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 added in v0.57.0 

func ResourceCacheKey(filename string) string

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

func ResourceKeyContainsAny added in v0.57.0 

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 added in v0.57.0 

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 Image 

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

Image represents an image resource.

func (Image) Content

func (i *Image) Width() int

Width returns i's width.

func (*Image) WithNewBase 

func (i *Image) WithNewBase(base string) resource.Resource

WithNewBase implements the Cloner interface.

type Imaging 

type Imaging struct {
	// Default image quality setting (1-100). Only used for JPEG images.
	Quality int

	// Resample filter used. See https://github.com/disintegration/imaging
	ResampleFilter string

	// The anchor used in Fill. Default is "smart", i.e. Smart Crop.
	Anchor string
}

Imaging contains default image processing configuration. This will be fetched from site (or language) config.

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

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 added in v0.57.0 

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 {

}

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.

	// 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.

	// We may improve this.

type ResourceTransformationKey 

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

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 

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.

	*helpers.PathSpec

	OutputFormats output.Formats

	Logger *loggers.Logger

	TextTemplates tpl.TemplateParseFinder
