# ITL - ilert template language

In the UI's text mode you may use the **Insert data...** dropdown to help you add template variables quickly - the text syntax works like this:

<table><thead><tr><th width="203">Type</th><th width="351.3333333333333">Sample</th><th>Description</th></tr></thead><tbody><tr><td>Text</td><td>Some text</td><td>You may of course add generic text content to your liking</td></tr><tr><td>Variable</td><td><strong><code>{{</code></strong><code>var</code><strong><code>}}</code></strong></td><td>Extract content of the event and insert it. Note: there is no further sanitizing of the values</td></tr><tr><td>Accessing nested variables</td><td><code>{{ var</code><strong><code>.</code></strong><code>subfield</code><strong><code>.</code></strong><code>evenMore }}</code></td><td>Access sub fields</td></tr><tr><td>Accessing fields of an array</td><td><code>{{ var.arrayField</code><strong><code>[0]</code></strong><code>.more }}</code></td><td>Access array contents</td></tr><tr><td>Applying functions to variables</td><td>{{<code>var.lowerCase}}</code></td><td></td></tr><tr><td><del>Passing arguments to functions</del></td><td><code>{{var.splitTakeAt('one two', 10)}}</code></td><td>We are in the process of reworking function calling in templates.</td></tr></tbody></table>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ilert.com/~/changes/vPSzQFfkdJCVWGT5AL1m/rest-api/itl-ilert-template-language.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
