$ go vet -vettool=$(which vet)

-V=full         describe executable               (to the build tool)
-flags          describe flags                    (to the build tool)
foo.cfg         description of compilation unit (from the build tool)

func Main

func Main(analyzers ...*analysis.Analyzer)

Main is the main function of a vet-like analysis tool that must be invoked by a build system to analyze a single package.

The protocol required by 'go vet -vettool=...' is that the tool must support:

-flags          describe flags in JSON
-V=full         describe executable for build caching
foo.cfg         perform separate modular analyze on the single
                unit described by a JSON config file foo.cfg.

func Run

func Run(configFile string, analyzers []*analysis.Analyzer)

Run reads the *.cfg file, runs the analysis, and calls os.Exit with an appropriate error code. It assumes flags have already been set.

type Config

type Config struct {
    ID                        string // e.g. "fmt [fmt.test]"
    Compiler                  string
    Dir                       string
    ImportPath                string
    GoFiles                   []string
    NonGoFiles                []string
    ImportMap                 map[string]string
    PackageFile               map[string]string
    Standard                  map[string]bool
    PackageVetx               map[string]string
    VetxOnly                  bool
    VetxOutput                string
    SucceedOnTypecheckFailure bool
}

A Config describes a compilation unit to be analyzed. It is provided to the tool in a JSON-encoded file whose name ends with ".cfg".
