Text to Ignore
This panel let you define the texts which can be ignored
Lines to ignore group
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 knowledge would be lost.
- Lines matching
This expression is matched against each line individually.
If you do not specify the
$, the match is done against any part of the line.
*: whitespaces are sets of characters containing only space and tabulation characters. End of line characters (CR/LF) are not considered as whitespaces.
- 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
\r, you will want to use :
(\r\n|\r|\n) to match all types of line endings
(Windows, Unix and Mac). Use the helper button to enter generic
characters or regular expressions constructions.
Portions to ignore inside lines group
- Ignored fixed columns
Enter here the list of columns that you'd like to ignore inside all lines of the text file. For example, use "1-10;15;25-" to ignore column 1 to 10 included, 15, then all columns from 25 to the end of lines. Columns excluded this way never cover the line terminator which is tested separately and which you can ignore by unchecking the "Match line terminators" options in the comparison options.
- Ignore spans with expression : Disabled, Matching, Not matching
Select Matching (or Not matching) to ignore (or respectively to consider only) in each line which matches the given expression at least once, the text covered to the expression. Use the helper button to enter generic characters or regular expressions constructions.
- Use sub-expression
Rather than ignoring or considering only the portion covered by the entire expression, these are the portions covered by any sub-expression which are ignored or considered.
