Hi!
I'd like to use block parameters in my own helper. In my example scenario I want to add two values and "store" them as block variable "result" with a "let" helper (inspired by the ember.js let helper https://guides.emberjs.com/release/components/helper-functions/#toc_the-let-helper). Looking at the handlebars "with"-helper (https://github.com/handlebars-lang/handlebars.js/blob/master/lib/handlebars/helpers/with.js) I tried to create the following code where I expect result to be 3.
3
In my case this fails, but I can't figure out how blockParams works exactly and I could not find any lightncandy docs for it. I know that I could switch the context and just use {{.}}, but I hate the context switching feature and want to explicitely name the new I looked at the docs here https://zordius.github.io/HandlebarsCookbook/0022-blockhelper.html and here https://zordius.github.io/HandlebarsCookbook/9002-helperoptions.html .
Any help would be appreciated. Thanks!
$template = <<<EOF {{#let (add 1 2) as |result|}} Result is: {{result}} {{/let}} EOF; $phpStr = LightnCandy::compile($template, [ 'flags' => LightnCandy::FLAG_HANDLEBARS, 'helpers' => [ "add" => function ($a, $b) { return $a + $b; }, 'let' => function ($context, $options) { return $options['fn']($context, [ "data" => $options['data'], "blockParams" => [$context] ]); } ] ]);
