A submodule with only a .git pointer looks non-empty to ls -A, so the self-heal skipped every un-checked-out nested submodule. Check for real worktree content instead (find excluding .git).

# Recursive submodule init for the rexglue SDK with self-healing for broken
|
|
# upstream pins.
|
|
#
|
|
# The rexglue fork pins several nested third-party submodules (imgui, ...) to
|
|
# commits their upstreams no longer carry, so a plain
|
|
# `git submodule update --init --recursive` aborts at the first broken pin
|
|
# and leaves every later nested submodule empty (a fresh clone cannot build).
|
|
# For each nested submodule still left empty, this script fetches its origin
|
|
# and checks out the default-branch tip, which is enough to build.
|
|
#
|
|
# Run from the repository root after `git submodule update --init` (top
|
|
# level). No-op when everything initialized fine.
