How to jump to golang code in vim

When using the vim editor for golang development, it is often necessary to jump to the code to browse and modify the code. This article will introduce several methods for jumping golang code in vim to help improve development efficiency.

1. Using ctags

ctags is a cross-platform code indexing tool. Use it to generate a code tag file. This file contains variables, functions, and structures in the code. The position information of elements such as the body allows us to jump directly to the corresponding position in vim.

First you need to install ctags. The specific command is as follows:

sudo apt-get install ctags

After that, enter the golang project root directory in the command line and execute the following command to generate the tags file:

ctags -R

This command It will recursively traverse all golang code files in the current folder and its subfolders and generate a file named tags.

In vim, use Ctrl ] to jump to the variable definition, function definition, structure definition, etc. where the cursor is located, and use Ctrl o to jump back to the previous position.

2. Using vim-go plug-in

vim-go is a vim plug-in specially designed for golang developers. It can provide us with a series of tools and functions, among which This includes code jumps.

First you need to install the vim-go plug-in, which can be installed through vim's plug-in manager. Execute the following command in vim to install:

:PlugInstall fatih/vim-go

After the installation is completed, you can use vim-go to provide Use the command to jump to the code:

• Use the gd command to jump to the definition or declaration of the variable, constant, structure or interface at the cursor position.
• Use the gD command to jump to the definition or declaration of the function or method at the cursor position.
• Use the gi command to jump to the implementation of the interface at the cursor position.
• Use the gr command to jump to the reference of the function or method at the cursor position.

In addition, vim-go also provides some other code navigation functions, such as list display of functions, methods, variables, etc. of the current file, and display of calls to the function or method where the current cursor is located. chain.

3. Use fzf plug-in

After entering the search term, press the Enter key to jump to the corresponding location.

Summary

In the development of golang, vim is a very powerful editor. In order to improve development efficiency, we need to be proficient in code jumping skills. This article introduces three commonly used jump methods, namely using ctags, vim-go plug-in and fzf plug-in. Each method has its advantages and disadvantages, and developers need to choose the appropriate method to use based on their own needs and habits.
