An extra space is added after three backticks when switching from WYSIWYG to Markdown

[yihui]

Version

1.1.0

Test Environment

Google Chrome on macOS, with the example https://nhnent.github.io/tui.editor/api/latest/tutorial-example01-basic.html

Current Behavior

Add a code block to the editor:

```js
var x = 1;
```

Switch to the WYSIWYG mode, then switch back the Markdown mode. An extra space is inserted bewteen the three backticks and js:

``` js
var x = 1;

```

And note that a blank line is also added before the closing fence (the last three backticks), which is also unnecessary.

Expected Behavior

No spaces after the three backticks.

@yihui Sorry for late reply. This issue does not occur in the latest version so close it.

[yihui]

No worries. Thank you!

BTW, I guess the documentation website still uses an old version, since the issue is currently still reproducible at https://nhnent.github.io/tui.editor/api/latest/tutorial-example01-basic.html.

@yihui I just reproduced that a blank line is added before the closing backticks. Currently it does not occur but issue that an extra space is inserted before js occur in the latest version. But I think it is not important bug so I will consider this issue after resolved other important issues.

This issue seems to be resolved. Currently I can't reproduce. So close the issue. If you can reproduce it, I'd like to upload a screenshot with gif.

[yihui]

It is still reproducible, at least on this page: https://ui.toast.com/tui-editor/ (Click "All Extensions")

Markdown mode

Switch to WYSIWYG mode

Switch back to Markdown mode

Now you see the extra space:

@yihui
I understand the issue you said. First, I don't know exactly why the space was added between the code block syntax(three backticks) and the language name. By the way, this syntax is not a bug because it does not violate CommonMark specification.

Okay. Thank you very much anyway!
