Random testsuite failures
I'm not sure how to reproduce this but i ran opam install -t bogue in a controlled debian docker environment twice in the span of a couple days and one succeeded but the other failed with:

Hi when bogue does not find its share directory, it tries to download it from the internet, using wget, which fails here because wget is not found on the system.
what I don't understand is that this mechanism was designed for standalone applications made by bogue but not accompanied by the bogue library. In principle, when installing bogue as a library with opam, the share dir is automatically installed in the appropriate .opam/ subdir

in that case i'm not sure why the testsuite ever worked in opam given installation is always done after the tests. Is there no fallback other than downloading it? (which is forbidden by the sandbox)
I never really understood how opam and or dune installed assets, but yes running any bogue app requires some files (icons, font, etc.) to be installed in a reachable place. For reading, bogue tries many places (local dir, .opam dir, .config dir, app dir) but I'm not sure what is the correct way to save the files for the test suites
Here is a copy of the logs of the CI: https://ocaml.ci.dev/github/sanette/bogue/commit/575404de51963d62d4729a1296468ef8e607a38d/variant/debian-12-5.2_opam-2.2 Somehow there the assets in the _build directory can be found. I wonder why this was not the case for you
/src: (run (shell "opam exec -- dune build @install @check @runtest && rm -rf _build"))

is there a missing dependency toward that asset? If there is no dependency then the availability of that directory will be dependent on the machine (depending on the number of core and which task finished first)
is there a missing dependency toward that asset?
probably not... what is the way to do this? EDIT: I mean that probably I didn't write the dependency explicitly
what is the way to do this?
using (deps ...): https://dune.readthedocs.io/en/stable/reference/dune/rule.html#rule
ok so I suppose that in the file examples/dune
we should add
(deps "share/bogue/themes/default/bogue.conf")
is this the correct path prefix to indicate?
well, I need to read more...
$ dune runtest
Error: No rule found for examples/share/bogue/themes/default/bogue.conf
-> required by alias examples/runtest in examples/dune:10
will try to think about it when I have more time. thanks for reporting!
is this the correct path prefix to indicate?
probably not. That would ../<that path>, otherwise it would be the share/ directory inside examples/
also you probably want (deps (file ...)) or (deps (source_tree ...)). See https://dune.readthedocs.io/en/stable/concepts/dependency-spec.html
