it is equivalent to using the \opt{right label} option. -\end{csdoc} - -The \meta{text} in these statements is the contents of the conclusion at the -root of the tree that the statements create. -It is typeset in math mode by default but any kind of formatting can be used -instead, using the \opt{template} option. -The \meta{label} text is formatted in horizontal text mode by default. - -Each proof tree has a vertical axis, used for alignment of successive steps. -The position of the axis is deduced from the text of the conclusion at the -root of the tree: if \meta{text} contains the alignment character \verb|&| -then the axis is set at that position, otherwise the axis is set at the center -of the conclusion text. -The \cs{infer} statement makes sure that the axis of the premiss is at the -same position as the axis of the conclusion. -If there are several premisses, it places the axis at the center between the -left of the leftmost conclusion and the right of the rightmost conclusion: - -\begin{example}{gobble=2} - \begin{prooftree} - \hypo{ &\vdash A, B, C } - \infer1{ A &\vdash B, C } - \infer1{ A, B &\vdash C } - \hypo{ D &\vdash E } - \infer2{ A, B, D &\vdash C, E } - \infer1{ A, B &\vdash C, D, E } - \infer1{ A &\vdash B, C, D, E } - \end{prooftree} -\end{example} - -\begin{csdoc}{\cs{ellipsis}\marg{label}\marg{text}} - Typeset vertical dots, with a label on the right, and a new conclusion. - No inference lines are inserted. - \begin{example}{gobble=4} - \begin{prooftree} - \hypo{ \Gamma &\vdash A } - \ellipsis{foo}{ \Gamma &\vdash A, B } - \end{prooftree} - \end{example} -\end{csdoc} - - -\subsection{Modifying proof trees} - -The following additional statements may be used to affect the format of the -last proof tree on the stack: - -\begin{csdoc}{\cs{rewrite}\marg{code}} - Rewrite the proof while preserving its size and alignment. The \meta{code} - is typeset in horizontal mode, with the following control sequences defined: - \begin{itemize} - \item \cs{treebox} is a box register that contains the original material, - \item \cs{treemark}\marg{name} expands as the position of a given mark with - respect to the left of the box. - \end{itemize} - A simple use of this statement is to change the color of a proof tree: - \begin{example}{gobble=4} - \begin{prooftree} - \hypo{ \Gamma, A &\vdash B } - \infer1[abs]{ \Gamma &\vdash A\to B } - \rewrite{\color{red}\box\treebox} - \hypo{ \Gamma \vdash A } - \infer2[app]{ \Gamma \vdash B } - \end{prooftree} - \end{example} - Note the absence of spaces inside the call to \cs{rewrite}, because spaces - would affect the position of the tree box. - Note also that explicit use of \cs{treebox} is required to actually draw the - subtree. - Not using it will effectively not render the subtree, while still reserving - its space in the enclosing tree: - \begin{example}{gobble=4} - \begin{prooftree} - \hypo{ \Gamma, A &\vdash B } - \infer1[abs]{ \Gamma &\vdash A\to B } - \rewrite{} - \hypo{ \Gamma \vdash A } - \infer2[app]{ \Gamma \vdash B } - \end{prooftree} - \end{example} - This kind of manipulation is useful for instance in conjunction with the - \package{beamer} package to allow revealing subtrees of a proof tree - progressively in successive slides of a given frame. -\end{csdoc} - -\begin{csdoc}{\cs{delims}\marg{left}\marg{right}} - Put left and right delimiters around the whole sub-proof, without changing - the alignment (the spacing is affected by the delimiters, however). - The \meta{left} text must contain an opening occurrence of \cs{left} and the - \meta{right} text must contain a matching occurrence of \cs{right}. - For instance, \verb|\delims{\left(}{\right)}| will put the - sub-proof between parentheses. - \begin{example}{gobble=4} - \begin{prooftree} - \hypo{ A_1 \vee \cdots \vee A_n } - \hypo{ [A_i] } - \ellipsis{}{ B } - \delims{ \left( }{ \right)_{1\leq i\leq n} } - \infer2{ B } - \end{prooftree} - \end{example} -\end{csdoc} - -\section{Options} -\label{sec:options} - -The formatting of trees, conclusion texts and inference rules is affected by -options, specified using the \LaTeX3 key-value system. -All options are in the \lit{ebproof} module in the key tree. -They can be set locally for a proof tree or for a single statement using -optional arguments in the associated commands. - -\begin{csdoc}{\cs{ebproofset}\marg{options}} - Set some options. - The options will apply in the current scope; using this in preamble will - effectively set options globally. - Specific options may also be specified for each proof tree and for each - statement in a proof tree, using optional arguments. -\end{csdoc} - -\subsection{General shape} - -The options in this section only make sense at the global level and at the -proof level. -Changing the proof style inside a \lit{proof} environment has undefined -behaviour. -

-\begin{csdoc}{\opt{center=}\meta{boolean}} - If set to \lit{true}, the tree produced by the \env{prooftree} environment - will be vertically centered around the text line. - If set to \lit{false}, the base line of the tree will be the base line of -

-\subsection{Shape of inference lines} - -\begin{csdoc}{\opt{rule style=}\meta{name}} - Set the shape of inference lines. - The following values are provided: - \begin{csdoc}{\opt{simple}} - A simple horizontal rule is drawn. - This is the default style. - \end{csdoc} - \begin{csdoc}{\opt{no rule}} - No inference line is drawn. - A single space of the length of \lit{rule margin} is inserted. - \end{csdoc} - \begin{csdoc}{\opt{double}} - A double line is drawn. - \end{csdoc} - \begin{csdoc}{\opt{dashed}} - A single dashed line is drawn. - \end{csdoc} - The precise rendering is influenced by parameters specified below. - Arbitrary new shapes can defined using the \lit{rule code} option described -

-\begin{example}{gobble=2} - \begin{prooftree} - \hypo{ \Gamma &\vdash A \to B } - \infer[no rule]1{ \Gamma &\vdash {!A} \multimap B } - \hypo{ \Delta &\vdash A } - \infer[rule thickness=2pt]1{ \Delta &\vdash {!A} } -

The space between dashes in the \lit{dashed} rule style. - It is \lit{0.3em} by default. -\end{csdoc} - -\begin{csdoc}{\opt{rule code=}\meta{code}} - This option is used to define an arbitrary shape for rules. - The \meta{code} is used to render the rule, it is executed in vertical mode - in a \cs{vbox} whose \cs{hsize} is set to the width of the rule. - Margins above and below are inserted automatically (they can be removed by - setting \lit{rule margin} to \lit{0pt}). - - \begin{example}{gobble=4} - \begin{prooftree}[rule code={\hbox{\tikz - \draw[decorate,decoration={snake,amplitude=.3ex}] - (0,0) -- (\hsize,0);}}] - \hypo{ \Gamma &\vdash A } -

The default value for \opt{template} is simply \verb|$\inserttext$|, so that - conclusions are set in math mode. - The default values for \opt{left template} and \opt{right template} are - similar, with spacing assuming that a relation symbol is put near the - alignment mark, so that \verb|\infer1{A &\vdash B}| is spaced correctly. - - \begin{example}{gobble=4} - \begin{prooftree}[template=(\textbf\inserttext)] - \hypo{ foo } - \hypo{ bar } - \infer1{ baz } -

of the inference line. - Using the second optional argument in \cs{infer} is equivalent to setting - the \env{right label} option with the value of that argument. - - \begin{example}{gobble=4} - \begin{prooftree} - \hypo{ \Gamma, A &\vdash B } - \infer[left label=$\lambda$]1[abs] - { \Gamma &\vdash A\to B } - \hypo{ \Gamma \vdash A } - \infer[left label=@]2[app]{ \Gamma \vdash B } - \end{prooftree} - \end{example} -\end{csdoc} -\begin{csdoc}{% - \opt{left label template=}\meta{code} \\ - \opt{right label template=}\meta{code}} - Defines how rule labels are formatted. - The code is arbitrary \TeX\ code, composed in horizontal mode. - The macro \cs{inserttext} can be used to insert the actual label text, as - defined by the options above. - The default values are simply \cs{inserttext} so that labels are set in - plain text mode. -\end{csdoc} - -\begin{csdoc}{\opt{label separation=}\meta{dimension}} - The spacing between an inference lines and its labels. - The default value is \lit{0.5em}. -\end{csdoc} -\begin{csdoc}{\opt{label axis=}\meta{dimension}} - The height of the horizontal axis used for aligning the labels with the - rules. The default value is \lit{0.5ex}. -\end{csdoc} - - -\subsection{Style macros} -\label{sec:styles} - -The following commands allow for the definition of custom styles using the -basic style options, in a way similar to PGF's ``styles'' and \LaTeX3's -``meta-keys''. -This allows setting a bunch of options with the same values in many proofs -using a single definition. - -\begin{csdoc}{\cs{ebproofnewstyle}\marg{name}\marg{options}} - Define a new style option \meta{name} that sets the given \meta{options}. - - For instance, the following code defines a new option \opt{small} that sets - various parameters so that proofs are rendered smaller. - \begin{example}{gobble=4} - \ebproofnewstyle{small}{ - separation = 1em, rule margin = .5ex, - template = \footnotesize$\inserttext$ } - \begin{prooftree}[small] - \hypo{ \Gamma, A \vdash B } - \infer1{ \Gamma \vdash A\to B } - \hypo{ \Gamma \vdash A } \infer2{ \Gamma \vdash B } - \end{prooftree} - \end{example} -\end{csdoc} - -\begin{csdoc}{\cs{ebproofnewrulestyle}\marg{name}\marg{options}} - Define a new rule style. - The \meta{options} part includes options used to set how to draw rules in - the new style. - - The option \opt{rule code} is useful in this command as it allows to - define arbitrary rule styles. - For instance, the squiggly rule example above could be turned into a new - rule style \lit{zigzag} with the following code: - \begin{example}{gobble=4} - \ebproofnewrulestyle{zigzag}{ - rule code = {\hbox{\tikz - \draw[decorate,decoration={snake,amplitude=.3ex}] - (0,0) -- (\hsize,0);}}} - \begin{prooftree} - \hypo{ \Gamma &\vdash A } - \infer1{ \Gamma &\vdash A, \ldots, A } - \hypo{ \Delta, A, \ldots, A \vdash \Theta } - \infer[zigzag]2{ \Gamma, \Delta \vdash \Theta } - \end{prooftree} - \end{example} -\end{csdoc} - - -\section{License} - -This work may be distributed and/or modified under the -conditions of the \LaTeX\ Project Public License, either version 1.3 -of this license or (at your option) any later version. -The latest version of this license is in -\begin{center} - \url{http://www.latex-project.org/lppl.txt} -\end{center} -and version 1.3 or later is part of all distributions of \LaTeX\ -version 2005/12/01 or later. - -This work has the LPPL maintenance status `maintained'. - -The Current Maintainer of this work is Emmanuel Beffara. - -This work consists of the files \texttt{ebproof.sty} and \texttt{ebproof.tex}. - - -\section{History} - -This section lists the principal evolutions of the package, in reverse -chronological order. -\begin{description} -\item[Version 2.0] - A complete rewrite of the code using the \LaTeX3 programming environment. - The incompatible changes from the user's point of view are the following: - \begin{itemize} - \item Proof statements are now writtten in lowercase ({i.e.} \cs{Infer} is - now written \cs{infer} etc.) but the syntax is otherwise unchanged. - The old uppercase commands still work but produce a deprecation warning, - they will be removed in a future version. - \item New styles are now defined using \cs{ebproofnewstyle} and - \cs{ebproofnewrulestyle}. The previous method using PGF styles does not - work anymore (because PGF is not used anymore). - \end{itemize} - The new commands and options are the following: - \begin{itemize} - \item The statement \cs{rewrite} generalizes \cs{Alter}, - \item The option \opt{label axis} controls vertical alignment of labels. - \end{itemize} -\item[Version 1.1] - A bugfix release. - In \opt{template} options, one now uses \cs{inserttext} instead of \lit{\#1} - for the text arguments, which improves robustness. -\item[Version 1.0] - The first public release. -\end{description} - -\end{document} |
