"""Import/export formats plugin — provides standard file formats as plugins.
|
||
|
|
|
||
|
|
Part of the W4a contribution architecture (Spec #359): file formats live in
|
||
|
|
this plugin instead of being hardcoded in the core orchestrator. New formats
|
||
|
|
(e.g. PDF later) are added as additional format plugins without touching the
|
||
|
|
core.
|
||
|
|
|
||
|
|
Lifecycle: registers the bundled handlers (csv, json, xlsx) in the core
|
||
|
|
format registry on activate, unregisters them on deactivate.
