1. What is RDT?

RDT (Ruby development tools), a set of Eclipse plug-ins, enables eclipse to support Ruby development.
Eclipse is a powerful cross-platform integrated development environment that supports development in Java, JSP, PHP, and other places.

For the advantages of the two, refer to Google or the link at the end of the article.

2. Install configurations

First, install the RDT plug-in. You can download it from the following URL and then install it.

After restarting eclipse, select new project. At this time, we can see a ruby.

This indicates that RDT has been installed. Before using RDT, you must specify the Ruby interpreter, open the preferences window, find the installed interpreters in Ruby, and click Add on the right, then add the location of your Ruby interpreter:

After confirmation, the interface is as follows:

　

　

　

　

3. Development Program

Then we can write the program. You can create a test. RB file as follows:

ClassTest DefSayhello Puts"Hello World" End End T = test. New T. sayhello

　

Right-click the file and choose run> RUN Ruby application.

　

　

The execution result is as follows:

　

　

　

If you want to debug, you can set the endpoint, and then debug it in the same way as developing a Java program. For example

　

　

　

　

4. Code Completion

Because Ruby is a dynamic language, it is difficult to implement Code Completion (Automatic completion or prompting). RDT provides only some basic things that can be used in the current class, most of them are syntactic things, such as defining methods and for loops.

In the prompt box that opens the code, CTRL + space is required. The system is dizzy. By default, you have to switch the input method, but you have to change the shortcut key for switching the input method. (This may cause problems because I am used to switching to English with Ctrl + space)
