A Declarative Debugger for Sequential Erlang Programs

Declarative debuggers are semi-automatic debugging tools that abstract the execution details to focus on the program semantics. Erroneous computations are represented by suitable trees, which are traversed by asking questions to the user until a bug is found. This paper applies declarative debugging to the sequential subset of the language Erlang. The debugger takes the intermediate representat...

EDD: A Declarative Debugger for Sequential Erlang Programs

Declarative debuggers are semi-automatic debugging tools that abstract the execution details to focus on the program semantics. This paper presents a tool implementing this approach for the sequential subset of Erlang, a functional language with dynamic typing and strict evaluation. Given an erroneous computation, it first detects an erroneous function (either a “named” function or a lambda-abs...

A Declarative Debugger for Haskell

This thesis is about the design and implementation of a debugging tool which helps Haskell programmers understand why their programs do not work as intended. The traditional debugging technique of examining the program execution step-by-step, popular with imperative languages, is less suitable for Haskell because its unorthodox evaluation strategy is difficult to relate to the structure of the ...

A Declarative Debugger for Maude

Declarative debugging has been applied to many declarative programming paradigms; in this paper, a declarative debugger for rewriting logic specifications, embodied in the Maude language, is presented. Starting from an incorrect computation (a reduction, a type inference, or a rewrite), the debugger builds a tree representing this computation and guides the user through it to find a wrong state...
