Specifying Single Revisions

    Mercurial supports several ways to specify individual revisions.

    A plain integer is treated as a revision number. Negative integers are
    treated as sequential offsets from the tip, with -1 denoting the tip, -2
    denoting the revision prior to the tip, and so forth.

    A 40-digit hexadecimal string is treated as a unique revision identifier.

    A hexadecimal string less than 40 characters long is treated as a unique
    revision identifier and is referred to as a short-form identifier. A
    short-form identifier is only valid if it is the prefix of exactly one
    full-length identifier.

    Any other string is treated as a tag or branch name. A tag name is a
    symbolic name associated with a revision identifier. A branch name denotes
    the tipmost revision of that branch. Tag and branch names must not contain
    the ":" character.

    The reserved name "tip" is a special tag that always identifies the most
    recent revision.

    The reserved name "null" indicates the null revision. This is the revision
    of an empty repository, and the parent of revision 0.

    The reserved name "." indicates the working directory parent. If no
    working directory is checked out, it is equivalent to null. If an
    uncommitted merge is in progress, "." is the revision of the first parent.
