How to set up Golang's development environment in Sublime Text

Sublime Text is a powerful text editor that can be used to write programs in various languages. Among them, Golang is one of the very popular programming languages. In this article, we will introduce how to set up a Golang development environment in Sublime Text.

First, we need to install Sublime Text and Golang. Sublime Text can be downloaded for free from the official website (https://www.sublimetext.com/). For the installation of Golang, please refer to the official documentation (https://golang.google.cn/doc/install).

After the installation is complete, we need to install some Sublime Text plug-ins to facilitate Golang development. We can install these plug-ins through Package Control. Package Control is a plug-in manager for Sublime Text that allows us to easily find and install other plug-ins.

To install Package Control, we can open Sublime Text and press Ctrl ` or View > Show Console menu option. Next, paste the following code in the console and execute it:

import urllib.request,os,hashlib; h = 'f2a813ca601ba1f402ebb6da988f199c' + 'e330c659d4bb41d3bdf022e94cab3cd0'; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); by = urllib.request.urlopen( 'http://packagecontrol.io/' + pf.replace(' ', '%20')).read(); dh = hashlib.sha256(by).hexdigest(); print('Error validating download (got %s instead of %s), please try manual install' % (dh, h)) if dh != h else open(os.path.join( ipp, pf), 'wb' ).write(by)

After the execution is completed, we can press Ctrl Shift P, then enter "install", select the "Package Control: Install Package" option, and search for the following plug-ins Install:

1. GoSublime: This is a plug-in developed for Golang. It provides syntax highlighting, code completion and other functions.
2. SublimeLinter: This is a code inspection tool that can help us check for syntax errors and potential problems in the code.
3. Gopls: This is a language server for code editing, which can help us with code completion, code navigation and other operations. Gopls can be installed through the following command:

GO111MODULE=on go get golang.org/x/tools/gopls@latest

After the installation is complete, we need to make some settings to ensure that these plug-ins can work properly. We can open GoSublime's settings file by pressing Ctrl Shift P, then entering "Preferences: GoSublime Settings", and then add the following content:

{
    "env": {
        "GOPATH": "/path/to/your/gopath",
        "PATH": "${PATH}:${GOPATH}/bin"
    }
}

Among them, /path/to/your/gopath needs to be replaced by your Own GOPATH path. This setting lets GoSublime know the location of GOPATH and add GOPATH/bin to the system path.

Next, we need to perform some configuration on SublimeLinter. We can press Ctrl Shift P, then enter "Preferences: Linter Settings" to open SublimeLinter's settings file, and then add the following content:

{
    "linters": {
        "golint": {
            "cmd": ["golint"],
            "args": [],
            "excludes": []
        }
    },
    "language": "go"
}

This configuration lets SublimeLinter know that we want to use golint to check the code. mistake. If golint is not installed, we can install it with the following command:

go get -u golang.org/x/lint/golint

Finally, we need to make Gopls available in Sublime Text. We can press Ctrl Shift P, then enter "Preferences: Key Bindings" to open Sublime Text's shortcut key configuration file, and then add the following content:

[
    {
        "keys": ["ctrl+alt+g"], "command": "gs_expr","args": {"mode": "gow"}
    }
]

This configuration allows us to use Ctrl Alt G in code to call Gopls functions.

At this point, Sublime Text’s Golang development environment is set up. We can use Sublime Text to write Golang programs and use these plug-ins to improve coding efficiency and code quality.
