I only really understand half of it without getting my fingers on it, but sounds like some good stuff.
The
path::absolute()that's hidden in the stabilized items is definitely something I've wanted for a while, though.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?
False
I'll assume you meant
.., since...is an ordinary filename. (Aside from the "who remembers ...?" feature introduced in Windows 95'sCOMMAND.COMwherecd ...was shorthand for doingcd ..twice and you could omit the space aftercdif 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/fooand 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.
Huh that might actually be an issue with your client, mine renders those as two dots
I'm using the web UI, so I'm assuming whatever broad-spectrum Markdown rendering library it uses has smart quote rendering turned on.
