By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19yy name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

It is based on +% \texttt{emp}~\cite{emp} since it follows a similar approach for \MP{} +% \cite{MP}. +% Nevertheless, it is arguable that complex \SK{} figures may be easier +% handled in a separate file. That is because it does not directly +% improve readability for ones source code to have the \SK{} code mixed +% with \LaTeX. But that's purely a matter of taste and complexity. To +% have \SK{} code in separate files be included in your build process +% you could do the following: +% \begin{enumerate} +% \item have your \SK{} code in a file, e.g. \emph{nice\_scene.sk} +% \item include the file \emph{nice\_scene.sk.tex} in your document +% source +% \item configure your build in a way to automatically call \SK{} on all +% \emph{\textasteriskcentered.sk} files, e.g in a Makefile:\newline +% { |for i in `ls *.sk`; do sketch -o "$$i.tex" "$$i"; done| } +% \end{enumerate} +% At least for less complex graphics it is more convenient to use \ESK{} +% and thus stay consistent more easily. +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \section{Usage} +% +% This chapter describes the different macros and environments provided +% by the \ESK{} package. The |esk| environment is the one that actually +% generates printable source code. Depending on what options have been +% specified with |\eskglobals| and |\eskaddtoglobals| this is TikZ or +% PSTricks code. If an |esk| environment is encountered, it gets +% processed the following way: +% \begin{enumerate} +% \item \label{proc:gen_name}Create a file name for the current figure +% out of the base name and a running figure number: +% $\langle$\textit{name}$\rangle$.$\langle$\textit{number}$\rangle$.sk +% (E. g. pyramid.1.sk) +% \item \begin{enumerate} +% \item \label{proc:tex_file_found} If a file exists that is named +% like written in \ref{proc:gen_name} but with an additional +% \textit{.tex} at the end (e.g. pyramid.1.sk.tex) it is +% treated as a \SK{} processed result file. Thus, it is +% included as a replacement for the environments content. +% \item If such an item as in \ref{proc:tex_file_found} is not found +% a \SK{} file with the contents of the environment is saved +% to a file with the name generated in \ref{proc:gen_name}. +% \end{enumerate} +% \end{enumerate} +% In contrast to \MP{} \SK{} can't produce different output files out of +% one source file. This means every \SK{} figure has to be put into its +% own \SK{} file. As a consequence one has to process all generated \SK +% files with \SK and one can not have one generated file for the whole +% document. A possible way of managing the build (within a Makefile) of +% a document then could be: +% \begin{enumerate} +% \item Call |latex| on the document source +% \item Process all \SK{} files and stick to naming convention:\newline +% { |for i in `ls *.sk`; do sketch -o "$$i.tex" "$$i"; done| } +% \item Call either |latex| and |dvips| or |pdflatex| on the document +% source to actually see TikZ or PSTricks figures. +% \end{enumerate} +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Commands and Environments} +% \label{sec:commands} +% +% \DescribeEnv{esk} +% The |esk| environment contains the description of a single +% figure that will be placed at the location of the environment. +% The macro has two optional arguments. The first is the name of +% the figure and defaults to |\jobname|. It is used as the base +% name for file names. The second one consists of a comma separated +% list of names previously defined with |\eskdef|. Note that the +% names have to be put in parentheses (not brackets or braces). +% Those definitions will be prepended to the \SK-commands. +% \begin{quote} +% \begin{flushleft} +% |\begin{esk}[|\meta{name}|](|\meta{def 1}|,|\meta{def 2}|,...)|\\ +% \qquad\meta{\SK-commands}\\ +% |\end{esk}| +% \end{flushleft} +% \end{quote} +% +% \DescribeEnv{eskdef} +% The |eskdef| environment acts as a container for \SK-commands. +% In contrast to |esk| nothing is written to a file or drawn, but +% kept in a token list register to recall it later on. Thus, +% reoccurring patterns can be factored out and used as argument +% in an |esk| environment. This is useful, because these +% environments use the |verbatim| package and can therefore +% \emph{not} be used directly as an argument to other macros. +% \begin{quote} +% \begin{flushleft} +% |\begin{eskdef}{|\meta{name}|}|\\ +% \qquad\meta{\SK-commands}\\ +% |\end{eskdef}| +% \end{flushleft} +% \end{quote} +% +% \DescribeMacro{\eskprelude} +% Define a \SK{} prelude to be written to the top of every \SK{} +% file. The default is an empty prelude. Keep in mind that verbatim +% arguments are not allowed. +% +% \DescribeMacro{\eskaddtoprelude} +% Add to the \SK{} prelude. +% E. g.~|\eskaddtoprelude{def O (0,0,0)}| makes sure the variable O +% is available in all |esk| environments (and thus in every generated +% \SK{} file). Of cause, this could also be achieved with |Eskimo|. +% +% \DescribeMacro{\eskglobals} +% Define global \SK{} properties that get passed to the |global {...}| +% method of \SK. This defaults to |language tikz|. +% +% \DescribeMacro{\eskaddtoglobals} +% Add something to the global parameters of \SK. +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \subsection{Examples} +% \label{sec:examples} +% +% For a simple example, let's draw a pyramid in a coordinate +% system. Since our scene should be a composition of coordinate +% axes and the geometry, we prepare definitions for the single +% parts. In that way the parts will be reusable. First the +% coordinate system: +% \begin{macrocode} +%<*sample> +\begin{eskdef}{axes} + def three_axes { + % draw the axes + def ax (dx,0,0) + def ay (0,dy,0) + def az (0,0,dz) + line[arrows=<->,line width=.4pt](ax)(O)(ay) + line[arrows=->,line width=.4pt](O)(az) + % annotate axes + special |\path #1 node[left] {$z$} + #2 node[below] {$x$} + #3 node[above] {$y$};|(az)(ax)(ay) + } +\end{eskdef} +% \end{macrocode} +%\begin{eskdef}{axes} + def three_axes { + % draw the axes + def ax (dx,0,0) + def ay (0,dy,0) + def az (0,0,dz) + line[arrows=<->,line width=.4pt](ax)(O)(ay) + line[arrows=->,line width=.4pt](O)(az) + % annotate axes + special |\path #1 node[left] {$z$} + #2 node[below] {$x$} + #3 node[above] {$y$};|(az)(ax)(ay) + } +%\end{eskdef} +% Now the pyramid: +% \begin{macrocode} +\begin{eskdef}{pyramid} + def pyramid { + def p0 (0,2) + def p1 (1.5,0) + def N 4 + def seg_rot rotate(360 / N, [J]) + % draw the pyramid by rotating a line about the J axis + sweep[fill=red!20, fill opacity=0.5] { N<>, [[seg_rot]] } + line[cull=false,fill=blue!20,fill opacity=0.5](p0)(p1) + } +\end{eskdef} +% \end{macrocode} +%\begin{eskdef}{pyramid} + def pyramid { + def p0 (0,2) + def p1 (1.5,0) + def N 4 + def seg_rot rotate(360 / N, [J]) + % draw the pyramid by rotating a line about the J axis + sweep[fill=red!20, fill opacity=0.5] { N<>, [[seg_rot]] } + line[cull=false,fill=blue!20,fill opacity=0.5](p0)(p1) + } +%\end{eskdef} +% In the definitions some variable have been used that have +% not been declared so far (|O|, |dx|, |dy|, |dz|, |J|). They have +% been introduced to make the definitions more versatile. In +% order to draw the scene their declaration has to be prepended +% to our output: +% \begin{macrocode} +\eskaddtoprelude{def O (0,0,0)} +\eskaddtoprelude{def dx 2.3} +\eskaddtoprelude{def dy 2.5} +\eskaddtoprelude{def dz dx} +\eskaddtoprelude{def J [0,1,0]} +% \end{macrocode} +%\eskaddtoprelude{def O (0,0,0)} +%\eskaddtoprelude{def dx 2.3} +%\eskaddtoprelude{def dy 2.5} +%\eskaddtoprelude{def dz dx} +%\eskaddtoprelude{def J [0,1,0]} +% +% Now the previously created definitions can be used to do the +% actual drawing. First, the coordinate system on its own: +%\begin{center} +%\begin{esk}(axes) + def scene { + {three_axes} + } + put { view((10,4,2)) } {scene} +%\end{esk} +%\end{center} +% \begin{macrocode} +\begin{esk}(axes) + def scene { + {three_axes} + } + put { view((10,4,2)) } {scene} +\end{esk} +% \end{macrocode} +% Now the pyramid (note, the transparency effect will only be +% visible in a pdf): +%\begin{center} +%\begin{esk}(pyramid) + def scene { + {pyramid} + } + put { view((10,4,2)) } {scene} +%\end{esk} +%\end{center} +% \begin{macrocode} +\begin{esk}(pyramid) + def scene { + {pyramid} + } + put { view((10,4,2)) } {scene} +\end{esk} +% \end{macrocode} +% Finally both: +%\begin{center} +%\begin{esk}(axes,pyramid) + def scene { + {three_axes} + {pyramid} + } + put { view((10,4,2)) } {scene} +%\end{esk} +%\end{center} +% \begin{macrocode} +\begin{esk}(axes,pyramid) + def scene { + {pyramid} + {three_axes} + } + put { view((10,4,2)) } {scene} +\end{esk} +% +% \end{macrocode} +% With permission of Kjell Magne Fauske, the source code for this +% example scene has been taken from \cite{Fauske}. +% +% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% \begin{thebibliography}{99} +% \bibitem{Sketch} Eugene K.

We do this by parsing an RCS |Id| string and storing the +% result in the conventional \TeX{} control sequences.

Some other packages needed by +% \ESK{}, partly of a minimum version, get specified. +% \begin{macrocode} +\RequirePackage{verbatim} +\RequirePackage{kvsetkeys}[2007/09/29] +% \end{macrocode} +% The characters "\%", "\{" and "\}" are somewhat special to \TeX. More +% precisely are they used for comments and grouping respectively. \SK{} +% uses them as well, for the same purposes. To allow convenient code +% generation by using macros to produce the symbols, three macros get +% defined: +% \begin{macro}{\p@rcent} +% That macro is used for creating comments. The \% sign is locally +% defined as a common letter (category code 11) and create a global macro +% using it. The |@| in the name of the control sequence makes it only visible +% from inside the +% package\footnote{see http://de.wikibooks.org/wiki/LaTeX-Wörterbuch:\_\@}. +% \begin{macrocode} +{\catcode`\%=11\gdef\p@rcent{%}} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\lc@rly} +% \begin{macro}{\rc@rly} +% Curly braces are used for scope and group definitions in \SK. Just like +% with the |\p@rcent| macro, we need to make them a common letter. +% Unfortunately we need the curly braces to define a local scope for \TeX. +% To come around this the characters $>$ and $<$ are locally defined to +% be grouping characters (category code 1). To allow normal scope closing +% we finally make the curly braces grouping characters again. +% \begin{macrocode} +{\catcode`\>=1 \catcode`\<=2 + \catcode`\{=11 \catcode`\}=11 + \gdef\lc@rly>{< + \gdef\rc@rly>}< + \catcode`\{=1 \catcode`\}=2 +} +% \end{macrocode} +% \end{macro} +% \end{macro} +% +% \begin{macro}{\eskwrite} +% Define a macro to write the contents of its first argument to a file. +% If the Boolean toggle |@eskio| is set to true, the passed argument is +% written\footnote{see http://www.tug.org/utilities/plain/cseq.html\#write-rp} +% out to the file referenced in |@outesk|. Normally \TeX{} does the +% actual writing during a |\shipout| operation, but we force it to do it +% immediately\footnote{see http://www.tug.org/utilities/plain/cseq.html\#immediate-rp}. +% All directly following spaces on the input will be +% eaten\footnote{see http://en.wikibooks.org/wiki/TeX/ignorespaces}. +% \begin{macrocode} +\def\eskwrite#1{% + \if@eskio + \immediate\write\@outesk{#1}% + \fi + \ignorespaces} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\eskwritetoken} +% If a token list register should be put into a file, this macro should +% be used.

At this point no file is opened, but just an output channel +% defined\footnote{see \textit{A TEX primer for scientists} by Stanley +% A. Sawyer,Steven George Krantz on p. 283}. An example file open could now +% look like: |\openout\@outesk=TEXTFILE.TXT|. +% \begin{macrocode} +\newwrite\@outesk +% \end{macrocode} +% +% \begin{macro}{\eskfile} +% This environment encloses each \SK{} input file. The single optional +% argument gives the name of the file and defaults to |\jobname|. This will +% probably not be used explicitly when defining esk figures. It is invoked +% automatically with an appropriate name for a figure. The macro |\theeskfile| +% gets locally defined and stores the base name for a file. +% \begin{macrocode} +\newcommand{\eskfile}[1][\jobname]{% + \def\theeskfile{#1}% +% \end{macrocode} +% Open the Sketch file. If output is enabled, check if we're running under +% AMS-\LaTeX{} and if that is the case turn off I/O during the first pass over +% equation environments. This is done by looking for |\ifmeasuring@| of +% AMS-\LaTeX{} and, if found, replacing all |\if@eskio| checks with it. +% \begin{macrocode} + \if@eskio + \@ifundefined{ifmeasuring@}% + {}% + {\def\if@eskio{\ifmeasuring@\else}}% +% \end{macrocode} +% A a new output file is linked to our |\@outesk| file number.

Finally the argument +% is parsed as a comma separated list to call |\esk@def@processor| +% for each element found and the actual \SK{} code verbatim +% processing is started with |\esk@cmds|.

The +% macro has one parameter, the name of the definition. First a +% private and local name for the new block is defined. Then +% |\esk@def| checks if the name is already there and does the +% rest. +%% \iffalse TODO: Make it more robust by remembering old name +%% and setting it back afterwards (if any), so it can +%% be used in esk environments \fi +% \begin{macrocode} +\newcommand{\eskdef}[1]{% + %% Define a new name + \def\esk@@def@name{esk@def:#1}% + \esk@def} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\esk@def} +% The |\esk@def| macro relies on |\esk@@def@name| being defined +% previously. At the beginning it checks if that name is already +% registered by looking for a control sequence with the defined +% name. If so, an error message is produced. +% \begin{macrocode} +\def\esk@def{% + \expandafter\ifcsname\esk@@def@name\endcsname + \errmessage{"\esk@@def@name" is already defined!} + \fi +% \end{macrocode} +% If a new |eskdef| name is given a new token list register is +% created and named like the expansion of |\esk@@def@name|. It +% is not necessary to tell \TeX{} that the new register will be +% global, because \emph{new...} tokens act always globally. +% Unfortunately |\newtoks| is an |\outer| macro and we use the +% wrapper |\tok@newtoks| (see below) to call it. +% \begin{macrocode} + \expandafter\tok@newtoks\csname\esk@@def@name\endcsname +% \end{macrocode} +% Create or override a global definition |\esk@@def@reg| +% containing our new token register. Unfortunately, this works only +% with a global definition. Afterwards the verbatim reading of the +% environment is started with a different verbatim line processor as +% before. Finally the macro ends with removing the previously +% defined alias for the new token list register. +% \begin{macrocode} + \global\edef\esk@@def@reg{\csname\esk@@def@name\endcsname} + \esk@cmds{esk@def@verb@proc}} + \global\def\esk@@def@reg{} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\esk@def@verb@proc} +% The verbatim line processor for the |eskdef| environment first +% creates a local alias for the new token list register. This is +% done to make the code more readable. +% \begin{macrocode} +\def\esk@def@verb@proc#1{% + \expandafter\let\expandafter\token@reg\esk@@def@reg +% \end{macrocode} +% If the token list register is empty it is filled with the +% current verbatim line. +% \begin{macrocode} + \expandafter\ifx\expandafter*\the\token@reg* + \global\esk@@def@reg=\expandafter{\the#1} +% \end{macrocode} +% If not, the verbatim line is appended on a new line. +% \begin{macrocode} + \else + \global\esk@@def@reg=\expandafter{% + \the\expandafter\token@reg\expandafter^^J\the#1} + \fi} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\endeskdef} +% On ending an |eskdef| environment |\endeskdef| is expanded. Here, +% its only purpose is to invoke the macro ending the verbatim +% input environment. +% \begin{macrocode} +\def\endeskdef{ + \endesk@cmds} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\esk@@def} +% A macro which takes a file name as argument to globally define +% new macros |\esk@k:f:| and |\esk@k:c:| which expand +% to |\theeskfile| and |\theeskfig| respectively. +% \begin{macrocode} +\def\esk@@def#1{% + \global\e@namedef{esk@k:f:#1}{\theeskfile}% + \global\e@namedef{esk@k:c:#1}{\theeskfig}} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\e@namedef} +% A macro which defines a new macro with the name of the +% argument. This is done in use of |\expandafter| and +% |\csname|...|\endcsname|. The new macro expands to the +% following group, i.e. the new macros body. Due to the +% use of |\edef| this happens dynamically. +% \begin{macrocode} +\def\e@namedef#1{% + \expandafter\edef\csname #1\endcsname} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\esk@use} +% The |\esk@use| macro appends an \ESK{} \SK{} code definition +% defined by |\eskdef|, into the currently defined file. After +% creating an alias macro for the argument passed is is made +% sure that the definition actually exists. If not an error +% message is produced. If there is a token list register, named +% like passed as argument, a short describing comment is written. +% Further, the register is written as token to the file. The +% file writing is finished with a new line. +% \begin{macrocode} +\def\esk@use#1{% + \def\esk@@def@name{esk@def:#1}% + \expandafter\ifcsname\esk@@def@name\endcsname + \eskwrite{\p@rcent\p@rcent\space included definition: #1}% + \expandafter\eskwritetoken\expandafter{% + \expandafter\csname\esk@@def@name\endcsname} + \eskwrite{^^J} + \else + \errmessage{esk: "#1" is undefined!} + \fi +} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\tok@newtoks} +% Since |\newtoks| is an |\outer| macro, it is not allowed in definitions. +% Because we are in the need of creating token list registers on the +% fly, we define a wrapper.
