type checking for Hash values?

[mouhannad-sh]

I have a custom tag

{% tag name_1 | { default:  true } %}
{% tag name_2 | { default: "true" } %}

the definition I have is like this

parse(tagToken) {
      const { default: _default, ...rest } = Hash.parse(tagToken.args);
      this.defaultValue = _default;
	  console.log(_default) 
}

current output:

'true' 
'"true"'

expected

true // as boolean
"true" // as string

Am I doing something wrong? is there a better way to do this ?

Try Hash.create or Hash.createSync, what they do is parse and evaluate each expression. See: https://harttle.land/liquidjs/classes/_template_tag_hash_.hash.html

it seems to be exactly what I needed 🎉

I changed it to the following

async parse(tagToken, context) {
      const { default: _default, ...rest } = await Hash.create(tagToken.args, context);
      this.defaultValue = _default;
      console.log(_default, { type: typeof _default }); 
}

Input

{% tag name_1 | { default: true } %}
{% var name_2 | { default: "true" } %}
{% var name_3 | { default: '"true"' } %}

Output 🔥

true { type: 'boolean' }
true { type: 'string' }
"true" { type: 'string' }

many thanks !

@harttle it seems like Hash.create doesn't work anymore on the latest version (9.14.1) was working on 9.0.0

is it possible to achieve the same thing using the new API ?

thanks

It's still there but a bit different, I exported a toPromise (see the above commit) for ease of use.

const { Context, Hash, toPromise } = require('liquidjs')

const hash = new Hash('foo:bar')
const ctx = new Context({bar: 'BAR'})

// Outputs:
// { foo: 'BAR' }
toPromise(hash.render(ctx)).then(console.log)
// or `toValue` to render syncly
