checker

Documentation

Overview

Package checker defines the implementation of the checker commands. The same code drives the multi-analysis driver, the single-analysis driver that is conventionally provided for convenience along with each analysis package, and the test driver.

Functions

func RegisterFlags

func RegisterFlags()

RegisterFlags registers command-line flags used by the analysis driver.

func Run

func Run(args []string, analyzers []*analysis.Analyzer) (exitcode int)

Run loads the packages specified by args using go/packages, then applies the specified analyzers to them. Analysis flags must already have been set. It provides most of the logic for the main functions of both the singlechecker and the multi-analysis commands. It returns the appropriate exit code.

Types

type TestAnalyzerResult

type TestAnalyzerResult struct {
	Pass        *analysis.Pass
	Diagnostics []analysis.Diagnostic
	Facts       map[types.Object][]analysis.Fact
	Result      interface{}
	Err         error
}

func TestAnalyzer

func TestAnalyzer(a *analysis.Analyzer, pkgs []*packages.Package) []*TestAnalyzerResult

TestAnalyzer applies an analysis to a set of packages (and their dependencies if necessary) and returns the results.

Facts about pkg are returned in a map keyed by object; package facts have a nil key.

This entry point is used only by analysistest.
