Condition syntax

Trigger conditions can be described by following list of operators, values and functions.

Operators

Logical

Operator	Description
`or`, `\|\|`	TRUE if either Boolean expression is TRUE. Example: [CommentType] = 'Public' or [Created] < '#01/01/2015#'
`and`, `&&`	TRUE if both Boolean expression is TRUE. Example: [AssignedTo] = '' and [AssignedTo] = [Editor]

Operator

Description

or, ||

TRUE if either Boolean expression is TRUE.

Example:

   [CommentType] = 'Public' or [Created] < '#01/01/2015#'

and, &&

TRUE if both Boolean expression is TRUE.

Example:

   [AssignedTo] = '' and [AssignedTo] = [Editor]

The and operator has more priority than the or.

Relational

=, ==, !=, <>
<, <=, >, >=

1 < 2

Additive

+, -

1 + 2 - 5

Multiplicative

*, /, %

5 * 5

Bitwise

& (bitwise and), | (bitwise or), ^ (bitwise xor), << (left shift), >> (right shift)

1 >> 5

Unary

!, not, -, ~ (bitwise not)

not true

Primary

(, )
values

(2 + 3) * 4

Values

Operator	Description
`[Prev]`	Return ticket item before changes. Example: ([Prev::Status] <> [Status]) and ([Status] == 'Solved')

Integers

They are represented using numbers.

Floating point numbers

Use the dot to define the decimal part.

123.456
.123

They are evaluated as Decimal.

Scientific notation

You can use the e to define power of ten (10^).

1.22e1
1e2
1e+2
1e-2
.1e-2
1e10

Dates and Times

Must be enclosed between sharps.

#2008/01/31# // for en-US culture

Booleans

Booleans can be either true or false.

true

Strings

Any character between single quotes ' are evaluated as String.

'hello'

You can escape special characters using \\, \’, \n, \r, \t.

Function

A function is made of a name followed by braces, containing optionally any value as arguments.

Abs(1), doSomehting(1, 'dummy')

Parameters

A parameter as a name, and can be optionally contained inside brackets.

2 + x, 2 + [x]
