 # actuarialangle
 
-This package defines a single command `\actuarialangle` to typeset
-nice looking "angles" in actuarial and financial notation, such as in
-symbols for the present value of an annuity.
+Package `actuarialangle` provides commands to typeset the "angle"
+symbol denoting a duration in actuarial notation, such as in symbols
+for the present value of certain or life annuities and an overhead
+square bracket used to emphasize joint status in symbols of life
+contingencies.

-## Author
+## Version
+
+2.0 (2017-04-10)
 
-The code in this package was given to me (Vincent Goulet
-<vincent.goulet@act.ulaval.ca>) by a former colleague who would simply
-copy it in the preamble of all his documents needing an "angle"
-symbol. The actual author of the code is unknown.
+## Author
 
-My sole contribution was to make a package out of the code.
+Vincent Goulet <vincent.goulet@act.ulaval.ca>, based on code from an
+unknown author for `\actuarialangle` and friends.
 
 ## Installation
 
 The package is part of TeX Live and MiKTeX. If it is not already
-installed on your system, copy `actuarialangle.sty` where LaTeX can
-find it.
-
-## Usage
-
-Load the package as usual with
-
-    \usepackage{actuarialangle}
+installed on your system, run `actuarialangle.dtx` through LaTeX with,
+for example,
 
-Then, in math mode, use
+    pdflatex actuarialangle.dtx
 
-    \actuarialangle{n}
+and copy `actuarialangle.sty` where LaTeX can find it.
 
-to typeset "angle n". For a complete present value symbol, use
-something like
+## Documentation
 
-    a_{\actuarialangle{n}}
-
-You will most likely want to use the following shortcuts:
-
-- `\angl`  for `\actuarialangle`
-- `\angln` for `\angl{n}`
-- `\anglr` for `\angl{r}`
+File `actuarialangle.pdf` contains the complete documentation of the
+package. If needed, the documentation can be generated from the
+sources using the following commands:
 
+    pdflatex actuarialangle.dtx
+    makeindex -s gglo.ist -o actuarialangle.gls actuarialangle.glo
+    pdflatex actuarialangle.dtx

+%
+% \begin{abstract}
+%   Package \pkg{actuarialangle} provides commands to typeset the
+%   ``angle'' symbol denoting a duration $n$ in actuarial notation, as
+%   in $\angln$, and an overhead angle bracket, as in $\group{xy}$.
+% \end{abstract}
+%
+% \section{Introduction}
+%
+% This package defines commands to typeset two symbols used in
+% actuarial notation for life contingencies and financial mathematics.
+% The first is the ``angle'' denoting a duration in the present value
+% of an insurance or annuity: $\angln$. The second is an overhead
+% angle bracket (or ``roof'') used to emphasize joint status when
+% ambiguity is possible: $\group{xy}$. The bracket is normally used
+% with a precedence number above. Facilities to position such numbers
+% are provided by package \pkg{actuarialsymbol}
+% \citep{actuarialsymbol}.
+%
+% For additional details on actuarial notation for life contingencies,
+% see \citet{Bowers:2e:1997}.
+%
+% \section{Package options}
+% \label{sec:options}
+%
+% The package offers the following options:
+% \begin{description}
+% \item[\mdseries\ttfamily thinspace] insert a thin space of 1mu
+%   between the material under the angle and the right descender; this
+%   is the default starting with version 2.0 of the package;
+% \item[\mdseries\ttfamily thickspace] insert a thicker space of 2mu
+%   between the material under the angle and the right descender; this
+%   was the value used in versions of the package prior to 2.0;
+% \item[\mdseries\ttfamily nobracket] do not define command
+%   \cmd{\overanglebracket}; this option also prevents loading of
+%   package \pkg{pict2e}.
+% \end{description}
+% We provide option |nobracket| in case the bracket symbol is not
+% needed and \pkg{pict2e} \citep{pict2e} interferes with other
+% packages. Loading the package with
+% \begin{quote}
+%   |\usepackage[thickspace,nobracket]{actuarialangle}|
+% \end{quote}
+% yields the behaviour of versions prior to 2.0, but for the defunct
+% features mentioned in \autoref{sec:defunct}.
+%
+% \section{Package features}
+%\label{sec:features}
+%
+% \begin{DescribeMacro}{\actuarialangle}
+%   In math mode, the command
+%   \begin{quote}
+%     |\actuarialangle|\marg{duration}
+%   \end{quote}
+%   composes an angle symbol around \meta{duration}. This is the
+%   ``raw'' command that does not insert any space between
+%   \meta{duration} and the right descender of the angle. The symbol
+%   scales gracefully if the command is ever used outside of a
+%   first-level subscript.
+%   \begin{demo}
+%     \begin{texample}
+%       |\actuarialangle{n} \quad| \\
+%       |a_{\actuarialangle{n}}|
+%       \producing
+%       $\actuarialangle{n} \quad a_{\actuarialangle{n}}$
+%     \end{texample}
+%   \end{demo}
+% \end{DescribeMacro}
+%
+% \begin{DescribeMacro}{\angl}
+% \begin{DescribeMacro}{\angln}
+% \begin{DescribeMacro}{\anglr}
+% \begin{DescribeMacro}{\anglk}
+%   Users are expected to typeset angle symbols with the command
+%   \begin{quote}
+%     |\angl|\marg{duration}
+%   \end{quote}
+%   In contrast to \cmd{\actuarialangle}, this command inserts some
+%   thin space (by default or with package option |thinspace|) or
+%   thick space (with package option |thinkspace|) between
+%   \marg{duration} and the right descender.
+%   \begin{demo}
+%     \begin{texample}
+%       |% with option thinspace:| \\
+%       |\angl{n} \quad a_{\angl{n}}|
+%       \producing
+%       $\angl{n} \quad a_{\angl{n}}$
+%     \end{texample}
+%     \begin{texample}
+%       |% with option thickspace| \\
+%       |\angl{n} \quad a_{\angl{n}}|
+%       \producing
+%       $\angl{n\mkern1mu} \quad a_{\angl{n\mkern1mu}}$
+%     \end{texample}
+%   \end{demo}
+%   Commands \cmd{\angln}, \cmd{\anglr} and \cmd{\anglk} are shortcuts
+%   for the common cases \cmd{\angl}|{n}|, \cmd{\angl}|{r}| and
+%   \cmd{\angl}|{k}|, respectively.
+% \end{DescribeMacro}
+% \end{DescribeMacro}
+% \end{DescribeMacro}
+% \end{DescribeMacro}
+%
+% \begin{DescribeMacro}{\overanglebracket}
+% \begin{DescribeMacro}{\group}
+%   The command
+%   \begin{quote}
+%     \cmd{\overanglebracket}\marg{statuses}
+%   \end{quote}
+%   composes an angle bracket (``roof'') above \meta{statuses}. The
+%   rule thickness and spacing relative to the statuses match those of
+%   the angle symbol. Command \cmd{\group} is a convenient alias for
+%   \cmd{\overanglebracket}.
+%   \begin{demo}
+%     \begin{texample}
+%       |\group{xy} \quad| \\
+%       |A_{\group{xy}:\angln}|
+%       \producing
+%       $\group{xy} \quad A_{\group{xy}:\angln}$
+%     \end{texample}
+%   \end{demo}
+% \end{DescribeMacro}
+% \end{DescribeMacro}
+%
+% \section{Defunct features}
+% \label{sec:defunct}
+%
+% Versions prior to 2.0 of the package included the undocumented
+% commands
+% \begin{quote}
+%   \cmd{\topprecedence} (with alias \cmd{\lift}) \\
+%   \cmd{\vartopprecedence} \\
+%   \cmd{\bottomprecedence} \\
+%   \cmd{\varbottomprecedence}
+% \end{quote}
+% to typeset precedence numbers above and below statuses in subscript
+% of an actuarial symbol. These features have been moved --- and
+% improved on the way --- to package \pkg{actuarialsymbol}
+% \citep{actuarialsymbol}.

+%
+% The original author of macros \cmd{\actuarialangle} and

+%
+% \begin{macro}{\actuarialangle}
+%   We first define the ``raw'' user level command.
+%    \begin{macrocode}
+\DeclareRobustCommand{\actuarialangle}{\mathpalette\acta@angle}
+%    \end{macrocode}
+%   The operation of \cmd{\mathpalette} ensures that proper sizing the
+%   command is ever used outside of a first-level subscript.
+% \end{macro}
+%
+% \begin{macro}{\acta@angle}
+%   Next we define the real workhorse.
+%    \begin{macrocode}

+% Add a bit of preceding space.
+%    \begin{macrocode}

+%   We need many nested boxes here: first a vbox to stack the horizontal

+% \section{Over angle bracket}
+% \label{sec:implementation:overanglebracket}
+%
+% The code of this section is executed only if |\acta@bracket| is
+% |true|, that is when the package is \emph{not} loaded with option
+% |nobracket|.
+%    \begin{macrocode}
+\ifacta@bracket
+%    \end{macrocode}
+% Drawing the angle bracket requires package \pkg{pict2e}

+%    \end{macrocode}
+%   We use \cmd{\mathpalette} as above.

+%
+% \begin{macro}{\acta@anglebracket}
+%   The workhorse is |\acta@anglebracket|. It builds the bracket
+%   symbol with path lines.
+%    \begin{macrocode}
+  \def\acta@anglebracket#1#2{%
+%    \end{macrocode}
+%   Box zero contains the material under the bracket. The width of this
+%   box will determine the width of the flat part of the bracket and the
+%   height, the length of the descenders. Hence we store these values.

+    \setbox\z@\hbox{$\m@th#1#2$}
+    \dimen0\wd\z@ \dimen1\ht\z@
+%    \end{macrocode}
+%   Box two contains the bracket itself. It is drawn in three parts

 %%
-%% This package defines a single command \actuarialangle to typeset
-%% nice looking "angles" in present value of an annuity symbols common
-%% in actuarial and financial notation.
-%%
-%% USAGE
-%%
-%% In math mode
-%%
-%%   \actuarialangle{n}  
-%%
-%% to typeset "angle n". For a complete present value symbol,
-%% something like
-%%
-%%   a_{\actuarialangle{n}}
-%%
-%% SHORTCUTS
-%%
-%% You will most likely want to use the following shortcuts:
-%%
-%% \angl  for \actuarialangle
-%% \angln for \angl{n}

-\def\actuarialangle{\mathpalette\act@angle}
-%
-% The operation of \mathpalette causes \actuarialangle{30} to expand
-% to a mathchoice. This ensures that proper sizing will be done if
-% \angle is ever used outside of a first-level subscript:
-%
-% \mathchoice{%
-% {\act@angle\displaystyle{30}}%
-% {\act@angle\textstyle{30}}%
-% {\act@angle\scriptstyle{30}}%
-% {\act@angle\scriptscriptstyle{30}}%
-% }
-%
-\def\act@angle#1#2{%
-\mathord{%
-\mkern1mu % Add a bit of preceding space
-\vbox{\hrule \hbox{\vbox{%
-% This amount of vertical space is the normal space for \overline in a
-% subscript:
-\kern3\fontdimen8\scriptfont\thr@@
-\hbox{$#1#2\m@th$}}%
-% Make the right-hand rule extend down to the depth of a parenthesis
-% even if the symbol under the angle does not have a descender:
-\setbox\z@\hbox{$#1()$}\vrule depth\dp\z@}}%
-\mkern1mu}% Add a bit of following space

-% \topprecedence puts a precedence number above an item, smashed so
-% that the apparent height of the item is its normal height.
-%
-\def\topprecedence#1#2{\mathpalette{\preced@ t{}{#1}}{#2}}
-%
-% Put a multiplier in the empty set of braces to increase
-% the spacing between the precedence number and the
-% symbol to which it applies, e.g.
-%
-% \def\topprecedence#1#2{\mathpalette{\preced@ t{2.5}{#1}}{#2}}
-%
-% This also applies for \botprecedence and \vartopprecedence.
-% If it is desired that all precedence numbers fall at the
-% same height, regardless of whether there is an hrule between
-% them and the symbol to which they apply, then make
-% \topprecedence the same as \vartopprecedence.
-%
-\def\botprecedence#1#2{\mathpalette{\preced@ b{}{#1}}{#2}}
-%
-% \vartopprecedence provides extra space below the top
-% symbol, to accommodate an intervening hrule.
-%
-\def\vartopprecedence#1#2{\mathpalette{\preced@ t3{#1}}{#2}}
-%
-% In \preced@, #1 is `t' for top or `b' for bottom, #2 is a
-% multiplier for the space between the top and bottom symbols (may
-% be empty), #3 is the first argument from the user, #4 is
-% \displaystyle or \textstyle or \scriptstyle or
-% \scriptscriptstyle, from \mathpalette, and #5 is the second
-% argument given by the user. This peculiar ordering of the
-% arguments is done to work around the restriction of \mathpalette
-% that it only reads 2 arguments.
-%
-\def\preced@#1#2#3#4#5{%
