@filipenevola Seems to be an error with CircleCI configuration? |

Yes @nathan-muir, they were using CircleCI 1.0 which was deprecated. You can see new tests being created here |

Hi, tests are fixed on |
As HTML.TransformingVisitor would not visit the elements within each block tag, the OptimisingVisitor would skip a portion of the templates.
Resolves an issue where RawCompactingVisitor would not recurse through any nested elements.
Currently all optimisation within tables is avoided. Even for nested elements.
This prevents optimisation of <table> and <tr> elements, but allows all children of those elements to be optimised.

Hi, (@filipenevola reopening #279)
Found a few instances where the spacebars compiler aborts optimisations unnecessarily.
Case 1: Inside Block tags, eg
{{#if }} ... {{else}} ... {{/if}}Case 2: More than one level of nested elements. (Compacting
HTML.Rawfails)Case 3: Inside
<tables>(caused by a pessimistic workaround to auto-injection of<tbody>when usinginnerHTML.)The resolution for Case 1 turned out messier than I had hoped. Due to block tags like
{{#markdown}}that don't contain HTML. Rather than exposing thetextModeprop, maybe something likeisHTML?My motivation for digging through this code, is to implement a
<template whitespace="strip">mode [1]. Which would work similar to react (Strip any whitespace that contains a newline).Early comparisons show that this saves around ~100kb (uncompressed) from my client bundle.
