Features
This extension provides many features, including IntelliSense,code navigation, and code editing support. It also shows diagnostics asyou work and provides enhanced support for testing and debugging yourprograms. See the full feature breakdown for more details and to learn how totune its behavior.
(Code completion and Signature Help)
In addition to integrated editing features, the extension provides severalcommands for working with Go files. You can access any of these by opening theCommand Palette (Ctrl+Shift+P on Linux/Windows and Cmd+Shift+P on Mac), andthen typing in the command name. See thefull list of commands provided by thisextension.
(Toggle Test File)
⚠️ Note: the default syntax highlighting for Go files is provided by aTextMate rule embedded in VSCode, not by this extension.
Tools
The extension uses a few command-line tools developed by the Go community. Inparticular, go, gopls, and dlvmust be installed for this extensionto work correctly. See the tools documentation for a completelist of tools the extension depends on.
In order to locate these command-line tools, the extension searchesGOPATH/bin and directories specified in the PATH environment variable (orPath on Windows) with which the VS Code process has started. If the tools arenot found, the extension will prompt you to install the missing tools and showthe '⚠️ Analysis Tools Missing' warning in the bottom right corner. Pleaseinstall them by responding to the warning notification, or by manually runningthe Go: Install/Update Tools command.
Setting up your workspace
Go modules are how Go manages dependencies inrecent versions of Go. Modules replace the GOPATH-based approach to specifyingwhich source files are used in a given build, and they are the default buildmode in go1.16+. While this extension continues to support both Go modules andGOPATH modes, we highly recommend Go development in module mode. If you areworking on existing projects, please consider migrating to modules.
Unlike the traditional GOPATH mode, module mode does not require the workspaceto be located under GOPATH nor to use a specific structure. A module isdefined by a directory tree of Go source files with a go.mod file in thetree's root directory.
Your project may involve one or more modules. If you are working with multiplemodules or uncommon project layouts, you will need to configure your workspaceby using Workspace Folders. Please see this documentation about supportedworkspace layouts.
Customization
Visual Studio 2017
The extension needs no configuration and should work out of the box. However,you may wish to adjust settings to customize its behavior. Please see thesettings documentation for a comprehensive list of settings.See advanced topics for further customizations and uniqueuse cases.
