[Freemarker-devel] Currency w/ out currency symbol

Post by Andy Zeneski
Looking for a way to format a currency for an input box. So the currency
symbol should not be shown.
So, what I want is ${price?string.currency?substring(1)}
Any suggestions?

In the latest CVS, you could make this a function:

<#function mycurrency value>
<#return value?string.currency?substring(1)>
</#function>

${mycurrency(price)}

Of course you could just write a method in Java to do the same thing,
and put it into your model.

If you don't care about locale, you can just hard-code the format:
${price?string("0.00")}

Is there a ?substring built-in? Didn't show up as valid in eclipse.

No, but you can use operator: str[first..last]

What if I don't know what last is? I need str[1..]

Actually what I am doing is price?string.currency[1..?]
price?string.currency[1..price?length] does not work due to the fact that
the trailing 0 is not there if price = 3.4

Yea, well that's a pain in the butt, needs to be a one liner. should add a
[1..*]

Sorry, you'll need to do something like
<#function mycurrency value>
<#local value = value?string.currency>
<#return value[1 .. value?length - 1]>
</#function>
${mycurrency(4.2)}
prints "4.20" in my locale. (I tested this time...)

I'm not against that, though it might give the parser fits.

FWIW this will also work ;-)

${price?string.currency?replace("$","")}

But only if I know the symbol.. can I do a replace index?

Well, if you want to be really country independent, then substring(1)
would not work either. For example, we write currency amounts as this:
123 Ft

You are correct and I think that formatting ##0.00 should do the trick. It
appears that the decimal is locale aware so it should be all good.

No...
BTW, [1..*]. I think that the introduction of [x..y] as sub-string
operator was a mistake. So I'm not too enthusiastic to continue on this
line. Maybe it would be better to introduce ?substring(x[, y]) then...
I'm not sure.

I guess ${price?string("##0.00")} should do the trick...

Wow. I like this syntax. I'm +1 on supporting it.

I don't understand why does it use "*". Shouldn't it be rather [1..]?

And BTW, if it works for strings, then it has to work with sequences as
well.

I only suggested a '*' so you would know what I meant. Any character would
do, or even no character like what Daniel suggested. It would be very useful
for sequences too.

Well, if it works for strings, we'll have it work for sequences for sure.

I think it might be better just from a pure parser POV to use an
elipsis, i.e. 3 dots.

myString[3...]

Not very hard to do, and probably desirable, though we're rather busy
with some other things right now.
