Expression Language Built-In Variables

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.  


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.
