Whether to show word-granularity differences within diff hunks.
nil Never show fine differences.
t Show fine differences for the current diff hunk only.
all Show fine differences for all displayed diff hunks.
Whether to ignore whitespace changes in word-granularity differences.
Whether to adjust the width of tabs in diffs.
Determining the correct width can be expensive if it requires
opening large and/or many files, so the widths are cached in the
variable magit-diff--tab-width-cache. Set that to nil to invalidate
the cache.
nil Never adjust tab width. Use ‘tab-width’s value from the Magit
buffer itself instead.
t If the corresponding file-visiting buffer exits, then use
tab-width’s value from that buffer. Doing this is cheap, so this
value is used even if a corresponding cache entry exists.
always If there is no such buffer, then temporarily visit the file
to determine the value.
always, but don’t visit files larger than NUMBER
bytes.
Specify where to highlight whitespace errors.
See magit-diff-highlight-trailing,
magit-diff-highlight-indentation. The symbol t means in all
diffs, status means only in the status buffer, and nil means
nowhere.
nil Never highlight whitespace errors.
t Highlight whitespace errors everywhere.
uncommitted Only highlight whitespace errors in diffs showing
uncommitted changes. For backward compatibility status is treated
as a synonym.
Specify in what kind of lines to highlight whitespace errors.
t Highlight only in added lines.
both Highlight in added and removed lines.
all Highlight in added, removed and context lines.
Whether to highlight whitespace at the end of a line in diffs. Used
only when magit-diff-paint-whitespace is non-nil.
This option controls whether to highlight the indentation in case it
used the "wrong" indentation style. Indentation is only highlighted
if magit-diff-paint-whitespace is also non-nil.
The value is an alist of the form ((REGEXP . INDENT)...). The path
to the current repository is matched against each element in reverse
order. Therefore if a REGEXP matches, then earlier elements are not
tried.
If the used INDENT is tabs, highlight indentation with tabs. If
INDENT is an integer, highlight indentation with at least that many
spaces. Otherwise, highlight neither.
Whether to hide ^M characters at the end of a line in diffs.
This option specifies the functions used to highlight the hunk-internal region.
magit-diff-highlight-hunk-region-dim-outside overlays the outside of
the hunk internal selection with a face that causes the added and
removed lines to have the same background color as context lines.
This function should not be removed from the value of this option.
magit-diff-highlight-hunk-region-using-overlays and
magit-diff-highlight-hunk-region-using-underline emphasize the
region by placing delimiting horizontal lines before and after it.
Both of these functions have glitches which cannot be fixed due to
limitations of Emacs’ display engine. For more information see
https://github.com/magit/magit/issues/2758 ff.
Instead of, or in addition to, using delimiting horizontal lines,
to emphasize the boundaries, you may wish to emphasize the text
itself, using magit-diff-highlight-hunk-region-using-face.
In terminal frames it’s not possible to draw lines as the overlay and underline variants normally do, so there they fall back to calling the face function instead.
This option controls whether added and removed lines outside the
hunk-internal region only lose their distinct background color or
also the foreground color. Whether the outside of the region is
dimmed at all depends on magit-diff-highlight-hunk-region-functions.
This option specifies additional arguments to be used alongside
--stat.
The value is a list of zero or more arguments or a function that
takes no argument and returns such a list. These arguments are
allowed here: --stat-width, --stat-name-width,
--stat-graph-width and --compact-summary. Also see
the git-diff(1) manpage.
