摘要

代码组合很容易出错，因为它对程序员的认知过程提出了严格的要求。在这个阶段，程序员可以从机器的帮助中获益，但传统的编程环境在这个阶段基本上是被动的。通常的假设是，程序员在输入整个例程后进行调试，尽管此时他/她对某些细节的记忆可能已经衰退。我们建议，如果在输入语句后立即执行语句，并显示新的程序状态，则可以提高编码效率。程序员可以看到语句是否有预期的效果，并在思考它的时候纠正它。我们已经实现并非正式地测试了这个“提前调试”特性的原型。我们发现，与传统环境相比，用户在代码输入过程中修复了更多的bug，生成的代码更快，错误更少，并报告说使用后者就像“在黑暗中编程”。

Ahead-of-time debugging, or programming not in the dark

Code composition is error-prone because it places severe demands on the programmer's cognitive processes. The programmer could benefit from the machine's help at this stage, but conventional programming environments are essentially passive then. The usual assumption is that the programmer does debugging after entering a whole routine, although by this time his/her memory of some details may have decayed. We propose that coding efficiency would be improved if, as soon as a statement is typed, it is executed, and the new program state is displayed. The programmer can see whether the statement has the intended effects, and correct it while the thinking for it is still fresh. We have implemented and informally tested a prototype of this "ahead-of-time debugging" feature. We found that users fix more bugs during code entry and produce code faster and with fewer errors, compared with a conventional environment and report that using the latter is like "programming in the dark".
