Transforming paths in compilation output (containerized builds)

["Björn Bidar" <bjorn.bidar@thaodan.de>]

Hello,

I'm looking how to transform the output in the compilation buffer or
just make Emacs open the correct paths inside builds happen inside
containerized builds.

The output of the programs ran inside these environments relates
to the environment they are build in e.g. container in
/var/tmp/build-root/<name> and output as if /var/tmp/build-root/<name>
is /.

I'm having this situation when building with osc build which sets up a
linux environment generated according to the settings of the repository,
e.g. a Debian system debbuild or openSUSE system with rpmbuild with
the dependencies required to build a package. For context osc is the
commandline client to the Open Build Service also known as openSUSE build service.

The builds can be inside a change root, a container or a vm.

The second example would be builds in Scratchbox2, a cross compiling
environment.
There the paths are also relative to the environment, a Scratchbox2
target or if they don't exist in the target simply relative to the host.

E.g. /usr/include/foo.h -> target
~/project/foo.c -> host

I did some research, I found other modes such as ppcompile which uses
compilation-finish-functions.
For remote environments I know that tramp uses file-name-handler-alist.
Is it possible to register temporary file-name handler for this context
or are there better methods to achieve what I want to do?

Have a great weekend,

Björn
