| <strong>Directive Interface</strong> |
| <br /> |
| Right now there is a very thin interface for directives, but |
| some knowledge of JavaCC is required. The directive |
| interface is not intended to be used outside core Velocity |
| developers (it is not intended to be a public API), but it |
| probably makes sense to shield directive creators from JavaCC. |
| </p> |
| <p> |
| <strong>Caching</strong> |
| <br /> |
| It would be good to have a discussion about how objects |
| in the context should be cached, how the caching |
| should be specified, and who should control the |
| caching: the designer, by specifying something in the template; |
| the developer, |
| by placing expiry times on objects placed in the context; |
| or a third party, such as a content manager. For example, |
| say an array consisting of a top 10 list of books is |
| placed in the context. This top 10 list might be valid |
| for a 24 hour period: how should that be specified? Say |
| a content manager later decides this list will be valid |
| for a week. Do they tell the designer, who in turn changes |
| the template, or could we provide a mechanism that would |
| allow a content manager to change the default expiry time |
| for that particular context object with the aid of a webapp |
| of some sort? The groundwork has be laid for a flexible |
| caching system in Velocity, but this discussion would be |
| one of usage and policy. |
| </p> |
| <p> |
| <strong>UML Overview</strong> |
| <br /> |
| It would great to include a set of comprehensive |
| UML diagrams that describe Velocity. This would |
| allow new developers to get up to speed quickly. |
| </p> |
| <p> |
| <strong>Velocity Profiling</strong> |
| <br /> |
| If someone is handy with one of the standard profilers, |
| it would be great to start hunting for bottlenecks. No |
| serious optimization has been started. But in conjuction |
| with the presence of a JUnit test suite, optimization |
| changes could be made with confidence. It would be nice |
| to have a configuration of a setup for a common profiler |
| so that anyone who wanted to do some profiling could do |
| so in a consistent manner. |
| </p> |
| <p> |
| <strong>Syntax Dumper</strong> |
| <br /> |
| Right now there is a primitive syntax dumper in the Velocity |
| code base, and it could be improved. This tool is very helpful |
| in debugging, and it is also good for creating directives. |
| It basically has a simple dump method that is used for all |
| the AST node types. It would be good to tailor dump methods |
| for particular AST node types so that the structure produced |
| is a little clearer. |
| </p> |
| <p> |
| <strong>Syntax Checker</strong> |
| <br /> |
| It would be good to have a standard syntax checker, something |
| that would find all syntax errors and report them to the |
| designer in some intelligible format. This tool could be |
| hooked into various designer tools like DreamWeaver. |
| </p> |
| <p> |
| <strong>Compiler</strong> |
| <br /> |
| It would be great to have a template compiler. There is a great |
| utility called JavaClass that provides a very clean and simple way |
| to create class files, and there is also some byte code generating |
| code present in the DynamicJava package that could be utilized. |
| </p> |
| <p> |
| <strong>IDE Integration</strong> |
| <br /> |
| How could Velocity be integrated into standard IDEs like |
| JBuilder and VisualAge? |
| </p> |
| <p> |
| <strong>Scripting Language Integration</strong> |
| <br /> |
| This is something that has been discussed on the Turbine |
| list. Allowing Context building classes to be written |
| in JPython, Rhino or other scripting languages would |
| dramatically improve development time and might allow technically |
| proficient web designers who are familiar JavaScript to create |
| an entire servlet solution with Velocity. As most of these |
| scripting solutions provide a compiler, performance would still |
| remain at an acceptable level. |
