Class: Horde_Text_Diff - X-Ref
| __construct($engine, $params) X-Ref |
| Computes diffs between sequences of strings. param: string $engine Name of the diffing engine to use. 'auto' param: array $params Parameters to pass to the diffing engine. |
| getDiff() X-Ref |
| Returns the array of differences. |
| countAddedLines() X-Ref |
| returns the number of new (added) lines in a given diff. return: integer The number of new lines |
| countDeletedLines() X-Ref |
| Returns the number of deleted (removed) lines in a given diff. return: integer The number of deleted lines |
| reverse() X-Ref |
| Computes a reversed diff. Example: <code> $diff = new Horde_Text_Diff($lines1, $lines2); $rev = $diff->reverse(); </code> return: Horde_Text_Diff A Diff object representing the inverse of the |
| isEmpty() X-Ref |
| Checks for an empty diff. return: boolean True if two sequences were identical. |
| lcs() X-Ref |
| Computes the length of the Longest Common Subsequence (LCS). This is mostly for diagnostic purposes. return: integer The length of the LCS. |
| getOriginal() X-Ref |
| Gets the original set of lines. This reconstructs the $from_lines parameter passed to the constructor. return: array The original sequence of strings. |
| getFinal() X-Ref |
| Gets the final set of lines. This reconstructs the $to_lines parameter passed to the constructor. return: array The sequence of strings. |
| trimNewlines(&$line, $key) X-Ref |
| Removes trailing newlines from a line of text. This is meant to be used with array_walk(). param: string $line The line to trim. param: integer $key The index of the line in the array. Not used. |
| _check($from_lines, $to_lines) X-Ref |
| Checks a diff for validity. This is here only for debugging purposes. |
