Oh, alright then. Patch applied (#3494)
Thanks. One more patch for your consideration for something I needed
recently: getting absolute, canonical file paths. In principle this
can be implemented in pure Lua with the current lfs module, but
getting all the corner cases right (e.g. foo/bar/./../baz) is not so
easy. Perhaps having a convenience function for this is not such a bad
idea (and using proper system APIs will guarantee that the result is
correct).
There is no Unix counterpart in the patch, because I didn't know how
to implement it (with a call to realpath?) and I would have no way to
test it anyway.
My man page for realpath(3) says:
BUGS:
Avoid using this function. Its is broken by design
But it does not offer an alternate solution.
Looks like it would need private code, which is not a lot of fun to
write (unless there is something in kpathsea?).
