- hooks load the _stack files of every directory between the stack path root
and the stack, outermost first: make included both $(dir)/*.mk and
$(dir)/*/*.mk, so a stack in a subdirectory saw its parent's settings
- a group may be declared in <group>/<group>.env, where the stack lives
- MYOS_STACK_DIR lets a hook read a file it ships next to itself
- myos_filter no longer confuses a literal * in a make pattern with a wildcard,
and the list helpers no longer let the shell expand a * into filenames
- MACHINE, SYSTEM, HOST and DOMAINNAME join the framework variables a hook sees
- the make shim gains $(call myos-var,NAME), so a .mk target can read a
setting that now lives in a hook, and it picks up the .mk of every stack
directory rather than only the project's
myos build up logs host/fabio runs the three in order and stops at the first
failure, the way make build up logs STACK=host/fabio did. Leading words that
name commands are commands; the first word that is not one starts the stacks.
A stack found in several directories of the stack path is now merged rather
than shadowed, least specific first, so a project drops
stack/postgres/postgres.local.yml next to the catalogue's postgres.yml and
refines it. Settings hooks follow the same order, so a project can redefine a
default the catalogue ships. Neither engine did this before: the project
directory simply hid the catalogue one.
An unknown command now says so and suggests the command to type, instead of
printing the whole usage.
An install under a custom prefix (--prefix ~/.local) could not find the
catalogue it had just cloned into <prefix>/share/myos: only the three system
paths were searched.
holcommon's empty .env made the loader evaluate one blank line, which
tripped set -u. Verified afterwards on holcommon's real host stack: the CLI
and the make engine resolve the same five files and render a byte-identical
241-line compose config.
A stack is a directory of compose files; the current directory is a stack when
it holds one. The same command works for a project, a catalogue stack, a group
and a host singleton, and stacks sharing a project are now a single compose
call.
Two traps of the make engine are closed on the way: an unknown command is an
error instead of a silent success, and a group is only expanded when its name
is lowercase, so an environment variable can no longer be mistaken for one.
That guard spells out its character class because a-z matches uppercase too
under a dictionary collation.
Replaces the 500-character stack_path expression of
make/apps/def.docker.mk:159 and its leaked $(stackz) loop variable with
three readable functions, covered by 20 assertions.
