%% ******************************************************************
%%
%% Non-package resources
%%
%% There is one resource not available in packaged form, the module that lets LaTeX create random values. This is in `random.tex`, which on the author's system is hiding in a directory `texmf/tex/generic/genmisc/`, in the `texmf-dist` tree, and indexed by an `ls-R` database, so it should therefore be findable by any TeX system.
\input{random.tex}
%%
%% ******************************************************************
%%
%% The code
%%
%% This is beta software: the code is messy and covered in tracing output.
%%
%% Font selection
%%
%% This is set in the `\input` file `pickfont.tex`, which is created by the preparatory data script `prepdata.sh`. It is the number of working text fonts found on the system.
\newcounter{SIL@maxfont}
%%
%% This is set to a random number between one and `\SIL@maxfont`, and used as the name of the file containing the font name.
\newcounter{SIL@fontsel}
%%
%% This file is created by the preparatory data script `prepdata.sh` after it sets up the subdirectory list of valid text fonts. It sets the value of `\SIL@maxfont`.
\input{pickfont.tex}
%%
%% Color selection
%%
%% This value is set at the end of the color choice file created by the script. This is the number of color names found by the routine in `prepdata.sh` which extracts the color names.
\newcounter{SIL@maxcolno}
%%
%% The preparatory data script `prepdata.sh` retrieves the colors named in the **`svgnames`** option to the _xcolor_ package and instantiates them as a LaTeX case list in the file `svgnam.tex` as the command `\SIL@svgcolname`.
\input{svgnam.tex}
%%
%% The random font selection is done in a loop because of the need to test the values. This counter counts the iterations…
\newcounter{SIL@loopcount}
%%
%% …and this one the limit.
\newcounter{SIL@maxloop}
%%
%% The colors are selected numerically. This value is the background color of the spine of a book.
\newcounter{SIL@bgcolno}
%%
%% And this is the foreground color, used to typeset the title and author on the spine of a book.
\newcounter{SIL@fgcolno}
%%
%% To make sure that `\SIL@bgcolno` and `\SIL@fgcolno` are distinct, we will need to pick one “dark” and one “light”, crudely distinguished by examining their “brightness” (monochrome intensity value) using the formula due to (Dobovizki, 2008). From inspection, the modal point of the SVG values occurs around 0.6, so use use this to determine if the randomly-selected color is “dark” or “light”. Because it's a decimal fraction, we express it as a dimension and strip off the “pt” later.
\newlength{\SIL@splitpoint}
\setlength{\SIL@splitpoint}{0.6pt}
%%
%% We establish defaults for the background color…
\def\SIL@bgcol{White}
%%
%% …and the foreground color.
\def\SIL@fgcol{Black}
%%
%% The values computed by the `prepdata.sh` script and stored in `svgnam.tex` are decimal fractions, to they need to be retrieved as lengths. This is the background value…
\newlength{\SIL@bgval}
%%
%% …and the foreground value.
\newlength{\SIL@fgval}
%%
%% The “dark” or “light” test discussed above also needs to test if the values are too close to the splitpoint. By examination, if the values have an absolute difference of 0.2 they should be visually distinct enough. The difference is calculated and stored in this length variable, as it's a decimal fraction.
\newlength{\SIL@bgfgdiff}
%%
%% In the testing for colors, the nested conditionals set this switch true or false, so that it can be used to control the iteration through successive attempts to find suitable random values.
\newif\ifSIL@notyetcols
%%
%% Page border setup
%%
%% The page background color is set to a pale brown roughly matching the pine veneer of IKEA bookcases, with the inner page (behind the books) in a dark shadow brown. The technique for imposing a colored margin is due to [Ulrike Fischer](https://tex.stackexchange.com/questions/7725/how-to-set-a-certain-color-other-than-white-to-margin-areas) and uses the commands from the _eso-pic_ package.

%% Title and author dimensions
%%
%% The title and author need to be measured, and decisions are made about what size they need to be. The two layouts (author separately at the top, and author inline to title) are distinguished with the `\SIL@topauthor` conditional. If the title (with or without the author can fit on one line (rather than multiple lines) this is signalled with the `\SIL@titleoneline` conditional.
