% MULTINOTE (MUF) MACROS for LaTeX2e, version 1.11,
% written by Herman Haverkort, 13 may 1995
% See end of file for information on warranty, distribution etc.

\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{hhmuf}[1995/05/13 Multinote system]
\RequirePackage{hhqueue}[1995/02/14]
\RequirePackage{hhutils0}[1995/03/08]

% =============================================================================
% -  \muf...                 (to set footnotes)
%
%       \muf:{TEXT}          for a ordinary footnote
%       \muf LABEL:{TEXT}    for a footnote which is labelled LABEL,
%                            to make it possible to reuse the footnote
%                            later on by stating:
%       \muf LABEL:{}        which sets the previously defined footnote
%                            labelled LABEL.
%    Labels should not contain commas, periods or colons!
%    If you use the same footnote several times, the multinote macros try
%    to ensure that the actual footnote text appears at most once on
%    every page.
% =============================================================================

\long\def\muf#1:#2{\@covermufpunct{%
  \h@ifespecified{#1}{\@mufsymonly #1:{#2}\muftxtonly #1:}%
                     {\@mufsymonly tmp@:{#2}\muftxtonly tmp@:\muffire tmp@:}}}
% If no label is specified, a temporary label is used.

% =============================================================================
% -  \mufsym...              (to postpone the setting of footnote texts)
%
%    If you use \mufsym instead of \muf, only the footnote's marker will be
%    set. The footnote text itself will not be set until \muffin is called.
%    \mufsym's syntax is similar to \muf's: you can use \mufsym:{TEXT},
%    \mufsym LABEL:{TEXT} and \mufsym LABEL:{}. \mufsym is especially useful
%    for footnotes in `forbidden' environments, like tables and parboxes.
%    Just say \mufsym in the forbidden environment, and call \muffin as soon
%    as you get out of it.
% =============================================================================

\long\def\mufsym#1:#2{\@covermufpunct{%
  \h@ifespecified{#1}{\edef\@@@lab{#1}}%
                     {\stepcounter{@muftmps}\edef\@@@lab{tmp@\roman{@muftmps}}}%
  \h@enqueue{@@@lab}{mufs@postponed}%
  \@mufsymonly \@@@lab:{#2}}}
% If no label is specified, one of the temporary labels tmp@i, tmp@ii etc.
% is used. The label is appended to the list of postponed footnotes.

% =============================================================================
% -  \muffin                 (to set postponed footnote texts)
%
%    \muffin sets all footnote texts which were postponed by using \mufsym
%    since the last call to \muffin.
% =============================================================================

\def\muffin{{%
  \@muffin
  \setcounter{@muftmp}{0}%
  \@whilenum \value{@muftmp}<\value{@muftmps}\do
    {\stepcounter{@muftmp}\muffire tmp@\roman{@muftmp}:}%
  \setcounter{@muftmps}{0}}}
\def\@muffin{%
  \h@ifqnonempty{mufs@postponed}{%
    \h@getfirst{@@@lab}{mufs@postponed}%
    \muftxtonly \@@@lab:%
    \@muffin}}
% \muffin calls \@muffin to set alle postponed footnotes. Then it frees
% all temporary labels and the markers assigned to them.

% =============================================================================
% -  \mufoff
%
%    The \mufoff macro makes handling forbidden environments even easier
%    than \mufsym. This is the way to use it:
%    \begin{ForbiddenEnvironment}
%      \mufoff
%      Lots of bla, possibly containing calls to \muf with fingers itching
%      to set a footnote. However, \mufoff guarantees that those footnotes
%      will be postponed like \muf were \mufsym.
%    \end{ForbiddenEnvironment}
%    \muffin
%
%    Nesting several forbidden environments which all insist on calling
%    \mufoff and \muffin is no problem. \mufoff redefines \muffin to do
%    nothing, so that only the outer \muffin will result in an attempt
%    to set footnotes, and that is exactly what should be done.
% =============================================================================
% -  \mufoff[ENVIRONMENTNAME]
%
%    \mufoff[ENVIRONMENTNAME] makes handling forbidden environments even
%    easier than basic \mufoff en \muffin. Type \mufoff[ForbiddenEnvironment]
%    and all multinotes between \begin{ForbiddenEnvironment} and
%    \end{ForbiddenEnvironment} will be postponed to just after closing
%    the forbidden environment.
%    For example: if you type \mufoff[tabular] in the preamble of your
%    document, then \muf's in the tabular environment will be handled
%    correctly automatically. Because that is so useful I already included
%    it in this style file, like I did with \mufoff[array] and
%    \mufoff[eqnarray].

                            }}
% \muffire will free the footnote's label by emptying the footnote text,
% and free the footnote's marker by appending it to the footnote symbol
% queue \mufsyms_avail. Thus the available footnote symbols will usually be
% used in turn, which establishes some nice variation in the type-setting
% of your article, report or book.

% =============================================================================
% -  \mufsymonly...          (to set a footnote's marker without the text)
%
%    The same as \mufsym, except for the footnote text, which will _not_

     \@makemufmark{??}}}

% =============================================================================
% -  \muftxtonly LABEL:      (to set a footnote's text without its marker)
%
%    The footnote text will be set, but no marker will show up at the
%    reference point.
% =============================================================================

\def\muftxtonly#1:{{%
  \h@ifnonempty{mufgrp@#1}%
    {\edef\@tempa{\@arabic{\c@page}}\edef\@tempb{\@nameuse{mufpag@#1}}%
     \ifx\@tempa\@tempb\else
     \@mufinsert{\@nameuse{mufsym@#1}}{\@nameuse{muftxt@#1}}%

    {\PackageWarning{hhmuf}{Cannot type-set multinote `#1':\MessageBreak
                            it is not defined}}}}
% \muftxtonly checks if the identifier of the current page equals
% the page identifier which is stored for the footnote to be set.
% If so, the footnote is already set on this page, so it should not be set
% again. If not so, it is set, and the current page identifier is stored.

% =============================================================================
% -  \mufbegin{GROUP}        (to start a multinote group)
%
%    See \mufend for explanation
% =============================================================================

\def\mufbegin#1{%
  \muffin
  \stepcounter{@mufgrplevel}%
  \h@initqueue{mufgrp@\arabic{@mufgrplevel}}{}%
  \@namexdef{mufgrpname@\arabic{@mufgrplevel}}{#1}}
% \mufbegin increases the nesting level counter and initializes the list
% of footnote labels for the new level. It stores the group name for
% matching it with the \mufend later on.

% =============================================================================
% -  \mufend{GROUP}          (to end a multinote group)
%
%    \mufend sets all postponed footnotes (like \muffin), and then muffires
%    all footnotes which had been defined since the corresponding call to
%    \mufbegin{GROUP}. Thus \mufbegin and \mufend establish some kind of
%    footnote definition environment, called a mufgroup.
%    Mufgroups can be nested, but if you do nest them, nest them properly.
%    So this is not permitted:
%
%       \mufbegin{A}\mufbegin{B}\mufend{A}\mufend{B},
%
%    while this is OK:
%
%       \mufbegin{A}\mufbegin{B}\mufend{B}\mufend{A}.
%
%    Whenever you enter a new group, a \muffin is performed and then all
%    footnotes which have already been defined are frozen. You cannot fire
%    them until the new group is closed with \mufend. So the following is OK:
%
%       \mufhire F:{Foo}\mufbegin{B}\mufend{B}\muffire F:
%
%    while this is not:
%
%       \mufhire F:{Foo}\mufbegin{B}\muffire F:\mufend{B}
%
%    Whenever you are in a group, you cannot redefine footnotes which have
%    been defined already in some outer group, because in that case you
%    would have to muffire the footnote, which is not allowed. You cannot
%    even define a new footnote which is local to the group but gets the
%    same label as some footnote which has been defined in some outer group
%    (e.g. a global footnote). The muf macros are not that smart. So the
%    following is not allowed:
%
%       \mufhire F:{Foo}\mufbegin{A}\mufhire F:{bar}
%
%    If you have closed all the groups you had opened (or if you never
%    opened any), then you are in the outermost, nameless group. You can
%    close that group with \mufend{}. It will muffire all footnotes you
%    had defined, and automatically reopen a outermost nameless group.
%    So it is a kind of: \muffin \muffire ALL.

% \mufword defines the word which is used in references to multinotes.
% It is `footnote'; redefine it if you like, preferably by defining the
% appropriate language option (see below).
% =============================================================================

\def\mufword{footnote~}

% =============================================================================
% \@makemufword defines how to format a footnote's marker (in the text, not
% in the insertion at the foot of the page). Redefine it if you like.
% =============================================================================

\def\@makemufmark#1{\hbox{$^{#1}$}}

% =============================================================================
% by default \@covermufpunct will pull periods and commas following a
% footnote's marker under the marker. With some definitions of \@makemufmark
% this will not be desirable: \@covermufpunct should be redefined to
% \def\@covermufpunct{} then.
% =============================================================================

  \spacefactor=\@gsavsf\@gobble}

% =============================================================================
% \@makemuftext defines how to format a footnote. It takes two arguments:
% #1 is the footnote's marker; #2 is the footnote text. Redefine it if you like.
% =============================================================================

\providecommand{\smallunitindent}[1]{10pt}
% This is to prepare hhmuf for use with the hhtext class (when I write this it's
% still under construction). The hhtext class will provide a \smallunitindent
% macro with some self-scaling features.

% =============================================================================
% The following specifies the footnote markers which will be used for
% multinotes. You can replace it with your own specification if you like.
% Please note that it makes no sense to use symbols with a well-defined
% order: the muf macros will not respect it.
% To make it easier to choose out of the numerous possibilities for
% footnote markers I defined some sets of markers which can be selected by
% specification of the appropriate option. The recognized options are:
% -  black      8 black symbols                 (requires amssymb.sty)
% -  circlox   12 circle and box symbols        (requires amssymb.sty)
% -  fuss      10 miscellaneous symbols         (requires amssymb.sty)
% -  geometry  10 geometrical symbols           (requires amssymb.sty)
% -  misc      19 miscellaneous symbols (default)
% -  music      3 music symbols
% -  strokes    8 symbols made of thin strokes  (requires amssymb.sty)
% Take care that you do not select a set which is too small for your purposes.

% * FAILURES AND POSSIBLE CAUSES *
% ********************************
%
% ! Package hhmuf Warning: Refusing to redefine multinote `LABEL'.
% (hhmuf)                  Muffire it first.
%
%    If you defined a footnote labelled LABEL, using \muf, \mufsym,
%    \mufsymonly or \mufhire, you should call \muffire LABEL: before
%    defining another footnote having the same label.
%
%
% ! Package hhmuf Warning: Out of multinote symbols.
% (hhmuf)                  Using `?' instead.
%
%    A marker is assigned to each footnote which has been defined. Because
%    the number of markers is limited, you will run out of markers if
%    too many footnotes have been defined at the same time. To prevent this
%    from happening, use \muffire to undefine footnotes as soon as you
%    do not need them anymore.
%    Keep in mind that each call to \mufsym:{TEXT} (even without a explicit
%    label) reserves a marker, which will not be released until the
%    next call to \muffin, \mufbegin or \mufend.
%    Also each call to \muf:{TEXT} which is placed in a `forbidden' environment
%    protected by \mufoff reserves a marker, which will not be released until
%    the environment is closed.
%
%
% ! Package hhmuf Warning: Reference to undefined multinote `LABEL'.
%
% ! Package hhmuf Warning: Cannot type-set multinote `LABEL':
% (hhmuf)                  it is not defined.
%
% ! Package hhmuf Warning: Cannot muffire multinote `LABEL':
% (hhmuf)                  it is not defined.
%
%    Should be evident. If it is not, please check if you did not close
%    the group in which the multinote was defined already (using \mufend).
%    One other mistake you could have made, is calling \muffire LABEL:
%    somewhere between \mufsym LABEL:{OPTIONAL-TEXT} and the first \muffin
%    following it. This happens implicitely if you call \muffire LABEL:
%    somewhere between \muf LABEL:{OPTIONAL-TEXT} in a protected forbidden
%    environment and the closure of that environment.
%    Note that if the multinote LABEL is undefined, calling for example
%    \muf LABEL:{} results in two warnings: one for the in-text
%    multinote reference marker (`Reference to undefined...'), and another
%    for the type-setting of the footnote itself (`Cannot type-set...').
%
%
% ! Package hhmuf Warning: Reference to undefined multinote `tmp_'.
% (and similar messages)
%
%    You used \muf:{} or \mufsym:{}, which does not make any sense.
%
%
% ! Package hhmuf Warning: Multinote `LABEL' was defined at level 1,
% (hhmuf)                  so cannot muffire it at level 3.
% (and similar messages)
%
% Since you defined the multinote LABEL, you opened another group which
% is still open. It is not possible to undefine the multinote then.
% Muffire before opening the current group, or after closing it.
%
%
% ! Package hhmuf Warning: Refusing to end multinote group `GROUPA' by
% (hhmuf)                  \mufend{GROUPB}.
% (and similar messages)
%
% This warning should be caused by mismatched \mufbegins and \mufends.
% Remember mufgroups should be properly nested.
%
%
% - The footnote's marker appears all right, but the text is missing
%
%    Two possible causes:
%    1. You used \mufsym but forgot \muffin.
%    2. You used \muf, \muftxtonly or \muffin in some `forbidden'
%       environment. The constraints are the same as for ordinary
%       LaTeX footnotes, unless the environment is protected by
%       \mufoff[ENVIRONMENT-NAME].
%
%
% - A footnote text is set although it should not be there.
%
%    You probably forgot some \muffin some time ago, so that the footnote
%    texts, which should have been set by that \muffin, are set by a following
%    \muffin.
%
%
% - A footnote text appears twice on the same page.
%
%    LaTeX could have floated a identical footnote from the previous page to
%    this one which cannot be detected by the multinote macros.
%    Another possible cause is probably the multinote macros getting the
%    the page number of the in-text marker wrong. This problem is very
%    much like the inability to start the footnote numbering every page
%    (which - by the way - is no problem if you use multinotes, because
%    they use a shift-system for their numbering). This problem can be
%    solved, and probably will be solved as soon as I encounter it in
%    practice.
%    In both cases correct the error `manually' by using \mufsymonly once
%    instead of \muf or \mufsym, or by omitting a \muftxtonly.
%
%
% **************************************************
% * PROBLEMS TO BE SOLVED / EXTENSIONS TO BE MADE: *
% **************************************************
%
% -  The last mentioned failure.
% -  Enabling multinotes under minipages.
% -  A switch to force muf to set footnote texts at most once at
%    a pair of opposite pages.
