125 | =head1 DESCRIPTION |
126 | |
127 | Text::Tradition is a library for representation and analysis of collated |
128 | texts, particularly medieval ones. A 'tradition' refers to the aggregation |
129 | of surviving versions of a text, generally preserved in multiple |
130 | manuscripts (or 'witnesses'). A Tradition object thus has one more more |
131 | Witnesses, as well as a Collation that represents the unity of all versions |
132 | of the text. |
133 | |
134 | =head1 METHODS |
135 | |
136 | =head2 new |
137 | |
138 | Creates and returns a new text tradition object. The following options are |
139 | accepted. |
140 | |
141 | General options: |
142 | |
143 | =over 4 |
144 | |
145 | =item B<name> - The name of the text. |
146 | |
147 | =back |
148 | |
149 | Initialization based on a collation file: |
150 | |
151 | =over 4 |
152 | |
153 | =item B<input> - The input format of the collation file. Can be one of the |
154 | following: |
155 | |
156 | =over 4 |
157 | |
158 | =item * Self - a GraphML format produced by this module |
159 | |
160 | =item * CollateX - a GraphML format produced by CollateX |
161 | |
162 | =item * CTE - a TEI XML format produced by Classical Text Editor |
163 | |
a731e73a |
164 | =item * JSON - an alignment table in JSON format, as produced by CollateX and other tools |
165 | |
331c2dbf |
166 | =item * KUL - a specific CSV format for variants, not documented here |
167 | |
168 | =item * TEI - a TEI parallel segmentation format file |
169 | |
170 | =item * Tabular - a comma- or tab-separated collation. Takes an additional |
171 | option, 'sep_char', which defaults to the tab character. |
172 | |
173 | =back |
174 | |
175 | =item B<file> - The name of the file that contains the data. One of 'file' |
176 | or 'string' should be specified. |
177 | |
178 | =item B<string> - A text string that contains the data. One of 'file' or |
179 | 'string' should be specified. |
180 | |
181 | =item B<base> - The name of a text file that contains the base text, to be |
182 | used with input formats that require it (currently only KUL). |
183 | |
184 | =back |
185 | |
186 | Initialization based on a list of witnesses [NOT YET IMPLEMENTED]: |
187 | |
188 | =over 4 |
189 | |
190 | =item B<witnesses> - A reference to an array of Text::Tradition::Witness |
191 | objects that carry the text to be collated. |
192 | |
193 | =item B<collator> - A reference to a collation program that will accept |
194 | Witness objects. |
195 | |
196 | =back |
197 | |
198 | =head2 B<witnesses> |
199 | |
200 | Return the Text::Tradition::Witness objects associated with this tradition, |
201 | as an array. |
202 | |
044d1e45 |
203 | =head2 B<witness>( $sigil ) |
204 | |
205 | Returns the Text::Tradition::Witness object whose sigil is $sigil, or undef |
206 | if there is no such object within the tradition. |
207 | |
331c2dbf |
208 | =head2 B<add_witness>( %opts ) |
209 | |
210 | Instantiate a new witness with the given options (see documentation for |
211 | Text::Tradition::Witness) and add it to the tradition. |
212 | |
044d1e45 |
213 | =head2 B<del_witness>( $sigil ) |
214 | |
215 | Delete the witness with the given sigil from the tradition. Returns the |
216 | witness object for the deleted witness. |
