Linux 我的文本文件的 cat 和 less 输出与 gedit 和其他 gnome 编辑器不同

Question

我将 ri 的 ruby 数组文档重定向到一个文件中，但它在 gedit 中看起来不太好。但是文本在 cli 中看起来很好。这就是我的文件在终端编辑器中的样子。这里一切都很好

= Array#to_param

(from gem activesupport-5.1.3)
------------------------------------------------------------------------------
  to_param()

------------------------------------------------------------------------------

Calls to_param on all its elements and joins the result with slashes. This is
used by url_for in Action Pack.


= Array#to_query

(from gem activesupport-5.1.3)
------------------------------------------------------------------------------
  to_query(key)

------------------------------------------------------------------------------

Converts an array into a string suitable for use as a URL query string, using
the given key as the param name.

  ['Rails', 'coding'].to_query('hobbies') # => "hobbies%5B%5D=Rails&hobbies%5B%5D=coding"


= Array#to_s

(from ruby core)
------------------------------------------------------------------------------
  to_s()

------------------------------------------------------------------------------


(from gem activesupport-5.1.3)
------------------------------------------------------------------------------
  to_s(format = :default)

------------------------------------------------------------------------------


= Array#to_sentence

(from gem activesupport-5.1.3)
------------------------------------------------------------------------------
  to_sentence(options = {})

------------------------------------------------------------------------------

但是当我在 gedit 或其他 gnome 编辑器中打开它时，它就是这个样子。一些特定的词看起来很荒谬。任何建议或帮助将不胜感激。

= AArrrraayy##ttoo__ffoorrmmaatttteedd__ss

(from gem activesupport-5.1.3)
------------------------------------------------------------------------------
  to_formatted_s(format = :default)

------------------------------------------------------------------------------

Extends Array#to_s to convert a collection of elements into a comma separated
id list if :db argument is given as the format.

  Blog.all.to_formatted_s(:db)  # => "1,2,3"
  Blog.none.to_formatted_s(:db) # => "null"
  [1,2].to_formatted_s          # => "[1, 2]"


= AArrrraayy##ttoo__ppaarraamm

(from gem activesupport-5.1.3)

used by url_for in Action Pack.

the given key as the param name.

  ['Rails', 'coding'].to_query('hobbies') # => "hobbies%5B%5D=Rails&hobbies%5B%5D=coding"


= AArrrraayy##ttoo__ss

(from ruby core)
------------------------------------------------------------------------------
  to_s()

------------------------------------------------------------------------------


(from gem activesupport-5.1.3)
------------------------------------------------------------------------------
  to_s(format = :default)

------------------------------------------------------------------------------


= AArrrraayy##ttoo__sseenntteennccee

(from gem activesupport-5.1.3)
------------------------------------------------------------------------------
  to_sentence(options = {})

------------------------------------------------------------------------------

我尝试在每个系统中打开它。但是除了像 cat 或 less 这样的终端编辑器之外，文本仍然到处都是乱七八糟的。 跟文字编码有关系吗？

Answer 1

ri 输出格式为 ASCII text, with overstriking 的文档。您可以通过运行文件上的 file 命令来检查。

文档的某些部分是粗体，由一些字符、退格键 (^H) 和第一个字符表示。似乎 gedit 和其他 gnome 编辑器忽略了这些退格字符，使实际字符重复。

您可以像这样只输出 ASCII： ri Array | col -bx > array.txt
