$idx and $len
|
|
-------------
|
|
|
|
$idx and $len do not survive through an explicit context setting, which will work perfectly with my injected-context architecture.
|
|
|
|
You can use $idx and $len as your explicit context, but as scalar values I do not think there is a way to access them anyway.
|
|
|
|
Exists and Not-Exists
|
|
=====================
|
|
|
|
Looks like you can exlicitly set a context with exists and not-exists tags too. This works out well in the parser because I am using the same code for those blocks.
|
|
|
|
Partials
|
|
--------
|
|
|
|
Explicitly setting a context in a partial also works. The explicit context takes priority over the parameters in the partial tag.
|
|
|
|
This works for both regular named partials and quoted partials.
|
|
|
|
While normally parameters are injected 1 level above the current context, if both parameters and explicit are set, they are injected below the current context. So if the context tree was `1->2->3`, with just parameters you'd have `1->2->parameters->3` but with an explicit context you have `parameters->explicit`.

|
|
Helpers
|
|
-------
|
|
|
|
Explicitly setting a context in a helper works too.
|
|
|
|
Blocks and Inline Partials
|
|
--------------------------
|
|
|
|
Explicitly setting a context on an inline partial does not work, but it does not error out either, so I need to add support for this in the parser.
|
|
|
|
Explicitly setting a context on a block does work.
|
|
|
|
The explicit context for inline partials is evaluated in the context for that template file containing the block, not the inline partial (so, whatever the context is when we invoke the partial containing the block).
|
|
|
|
References
|
|
----------
|
|
|
|
Explicitly setting a context does not work on a reference, but it has revealed that invalid dust is rendered verbatim. I'm going to leave that commented out until I can address that in a later branch.
|
|
|
|
Paths
|
|
-----
|
|
|
|
Explicit contexts do support deep paths.
|
|
|
|
Else Blocks
|
|
-----------
|
|
|
|
Else blocks also use an explicit context.
|
|
|
|
Complete Failure
|
|
----------------
|
|
|
|
If the walk destination does not exist, and the explicit context does not exist, then you end up with absolutely no context.
|
|
|
|
Regular Path Failure
|
|
--------------------
|
|
|
|
If the regular path fails but the explicit path succeeds then the context is set to the explicit path.
|
|
|
|
Falsey Explicit Path
|
|
--------------------
|
|
|
|
Since dust would not walk to a falsey path, theres no difference between a falsey path and a non-existent path.
