Color Scheme for VS Code

When I was developing a prompt plugin for the icon font component, I wanted the color of the prompt icon to change according to the current color scheme to improve readability.

At first, the API documentation for VS Code extensions was not clear to me, and I couldn’t find relevant APIs.

Then I came across a method on antfu’s blog:

Since most of the themes follow the conversions of having Light or Dark in their names. Then we can have:

import { workspace } from 'vscode'

export function isDarkTheme() {
  const theme = workspace.getConfiguration()
    .get('workbench.colorTheme', '')

  // must be dark
  if (theme.match(/dark|black/i) != null)
    return true

  // must be light
  if (theme.match(/light/i) != null)
    return false

  // IDK, maybe dark
  return true
}

This method was effective, but still somewhat awkward😣. So I continued my search and finally found in a VS Code issue that we can get the current color scheme like this:

import { window } from 'vscode'

export function isDarkTheme() {
  const { kind } = window.activeColorTheme
  if (kind === 2 || kind === 3)
    return true
  else
    return false
}
