|
|
%%% This includes GDG's modification to Erica Harris'
|
|
%%% setspace.sty. The main aspects of this
|
|
%%% modification deal with the definitions of
|
|
%%% \singlespacing \onehalfspacing, and
|
|
%%% \doublespacing, (these are near the beginning of
|
|
%%% the file). Primarily, these deal with adding
|
|
%%% fontsize changes to guarantee that the new
|
|
%%% baseline is properly defined and placed into
|
|
%%% action. The extra \vskip in the definition of
|
|
%%% \singlespacing seems to make for a cleaner
|
|
%%% transition from multiple spacing back to single
|
|
%%% spacing. These did not appear warrranted for
|
|
%%% other size changes.
|
|
%%%
|
|
%%% Modified by GDG on November 1, 1992, to allow
|
|
%%% for use of New Font Selection Scheme.
|
|
%%%
|
|
%%% Modified by GDG on June 4, 1993, to correct
|
|
%%% for spacing tokens in definition of \@setsize
|
|
%%% Thanks to Kaja P. Christiansen <kaja@daimi.aau.dk>
|
|
%%% for the fix!!
|
|
%%%
|
|
%%% Modified by GDG on May 24, 1994, to change toggle
|
|
%%% definition from \selectfont to \@newbaseline.
|
|
%%%
|
|
%%% Modified by GDG on May 25, 1994, to add
|
|

%%% This should help with some of the awkward math

|
%%%
|
|
%%% Rowland J.~Bartlett

%%% <michal@ellpspace.math.ualberta.ca>
|
|
%%% on Fri 27 Sep 96.
|
|
%%%
|
|
%%% GT: Sat 28 Sep 1996: Added call to

|
%%% \setspace@size in \setstretch, as suggested
|
|
%%% by David Hull <hull@cs.uiuc.edu>
|
|
%%% on Wed 24 July 1996.
|
|
%%%
|
|
%%% GT: Sat 28 Sep 1996: Pared \setspace@size
|
|
%%% mercilessly down to \@currsize, following
|
|
%%% advice given on Fri 27 Sep 1996 by Michal
|
|
%%% Jaegermann <michal@ellpspace.math.ualberta.ca>.
|
|
%%% Retained this macro for flexibility.
|
|
%%%
|
|
%%% Code rearranged by GT, Sat 28 Sep 1996, to give
|
|
%%% greater prominence to \setstretch.
|
|
%%%
|
|
%%% Also, GT changed (Sat 28 Sep 1996) many
|
|
%%% occurrences of \def to \newcommand,
|
|
%%% \renewcommand, or \newenvironment,
|
|
%%% as seemed appropriate.
|
|
%%%
|
|
%%% GT, Tue 10 Dec 1996: Following a suggestion
|
|
%%% by Ted Stern, the `single' spacing is now
|
|
%%% settable by the user. This is for slightly
|
|
%%% large fonts such as Lucida Bright.
|
|
%%%
|
|
%%% GT, Wed 11 Dec 1996: For simplicity and
|
|
%%% maintainability, call \onehalfspacing in
|
|
%%% the onehalfspace environment, and
|
|
%%% \doublespacing in the doublespace
|
|
%%% environment.
|
|
%%%
|
|
%%% GT, Wed 11 Dec 1996: Also deleted
|
|
%%% \setspace@size from \setstretch,
|
|
%%% as \@currsize suffices.
|
|
%%%
|
|
%%% Modified by Brett Presnell (BP)
|
|
%%% <presnell@maths.anu.edu.au> on 21 Mar 1998
|
|
%%% to add nodisplayskipstretch option, which
|
|
%%% turns off the stretching of the space
|
|
%%% before and after displays, which is often
|
|
%%% excessive, particularly with doublespaced
|
|
%%% documents. Also added the
|
|
%%% setdisplayskipstretch command, which allows
|
|
%%% the user to choose by how much to stretch
|
|
%%% the space before and after displays
|
|
%%% independently from the setting of
|
|
%%% baselinestretch. This works regardless of
|
|
%%% whether the nodisplayskipstretch option is
|
|
%%% in effect.
|
|
%%%
|
|
%%% GT, Wed 15 Apr 1998: Added the singlespace*
|
|
%%% environment requested by
|
|
%%% Mark Olesen <olesen@weber.me.queensu.ca>
|
|
%%% on Sat 24 May 1997 and Wed 18 June 1997.
|
|
%%% This is reported to give improved vertical
|
|
%%% spacing around itemize and quote environments.
|
|
%%%
|
|
%%% GT, Wed 15 Apr 1998: David Hull pointed out on
|
|
%%% Fri 12 Dec 1997 that the \belowdisplayskip line
|

%%% in the \everydisplay was mistyped. Now fixed.
|
|
%%%
|
|
%%% GT, Thu 26 Nov 1998: Finally got round to

%%% GT, Tue 27 July 1999: On Saturday 24 July

%%% 1999, Alexander L. Wolf <alw@cs.colrado.edu>

%%%
|
|
%%% GT, Fri 3 March 2000: Today Stefano

|
|
%%% the need to extend the commands and macros
|
|
%%% to point sizes other than 10, 11 and 12.
|
|
%%% Since there's no general formula for the

%%% line stretch values in terms of point size,
|
|
%%% and they vary only slightly between 10, 11
|
|
%%% and 12 pt, and furthermore the values were

%% AUTHOR: Erica M. S. Harris
|
|
%% DATE: April 1990
|
|
%% MOD: March 1991
|
|
%%%
|
|
%%% Update to LaTeX (2e) : 6 Feb 1996.
|
|
%%% Description: LaTeX Document Package "setspace"
|
|
%%%
|
|
%%% Usage:
|
|
%%% \documentclass[...]{...}
|
|
%%% \usepackage{setspace}
|
|
%%%
|
|
%% Based on the doublespace option created by Stephen Page.
|
|
%%
|
|
%% This style option provides commands and environments for doing
|
|
%% double and one-and-a-half spacing based on pt size.
|
|
%%
|
|
%% Single spacing is the default.
|
|
%%
|
|
%% Three commands, \singlespacing, \onehalfspacing, and
|
|
%% \doublespacing, are for use in the preamble to set the overall
|
|
%% spacing for the document. If a different spacing is required then
|
|
%% the \setstretch{baselinestretch} command can be used in the
|
|
%% preamble to set the baselinestretch appropriately. The default
|
|
%% spacing with this style option is single spacing.
|
|
%%
|
|
%% Three environments, singlespace, onehalfspace, and doublespace,
|
|
%% allow the spacing to be changed within the document. Both the
|
|
%% onehalfspace and doublespace environments are intended to increase
|
|
%% the spacing, so the onehalfspace environment should not be used in
|
|
%% a double spaced document. If an increased spacing different from
|
|
%% one-and-a-half or double spacing is required then the spacing
|
|
%% environment can be used. The spacing environment takes one
|
|
%% argument which is the larger baselinestretch to use,
|
|
%% e.g., \begin{spacing}{2.5}.
|
|
%%
|
|
%% \footins is adjusted the same as \parskip - appears to work. Lose
|
|
%% stretch parts but don't consider that to be crucial
|
|
%%
|
|
%% Removed code for altering spacing before and after displayed
|
|
%% equations - just looked too much.
|
|
%%
|
|
%% MODS:
|
|
%% Redefinition of \spacing and \endspacing for consistency with
|
|
%% TeX 3.x inserted by George Greenwade. Modification provided by
|
|
%% Philip Ross (ROSS@UK.AC.ABDN.BIOMED) and John Byrne via INFO-TeX.
|
|
%%
|
|
%% PLEASE REPORT ANY BUGS
|
|
%%
|
|
%% Old Documentation follows:
|
|
%% 1. A new environment "singlespace" is provided, within which single
|
|
%% spacing will apply.
|
|
%% JFL - changed so that it works in regular text and so that
|
|
%% vertical space before and after is correctly computed
|
|
%% 2. Double spacing is turned off within footnotes and floats (figures
|
|
%% and tables).
|
|
%% 3. Proper double spacing happens below tabular environments and in
|
|
%% other places where LaTeX uses a strut.
|
|
%% 4. Slightly more space is inserted before footnotes.
|
|
%% 5. JFL - fixes spacing before and after displayed math

|
|
%%
|
|
%% POSSIBLE BUGS:
|
|
%% . Increasing struts may possibly cause some other obscure part of
|
|
%% formatting to fall over.
|
|
%% . \begin{singlespace}\begin{quote} produces the wrong spacing before
|
|
%% the quote (extra glue is inserted).

% GT: EMSH chose to omit display math part that follows.
|
|
% She wrote (see above) that the "altered spacing before and after displayed
|
|
% equations ... just looked too much".
|

%
|
|
% Fix up spacing before and after displayed math
|
|
% (arraystretch seems to do a fine job for inside LaTeX displayed math,
|
|
% since array and eqnarray seem to be affected as expected).
|
|
% Changing \baselinestretch and doing a font change also works if done here,
|
|
% but then you have to change @setsize to remove the call to @nomath)

% \baselinestretch by \displayskipstretch in displays, as follows.
