bakar diff

Compare two versions of a manifest or kas config and report per-layer SHA changes.

Synopsis

bakar diff OLD NEW [OPTIONS]

Arguments

Argument Description
OLD Old manifest XML (NXP) or kas config (BYO/bbsetup)
NEW New manifest XML (NXP) or kas config (BYO/bbsetup)

Options

Flag Short Description
--manifest -f Manifest filename for BSP family dispatch
--workspace -w Workspace root override

Examples

# Compare two NXP manifest versions
bakar diff imx-6.6.52-2.2.0.xml imx-6.12.49-2.2.0.xml

# Compare with a pinned manifest (see what changed since pinning)
bakar diff pinned-manifest.xml imx-6.12.49-2.2.0.xml

# Compare two kas config files (delegates to kas diff / kas-container diff)
bakar diff kas-old.yml kas-new.yml

Output (NXP manifest diff)

meta-imx         abc12345  def67890  +23  changed
meta-variscite   11223344  11223344       unchanged
poky             99aabbcc  00112233  +8   changed

Columns: layer name, old SHA (8 chars), new SHA (8 chars), commit count ahead (+N if resolvable), change marker.

Notes

  • When both arguments are .xml files, bakar parses the manifests and diffs layer SHAs directly. The commit count requires the layer repos to be checked out under sources/.
  • For non-.xml files, bakar delegates to kas diff (or kas-container diff outside host mode) and passes the exit code through.
