git subsystems-split [OPTIONS]
|
||
|
|
|
||
|
|
Ardupilot's git extension.
|
||
|
|
|
||
|
|
Split HEAD commit into commits separated by subsystems (vehicles, libraries and
|
||
|
|
folders in the project's root). Basically, reset and call commit-subsystems.
|
||
|
|
|
||
|
|
If neither --copy or --edit is passed, then subsystems-split will try to make
|
||
|
|
the original commit's message into a template for commit-subsystems.
|
||
|
|
|
||
|
|
Options:
|
||
|
|
--copy
|
||
|
|
Make all commits have exactly the same message as the HEAD commit.
|
||
|
|
|
||
|
|
--edit
|
||
|
|
Edit the commit message as a template for commit-subsystems.
