Tooltitude for Go is a productivity extension for the Go programming language. It helps you write better code faster. The extension is being actively developed so stay tuned for new features (Twitter is the best place to do so https://twitter.com/tooltitude).
Features
CodeLens providers
Gain insights into your codebase, and understand usage patterns for functions, methods, fields, and interfaces.
We have CodeLens providers which help you navigate code and see what's going on in the code base
Code Inspections
From unused initializations and writes to shadowed variables, unhandled errors, and deprecated symbols, our inspections help you enhance your code.
References View
Get more information than the built-in references popup. References view allows you to see not only the file where the reference is located, but its package, function. Note: it works only with Tooltitude CodeLens providers.
Debug Individual Table Driven Tests
Debug Individual test driven tests with our debugging code lens.
Postfix Completions
Write code faster by using familiar dot notation to generate boilerplate code: generate statements, call library functions, iterate collections and more.
Code Actions
Make common code changes with confidence: handle errors, manipulate variables, transform expressions and more.
Premium Features
We have a set of premium features which are available for a license fee:

Use code actions to navigate to methods, implementing interfaces/methods, implemented interfaces/methods. Don't break your flow by using a mouse or touchpad.
⭐ Inline Values In The Debugger
See variable and parameter values right in your editor
⭐ Workspace Wide Unused Symbols Report
Fine entities with no source code reference in the whole workspace
⭐ Inlay Reference Counters
Save vertical space with inlay reference counters
⭐ Run/Debug from a Keyboard
Run and Debug tests, and main methods from a keyboard. Don't break your flow by using a mouse or touchpad.

- Postfix Completions
- Completion for builtin types to invoke standard functions involving these types. As an example, you could write "abc".ToLower and transform it to strings.ToLower("abc)
- .if for "if expr { }"; .ifn for "if !expr { }"
- .ifnil for "if expr == nil { }"; .ifnnil for "if expr != nil { }"
- .ifempty for "if len(expr) == 0 { }"; .ifnempty for "if len(expr) != 0 { }"
- .parens for "(expr)"
- .print, .println, .panic, .len, .cap, .close, .new, .delete, .append or .make to call the corresponding standard library functions
- .for, .switch, .return, and .defer to complete the corresponding statements
- .for_range for automatic creation of iteration variables based on expression type
- .&, .!, .*, .<- for &expr, !expr, *expr, <-expr
- .var and .const for "var/const id = expr"
- .=/:= for "id = expr" / "id := expr"
- Code Actions

- Show references
- ⭐ Show implementations/implementers for methods/interfaces
- ⭐ Show implemented interfaces/implementing types
- ⭐ Show type methods
- ⭐ Show package imports
- ⭐ Move declaration
