Not strictly necessary, but +% it is more LaTeX-like. +% 1999/02/05: \partmark defined (and in \setmarks, too). +% 1999/02/08: \ttl@row@i simplified. +% 1999/02/08: \ttl@savefn mechanism. +% 1999/02/10: Removed extra \leavevmode in display +% 1999/02/13: Now \titleline doesn't add the width. It's set. +% 1999/02/17: The part mark is catched, even if unused. +% 1999/02/17: old/newparttoc added. +% 1999/02/18: Changed many TeX assignments to the LaTeX +% counterpart. +% 1999/02/19: Introduced \ttl@startargs. +% +% History of v2.1.1 +% ~~~~~~~~~~~~~~~~~ +% 1999/08/04: Moved misplaced lines in \ttl@makeboth +% +% History of v2.2 (unreleased) +% ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +% 1999/11/03: We load titleps if pagestyles are required, but +% some old definitions are restored. +% 1999/11/06: Improved outermarks test in \ttl@sect@i. Formerly +% the section number could be printed if a page ended +% with an unnumebered section followed by a numbered one. +% 1999/11/06: \ttl@startargs now adds (and passes) automatically the +% section name. Involved macros modified accordingly. +% 1999/11/06: Replaced explicit part names by the parameter in +% \ttl@part@i. The same for chapter. +% 1999/11/21: \ttl@try's are not given explicitly, but built by +% \ttl@setkeys. Intruduced the \ttl@key@... and +% \ttl@extra@... commands. +% 1999/11/23: Minor problems with keys fixed. +% 1999/12/10: Added the nobottomtitles* option and \ttl@addstretch. +% 2000/01/07: First steps towards the calcwidth feature (basic code). +% 2000/01/08: (Continued.) \titleline* for rules of width \titlewidth. +% Option calcwidth implemented. +% 2000/01/12: Finished with changes in wrap.tss (no longer +% "experimental" :-) ) +% +% History of v2.3 +% ~~~~~~~~~~~~~~~ +% 2000/01/19: All keys are grouped in a single file tttkeys. Removed +% page.tsk and deleted the corresponding code in the sty. +% 2000/01/19: Classes begun. +% 2000/01/19: The level numbers are stored in \ttll@ macros, and not +% passed as arguments. +% 2000/01/21: Introduced the new mark scheme. It's mostly compatible +% with the old one, but a compatibility mode seems +% imposible (it was introduced in a preliminary test +% but eventually removed). +% 2000/01/23: loadonly package option. +% 2000/02/01: Classes finished. Many things had to be rewritten. +% 2000/02/02: Made partially compatible with hyperref (dvips). +% 2000/02/08: \ttl@savewrite moved from shapes to classes. But +% explicit page breaks expand it, too, to avoid wrong +% toc entries. +% 2000/02/18: A new box named \ttl@box stores the title in runin +% leftmargin etc shapes, to increase reliability. +% +% (2.3.1 -- 2.3.3: No changes on this file) +% +% History of v2.3.4 +% ~~~~~~~~~~~~~~~~~ +% 2000/05/12: nonindentfirst redefine \titlespacing instead of +% \@afterindent... so that they don't interfere with +% the first entry in tocs. +% 2000/05/17: The marks in \ttl@select are protected to prevent +% endless loop if the title is expanded, say, by +% \MakeUppercase. +% +% History of v2.3.5 +% ~~~~~~~~~~~~~~~~~ +% 2000/05/21: Restores missing test for secnumdepth in \ttl@mkchap, +% and instead of setting \ttl@toclevel in ttlps now is +% done in \secdef. Except inside the macros, \ttl@toclevel +% is false, so that an explicit \...mark works. +% 2000/06/04: \partmark defined with \providecommand +% 2000/06/14: A patch mechanism added, for small bug fixes. +% +% History of v2.4 +% ~~~~~~~~~~~~~~~~ +% 2001/01/18: Minor changes in code. Essentialy an incremental +% update. +% 2001/01/22: \titleformat has a new "easy" starred variant. +% +% History of v2.5 +% ~~~~~~~~~~~~~~~ +% 2002/01/02 New macros for \ttl@assign. Now * length allow +% non integer values. +% 2002/03/22 Added \ttl@calc and \ttl@calcneg to make titlesec +% calc-savvy. +% - Merged bug fixes of .new into this file. +% - Bugs in frame fixed -- gap in lines, misplaced +% label, wrong margins (sometimes), +% - \leftskip, \rightskip and \linewidth (re)set in +% margin shapes. +% - Removed obsolete flush... options. +% - indentafter and noindentafter, new names for +% indentfirst and nonindentfirst. +% - A new level (\titleclass) without its "location" +% now raises a meaningful error. +% - Bug in top-level \titleclass fixed. +% 2002/03/23 Tests for undefined and unformatted sectioning levels, +% and horizontal material in <format>. +% - Missing \if@openright inside \if@twoside in +% page class added. +% - Removed extra (but inoffensive) \expandafter +% in \ttl@class@iii. +% 2002/03/27 Added \titlewidthfirst and ...last +% - «Not definable» gives a more meaningful message in +% the context of the package. +% +% History of v.2.6 +% ~~~~~~~~~~~~~~~~ +% 2004/08/30 Corrected typo in margin \hsiz -> \hsize. +% 2004/10/17 Added a couple of missing \noexpand's in drop. +% 2004/12/01 Removed the error about the mode in block because this +% style is general purpose. +% 2005/01/16 Missing braces around #2 in the last else part of +% \ttl@headinline added +% - Replaced explicit \makeatother's by a saved value as +% the macros can be used in a class/package file. +% 2005/01/18 newlinetospace mechanism +% 2005/01/18 // does not break pages; option pageatnewline to +% restore the LaTeX behaviour. +% 2005/01/19 \...break in top shape. +% - Renumbered several scratch registers to follow the +% TeXbook (p. 346), with \ttl@box in a few cases. In +% wrap \titlewidthfirst and \titlewidthlast made global. +% - Float heads and foots have now a further argument for +% additional stuff (eg, to remove rules). Option is now +% psfloats while floatps enters in compatibility mode. +% - \ttl@savetitle in all classes. Option toctitles. +% 2005/01/21 Changed pageatnewline to make it compatible with +% titletoc, with \ttl@changecentercr. +% 2005/01/22 \...tolist in top class. +% +% Notes +% ~~~~~ +% +% The following tags are used: +% ttl@ : the generic tag used through the style +% ttlh@ : a shape definition +% ttlf@ : a macro containing the title format +% ttls@ : id. the title space +% ttlp@ : page key related macros +% ttll@ : level number +% +% The ttlf@ and ttls@ contains data in the form {..}{..}. +% Perhaps in future releases they should be converted +% to a prop-like list, similar to that proposed by the +% latex team. +% +% Admittedly, the current implementation seems too +% complicated, but that's necessary in order to provide +% certain compatibility with the sections as defined by the +% used class. Other packages opt for providing the sections +% as defined by standard classes ignoring the class; for +% instance sectsty which does a simple task in a simple and +% nice way.
