A mustache-like template engine for Perl

text-caml's Issues

Sections remove traling line breaks

The following code removes the trailing line break after the section:

my $view = Text::Caml->new;
print $view->render_file('template', { abc => "Test" }) . "\n";

Template:

{{#abc}}
  This is a test.
{{/abc}}
ABC

The output is This is a test.ABC.
I would have expected a new line before ABC.
Am I wrong?

Thanks!

File::Path is missing from dependencies

Cannot set templates path via constructor

It does not seem to be possible to set the template path via the constructor. In line 36+37 the expression after unless may be incorrect:
currently:

$self->set_templates_path('.')
  unless $self->templates_path;

but should be:

$self->set_templates_path('.')
  unless $self->{templates_path};

i.e. the curly braces are missing. The workaround is of course to use the method set_template_path on the constructed object.

Whitespace Handling

I often like to use a space when writing partials and sections in Mustache templates in order to provide a resting spot for your eye:

{{# section}}
{{> partial}}
{{/ section}}

The Mustache spec shows that whitespace should indeed be ignored:

https://github.com/mustache/spec/blob/master/specs/partials.yml (starting line 104)
https://github.com/mustache/spec/blob/master/specs/sections.yml (starting line 252)

Iterating over hash keys

Let's consider the hash my %hash = ( foo => { a => 42, b => 43, c => 44 } );

It would be interesting to implement something that allows to iterate over hash keys

{{#hash.keys}}
    {{.}}
{{/hash}}

In case of more complex data we can still imaging using the same kind of syntax:

{{#hash.keys}}
    {{.}} {{name}} {{genre}}
{{/hash.keys}}

Or even a full nested hash support:

{{#animals.keys}}
    {{.}}:
    {{#mammal.keys}} 
        {{.}} -> {{name}}
    {{/mammal.keys
{{/hash.keys}}

What do you think?

Configurable default behaviour of HTML escaping

What do you think about adding configuration option to set default behavior as non-escaping? Some templates are used in HTML documents and current behavior is appropriate. But sometimes it's required to use templates for other types of documents.

'&' usage of course solves this issue but making non-escaping behavior default for such cases looks more handy.

my $view = Text::Caml->new(do_no_escape => 1);

'&' can be switcher in this case:

    my $do_not_escape = $self->{do_not_escape};
    if ($tag =~ s/\A \&//xms) {
        $do_not_escape = !$do_not_escape;
    }
