How to run ruby ​​files?

Question

Example. I have a test.rb file:

puts "test test test" 

How to run this file in ruby ​​console?

Answer 1

load 'test.rb'

Do you mean the Rails console? (Same thing, but the question is related to rails.)

Answer 2

 load("test.rb") 

should do the trick in irb .

Answer 3

On a Mac, you can run three different methods from the terminal. Method 1 In the irb (Interactive Ruby Shell) terminal to execute line by line, then close the command to exit irb.

Method 2 Since ruby ​​is an interpreted language, we can run one command on the terminal

• Save the text editor code with the extension .rb.
• Change the directory in the terminal with the cd command (cd drag the folder to the terminal so that you can be redirected to the directory).
• ruby hello.rb

Method 3 ruby ​​-v know the ruby ​​version ruby ​​-e 'puts WVU' #line on a line in the terminal

Answer 4

Any ruby ​​file can only be launched with ruby <your_ruby_file.rb> if you are in the same directory as the ruby ​​file; If not, just specify the file path:

 ruby path/to/your_file.rb
