The JWT for Jira Cloud expression parser provides a huge set of functionalities to read and manipulate data from Jira issues, users, projects and more.

The main point of contact with the expression parser for the end user is the JWT expression editor.

Depending on what you are doing, you will be presented with different options and functionalities, but in the end it always comes down to writing an expression, which will be evaluated on runtime.

 

Syntax check

  1. As you type in your expression the syntax check button is synchronized with your expression and you can see if your expression is valid or not.
  2. Click on the syntax check button to review your expression.
OutputDescription

Valid expression: The parser expression entered is valid.

Parsing error: The parser expression entered is not valid and you can do the following to fix the issue:

  • Check your selected Parsing mode
  • Try an example configuration from the right hand side of the configuration interface
Parsing mode selector


A parsing mode determines how the JWT for Jira Cloud expression parser interprets an expression. The available parsing modes depend on the context in which you use the expression.



Read more about all available parsing modes.


Field code injector

The field code injector is a dynamic select list that lists all available field codes. The fields, or their values, will be be replaced with actual values at runtime.

The available fields and their notation depend on the selected Parsing mode.

This is where you can enter a plain text and optionally use Field codes and functions belonging to the selected parsing mode. 

Which options you will actually have depend on the selected Parsing mode.

A powerful feature of the editing area is auto-completion.
