Coding assistance in Go

Code completion

As you type, JetBrains Fleet suggests completion options. The suggestions are based on a number of factors, such as the available code intelligence services, project model, surrounding code, and the visibility of symbols.

Completion suggestions will appear automatically as you type, but you can also invoke them explicitly by pressing ⌃ Space.

When you use code completion over existing code items, you can either insert the selected completion suggestion before the existing item by pressing Enter or replace the existing identifier with the selected suggestion by pressing Tab.

Postfix code completion

With post-fix templates, you can transform an already-typed expression to a different one based on a postfix after the dot, the type of the expression, and its context. JetBrains Fleet includes a set of predefined postfix completion templates that you can use for other programming languages as well.

Code actions

JetBrains Fleet constantly analyzes your code and suggests actions that you might want to perform in the current context. The suggested actions range from correcting errors to refactoring the code at the caret.

To see, which actions are available at the caret, press ⌥ ⏎. After you have selected the required action, you can apply it right away or preview the result with ⌘ P.

Apply a primary quick-fix

1. Open the Problems popup, which is in the upper-right corner of the window.

2. Click the issue that you want to fix from the list of problems.

3. While the issue is selected, press ⌥ ⇧ ⏎. Alternatively, you can click the link with the suggested quick-fix.

Parameter info

If you are using a method that has numerous overloads, or just want to look up the required parameters, use ⌘ I.

Live templates

Use live templates to insert common constructs into your code, such as loops, conditions, declarations, or print statements.
