Whitespace

Define how the Diff Viewer should treat whitespaces.

• Do not ignore: white spaces are important, and all the differences are highlighted. This option is selected by default.

• Trim whitespaces: trim whitespaces if they appear in the end and at the beginning of a line (("\t", " ")).

  • If two lines differ in trailing whitespaces only, these lines are considered equal.

  • If two lines are different, trailing whitespaces are not highlighted in the By word mode.

• Ignore whitespaces: white spaces are not important, regardless of their location in the source code.

• Ignore whitespaces and empty lines: ignores whitespaces and empty lines. The following entities are ignored:

  • all whitespaces (as in the 'Ignore whitespaces' option)

  • all added or removed lines consisting of whitespaces only

  • all changes consisting of splitting or joining lines without changes to non-whitespace parts.

    For example, differences between a b c and a \n b c are not highlighted in this mode.

• Ignore imports and formatting: changes within import statements and whitespaces are ignored (whitespaces within String literals are respected though).

Highlighting mode

Select the way differences granularity is highlighted.

The available options are:

• Highlight words: modified words are highlighted

• Highlight lines: modified lines are highlighted

• Highlight split changes: if this option is selected, big changes are split into smaller changes.

  For example, A \n B and A X \n B X are treated as two changes instead of one.

• Highlight characters: modified symbols are highlighted

• Do not highlight: if this option is selected, the differences are not highlighted at all.

  Use the Do not highlight option when you work with the files that were significantly modified. In such cases, highlighting might introduce additional difficulties during a review.
