I have the same issue?

[chaliy]

Not sure I understand. Could you please provide an example?

@chaliy Example is using handlebars-intl library and adding other custom javascript directives ..

I would recommend using default _preview_handlebars.js which allows us to include custom javascript with dependent modules.

Hello, chaliy!

Thanks for plug-in.
Custom helpers support needed.
Can you add some option to add JS file with helpers to handle code like:

  {{#compare @key "==" "NONE"}}
    <p>Some text here for NONE</p>
  {{/compare}}

...
and many other cases like:

If no one's looking at this, might try implementing when I get some time. I'm thinking, along with the my-file.hbs.json file, the helper functions can be defined in my-file.hbs.js

See PR #9

This would be very useful for us. We're trying to use this for working with our templates which are using custom helper functions, and are otherwise blocked by not being able to add the functions in the extension.

I see that there is a PR above, but it was never merged and is now out of date. Will this ever be a feature?

Hey @DanTalash, can you try if my version of the extension works for you? https://marketplace.visualstudio.com/items?itemName=anonimitoraf.handlebars-preview-with-function-support

Hi @anonimitoraf,

I tried switching to your version of the extension. It took a few attempts, but I was able to finally stop the preview throwing errors for our functions. Thank you, this should be useful.

I will try using it to see if there are other blocking issues, but my first note would be that the preview doesn't seem to auto-refresh. I need to close and reopen it to see any changes reflected. I would make an issue on your repo, but it doesn't appear that issues are enabled.

If you need something that works right now, you may want to take a look at this alternative. I tried it and it works quite well.
