Documentation is available in homepage.
If you installed EPUB Parser by gem command, you can also generate documentaiton yourself(rubygems-yardoc gem is needed):
$ gem install epub-parser $ gem yardoc epub-parser ... Files: 33 Modules: 20 ( 20 undocumented) Classes: 45 ( 44 undocumented) Constants: 31 ( 31 undocumented) Methods: 292 ( 88 undocumented) 52.84% documented YARD documentation is generated to: /path/to/gempath/ruby/2.2.0/doc/epub-parser-0.2.0/yardoc
It will show you path to generated documentation(/path/to/gempath/ruby/2.2.0/doc/epub-parser-0.2.0/yardoc here) at the end.
Or, generating by yardoc command is possible, too:
$ git clone https://gitlab.com/KitaitiMakoto/epub-parser.git $ cd epub-parser $ bundle install --path=deps $ bundle exec rake doc:yard ... Files: 33 Modules: 20 ( 20 undocumented) Classes: 45 ( 44 undocumented) Constants: 31 ( 31 undocumented) Methods: 292 ( 88 undocumented) 52.84% documented
Then documentation will be available in doc directory.
