Implemented "output" event Refactored "seq" field generation Prevent debugging when editor and client are in different projects Removed unneeded references to peer on the parser Refactored way to detect project path Implemented "setBreakpoints" request Fix double events when terminating from client Refactored "stopped" event Implemented "stopped" with breakpoint event Implemented "stackTrace", "scopes" and "variables" request Report incoming number of stack dump variables Implemented proper reporting of scopes and variables from stack frames Prevent editor from grabbing focus when a DAP session is active Implemented "next" and "stepIn" requests Implemented "Source" checksum computing Switched expected errors from macros to silent guards Refactored message_id Respect client settings regarding lines/columns behavior Refactored nested DAP fields Implement reporting of "Members" and "Globals" scopes as well Fix error messages not being shown, and improved wrong path message
