[jira] [Closed] (VELOCITY-845) User Defined Character Replacement
for the "$" Sign.
[ https://issues.apache.org/jira/browse/VELOCITY-845?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Claude Brisson closed VELOCITY-845.
-----------------------------------
Resolution: Won't Fix
Assignee: Claude Brisson
Fix Version/s: 2.x
I agree that it could be a nice feature. The day Velocity uses its own parser, it may be possible. But for now we're using Javacc, which doesn't allow such customization.
On the other hand, it is definitely doable at compile time in the Javacc source file (and a few other places in parser/nodes).
Nevertheless, *most* of the time, Velocity and jquery code cope pretty well together, Velocity leaving aside $vars that don't exist in the context. When a problem occurs, you still have escaping: just prefix the reference with a backslash.

> Would be of huge help if Velocity would allow the users to define a character replacement for the "$" sign, e.g. using the velocity properties:
> http://velocity.apache.org/engine/releases/velocity-1.7/developer-guide.html#Velocity_Configuration_Keys_and_Values
> with a new one like:
> variable.sign.redefine=€
> The $ sign is a good default for many situations, but it's very bad for web stuff and JavaScript code. Escaping could be avoided by allowing the user to use something else.
> tnx.
