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