26.3; Doc of functions that accept file-name args: say whether absolute |
Date: |
Mon, 6 Dec 2021 22:26:46 +0000 |
This report is about the doc strings and the doc in the Elisp manual for
functions that accept file-name args.
Please say, somewhere (preferably in each relevant node, since someone
might not start reading in node `Information about Files'), about the
file-name arg for a function documented in the node, whether the name
must be absolute or relative (e.g. to `default-directory') or can be
either. Similarly, for the doc strings of such functions.
E.g. function `file-exists-p' itself expands its arg relative to
`default-directory', if the arg isn't an absolute name. This isn't
obvious.

It should be obvious, because anything else would be a terrible bug,
as should be clear if you consider the alternatives. Which is why
Emacs does that in _all_ APIs that accept file names.
Closing.
