Introducing Vinego to Upsun

Vinego is a new set of safety-focused Go analyzers developed by Upsun, designed to enhance code safety by rejecting certain idiomatic patterns in favor of more explicit and potentially safer alternatives. These linters, such as varinit, allfields, capturederr, explicitcast, and loopvariableref, aim to address issues like zero-value initialization, error handling, type mixups, and loop variable references. Varinit ensures all variables are explicitly initialized, avoiding unexpected zero values. Allfields requires all struct fields to be explicitly set, preventing overlooked zero values in partial struct literals. Capturederr flags improper error handling in nested functions, while explicitcast forces explicit type casting to prevent type safety issues. Although some linting solutions may flag legitimate code, they aim to fill significant safety gaps in Go development. Vinego is available on GitHub and can be integrated with golangci-lint for a comprehensive Go-building solution.
