# push-split.sh — push a subdirectory of the monorepo working-copy to its
|
||
|
|
# matching split repo on Hephaestus, preserving history via git-subtree-split.
|
||
|
|
#
|
||
|
|
# Since silentmode/silentmode was deleted and each project lives in its own
|
||
|
|
# repo on the forge (silentmode/theseus, silentmode/ariadne, silentmode/hephaestus,
|
||
|
|
# silentmode/sirius, …), cross-cutting commits made in this working copy need to
|
||
|
|
# be routed to whichever remote corresponds to the touched project.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# scripts/push-split.sh <project-dir> [remote-name]
|
||
|
|
#
|
||
|
|
# Examples:
|
||
|
|
# scripts/push-split.sh Hephaestus # → git remote 'hephaestus'
|
||
|
|
# scripts/push-split.sh TheseusNavigator # → git remote 'theseus' (Navigator suffix stripped)
|
||
|
|
# scripts/push-split.sh AriadneResolver # → git remote 'ariadne' (Resolver suffix stripped)
|
||
|
|
# scripts/push-split.sh site-sirius-x sirius # → remote 'sirius' (explicit override)
|
||
|
|
#
|
||
|
|
# List of configured remotes: `git remote -v`
|
||
|
|
#
|
||
|
|
# Notes:
|
||
|
|
# - Only ONE prefix per invocation. Cross-cutting changes that touched multiple
|
||
|
|
# projects need to be run once per touched directory.
|
||
|
|
# - Uses --branch <ephemeral>, pushes, then deletes it. Nothing sticks around.
|
||
|
|
# - Push target is always <remote>:master. Passing --branch was intentional
|
||
|
|
# over --squash: split history is preserved so file blame on the split repo
|
||
|
|
# still points at the real commits.
