This page presents a collection of expressions valid for the Expression Parser.
Math Calculus
| Expression | Returned Value | Notes |
|---|---|---|
max(count(subtasks(%{00041})) - 1, 0)or since version 2.2.1: count(siblingSubtasks()) | For a sub-task, the number of sibling sub-tasks. | Function max(x, y) is used to avoid returning -1 when used with non-sub-task issues.%{00041} = Parent's issue key |
{10000} = null ? 1 : {10000} + 1or since version 2.2.16: sum([{10000}]) + 1 | Formula to increment a numeric custom field, setting it to 1 if it's initially unset. | {10000} is the field code for a supposed numeric custom field. |
{10000} + {10001} + {10003} | Formula for summing 3 numeric custom fields when we are certain that all 3 the fields are initialized. In case any of these fields is not initialized, an error is raised and any of the following 2 expression examples should be used. | {10000}, {10001} and {10003} are three numeric custom field. |
({10000} = null ? 0 : {10000}) + ({10001} = null ? 0 : {10001}) + ({10003} = null ? 0 : {10003}) | Formula for summing 3 numeric custom fields when some of them may be uninitialized. When any of this fields is not initialized a zero value is assumed. | {10000}, {10001} and {10003} are three numeric custom field. |
sum([{10000}, {10001}, {10003}]) | A more compact syntax for summing 3 numeric custom fields when some of them may be uninitialized. Version 2.2.16 or higher is required. | {10000}, {10001} and {10003} are three numeric custom field.This syntax is available since version 2.2.16. |
Date-Time Calculus
| Expression | Returned Value | Notes |
|---|---|---|
{00012} - 6 * {DAY} | Calculates a date 6 natural days earlier than Due Date | {00012} = Due Date |
addTimeSkippingWeekends({00009}, 36*{HOUR} + 45*{MINUTE}, LOCAL) | Returns a date-time value equivalent to adding 36 hour and 45 minutes to date and time of issue creation, skipping the periods of time which correspond to weekend. | {00009} = Date and time of creation |
addTimeSkippingWeekends({00009}, 36*{HOUR} + 45*{MINUTE}, LOCAL, {FRIDAY}, {SATURDAY}) | Same as previous expression, but using Israeli weekend. | Israeli weekend is on Friday and Saturday. |
addDaysSkippingWeekends({00012}, -6, LOCAL) | Calculates a date 6 work days earlier than Due Date for Jira Server's local timezone. | {00012} = Due DateWork days depend on timezone, since certain time moment maybe Sunday in certain timezones, and Monday in another ones. |
subtractDatesSkippingWeekends({00012}, {00057}, LOCAL)/{DAY} | Returns the number of working days from Current Date and Time to Due Date, i.e., skipping weekends in Jira server's timezone. | {00012} = Due Date{00057} = Current day and time |
round(({00057} - {00009}) / {HOUR}) | Number of hours since issue creation | Function round() approximates the number of hours to the nearer integer.{00057} = Current day and time{00009} = Date and time of creation |
floor(({00012} - {00057}) / {DAY}) | Number of days to Due Date | Function floor() approximates the number of days by removing the fractional part.{00012} = Due Date{00057} = Current day and time |
datePart({00057}, LOCAL) + (dayOfTheWeek({00057}, LOCAL) = 7 ? 6 : 6 - dayOfTheWeek({00057}, LOCAL)) * {DAY} | Returns a date value for next Friday, or for today if it's Friday | {00057} = Current day and timeExample |
datePart({00057}, LOCAL) + (dayOfTheWeek({00057}, LOCAL) = 6 ? 7 : (dayOfTheWeek({00057}, LOCAL) = 7 ? 6 : 6 - dayOfTheWeek({00057}, LOCAL))) * {DAY} | Returns a date value for next Friday, even if today is Friday. | {00057} = Current day and timeExample |
Date-Time Calculus on Custom Schedules
Custom Schedules are supported since version 2.2.39.
We use Custom Schedules when we need to do time calculations within the work-schedule of our company or organization, e.g., we want to count only the time from 8:00 to 15:00, and from 16:00 to 19:30.
Functionality provided by functions addTimeSkippingWeekends() and subtractDatesSkippingWeekends() can also be implemented using Custom Schedules, and much much more.
Your Custom Schedules are defined in Jira at Administration > Add-ons > JIRA WORKFLOW TOOLBOX > Schedules.
| Expression | Returned Value | Notes |
|---|---|---|
timeDifference({00012}, {00057}, "my_schedule", LOCAL) | Returns the resting time to Due date within my_schedule custom schedule. | {00057} = Current day and time{00012} = Due date |
addTime({00057}, 24 * {HOUR}, "my_schedule", LOCAL) | Returns a date-time value (i.e., an instant in time) obtained by summing 24 hours to current date-time within my_schedule custom schedule. | {00057} = Current day and time |
Showing Time Durations in Pretty Format
The following examples are string expressions in advanced parsing mode.
| Expression | Returned Value | Notes |
|---|---|---|
| Calculates the time since issue creation, and shows it as a text using whole words like: 12 days 6 hours 34 minutes. | {00057} = Current day and time{00009} = Date and time of creation |
| Calculates the time since issue creation, and shows it as a text using abbreviations like: 12 d 6 h 34 m. | {00057} = Current day and time{00009} = Date and time of creation |
| Calculates the time since issue creation skipping weekends, and shows it as a text like: 12 days 6 hours 34 minutes. | {00057} = Current day and time{00009} = Date and time of creation |
| Calculates the time since issue creation, and shows it as text, but using the workday and workweek defined at time tracking configuration instead of 24 hours per day and 7 days per week. | Example: formatWorkDuration(24 * {HOUR} + 5 * {MINUTE}) returns "3 days 5 minutes" when we use 8 hours per workday. |
| Similar to the previous expression but shows the result using abbreviations instead of whole words. | Example: shortFormatWorkDuration(24 * {HOUR} + 5 * {MINUTE}) returns "3d 5m" when we use 8 hours per workday. |
