Alpine.js x-for tuple syntax (item, index) falsely flagged as errors in HTML template

[Donghh0221]

Environment

• IDE: IntelliJ IDEA 2025.1.1.1
• Plugin: Alpine.js Support 0.7.0
• Project Type: Standard web project (HTML + Alpine.js)

Description

When using Alpine.js loop syntax with an index tuple, the IDE reports multiple false syntax errors on the (item, index) portion of an x-for directive. The template runs correctly in the browser; the issue is limited to editor parsing/highlighting.

Observed (all on the (item, index) segment)

• Variable name expected
• 'in' or ; expected
• Declaration expected
• Newline or semicolon expected

Expected

No errors; (item, index) in collection is valid Alpine.js syntax (documented).

Request

Please update the plugin parser to recognize Alpine.js tuple destructuring form (item, index) in list and suppress false error annotations.

i've the same issue after having double checked against https://alpinejs.dev/directives/for#accessing-indexes. function in the browser is okay. the filed errors are nasty as they are causing complaints during GIT commits.
