This also fixes a few test installers:
- rustfmt is available via apt-get in 22.04, use that instead of tarball
that's no longer available
- brittany now installs cleanly in the default haskell ghc/cabal in
22.04, so just use that
- perltidy in 22.04 has slightly different output
- nixfmt download url changed (now includes OS/arch). There was
initially no binary available when nixfmt was updated,
but the devs there were kind enough to provide one:
https://github.com/serokell/nixfmt/issues/139
This runs a full `make fmt-build` without errors, though it takes a
while ;). All tests pass, too.
* Fix brittany installation, needed the `--reorder-goals` argument to be
added so that a version that was not the latest version could be
installed so that it was compatible with the base lib version shipped
with Ubuntu 20.04. We'll upgrade to 22.04 eventually (before it falls
out of LTS). Ref: https://github.com/radian-software/apheleia/pull/221
* Add a `make fmt-build-common` target which allows tagging a docker
image containing just the base software and not any formatters, to make
it easy to debug formatter installation manually.
* Update `apheleia-ft` to also run formatter tests when any files
affecting a formatter are changed, which includes the installation
script, the sample input/output, and also any scripts (e.g.
`apheleia-phpcs`) that it uses. We don't have any logic that will run
all formatter tests at once, because that is unwieldy. That can be done
manually if making a big change.
* Update to actions/checkout@v4 from v2 because the older one was listed
as deprecated.
* Print full stacktraces when `apheleia-ft` fails with an Elisp error.
