This list aims to be a comprehensive list of default functions available with Presence 3.6.2. Please note that it is a work in progress.

Boolean Functions

&equalsString{VAL1, VAL2}

This function compares String1 and String2. If they are equal it will return the value "true". Otherwise it will return "false".

&equalsString{"ABC","ABC"}
Returns true
&equalsString{"ABC","BC"}
Returns false


&if{VALUE, TRUE_RESULT, FALSE_RESULT}

This function performs a test on a string. If it equals "true" or "1" the value of Parameter 2 will be returned. Otherwise, value of Parameter 3 will be returned.

&if{"true", "I AM TRUE", "I AM FALSE"}
Returns "I AM TRUE"
&if{"0", "I AM TRUE", "I AM FALSE"}
Returns "I AM FALSE"

Data Functions

&onDemand{taskAlias, parameter+}

taskAlias: The alias of the Task to be called, the task should be on the Live Tasks Queue #On Demand Processes

&onDemand{"myTask","id=5", "now=true"}

Calls the Task referenced by the alias "myTask" and sets the following variables:

${id} = 5 ${now} = true

If the task returns a magic ${response} variable that value will be populated in the variable or space you are calling the function from.

&doesColumnExist{"COL_NAME"}

Tests to see if the specified column name exists in the current data table - returns "true" if it does or "false" if not.

Parameter 1: The column name to test

Returns 08/08/2015 (minus 5 days from the current date)
&currentDate{"dd/MM/yyyy",-3M}
Returns 13/05/2015 (minus 3 months from the current date)
&currentDate{"dd/MM/YYYY",5}
Returns 18/08/2015 (plus 5 days from the current date)

&adjustTimeZone{Date in originating timezone,Format of date in param 1, Originating timezone, Resulting timezone, Resulting date format (OPTIONAL)}

This function adjusts a given date from the source timezone to another timezone. For example, an event happens in San Fransisco at 03:00 AM but the time needs to be displayed in London, which would be 11:00 AM.

Usage: &adjustTimeZone {"2013-08-02 03:00", "yyyy-MM-dd HH:mm", "US/Pacific", "Europe/London"}

There is an optional 5th parameter which is the format to be used when creating the string that is returned. If it is omitted then the format specified in the 2nd parameter is used.
