we know this #set($a = $a + 1) will change $a which in some cases may not be preferable...but thanks anyway. 2009/7/20 Alexander > Hi, > > Use > > #set($a = $a + 1) [?] > > > Correct me if Im wrong but if u use variable like this it would write > "hello" on a single line, where is the problem? [?

RE: simple problem

Hi, Use $velocityCount in place where you need incremental value of some variable Eg: instead of, #set($a = 0) #foreach($mapping in $mappings) Do something.. #set($a = $a+1) Type something Do it like: #foreach($mapping in $mappings) Do something.. Type something $

Re: simple problem

thanks Rupali, I got this problem when I started to think that, can I simply output an expression like #{1+2+20*3+$a} without a varible? 2009/7/20 Rupali Gupta > Hi, > > > > Use $velocityCount in place where you need incremental value of some > variable > > Eg: instead of, > > > > #set($a

Re: simple problem

Hello,everyone,I work on the problem this whole afternoon... finally,I decided to end this with a macro: #macro(expr $expression) #set($temp--='#set($temp---'+"=$expression)"+'$temp---') #evaluate($temp--) $temp--- #end #set($a=2) #expr("$a*100+200") which result in a 400. wait for an easier way f

Re: simple problem

Yeah, but $velocityCount starts counting from 1 not from 0, don't it? Tricky moment so. 2009/7/20 Rupali Gupta > Hi, > > > > Use $velocityCount in place where you need incremental value of some > variable > > Eg: instead of, > > > > #set($a = 0) > > #foreach($mapping in $mappings) > > Do someth

Re: simple problem

Maybe you should find some class that can parse and evaluate math string (like "1+2+3*3 + 8/2") andthen use it in macro? #macro(calc $expr) $mathHelper.calculate($expr) #end I see you are trying to write ur own parser and I dont think It is a good idea. There should be a lot of such classes in in

Re: simple problem

I mean that always people say that you could use it in foreach statement and gives completely incorrect example as we saw there. So I tried to stress that initial value default is 1 not 0. Sure javadev can figure it out, but with wrong example in front of eyes it would be mentally harder. 2009/7/20

Re: simple problem

Yes,Alexander,and I google it,and i found one choice:jep.and maybe javacc is another choice for this. by the way,besides evaluating math expression ,my macro can insert varibles in it. like expr("$a+100*$b"). still I think this is not a good way to do it,maybe next version of velocity will support

Re: simple problem

hello,try it this way,with single quote, #expr('$a+$b*300') which works as expected. 2009/7/20 Alexander > lanxiazhi, > > > > by the way,besides evaluating math expression ,my macro can insert > > varibles in it. > > like expr("$a+100*$b"). > > > Before you passing "$a + 100*$b" to method param

Re: simple problem

I meant passing such string without single quote to method as parameter eventually leads to same result: variables replaced with values and expression calculated. But using some math helper class is more flexible than writing your own macros. 2009/7/20 lanxiazhi > hello,try it this way,with sing

Re: simple problem

ok,you're right,now i got what you mean. just a moment ago,I realized that I need no such math helper or such compicated macro as I wrote at all.If I have a velocity tool class called Simple,which contains a method : double f(double d) {return d}; then I can use it in the template:$Simple.f($a+100*

Also, the Tools 2.0 documentation seems written from the point of view that you're upgrading from Tools 1.4. Since I don't currently configure or use the Tools, I seem to be missing some key concepts. I can't find the Tools 1.4 documentation. Steve Cohen wrote: Thanks. This sounds like the

Thanks. This sounds like the right way to go, yet I currently have a nice simple configuration based on 1.4. The $esc.hash seems to be a 2.0 thing. I don't use the tools now and it seems like a fairly heavy-duty upgrade to fix such a small problem, involving configuration files, etc. that I

Okay, I wrote too soon. I now see the escape tool and its hash method in tools 1.4. My bad. I still don't understand what, if anything, I need to do to configure my application to use it. My present configuation is done entirely in Java: private void init(ServletContext ctx) throws Vel

Okay, I found THIS: http://www.mailinglistarchive.com/velocity-u...@jakarta.apache.org/msg00552.html and it works, but I'd still rather load the tool at the time the Engine is initialized, rather than have to put it in the context everywhere I want to use it. So what I'm really looking for is

Re: Escaping question

In VelocityTools 1.4, there is little support for auto-loading GenericTools, i wouldn't bother. Just create a context, add tool instances that you want and then use the already available context-chaining support in VelocityContext to use that "tool" context as a base context for other ones. In Ve

Re: Escaping question

Thanks, Nathan. Although your single-quoting thing is the right answer for this particular situation, this discussion did at least get me thinking about the Tools, which I haven't used before. They could provide some value for me in other situations so it's good to learn about them. Therefor

Re: AW: getEncodingFromStream from UnicodeInputStream

I think you misunderstood a fundametal reason of the UnicodeInputStream class. It is to use so that template loaders don't need to tell an encoding so all is fully transparent. getTemplate(name, encoding) method is an old legacy method where we as a user must know the encoding beforehand. This
