The Problem:
I am developing a code editor using Monaco and want to customize the theme to highlight specific parts of code differently. I want variables to be highlighted in light blue, types in dark green, and functions in yellow, but the default ‘vs-dark’ theme uses different colors. How can I achieve this customization?
The Solutions:
Solution 1: Use custom theme and rules
Yes, it is partially possible. Here’s a solution:
1. Define a custom theme inheriting from `vs-dark` and add rules to customize specific tokens. Here is an example theme definition:
“`
monaco.editor.defineTheme(‘default’, {
base: ‘vs-dark’,
inherit: true,
rules: [
{ token: ‘identifier’, foreground: ‘#9CDCFE’ },
{ token: ‘type’, foreground: ‘#1AAFB0’ },
],
colors: {}
});
2. Set the custom theme using `monaco.editor.setTheme()`.
“`
