It uses static analysis of source code or a binary's symbol table to narrow down reports to only those that could affect the application. By default, govulncheck makes requests to the Go vulnerability database at https://vuln.go.dev. Requests to the vulnerability database contain only module paths, not code or other properties of your program.

Enforce a stricter format than gofmt, while being backwards-compatible. That is, gofumpt is happy with a subset of the formats that gofmt is happy with. The tool is a fork of gofmt as of Go 1.19, and requires Go 1.18 or later. It can be used as a drop-in replacement to format your Go code, and running gofmt after gofumpt should produce no changes. gofumpt will never add rules which disagree with gofmt formatting. So we extend gofmt rather than compete with it.
