|
|
% version 1.4: Correction for use with \reversemargin
|
|
% Sep 29, 1994:
|
|
% version 1.5: Added the \iftopfloat, \ifbotfloat and \iffloatpage commands
|
|
% Oct 4, 1994:
|
|
% version 1.6: Reset single spacing in headers/footers for use with
|
|
% setspace.sty or doublespace.sty
|
|
% Oct 4, 1994:
|
|
% version 1.7: changed \let\@mkboth\markboth to
|
|
% \def\@mkboth{\protect\markboth} to make it more robust
|
|
% Dec 5, 1994:
|
|
% version 1.8: corrections for amsbook/amsart: define \@chapapp and (more
|
|
% importantly) use the \chapter/sectionmark definitions from ps@headings if
|
|
% they exist (which should be true for all standard classes).
|
|
% May 31, 1995:
|
|
% version 1.9: The proposed \renewcommand{\headrulewidth}{\iffloatpage...
|
|
% construction in the doc did not work properly with the fancyplain style.
|
|
% June 1, 1995:
|
|
% version 1.91: The definition of \@mkboth wasn't restored on subsequent
|
|
% \pagestyle{fancy}'s.
|
|
% June 1, 1995:
|
|
% version 1.92: The sequence \pagestyle{fancyplain} \pagestyle{plain}
|
|
% \pagestyle{fancy} would erroneously select the plain version.
|
|
% June 1, 1995:
|
|
% version 1.93: \fancypagestyle command added.
|
|
% Dec 11, 1995:
|
|
% version 1.94: suggested by Conrad Hughes <chughes@maths.tcd.ie>
|
|
% CJCH, Dec 11, 1995: added \footruleskip to allow control over footrule
|
|
% position (old hardcoded value of .3\normalbaselineskip is far too high
|
|
% when used with very small footer fonts).
|
|
% Jan 31, 1996:
|
|
% version 1.95: call \@normalsize in the reset code if that is defined,
|
|
% otherwise \normalsize.
|
|
% this is to solve a problem with ucthesis.cls, as this doesn't
|
|
% define \@currsize. Unfortunately for latex209 calling \normalsize doesn't
|
|
% work as this is optimized to do very little, so there \@normalsize should
|
|
% be called. Hopefully this code works for all versions of LaTeX known to
|
|
% mankind.
|
|
% April 25, 1996:
|
|
% version 1.96: initialize \headwidth to a magic (negative) value to catch
|
|
% most common cases that people change it before calling \pagestyle{fancy}.
|
|
% Note it can't be initialized when reading in this file, because
|
|
% \textwidth could be changed afterwards. This is quite probable.
|
|
% We also switch to \MakeUppercase rather than \uppercase and introduce a
|
|
% \nouppercase command for use in headers. and footers.
|
|
% May 3, 1996:
|
|
% version 1.97: Two changes:
|
|
% 1. Undo the change in version 1.8 (using the pagestyle{headings} defaults
|
|
% for the chapter and section marks. The current version of amsbook and
|
|
% amsart classes don't seem to need them anymore. Moreover the standard
|
|
% latex classes don't use \markboth if twoside isn't selected, and this is
|
|
% confusing as \leftmark doesn't work as expected.
|
|
% 2. include a call to \ps@empty in ps@@fancy. This is to solve a problem
|
|
% in the amsbook and amsart classes, that make global changes to \topskip,
|
|
% which are reset in \ps@empty. Hopefully this doesn't break other things.
|
|
% May 7, 1996:
|
|
% version 1.98:
|
|
% Added % after the line \def\nouppercase
|
|
% BY THE WAY, THIS IS THE LAST RELEASE OF VERSION 1.
