Constructor Details

#initialize(collection, folder, options = {}) ⇒ Renderer

This is only going to render the HTML collection We presuppose that the bibdata of the document is equivalent to that of the collection, and that the flavour gem can sensibly process it. We may need to enhance metadata in the flavour gems isodoc/metadata.rb with collection metadata

Parameters:

  • xml (Metanorma::Collection) —

    input XML collection

  • folder (String) —

    input folder

  • options (Hash) (defaults to: {})

Options Hash (options):

  • :coverpage (String) —

    cover page HTML (Liquid template)

  • :format (Array<Symbol>) —

    list of formats (xml,html,doc,pdf)

  • :output_folder (String) —

    output directory

#update_xrefs(file, docid, internal_refs) ⇒ String

Resolves references to other files in the collection. Three routines:

  1. Eref to a document that has been split into multiple documents

(sectionsplit) are resolved to direct eref to the split document

  1. Indirect erefs to a file anchor in an unknown file in the collection

(bibitem[@type = ‘internal’] ) are resolved to direct eref to the containing document

  1. Direct erefs to other files in collection

(repo(current-metanorma-collection/x) are resolved to hyperlinks

Parameters:

  • file (String) —

    XML content

  • identifier (String) —

    docid

  • internal_refs (Hash{String=>Hash{String=>String}] schema name to anchor to filename) —

    nternal_refs [HashString=>Hash{String=>String] schema name to anchor to filename

Returns:

  • (String) —

    XML content
