PDA supports parsing Go templates. Actions are delimited with {{ }}.
|
|
|
|
For example:
|
|
'Hello, {{ .NAME }}' can be substituted with NAME="John Doe".
|
|
'Hello, {{ env "USER" }}' will fetch the USER env variable.
|
|
'Hello, {{ default "World" .NAME }}' will default to World if NAME is blank.
|
|
'Hello, {{ require .NAME }}' will error if NAME is blank.
|
|
'{{ enum .NAME "Alice" "Bob" }}' allows only NAME=Alice or NAME=Bob.`,
