What is a .go file?
Go (.go) is a plain-text source file for the Go programming language — a statically typed, compiled language from Google designed for simplicity and concurrency. It features goroutines and channels, a fast compiler, garbage collection, structs with methods, and interfaces, with a strict standard formatting.
How to use this file
Use an example .go file to test syntax highlighters, the Go compiler and vet, gofmt, linters, and parser or language-detection tooling.
How to use this file for testing
“Go Lint Invalid — Errcheck Invalid” is a deterministic Novus Examples fixture for Code parsing, Syntax highlighting, Editor testing. Short, known-correct source files in many languages with classes, functions, generics, enums, and error handling — for testing parsers, linters, formatters, language detection, and diff viewers.
Documented properties for this file: lint-invalid · go. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
This is a short, known-correct source file. Run it through your syntax highlighter, linter, formatter, tree-sitter grammar, or parser, and open it in the in-browser editor to tweak and re-download. Each snippet exercises comments, string escapes, literals, and language keywords.
