Golang For Mac



GoLand is a cross-platform IDE built specially for Go developers

Strong Code Insight

On Mac you may need to enable/configure SU access (it is not available by default), but if you have managed to install Go you possibly already have root access. 2) Once you have all cross compilers built, you can happily cross compile your application by using the following settings for example.

GoLand makes it very easy to read, write, and change Go code

  • Go (golang programming language) Install Golang with Homebrew: $ brew update $ brew install golang When installed, try to run go version to see the installed version of Go. Setup the workspace: Add Environment variables: Go has a different approach of managing code, you'll need to create a single Workspace for all your Go projects.
  • Refactored and improved a medium-sized Golang legacy project using VSCode as IDE. Had trouble configuring and integrating a debugger, but works great after it is done. Code navigation for Go (with plugins) is sometimes not powerful enough: no way to fuzzy-search-and-jump to a.
  • Using the Go extension for Visual Studio Code, you get language features like IntelliSense, code navigation, symbol search, bracket matching, snippets, and many more that will help you in Golang.

On-the-fly error detection and suggestions for fixes, quick and safe refactorings with one-step undo, intelligent code completion, dead code detection, and documentation hints help all Go developers, from newbies to experienced professionals, to create fast, efficient, and reliable code.

Navigation & Search

Jump between types, files & other symbols

Exploring and understanding team, legacy, or foreign projects takes a lot of time and effort. GoLand code navigation helps you get around with instant switching to shadowed methods, implementations, usages, declarations, or interfaces implemented by types. Jump between types, files or any other symbols, or find their usages and examine them with convenient grouping by usage type.

Run & Debug

Powerful built-in tools help to run and debug your applications

Powerful built-in tools help to run and debug your applications. You can write and debug tests without any additional plugins or configuration effort, and test your applications right in the IDE. A built-in Code Coverage tool will make sure that your tests don’t miss anything important.

Integration with VCSs

Out-of-the-box support for Git, GitHub, and Mercurial

GoLand provides out-of-the-box support for Git, GitHub, and Mercurial. Perforce, ClearCase, and the others are supported by user-installable plugins.

More than just a Go IDE

GoLand wouldn’t be a true IDE without a rich set of tools

GoLand wouldn’t be a true IDE without a rich set of tools which, in addition to core Go development, support JavaScript, TypeScript, NodeJS, SQL, Databases, Docker, Kubernetes, and Terraform. All together, these capabilities make it perfectly equipped for working on any task, be it a modern web application or DevOps tools.

Shortly after GoLand was introduced, it replaced all other Golang IDEs at Grab. I had never seen engineers adopt software so quickly before. Kudos to JetBrains for delivering this great product.

Using the Go extension for Visual Studio Code, you get language features like IntelliSense, code navigation, symbol search, bracket matching, snippets, and many more that will help you in Golang development.

Golang

You can install the Go extension from the VS Code Marketplace.

IntelliSense

Auto completions

As you type in a Go file, you can see IntelliSense providing you with suggested completions. This even works for members in current, imported, and not yet imported packages. Just type any package name followed by ., and you will get suggestions for the corresponding package members.

By setting go.autocompleteUnimportedPackages to true in your settings, you can also get suggestion for packages that you could import. Select one of these suggestions and an import to the selected package will be added to your file.

Tip: Use ⌃Space (Windows, Linux Ctrl+Space) to trigger the suggestions manually.

Hover Information

Golang For Mac

Hovering on any variable, function, or struct will give you information on that item such as documentation, signature, etc.

By default, the extension uses godef and godoc to get this information. You can choose to use gogetdoc instead by changing the setting go.docsTool in your User or Workspace Settings.

Signature help

When you open the ( while calling a function, a pop-up provides signature help for the function. As you keep typing the parameters, the hint (underline) moves to the next parameter.

Tip: Use ⇧⌘Space (Windows, Linux Ctrl+Shift+Space) to manually trigger the signature help when the cursor is inside the () in the function call.

The extension's signature help also uses godef and godoc. You can choose to use gogetdoc instead by changing the setting go.docsTool in your User or Workspace Settings.

Code navigation

Code navigation features are available in the context menu in the editor.

  • Go To DefinitionF12 - Go to the source code of the type definition.
  • Peek Definition⌥F12 (Windows Alt+F12, Linux Ctrl+Shift+F10) - Bring up a Peek window with the type definition.
  • Go to References⇧F12 (Windows, Linux Shift+F12) - Show all references for the type.

You can navigate via symbol search using the Go to Symbol commands from the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)).

  • Go to Symbol in File - ⇧⌘O (Windows, Linux Ctrl+Shift+O)
  • Go to Symbol in Workspace - ⌘T (Windows, Linux Ctrl+T)

You can also navigate back and forth between a Go file and its test implementation using the Go: Toggle Test File command.

Build, lint, and vet

On save, the Go extension can run go build, go vet, and your choice of linting tool (golint or gometalinter) on the package of the current file. You can control these features via the settings below:

  • go.buildOnSave
  • go.buildFlags
  • go.vetOnSave
  • go.vetFlags
  • go.lintOnSave
  • go.lintFlags
  • go.lintTool
  • go.testOnSave

The errors and warnings from running any/all of the above will be shown red/green squiggly lines in the editor. These diagnostics also show up in the Problems panel (View > Problems).

Formatting

You can format your Go file using ⇧⌥F (Windows Shift+Alt+F, Linux Ctrl+Shift+I) or by running the Format Document command from the Command Palette or the context menu in the editor.

By default, formatting is run when you save your Go file. You can disable this behavior by setting editor.formatOnSave to false for the [Go] language. You can change this using your json setting files

You can choose among three formatting tools: gofmt, goreturns, and goimports by changing the setting go.formatTool.

Test

There are many test-related commands that you can explore by typing 'Go: test' in the Command Palette.

The first three above can be used to generate test skeletons for the functions in the current package, file or at cursor using gotests. The last few can be used to run tests in the current package, file or at cursor using go test. There is also a command for getting test coverage.

Import packages

Golang Macros

Run the command Go: Add Import to get a list of packages that can be imported to your Go file. Choose one and it will get added in the import block of your Go file.

Golang Machinery

Rename symbols

You can rename symbols using F2 or by running the Rename Symbol command in the context menu in the editor.

Debugging

The Go extension lets you debug Go code as well. You will need to install the Delve debugger manually as a prerequisite. Read Debug Go programs in VS Code for setup steps, information on remote debugging and a troubleshooting guide.

Next steps

This has been a brief overview showing the Go extension features within VS Code. For more information, see the details provided in the Go extension README.
