A parsing mode determines how the JWT expression parser interprets an expression. 

The available parsing modes depend on the context you are using the expression in. This means for example, that only the Logical mode is available if you configure a conditional execution in a workflow post function or that you can only use the Number mode if you want to set a number field using a parser expression.

Most functions will accept text values so casting values to text is a very powerful function. Details can be found below in the converting data types section!

Additionally, you can directly transform a field value to text using the following syntax: %{...somefield}




ModeSupported featuresReturn typeExample
BasicField codes




The basic parsing mode supports the usage of field codes. Field codes can be used to access issue field values.

This is the issue summary: %{trigger.issue.summary}


Advanced

Field codes

Parser Functions

The advanced parsing mode has a defined syntax that allows you to write functions to read and manipulate data from any issue in Jira. Field codes are supported as well as clear text, written in quotation marks.

This is the issue summary:" + %{trigger.issue.summary} + " and the assignee mail is: " + userEmail(%{trigger.issue.assignee})


Math/date-time

Field codes

Parser Functions

The mathematical and date time parsing mode works like the advanced mode but expect a number as result instead of a string. The resulting number is used to updated numeric or date time fields. In case of date or date time fields the number will be cast to a date.

{trigger.issue.resolutionDate} - {trigger.issue.createdDate}


Logical

Field codes

Parser Functions

The logical parsing mode works like the advanced parsing mode but expression result must return true or false.

{trigger.issue.assignee} = {trigger.issue.reporter}

You can write your text in basic mode, and then switch to advanced mode using Automatic parsing mode converter.

The text to be parsed will be automatically rewritten as a string expression. Now, you can simply make the modifications you require, making use of text formatting functions, or inserting math or time expressions where needed.

To update issue fields the parsing result will be cast to the expected value e.g. a user name will be cast to a user to update a user field like the assignee field.
