Go power tools that don't need anything installed: fold if err != nil blocks, add or remove struct tags in any case style, generate constructors, and jump between a file and its test.
Maintained. No sign-in. No telemetry. Works in VS Code, Cursor, Windsurf, VSCodium and other editors that use Open VSX.
Features
- Fold
if err != nil. Short error checks fold away when you open a Go file, so the happy path reads top to bottom, the way GoLand shows it. Fold Error Checks and Unfold Error Checks toggle them, and each one folds on its own from the gutter. Blocks with an else, or longer than 5 lines, stay open. Functions, structs, import groups and comments still fold from the gutter as usual.
- Struct tags. Put the cursor in a struct and open the light bulb (Ctrl+.) to add
json, yaml or db tags to every exported field, or remove a tag key. Existing tags and ,omitempty are kept. Names follow your style (json camelCase and snake_case elsewhere by default, configurable per key), and fields and tags are lined up like gofmt does. Add Struct Tags… offers more keys: xml, toml, bson, mapstructure, validate.
- Generate a constructor.
NewUser(id int64, firstName string, …) *User with every field, written below the struct.
- Go to Test / Implementation. Jump between
store.go and store_test.go. The test file is created with the right package and testing import if it doesn't exist yet. Optionally bind it to Ctrl+Shift+T.
- Nothing to install. Works on the source text, so it doesn't need Go, gopls or gomodifytags, and it runs alongside the official Go extension.
- Works in the browser on vscode.dev and github.dev.
