%% |
|||
%% Syntax as follows: |
|||
%% each line is of the form |
|||
%% \begin{center} |
|||
%% \meta{variables} |
|||
%% \meta{name} |
|||
%% \verb/\:/ \meta{formula} |
|||
%% \verb/\=/ \meta{reason} |
|||
%% \verb/\-/ \meta{use} |
|||
%% \verb/\\/ |
|||
%% \end{center} |
|||
%% where |
|||
%% \begin{itemize} |
|||
%% \item \meta{variables} is something like ``$x,y$'' --- |
|||
%% it's for variables declared at the beginning of $\intro\forall$- and |
|||
%% $\elim\exists$-boxes. |
|||
%% \item \meta{name} is a command \verb/\label{fred}/ which |
|||
%% defines \verb/fred/ to be the label text, which may be used anywhere |
|||
%% as \verb/\ref{fred}/ --- see {\em The \LaTeX book.} |
|||
%% Local labels are also available, using \macrowitharg\lbl{name} |
|||
%% or \verb/\"/\meta{name}\verb/"/; these obey the scoping rules of |
|||
%% the boxes. |
|||
%% You may also refer to the previous line as \verb/\ref{-}/. |
|||
%% \item \meta{formula} is the proposition being asserted. |
|||
%% \item \meta{reason} is \verb/\intro\land(\ref{john},\ref{mary})/ |
|||
%% or \verb/\elim\forall(\ref{jim})/. |
|||
%% \item \meta{use} is provided for linear logic, to record the step |
|||
%%% which uses this one. How this accords with theory I don't yet know. |
|||
%% \end{itemize} |
|||
%% Note that the parts are separated by \verb/\:/, \verb/\=/ and \verb/\\/; |
|||
%% these correspond to |
|||
%% \begin{center} |
|||
%% {\bf let } \meta{name} = \meta{expression} : \meta{type} |
|||
%% \end{center} |
|||
%% in a declarative language. |
|||
%% The \verb/\:/, \verb/\=/ and \verb/\-/ fields are optional and may occur |
|||
%% in any order. If any of them is repeated the last is taken. |
|||
%% If none of them is present the \meta{variables} field is also ignored. |
|||
%% |
|||
%% Proof {\em boxes\/} are ``wrapped up'' as follows: |
|||
%% \begin{itemize} |
|||
%%% \item the whole proof in \verb/\begin{proofbox}/...\verb/\end{proofbox}/; |
|||
%%% \item single-column boxes ($\intro\forall$, $\intro\imp$, $\elim\exists$), |
|||
%% in \verb/\[/...\verb/\]/. |
|||
%% \item multiple-column boxes are of two kinds: |
|||
%% \begin{itemize} |
|||
%%% \item separate ($\intro\land$) boxes: \verb/\(/...\verb/\*/...\verb/\)/. |
|||
%% \item stuck together ($\elim\lor$) boxes: |
|||
%% \verb/\(/...\verb/\+/...\verb/\)/. |
|||
%% \end{itemize} |
|||
%% \end{itemize} |
|||
%% You may put more than two columns in \verb/\(/...\verb/\)/ and even mix |
|||
%% the \verb/\+/ and \verb/\*/ separators. |
|||
%% |
|||
%% The whole proof is enclosed in \verb/\proofbox/...\verb/\endproofbox/ |
|||
%% or \verb/\begin{proofbox}/...\verb/\end{proofbox}/, but the \LaTeX\ |
|||
%% environment form {\em must not\/} be used for nested boxes. |
|||
%% |
|||
%% If the proof occurs in paragraph mode (ie in vertical or |
|||
%% unrestricted horizontal mode) then it is set as a display, using the |
|||
%% full width of the page. Otherwise it uses only the required width. |
|||
%% |
|||
%% A lot of the internals are potentially configurable, but there is not |
|||
%% yet a user interface suitable for doing this. This will be provided |
|||
%% in the next version. |
|||
%% |
|||
%% This is a {\em prototype\/} proof-box macro package; |
|||
%% the syntax and implementation may change. |
|||
%% It is {\tt boxproof.tex} in the \TeX\ system |
|||
%% (so just \verb/\input boxproof/). |
|||
%% |
|||
%% There are some examples in |
|||
%% \verb+~pt/utilities/proofs/proofboxeg.tex+ and |
|||
%% \verb+proofboxeg1.tex+. |
|||
%% |
|||
%% The prototype version was begun on 2 August 1991, the new one on |
|||
%% 4 June 1993. |

%% \verb/\intro\land/ $\intro\land$ \qquad |
|||
%% \end{quote} |
|||
\def\intro#1{{{#1}{\cal I}}}\def\elim#1{{{#1}{\cal E}}}%% |
|||
%% Recall that in \TeX\ the logical connectives and quantifiers are called |

%% \begin{center} |

%% \verb/\lor/ $\lor$\quad |

|||
%% \verb/\lnot/ $\lnot$\quad |

%% \verb/\forall/ $\forall$\quad |
|||
%% \verb/\exists/ $\exists$ |

%% \end{center} |
|||
%% The following provide macros for the \verb/\implies/ {\em relation\/} |
|||
%% and for the binary {\em operation\/} which yields the abstract |
|||
%% \verb/\implic/ation between formulae. |
|||
%% The point is that \TeX\ spaces them and breaks the lines differently: |
|||
%% \begin{center} |
|||
%% \verb/A\implies B/ $A\implies B$\quad{\em versus\/}\quad |
|||
%% \verb/A\implic B/ $A\implic B$ |

%% There are several notations for substitution. |

%% After writing $a[x:=b]$ throughout my book I~thought I~might change to |

%% \begin{quote} |

%% \verb/\renewcommand{\CtxtMor}{\plaincontextmorphism}/ |
