+Formatter Bytecode
+==================
+
+Background
+----------
+
+LLDB provides very rich customization options to display data types (see :doc:`/use/variable/`). To use custom data formatters, developers need to edit the global `~/.lldbinit` file to make sure they are found and loaded. In addition to this rather manual workflow, developers or library authors can ship ship data formatters with their code in a format that allows LLDB automatically find them and run them securely.
+
+An end-to-end example of such a workflow is the Swift `DebugDescription` macro (see https://www.swift.org/blog/announcing-swift-6/#debugging ) that translates Swift string interpolation into LLDB summary strings, and puts them into a `.lldbsummaries` section, where LLDB can find them.
