Programming Ruby 3.2 (5th Edition): B4.0 many places, require "name" or require name

@noelrappin

Many places have require “name”, other require name. If you want to have the same style everywhere, the following pages are concerned :

+++++ NOT page 117, last paragraph, When you require BigDecimal, which is OK because require is in the normal font

+++++ page 253, first line after the green Info :

Now the gem is ready to be used, which means that any Ruby program can require rspec and
                                                                -----> ^^^^^^^^^^^^^

+++++ page 256, last paragraph, first and second to last line :

Alternately, inside your code, before you use any gems, you can require bundler/setup, which
                                                         -----> ^^^^^^^^^^^^^^^^^^^^^
...
exec code that also has a require bundler/setup that’s fine, the management work will only be
                   -----> ^^^^^^^^^^^^^^^^^^^^^

+++++ page 257, fourth paragraph from bottom, two first lines :

Be default, when you engage Bundler via Bundler.require or require bundler/setup each gem will
                                                    -----> ^^^^^^^^^^^^^^^^^^^^^
be autoloaded under the name of the gem. In other words, gem rspec implies require rspec.
                                                                    -----> ^^^^^^^^^^^^^

+++++ page 261, second paragraph, two times with mistake (bundle instead of bundler) :

`require': cannot load such file -- bundle/setup (LoadError)
Did you mean?  bundler/setup
`require': cannot load such file -- bundle (LoadError)
Did you mean?  bundler

Shoul be : … rather than require “bundler/setup”, you just require
“bundler”

+++++ page 292, first paragraph, lines 2-3 :

There is the jj method, which you need to require json to have access to, and which creates
                                   -----> ^^^^^^^^^^^^
pretty-printed JSON. It also has y, which comes when you require yaml and produces the
                                                  -----> ^^^^^^^^^^^^

+++++ page 293, second paragraph, lines 1 + 3 :

Alternately, you can use require debug/open in the background process, which allows you to
                  -----> ^^^^^^^^^^^^^^^^^^
the first line; if you want the program to run normally, use require debug/open_nonstop. How
                                                      -----> ^^^^^^^^^^^^^^^^^^^^^^^^^^

+++++ page 296, in Pry, fourth paragraph, lines 2-3 :

that with the same code we used for the debugger earlier, just replacing require debug with
                                                                  -----> ^^^^^^^^^^^^^
require pry and the binding.break call with binding.pry, we get this:
^^^^^^^^^^^ <-----

+++++ page 497, paragraph 3, line 3, already mentioned in a previous post
+++++ page 507, in BigDecimal, fourth paragraph from bottom, first line, as mentioned in the previous post

+++++ page 509, second to last paragraph, line 3 :

The formatter module, which gets mixed in with require random/formatter, gives you a set of
                                        -----> ^^^^^^^^^^^^^^^^^^^^^^^^

+++++ page 510, second paragraph after code, first line :

With the line require random/formatter, you get a number of useful methods mixed in to Random.
       -----> ^^^^^^^^^^^^^^^^^^^^^^^^

+++++ page 567, in FileUtils, second paragraph, first line :

To use these methods, you need to require fileutils. All the methods here are defined as module
                           -----> ^^^^^^^^^^^^^^^^^

+++++ page 639, last paragraph, lines 1-2 :

When using JRuby, you can import any Java library in your Java class path. If you add require
java to your file
^^^^ <----- "java"
