[stringtemplate-interest] [RE:] Re: i0 with alternating templates

[Daniel Brenner]

Interessting: I would have expected that i and i0 are available in each loop and not only in anonymous templates. What is the reason for this? (for me this makes no sence... so far)

Anyway: thanks a lot!

Cheers,

- Daniel

Wrapping the template calls into anonymous templates will give you access to i and i0. 


In your example it may look like this: 


$results:{$resultlistOddRow(i, someVar)$}, {$resultlistEvenRow(i, someVar)$}$


With the templates resultlistOddRow  and resultlistEvenRow  defined like this:


resultlistOddRow(nr,p) ::= "$nr$. $p$ (odd)$\n$"
resultlistEvenRow(nr,p) ::= "$nr$. $p$ (even)$\n$"


and 
results: [A, B, C, D]
someVar: x


ST4 will render:


1. x (odd)
2. x (even)
3. x (odd)
4. x (even)

Hi,

I have a table with results that was build using alternating templates. The following lines is used for this:

$results:resultlistOddRow(somevar), resultlistEvenRow(somevar)$

How can I number the rows? In the templates resultlistOddRow and resultlistEvenRow I tried to access $i$ and $i0$ but stringtemplate keeps telling me "implicitly-defined attribute i not visible" and "implicitly-defined attribute i0 not visible".

Any ideas?

Cheers,
