func (ll *LibraryExecution) Eval(values *datavalues.Envelope, libraryValues []*datavalues.Envelope, librarySchemas []*datavalues.SchemaEnvelope) (*EvalResult, error)

Eval given the final data values (as the parameter values) runs this LibraryExecution, evaluating all templates in this library and then applying overlays over that result.

Returns the final set of Documents and output files. Returns an error if any template fails to evaluate, any overlay fails to apply, or if one or more "Envelopes" were not delivered/used.

func (*LibraryExecution) Schemas added in v0.48.0 

func (ll *LibraryExecution) Schemas(overlays []*datavalues.SchemaEnvelope) (*datavalues.Schema, []*datavalues.SchemaEnvelope, error)

Schemas calculates the final schema for the Data Values in this library by combining/overlaying the schema file(s) in the library and the passed-in overlays.

Returns this library's Schema and a slice of Schema intended for child libraries.

func (*LibraryExecution) Values added in v0.48.0 

func (ll *LibraryExecution) Values(valuesOverlays []*datavalues.Envelope, schema *datavalues.Schema) (*datavalues.Envelope, []*datavalues.Envelope, error)

Values calculates the final Data Values for this library by combining/overlaying defaults from the schema, the Data Values file(s) in the library, and the passed-in Data Values overlays. The final Data Values are validated using the validations annotated on a Data Value.

Returns this library's Data Values and a collection of Data Values addressed to child libraries. Returns an error if the overlay operation fails or the result over an overlay fails a schema check.

type LibraryExecutionContext added in v0.24.0 

type LibraryExecutionContext struct {
	Current *Library // the target library that will be executed/evaluated.
	Root    *Library // reference to the root library to support accessing "absolute path" loading of files.
}

LibraryExecutionContext holds the total set of inputs that are involved in a LibraryExecution.

type LibraryExecutionFactory added in v0.23.0 

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

LibraryExecutionFactory holds configuration for and produces instances of LibraryExecution's.

func NewLibraryExecutionFactory added in v0.23.0 

func NewLibraryExecutionFactory(ui ui.UI, templateLoaderOpts TemplateLoaderOpts, skipDataValuesValidation bool) *LibraryExecutionFactory

NewLibraryExecutionFactory configures a new instance of a LibraryExecutionFactory.

func (*LibraryExecutionFactory) New added in v0.23.0 

func (f *LibraryExecutionFactory) New(ctx LibraryExecutionContext) *LibraryExecution

New produces a new instance of a LibraryExecution, set with the configuration and dependencies of this factory.

func (*LibraryExecutionFactory) ThatSkipsDataValuesValidations added in v0.48.0 

func (f *LibraryExecutionFactory) ThatSkipsDataValuesValidations(skipDataValuesValidation bool) *LibraryExecutionFactory

ThatSkipsDataValuesValidations produces a new LibraryExecutionFactory identical to this one, except it might also skip running validation rules over Data Values.

If a LibraryExecutionFactory has already been configured to skip validations, calling this method with `true` has no effect. This stems from the assumption that the downstream user is the most informed whether validations ought to be run.

func (*LibraryExecutionFactory) WithTemplateLoaderOptsOverrides added in v0.48.0 

func (f *LibraryExecutionFactory) WithTemplateLoaderOptsOverrides(overrides TemplateLoaderOptsOverrides) *LibraryExecutionFactory

WithTemplateLoaderOptsOverrides produces a new LibraryExecutionFactory identical to this one, except it configures its TemplateLoader with the merge of the supplied TemplateLoaderOpts over this factory's configuration.

type LibraryModule struct {
	// contains filtered or unexported fields

func NewLibraryModule(libraryCtx LibraryExecutionContext,
	libraryExecutionFactory *LibraryExecutionFactory,

FindCompiledTemplate returns the template.CompiledTemplate that was produced from the file at "path".
