Rename constants that use reserved names

Rename a constant if it uses a name of a built-in constant.

The inspection will be triggered if you try to assign a value to a constant with one of the following names: iota, true, or false. GoLand will suggest you to rename such usages.

How to use:

Place the cursor on a highlighted constant name, press ⌘⌥⏎ (macOS) / Ctrl+Alt+Enter (Windows/Linux), and select Rename constant. Type a new name and press ⏎ (macOS) / Enter (Windows/Linux).

Group multiple `use` directives in `go.work`

Merge multiple `use` directives in `go.work` into one directive.

If you have multiple use directives in your go.work file, you can merge them in a single one with a quick-fix.

How to use:

Place the cursor on a use directive, press ⌥⏎ (macOS) / Alt+Enter (Windows/Linux), and select Merge multiple use directives into one.

Fuzz testing

Automate your tests by continuously submitting various input.

Fuzz testing allows you to check your code against the various generated data. If fuzz testing fails, you can always see the reason in the testdata directory.

How to use:

In the \_test file, click the Run Test icon in the gutter and navigate to Run | go test -fuzz FuzzMyTest.

Run Anything

Launch run/debug configurations, applications, scripts, commands, tasks, and open recent projects.

Run Anything is a quick way to launch run/debug configurations, applications, scripts, commands, tasks, and open recent projects.

How to use:

To open the Run Anything dialog, use ⌃⌃ (macOS) / Ctrl+Ctrl (Windows/Linux). You can type ? to see the options available to you and then run HTTP requests, yarn, npm, and grunt tasks.

Quick Documentation

View documentation for any symbol without interrupting your workflow.

You can get quick information for any symbol right from the editor by means of the Quick Documentation feature. It shows you code documentation in a popup as you hover the mouse over code elements or use a corresponding shortcut.

How to use:

To see documentation about an element in your code, hover the mouse over the element, or click it and press F1 (macOS) / Ctrl+Q (Windows/Linux).

Delete a type parameter with an empty parameter list

Type parameters with empty parameter lists are reported as errors, but you have a quick-fix to put it right.

Type parameters with empty parameter lists are highlighted as errors. So, if you type func printInt[](i int), GoLand will highlight [] because the IDE expects type parameters here. In this case, you can either implement type parameters or delete square brackets. To delete square brackets, try the Delete type parameters quick-fix.

How to use: Place the cursor on the empty parameter list ([]), press ⌥⏎ (macOS) / Alt+Enter (Windows/Linux), and select Delete type parameters.

Convert empty interfaces to `any`

Check and replace empty interfaces that are used as types or type constraints.

GoLand has an inspection that reports usages of empty interfaces used as a type or a type constraint. To fix such usages, try the Replace with 'any' intention action.

How to use: Place the cursor on an empty interface, press ⌥⏎ (macOS) / Alt+Enter (Windows/Linux), and select Replace with 'any'.

Changing the font size in the editor

Use a keyboard shortcut to change the font size in the editor.

To increase the font size, press ⌃⇧. (macOS) / Alt+Shift+Period (Windows/Linux). To decrease it, press ⌃⇧, (macOS) / Alt+Shift+Comma (Windows/Linux).
