golang view method

The Go language is a concise, efficient, concurrency-safe and garbage-collected programming language that has proven to be a powerful tool for scalable service applications and web applications. Whether you are a newbie or an experienced programmer, you need to know how to view methods in Golang. Next, we'll cover how to view methods and which tool should be used in which situation.

Using a text editor and the command line

First, let’s see how to view methods using a text editor and the command line. In this case, you need a text editor such as Notepad, VS Code or Notepad. You also need to install Golang and set environment variables. The next steps are as follows:

1. Open the Go file you want to view.
2. Find the method you want to view.
3. Then, launch a terminal or open a command line using a command line tool and navigate to the directory containing the file.
4. Enter the following command: go doc <package_name> <function_name></function_name></package_name>, where <package_name></package_name> is the package name, <function_name></function_name> is the method name.
5. Then, press the Enter key. Documentation for the method will be displayed.

For example, if you want to view information for the fmt.Printf() method, you would enter the following:

go doc fmt Printf

Use godoc

Another way to view the methods is to use the godoc tool. godoc is Go's own documentation generator, which can generate documentation for Go code and packages. This tool can be viewed in a browser and does not require any third-party editor. Here are the steps to use godoc:

1. First, you need to install godoc (godoc is already pre-installed after Go is installed).
2. Then, open the Go file using your favorite text editor and find the method you want to view.
3. Then, use the command line tool to open a terminal and enter the following command to start the godoc server: godoc -http=:6060.
4. Then, enter "localhost:6060" in the web browser to open the godoc server page.
5. Enter the documentation page and find the package or method you want to view. You can find them using the search box or browsing the page.
6. Click the method name and it will automatically jump to the documentation page about the method.

GoLand integrated viewing

There is also an easier way, open the file you want to view in GoLand, and then use the keyboard shortcut Ctrl and left-click the method you want to view That’s it. This will open a new window with information about the method.

Conclusion

Whether you use a text editor and the command line, or Godoc and GoLand, you can find and view methods in Golang. Therefore, which tool to choose also depends on your personal preferences and specific circumstances. Using these tools, you can more easily understand how methods work, allowing you to better manage and write Golang programs.
