Radu Cotescu created SLING-8860:
-----------------------------------
Summary: Issue a warning when data-sly-test is passed a constant
value for evaluation
Key: SLING-8860
URL: https://issues.apache.org/jira/browse/SLING-8860
Project: Sling
Issue Type: Improvement
Components: Scripting
Reporter: Radu Cotescu
Assignee: Radu Cotescu
Fix For: HTL Compiler 1.2.2-1.4.0, HTL Maven Plugin 1.3.2-1.4.0
The {{data-sly-test}} plugin should issue a warning every time it's passed a
constant value (including an empty expression which translated into a
{{NullLiteral}}) or a concatenation operation for evaluation - the former is
redundant, whereas the latter doesn't make sense and could potentially be a
typo:
{code:html}
<!-- Examples that should generate warnings-->
<span data-sly-test="${0}">if true</span> <!-- number literal -->
<span data-sly-test="${'a'}">if true</span> <!-- string literal -->
<span data-sly-test="${}">if true</span> <!-- empty expression, null literal -->
<span data-sly-test="${[1, 2, 3]}">if true</span> <!-- array literal -->
<span data-sly-test="${properties}}">if true</span> <!-- concatenation -->
{code}
