如何增加装订周围的行数撬

Question

使用gempry-byebug，当我在某个地方添加binding.pry时，它只显示我所在行周围的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来显示更多的代码行？

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

From: /Users/foo/foo.rb:11 Object#foobar:
9: def foobar
10:   # do something
=> 11:   binding.pry
12:   # do something else
13: end
⇒ 

并要求查看带有whereami 10:的+/-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
⇒ 

或者只是两条带有whereami 1:的周围线路

⇒ whereami 1
From: /Users/foo/foo.rb:11 Object#foobar:
10:   # do something
=> 11:   binding.pry
12:   # do something else
⇒
