"""Resolve a site profile's chosen plugins plus their hard-dependency closure.
|
|
|
|
Printed as a comma-separated list, dependencies before dependants, so the caller
|
|
can stage them in order.
|
|
|
|
This lives in its own file because TWO builders need the same answer:
|
|
scripts/build-site.sh (Linux) and deploy/windows/installer/build-installer.ps1
|
|
(Windows). It was inline in build-site.sh; a PowerShell reimplementation would
|
|
have been a second copy of the closure rules, free to drift from this one and
|
|
produce a bundle whose plugin set did not match the profile it was built from.
|
|
|
|
Usage: resolve_plugin_closure.py <site-profile.json> <repo-root>
