package imports

import "golang.org/x/tools/internal/imports"

Package imports implements a Go pretty-printer (like package "go/format") that also adds or removes import statements as necessary.

Index

Package Files

fix.go imports.go mod.go mod_cache.go sortimports.go zstdlib.go

Constants

const MaxRelevance = 7.0

MaxRelevance is the highest relevance, used for the standard library. Chosen arbitrarily to match pre-existing gopls code.

Variables

var RequiredGoEnvVars = []string{"GO111MODULE", "GOFLAGS", "GOINSECURE", "GOMOD", "GOMODCACHE", "GONOPROXY", "GONOSUMDB", "GOPATH", "GOPROXY", "GOROOT", "GOSUMDB"}

func ApplyFixes Uses

func ApplyFixes(fixes []*ImportFix, filename string, src []byte, opt *Options, extraMode parser.Mode) (formatted []byte, err error)

ApplyFixes applies all of the fixes to the file and formats it. extraMode is added in when parsing the file. src and opts must be specified, but no env is needed.

func GetAllCandidates Uses

func GetAllCandidates(ctx context.Context, wrapped func(ImportFix), searchPrefix, filename, filePkg string, env *ProcessEnv) error

GetAllCandidates calls wrapped for each package whose name starts with searchPrefix, and can be imported from filename with the package name filePkg.

func GetImportPaths Uses

func GetImportPaths(ctx context.Context, wrapped func(ImportFix), searchPrefix, filename, filePkg string, env *ProcessEnv) error

GetImportPaths calls wrapped for each package whose import path starts with searchPrefix, and can be imported from filename with the package name filePkg.

func GetPackageExports Uses

func GetPackageExports(ctx context.Context, wrapped func(PackageExport), searchPkg, filename, filePkg string, env *ProcessEnv) error

GetPackageExports returns all known packages with name pkg and their exports.

func ImportPathToAssumedName Uses

func ImportPathToAssumedName(importPath string) string

ImportPathToAssumedName returns the assumed package name of an import path. It does this using only string parsing of the import path. It picks the last element of the path that does not look like a major version, and then picks the valid identifier off the start of that element. It is used to determine if a local rename should be added to an import for clarity. This function could be moved to a standard package and exported if we want for use in other tools.

func PrimeCache Uses

func PrimeCache(ctx context.Context, env *ProcessEnv) error

func Process Uses

func Process(filename string, src []byte, opt *Options) (formatted []byte, err error)

Process implements golang.org/x/tools/imports.Process with explicit context in opt.Env.

func ScoreImportPaths Uses

func ScoreImportPaths(ctx context.Context, env *ProcessEnv, paths []string) (map[string]float64, error)

func VendorlessPath Uses

func VendorlessPath(ipath string) string

VendorlessPath returns the devendorized version of the import path ipath. For example, VendorlessPath("foo/bar/vendor/a/b") returns "a/b".

type ImportFix Uses

type ImportFix struct {
    // StmtInfo represents the import statement this fix will add, remove, or change.
    StmtInfo ImportInfo
    // IdentName is the identifier that this fix will add or remove.
    IdentName string
    // FixType is the type of fix this is (AddImport, DeleteImport, SetImportName).
    FixType   ImportFixType
    Relevance float64 // see pkg
}

func FixImports Uses

func FixImports(filename string, src []byte, opt *Options) (fixes []*ImportFix, err error)

FixImports returns a list of fixes to the imports that, when applied, will leave the imports in the same state as Process. src and opt must be specified.

Note that filename's directory influences which imports can be chosen, so it is important that filename be accurate.

type ImportFixType Uses

type ImportFixType int
const (
    AddImport ImportFixType = iota
    DeleteImport
    SetImportName
)

type ImportInfo Uses

type ImportInfo struct {
    ImportPath string // import path, e.g. "crypto/rand".
    Name       string // import name, e.g. "crand", or "" if none.
}

An ImportInfo represents a single import statement.

type ModuleResolver Uses

type ModuleResolver struct {
    // contains filtered or unexported fields
}

ModuleResolver implements resolver for modules using the go command as little as feasible.

func (*ModuleResolver) ClearForNewMod Uses

func (r *ModuleResolver) ClearForNewMod()

func (*ModuleResolver) ClearForNewScan Uses

func (r *ModuleResolver) ClearForNewScan()

type Options Uses

type Options struct {
    Env *ProcessEnv // The environment to use. Note: this contains the cached module and filesystem state.

    // LocalPrefix is a comma-separated string of import path prefixes, which, if
    // set, instructs Process to sort the import paths with the given prefixes
    // into another group after 3rd-party packages.
    LocalPrefix string

    Fragment  bool // Accept fragment of a source file (no package statement)
    AllErrors bool // Report all errors (not just the first 10 on different lines)

    Comments  bool // Print comments (true if nil *Options provided)
    TabIndent bool // Use tabs for indent (true if nil *Options provided)
    TabWidth  int  // Tab width (8 if nil *Options provided)

    FormatOnly bool // Disable the insertion and deletion of imports
}

Options is golang.org/x/tools/imports.Options with extra internal-only options.

type PackageExport Uses

type PackageExport struct {
    Fix     *ImportFix
    Exports []string
}

A PackageExport is a package and its exports.

type ProcessEnv Uses

type ProcessEnv struct {
    GocmdRunner *gocommand.Runner

    BuildFlags []string
    ModFlag    string
    ModFile    string

    // Env overrides the OS environment, and can be used to specify
    // GOPROXY, GO111MODULE, etc. PATH cannot be set here, because
    // exec.Command will not honor it.
    // Specifying all of RequiredGoEnvVars avoids a call to `go env`.
    Env map[string]string

    WorkingDir string

    // If Logf is non-nil, debug logging is enabled through this function.
    Logf func(format string, args ...interface{})
    // contains filtered or unexported fields
}

ProcessEnv contains environment variables and settings that affect the use of the go command, the go/build package, etc.

func (*ProcessEnv) CopyConfig Uses

func (e *ProcessEnv) CopyConfig() *ProcessEnv

CopyConfig copies the env's configuration into a new env.

func (*ProcessEnv) GetResolver Uses

func (e *ProcessEnv) GetResolver() (Resolver, error)

type Resolver Uses

type Resolver interface {
    ClearForNewScan()
    // contains filtered or unexported methods
}

A Resolver does the build-system-specific parts of goimports.
