What is the process for integrating a new token into an established programming language, such as TypeScript?

Utilizing setMonarchTokensProvider allows me to define tokens, but it has limitations. I am able to create a new language or override existing typescript, however, this does not provide me with access to the rest of the typescript tokens that I still require.

My goal is to introduce a single token that holds significance within the context of this editor and can be colorized, while retaining all typescript functionality.

The code snippet below is what I currently have (adapted from playground examples), but it eliminates the other typescript tokens:

monaco.languages.setMonarchTokensProvider('typescript', {
    tokenizer: {
        root: [
            [/\pvm.*/, "custom-error"]
        ]
    }
});


monaco.editor.defineTheme('myCoolTheme', {
    base: 'vs',
    inherit: true,
    rules: [
        { token: 'custom-error', foreground: 'ff0000', fontStyle: 'bold' }
    ]
});

(After implementing the myCoolTheme when initializing the editor)

Answer №1

After some searching, I managed to locate the .js file for the language and made the necessary customization directly there. It may not have been my preferred method, but at least it got the job done.
