How to Prevent goimports from Removing Unused Imports When Using IDE Autosave?

How to Handle Unused Imports with goimports and IDE Autosave

When using goimports for automatic code reformatting and import ordering, it may not work seamlessly with IDE autosave, especially when adding new packages. This issue arises because goimports removes unused package imports when the file is saved, despite the package being installed and used in the IDE.

To resolve this issue, consider the following solutions:

• Invoke dep ensure -add package/name manually: This adds the package to the dependency list without the import line in the code. The IDE will automatically infer the import and add it as needed.
• Disable goimports and switch to gofmt: gofmt does not remove unused imports, providing a consistent experience regardless of IDE autosave.
• Avoid autoformatting code on save: While undesirable, it prevents goimports from modifying the imports.
• Configure IDE to manage imports: Some IDEs provide settings to disable automatic import removal or delay formatting until a specific key combination is pressed.

Note on godeps and DEP

The tag "godeps" is not relevant to this issue. However, the solution provided assumes the use of dep ensure for dependency management, which may become obsolete as DEP has been deprecated in favor of Go modules.
