如何增加binding.pry周围的行数？

Question

使用gem pry-byebug，当我在某个地方添加binding.pry时，它只在我所在的行周围显示5行：

    157:       max_bytes: limits_config.max_read_bytes_per_parser,
    158:       max_reads: limits_config.max_reads_per_parser,
    159:       max_seeks: limits_config.max_seeks_per_parser
    160:     )
    161:
 => 162:     results = parsers.lazy.map do |parser|
    163:       # Reset all the read limits, per parser
    164:       limited_io.reset_limits!
    165:       read_limiter_under_cache.reset_limits!
    166:
    167:       # We need to rewind for each parser, anew

有没有办法增加这个数字以显示更多的代码行？

将whereami与指定要返回的行数的整数参数一起使用。

例如，给定文件foo.rb

# foo.rb

require 'pry'

def foo; end

def bar; end

def foobar
  # do something
  binding.pry
  # do something else
end

def baz; end

def foobarbaz; end

foobar

使用ruby foo.rb运行它

From: /Users/foo/foo.rb:11 Object#foobar:

     9: def foobar
    10:   # do something
 => 11:   binding.pry
    12:   # do something else
    13: end

⇒ 

并要求使用whereami 10查看+/- 10行

⇒ whereami 10

From: /Users/foo/foo.rb:11 Object#foobar:

     1: # foo.rb
     2:
     3: require 'pry'
     4:
     5: def foo; end
     6:
     7: def bar; end
     8:
     9: def foobar
    10:   # do something
 => 11:   binding.pry
    12:   # do something else
    13: end
    14:
    15: def baz; end
    16:
    17: def foobarbaz; end
    18:
    19: foobar

⇒ 

或者只使用whereami 1的两行周围代码

⇒ whereami 1

From: /Users/foo/foo.rb:11 Object#foobar:

    10:   # do something
 => 11:   binding.pry
    12:   # do something else
