monaco-editor tokenizer do not support "ignore case" regex

Question

The tokenizer in monaco-editor do not seem to support 'ignore case' i flag in regex. Sample code below,

To replicate, you can paste this in playground and try running yourself.

monaco.languages.register({ id: 'sample' });
monaco.languages.setMonarchTokensProvider('sample', {
    tokenizer: {
        root: [
            [/cmd1|cmd2/i, 'keyword']
        ]
    }
});

monaco.editor.create(document.getElementById('container'), {
    value: "cmd1 10\nCMD2 10",
    language: 'sample'
});

cmd1 turns blue while CMD2 do not.

Is this intentional? Is there a way around?

Answer 1

Adding ignoreCase:true to the options should work.
