NAME

go - tool for managing Go source code

SYNOPSIS

go list [-e] [-f format] [-json] [ packages ]

DESCRIPTION

List lists the packages named by the import paths, one per line.

The default output shows the package import path:

      code.google.com/p/google-api-go-client/books/v1
      code.google.com/p/goauth2/oauth
      code.google.com/p/sqlite

OPTIONS

-f

The -f flag specifies an alternate format for the list, using the syntax of package template. The default output is equivalent to -f '{{.ImportPath}}'. The struct being passed to the template is:

      type Package struct {
          Dir        string // directory containing package sources
          ImportPath string // import path of package in dir
          Name       string // package name
          Doc        string // package documentation string
          Target     string // install path
          Goroot     bool   // is this package in the Go root?
          Standard   bool   // is this package part of the standard Go library?
          Stale      bool   // would 'go install' do anything for this package?
          Root       string // Go root or Go path dir containing this package
      
          // Source files
          GoFiles  []string  // .go source files (excluding CgoFiles, TestGoFiles, XTestGoFiles)
          CgoFiles []string  // .go sources files that import "C"
          CFiles   []string  // .c source files
          HFiles   []string  // .h source files
          SFiles   []string  // .s source files
          SysoFiles []string // .syso object files to add to archive
      
          // Cgo directives
          CgoCFLAGS    []string // cgo: flags for C compiler
          CgoLDFLAGS   []string // cgo: flags for linker
          CgoPkgConfig []string // cgo: pkg-config names
      
          // Dependency information
          Imports []string // import paths used by this package
          Deps    []string // all (recursively) imported dependencies
      
          // Error information
          Incomplete bool            // this package or a dependency has an error
          Error      *PackageError   // error loading package
          DepsErrors []*PackageError // errors loading dependencies
      
          TestGoFiles  []string // _test.go files in package
          TestImports  []string // imports from TestGoFiles
          XTestGoFiles []string // _test.go files outside package
          XTestImports []string // imports from XTestGoFiles
      }
    

-json

The -json flag causes the package data to be printed in JSON format instead of using the template format.

-e

The -e flag changes the handling of erroneous packages, those that cannot be found or are malformed. By default, the list command prints an error to standard error for each erroneous package and omits the packages from consideration during the usual printing. With the -e flag, the list command never prints errors to standard error and instead processes the erroneous packages with the usual printing. Erroneous packages will have a non-empty ImportPath and a non-nil Error field; other information may or may not be missing (zeroed).
