But as we have to restore this +%%% category code at the end of this macro file we store its former value +%%% in the control sequence |\CatUsCode|. This method is better than to +%%% use a group because not all macros have to be defined global this way. + +%%% Since somebody might use more modules from me, this cseqs might be +%%% defined already. + +%%% \beginprog +\ifx \CatEscape\undefined + \chardef\CatEscape=0 + \chardef\CatOpen=1 + \chardef\CatClose=2 + \chardef\CatIgnore=9 + \chardef\CatLetter=11 + \chardef\CatOther=12 + \chardef\CatActive=13 % is defined in Plain already + + \chardef\CatUsCode=\catcode`\_ +\fi + +\catcode`\_=\CatLetter % top level macro file +%%% \endprog + + +%%% \sect Let's regard the implementation strategy. Because +%%% the contents of one page is determined at (nearly) random places +%%% with an asynchronous invogation of the output routine, we can not +%%% give numbers to every footnote subsequently between output and +%%% output: a footnote at the top of a page will perhaps get a number +%%% before the output is triggered and there is no way to change this +%%% number. The problem is like forward references to text places and it +%%% is solved in a similar fashion. We need two \TeX{} runs to get the +%%% numbering right but this is acceptable (who's got a finished text +%%% after one run?!). In the first run we gather up in a file the +%%% information where the footnotes are standing and in the second run +%%% we use this information. + +%%% We must identify all footnotes if we write their numbers to the +%%% footnote file, so each footnote gets an unary name built with the +%%% counter |\foot_name_no|. The name is `|f@|\<nameno>', where \<nameno> +%%% is the footnote name number. This name building scheme has several +%%% disadvantages, e.g.\ the insertion of a new footnote destroys the +%%% knowledge of the former run about the following footnotes. If we would +%%% have some knowledge about the document type we are using and the macro +%%% set which is in effect we could insert other counters (e.g.\ the +%%% chapter numbers) as well. + + + +%%% \chap Determing the footnote numbers. + +%%% Let's start with the initialization of the macro +%%% set. We need a file descriptor, |\foot_file|, which we use for the +%%% file interaction. The name of the file is built from the job name and +%%% the suffix `|.fot|' (I hope that no macro package uses this suffix). +%%% The |\init_footnote| macro reads the contents +%%% of the footnote file if it exists (|\ifeof| returns true if the file +%%% doesn't exist). The description of the reading of this file +%%% (|\read_foot_file|) is deferred until we know the structure of the +%%% contents. After reading, the file is closed and we can open it for +%%% writing. For security, i.e.\ to have a defined minimal contents, we +%%% immediately write |\relax| to the file. In the end the macro defines +%%% itself to |\relax| to allow calling it again. + +%%% \beginprog +\newread\old_foot_file +\newwrite\foot_file +\def\foot_file_name{\jobname.fot\relax} +\def\init_footnote{% + \openin\old_foot_file\foot_file_name + \ifeof\old_foot_file \closein\old_foot_file + \else \closein\old_foot_file + \read_foot_file + \fi + \immediate\openout\foot_file\foot_file_name + \immediate\write\foot_file{\relax}% + \global\let\init_footnote\relax + } +%%% \endprog + + +%%% \sect Remember, that we use |\foot_name_no| for the generation of a +%%% name for each footnote. The actual number of the footnote mark is +%%% stored in |\c@footnote|, the \LaTeX{} footnote counter. + +%%% In the beginning of every footnote |\init_footnote| is called to +%%% guarantee that the handling is initialized (this especially means +%%% that the footnote numbers are read in by the first footnote). + +%%% \beginprog +\newcount\foot_name_no % for generating footnote mark names +%%% \endprog + + +%%% \sect It remains an open problem how to get the numbers there. The +%%% footnote numbering must be initialized to zero in the output routine +%%% and every footnote must increment this footnote number. The only +%%% thing that is expanded during the output process is the output +%%% routine itself and the |\write|'s, but the expanded tokens of +%%% |\write| are written out, not interpreted. Well, the idea is simple: +%%% We defer the counting to the second run and write the instructions +%%% that do this to the file. The counting is then done while reading +%%% the footnote file. + +%%% \noindent That means that the output routine adds entries like +%%% % +%%% \begin{quote} +%%% |\c@footnote = 0| +%%% \end{quote} +%%% % +%%% and every footnote adds an entry that looks like +%%% % +%%% \begin{quote} +%%% |\advance\c@footnote by 1|\\ +%%% |\xdef\csname f@|\<nameno> |\endcsname{\number\c@footnote}| +%%% \end{quote} +%%% % +%%% where \<nameno> is replaced by the current footnote name number. + + +%%% \sect The macro |\fnpp_next_footnote| determines the next footnote +%%% number and stores it in |\c@footnote|, the official \LaTeX{} footnote +%%% counter. This counter is used since |\footnotetext| constructs the +%%% mark in the footnote text from it. One can say that +%%% |\fnpp_next_footnote| is a non-typical way to step this counter, it's +%%% a series iterator instead of an incrementer like |\stepcounter|. + +%%% The expansion of |\foot_name_no| must not be postponed until |\output| +%%% time because there may be more footnotes coming on this page that'll +%%% increase this number. +%%% Therefore we first define the macro |\do_write| which contains the +%%% |\write| and the expanded tokens which are to be put out. Every token +%%% that should not be expanded is prefixed by |\string| (resulting in +%%% character tokens that represent the token name). A |\space| must be +%%% inserted to separate |\csname| from |f|. The |\xdef| in the (written) +%%% definition code of |f@|\<nameno> is needed because the footnote file +%%% will be read in within a group. + +%%% After writing the entry to the footnote file the number for this +%%% footnote is set to~0 if it is not already defined (from a previous +%%% run). + +%%% \beginprog +\def\fnpp_next_footnote{% + \init_footnote + \global\advance\foot_name_no\@ne + \edef\do_write{% + \write\foot_file{% + \string\advance\c@footnote\@ne + \string\expandafter\xdef + \string\csname\space f@\number\foot_name_no \endcsname{% + \string\number\c@footnote + }% + }% + }% + \do_write + \global\c@footnote 0\csname f@\number\foot_name_no \endcsname \relax + } +%%% \endprog + + +%%% \sect It remains the reading of the footnote file. We have to read in +%%% macros with names containing `|@|' characters. This will be done in +%%% horizontal mode, so we ignore lineends to discard undesired spaces. + +%%% \beginprog +\def\read_foot_file{% + \begingroup + \catcode`\@\CatLetter \catcode`\^^M\CatIgnore + \input \foot_file_name + \endgroup + } +%%% \endprog + + + + +%%% \chap Connection to the output routine. + +%%% We must write the footnote number reset code at the start of each new +%%% page. The most easy way to do this is to add an |\immediate\write| +%%% to the output routine. + +%%% The output routine has no associated hook. (It should, of course. This +%%% is no exotic wish.) So we have to add our code to it by redefining +%%% some cseq. In a former version we really rebound |\output|, but that +%%% was a leftover from the plain \TeX{} version. Then we had to check for +%%% special |\output| invocations, which column we're in, etc. Now we rely +%%% on some internals of \LaTeX{}: |\@outputpage| does the real ship out, +%%% we just prepend our write to the front. + +%%% The reset code must not be written when no footnote was given by now. +%%% We can check for the binding of |\init_footnote| to detect this, it's +%%% |\relax| after the first footnote. + +%%% \beginprog +\let\fnpp_orig_outputpage=\@outputpage +\def\@outputpage{% + \ifx \init_footnote\relax + \immediate\write\foot_file{\c@footnote\z@}% + \fi + \fnpp_orig_outputpage + } +%%% \endprog + + + + +%%% \chap The user interface. + +%%% Footnotes may be produced by |\footnote|, or by |\footnotemark| and +%%% |\footnotetext| (the former creates the mark, the latter the text with +%%% the last mark). All these tags have an optional argument, a number +%%% that shall be used to create the mark for this specific invocation. + +%%% We redefine only the handling of macro invocations without optional +%%% arguments. The original bindings are made available in the protected +%%% interface, in case footnotes are used for unusual things. (See the +%%% chunk on title matters below, for an example.) + +%%% \beginprog +\let\FnppOrigFootnote=\footnote % save original bindings +\let\FnppOrigFootnotemark=\footnotemark + +\def\footnote{% + \@ifnextchar[% % ] (Emacs) + \@xfootnote + {\fnpp_next_footnote \@xfootnote[\the\c@footnote]}% + } +\def\footnotemark{% + \@ifnextchar[% % ] (Emacs) + \@xfootnotemark + {\fnpp_next_footnote \@xfootnotemark[\the\c@footnote]}% + } +%%% \endprog + + +%%% \sect Footnote tags in minipages behave a bit differently: There +%%% |\footnote| and |\footnotetext| create minipage-local footnotes, +%%% whereas |\footnotemark| creates a `global' footnote mark. I.e., if one +%%% wants to make a footnote in a minipage that shall go on the page, one +%%% has to specify |\footnotemark| in the minipage and |\footnotetext| +%%% thereafter. |\footnotetext| uses the current value of the footnote +%%% counter, since we set it by |\fnpp_next_footnote|, everything will +%%% work. + +%%% \LaTeX{} makes a hook available to setup the minipage enviroment. But +%%% the hook is initialized in a way that their own hook-enhancement +%%% function does not work, we have to repair it first.

E.g., to mention +%%% affiliation or acknowledgements in title matters. This is done by +%%% |\thanks| that uses |\footnotemark| to construct the respective marks. +%%% The expansion of |\thanks| is done by |\maketitle| that resets the +%%% footnote counter afterwards. But that reset does not work with this +%%% package, as the footnote counter value is not used to determine the +%%% next one. + +%%% The most simple solution is to reset |\footnotemark| during the +%%% evaluation of |\maketitle|. We can do that in a group since all +%%% side-effects of |\maketitle| should be global anyhow. + +%%% \beginprog +\let\fnpp_orig_maketitle=\maketitle +\def\maketitle{% + \begingroup + \let\footnotemark\FnppOrigFootnotemark + \fnpp_orig_maketitle + \endgroup + } +%%% \endprog + + + + + +%%% \chap The end. + +%%% Well, after all we're finished with this module.
