> Easily Add/Remove/Replace Directives Without Cracking Open Velocity Jar

> Key: VELOCITY-742
> URL: https://issues.apache.org/jira/browse/VELOCITY-742
> Project: Velocity
> Issue Type: New Feature
> Components: Engine
> Affects Versions: 1.6.2
> Reporter: Tim White
> Priority: Minor
> Fix For: 1.7
> 
> Attachments: velocity-742.patch

> There are two use cases that I have for this issue:
> 1) We need to turn off #include in order to parse .html files that include SSI \
> directives:  <!--#include virtual=""-->  (we always use #parse in our world, so no \
> loss for #include going away) 2) We need to supply our own version of #parse that \
> contains the development hooks that I described in a different issue. Right now, \
> the only crisp way to do is is to crack open the velocity .jar and make these \
> changes, which is very risky, because future developers may upgrade to new versions \
> of Velocity and not realize that there are customizations and/or not understand how \
> to remake them....not to mention in a shared-classpath environment, we don't always \
> have control over which copy of the Velocity .jar we're using. Ideally, there would \
> be config options like this: directive_remove ("#parse", "#include")
> directive_add ("#parse", "com.qwest.velocity.directives.Parse")
> Thanks!
