# Two jobs, and neither needs a Flutter.
#
# Nothing is built here. The check reads source and no more, so this file needs
# no toolchain at all, which is what keeps it honest about running on every
# push. There used to be a second, scheduled job that re-resolved the
# jolt-native flake input; there is no jolt half any more and no input to
# follow, so there is nothing for a schedule to do.
stages: [check]

# Two toolchains and one artifact between them.
#
# The library is built once, in the image that has Nim, and the Dart job takes
# it rather than installing a second toolchain to rebuild it. That is not only
# tidier: `libfrqcore.so` links OpenSSL and is glibc, so it has to be built
# somewhere its runtime can load it — which is why the Nim job is the Debian
# image and not the Alpine one it used to be. A musl build would not load in
# `dart:*` at all.

# common/ is compiled by ClojureDart for two targets — the APK and the Linux
# desktop — and shared code reaching for the JVM or a `dart:` library breaks
# one of them at a namespace nobody touched. `Math/ceil` in the compose bar was
# the third time. Reading the source is enough to catch it, which is why this
# needs no toolchain and no builder: python and a checkout, a few seconds, on
# every push.
# The Nim core's tests. A second job rather than a step in the first, because
# it wants a compiler where check-common wants nothing: one can fail without
# hiding the other, and the pair of them is still seconds.
# The Nim core: its own suite, and the library the Dart job needs.
#
# `libssl-dev` because `nim/nim.cfg` sets `-d:ssl` — std/net links -lssl and
# -lcrypto for the TLS on :6697, and `frq.atproto` uses httpclient over the
# same. Without it the compile fails on a missing -lcrypto, which reads as
# nothing to do with TLS.
