Specifying Revision Sets

    Mercurial supports a functional language for selecting a set of revisions.

    The language supports a number of predicates which are joined by infix
    operators. Parenthesis can be used for grouping.

    Identifiers such as branch names may need quoting with single or double
    quotes if they contain characters like "-" or if they match one of the
    predefined predicates.

    Special characters can be used in quoted identifiers by escaping them,
    e.g., "\n" is interpreted as a newline. To prevent them from being
    interpreted, strings can be prefixed with "r", e.g. "r'...'".

    There is a single prefix operator:

    "not x"
      Changesets not in x. Short form is "! x".

    These are the supported infix operators:

    "x::y"
      A DAG range, meaning all changesets that are descendants of x and
      ancestors of y, including x and y themselves. If the first endpoint is
      left out, this is equivalent to "ancestors(y)", if the second is left
      out it is equivalent to "descendants(x)".

      An alternative syntax is "x..y".

    "x:y"
      All changesets with revision numbers between x and y, both inclusive.
      Either endpoint can be left out, they default to 0 and tip.

    "x and y"
      The intersection of changesets in x and y. Short form is "x & y".

    "x or y"
      The union of changesets in x and y. There are two alternative short
      forms: "x | y" and "x + y".

    "x - y"
      Changesets in x but not in y.

    "x^n"
      The nth parent of x, n == 0, 1, or 2. For n == 0, x; for n == 1, the
      first parent of each changeset in x; for n == 2, the second parent of
      changeset in x.

    "x~n"
      The nth first ancestor of x; "x~0" is x; "x~3" is "x^^^".

    There is a single postfix operator:

    "x^"
      Equivalent to "x^1", the first parent of each changeset in x.

    The following predicates are supported:

    "adds(pattern)"
      Changesets that add a file matching pattern.

    "all()"
      All changesets, the same as "0:tip".

    "ancestor(single, single)"
      Greatest common ancestor of the two changesets.

    "ancestors(set)"
      Changesets that are ancestors of a changeset in set.

    "author(string)"
      Alias for "user(string)".

    "bisect(string)"
      Changesets marked in the specified bisect status:

      - "good", "bad", "skip": csets explicitly marked as good/bad/skip
      - "goods", "bads"      : csets topologicaly good/bad
      - "range"              : csets taking part in the bisection
      - "pruned"             : csets that are goods, bads or skipped
      - "untested"           : csets whose fate is yet unknown
      - "ignored"            : csets ignored due to DAG topology

    "bookmark([name])"
      The named bookmark or all bookmarks.

    "branch(string or set)"
      All changesets belonging to the given branch or the branches of the
      given changesets.

    "children(set)"
      Child changesets of changesets in set.

    "closed()"
      Changeset is closed.

    "contains(pattern)"
      Revision contains a file matching pattern. See "hg help patterns" for
      information about file patterns.

    "date(interval)"
      Changesets within the interval, see "hg help dates".

    "desc(string)"
      Search commit message for string. The match is case-insensitive.

    "descendants(set)"
      Changesets which are descendants of changesets in set.

    "draft()"
      Changeset in draft phase.

    "file(pattern)"
      Changesets affecting files matched by pattern.

    "filelog(pattern)"
      Changesets connected to the specified filelog.

    "first(set, [n])"
      An alias for limit().

    "follow([file])"
      An alias for "::." (ancestors of the working copy's first parent). If a
      filename is specified, the history of the given file is followed,
      including copies.

    "grep(regex)"
      Like "keyword(string)" but accepts a regex. Use "grep(r'...')" to ensure
      special escape characters are handled correctly. Unlike
      "keyword(string)", the match is case-sensitive.

    "head()"
      Changeset is a named branch head.

    "heads(set)"
      Members of set with no children in set.

    "id(string)"
      Revision non-ambiguously specified by the given hex string prefix.

    "keyword(string)"
      Search commit message, user name, and names of changed files for string.
      The match is case-insensitive.

    "last(set, [n])"
      Last n members of set, defaulting to 1.

    "limit(set, [n])"
      First n members of set, defaulting to 1.

    "matching(revision [, field])"
      Changesets in which a given set of fields match the set of fields in the
      selected revision or set.

      To match more than one field pass the list of fields to match separated
      by spaces (e.g. "author description").

      Valid fields are most regular revision fields and some special fields.

      Regular revision fields are "description", "author", "branch", "date",
      "files", "phase", "parents", "substate" and "user". Note that "author"
      and "user" are synonyms.

      Special fields are "summary" and "metadata": "summary" matches the first
      line of the description. "metadata" is equivalent to matching
      "description user date" (i.e. it matches the main metadata fields).

      "metadata" is the default field which is used when no fields are
      specified. You can match more than one field at a time.

    "max(set)"
      Changeset with highest revision number in set.

    "merge()"
      Changeset is a merge changeset.

    "min(set)"
      Changeset with lowest revision number in set.

    "modifies(pattern)"
      Changesets modifying files matched by pattern.

    "outgoing([path])"
      Changesets not found in the specified destination repository, or the
      default push location.

    "p1([set])"
      First parent of changesets in set, or the working directory.

    "p2([set])"
      Second parent of changesets in set, or the working directory.

    "parents([set])"
      The set of all parents for all changesets in set, or the working
      directory.

    "present(set)"
      An empty set, if any revision in set isn't found; otherwise, all
      revisions in set.

      If any of specified revisions is not present in the local repository,
      the query is normally aborted. But this predicate allows the query to
      continue even in such cases.

    "public()"
      Changeset in public phase.

    "remote([id [,path]])"
      Local revision that corresponds to the given identifier in a remote
      repository, if present. Here, the '.' identifier is a synonym for the
      current local branch.

    "removes(pattern)"
      Changesets which remove files matching pattern.

    "rev(number)"
      Revision with the given numeric identifier.

    "reverse(set)"
      Reverse order of set.

    "roots(set)"
      Changesets in set with no parent changeset in set.

    "secret()"
      Changeset in secret phase.

    "sort(set[, [-]key...])"
      Sort set by keys. The default sort order is ascending, specify a key as
      "-key" to sort in descending order.

      The keys can be:

      - "rev" for the revision number,
      - "branch" for the branch name,
      - "desc" for the commit message (description),
      - "user" for user name ("author" can be used as an alias),
      - "date" for the commit date

    "tag([name])"
      The specified tag by name, or all tagged revisions if no name is given.

    "user(string)"
      User name contains string. The match is case-insensitive.

    New predicates (known as "aliases") can be defined, using any combination
    of existing predicates or other aliases. An alias definition looks like:

      <alias> = <definition>

    in the "revsetalias" section of a Mercurial configuration file. Arguments
    of the form "$1", "$2", etc. are substituted from the alias into the
    definition.

    For example,

      [revsetalias]
      h = heads()
      d($1) = sort($1, date)
      rs($1, $2) = reverse(sort($1, $2))

    defines three aliases, "h", "d", and "rs". "rs(0:tip, author)" is exactly
    equivalent to "reverse(sort(0:tip, author))".

    Command line equivalents for "hg log":

      -f    ->  ::.
      -d x  ->  date(x)
      -k x  ->  keyword(x)
      -m    ->  merge()
      -u x  ->  user(x)
      -b x  ->  branch(x)
      -P x  ->  !::x
      -l x  ->  limit(expr, x)

    Some sample queries:

    - Changesets on the default branch:

        hg log -r "branch(default)"

    - Changesets on the default branch since tag 1.5 (excluding merges):

        hg log -r "branch(default) and 1.5:: and not merge()"

    - Open branch heads:

        hg log -r "head() and not closed()"

    - Changesets between tags 1.3 and 1.5 mentioning "bug" that affect
      "hgext/*":

        hg log -r "1.3::1.5 and keyword(bug) and file('hgext/*')"

    - Changesets committed in May 2008, sorted by user:

        hg log -r "sort(date('May 2008'), user)"

    - Changesets mentioning "bug" or "issue" that are not in a tagged release:

        hg log -r "(keyword(bug) or keyword(issue)) and not ancestors(tagged())"
