Writs

A writ is an expression wrapped with {{ and }} that will be evaluated and output into the template.

Hello {{ name }}!

Hello Luna!

But writs support any expression:

{{ a }} + {{ b }} = {{ a + b }}

1 + 2 = 3

No matter how complicated:

{{ (user.name() | upper) ~ " (" ~ (user.company() | lower) ~ ")" }}

CASPER (sloths and stuff, inc.)

Expressions will be explained in more detail in a later chapter.

Escaping

Eventually you'll likely want to escape user-provided text for safe usage within a markup language. Set a default escaper group and manually specify the escaper anywhere the default escaper for the group won't work:

escaper_groups.html.escaper = "::oxiplate::escapers::HtmlEscaper"

<a href="/{{ attr: user.username }}" title="Visit {{ attr: user.name }}'s profile">
    {{ user.name }}
</a>

<a href="/toya_the_sequoia" title="Visit Isabelle &#34;Cat &amp; Mouse&#34; Toya's profile">
    Isabelle "Cat &amp; Mouse" Toya
</a>
