swift_oss_helper.py

swift_oss_helper.py helps debugging Swift Standard Library using source code with Swift Toolchain distributed at swift.org.

This helps:

• Configuring target.source-map setting in lldb for adjusting symbol path lookup to distributed Swift Toolchain snapshots
• Processing *.swift.gyb without actual building Swift toolchain
• Generate Symbol Map at ~/Library/Developer/SymbolMap/uuids

Usage

1. install Swift Toolchain snapshot and symbols from https://swift.org/download/#snapshots
