Getting errors from Monaco editor

Question

I would like to get hold of the errors created by default by Monaco editor.

Answer 1

看起来您可以调用monaco.editor.getModelMarkers({})来获取文档中所有标记的列表，然后自己过滤以将其限制为您感兴趣的错误。我更喜欢更清楚的-记录的路线，但在我的临时测试中这是有效的。

Answer 2

Given a monaco model, you can have access to the worker. This is similar to a ts.LanguageService but the signatures are async. With that you can then call getSemanticDiagnostics() and all the rest.

monaco.languages.typescript.getTypeScriptWorker()
  .then(_worker=>{_worker(model.uri)
  .then(worker=>{

    worker.getScriptFileNames().then(ff=>{
      ff.forEach(sf=>{
        worker.getSemanticDiagnostics(sf).then(dd=>{          
          console.log('\n\n DIAGNOSTICS FOR '+sf)
          console.log(dd.map(d=>d.messageText))})
        })

Answer 3

This is a simple sample to log errors:

import * as monaco from 'monaco-editor'

// ...

monaco.editor.onDidChangeMarkers(([uri]) => {
  const markers = monaco.editor.getModelMarkers({resource: uri})
  console.log('markers:', markers.map(
    ({ message, startLineNumber, startColumn, endLineNumber, endColumn }) =>
      `${message} [${startLineNumber}:${startColumn}-${endLineNumber}:${endColumn}]`,
  ))
})
