Package: Emacs
Version: 27.0.50
We should provide some `current-source-file-name` function which macros
can use to find get the name of the source file in which they were invoked.
Currently, some packages use a mix of load-file-name and
byte-compile-current-file to get that information, but it's hackish.
It'll be difficult to implement `current-source-file-name` in a way that
works reliably in all cases, but at least by providing this function we
can isolate the hack in a single place (and hope to refine it over time,
e.g. by tweaking bytecomp.el and lread.c so as to provide *better*
underlying information).
Along the same lines, it'd be great to provide
`current-source-definition-name` or even `current-source-line-number`.

FWIW, I've used (or load-file-name (buffer-file-name)) in a couple of
packages, and that's worked well for my purposes.

Obviously, it won't work if you need it during macro expansion.

`f-this-file' from the `f' package is some prior art, but I guess it also
doesn't work correctly with macros.

emacs-load-relative uses the name "__FILE__" for the same thing.

Emacs's `master` now has the `macroexp-file-name` function which
provides this functionality. So I guess `emacs-load-relative` could now
redefine __FILE__ as
(defmacro __FILE__ () (macroexp-file-name))
tho oddly it seems that it defines `__FILE__` as a function rather than
a macro, so maybe it should be
(defalias '__FILE__ #'macroexp-file-name)
but that doesn't match the semantics I expect from something called
`__FILE__`.
In any case, my original request is now satisfied, so I'm closing this.
