Allow \n to trigger a softwrap

[rfon6ngy]

ref: #231118 (2024) + #89120 (2020)

Goal

This PR add soft-wrapping on literal \n in addition to viewport and column based limitation when editor.wrapOnEscapedLineFeeds is enabled.

So this JSON declaration

would be shown as

previous failed attempts:

There are currently no extension There are currently no extension API that would allow a language-specific extension to hint the editor into soft-wrapping at specific offset. So I create a test extension that would inject `
` and `\n` in the editor view (using `InlayHints` and `createTextEditorDecorationType`) but none of them worked and were rendered inline

So the only way was to add the wrapping detection in the createLineBreaks method of the MonospaceLineBreaksComputerFactory

I'm open to discussions about:

• hide this behavior behind a possible wordWrapOnLiteral boolean EditorOption
• Providing a wrapping API for VSCode extension instead (would allow a language-specific decision) =>this is way above my skills

Nice idea! Could you please implement this behind a setting, maybe something like editor.wrapOnEscapedLineFeeds or maybe you have a better idea for a name.

Hi @alexdima sorry for the delay. I'm on holiday today so yeah I've hidden the feature behind a editor.wrapOnEscapedLineFeeds flag.

See for yourself: default config

with editor.wrapOnEscapedLineFeeds set to true

@microsoft-github-policy-service agree

@alexdima do you need anything else ?

Seems like I'm not the first one with this idea...
