Set & Literals

[zeebo]

Add support for some kind of literal types like lists, dicts, numbers, and strings. The syntax for creating literals is still under debate, but they should be able to be used inside of if statements, and the new set statement, which would work like

{% set .some.path value %}

where value is some literal type, a call, or other path, overriding whatever was at that path value locally for the template (meaning it doesn't reach up into the caller of the Execute)

Need to work out how range works with this. For example say we have for a context

{"foo": {"bar": "bar"}}

and template

{% set .foo.baz "baz" %}
{% set .foo.bif "bif" %}
{% range .foo %}
    {% .key %}: {% .val %}
{% end range %}

do we get

bar: bar

or

bar: bar
baz: baz
bif: bif

as the output?

I feel like the latter output is what I would expect.

If I had an attribute I was adding to an item in the context, then iterating over it for display purposes, I'd expect to see it in that grouping. For example:

Context:

{
    "foo": {
        "name":     "thing 1",
        "deadline": "today"
    }
}

I'd expect to see tags on every page, with this:

{% if .foo.tags %}{% else %}
    {% set .foo.tags "none" %}
{% end if %}

<dl>
{% range .foo %}
    <dt>{% .key %}</dt>
    <dd>{% .val %}</dd>
{% end range %}
</dl>
