Email: piet@cs.ruu.nl 6% Sep 16, 1994 7% version 1.4: Correction for use with \reversemargin 8% Sep 29, 1994: 9% version 1.5: Added the \iftopfloat, \ifbotfloat and \iffloatpage commands 10% Oct 4, 1994: 11% version 1.6: Reset single spacing in headers/footers for use with 12% setspace.sty or doublespace.sty 13% Oct 4, 1994: 14% version 1.7: changed \let\@mkboth\markboth to 15% \def\@mkboth{\protect\markboth} to make it more robust 16% Dec 5, 1994: 17% version 1.8: corrections for amsbook/amsart: define \@chapapp and (more 18% importantly) use the \chapter/sectionmark definitions from ps@headings if 19% they exist (which should be true for all standard classes). 20% May 31, 1995: 21% version 1.9: The proposed \renewcommand{\headrulewidth}{\iffloatpage... 22% construction in the doc did not work properly with the fancyplain style. 23% June 1, 1995: 24% version 1.91: The definition of \@mkboth wasn't restored on subsequent 25% \pagestyle{fancy}'s. 26% June 1, 1995: 27% version 1.92: The sequence \pagestyle{fancyplain} \pagestyle{plain} 28% \pagestyle{fancy} would erroneously select the plain version. 29% June 1, 1995: 30% version 1.93: \fancypagestyle command added. 31% Dec 11, 1995: 32% version 1.94: suggested by Conrad Hughes <chughes@maths.tcd.ie> 33% CJCH, Dec 11, 1995: added \footruleskip to allow control over footrule 34% position (old hardcoded value of .3\normalbaselineskip is far too high 35% when used with very small footer fonts). 36% Jan 31, 1996: 37% version 1.95: call \@normalsize in the reset code if that is defined, 38% otherwise \normalsize. 39% this is to solve a problem with ucthesis.cls, as this doesn't 40% define \@currsize. Unfortunately for latex209 calling \normalsize doesn't 41% work as this is optimized to do very little, so there \@normalsize should 42% be called. Hopefully this code works for all versions of LaTeX known to 43% mankind. 44% April 25, 1996: 45% version 1.96: initialize \headwidth to a magic (negative) value to catch 46% most common cases that people change it before calling \pagestyle{fancy}. 47% Note it can't be initialized when reading in this file, because 48% \textwidth could be changed afterwards. This is quite probable. 49% We also switch to \MakeUppercase rather than \uppercase and introduce a 50% \nouppercase command for use in headers. and footers. 51% May 3, 1996: 52% version 1.97: Two changes: 53% 1. Undo the change in version 1.8 (using the pagestyle{headings} defaults 54% for the chapter and section marks. The current version of amsbook and 55% amsart classes don't seem to need them anymore. Moreover the standard 56% latex classes don't use \markboth if twoside isn't selected, and this is 57% confusing as \leftmark doesn't work as expected. 58% 2. include a call to \ps@empty in ps@@fancy. This is to solve a problem 59% in the amsbook and amsart classes, that make global changes to \topskip, 60% which are reset in \ps@empty. Hopefully this doesn't break other things. 61% May 7, 1996: 62% version 1.98: 63% Added % after the line \def\nouppercase 64% BY THE WAY, THIS IS THE LAST RELEASE OF VERSION 1. 65 66\let\fancy@def\gdef 67\def\lhead{\@ifnextchar[{\@xlhead}{\@ylhead}} 68\def\@xlhead[#1]#2{\fancy@def\@elhead{#1}\fancy@def\@olhead{#2}} 69\def\@ylhead#1{\fancy@def\@elhead{#1}\fancy@def\@olhead{#1}} 70 71\def\chead{\@ifnextchar[{\@xchead}{\@ychead}} 72\def\@xchead[#1]#2{\fancy@def\@echead{#1}\fancy@def\@ochead{#2}} 73\def\@ychead#1{\fancy@def\@echead{#1}\fancy@def\@ochead{#1}} 74 75\def\rhead{\@ifnextchar[{\@xrhead}{\@yrhead}} 76\def\@xrhead[#1]#2{\fancy@def\@erhead{#1}\fancy@def\@orhead{#2}} 77\def\@yrhead#1{\fancy@def\@erhead{#1}\fancy@def\@orhead{#1}} 78 79\def\lfoot{\@ifnextchar[{\@xlfoot}{\@ylfoot}} 80\def\@xlfoot[#1]#2{\fancy@def\@elfoot{#1}\fancy@def\@olfoot{#2}} 81\def\@ylfoot#1{\fancy@def\@elfoot{#1}\fancy@def\@olfoot{#1}} 82 83\def\cfoot{\@ifnextchar[{\@xcfoot}{\@ycfoot}} 84\def\@xcfoot[#1]#2{\fancy@def\@ecfoot{#1}\fancy@def\@ocfoot{#2}} 85\def\@ycfoot#1{\fancy@def\@ecfoot{#1}\fancy@def\@ocfoot{#1}} 86 87\def\rfoot{\@ifnextchar[{\@xrfoot}{\@yrfoot}} 88\def\@xrfoot[#1]#2{\fancy@def\@erfoot{#1}\fancy@def\@orfoot{#2}} 89\def\@yrfoot#1{\fancy@def\@erfoot{#1}\fancy@def\@orfoot{#1}} 90 91\newdimen\headrulewidth 92\newdimen\footrulewidth 93\newdimen\plainheadrulewidth 94\newdimen\plainfootrulewidth 95\newdimen\headwidth 96\newdimen\footruleskip 97\newif\if@fancyplain \@fancyplainfalse 98\def\fancyplain#1#2{\if@fancyplain#1\else#2\fi} 99\headwidth=-123456789sp %magic constant 100 101% Command to reset various things in the headers: 102% a.o. single spacing (taken from setspace.sty) 103% and the catcode of ^^M (so that epsf files in the header work if a 104% verbatim crosses a page boundary) 105% It also defines a \nouppercase command that disables \uppercase and 106% \Makeuppercase.
