It produces proofs in the format used in the +% textbook \href{http://lpl.stanford.edu/}{\textit{Language, Proof, +% and Logic}} by Dave Barker-Plummer, Jon Barwise, and John +% Etchemendy. The package was originally written by John +% Etchemendy. The current version incorporates changes by Dave +% Barker-Plummer and Richard Zach. +% +% \section{Fitch Proofs by Example} +% \label{sect:proofs-by-example} +% +% In this section we will describe how to typeset the Fitch-style +% natural deduction proof shown in figure~\ref{fig:example-proof}. +% This proof uses all of the macros that we have developed for +% typesetting proofs and therefore serves as a good illustration. +% +% \begin{figure} +% \fitchprf{}{ +% \subproof{\pline[1.]{\uni{x}{(Cube(x)\lif Small(x))}}}{ +% \subproof{\pline[2.]{\exi{x}{Cube(x)}}}{ +% \boxedsubproof[3.]{a}{Cube(a)}{ +% \pline[4.]{Cube(a)\lif Small(a)}[\lalle{1}]\\ +% \pline[5.]{Small(a)}[\life{4}{3}]\\ +% \pline[6.]{\exi{x}{Small(x)}}[\lexii{5}] +% } +% \pline[7.]{\exi{x}{Small(x)}}[\lexie{2}{3--6}] +% } +% \pline[8.]{\exi{x}{Cube(x)}\lif \exi{x}{Small(x)}}[\lifi{2--7}] +% } +% \pline[9.]{\brokenform{(\uni{x}{(Cube(x)\lif Small(x))}\lif}{ +% \formula{(\exi{x}{Cube(x)} \lif \exi{x}{Small(x)})}}}[\lifi{1--8}] +% } +% \caption{An Example Proof} +% \label{fig:example-proof} +% \end{figure} +% +% The commands for producing this proof are given in +% figure~\ref{fig:proof-eg-cmds}. This proof is a little hard to take +% in all at once, and so in the remainder of this section we will +% describe the development of this proof, which we hope is of use to +% readers. +% +%\begin{figure} +%\begin{verbatim} +% \fitchprf{}{ +% \subproof{\pline[1.]{\uni{x}{(Cube(x)\lif Small(x))}}}{ +% \subproof{\pline[2.]{\exi{x}{Cube(x)}}}{ +% \boxedsubproof[3.]{a}{Cube(a)}{ +% \pline[4.]{Cube(a)\lif Small(a)}[\lalle{1}]\\ +% \pline[5.]{Small(a)}[\life{4}{3}]\\ +% \pline[6.]{\exi{x}{Small(x)}}[\lexii{5}] +% } +% \pline[7.]{\exi{x}{Small(x)}}[\lexie{2}{3--6}] +% } +% \pline[8.]{\exi{x}{Cube(x)}\lif \exi{x}{Small(x)}}[\lifi{2--7}] +% } +% \pline[9.]{\brokenform{(\uni{x}{(Cube(x)\lif Small(x))}\lif}{ +% \formula{(\exi{x}{Cube(x)} \lif \exi{x}{Small(x)})}}}[\lifi{1--8}] +% } +% \end{verbatim} +% \caption{The commands for producing the proof of +% figure~\ref{fig:example-proof}} +% \label{fig:proof-eg-cmds} +% \end{figure} +% +% We recommend developing the commands to typeset a proof from the +% inside out, starting with the most deeply nested subproof. We also +% recommend ignoring justifications until the proof is complete, +% primarily for simplicity but also because the line numbers are not +% known until the complete proof structure is present. +% +% We begin by writing the lines of the innermost subproof (lines 3--6 +% of the main proof). +% +% \begin{quote} +% \begin{tabular}{ll} +% |\pline{Cube(a)}| & \formula{Cube(a)}\\ +% |\pline{Cube(a)\lif Small(a)}| & \formula{Cube(a)\lif Small(a)}\\ +% |\pline{Small(a)}| & \formula{Small(a)}\\ +% |\pline{\exi{x}{Small(x)}}| & \formula{\exi{x}{Small(x)}} +% \end{tabular} +% \end{quote} +% +% The macro |\pline| produces a single line of the proof. The +% mandatory argument to |\pline| is the formula to appear within the +% step. You will notice that we have used the macro |\lif| to produce +% an conditional arrow, and |\exi| to produce an existentially +% quantified formula. These are members of a suite of macros that we +% find convenient for producing formulae. These are described in +% section~\ref{sect:formulae}. +% +% The |\pline| macro may only be used inside a proof context. We +% construct such a context by using the |\fitchprf| macro. This macro +% has two mandatory arguments, corresponding to the premises and the +% body of the proof. Each argument is a list of lines, separated by a +% newline (|\\|) command. We therefore embed the lines of our example +% proof like this: +% +% \begin{verbatim} +% \fitchprf{\pline{Cube(a)}}{ +% \pline{Cube(a) \lif Small(a)}\\ +% \pline{Small(a)}\\ +% \pline{\exi{x}{Small(x)}} +% }\end{verbatim} +% +% Typesetting a document containing this command results in +% the proof: +% \begin{quote} +% \fitchprf{\pline{Cube(a)}}{ +% \pline{Cube(a) \lif Small(a)}\\ +% \pline{Small(a)}\\ +% \pline{\exi{x}{Small(x)}} +% } +% \end{quote} +% +% Our next step is to embed this proof as a subproof within the larger +% proof. This is simply achieved. We first change the use of +% |\fitchprf| to a |\subproof| command, and then treat this as a line +% of the body of another |\fitchprf| command. The result of doing +% this is: +% +% \begin{verbatim} +% \fitchprf{\pline{\exi{x}{Cube(x)}}}{ +% \subproof{\pline{Cube(a)}}{ +% \pline{Cube(a)\lif Small(a)}\\ +% \pline{Small(a)}\\ +% \pline{\exi{x}{Small(x)}} +% } +% \pline{\exi{x}{Small(x)}} +% }\end{verbatim} +% +% \noindent which yields the proof: +% +% \begin{quote} +% \fitchprf{\pline{\exi{x}{Cube(x)}}}{ +% \subproof{\pline{Cube(a)}}{ +% \pline{Cube(a)\lif Small(a)}\\ +% \pline{Small(a)}\\ +% \pline{\exi{x}{Small(x)}} +% } +% \pline{\exi{x}{Small(x)}} +% } +% \end{quote} +% +% \noindent The new outer |\fitchprf| has two elements in the second +% argument, one of which is the subproof that we just wrote and the +% second is a formula. As we embedded the subproof in the body of the +% main proof we changed the command from |\fitchprf| to |\subproof|, +% the definitions of these two macros are almost identical but for the +% adjustment of vertical spacing after the use of a |\subproof| +% command. Note that no |\\| command is required after the use of a +% |\subproof| command. +% +% Two further applications of this technique give us the command: +% +% \begin{verbatim} +% \fitchprf{}{ +% \subproof{\pline{\uni{x}{(Cube(x)\lif Small(x))}}}{ +% \subproof{\pline{\exi{x}{Cube(x)}}}{ +% \subproof{\pline{Cube(a)}}{ +% \pline{Cube(a)\lif Small(a)}\\ +% \pline{Small(a)}\\ +% \pline{\exi{x}{Small(x)}} +% } +% \pline{\exi{x}{Small(x)}} +% } +% \pline{\exi{x}{Cube(x)}\lif \exi{x}{Small(x)}} +% } +% \pline{\brokenform{(\uni{x}{(Cube(x)\lif Small(x))}\lif}{ +% \formula{(\exi{x}{Cube(x)} \lif \exi{x}{Small(x)})}}} +% } +% \end{verbatim} +% +% \noindent which produces the proof +% +% \begin{quote} +% \fitchprf{}{ +% \subproof{\pline{\uni{x}{(Cube(x)\lif Small(x))}}}{ +% \subproof{\pline{\exi{x}{Cube(x)}}}{ +% \subproof{\pline{Cube(a)}}{ +% \pline{Cube(a)\lif Small(a)}\\ +% \pline{Small(a)}\\ +% \pline{\exi{x}{Small(x)}} +% } +% \pline{\exi{x}{Small(x)}} +% } +% \pline{\exi{x}{Cube(x)}\lif \exi{x}{Small(x)}} +% } +% \pline{\brokenform{(\uni{x}{(Cube(x)\lif Small(x))}\lif}{ +% \formula{(\exi{x}{Cube(x)} \lif \exi{x}{Small(x)})}}} +% } +% \end{quote} +% +% Notice that the last line contains a long formula, and we have used +% the |\brokenform| command to typeset this formula. The +% |\brokenform| command takes two arguments, the first is the first +% part of the formula, which will be typeset left justified in the +% space available, while the second argument contains the remaining +% pieces of the formula which will appear in subsequent lines. These +% lines should be separated by uses of the |\\| command, and each line +% should (usually) be a |\formula|. These lines will be typeset right +% justified in the available space. +% +% \subsection{Adding Line Numbers} +% +% The |\pline| command takes an optional argument which is the number +% of the line within the proof. We can simply add these now that we +% have all of the lines of the proof. +% +% \begin{verbatim} +% \fitchprf{}{ +% \subproof{\pline[1.]{\uni{x}{(Cube(x)\lif Small(x))}}}{ +% \subproof{\pline[2.]{\exi{x}{Cube(x)}}}{ +% \subproof{\pline[3.]{Cube(a)}}{ +% \pline[4.]{Cube(a)\lif Small(a)}\\ +% \pline[5.]{Small(a)}\\ +% \pline[6.]{\exi{x}{Small(x)}} +% } +% \pline[7.]{\exi{x}{Small(x)}} +% } +% \pline[8.]{\exi{x}{Cube(x)}\lif \exi{x}{Small(x)}} +% } +% \pline[9.]{\brokenform{(\uni{x}{(Cube(x)\lif Small(x))}\lif}{ +% \formula{(\exi{x}{Cube(x)} \lif \exi{x}{Small(x)})}}} +% }\end{verbatim} +% \noindent which results in the proof: +% \begin{quote} +% \fitchprf{}{ +% \subproof{\pline[1.]{\uni{x}{(Cube(x)\lif Small(x))}}}{ +% \subproof{\pline[2.]{\exi{x}{Cube(x)}}}{ +% \subproof{\pline[3.]{Cube(a)}}{ +% \pline[4.]{Cube(a)\lif Small(a)}\\ +% \pline[5.]{Small(a)}\\ +% \pline[6.]{\exi{x}{Small(x)}} +% } +% \pline[7.]{\exi{x}{Small(x)}} +% } +% \pline[8.]{\exi{x}{Cube(x)}\lif \exi{x}{Small(x)}} +% } +% \pline[9.]{\brokenform{(\uni{x}{(Cube(x)\lif Small(x))}\lif}{ +% \formula{(\exi{x}{Cube(x)} \lif \exi{x}{Small(x)})}}} +% } +% \end{quote} +% +% In the eventual proof, a boxed constant is introduced at line~3. We +% can convert the simple subproof into a boxed subproof. We use the +% |\boxedsubproof| macro to achieve this. The conversion is +% straightforward, we replace the first argument of the |\subproof| +% command which was |{\pline[3.]{Cube(a)}}}| by the three arguments +% |[3.]{a}{Cube(a)}| obtaining +% +% \begin{verbatim} +% \boxedsubproof[3.]{a}{Cube(a)}{ +% \pline[4.]{Cube(a)\lif Small(a)}\\ +% \pline[5.]{Small(a)}\\ +% \pline[6.]{\exi{x}{Small(x)}} +% }\end{verbatim} +% +% \subsection{Adding Justifications} +% +% The final thing that we need to do to complete the desired proof is +% the addition of justifications. To produce a justified line we need +% to then add the optional justification argument. +% +% \begin{verbatim}\pline[5.]{Small(a)}[\ife{4}{3}]\end{verbatim} +% +% \noindent The \verb|\ife| macro produces a justification using the +% $\lif$-elimination rule of the logic. This is one of a suite of +% macros that we developed to produce justifications in a uniform +% manner. These are described in section~\ref{sect:justifications}. +% +% \subsection{Command Reference} +% +% The |\pline| command can be used to typeset proof lines. It takes +% the formula as a mandatory argument, and line number and +% justification as optional arguments: |\pline|\oarg{line +% number}\marg{formula}\oarg{justification}. The variant |\fpline| +% works the same, except it produces a focus slider. In case you want +% to typeset a line in an argument or proof that is not typeset as a +% formula (e.g., plain text), use the |\tline| command. It takes a +% line number as optional argument. +% +% \subsection{Obsolete Commands} +% +% The original version of |lplfitch| set lines of proofs using two +% separate macros, the |\nline| and |\jline| commands. They are +% superceded by the |\pline| command and are included for backward +% compatibility only. +% +% A numbered line is produced by |\nline|, with the optional argument +% the line number. A justified line is produced using the +% \verb|\jline| macro, which has one mandatory and one optional +% argument. The optional argument contains the justification, while +% the mandatory argument must contain {\em all} of the arguments +% previously given to \verb|\nline|. So the command +% +% \begin{verbatim}\nline[5.]{Small(a)}\end{verbatim} +% +% \noindent produces exactly the same output as +% +% \begin{verbatim}\jline{[5.]{Small(a)}}\end{verbatim} +% +% \noindent but notice that both the arguments to \verb|\nline| are +% passed within the single argument to \verb|\jline|. To produce a +% justified line using |\jline|, you would also include the +% justification as an optional argument, say, +% +% \begin{verbatim}\jline{[5.]{Small(a)}}[\life{2}{3}]\end{verbatim} +% +% \section{Logical Formulae} +% \label{sect:formulae} +% +% We set our formulae using sans-serif font and we also need to be in +% math mode because the use of logical connectives. The +% \verb|\formula| command takes a formula to set as its argument, and +% handles both font and mode change. If the LPL convention of sans-serif +% formulas is not desired, you can simly redefine |\formula| as +% \begin{verbatim}\renewcommand{\formula}[1]{\ensuremath{#1}}\end{verbatim} +% +% Many of the commands that follow require that they are used in a +% formula, or math, context. +% +% \subsection{Connectives} +% +% We introduce our own (usually) shorter names for logical +% connectives. All of these commands require a formula context. +% +% \begin{center} +% \begin{tabular}{lc} +% \bf Usage & \bf Output\\ +% \hline\\ +% \verb|\land| & \formula{\land}\\ +% \verb|\lor| & \formula{\lor}\\ +% \verb|\lif| & \formula{\lif}\\ +% \verb|\liff| & \formula{\liff}\\ +% \verb|\lnot| & \formula{\lnot}\\ +% \verb|\lfalse| & \formula{\lfalse}\\ +% \verb|\lall| & \formula{\lall}\\ +% \verb|\lis| & \formula{\lis} +% \end{tabular} +% \end{center} +% +% \subsection{Quantified Formulae} +% +% So that we don't have to think about spacing when setting quantified +% formulae, we defined the commands |\exi| and |\uni|. Use +% |\exi{x}{P(x)}| to obtain \formula{\exi{x}{P(x)}}, and +% |\uni{x}{\exi{y}{(P(x)\lif Q(x,y))}}| for +% \formula{\uni{x}{\exi{y}{(P(x)\lif Q(x,y))}}}, for example. |\exi| +% and |\uni| require a formula context. +% +% \section{Justifications} +% \label{sect:justifications} +% +% Here are the macros that we have developed to typeset justifications +% within a proof. These do not require a formula context. +% +% \begin{center} +% \begin{tabular}{ll} +% \bf Usage & \bf Output\\ +% \hline\\ +% |\landi{2, 3}| &\landi{2, 3}\\ +% |\lande{4}|&\lande{4}\\ +% |\lori{5}| & \lori{5}\\ +% |\lore{6}{7--9}{11--13}| &\lore{6}{7--9}{11--13}\\ +% |\lnoti{14--15}| &\lnoti{14-15}\\ +% |\lnote{16}| &\lnote{16}\\ +% |\lfalsei{17}{19}| &\lfalsei{17}{19}\\ +% |\lfalsee{20}|&\lfalsee{20}\\ +% |\lifi{21--25}| &\lifi{21--25}\\ +% |\life{27}{30}| &\life{27}{30}\\ +% |\liffi{33--37}{40-50}|&\liffi{33--37}{40--50}\\ +% |\liffe{55}{57}| &\liffe{55}{57}\\ +% |\reit{4}|&\reit{4}\\ +% |\eqi| &\eqi\\ +% |\eqe{7}{11}|&\eqe{7}{11}\\ +% |\lalli{9--12}|&\lalli{9--12}\\ +% |\lalle{13}|&\lalle{13}\\ +% |\lexii{15}| &\lexii{15}\\ +% |\lexie{17}{18-30}| &\lexie{17}{18--30}\\ +% \end{tabular} +% \end{center} +% +% \section{Other Macros} +% \label{sect:other-macros} +% +% \subsection{Arguments} +% +% When you want to typeset an argument, for example when setting an +% exercise requiring the proof of some conclusion from a collection of +% premises, you should use the |\fitcharg| command. This command +% takes two arguments, both mandatory, the premise lines which are set +% above the Fitch bar, and the conclusion lines, which go below. +% Here's an example. The argument +% +%\begin{quote} +% \fitcharg{\formula{P(a)}\\ \formula{Q(a)}}{\formula{S(a)}} +%\end{quote} +% +%\noindent is typeset by the command: +%\begin{verbatim}\fitcharg{ +% \formula{P(a)}\\ +% \formula{Q(a)} +% }{ +% \formula{S(a)} +% }\end{verbatim} +% \noindent Notice that multiple lines are separated by a use of the +% \LaTeX\ command |\\|. +% +% \subsection{Fitch Contexts} +% +% The |\fitchctx| command is used for setting proof fragments which do +% not include the horizontal Fitch bar. We use these, for example, +% when formally describing the inference rules of our logic. The +% command below, for example, typesets our description of the rule of +% conditional proof. +% +% Notice here that we use the command |\ellipsesline| to produce a +% line of the ``proof'' containing a vertical ellipses (using the +% |\pline{\vdots}| results in the ellipses not being centered on the +% line). +% +% Another new feature of this situation is the use of the |\fpline| +% command. This command works just like the |\pline| command and +% produces exactly what the |\pline| command would, except that a +% focus slider appears to the left of the Fitch bar in question. The +% |\fpline| command does not work in the argument lines of +% |\fitchprf| or |\fitcharg|. +% +% \begin{verbatim} +% \fitchctx{ +% \subproof{\pline[$n$.]{P}}{ +% \ellipsesline\\ +% \pline[$m$.]{Q} +% } +% \fpline{P \lif Q}[\lifi{$n$--$m$}] +% } +% \end{verbatim} +% +% \begin{quote} +% \fitchctx{ +% \subproof{\pline[$n$.]{P}}{ +% \ellipsesline\\ +% \pline[$m$.]{Q} +% } +% \fpline{P \lif Q}[\lifi{$n$--$m$}] +% } +% \end{quote} +% +% \section{Other Packages} +% +% Two other \LaTeX{} packages provide functionality to typeset +% Fitch-style proofs. They differ from |lplfitch| in that they set the +% line numbers close to the left edge of the proof, while |lplfitch| +% sets them close to the formula.
