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 ResourceKeyPartition 

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 Image 

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

Image represents an image resource.

func (Image) Content 

func (l Image) Content() (interface{}, error)

func (Image) Data 

func (l Image) Data() interface{}

func (*Image) Fill 

func (i *Image) Fill(spec string) (*Image, error)

func (*Image) Fit 

func (i *Image) Fit(spec string) (*Image, error)

Fit scales down the image using the specified resample filter to fit the specified maximum width and height.

func (*Image) Height 

func (i *Image) Height() int

func (l Image) RelPermalink() string

func (*Image) Resize 

func (i *Image) Resize(spec string) (*Image, error)

Resize resizes the image to the specified width and height using the specified resampling filter and returns the transformed image. If one of width or height is 0, the image aspect ratio is preserved.

func (Image) ResourceType 

func (l Image) ResourceType() string

func (Image) String 

func (l Image) String() string

func (Image) Title 

func (l Image) Title() string

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 

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(partition, key string, f func() (resource.Resource, error)) (resource.Resource, error)

type ResourceSourceDescriptor 

type ResourceSourceDescriptor struct {
	// TargetPathBuilder is a callback to create target paths's relative to its owner.
	TargetPathBuilder func(base string) string

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

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

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

	// Any base path prepeneded to the permalink.
	// Typically the language code if this resource should be published to its sub-folder.
	URLBase 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() 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"

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.

type Spec 

type Spec struct {
	*helpers.PathSpec

	MediaTypes    media.Types
	OutputFormats output.Formats

	Logger *loggers.Logger

	TextTemplates tpl.TemplateParseFinder

	ResourceCache *ResourceCache
	FileCaches    filecache.Caches
	// contains filtered or unexported fields
}

func NewSpec 

func NewSpec(
	s *helpers.PathSpec,
	fileCaches filecache.Caches,
	logger *loggers.Logger,
