DiffStyle

DiffStyle

is an option for Diff and related functions that specifies styles to use when viewing changes.

Details

  • DiffStyleassoc can use the following keys to describe different elements of the diff result:
  • "Added"style for added elements
    "Changed"style for changed elements
    "Conflict"style for conflicts
    "NotChanged"style for elements that have not changed
    "Removed"style for removed elements
  • Color directives such as Red, as well as text specifications such as Bold or Small, can be given in place of options, just as in Style.
  • Using DiffStyle<|keyspec|> is effectively equivalent to replacing the diff elements specified by key with Style[diffelement,spec].
  • DiffStyle is applied after DefaultDiffStyle.

Examples

Basic Examples  (3)

Increase the font size of added characters:

Wolfram Language code: Diff["abc", "abcd", DiffStyle -> <|"Added" -> 24|>]

Italicize removed characters:

Wolfram Language code: Diff["abcdefg", "afg", DiffStyle -> <|"Removed" -> {Italic}|>]

Customize styles in a unified diff:

Wolfram Language code: Diff[{1, 2, 3}, {2, 3, 4}, "Unified", DiffStyle -> <| "Added" -> {Background -> LightBlue, FontColor -> Purple}, "Removed" -> {Background -> LightOrange, FontColor -> Red}, "NotChanged" -> {Background -> Purple, FontColor -> White}|>]
