Because git is designed for source code, its default diff algorithm treats a line as the minimum indivisible unit.
I am trying to edit some markdown files that are word wrapped at column 80. Adding a sentence can cause the rest of the paragraph to be marked as changed.
Is there a way to have Git use a diff algorithm more suited to text? I need one that treats words or sentences as indivisible units rather than lines?
You might try git diff --word-diff instead.
$ git diff --word-diff
diff --git a/test.txt b/test.txt
index 54585bb..a8cd97e 100644

No newline at end of file
Maybe you are looking for word-diff
--word-diff[=
<mode>]Show a word diff, using the
<mode>to delimit changed words. By default, words are delimited by whitespace; see --word-diff-regex below. The<mode>defaults to plain, and must be one of:color
Highlight changed words using only colors. Implies --color.
plain
Show words as [-removed-] and {added}. Makes no attempts to escape the delimiters if they appear in the input, so the output may be ambiguous.
porcelain
Use a special line-based format intended for script consumption. Added/removed/unchanged runs are printed in the usual unified diff format, starting with a +/-/
character at the beginning of the line and extending to the end of the line. Newlines in the input are represented by a tilde ~ on a line of its own.none
Disable word diff again.
Note that despite the name of the first mode, color is used to highlight the changed parts in all modes if enabled.
Here is an example of customising this (from this question). As a default, --word-diff assumes a word to be a string of non-whitespace characters. The following command will consider a word consist of one of the following:
The command:
git diff --color-words --word-diff-regex='[A-z0-9_]+|[^[:space:]]'
