[stringtemplate-interest] StringTemplate extensions

[Luis Leal]

Hi,

I've never needed "reverse", but I can see that it would be useful. I'd go
for <reverse(arg):{a|<a.type> <a.name>;}> - prefer the consistency.

Not sure what the use case was for "repeat" in the original post. I have
however needed to process items in a collection multiple times - mainly to
generate copies of pages when using StringTemplate to generate a PDF. It
doesn't seem optimal / elegant to have to modify the model just to process
items more than once? Maybe something like this?

$collection:{
$loopcounter:{
}$
}$

where loopcounter could be an attribute or a literal.

Interesting...could be useful.  I'm not opposed, but can anybody else
comment on the need? They certainly don't break the "rules".

I'm thinking that perhaps a more functional approach is what we want
for the order:

<args:{a|<a.type> <a.name>;}>

does them in order and to reverse, perhaps

<args:reverse():{a|<a.type> <a.name>;}>

or to be consistent with first(), rest() built-in functions,

<reverse(arg):{a|<a.type> <a.name>;}>

This one makes sense, right?

As for repeat, seems an option is the best

<"0"; repeat="20">

or

<initvalue; repeat="20">

Hmm...I'm uncomfortable with the notation a bit, but separator and
repeat seem similar enough to warrant another option.  Actually, you
are probably asking for this:

<initvalue; repeat="<n>">

or is it

<initvalue; repeat=n>

where n is an attribute saying how many times to do something.
Hmm...now my model-view separation alarm is going off.  Hmm...
