I redirected ri’s ruby Array doc into a file but it didn’t look good in gedit. But text looks just fine in cli. That’s how my file looks in terminal editors. Everything is fine here.
= 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 = {}) ------------------------------------------------------------------------------
But when I open it in gedit or other gnome editors, that’s how it looks like. Some specific words look in absurd format. Any suggestions or help will be appreciated.

Answer
ri
outputs documentation formatted as ASCII text, with overstriking
. You can check this by running the file
command on your file.
Some parts of the documentation are bolded, which is represented by some character, backspace (^H
) and the first character again. It seems that gedit and other gnome editors ignore these backspace characters, leaving the actual character repeated.
You can output just the ASCII like this:
ri Array | col -bx > array.txt
