Overview

Nests hyphenated data-* / aria-* keys so every key is a 1.9 identifier. Rails and Haml flatten the nested hashes back to the same HTML (data-game-live-target, aria-label).

This is not a HashSyntax replacement. HashSyntax still owns : vs =>. Nesting first is what lets HashSyntax stay in ruby19 form instead of mixed rockets or quoted-symbol keys.

Keys whose hyphen segments are not identifiers (1p-ignore) stay. Real HTML attributes (http-equiv) stay. Stimulus controller names are not renamed — hyphens split in place.

Examples:

# bad
{ data: { controller: 'chat', 'chat-target' => 'input' } }
{ 'aria-label' => placeholder }

# good
{ data: { controller: 'chat', chat: { target: 'input' } } }
{ aria: { label: placeholder } }
