hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...

diff repository (or selected files)

Show differences between revisions for the specified files.

Differences between files are shown using the unified diff format.

Note:

'hg diff' may generate unexpected results for merges, as it will default to comparing against the working directory's first parent changeset if no revisions are specified.

When two revision arguments are given, then changes are shown between those revisions. If only one revision is specified then that revision is compared to the working directory, and, when no revisions are specified, the working directory files are compared to its first parent.

Alternatively you can specify -c/--change with a revision to see the changes in that changeset relative to its first parent.

Without the -a/--text option, diff will avoid generating diffs of files it detects as binary. With -a, diff will generate a diff anyway, probably with undesirable results.

Use the -g/--git option to generate diffs in the git extended diff format. For more information, read 'hg help diffs'.

Examples:

compare a file in the current working directory to its parent:
```
hg diff foo.c
```
compare two historical versions of a directory, with rename info:
```
hg diff --git -r 1.0:1.2 lib/
```
get change stats relative to the last change on some date:
```
hg diff --stat -r "date('may 2')"
```
diff all newly-added files that contain a keyword:
```
hg diff "set:added() and grep(GNU)"
```

compare a revision and its parents:

hg diff -c 9353         # compare against first parent
hg diff -r 9353^:9353   # same using revset syntax
hg diff -r 9353^2:9353  # compare against the second parent

Returns 0 on success.
