The logical parsing mode is used to construct logical expressions.

To construct these logical expressions, you can combine different elements, such as field codes, JWT expression parser functions and operators. The result must always return one of two distinct values: true or false. 

The main JWT features where you will be using the logical parsing mode are:

Example expressions

Parser expressionDescription
3 < 5

This example returns:

true 

3 > 5

This example returns:

false


Expressions can be combined or linked using operators to construct complex logical comparisons.


Parser expressionDescription
3 < 5 AND 7 > 5

This example returns:

true

%{issue.assignee} = %{issue.reporter}

This example returns:

true if the current assignee has also reported the issue, false otherwise

Parser expressionDescription
false
Simply returns false. You can use this expression for "switching off" a specific post function.
{parent.votes} > 5

A numerical comparison which returns true if the parent issue has more than 5 votes.

%{issue.assignee} = %{issue.project.lead} and %{issue.issueType} = "Bug"
(%{issue.assignee} = %{issue.project.lead}) and (%{issue.issueType} = "Bug")

A logical conjunction which takes two comparisons as operands.

It returns true when the assignee of the issue is the project lead and if it's a Bug.

The second expression has the same meaning but due to use of brackets may be more readable.

%{issue.assignee} = null

Returns true if the issue does not have an assignee. This expression uses the null value as an operator.

%{issue.priority} IN ["Blocker", "Critical"]
%{issue.priority} = "Blocker" OR %{issue.priority} = "Critical"

Returns true if the Priority has the value "Blocker" or "Critical". The first expressions uses a list whereas the second one uses single comparisons connected via the logical operator OR.

%{issue.issueType} = "Bug" IMPLIES %{issue.versions} != null

Returns true if Affects version/s is set whenever the issue type equals "Bug".

%{issue.priority} IN ["Blocker", "Critical", "Major"] IMPLIES (%{issue.assignee} != null AND %{issue.duedate} != null)

Returns true if Priority is "Blocker", "Critical" or "Major", the issue is assigned and Due date is set.

%{issue.labels} ~ ["Blocker", "Critical", "Major"]

Returns true if Labels (which is a field holding a ) contains "Blocker", "Critical" or "Major".
