WhatsApp/edb

This system is an Erlang debugger (EDB) that provides core debugging capabilities such as line and function breakpoints, step execution, and stack frame inspection. It extends these features with a Debug Adapter Protocol (DAP) implementation, allowing external IDEs to connect and debug Erlang nodes, including support for multi-node clusters. The project is structured as a rebar3 umbrella application and includes comprehensive test suites to verify its attachment, evaluation, and breakpoint functionalities.

Adds a new Debug Adapter Protocol (DAP) implementation to the Erlang debugger, enabling IDEs and editors to connect to and debug Erlang nodes. This includes modules for encoding/decoding DAP messages, handling standard requests (launch, attach, continue, disconnect, evaluate, breakpoints, etc.), managing session events (initialized, stopped, output, terminated), and parsing request arguments. It also introduces a configurable language module system with a default Erlang implementation to map source files to modules for breakpoint resolution.

A new rebar3 plugin, \prepare\_edb\_tests\, has been added to automate test setup for the edb application. When invoked via \rebar3 prepare\_edb\_tests\, it locates the compiled \edb\ binary and copies it into the \\_data\ subdirectories of all discovered test suites within the \test\ directory, ensuring the binary is available for test execution.

The \src\ directory's Erlang debugger (\edb\) and its Debug Adapter Protocol (DAP) implementation (\edb\_dap\) have been completely removed. This eliminates the ability to attach to Erlang nodes, set breakpoints, step through code, and inspect stack frames via the DAP interface.

The edb application now includes a rebar.config file that registers pre-build hooks for Common Test (ct). Specifically, it configures the system to escriptize tests and run a custom prepare\_edb\_tests step before test execution, ensuring that test dependencies are correctly handled during the build process.

The project is restructured into an umbrella layout with separate \edb\ and \edb\core\ applications, updating the \rebar.config\ to reflect the new \apps/\\ directory structure for formatting and dependencies. The custom Erlang/OTP fork, previously managed as a git submodule, is removed, and the minimum required OTP version is raised to 27. Additionally, the \warn\_export\_vars\ compiler warning is disabled, the \assert\ testing library is added to the test profile, and documentation generation is switched to \ex\_doc\ with the DAP guide included as an extra.

The edb debugger now supports function-level breakpoints in addition to existing line breakpoints, allowing users to pause execution when specific module/function/arity combinations are called. The debugger also supports multi-node debugging, enabling reverse attachments to child nodes and managing breakpoints across a cluster. Internally, the project has been restructured into a standard rebar3 umbrella layout (files moved to apps/edb\_core/src), and the bootstrap process now allows injecting custom code into child nodes via ERL\_AFLAGS.
