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.

This change was successively %%% advised by: %%% %%% Rowland J.~Bartlett %%% %%% on Tue 6 Aug 96, %%% %%% Ted Stern %%% %%% on Wed 7 Aug 96, %%% %%% Michal Jaegermann %%% %%% on Fri 27 Sep 96. %%% %%% GT: Sat 28 Sep 1996: Added call to %%% \setspace@size in \setstretch, as suggested %%% by David Hull %%% 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 . %%% 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 %%% 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 %%% 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.

Wolf %%% informed me that the \doublespace and %%% \onehalfspace _macros_ are still at fault. %%% %%% GT, Fri 3 March 2000: Today Stefano %%% Lacaprara of Italy brought my attention to %%% 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 %%% presumably optimised specifically for the %%% Computer Modern fonts, i've chosen to use %%% the 10 pt values as the generic defaults. %%% %%% The checksum field above contains a CRC-16 %%% checksum as the first value, followed by the %%% equivalent of the standard UNIX wc (word %%% count) utility output of lines, words, and %%% characters. This is produced by Robert %%% Solovay's checksum utility." %%% } %%% ====================================================================== %% FILE: setspace.sty in SYS2.TEX.PUB.ISULATEX.STYLES %% 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 %% %% %% mods: Jean-Francois Lamy %% lamy@ai.toronto.edu %% lamy@utai.uucp %% %% 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). %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \NeedsTeXFormat {LaTeX2e}[1994/12/01] \def \filename {setspace.sty} \def \filedate {2000/03/03} \def \fileversion {6.6} \ProvidesPackage {setspace}[\filedate\space\fileversion\space Contributed and Supported LaTeX2e package] \typeout {Package: `setspace' \fileversion\space } % BP: add nodisplayskipstretch option and \setdisplayskipstretch command. \newcommand{\displayskipstretch}{\baselinestretch} \newcommand{\setdisplayskipstretch}[1]{\renewcommand{\displayskipstretch}{#1}} \DeclareOption{nodisplayskipstretch}{\setdisplayskipstretch{1.0}} \ProcessOptions % GT: Sat 28 Sep 1996: Widely using \newcommand, \renewcommand, and % \newenvironment, instead of \def. % ** Line space commands. \newcommand{\setstretch}[1]{% \def\baselinestretch{#1}% \@currsize } % GT: Sat 28 Sep 1996: spacing commands and environments modified to % use \setstretch instead of \baselinestretch. % % GT: Sat 28 Sep 1996: No, I don't know understand the line spacing % algorithms!
