Rather than keeping state in the AST, which requires some gymnastics, we create a separate visitor flow which does the top down iteration necessary to calculate all of the state needed for proper whitespace control evaluation.
This is a breaking change for string mode users as there is no longer a distinct type for data parameters. Instead data consumers should look for the @ prefix value.
Allow the precompiler to generate source maps when the srcFile parameter is passed.
This refactors large chunks of the code generation pipeline, allowing metadata to be associated with code chunks as well as breaking out much of the code generation logic into a separate helper.
Allows for us to play nicely in environments such as Node that could have multiple versions of the library loaded. Also allows for implementors to provide their own behavior, provided they know what they are doing.
Fixes#886
This disables the standalone partial indent behavior required by the Mustache spec and allows for users to utilize partials in the same manner as under 1.x.
Fixes#858
Allows users to chain multiple helpers together using their inverse callbacks. I.e.
```
{{#if foo}}
{{else if bar}}
{{else}}
{{/if}}
```
The control flow here effectively causes the helpers to be nested. The above is actually syntactic sugar for this:
```
{{#if foo}}
{{else}}
{{#if bar}}
{{else}}
{{/if}}
{{/if}}
```
Any helper may be used in this manner, the only requirement is they support normal calls and inverse calls.
Introduces a breaking change in that `{{else foo}}` may no longer be used as a root level operator. Instead `{{^foo}}` must be used.
Fixes#72.
We already have to track these behaviors for the standalone parsing and rather than having two whitespace pruning implementations this moves all of the behavior into one place.
Fixes#852
