Flows

Format

FBL expecting flows to be presented as YAML files with following format:

# [optional] flow version, used for informational purposes only.
version: 1.0.0
# [optional] flow description, used for informational purposes only.
description: |-
Plugn invoker.
# [optional] flow runtime dependencies
requires:
# [optional] fbl version requirements
fbl: '>=1.1.0'
# [optional] required plugins and their versions
plugins:
'@fbl-plugins/http': '>=0.1.0'
# [optional] required native applications presented in the PATH environment variable
applications:
- echo
# [required] entry point
pipeline:
# Pipeline may only have one root action ID (or alias).
# Value format is specific to the action. Each action may have its own format and requirements.
exec:
command: echo
args:
- 'Hello World'
# Metadata field.
# Each action may have zero or more additional metadata fields associated with it.
# All metadata fields should start with dollar sign ($).
$title: 'Say hello'

In most cases you will use flow control action handlers as a starting point of your flow.
