implement raw

[panosru]

Hi, as I see {% raw %} is not implemented, I tried to use angular js which uses {{ }} as well so I realized that raw is not there :/

Any workaround for that?

[ceymard]

Nope, have to implement it.

[panosru]

if you guide me a little bit because I don't feel quite comfortable with Coco I could implement it :)

@ceymard from what I saw, the @child_node.compile method need to be modified in order to return raw string and not compiled but I can't find the compile method.

I was thinking for something like that:

/**
 * Raw Node
 */
class NodeRaw extends NodeTagContainer
    @tag = \raw
    @until = \endraw

    (specs) ->
        super ...

    compile : function (opts, ctx)
        return @child_code opts, ctx

Where the true in third parameter will indicate that we need raw output.

I really struggled a lot by trying to make raw node work, from what I understood the template engine compiles the template and breaks it into nodes, once this step happens then nodes take place but in case you want to have a raw node you have to change the compilation process, am I right? Is there any other easier way to have raw node?

Thanks

After lots of hours I gave up on this...

I ended up altering advance method from lexer.co file:

    advance: function (to_position)
        res = @input.slice @position, to_position
        @position = to_position

        _res = res.trim()

        if NodeRaw.tag is _res
            @_raw_enable++
        if NodeRaw.until is _res
            @_raw_str = @_raw_str.substr(0, @_raw_str.length - 2)
            @_raw_enable = -5

        if 3 < @_raw_enable
            @_raw_str += res
        else if 1 <= @_raw_enable or @_raw_enable < 0
            @_raw_enable++

        if 4 > @_raw_enable and @_raw_enable >= -4
            if 0 < @_raw_str.length
                res = @_raw_str
                @_raw_str = ''

            switch @_raw_enable
                case -3
                    res = '{%'
                case -2
                    res = " #{NodeRaw.until} "
                case -1
                    res = "%}"
            return res
        else
            return ''

So this tpl

=====================

{% raw %}
  {% for name in ['foo', 'bar'] -%}
    Hello {{name}}!
  {% endfor %}
{% endraw %}

{% if true %}Yeah!!!{% endif %}

result into this:

=====================

  {% for name in ['foo', 'bar'] -%}
    Hello {{name}}!
  {% endfor %}
Yeah!!!

but this:

=====================

{% raw %}{% for name in ['foo', 'bar'] -%}Hello {{name}}!{% endfor %}{% endraw %}

{% if true %}Yeah!!!{% endif %}

result into this:

=====================

 for name in ['foo', 'bar'] -%}Hello {{name}}!{% endfor %}Yeah!!!

:(

Well, no, this is exactly it.
