hg import [OPTION]... PATCH...

aliases: patch

import an ordered set of patches

Import a list of patches and commit them individually (unless --no-commit is specified).

Because import first applies changes to the working directory, import will abort if there are outstanding changes.

You can import a patch straight from a mail message. Even patches as attachments work (to use the body part, it must have type text/plain or text/x-patch). From and Subject headers of email message are used as default committer and commit message. All text/plain body parts before first diff are added to commit message.

If the imported patch was generated by "hg export", user and description from patch override values from message headers and body. Values given on command line with -m/--message and -u/--user override these.

If --exact is specified, import will set the working directory to the parent of each patch before applying it, and will abort if the resulting changeset has a different ID than the one recorded in the patch. This may happen due to character set problems or other deficiencies in the text patch format.

Use --bypass to apply and commit patches directly to the repository, not touching the working directory. Without --exact, patches will be applied on top of the working directory parent revision.

With -s/--similarity, hg will attempt to discover renames and copies in the patch in the same way as "hg addremove".

To read a patch from standard input, use "-" as the patch name. If a URL is specified, the patch will be downloaded from it. See "hg help dates" for a list of formats valid for -d/--date.


  • import a traditional patch from a website and detect renames:
    hg import -s 80
  • import a changeset from an hgweb server:
    hg import
  • import all the patches in an Unix-style mbox:
    hg import incoming-patches.mbox
  • attempt to exactly restore an exported changeset (not always possible):
    hg import --exact proposed-fix.patch

Returns 0 on success.
