# Apply the Eclipse formatter (dev/CodeStyle_eclipse.xml) to ONLY the lines you
# edited -- the exact scope the "Java Format" CI check enforces.
#
# A bare `mvn formatter:format` would reformat EVERY .java file under the source
# roots, and even scoping to changed *files* would reformat their pre-existing
# (not-yet-clean) lines. The existing tree is not fully formatter-clean, so both
# would produce a large unrelated diff. This delegates to dev/format_changed.py,
# which formats each changed file but keeps only the changes that land on the
# lines you actually edited.
#
# "Changed" = lines that differ from the base branch (the merge target),
# including your committed-on-branch, staged, unstaged and untracked edits. Run
# `git fetch upstream main` first so the diff is accurate, or pass an explicit,
# current base ref if the default is stale/behind your branch point. The base-ref
# fallback order lives in one place: see resolve_base() in dev/format_changed.py.
#
# Usage:
#   dev/format-changed.sh [base-ref]
#     base-ref  branch/commit to diff against (default: resolved by
#               dev/format_changed.py)
