NAME ^

Dotiac::DTL::Addon::json: Filters to generate JSON data

SYNOPSIS ^

Load from a Dotiac::DTL-template:

        {% load json %}

Load in Perl file for all templates:

        use Dotiac::DTL::Addon::json;

Then it can be used:

        {{ data|json|safe }}
        {{ data|json_ascii }}
        {{ data|json_pretty }}
        {{ data|json_pretty_ascii|safe }}

INSTALLATION ^

via CPAN:

        perl -MCPAN -e "install Dotiac::DTL::Addon::json"

or get it from https://sourceforge.net/project/showfiles.php?group_id=249411&package_id=306751, extract it and then run in the extracted folder:

        perl Makefile.PL
        make test
        make install

DESCRIPTION ^

This provides some filters to output any type of data

Filters

Like most other filters, these will return a safe value on safe input. But string literals are always safe and will produce bad output, so beware of those.

        {{ "Foo"|json }} {# "Foo" #}
        {{ "Foo"|json|escape }} {# "Foo" #}

json

Converts any value into JSON, even lists and dictionaries.

Output will be in UTF-8.

        data=>{List=>[1,2,3],Value=>"Foo\x{34fc}"};

        <a onclick="return {{ data|json }}"> 
        {# <a onclick="return {&quot;List&quot;:[1,2,3],&quot;Value&quot;:&quot;FooÒô+&quot;}"> #}
        
        var Value={{ data|json|safe }} 
        {# var Value={"List":[1,2,3],"Value":"FooÒô+"} #}

json_ascii

Like json, but the output will be in ascii. This is useful if the generated HTML page is not utf8.

        data=>{List=>[1,2,3],Value=>"Foo"};

        <a onclick="return {{ data|json_ascii }}"> 
        {# <a onclick="return {&quot;List&quot;:[1,2,3],&quot;Value&quot;:&quot;Foo\u34fc&quot;}"> #}
        
        var Value={{ data|json_ascii|safe }} 
        {# var Value={"List":[1,2,3],"Value":"Foo\u34fc"} #}

json_pretty

Like json, but with pretty output. This is much larger and mostly not needed.

        data=>{List=>[1,2,3],Value=>"Foo"};

        <a onclick="return {{ data|json_pretty }}"> 
        {# <a onclick="return {
          &quot;List&quot; : [
            1,
            2,
            3
          ],
          &quot;Value&quot; : &quot;FooÒô+&quot;
         }"> #}
        
        var Value={{ data|json_pretty|safe }} 
        {# var Value={
          "List" : [
            1,
            2,
            3
          ],
          "Value" : "FooÒô+"
        } #}

json_ascii_pretty

Like json_ascii, but also with pretty output. This is much larger and mostly not needed.

                data=>{List=>[1,2,3],Value=>"Foo"};

        <a onclick="return {{ data|json_ascii_pretty }}"> 
        {# <a onclick="return {
          &quot;List&quot; : [
            1,
            2,
            3
          ],
          &quot;Value&quot; : &quot;Foo\u34fc&quot;
         }"> #}
        
        var Value={{ data|json_ascii_pretty|safe }} 
        {# var Value={
          "List" : [
            1,
            2,
            3
          ],
          "Value" : "Foo\u34fc"
        } #}
