Hello all,
It is unclear to me what the intended behavior for (include
"filename.scm") is, so I'm sending an email about this potential bug.
The Local Inclusion docs
<https://www.gnu.org/software/guile/manual/html_node/Local-Inclusion.html>
seem to state that relative paths are found relative to the file that
included them.
> If file-name is a relative path, it is searched for relative to the
> path that contains the file that the include form appears in.
So if I have a file "/libraries/libname/main.scm" than has (include
"./helpers.scm"), then the file "/libraries/libname/helpers.scm"
*should* (I think) be imported.
But this does not seem to work if "/libraries" is in the GUILE_LOAD_PATH
and my current working directory is somewhere else, say "/home/user" and
I'm running "/home/user/program.scm" that imports the (libname main)
library from "/libraries". Then Guile seems to try to include the
"libname/helpers.scm" file from the current directory, which does not
exist.
Conversations with leoprikler in IRC have revealed to me that
call-with-include-port is the function responsible for this behavior
<https://git.savannah.gnu.org/cgit/guile.git/tree/module/ice-9/psyntax.scm#n3231>.
`syntax-source` returns a file path relative to the load path, and
include tries to use that path to open a file relative to the current
working directory.
In Guile's bug guidelines
<https://www.gnu.org/software/guile/docs/docs-2.2/guile-ref/Reporting-Bugs.html>,
to me this fits
* Whenever documentation and actual behavior differ, you have certainly
found a bug, either in the documentation or in the program.
and potentially
* When some part of the documentation is not clear and does not make
sense to you even after re-reading the section, it is a bug.
I believe this is a bug, but I may be wrong, so emailing to clarify.
Thank you!

Hi Vijay,
I believe this is the same bug as this one I reported 5-6 years ago:
https://bugs.gnu.org/21613
Sadly there was no progress on it as far as I know.

Thank you Taylan. This does appear to be the same bug. This bug can be
closed as a duplicate. Looks like Andy Wingo suggested a potential fix,
but there was no follow-up. If someone is willing to show me the ropes
when I need them, I can take a stab at learning the Guile codebase and
fixing the bug.

A little nit, but
(include "filename.scm")
is not identical to
(include "./filename.scm")
so might it be worth trying
(include "helpers.scm")
in your code?
And/or should the docs explain that both ways of writing a relative
file name in this context are or are not acceptable?
Might some macro dislike leading dots?
Long shot ;-)

Hello Bengt,
Unfortunately that still doesn't work :( I think they should be
considered the same though, when this bug gets fixed.
