| 4 : | % ShadeThm.sty | ||
| 5 : | % Shaded theorem environments in LaTeX, with \newshadetheorem in addition to | ||
| 6 : | % \newtheorem. | ||
| 7 : | % | ||
| 8 : | % USAGE | ||
| 9 : | % Used as a LaTeX2e style, with \usepackage{shadethm}, it allows declarations | ||
| 10 : | % of the form \newshadetheorem{theorem}{Theorem}, so that | ||
| 11 : | % \begin{theorem} $e=mc^2$ \end{theorem} | ||
| 12 : | % will produce the usual theorem, only placed in a shaded box. | ||
| 13 : | % Options. Two come in this file: | ||
| 14 : | % bodymargin (default) The body of the shaded text lines up with the | ||
| 15 : | % margins. Just as though you called newtheorem, then colored later. | ||
| 16 : | % Shading falls outside the margin. | ||
| 17 : | % shademargin The shading lines up with the margins, so the body of | ||
| 18 : | % shaded text comes out a little thinner. | ||
| 19 : | % If you call it with an option not on that list then it will look for a | ||
| 20 : | % file <OptionName>.sth and take the parameters from there. See the included | ||
| 21 : | % files shadein.sth and colored.sth, the first of which gives theorems that are | ||
| 22 : | % (like LaTeX quotations) indented left and right and the second of which | ||
| 23 : | % gives color shading. | ||
| 24 : | % | ||
| 25 : | % REMARKS | ||
| 26 : | % (1) You can of course have non-shaded environments, also. The \newtheorem | ||
| 27 : | % command still works. | ||
| 28 : | % (2) Numbering within: An prior version of this style required that you | ||
| 29 : | % number within like this: | ||
| 30 : | % \newshadetheorem{thm}{Theorem} | ||
| 31 : | % \newshadetheorem{note}[shadethm]{Note} % No longer needed! | ||
| 32 : | % but this one drops that requirement. If you didn't use the old version, | ||
| 33 : | % forget about it. | ||
| 34 : | % (3) Uses the graphics package. Look for it in the CTAN TeX-archive nearest | ||
| 35 : | % you, for instance at tug.ctan.org. | ||
| 36 : | % (4) Works with amsthm.sty. | ||
| 37 : | % (5) Notice that if you say \newshadetheorem{theorem}{Theorem} and then | ||
| 38 : | % \newtheorem{theorem}{Theorem} then you will get an error message since | ||
| 39 : | % the first allows you to say \begin{theorem} ..., as does the second. | ||
| 40 : | % | ||
| 41 : | % INSTALLATION | ||
| 42 : | % Put this where your TeX looks for .sty files. | ||
| 43 : | % There are some parameters you could set the default for (try them as is, | ||
| 44 : | % first). | ||
| 45 : | % (i) shadethmcolor The shading color of the background. See the | ||
| 46 : | % documentation for the color package, but with a `gray' model, I find .97 | ||
| 47 : | % looks good out of my printer, while a darker shade like .92 is needed | ||
| 48 : | % to make it copy well. (Black is 0, white is 1.) | ||
| 49 : | % (i*) shaderulecolor The shading color of the border of the shaded box. | ||
| 50 : | % See (i). If \shadeboxrule is set to 0pt then this won't print anyway. | ||
| 51 : | % (i**) shadeboxrule The width of the border around the shading. Set it to | ||
| 52 : | % 0pt (not just 0) to make it disappear. | ||
| 53 : | % (i***) shadeboxsep The length by which the shade box surrounds the text. | ||
| 54 : | % (ii) shadesetinsideminipage The theorems are set inside a minipage to | ||
| 55 : | % get line breaks, but some things, like paragraph indents, are messed | ||
| 56 : | % with there, so I have a hook to reset them. Probably you can just | ||
| 57 : | % leave this alone. | ||
| 58 : | % (iii) The default option. Change the \ExecuteOptions{...} right before | ||
| 59 : | % the \ProcessOptions. | ||
| 60 : | % Comment: | ||
| 61 : | % If you get an error about `undefined color model' then you need to create | ||
| 62 : | % the file color.cfg in the same place as color.sty, and put in it the line | ||
| 63 : | % \ExecuteOptions{dvips} (or whatever is the name of your driver). See the | ||
| 64 : | % documentation for the graphics package. I needed this in the distant past | ||
| 65 : | % under NTeX. | ||
| 66 : | % | ||
| 67 : | % BUGS | ||
| 68 : | % (1) Page breaks are a problem since it sets the theorem before it is shaded. | ||
| 69 : | % The theorem is put into a minipage in order to have the right line breaks | ||
| 70 : | % put in, but then can't be broken across pages. I'd be interested in any | ||
| 71 : | % fixes for this. DA? | ||

| 80 : | % HISTORY | ||
| 81 : | % 99XI23 jh Redid the parsing to stick to \newcommand-style calls. Needed | ||
| 82 : | % to put in some oppresive \expandafter strings. | ||
| 83 : | % 99VII09 jh tex@joshua.smcvt.edu Fixed the number within situation. LPPL | ||
| 84 : | % added. | ||
| 85 : | % 97I07 jh Changed the interior of the \DeclareOptions to \AtBeginDocument | ||
| 86 : | % for cases where the \textwidth is changed. | ||
| 87 : | % 95VI19 jh Adapted for LaTeX2e. Now uses the graphics package, and all | ||
| 88 : | % the neat 2e package stuff. Still haven't rewritten the parsing code to | ||
| 89 : | % use the new optional arguments to \newcommand, though. Ah well. | ||
| 90 : | % 94VII11 jim hefferon hefferon@smcvax.smcvt.edu. First written (after lots | ||
| 91 : | % of sporadic tries, over months; I couldn't get any of the extant shading | ||
| 92 : | % macros to work with theorems) from a hint in TvZ's Fancybox writeup. | ||
| 93 : | % It's all so easy once you know how. | ||

| 153 : | % MAIN CODE | ||
| 154 : | % see LaTeXbook (second edition) pp 108 and 132 | ||
| 155 : | % (1) make a box \saveshadebox that will hold the text that is to be | ||
| 156 : | % typeset in the theorem. | ||
| 157 : | % (2) Read that material in with the lrbox environment. The material | ||
| 158 : | % is set in a minipage so the margins are controllable. | ||
| 159 : | % (3) Use that box, inside of an fcolorbox. | ||
| 160 : | % Notes | ||
| 161 : | % * lrbox is used instead of savebox because this is an environment. | ||
| 162 : | % * The fcolorbox is inside a trivlist because that makes the vertical | ||
| 163 : | % spacing come out right. I don't know how else to do it. | ||
| 164 : | % * The fcolorbox is left shifted by some length (which may be negative) and | ||
| 165 : | % then aftward, a right shift is put in. | ||
| 166 : | \newsavebox{\shadesavebox} % no `@'; users can redefine shadebox if they want | ||
| 167 : | \newenvironment{shadebox}% % shadow boxes or something. | ||
| 168 : | {\begin{lrbox}{\shadesavebox}\begin{minipage}{\shadedtextwidth}% | ||
| 169 : | \shadesetinsideminipage}% | ||
| 170 : | {\end{minipage}\end{lrbox}% | ||
| 171 : | \begin{trivlist}\item[]% In a trivlist because theorems are in trivlists. | ||
| 172 : | \setlength{\fboxsep}{\shadeboxsep}% | ||
| 173 : | \setlength{\fboxrule}{\shadeboxrule}% | ||

| 177 : | %PARSING CODE | ||
| 178 : | % The definition of \newshadetheorem is modelled on the one for \newtheorem | ||
| 179 : | % in latex.tex. | ||
| 180 : | % The invocation possibilities are: | ||
| 181 : | % \newshadetheorem{NAME}{TEXT}[COUNTER] | ||
| 182 : | % e.g., \newshadetheorem{theorem}{Theorem}[section] meaning to allow | ||
| 183 : | % one to say \begin{theorem} $e=mc^2$ \end{theorem} to produce | ||
| 184 : | % Theorem 1.1.1 e=mc2 | ||
| 185 : | % shaded and numbered by section. | ||
| 186 : | % \newshadetheorem{NAME}[OLDNAME]{TEXT} | ||
| 187 : | % e.g., \newshadetheorem{remark}[theorem]{Remark} meaning to allow | ||
| 188 : | % one to say \begin{remark} Obvious. \end{remark} to produce | ||
| 189 : | % Remark 1.1.2 Obvious. | ||
| 190 : | % shaded and numbered with the same counter used for theorems. | ||
| 191 : | % \newcommand parsing | ||
| 192 : | % In LaTeX2e, to call a macro with an optional argument, let the | ||
| 193 : | % optional's default value be given in a second set of []'s: | ||
| 194 : | % \newcommand{\mymac}[2][hello]{#2, ``#1''} will have | ||
| 195 : | % \mymac{I say} |---> I say ``hello'' | ||
| 196 : | % \mymac[goodbye]{You say} |---> You say ``goodbye'' | ||
| 197 : | % I want to use this to parse LaTeX's | ||
| 198 : | % \newtheorem{--env_name--}{--caption--}[--within--] | ||
| 199 : | % or \newtheorem{--env_name--}[--numbered_like--]{--caption--} | ||
| 200 : | % So | ||
| 201 : | % (1) \newshadetheorem{arg1} | ||
| 202 : | % arg1: the environment name (e.g. definition) | ||
| 203 : | % It ends by calling a macro \sth@getcaption with one mandatory argument and | ||
| 204 : | % one optional argument. | ||
| 205 : | % (2) \sth@getcaption[oparg1]{arg1} | ||
| 206 : | % arg1: the caption name (e.g. Definition) | ||
| 207 : | % oparg1: the numbered_like (e.g., theorem) | ||
| 208 : | % It ends by calling a macro \sth@getwithin of no mandatory arguments but | ||
| 209 : | % one optional argument. | ||
| 210 : | % (3) \sth@getwithin[oparg1] | ||
| 211 : | % oparg1: the numbered within (e.g. subsection) | ||
| 212 : | % This routine finishes the processing. Depending on the four possibilities | ||
| 213 : | % of whether there is a numbered_like or not, and whether there is a | ||
| 214 : | % within or not, \newtheorem is called as is appropriate. | ||
| 215 : | % If there is no numbered_like, then the counter has to be set. That is, | ||
| 216 : | % a user expects to say \newtheorem{corollary}[theorem]{Corollary} and get | ||
| 217 : | % a corollary environment that is numbered in the same sequence as the | ||
| 218 : | % theorem environment, e.g., uses the theorem counter c@theorem. But in | ||
| 219 : | % runnning the \newshadetheorem we have called a \newtheorem{shadetheorem}... | ||
| 220 : | % and so the counter actually created is c@shadetheorem. We need the three | ||
| 221 : | % c@theorem, p@theorem and \thetheorem. | ||
| 222 : | % **** Remark on the \expandafter madness **** | ||
| 223 : | % Probably I am going about this all wrong ... | ||
| 224 : | % The construct | ||
| 225 : | % \newtheorem{\sth@envname}{\sth@caption} | ||
| 226 : | % doesn't do the job here because the \sth@envname and sth@caption aren't | ||
| 227 : | % resolved until they are called in the document: | ||
| 228 : | % after \newshadetheorem{theorem}{Theorem} | ||
| 229 : | % \newshadetheorem{corollary}{Corollary} | ||
| 230 : | % and later in the document | ||
| 231 : | % \begin{theorem} .. \end{theorem} | ||
| 232 : | % we get ``Corollary'' because that's what \sth@envname is at that moment. | ||
| 233 : | % Aarrg! | ||
| 234 : | % Instead, it has to be expanded when \newshadetheorem is called. This is | ||
| 235 : | % hard, IMHO. \expandafter<tok1><\tok2> puts <tok1> on a stack and expands | ||
| 236 : | % <tok2>. If <tok2> is another \expandafter then we have | ||
| 237 : | % \expandafter<tok1>\expandafter<tok3><tok4> which resolves to | ||
| 238 : | % <tok1><tok3><expansion of tok4>. If <tok1> is another \expandafter then | ||
| 239 : | % there is another round of expansion. | ||
| 240 : | % * To have \newshadetheorem{thm}{Thm} expand, we do this (where \ea is an | ||
| 241 : | % abbreviation for \expandafter): | ||
| 242 : | % \ea\ea\ea\newtheorem\ea\ea\ea{\ea\sth@shadeenvname\ea}\ea{\sth@caption} | ||
| 243 : | % ... which resolves to ... | ||
| 244 : | % \ea \newtheorem \ea { \sth@shadeenvname } {Thm } | ||
| 245 : | % ... which in turn resolves to ... | ||
| 246 : | % \newtheorem { thm } {Thm } | ||
| 247 : | % ... which is what I want. | ||
| 248 : | % * To have a three-argument case come out right, we need seven \ea's. | ||
| 249 : | % Consider the one that we want to come out as \newtheorem{thm}{Thm}[section]. | ||
| 250 : | % \ea\ea\ea\ea\ea\ea\ea\newtheorem\ea\ea\ea\ea\ea\ea\ea{ | ||
