I have a code like this. This code is not formatted very well. I tried to add support for set tag. I don't know how i write a test for this and i don't find a document section for this.

{% set schema=[
{
"name": "id",
"type": "integer",
"primary": true
},
{
"name": "name",
"type": "string"
}
] %}

Now, code formatted like this:

{% set schema=[
    {
        "name": "id",
        "type": "integer",
        "primary": true
    },
    {
        "name": "name",
        "type": "string"
    }
] %}

@ahmetelgun I expanded this a bit more - it will now also try to clean up the value of set. I added json5 library to parse javascript style json (single or no quotes on keys and values).

• if it is json then the json will be formatted w/ python's json.dump. With this we can indent the json if the line becomes too long.

• if the value is a list of tuples we can can use python eval to cleanup whitepsace and quotes... no line length formatting tho
  some fancy logic could be added for that one day

• otherwise it will leave the formatting as-is... for example, if the json is invalid etc.

I added tests in the nunjucks > test_set folder.

Thanks a bunch for this!

closes #287
closes #518
fixes 1/2 of #370 (still no function formatting)

json keys that don't require quoting in javascript will not be quoted here. Does that work in your case as well?

looks like I accendently snuck in another change here that fixes some html tags getting formatted inside script tags.
