Nunjucks is a sophisticated templating engine for JavaScript. It lets you insert dynamic content in any text through the use of templates. A template contains variables and/or expressions, which get replaced with values when a template is rendered; and tags, which control the logic of the template. See here for an overview of the templating features available in Nunjucks. Nunjucks in JMWE for JIRA Cloud is used to insert information while - Setting a field value by a post-function
- Commenting an issue by a post-function
- Conditionally executing a post-function
You can insert issue and transition information into the value using the templating features available in Nunjucks. Some basic templating features are described in this document, and more are documented on the Nunjucks website. |

A variable looks up a value from the template context. If you want to insert the value of a variable in your template, you can use the following syntax: {{ myVar }}. This looks up for the myVar variable from the context and displays it. Variable names can have dots in them which look up properties, just like in javascript.
Variables available in JMWE
JMWE makes the issue, transition, linkedIssue, parentIssue, now and currentUser variables available to templates. You can access their properties using "." or "[ ]". For example, you can access the current issue key using {{issue.key}}.

User-defined variables
In addition to the above variables, you can also create your own variables within the template using the set Nunjucks tag.
For example:
{% set x = "High" %} sets the value of the variable x to High. You can also set the variable to an object. For example: {% set assignee = issue.fields.assignee %}
...
The isInGroup filter is a custom Nunjucks filter that returns true if the user is in the specified group (passed as a parameter to the filter). The user, provided as input to the filter, can be either a username or a user object.
For example:
{{ currentUser | isInGroup("jira-administrators") }} returns true if the current user is in the "jira-administrators" group.
