ArrayList<String> / mustache output

[Bobo]

Hi,

I'm providing to mustache an Hashmap containg a key "myArray" associated to an ArrayList that contains only String values ["one","two","three"].

When I use such template {{myArray}}, java mustach output value is [one,two,three]. The double quotes are not anymore present... I'm expecting such result... ["one","two","three"].

Thank in advance for your help

Bobo

PS : I'm trying to create a template that output the element of this list with not trailing comma...

When you use {{myArray}} it is just using the default toString() method on ArrayList. That method doesn't put quotes around the elements.

Thanks for your help.

Actually, I'm trying to generate such output ["one","two","three"]... but didn't yet find a solution.

Iterating on each element of the list with such template : '"{{.}}" ,' will lead to a trailing comma..

It is fairly ugly in mustache for this kind of thing as it works much better with HTML and the like where the last token isn't special. There is a class included with mustache.java called "DecoratedCollection" that gives you first/last/index that would help you in this case. Here is a test case that shows how it is used:

https://github.com/spullara/mustache.java/blob/master/compiler/src/test/java/com/github/mustachejava/util/DecoratedCollectionTest.java

{{#myArray}}{{#first}}[{{/first}}{{^first}}, {{/first}}{{value}}{{#last}}]{{/last}}{{/myArray}}

I added a test that shows how it would work in your case.
