[bug#35653] [PATCH] gnu: Add rcm.

[Josh Holland <josh@inv.alid.pw>]

Hi,

Below is the first package definition I have written for Guix, defining
the dotfile management suite rcm[0].  I'm sure there are changes to be
made before it can be merged, and I did have a few issues while I was
writing it.  However, it does now build, install and run fine on my
local machine.

First, I wasn't sure whether it fits into an existing module already.
I had a look through the contents of gnu/packages/ but I didn't see
anything that really stuck out.  Perhaps it fits into shellutils?

Second, I had a lot of trouble with the test suite.  The first thing
that I had to solve was some hardcoded paths in the test cases, which
I solved with the following argument to `#:phases`:

(modify-phases %standard-phases
  (add-after 'patch-source-shebangs 'patch-tests
    (lambda _
      (substitute* '("test/rcrc-tilde.t"
                     "test/rcdn-hooks-run-in-order.t"
                     "test/rcup-hooks-run-in-order.t")
        (("/bin/sh") (which "sh")))
      (substitute* "test/rcup-hooks.t"
        (("/usr/bin/env") (which "env")))
      #t)))

This may or may not be the right way to go about things; I'd appreciate
some feedback on that.

However, I was still having issues with certain tests
(`test/rcup-hooks.t`, `test/rcdn-hooks.t` and possibly others)
non-deterministically failing trying to create and read /tmp/test files.
I'm not sure how to fix this, or even what's causing it: every time I
tried to reproduce it by hand the tests passed.  I assume that something
is deleting /tmp/test while the test is running but I'm not sure what.
In the end I just disabled the tests, since even passing XFAIL_TESTS
doesn't work as sometimes the tests just pass.

If there are any ideas to solve the tests, or any other issues that need
fixing, I'm happy to re-submit the patch.

Thanks,
Josh

+or “dotfiles” because they begin with a period.  This suite is useful
+for committing your rc files to a central repository to share, but it also
+scales to a more complex situation such as multiple source directories
+shared between computers with some host-specific or task-specific files.")
