My personal experience with velocity is more of a try & fail, try & fail,
try and succeed one than anything else. What I found out is that I was msot
of the time better off rewriting stuff starting with small chunks rather
than trying to take existing code and reuse it all at once. The current blog
is a fairly complex piece of velocity code (that is, given the lack of
debugging tools when coding in velocity in the wiki). This is one of the
reasons I think Sergiu's argument that "devs will be able to look at the
code and learn from it" is not entirely true ;-)
What's really important for the blog is that it can be customized easily at
2 levels:
- Look: an user should be able to use the panels she wants for her blog
- Deployment: an user should be able to create a new space blog or global
wiki blog in any space she wants
Besides that the way the blog is code doesn't matter much for the end user.
That said I still think that it might be a good idea to convert the
scripted part of the Blog over to Groovy and keep the
rest in the Blog
Plugin. I don't have any experience with Groovy inside XWiki but for
sure the documentation of Groovy outside is excellent compared to
Velocity. I will use the next week to get up to speed and try to
convert a piece of the Blog over to Groovy.
Then go ahead and give it a go :-)
One thing you need to be aware of when using Groovy inside the wiki is that
your pages will haveto be saved using programming rights. This can cause a
number of issues, don't forget to code with an user that has them, it will
save yo ua lot of hassle ;-)

Good luck and thanks for all the nice work,
Guillaume

This is not really related to velocity which is the simplest language
on earth. It's related to any language you type without an IDE to help
you. Try using groovy in wiki pages you'll have the same problem (I
know I have it, I need to preview 10 times to get something right).
That said, there are some velocity editing support in IntellilJ IDEA
and I think there's also a plugin for Eclipse which might help. You
can also use XEclipse which has syntax highlighting and some
autocompletion for velocity (you'd need to use the 1.2RC1 version).

I encounter this issue when I tried to create a new blog entry within

what is going on but I don't. First I don't know when the programming

user Admin) I still cannot pass that check.
The Create Post which calls the inline blog edtior (see CreatePost
when a name is given) falls even though no page is created yet. For
now it seems I cannot only create a new post when both the CreatePost
page as well as the BlogPostTemplate is written in velocity.
BTW I use 2.0m4 as the code base.

Hi
I got over that. It is not pretty and I don't know what went wrong but
I finally could find a good compromise. What I did was to use a
Velocity script that then parsed and loaded a Groovy class which
contained the code for the Blog Post Template. This way there was not
check and it so I could pass this issue.
That said I wasted some hours casing the issue where no entry object
could be found until it dawned on me that the Blog Post Template not
only contains the Wiki code but also and instance of the Blog Post
Class, silly me.
I am still working on getting the last kinks out but I think I
mastered the most difficult issues.
Soon I have to decide if I want to create a two prong Blog application
or if I create a second Blog application (GBlog) that contains the
Groovy code. Most likely the point that decides on which way to go is
the fact if I can keep the Blog documents already written.
Cheers - Andy
