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":

	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 that +build tags are well-formed and correctly located
	cgocall      detect some violations of the cgo pointer passing rules
	composites   check for unkeyed composite literals
	copylocks    check for locks erroneously passed by value
	httpresponse check for mistakes using HTTP responses
	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
	slog         check for incorrect arguments to log/slog functions
	stdmethods   check signature of methods of well-known interfaces
	structtag    check that struct field tags conform to reflect.StructTag.Get
	tests        check for common mistaken usages of tests and examples
	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

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
