Functions

func AssignMetadata

func AssignMetadata(metadata []map[string]interface{}, resources ...resource.Resource) error

AssignMetadata assigns the given metadata to those resources that supports updates and matching by wildcard given in `src` using `filepath.Match` with lower cased values. This assignment is additive, but the most specific match needs to be first. The `name` and `title` metadata field support shell-matched collection it got a match in. See https://golang.org/pkg/path/#Match

func ResourceCacheKey

func ResourceCacheKey(filename string) string

ResourceCacheKey converts the filename into the format used in the resource cache.

func ResourceKeyContainsAny

func ResourceKeyContainsAny(key string, partitions []string) bool

ResourceKeyContainsAny returns whether the key is a member of any of the given partitions.

This is used for resource cache invalidation.

func ResourceKeyPartitions

func ResourceKeyPartitions(filename string) []string

ResourceKeyPartitions resolves a ordered slice of partitions that is used to do resource cache invalidations.

We use the first directory path element and the extension, so:

a/b.json => "a", "json"
b.json => "json"

For some of the extensions we will also map to closely related types, e.g. "scss" will also return "sass".

Types

type ResourceCache

type ResourceCache struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

func (*ResourceCache) Contains

func (c *ResourceCache) Contains(key string) bool

func (*ResourceCache) DeletePartitions

func (c *ResourceCache) DeletePartitions(partitions ...string)

func (*ResourceCache) GetOrCreate

func (c *ResourceCache) GetOrCreate(key string, f func() (resource.Resource, error)) (resource.Resource, error)

func (*ResourceCache) GetOrCreateResources

func (c *ResourceCache) GetOrCreateResources(key string, f func() (resource.Resources, error)) (resource.Resources, error)

type ResourceSourceDescriptor

type ResourceSourceDescriptor struct {
	// TargetPaths is a callback to fetch paths's relative to its owner.
	TargetPaths func() page.TargetPaths

	// Need one of these to load the resource content.
	SourceFile         source.File
	OpenReadSeekCloser resource.OpenReadSeekCloser

	FileInfo os.FileInfo

	// If OpenReadSeekerCloser is not set, we use this to open the file.
	SourceFilename string

	Fs afero.Fs

	// The relative target filename without any language code.
	RelTargetFilename string

	// Any base paths prepended to the target path. This will also typically be the
	// language code, but setting it here means that it should not have any effect on
	// the permalink.
	// This may be several values. In multihost mode we may publish the same resources to
	// multiple targets.
	TargetBasePaths []string

	// Delay publishing until either Permalink or RelPermalink is called. Maybe never.
	LazyPublish bool
}

func (ResourceSourceDescriptor) Filename

func (r ResourceSourceDescriptor) Filename() string

type ResourceTransformation

type ResourceTransformation interface {
	Key() internal.ResourceTransformationKey
	Transform(ctx *ResourceTransformationCtx) error
}

ResourceTransformation is the interface that a resource transformation step needs to implement.

type ResourceTransformationCtx

type ResourceTransformationCtx struct {
	// The content to transform.
	From io.Reader

	// The target of content transformation.
	// The current implementation requires that r is written to w
	// even if no transformation is performed.
	To io.Writer

	// This is the relative path to the original source. Unix styled slashes.
	SourcePath string

	// This is the relative target path to the resource. Unix styled slashes.
	InPath string

	// The relative target path to the transformed resource. Unix styled slashes.
	OutPath string

	// The input media type
	InMediaType media.Type

	// The media type of the transformed resource.
	OutMediaType media.Type

	// Data data can be set on the transformed Resource. Not that this need
	// to be simple types, as it needs to be serialized to JSON and back.
	Data map[string]interface{}

	// This is used to publis additional artifacts, e.g. source maps.
	// We may improve this.
	OpenResourcePublisher func(relTargetPath string) (io.WriteCloser, error)
}

func (*ResourceTransformationCtx) AddOutPathIdentifier

func (ctx *ResourceTransformationCtx) AddOutPathIdentifier(identifier string)

AddOutPathIdentifier transforming InPath to OutPath adding an identifier, eg '.min' before any extension.

func (*ResourceTransformationCtx) PublishSourceMap

func (ctx *ResourceTransformationCtx) PublishSourceMap(content string) error

PublishSourceMap writes the content to the target folder of the main resource with the ".map" extension added.

func (*ResourceTransformationCtx) ReplaceOutPathExtension

func (ctx *ResourceTransformationCtx) ReplaceOutPathExtension(newExt string)

ReplaceOutPathExtension transforming InPath to OutPath replacing the file extension, e.g. ".scss"
