Ruby 检查可读性? [英] Ruby Inspect readability?

问题描述

有没有办法让inspect的输出更具可读性?

Is there a way to make the output of inspect more readable?

在 Perl 中，有 Data::Dumper 使输出更易于阅读.

In Perl, there is Data::Dumper which makes the output more easy to read.

推荐答案

ruby 标准库包含 PP(Pretty Print"的缩写)，它的结构格式比标准检查要好得多:

The ruby standard library contains PP (short for "Pretty Print"), which formats structures much better than the standard inspect:

http://www.ruby-doc.org/stdlib/libdoc/pp/rdoc/index.html

您需要在源文件顶部require 'pp' 才能使用它，然后将p obj 替换为pp obj 在您的代码中.

You need to require 'pp' at the top of your source file before you can use it, and then just replace p obj with pp obj in your code.

我发现它特别适用于散列和数组！

I find it really useful for hashes and arrays in particular!
