Global Variables

Overview

Global variables let you define Trill expressions once and reuse them across all your triggers using the {{varname}} syntax.

Creating a Variable

1. Open the Trigger Manager
2. Navigate to the Variables tab
3. Click Add Variable
4. Set the Name (e.g., fullname)
5. Set the Expression (a Trill expression, e.g., "John Doe")
6. Click Save

Using Variables

Reference variables in any trigger replacement:

Abbreviation: ;;sig
Replacement: Best regards,\n{{fullname}}

Variables can contain any Trill expression:

Name	Expression	Result
fullname	"John Doe"	John Doe
email	"john@example.com"	john@example.com
date_today	today("%m/%d/%Y")	05/13/2026
hour_12	to_num(now("%H")) % 12 || 12	2

Variable Resolution Order

When a trigger replacement is expanded, variables are resolved in this order:

1. Global variables are evaluated first (they can reference each other by name)
2. Trigger-level variables are evaluated next (can reference globals)
3. Built-in variables ({{date}}, {{time}}, etc.) are resolved
4. Trill expressions ({{...}}) in the replacement text are evaluated last

This means a global variable can contain a Trill expression {{today("%B")}} that gets evaluated when the variable is used.

Use Cases

• Store your name, email, or contact info once
• Define reusable formatting logic
• Keep consistent snippets across triggers
• Update a value in one place and all triggers reflect the change
