diff

diff | d

show differences between commits

Show the differences between two commits. If only one commit is specified, show the differences between the specified commit and your working copy. If no commits are specified, show your pending changes.

Specify -c to see the changes in the specified commit relative to its parent.

By default, this command skips binary files. To override this behavior, specify -a to include binary files in the diff.

By default, diffs are shown using the unified diff format. Specify -g to generate diffs in the git extended diff format. For more information, see sl help diffs.

--from-path and --to-path allow diffing between directories. Files outside --from-path in the left side are ignored. See sl help directorybranching for more information.

sl diff might generate unexpected results during merges because it defaults to comparing against your working copy's first parent commit if no commits are specified.

Examples:

• compare a file in the current working directory to its parent:

sl diff foo.c

• compare two historical versions of a directory, with rename info:

sl diff --git -r 5be761874:431ec8e07 lib/

• get change stats relative to the last change on some date:

sl diff --stat -r "date('may 2')"

• diff all newly-added files that contain a keyword:

sl diff "set:added() and grep(GNU)"

• compare a revision and its parents:

sl diff -c 340f3fef5              # compare against first parent
sl diff -r 340f3fef5^:340f3fef5   # same using revset syntax
sl diff -r 340f3fef5^2:340f3fef5  # compare against the second parent

Returns 0 on success.
