Templating

Updated at November 18, 2024
For the YaWL specification fields that support templating, values can be generated dynamically using the data obtained from the workflow state. The templating language is jq. For more information, see the jq documentation.
By default, templating is not used for string values of fields; use string interpolation instead.
Input data for the templater
The templater input data will be different depending on the field.
| Field | Payload |
|---|---|
input |
Overall state of the workflow |
output |
Step output data |
| Other fields that do not support templating | JSON object filtered by input |
Examples
| Field value | Templater interpretation |
|---|---|
this is just string |
Non-templated string |
this is value from workflow state \(.data[1].some_property) |
this is value from workflow state <workflow_state_data> |
\({x: 1, y: .a.b.c}) |
{“x”: 1, “y”: “<workflow_state_data>”} |
