| Vet examines Go source code and reports suspicious constructs, such as Printf | |
| calls whose arguments do not align with the format string. Vet uses heuristics | |
| that do not guarantee all reports are genuine problems, but it can find errors | |
| not caught by the compilers. | |
| Vet is normally invoked through the go command. | |
| This command vets the package in the current directory: | |
| go vet | |
| whereas this one vets the packages whose path is provided: | |
| go vet my/project/... | |
| Use "go help packages" to see other ways of specifying which packages to vet. | |
| Vet's exit code is non-zero for erroneous invocation of the tool or if a | |
| problem was reported, and 0 otherwise. Note that the tool does not | |
| check every possible problem and depends on unreliable heuristics, | |
| so it should be used as guidance only, not as a firm indicator of | |
| program correctness. | |
| To list the available checks, run "go tool vet help": | |
| appends check for missing values after append | |
| asmdecl report mismatches between assembly files and Go declarations | |
| assign check for useless assignments | |
| atomic check for common mistakes using the sync/atomic package | |
| bools check for common mistakes involving boolean operators | |
| buildtag check //go:build and // +build directives | |
| cgocall detect some violations of the cgo pointer passing rules | |
| composites check for unkeyed composite literals | |
| copylocks check for locks erroneously passed by value | |
| defers report common mistakes in defer statements | |
| directive check Go toolchain directives such as //go:debug | |
| errorsas report passing non-pointer or non-error values to errors.As | |
| framepointer report assembly that clobbers the frame pointer before saving it | |
| hostport check format of addresses passed to net.Dial | |
| httpresponse check for mistakes using HTTP responses | |
| ifaceassert detect impossible interface-to-interface type assertions | |
| loopclosure check references to loop variables from within nested functions | |
| lostcancel check cancel func returned by context.WithCancel is called | |
| nilfunc check for useless comparisons between functions and nil | |
| printf check consistency of Printf format strings and arguments | |
| shift check for shifts that equal or exceed the width of the integer | |
| sigchanyzer check for unbuffered channel of os.Signal | |
| slog check for invalid structured logging calls | |
| stdmethods check signature of methods of well-known interfaces | |
| stdversion report uses of too-new standard library symbols | |
| stringintconv check for string(int) conversions | |
| structtag check that struct field tags conform to reflect.StructTag.Get | |
| testinggoroutine report calls to (*testing.T).Fatal from goroutines started by a test | |
| tests check for common mistaken usages of tests and examples | |
| timeformat check for calls of (time.Time).Format or time.Parse with 2006-02-01 | |
| unmarshal report passing non-pointer or non-interface values to unmarshal | |
| unreachable check for unreachable code | |
| unsafeptr check for invalid conversions of uintptr to unsafe.Pointer | |
| unusedresult check for unused results of calls to some functions | |
| waitgroup check for misuses of sync.WaitGroup | |
| For details and flags of a particular check, such as printf, run "go tool vet help printf". | |
| By default, all checks are performed. | |
| If any flags are explicitly set to true, only those tests are run. | |
| Conversely, if any flag is explicitly set to false, only those tests are disabled. | |
| Thus -printf=true runs the printf check, | |
| and -printf=false runs all checks except the printf check. | |
| For information on writing a new check, see golang.org/x/tools/go/analysis. | |
| Core flags: | |
| -c=N | |
| display offending line plus N lines of surrounding context | |
| -json | |
| emit analysis diagnostics (and errors) in JSON format | |
