--------------------------------------
Summary: Allow to override current date and time in `.now` built
in variable
Key: FREEMARKER-179
URL: https://issues.apache.org/jira/browse/FREEMARKER-179
Project: Apache Freemarker
Issue Type: Improvement
Components: engine
Affects Versions: 2.3.29
Reporter: Jan Novotný
It would be handy if `.now` variable can be overriden by a custom code to a
fixed date. My use-case is rather special - we use Freemarker in directmailing
app when e-mails are generated for several minutes (date and time changes) but
I need to have fixed date and time for the sake of statistics gathering. I've
prepared special variable `sentDate` but the developers keep using `.now` and
cause problems by this.
It's hard to fight the habit, so that it would be useful for me to override the
"now" for certain scope of Freemarker generation process and just alter "now"
that is correct for my use-case but it's not possible now - in
`freemarker.core.BuiltinVariable#_eval` the `now` variable is defined as `new
Date()` which cannot be changed in any way.
Another use-case when this may be helpfull is for junit testing - when fixing
date and time is required for repeatability of the test execution that uses
`.now` inside tested FreeMarker template.
Thank you for consideration.
