Angular is a javascript framework for creating dynamic views. In Teragrep, Angular is a standalone interpreter and a compilation of HTML and Javascript.

Teragrep is currently using v1.5.7 of AngularJS library which support officially ended in January 2022. Read more here.

To use Angular in Teragrep’s editor, write %angular at the start.

<p>Body text</p>


You can use Bootstrap components and utilities with %angular. Check the comprehensive list from Bootstrap documentation.

<div class="row">
    <div class="col-3">
        <div class="list-group">
          <a href="#" class="list-group-item list-group-item-action active" aria-current="true">
            The current link item
          <a href="#" class="list-group-item list-group-item-action">A second link item</a>
          <a href="#" class="list-group-item list-group-item-action">A third link item</a>
          <a href="#" class="list-group-item list-group-item-action">A fourth link item</a>
          <a class="list-group-item list-group-item-action disabled">A disabled link item</a>
    <div class="col">
            Bootstrap Content
            <small class="text-muted">With faded secondary text</small>
        <p class="lead">
            This is a lead paragraph. It stands out from regular paragraphs. Use it as an ingress in body text.
        <p class="mb-4">
            <i class="fa-solid fa-user text-muted me-2"></i> John Doe <br />
            <i class="fa-solid fa-clock text-muted me-2"></i> <i>January 2022</i>

Bootstrap content


When dashboards are made with %angular, the output is treated as a view template for AngularJS. AngularJS compiles the template and displays it in Teragrep which provides the gateway between selected interpreter and the compiled template.

Back-End & Front-End APIs

You can create forms with back-end API or front-end API. Both back-end and front-end APIs are similar. The only exception is the value watching action:

  • In front-end, done by AngularJS internals

  • In back-end, done by a user’s custom watcher functions

In addition, the front-end API limits the Angular object binding to a paragraph scope whereas the back-end API allows to bind the Angular object to the global or notebook scope.

Table 1. Differences in the front-end and back-end APIs
Action Front-end Back-end


z.angularBind(var, value, paragraphID)

z.angularBind(var, value)


z.angularUnbind(var, paragraphID)


Execute paragraph


Execute paragraph in a different notebook

Unavailable, paragraphID)

Execute notebook



Update value

z.angularBind(var, newValue, paragraphID)

z.angularBind(var, newValue)

Watch value

z.angularWatch(var, (before, after) ⇒ { …​ })


To style your forms, use Bootstrap components and utilities.

<div class="row mb-4">
    <div class="col-auto">
        <label class="form-label">First name</label>
        <input class="form-control" type="text" placeholder="John" />
    <div class="col-auto">
        <label class="form-label">Last name</label>
        <input class="form-control" type="text" placeholder="Doe" />
<div class="form-check mb-4">
  <input class="form-check-input" type="checkbox" value="" id="flexCheckDefault">
  <label class="form-check-label" for="flexCheckDefault">
    I solemnly swear I didn't read the terms of use.
<button type="send" class="btn btn-primary me-2">Send</button>
<button type="text" class="btn btn-secondary">Cancel</button>
