Writing Conditional Statements
Text templates can conditionally produce text for input to a brick.
If there are only 1 or 2 simple cases, you can write the condition inline as an expression:
{{ "Meow" if @animal == "cat" else "Woof!" }}
Text Templates are the most convenient way to provide a Condition that controls if a single brick runs.

Using a Text Template condition expression to control when a brick is run.
Text Templates can also provide the condition for the If-Else brick. The If-Else brick can run multiple bricks if a condition is met.
PixieBrix text templates support comparison and logical operators in expressions:
==,!=: equals and not equals>,<,>=,<=: numeric comparisonand,or: logicnot: negation
Here’s an example showing comparison and logic in an expression:
To provide multiple conditions using
and or or, provide them within the same template expression {{ true if @run > 0 and @animal == "cat" }}
If there are multiple cases, or one or more cases are multi-line, you can use condition blocks to provide the cases:
{% if @animal == "cat" %}
Meow!
{% elif @animal == "dog" %}
Woof!
{% else %}
???
{% endif %}
As you can see, blocks are designated using
{% and %} instead of the {{ mustache braces. The tags are if, elif, and endif.Note that alternative cases use the
elif tag with no space. I.e., as opposed to else if which is used in many programming languages
✅ elif
❌ else if
