    I’m not really sure I get the usefulness of this absolute function. It still returns relative paths if the input was relative and it doesn’t resolve “…”. What would you use it for where canonicalize doesn’t work for you?

      Well, as it says in the documentation I linked:

      unlike canonicalize absolute does not resolve symlinks and may succeed even if the path does not exist.

      Primarily, the latter part is what I want. There’s just sometimes situations where a path doesn’t exist (yet), but you want to know what it would look like as an absolute path.

      False

      and it doesn’t resolve “…”

      I’ll assume you meant .., since ... is an ordinary filename. (Aside from the “who remembers …?” feature introduced in Windows 95’s COMMAND.COM where cd ... was shorthand for doing cd .. twice and you could omit the space after cd if your target was all dots.)

      The reason it doesn’t do that is that, when symlinks get involved, /foo/bar/.. does not necessarily resolve to /foo and making that assumption could introduce a lurking security vulnerability in programs which use it.

        Hm it seems I misread the documentation there. I know why it doesn’t resolve the “…” and that’s fine, it just seemed very unnecessary in combination with my flawed understanding of the relative path handling.

        Edit: and just to be snarky: I didn’t type “…” I typed “…”. ;)

          *chuckle* I think Lemmy typed those for you, because I typed three periods and got a Unicode ellipsis, and both of those are also unicode ellipses.

              I’m using the web UI, so I’m assuming whatever broad-spectrum Markdown rendering library it uses has smart quote rendering turned on.
