/Erlang 21

1 Introduction

1.1 Scope

Debugger is a graphical user interface for the Erlang interpreter, which can be used for debugging and testing of Erlang programs. For example, breakpoints can be set, code can be single-stepped and variable values can be displayed and changed.

The Erlang interpreter can also be accessed through the interface module int(3).


Debugger might at some point start tracing on the processes that execute the interpreted code. This means that a conflict occurs if tracing by other means is started on any of these processes.

1.2 Prerequisites

It is assumed that the reader is familiar with the Erlang programming language.

Modules to be debugged must include debug information, for example, erlc +debug_info MODULE.erl.
