Overview

Searches JS/JSX/TS/TSX files in the workspace for definitions of a named JavaScript global (variable, function, class, or window property assignment).

Delegates subprocess execution to CodeSearchService (rg/git grep/grep).

Ranking: top-level declarations (column 0, window.X =, or export) are Sprockets globals and sort before nested/indented matches, so go-to- definition prefers the global over a same-named function buried inside an IIFE. When parent is given (the user clicked Parent.myFunction or a name destructured from Parent), member definitions are resolved first.

Returns an array of hashes:

{ file: String, line: Integer, snippet: String, topLevel: Boolean }

Member results additionally carry member: true.

SCAN_CAP =

Matches parsed before ranking. The cap must be applied AFTER sorting or a flood of nested matches could crowd the top-level definition out.
