golang vim jump

Golang is a very popular programming language, which is characterized by simplicity, efficiency, security and good performance. Vim is a text editor with a long history and wide application, and it is also very popular among programmers. During the development process of Golang, how to better interact with Vim and Golang has become one of the hot topics among many developers.

Among them, the jump functions of Vim and Golang are particularly valued. Normally, when we edit Golang code, we often need to check the specific implementation location of a function, variable, structure, etc. definition, and then modify and debug it. At this time, you need to use Vim to jump forward or backward to the code position to improve our programming efficiency and work experience.

In this article, we will provide some practical tips on how to perform Golang jump in Vim, and share some related plug-ins or tools with you. At the same time, in order to ensure the readability and practicality of the article, we will explain it from the following aspects:

1. Use Vim’s basic jump function

2. Use Golang’s standards Jump to godoc in the library

3. Use plug-ins or tools to jump

1. Use Vim’s basic jump function

Vim is a veteran text editor It provides many practical text editing functions, including jumping to a specific location. In Vim, we can use the following commands to achieve basic jumps:

1. Command "G": jump the cursor to the end of the file;

2. Command "gg" : Jump the cursor to the beginning of the file;

3. Command ":": Jump the cursor to the specified line number; where linenumber is the specific line number;

4. Command "/": Find text matching the specified pattern in the file, and jump the cursor to the first matching position; where pattern is a specific text pattern.

Although these commands can meet the code jumping needs in some simple scenarios, they are still insufficient for how to jump to functions, structures, variables, etc. in Golang code.

2. Use godoc in Golang’s standard library to jump

In the standard library of Go language, a command named godoc is provided, which can be displayed in the command line terminal Documentation of the current project, including the specific implementation locations of project structure, functions, variables, etc. definitions.

To use godoc to jump to a specific function or structure, just type "godoc package/function" or "godoc package/type" in the terminal, where package is the specific package name and function is specific Function name, type is the specific structure name. For example, if we want to view the specific implementation location of the "Println" function in the "fmt" package, we can type "godoc fmt/Println" in the terminal, and the definition of the function and its specific implementation location will be displayed in the terminal. If you want to open the terminal quickly, you can use the ":! command" in Vim to open the terminal window.

Of course, if we want to jump directly to the specific implementation location of the specified function in godoc in Vim, there is a way. You can use the command ":grep pattern godoc -src package |grep pattern |head -1" in Vim, where pattern is the specific function name or structure name, and package is the specified package name. The function of this command is to search for results matching pattern in godoc and return the path of the matched first line of code to Vim. In this way, we can quickly locate the specific location of a specific function and perform debugging or editing operations.

3. Use plug-ins or tools to jump

In order to jump to Golang code more conveniently, you can also choose to install some related plug-ins or tools for Vim.

1.Godef plug-in

Godef plug-in is a very practical Golang tool. It parses the symbols in the code, their definitions, and reference relationships, and generates a data structure similar to tags. Implemented quick jump function. To install Godef plug-ins, you can use plug-in managers such as Vim-Plug or Vundle. After the installation is complete, use the command ":Godef " in Vim to quickly jump to the specific implementation location of the function. In addition, Godef also supports viewing function call paths, variable definitions, and other convenient functions.

2.GoToDef plug-in

GoToDef is another very practical Vim plug-in. It analyzes the code files and standard libraries to correlate the definitions and reference relationships of custom functions and variables in the code. together, thus realizing the quick jump function. To install the GoToDef plug-in, you can use plug-in managers such as Pathogen or NeoBundle. After the installation is complete, use the command ":GoToDef" in Vim to realize the quick jump function.

3.vimgo plug-in

vimgo is a high-end Golang development plug-in. It provides many practical functions, including jump, positioning, search, etc., which can quickly improve the work of developers. efficiency. It also facilitates programmers to quickly develop and debug Golang code in Vim through minimalist design and ease of use.

Summarize

Through the introduction of this article, I believe that everyone can better master the basic methods and techniques of Golang jump in Vim. Whether we use basic Vim jump commands, call godoc to query the specific implementation of functions and variables, or install some practical plug-ins or tools, we can develop and debug Golang code more quickly and efficiently. . Therefore, when developing and debugging Golang programs, we should make full use of practical functions such as jumps in Vim to improve our development efficiency and work experience.
