Support for Handlebars 3.0.0

[saamalik]

Hi,
Handlebars 3.0.3 is out. Will the latest version of Handlebars receive any love? =)

it is already there:

Handlebars hbs = new Handlebars();

hbs.handlebarsJsFile("/handlebars-v3.0.3.js");

Just download handlebars-v3.0.3.js and add it to the root of your classpath

That's cool-- any plans to make 3.0.0 the new default for handlebars-maven-plugin? So we don't have to download and maintain our own copy?

[jknack]

yea, 3.0.0 will be the new default once handlebars.java 3.0.0 gets out!

but there is no release date yet... I'm busy working on http://jooby.org which I invited you to try and play :)

maybe straight to 4.x ? :)

+1 for 4.x support. Your embedded ANTLr grammar doesn't appear to support the block syntax for partials which was added (the error message isn't fantastic either; I thought I was using the wrong handlebars.js file at first and didn't realize the error was actually coming from inside the Maven plugin itself).

Hi guys, can you collect what are the new feature of handlebars.js 4.x? For example, I don't know what is: block syntax for partials.

Thanks

If you reference http://handlebarsjs.com/partials.html, one of the new features is the ability to supply fallback / additional content to a partial by invoking it in "block" form, like so:

The normal behavior when attempting to render a partial that is not found is for the implementation to throw an error. If failover is desired instead, partials may be called using the block syntax.

{{#> myPartial }}
  Failover content
{{/myPartial}}

Which will render Failover content if the myPartial partial is not registered.
This block syntax may also be used to pass templates to the partial, which can be executed by the specially named partial, @partial-block. A template of

{{#> layout }}
  My Content
{{/layout}}

with the layout partial containing

Site Content
{{> @partial-block }}

Would render

Site Content
My Content

It also seems like support for partial variables doesn't work either? I get different results compiling with handlebars from npm when using a construct like:

{{> myPartial foo="bar"}}

If I'm interpreting handlebars-lang/handlebars.js#410 correctly this was actually added back in the 2.x release line.

[jknack]

partial params does work! do you have problem with handlebar.js integration ?

[tgolden-andplus]

Hrm, perhaps my configuration of the Maven plugin is wrong then? I'm telling it to use the 3.0.3 handlebars.js file, but my outputted templates.js file does not include the proper hash params. I'll see if I can put together a self-contained test case.

handlebars.java 3.0.0 will comes with handlebars.js 3.0.0 as default
