Re: Format and Join an Array in a Template

It looks like you want to do the same thing to each item in the list except the last item, right? I think:

[% FOREACH n in names.slice(0,-2) %]  
.[% n %]([% n %]),
[%- END %]
.[% names.last %]([% names.last %])

Would do what you want. See Template::Manual::VMethods for more. The above is untested, so play around until it actually works.

Update: s/slice(0,-1)/slice(0,-2)/

It fails if the list has zero elements. It's getting complicated fast, which is why I didn't post that solution.	[reply]

Thanks, this works (with `.slice(0,-2)`). I was simply thinking the wrong way. The fact that the format must be used twice is a little drawback, but I think it does not get much shorter. It is a pity that the Template module does not provide a 'map' virtual method, otherwise a 'list.map(...).join(...)' would be possible.	[reply] [d/l]

The fact that the format must be used twice is a little drawback, You could use a `[% BLOCK %]` to remove the redundancy.	[reply] [d/l]
