Link github wiki to trunk code

Question

In an Github wiki it is possible to embed code. Is it possible to link to source code via a filename (and line number?) from within the wiki's repo?

Ideally there would also be some type of error displayed if the referenced file was later deleted.

I looked at these issues, but they do not cover it:

Linking to other Wiki pages on GitHub?

GitHub link from Issue to Wiki

Answer 1

The wiki markdown-cheatsheet does show a link to a source file (in a wiki page).

You can use a simple http link, which means you can reference any file, with line number directly in that url.

Or you can use a relative path

[I'm a relative reference to a repository file](../blob/master/LICENSE)

But in that last case, the line numbers might not work.
