The JWT expression parser is the brain of JWT.It provides JWT provides a huge set of functionalities to read and manipulate data from Jira issues, users, projects, and more.

The "expressions" that are being evaluated by the expression parser are composed and tested in 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.

titleWhat is an expression?

Expressions are a fundamental concept within Jira Workflow Toolbox: every input into the JWT expression editor is considered an expression and will be interpreted by the JWT expression parser against the selected parsing mode. They are used in workflow functionsautomation rules, and calculated fields.

Expressions range from simple text, e.g. Hello world!, over mathematical calculation, e.g. 3 + 4, to the extensive usage of expression parser functions, and beyond.
