v3.4.0

Additions

• Asynchronous expressions are now supported!
  • parseAsync returns an async function

    const expr = jshiki.parseAsync('1 + 2')
    await expr() // => 3

  • evaluateAsync returns a promise

    await jshiki.evaluateAsync('1 + 2') // => 3

  • await is supported within async expressions

    const expr = jshiki.parseAsync('await a()')
    await expr({ a: async () => 1 }) // => 1

Fixes

• Fixed bug where calling a method on a property using optional chaining syntax would instead operate as though regular member access was used. Example:

  // Prior behavior:
  jshiki.evaluate('a?.b?.()') // throws TypeError
  jshiki.evaluate('a?.b()') // throws TypeError
  
  // Patched behaviour:
  jshiki.evaluate('a?.b?.()') // returns undefined
  jshiki.evaluate('a?.b()') // returns undefined

Development changes

• Unit tests are now run before functional tests.
• Updated yarn to 3.0.2
