Laravel DB SQL Highlighting

Adds SQL syntax highlighting to raw SQL strings passed directly to Laravel's DB facade in PHP files.

The extension is declarative: it injects VS Code's built-in SQL TextMate grammar into recognised PHP strings and does not run any extension code.

Supported calls

DB::select()
DB::selectOne()
DB::selectResultSets()
DB::scalar()
DB::insert()
DB::update()
DB::delete()
DB::statement()
DB::affectingStatement()
DB::unprepared()
DB::raw()

Leading namespace paths are supported, including \DB and \Illuminate\Support\Facades\DB.

Single-quoted PHP strings are also supported. PHP variables in double-quoted queries retain PHP variable highlighting.

Scope

The SQL must be a quoted string passed directly to a supported method. A lexical grammar cannot follow variables, so this form is not highlighted:

$query = 'SELECT * FROM users';
$rows = DB::select($query);

Concatenated expressions outside the initial SQL string continue to use normal PHP highlighting.
