Built-In Variables

A number of "built-in" variables are provided as part of the Expression Language. These can be used simply wrapped in the standard ${ } Expression wrapper. They can only be used as part of Expression Language.

How to Use These

These built-in variables can be used, like the Boolean constants true and false directly, without further qualification and without quotes (emphatically without quotes), directly in Expressions.

Examples

Date Examples

${today} - This gives the value "today's date" in ready-to-print MM/dd/yyyy hh:mma format.

${now} - This gives an "as accurate as possible" current date and time in the same MM/dd/yyyy hh:mma format.

To use "today" as a comparator you need a "raw" or 'non-String' version. This is available as "today_raw" or "now_raw".

rw:dateCompare(row.someUsefulDate, today_raw)

School Year Example

The schoolYear variable gives the current system setting for the School Year. This is a String. E.g. 2024-25, 2025-26.

${schoolYear}
