Hi,
I just did a test upgrade of a site from Velocity 1.6.2 to Velocity 1.7. A
number of my templates started to fail because they included square
brackets. (Ironically, we discovered this soon after I finished describing
to my coworkers the project's obsessive stance on backwards compatibility).
My pages often reference mathematical values, and the bracket is a common
part of the text.
This used to work
#for($var in $varList)
$abc[sub1]
#end
which would print something like
Sales[sub1]
Revenue[sub1]
Cost[sub1]
etc
Now it gives a parse error.
I see that ${abc}[sub1] keeps the old behavior. However, searching our site
there have 40+ pages with many of these now illegal references. (Many by
other authors).
Any suggestions as to how I can keep the backwards compatible parsing
behavior?
I'll dig into the Velocity code, see if I can think of anything helpful.
But just wanted to check if others had ideas.

Re: syntax change in velocity 1.7
Unfortunately, there is no introspection in Velocity.
One complicated idea would be to meta parse your template.
The idea would be to use a kind of Velocity introspection on all your templates.
Each time this introspection encounter a variable, like ${a} or a, you replace
it with a meta template that would content ${variableName} and would produce
${a}.
So, finally, it would do the job for you.
The only thing you need is that Velocity introspection but as far as I remember
it doesn't exist.

Re: syntax change in velocity 1.7
You can alter your templates to match the new syntax, something like:
find . -name *.vtl | xargs sed -ri -e
s/\\\$([a-z.\(\)]+)(\[[^\]+])/$\{\1\}\2/g
so that every reference which is followed by square brackets will be
enclosed in curly brackets.

Re: syntax change in velocity 1.7
Thanks, Claude,
That's probably what I'll end up doing. Either one time or possibly do it
dynamically in a custom resource loader.
(The problem is these files are all spread out in different accounts with
different authors and versioning).

Does velocity provide these features?
Hi there, i'm evaluating Velocity to find out whether it meets my requirements to generate text by using custom templates. I looked at the user guide and wrote a little hello world application but there are requirements for which I don't know if I have to write my own methods or if there are velocity tools that would do the job for me: Is there a way to automatically add line breaks when you merge the template with the context (without cutting words after e.g. 80 characters)? Is there a way to use text shifting (indentation) in combination with line breaks without cutting words after e.g. 80 characters)? Long text: $magic.doMagic( $text ) -- Long text: Some very Very long text, more text … Is there a way to automatically add line breaks (without cutting words after e.g. 80 characters) and add a certain String (e.g. 100. ) at the beginning of each line: Funny Velocity user request: $magic.doMagic2( $text ) -- Funny Velocity user request: this 100. is just a test, a test, a test, a 100. test, a test … Is there a way to cut the string of a variable after 9 characters and add a * to the string, if the string has more than 10 characters? #set( $test = textwithmorethan10char ) Test: $magic.doMagic3( $test) -- Test: textwithm* Thanx in advance! -- View this message in context: http://old.nabble.com/Does-velocity-provide-these-features--tp31748723p31748723.html Sent from the Velocity - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@velocity.apache.org For additional commands, e-mail: user-h...@velocity.apache.org

Natively, no, this is not the job of the velocity core. But it would be fairly simple to write a velocity tool that does that for you, similar to http://velocity.apache.org/tools/devel/javadoc/org/apache/velocity/tools/generic/DisplayTool.html DisplayTool does have a method for your last request, see http://velocity.apache.org/tools/devel/javadoc/org/apache/velocity/tools/generic/DisplayTool.html#truncate%28java.lang.Object,%20int,%20java.lang.String,%20boolean%29 You will have to enable the tools, then you would have to write: $displaytool.truncate($test, 10, '*', false) Alternatively, you can do that as well directly in the template, but it would be a bit harder since you don't have all the power of Java. For example, line numbering has been done in: https://github.com/xwiki/xwiki-platform/raw/master/xwiki-platform-core/xwiki-platform-web/src/main/webapp/templates/code.vm -- Sergiu Dumitriu http://purl.org/net/sergiu/ - To unsubscribe, e-mail: user-unsubscr...@velocity.apache.org For additional commands, e-mail: user-h...@velocity.apache.org
Re: Does velocity provide these features?
As Sergiu said, this is a job for tools and the DisplayTool that is part of the VelocityTools project supports only one of the listed features. However, if you have code or write code for the other features, those would be welcome as patches to the DisplayTool, as those are just the kind of thing that it does.

Well, i've got no problems getting Velocity to call public methods on instances of publicly declared classes. Got any more info you can share? Like the class in question? Velocity version?
