const All = "all"

All represents all values for a build context element (GOOS or GOARCH).

const StringFieldMissing = "!MISSING"

StringFieldMissing is the value for string fields that are not present in a struct. We use it to distinguish a (possibly valid) empty string from a field that was never populated.

Functions

func CandidateModulePaths 

func CandidateModulePaths(fullPath string) []string

CandidateModulePaths returns the potential module paths that could contain the fullPath, from longest to shortest. It returns nil if no valid module paths can be constructed.

func CompareBuildContexts 

func CompareBuildContexts(c1, c2 BuildContext) int

CompareBuildContexts returns a negative number, 0, or a positive number depending on the relative positions of c1 and c2 in BuildContexts.

func IsGoPkgInPathElement 

func IsGoPkgInPathElement(p string) bool

IsGoPkgInPathElement reports whether p is an element of a gopkg.in path. It returns true if p has "gopkg.in" as a prefix, or the suffix is a major version, for example "yaml.v2".

func MajorVersionForModule 

func MajorVersionForModule(modulePath string) string

MajorVersionForModule returns the final "vN" from the module path, if any. It returns the empty string if the module path is malformed. Examples: 

"m.com" => ""
"m.com/v2" => "v2"
"gpkg.in/m.v1 = "v1"

func ReadFileLines 

func ReadFileLines(filename string) (lines []string, err error)

ReadFileLines reads and returns the lines from a file. Whitespace on each line is trimmed. Blank lines and lines beginning with '#' are ignored.

func SeriesPathAndMajorVersion 

func SeriesPathAndMajorVersion(modulePath string) (string, int)

SeriesPathAndMajorVersion splits modulePath into a series path and a numeric major version. If the path doesn't have a "vN" suffix, it returns 1. If the module path is invalid, it returns ("", 0).

func SeriesPathForModule 

func SeriesPathForModule(modulePath string) string

SeriesPathForModule returns the series path for the provided modulePath.

func Suffix 

func Suffix(fullPath, basePath string) string

Suffix returns the suffix of the fullPath. It assumes that basePath is a prefix of fullPath. If fullPath and basePath are the same, the empty string is returned.

func V1Path 

func V1Path(fullPath, modulePath string) string

V1Path returns the path for version 1 of the package whose import path is fullPath. If modulePath is the standard library, then V1Path returns fullPath.

func VCSHostWithThreeElementRepoName 

func VCSHostWithThreeElementRepoName(hostname string) bool

VCSHostWithThreeElementRepoName returns true when the hostname has three elements like hostname/account/project.

Types

type BuildContext 

type BuildContext struct {
	GOOS, GOARCH string
}

A BuildContext describes a build context for the Go tool: information needed to build a Go package. For our purposes, we only care about the information that affects documentation generated from the package.

func (BuildContext) Match 

func (pattern BuildContext) Match(target BuildContext) bool

Match reports whether its receiver, which acts like a pattern, matches its target, an ordinary BuildContext. In addition to the usual values, a pattern can have an empty GOOS or GOARCH, which means "match anything."

func (BuildContext) String 

func (b BuildContext) String() string

String returns a string formatted representation of the build context.

type DataSource 

type DataSource interface {

	// GetNestedModules returns the latest major version of all nested modules
	// given a modulePath path prefix.
	GetNestedModules(ctx context.Context, modulePath string) ([]*ModuleInfo, error)
	// GetUnit returns information about a directory, which may also be a
	// module and/or package. The module and version must both be known.
	// The BuildContext selects the documentation to read.
	GetUnit(ctx context.Context, pathInfo *UnitMeta, fields FieldSet, bc BuildContext) (_ *Unit, err error)
	// GetUnitMeta returns information about a path.
	GetUnitMeta(ctx context.Context, path, requestedModulePath, requestedVersion string) (_ *UnitMeta, err error)
	// GetModuleReadme gets the readme for the module.
	GetModuleReadme(ctx context.Context, modulePath, resolvedVersion string) (*Readme, error)
	// GetLatestInfo gets information about the latest versions of a unit and module.
	// See LatestInfo for documentation.
	GetLatestInfo(ctx context.Context, unitPath, modulePath string, latestUnitMeta *UnitMeta) (LatestInfo, error)

	// SearchSupport reports the search types supported by this datasource.
	SearchSupport() SearchSupport
	// Search searches for packages matching the given query.
	Search(ctx context.Context, q string, opts SearchOptions) (_ []*SearchResult, err error)
}

DataSource is the interface used by the frontend to interact with module data.

type Documentation 

type Documentation struct {
	// The values of the GOOS and GOARCH environment variables used to parse the
	// package.
	GOOS     string
	GOARCH   string
	Synopsis string
	Source   []byte // encoded ast.Files; see godoc.Package.Encode
	API      []*Symbol
}

Documentation is the rendered documentation for a given package for a specific GOOS and GOARCH.

func DocumentationForBuildContext 

func DocumentationForBuildContext(docs []*Documentation, bc BuildContext) *Documentation

DocumentationForBuildContext returns the first Documentation the list that matches the BuildContext, or nil if none does. A Documentation matches if its GOOS and GOARCH fields are the same as those of the BuildContext, or if the Documentation field is "all", or if the BuildContext field is empty. That is, empty BuildContext fields act as wildcards. So the zero BuildContext will match the first element of docs, if there is one.

func (*Documentation) BuildContext 

func (d *Documentation) BuildContext() BuildContext

BuildContext returns the BuildContext for d.

type Experiment 

type Experiment struct {

	// Name is the name of the feature.
	Name string

	// Rollout is the percentage of requests enrolled in the experiment.
	Rollout uint

	// Description provides a description of the experiment.
	Description string
}

Experiment holds data associated with an experimental feature for frontend or worker.

type FieldSet 

type FieldSet int64

A FieldSet is a bit set of struct fields. It is used to avoid reading large struct fields from the data store. FieldSet is also the type of the individual bit values. (Think of them as singleton sets.)

MinimalFields (the zero value) is the empty set. AllFields is the set containing every field.

FieldSet bits are unique across the entire project, because some types are concatenations (via embedding) of others. For example, a 

const (
	WithMain FieldSet = 1 << iota
	WithImports
	WithLicenses
)

FieldSet bits for fields that can be conditionally read from the data store. 

const AllFields FieldSet = -1

AllFields is the FieldSet that contains all fields. 

const MinimalFields FieldSet = 0

MinimalFields is the empty FieldSet.

	MinorModulePath string

	// UnitExistsAtMinor is whether the unit exists at the latest minor version
	// of the module
	UnitExistsAtMinor bool

	// MajorModulePath is the path of the latest module path in the series.
	// For example, in the module path "github.com/casbin/casbin", there
	// is another module path with a greater major version
	// "github.com/casbin/casbin/v3". This field will be
	// "github.com/casbin/casbin/v3" or the input module path if no later module
	// path was found.
	MajorModulePath string

	// MajorUnitPath is the path of the unit in the latest major version of the
	// module, if it exists. For example, if the module is M, the unit is M/U,
	// and the latest major version is 3, then is field is "M/v3/U". If the module version
	// at MajorModulePath does not contain this unit, then it is the module path."
	MajorUnitPath string
}

LatestInfo holds information about the latest versions and paths. The information is relative to a unit in a module.

type LatestModuleVersions

func (*ModuleInfo) SeriesPath 

func (v *ModuleInfo) SeriesPath() string

SeriesPath returns the series path for the module.

A series is a group of modules that share the same base path and are assumed to be major-version variants.

The series path is the module path without the version. For most modules, this will be the module path for all module versions with major version 0 or 1. For gopkg.in modules, the series path does not correspond to any module version.

Examples: The module paths "a/b" and "a/b/v2" both have series path "a/b". The module paths "gopkg.in/yaml.v1" and "gopkg.in/yaml.v2" both have series path "gopkg.in/yaml".
