Method: Ruber::DocumentProject::Backend#write

Defined in:
lib/ruber/document_project.rb

#write(opts) ⇒ Object

Works mostly as YamlSettingsBackend#write. If the only option to be written is the project name, the file isn’t created, if it doesn’t exist, and is deleted if it does exist. Also, if there are any obsolete files (see document_path=), they are deleted, too.

If no file name is associated with the backend (that is, if file returns an empty string), a SystemCall error (most likely, Errno::ENOENT) will be raised
