hg export [OPTION]... [-o OUTFILESPEC] [-r] [REV]...

dump the header and diffs for one or more changesets

Print the changeset header and diffs for one or more revisions. If no revision is given, the parent of the working directory is used.

The information shown in the changeset header is: author, date, branch name (if non-default), changeset hash, parent(s) and commit comment.

Note:

'hg export' may generate unexpected diff output for merge changesets, as it will compare the merge changeset against its first parent only.

Output may be to a file, in which case the name of the file is given using a format string. The formatting rules are as follows:

"%%"
literal "%" character
"%H"
changeset hash (40 hexadecimal digits)
"%N"
number of patches being generated
"%R"
changeset revision number
"%b"
basename of the exporting repository
"%h"
short-form changeset hash (12 hexadecimal digits)
"%m"
first line of the commit message (only alphanumeric characters)
"%n"
zero-padded sequence number, starting at 1
"%r"
zero-padded changeset revision number

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

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

With the --switch-parent option, the diff will be against the second parent. It can be useful to review a merge.

Examples:

Returns 0 on success.
