Lines to Ignore

 

 

This panel let you define the lines which can be ignored during differentiation.
Currently lines are ignored after matching, it let's unchanged ignorable lines be matched and synchronize text accordingly. This strategy is usually much more efficient than ignoring "a priori" as this advance would be lost.

Lines matching

This expression is matched against each line individually. If you do not specify the ^ and/or $, the match is done against any part of the line.

Lines covered by multi-line expression

This expression is searched throughout the entire file, ignoring line ends, then lines entirely covered are ignored. In this expression the dot symbol (.) still does not match new-lines, you need to use the special \n and \r, you will want to use : (\r\n|\r|\n) to match all types of line endings (Windows, Unix and Mac).
