in reply to Dancer Arrayref to Template

By default, Dancer uses a simple templating system that has syntax that is very similar to Template::Toolkit. However, you can only pass scalars and you don't have other control stuff (like if statements, loops, etc.). If you try to pass an array or hash to the template with the default templating system choice, the variable in the template will only have the array reference or hash reference.

In order to use Template::Toolkit, you need to have template: template_toolkit in your config.yml file or set template => 'template_toolkit'; in your code itself. Look at the Dancer::Config, Dancer::Template and Dancer::Template::Simple documentation for more details.

[ovedpo15]: another question about regex. if I have a string like this: "a/b/,c/d/e,5" I would like to remove the string after the last comma so the output will be "a/b/,c/d/e" how to do so?
[Corion]: ovedpo15: You could split on comma, and then join everything together, except the last part. Or you could match and make sure that the last part has no comma, like qr!,[^,]+$!, or you could use rindex.
[ovedpo15]: But I don't know the length of the string. will it still work?
