The new Dump Goroutines icon in the debugger lets you easily find goroutines that contain a specified string in the stack during the debug session. Simply click the icon to open a dump in a separate window.
To help you keep focus on information that matters there is the option to hide an individual goroutine or goroutines with the same stack. Right-click on a goroutine and select the desired action or just press delete to move it to a special Hidden section in the dump window where it won’t distract you.
GoLand 2020.3 brings the ability to stop a process with Go Remote configuration if no reattach is required.
In your configuration settings you can specify the default behavior of the debugger on disconnect, you can choose Stop remote Delve processes, Leave it running, or have GoLand ask you how to proceed each time.
You can run and navigate to individual table tests from the Run tool window.
There are some limitations:
The IDE now recognizes the test function that starts a test suite, and provides a way to
start an individual
suite.T().Run, as long as the subtest name is a string
constant. In addition, it is possible to rerun a subtest from the Run tool window to avoid
rerunning the entire top-level test.
In addition, GoLand can now run Testify suites with the same method name separately within a single test case.
Last but not least, when you complete a function or method that accepts
testing.T as the
first argument, GoLand passes that argument automatically if possible. This works for
functions and methods of
The Incorrect usage of Println/Printf like functions code inspection will warn you about
potential problems in
On top of that, we’ve added placeholder highlighting and folding, as well as the Add format string argument intention.
The context.CancelFunc not called code inspection reports potentially unsafe uses of context
cancellation. This is especially useful when the ‘cancel’ function returned by
context.WithCancel (and similar functions) isn’t called on all execution paths.

We’ve added support for the time package so you can work with time and duration more easily.
GoLand will suggest elements of predefined layout via code completion(Ctrl+Space) as
DD placeholders from ISO-8601.
Press Ctrl+P on a token, and the IDE will show its meaning. There is also syntax highlighting for layout tokens. Code completion also suggests standard time layouts outside of the string literal.
The IDE is now smarter at prioritizing completion items for packages that you use frequently and
that are explicitly declared in the
go.mod file of your project.
We’ve also added an option to exclude packages completely from your project import path and completion suggestions. You can do this via Alt+Enter or in the new Exclude for import and completion window in Settings | Go | Imports.
GoLand makes it easier to spot variable shadowing:
We’ve followed updates from the design of generics by the Go team and added support for square brackets for the generics syntax instead of parentheses, as this was implemented in the previous proposal edition.
Please note that the Enable generics (experimental support for type parameters) setting in Settings | Go is turned off by default. You need to explicitly select that checkbox to start using the feature.
Read this blog post to learn more about type parameters.
When you type
func in the test file, GoLand by default suggests
test Live Templates in the completion options.
When you type
for inside the benchmark, the IDE suggests completing it with a for loop with
Suggestions now appear immediately in the dialog when you press Alt+Enter. In addition, a new version of the LanguageTool grammar checking engine features improved checks for English and adds support for 10 additional languages.
GoLand 2020.3 supports Code With Me (EAP) – a new service from JetBrains for collaborative development and pair programming. Code With Me enables you to share the project you currently have open in your IDE with others and work on it together in real time.
Check out these posts to learn more about it.
We’ve reworked the Welcome screen to give you immediate access to:
Select the Sync with OS option in Settings | Appearance & Behavior | Appearance | Theme to automatically switch your IDE theme to match your OS preferences.
Split the main editor screen horizontally or vertically by dragging a tab to the desired position and dropping it there. When you are dragging a tab, the editor will highlight where you can drop it.
We’ve improved the UX when working with files from the Project view. Now when you open a file from the Project view, the focus is automatically placed on the editor to allow you to start working with your code right away. Press the spacebar and the IDE will show you a preview of the file in the Project view.
If you want to have several files open in the editor simultaneously, you can now do so with one simple shortcut. Select the file in the Project view and press Shift+Enter to have the IDE split the Editor window and open the file in the right-hand part of it.
The VCS menu now adapts to version control system that you are currently using, making it easier to access key VCS features as they are no longer hidden in a submenu.
There is an awesome new Git staging area available! Please note that this functionality is only available for the Commit tool window.
Tick the Enable staging area checkbox in Settings | Version Control | Git to turn it on. Once you do, support for changelists will be disabled.
In the commit UI, you will find staged and unstaged files. When you’re ready to stage a file, simply click the + icon next to it. The file will appear under the Staged node. To add your changes to the staging area you can also use the gutter icon or Show Diff.
Work with branches has been improved:
We’ve added the ability to enable plugins for the current project or for all projects by selecting Enable for Current Project or Enable for All Projects. In Settings | Plugins, press the gear icon on the plugin you want to enable or disable and select the desired option.
macOS system shortcut keymap (Settings | Keymap) aims to provide you with an alternative macOS keymap that offers extended compatibility with system shortcuts and allows you to avoid using F-keys for essential actions.
We’ve improved the search mechanism of the Flame Graph in the Profiler and its visualization to let you find method metrics faster. You can click on the magnifying glass icon or type your search request inside the Flame Graph panel.
Also, we’ve added a search field, up/down arrows for fast navigation between search results, and the ability to search either in the whole Flame Graph or just in a specific subtree.
Courtesy of the WebStorm team, GoLand now has rich support for web development under the hood. One of the upcoming changes in this area is the ability to create a React component from an unresolved reference. Place the caret at an unresolved component, press Alt+Enter, and select the corresponding inspection.
GoLand provides full support for the pnpm package manager, along with npm and yarn. When you open a project with a pnpm-lock file and have pnpm installed on your machine, GoLand will automatically change the package manager for this project to pnpm. The IDE also has a dedicated pnpm option in the list of package managers under Settings | Languages and Frameworks | Node.js and NPM.
Thanks to our colleagues from the DataGrip team, GoLand has expanded its family of supported databases with a new member – Couchbase! Please note that the IDE supports the Couchbase Query service, not the Couchbase Analytics service.
GoLand knows about object grants and displays them in an object’s DDLs. This works for MySQL, PostgreSQL, Greenplum, Redshift, and SQL Server.
We’ve improved the separate editor for cell values:
We’ve added two new extractors to help make it easier for you to work with data:
INSERTstatement with multiple new rows to be inserted.
In addition, there is now a new option in CSV format configuration: never quote values.
