[Feature] File preview

[TimerWolf]

Feature Description

When you use the web interface, why is it not possible to have preview of a new file that is created in the repository?

You can do it with already created files that you edit but not with new files and i find this very strange, it would be very useful for lets say is you create a new "markdown" file.

Repository -> Add File -> New File

But the preview tab is missing

Preview Tab should be there for at least markdown, but I do agree we could show it for other file types as well, if there is a benefit.

Also see #23333 which touches these parts.

The Preview tab is not there for New File at all, only for Edit File. Editing a .txt file and renaming it to .md also does not make a Preview tab appear.

I had a quick look, and there seem to be two things to fix:

• Make the preview tab visible for IsNewFile in templates/repo/editor/edit.tmpl
• Run the previewable file extensions detection in createCodeEditor after editing the file name, not only on page load.

I won't have time to submit a proper fix in the next few days, anyone feel free to take over. Otherwise I'll get to it later.

I agree, we should try to handle new file similar to edit file.
