Chained else expression

[sunng87]

Support syntax

{{#if ...}}
{{else if ...}}
{{else}}
{{/if}}

handlebars-lang/handlebars.js#892

[golddranks]

Is there any workaround currently? I'd like to use this, but unfortunately I'm currently too busy to contribute.

[golddranks]

Oops the obvious workaround works. I had an unrelated syntax error because of a typo, which made me think that nesting wouldn't work.

{{#if var1}}
    ...
{{ else }}{{#if var2}}
    ...
{{ else }}
    ...
{{/if}}{{/if}}

[sunng87]

Yes.

To support chained else, we may need an update in current parser and helper definition because {{else if ...}} is incompatible with current model.

Hey @sunng87, any progress on this issue?

[sunng87]

@rousan sorry, there is no progress for now.

[rousan]

so, is there any way to add some patches like adding a block helper? It would very helpful then.

[sunng87]

@rousan the helper system is totally open. You can register you own block/inline helpers with our API. Checkout examples if you like.

For this chained else, some work needs to be done on the parser and our template structure to support chained inverse template segment. I will probably add support in future releases.
