.if

This directive allows for the selection of a single branch (or none) by use of a condition. This directive takes two forms:

.if{condition}{branch}
.if{condition}{branch 1}{branch 2}

The two-argument form operates as follows:

• If condition is true, branch is returned
• Otherwise nothing is returned

The three-argument form operates as follows:¹

• If condition is true, branch 1 is returned
• Otherwise, branch 2 is returned

Example -- Greetings message

Assuming that the variable !is_morning contains a value which represents whether the current time is morning, we could tailor the user’s greeting message to the current time.

.echo:
	.if{!is_morning}:
		Good morning!
	::
		Hello!
