Functions

func AssignMetadata added in v0.36.1

func AssignMetadata(metadata []map[string]interface{}, resources ...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 ResourceKeyPartition added in v0.45.1

func ResourceKeyPartition(filename string) string

ResourceKeyPartition returns a partition name to allow for more fine grained cache flushes. It will return the file extension without the leading ".". If no extension, it will return "other".

Types

type Cloner

type Cloner interface {
	WithNewBase(base string) Resource
}

Cloner is an internal template and not meant for use in the templates. It may change without notice.

type ContentResource added in v0.45.1

type ContentResource interface {
	Resource

	// Content returns this resource's content. It will be equivalent to reading the content
	// that RelPermalink points to in the published folder.
	// The return type will be contextual, and should be what you would expect:
	// * Page: template.HTML
	// * JSON: String
	// * Etc.
	Content() (interface{}, error)
}

ContentResource represents a Resource that provides a way to get to its content. Most Resource types in Hugo implements this interface, including Page. This should be used with care, as it will read the file content into memory, but it should be cached as effectively as possible by the implementation.

	ResourceType() string

	// MediaType is this resource's MIME type.
	MediaType() media.Type

	// Name is the logical name of this resource. This can be set in the front matter
	// metadata for this resource. If not set, Hugo will assign a value.
	// This will in most cases be the base filename.
	// So, for the image "/some/path/sunset.jpg" this will be "sunset.jpg".
	// The value returned by this method will be used in the GetByPrefix and ByPrefix methods
	// on Resources.
	Name() string

	// Title returns the title if set in front matter. For content pages, this will be the expected value.
	Title() string

	// Resource specific data set by Hugo.
	// One example would be.Data.Digest for fingerprinted resources.
	Data() interface{}

	// 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.

ResourceTransformationKey are provided by the different transformation implementations. It identifies the transformation (name) and its configuration (elements). We combine this in a chain with the rest of the transformations with the target filename and a content hash of the origin to use as cache key.

func NewResourceTransformationKey added in v0.45.1

func NewResourceTransformationKey(name string, elements ...interface{}) ResourceTransformationKey

NewResourceTransformationKey creates a new ResourceTransformationKey from the transformation name and elements. We will create a 64 bit FNV hash from the elements, which when combined with the other key elements should be unique for all practical applications.

type Resources

type Resources []Resource

Resources represents a slice of resources, which can be a mix of different types. I.e. both pages and images etc.

func (Resources) ByType

func (r Resources) ByType(tp string) Resources

func (Resources) GetMatch added in v0.36.1

func (r Resources) GetMatch(pattern string) Resource

GetMatch finds the first Resource matching the given pattern, or nil if none found. See Match for a more complete explanation about the rules used.

func (Resources) Match added in v0.36.1

func (r Resources) Match(pattern string) Resources

Match gets all resources matching the given base filename prefix, e.g "*.png" will match all png files. The "*" does not match path delimiters (/), so if you organize your resources in sub-folders, you need to be explicit about it, e.g.: "images/*.png". To match any PNG image anywhere in the bundle you can do "**.png", and to match all PNG images below the images folder, use "images/**.jpg". The matching is case insensitive. Match matches by using the value of Resource.Name, which, by default, is a filename with path relative to the bundle root with Unix style slashes (/) and no leading slash, e.g. "images/logo.png". See https://github.com/gobwas/glob for the full rules set.
