The Files Comparison preferences
panel is opened from menu and offers the following configurable preferences:
The Files Comparison Preferences Panel
- Default algorithm - The default algorithm
used for comparing files. The following options are available:
- Auto - Automatic selection of the diff algorithm,
based on the file content and its size.
- Characters - Computes the differences at character
- Words - Computes the differences at word level.
- Lines - Computes the differences at line level.
- Syntax aware - For the file types known by Oxygen XML Developer, this algorithm
computes the differences taking into consideration the syntax (the specific types of
tokens) of the documents.
- XML Fast - A diff algorithm well-suited for large XML
documents (tens of MB). Sacrifices accuracy in favor of speed.
- XML Accurate - XML-tuned diff algorithm. It favors
accuracy over speed.
- Algorithm strength - Controls the amount of resources
allocated to the application to perform the comparison. The algorithm stops
searching more differences when reaches the maximum allowed resources. A dialog is
shown when this limit is reached and partial results are displayed. Four settings
are available: Low, Medium (default),
High and Very High.
- Ignore Whitespaces - Ignoring whitespaces means that before
performing the comparison, the application normalizes the content (collapses any sequence of
whitespace characters (space, newline or tab characters) into a single space) and trims its
leading and trailing whitespaces.
Note: If the Ignore Whitespaces
check box is selected, comparing the a b sequence with a
b, Oxygen XML Developer finds
no differences, because after normalization, all whitespaces from the first sequence are
collapsed into a single space character. However, when comparing a b
with ab (no whitespace between a and
b), Oxygen XML Developer
signals a difference.
- XML Diff Options - This set of options
allows you to specify the types of XML nodes for which the differences will be
ignored (will not be reported) by the XML Fast and
XML Accurate algorithms.
- Merge adjacent differences - If checked, it considers two
adjacent differences as one when the differences are painted in the side-by-side
editors. If unchecked, every difference is represented separately.
- Mark end tags as different for modified elements - If
checked, end tags of modified elements are presented as differences too, otherwise
only the start tags are presented as differences.
- Ignore expansion state for empty elements - If checked, empty
elements in both expansion states are considered matched, that is
<element></element> are considered equal.
