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 expression Description

Code Block

linenumbers	true

3 < 5

This example returns:

true

Code Block

linenumbers	true

3 > 5

This example returns:

false

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

Parser expression Description

Code Block

linenumbers	true

3 < 5 AND 7 > 5

This example returns:

true

Code Block

linenumbers	true

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

This example returns:

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

Parser expression

Description

Code Block

linenumbers	true

false

Simply returns false. You can use this expression for "switching off" a specific post function.

Code Block

linenumbers	true

{parent.votes} > 5

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

Code Block

linenumbers	true

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

Code Block

linenumbers	true

(%{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.

Code Block

linenumbers	true

%{issue.assignee} = null

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

Code Block

linenumbers	true

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

Code Block

linenumbers	true

%{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.

Code Block

linenumbers	true

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

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

Code Block

linenumbers	true

%{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.

Code Block

linenumbers	true

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

Returns true if Labels (which is a field holding a

) contains "Blocker", "Critical" or "Major".
