EPUBMaker produces EPUB file.
Array of content objects.
Parameter hash.
Message resource object.
Take YAML file
and return parameter hash.
# File lib/epubmaker/producer.rb, line 30 def Producer.load(file) raise "Can't open #{yamlfile}." if file.nil? || !File.exist?(file) return YAML.load_file(file) end
Construct producer object. params
takes initial parameter
hash. This parameters can be overriden by EPUBMaker#load or
EPUBMaker#merge_params. version
takes EPUB version (default is
2).
# File lib/epubmaker/producer.rb, line 44 def initialize(params=nil, version=nil) @contents = [] @params = {} @epub = nil @params["epubversion"] = version unless version.nil? @res = ReVIEW::I18n unless params.nil? merge_params(params) end end

Write colophon file to IO object wobj
.
# File lib/epubmaker/producer.rb, line 130 def colophon(wobj) s = @epub.colophon wobj.puts s if !s.nil? && !wobj.nil? end
Write container file to IO object wobj
.
# File lib/epubmaker/producer.rb, line 109 def container(wobj) s = @epub.container wobj.puts s if !s.nil? && !wobj.nil? end
Write cover file to IO object wobj
. If #params is defined, it will be
used for the cover image.
# File lib/epubmaker/producer.rb, line 117 def cover(wobj) type = (@params["epubversion"] >= 3) ? "cover" : nil s = @epub.cover(type) wobj.puts s if !s.nil? && !wobj.nil? end

Add informations of figure files in path
to contents array.
base
defines a string to remove from path name.

Take YAML file
and update parameter hash.
# File lib/epubmaker/producer.rb, line 36 def load(file) raise "Can't open #{yamlfile}." if file.nil? || !File.exist?(file) merge_params(@params.merge(YAML.load_file(file))) end

Write mimetype file to IO object wobj
.
# File lib/epubmaker/producer.rb, line 90 def mimetype(wobj) s = @epub.mimetype wobj.print s if !s.nil? && !wobj.nil? end

Write ncx file to IO object wobj
. indentarray
defines prefix string for each level.
# File lib/epubmaker/producer.rb, line 103 def ncx(wobj, indentarray=[]) s = @epub.ncx(indentarray) wobj.puts s if !s.nil? && !wobj.nil? end
Write opf file to IO object wobj
.
# File lib/epubmaker/producer.rb, line 96 def opf(wobj) s = @epub.opf wobj.puts s if !s.nil? && !wobj.nil? end
Produce EPUB file epubfile
. basedir
points the
directory has contents (default: current directory.) tmpdir
defines temporary directory.
# File lib/epubmaker/producer.rb, line 167 def produce(epubfile, basedir=nil, tmpdir=nil) current = Dir.pwd basedir = current if basedir.nil? _tmpdir = tmpdir.nil? ?

Write title file (copying) to IO object wobj
.
# File lib/epubmaker/producer.rb, line 124 def titlepage(wobj) s = @epub.titlepage wobj.puts s if !s.nil? && !wobj.nil? end
