Support text/plain mode?

[Gaz83]

Any chance to support text/plain mode?

[gaelj]

In the demo you can view the raw test by unchecking this box

This sets the component's AutoFormatMarkdown parameter accordingly.

If that's not what you have in mind, could you elaborate ?

[gaelj]

OK I think I understood : you want plain text as a language option ?

[Gaz83]

Yeah if possible. In CodeMirror5 you can set the mode to null or plain/text. Not sure if CodeMirror6 has similar.

Looking at what you wrote I am now thinking set language to Markdown, switch off the autoformat and disable highlighting. This should do the same thing? If so, wonder if you can change so that you can select plain text and it sets those options for you.

Implemented and deployed ; can you check and either close this issue or comment it ?

Got the following exception

index-C6LAOLAl.js:77011 Error in initializing CodeMirror TypeError: Cannot read properties of null (reading 'extension') at inner (index-C6LAOLAl.js:2038:31) at inner (index-C6LAOLAl.js:2022:13) at inner (index-C6LAOLAl.js:2015:17) at flatten (index-C6LAOLAl.js:2044:5) at Configuration.resolve (index-C6LAOLAl.js:1952:25) at EditorState.create (index-C6LAOLAl.js:2783:43) at Module.initCodeMirror (index-C6LAOLAl.js:76986:45)

That was from console in Edge

In my blazor app I get this

An error occurred while loading the editor: Message: Cannot read properties of undefined (reading 'state') TypeError: Cannot read properties of undefined (reading 'state') at Module.setDoc (https://localhost:7214/_content/CodeMirror6/index-C6LAOLAl.js:77132:46) at https://localhost:7214/_framework/blazor.web.js:1:3244 at new Promise (<anonymous>) at y.beginInvokeJSFromDotNet (https://localhost:7214/_framework/blazor.web.js:1:3201) at fn._invokeClientMethod (https://localhost:7214/_framework/blazor.web.js:1:62869) at fn._processIncomingData (https://localhost:7214/_framework/blazor.web.js:1:60344) at connection.onreceive (https://localhost:7214/_framework/blazor.web.js:1:53985) at i.onmessage (https://localhost:7214/_framework/blazor.web.js:1:82130)

Can you make sure the browser cache is cleaned ?

[Gaz83]

Just tried again with cache cleared, still the same.

[gaelj]

Are you running the example locally or are you on the github actions demo ?

If locally, try running dotnet clean and dotnet build in the CodeMirror6 project .

[Gaz83]

I am running it all locally. Cloned the git, referenced the project and using in my own projects. I am now going to use your examples project locally. Will get back in a few moments

[Gaz83]

Ok I can confirm your Examples.BlazorServer projects works fine locally. Let me investigate my projects to see what is happening.

In the mean time, would it be possible to make the nuget packaging? or put it near the top of the list? I think you have good project here and it would be worth doing.

[Gaz83]

Ok I have managed to replicate the issue locally in your examples. Go into Example.razor and change the Language from the default CodeMirrorLanguage.Markdown to CodeMirrorLanguage.PlainText so that it starts up with that language set. Now when I run it I get the same errors. If I leave it as Markdown and change it to PlainText through the browser then it works fine.

And just as a test, I tried CSharp as the default and that works, so seems related to PlainText at startup

[Gaz83]

I also just done this in my own project to confirm it's the initial setting. This works.

protected override Task OnAfterRenderAsync(bool firstRender)
  {
      if (_codeMirror is not null)
          if (_codeMirror.Language != CodeMirrorLanguage.PlainText)
                  _codeMirror.Language = CodeMirrorLanguage.PlainText;

      return base.OnAfterRenderAsync(firstRender);
 }

[gaelj]

The bug is now fixed. Thanks for pointing it out !

[Gaz83]

I can confirm the issue is resolved. Tested and now using the nuget package :-D
