A Linter lints Go source code.

func (*Linter) Lint

func (l *Linter) Lint(cfg *packages.Config, patterns []string) ([]Problem, error)

type Package

type Package struct {
	*packages.Package
	Imports []*Package
	// contains filtered or unexported fields
}

type Positioner

type Positioner interface {
	Pos() token.Pos
}

type Problem

type Problem struct {
	Pos      token.Position
	End      token.Position
	Message  string

Problem represents a problem in some source code.

func (*Problem) String

func (p *Problem) String() string

type Runner

type Runner struct {
	// contains filtered or unexported fields

func NewRunner

func NewRunner(stats *Stats) (*Runner, error)

func (*Runner) Run

func (r *Runner) Run(cfg *packages.Config, patterns []string, analyzers []*analysis.Analyzer, hasCumulative bool) ([]*Package, error)

Run loads packages corresponding to patterns and analyses them with analyzers. It returns the loaded packages, which contain reported diagnostics as well as extracted ignore directives.

Note that diagnostics have not been filtered at this point yet, to accomodate cumulative analyzes that require additional steps to produce diagnostics.
