json are accurate.
Press F5 to open a new window with your extension loaded.
Create a new file with a file name suffix matching your language.
Verify that syntax highlighting works and that the language configuration settings are working.

You can relaunch the extension from the debug toolbar after making changes to the files listed above.
You can also reload (Ctrl+R or Cmd+R on Mac) the VS Code window with your extension to load your changes.
