How to insert information using Nunjucks annotations

Introduction to Nunjucks

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.

Templating features in Nunjucks

  • Nunjucks template editor and tester
  • Variables used in Nunjucks templatesA variable looks up a value from the template context. This documents details on the variables available in JMWE and how to create custom variables.
  • Built in Nunjucks FiltersFilters are essentially functions that can be applied to variables. This document details some of the Nunjucks built-in filters.
  • Custom Nunjucks filtersFilters are essentially functions that can be applied to variables. Filters are called with a pipe operator (|) and can take arguments. This document details custom Nunjucks filters created for JMWE.
  • Tags and ExpressionsTags are special blocks that perform operations on sections of the template and Expressions are literal expressions similar to those in javascript.
  • Accessing the details of an issue or a transition in NunjucksThis document explains how to access the details of issue and transition objects, such as those available through the issue and transition variables. To see an example of the structure of an issue go to <base_URL_of_Jira>/rest/api/latest/issue/{issueKey}. The fields displayed through this REST API actually depend on the fields set on the issue. 
  • Conditional executionPost functions are provided with an option to control their execution. You need to input a Nunjucks template in the Condition field, and based on the result of that expression, the post-function will either be executed or skipped.
  • Shared Nunjucks Templates
