Overview
if/else can be used to create conditional blocks.
The if control structures evaluate pipelines, not just values (values are a special case of a pipeline):
{{ if PIPELINE }}
# Do something
{{ else if OTHER_PIPELINE }}
# Do something else
{{ else }}
# Default case
{{ end }}
A pipeline evaluates to false
if the result of the pipeline, or the value, is:
- a boolean false
- a numeric zero
- an empty string
- a
nil
(empty or null) - an empty collection (map, slice, tuple, dict, array).
In any other case, the condition is evaluated to true.
