Execution flow can be presented in different output formats. FBL supports only 2 generic ones: json and yaml. All other reporters should be provided as 3rd-party plugins.
fbl \-o /tmp/fbl.json \-r json \sample.flow.yml
fbl \-o /tmp/fbl.yml \-r yaml \sample.flow.yml
3rd Party Reporter options:
fbl \-o /tmp/fbl.3rd \-r 3rd.party \--report-option key=value \sample.flow.yml
