[ http://issues.apache.org/jira/browse/VELOCITY-454?page=comments#action_12432794 ] Henning Schmiedehausen commented on VELOCITY-454: -------------------------------------------------
I agree that the current parser sucks in that respect. As I wrote in the User Guide, it is mind-boggling that we came up with this, but it is actually tied to how the parser works. I don't see us to be able to fix this in the 1.5 time frame, so I postpone this to 1.6. > clean up escaping to always escape \$ and \# > -------------------------------------------- > > Key: VELOCITY-454 > URL: http://issues.apache.org/jira/browse/VELOCITY-454 > Project: Velocity > Issue Type: Improvement > Components: Source > Affects Versions: 1.4 > Reporter: Bjoern Guenzel > Attachments: testVelocity.vm > > > I want to use Velocity to generate a template for UJAC, which uses a very > similiar templating language to Velocity. Therefore escaping is a primary > concern. > I am surprised that there seems to be no way to just escape "$" and "#" in > general. > Suppose we have the line \$name > If name is in the context, this will evaluate to $name, otherwise it will > evaluate to \$name > The real problem starts if there is something to escaped like > ${something == 3} (this is something that might occur in a UJAC template) > This gives an error in both cases: ${something == 3} and \${something == 3} > both give an error ("} expected" or something like that). > My guess is that Velocity get's confused when trying to evaluate "something > == 3" to see if it is something that is known and should be escaped or > something that is unknown and should not be escaped. > In my opinion the proper behaviour for escaping characters would be to ALWAYS > escape, independent of the context. > Even if the current way of escaping would work in all cases, there would be a > major problem with it. I can't give the velocity template to the Designer, > because only the developer knows all the variables that exist in the context. > So the designer is unable to properly escape all the variables. I think it > would be important to have a way to simply escape everything. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
