news: Velocity used in Intellij IDEA
Howdy folks -
I just received some code generation templates for IntelliJ IDEA from
one of my colleagues and noticed that they use Velocity. I didn't see
this in the "Powered By" page, perhaps worth adding.
-Timo
>From the IntelliJ IDEA 3.x help system:
IntelliJ IDEA provides several built-in templates for creating new
files, classes and interfaces, as well as some supplementary templates
to be automatically used when generating particular blocks of code.
Along with using the built-in templates, you can easily create your own.
To view/edit the existing templates, or to define your own, select the
Options | File Templates menu item. The File Templates dialog will
appear, containing the following three tabs:
Templates - for file templates Includes - for code fragment
templates to be dynamically included into the file templates Code -
for code templates
...
When writing or editing templates, you can use built-in and custom
variables, conditional directives, etc. which are briefly described in
the Description field of the File Template dialog. For more details on
template syntax, please, refer to
http://jakarta.apache.org/velocity/user-guide.html.

But I wouldn't want to be the one maintaining the separate engines,
in several different languages... I have written a couple of compilers
in C before, I don't think it would be that hard.
The one thing I could never assess was how easy it would be to design
a generic interface for each language "skin". What would you need to
support in this interface?
* Access to a "context".
* The ability to introspect.
* The ability to call methods in objects placed in the context.
* Anything else?
That's about it. The rest of the code could be implemented ONCE in C.

Yeah. It sounds interesting to me, no one ever agreed though...

.Net/C# has already been done. :-)

I wonder if there is an equivelant to JavaCC for the other languages.

I like this because it makes it easier to hook into engine of the day,
but the pain of writing a templating engine in C... It would be
probably easier do separate Perl, Ruby, Python, and C# implementations
than write one in ANSI C and write wrappers for each I think =/

That be the idea. Couple it with a Context Service (ie, extract the
Context via JAXB and equivalents in other languages) and things get
interesting. In theory you can define your services to be pretty
transparent. As webapp contexts are pretty close to single-thread
oriented most of the time you can cache them very aggressively and be
okay - but this is worrying about performance way too early.

I once faced a similar project, where we needed some PHP-
and Perl-backed pages. I thought the simplicity and power
of Velocity were just perfect for my needs. At one point,
I charted the following plan:
* Write a Velocity-compatible template engine in C, with
hooks for everything that could be environment dependent,
like how to access a context, how to call an object's
method, how to access an object's properties, etc.
* Write "flavors" for this engine in each desired language.
The first one would be Java, as a proof of concept.
Alas, I never found the time to do this. I still believe
it could be a good way to spread Velocity to other languages
and/or environments. Imagine that! One set of template pages,
many possible "back-ends".

You might want to have a look at http://freshmeat.net/articles/view/447/
for an article which discusses creating a basic template engine in
Ruby. Should be pretty easy to build one from there, especially with
the regex support.

Alternate Language Engine
Posted by Brian McCallister <mc...@forthillcompany.com>.
Hello all,
This may be a bit way off-scope (particularly as Jakarta is Java
centric) but I have a problem I would like to solve via Velocity which
I cannot quite yet.
Basically I need to integrate look and feel of several web applications
that are spread across Java and Ruby. The Java side of the application
is planning to use Velocity for page generation, and the Ruby side
is... planning to use eruby (think ASP/PHP but with Ruby) unless I can
come up with something better. I am attempting to do this so that we
don't wind up maintaining twice the templates for common things
(top/bottom/left etc).
I would dearly love to use a common set of templates between all of the
components (be they ruby, Java, or... whatever else winds up being
grafted on down the line).
So, does anyone know of any effort to port a VTL engine to Ruby? As I
am pretty confident that no one has done this yet - is anyone familiar
with the inner workings of VTL interested in helping to build one?
Thanks,
Brian
