3. Acting on every project

exec runs a command in every project, in release order, and sums up:

$ fobis ecosystem exec -- git log --oneline -1

==> core: git log --oneline -1
c3b0b47 feat(core): add halve()

==> mathx: git log --oneline -1
fae4cf3 docs: explain quadruple()

==> app: git log --oneline -1
48ded4b feat(app): first release

Project  Result        Time  Detail
core     passed        0.0s
mathx    passed        0.0s
app      passed        0.0s

3 passed, 0 failed

--only core,mathx restricts it, --from mathx resumes after a failure, --fail-fast stops at the first one. Any command works, FoBiS's included:

$ fobis ecosystem exec -- fobis build --quiet

==> core: fobis build --quiet

Following the dependencies

fetch runs fobis fetch --update in every project with dependencies, in release order, so a project is updated after what it uses:

$ fobis ecosystem fetch

==> mathx: fobis fetch --update
Updating core
Saved deps config to third_party/.deps_config.ini
Saved lock file to third_party/fobos.lock

==> app: fobis fetch --update
Updating mathx
Updating core
Saved deps config to third_party/.deps_config.ini
Saved lock file to third_party/fobos.lock

Project  Result        Time  Detail
core     skipped             no dependencies
mathx    passed        0.2s
app      passed        0.2s

2 passed, 0 failed

What you learned

fobis ecosystem exec -- COMMAND with --only, --from, --fail-fast; fobis ecosystem fetch.
