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.
