+% \title{A couple of things involving environments}
+% \author{Will Robertson}

+%
+% \maketitle
+%
+% \begin{abstract}
+% This package provides two things, one for document authors and one for macro authors. For the document authors, a new method of defining environments that might be more convenient on occassion. And for the package writers, \pkg{amsmath}'s \cmd\collect@body\ command, and a long version of the same, \cmd\Collect@Body.
+% \end{abstract}
+%
+% \section{For the document author}
+%
+% \LaTeX's standard method of defining environments looks like this (ignoring arguments for now):
+% \codeline \cmd\newenvironment\marg{name}\marg{pre code}\marg{post code} .
+%
+% The advantage to using environments is that their contents is not treated as a macro argument, so there are less restrictions on what can exist inside, and the processing can be more efficient for long pieces of document text.
+%
+% The disadvantage of environments is that sometimes you really do want to collect up its body and apply some sort of command to the whole thing.
+% This package provides a way to define such environments,
+% \codeline \cmd\NewEnvironment\marg{name}\marg{macro code} ,\\
+% where \marg{macro code} has argument |#1| as everything inside the environment. \cmd\RenewEnvironment\ can be used to redefine a pre\"existing environment.
+%
+% As an example, consider putting a box around an environment. This requires more than a one-line solution without this package \note{And there're packages to do things much more nicely than I'm showing here anyway.}, but now we can write
+% \begin{example}{}
+% \NewEnvironment{test}{\fbox{\parbox{3cm}{#1}}}
+% \begin{test}
+% par\par
+% graf
+% \end{test}
+% \end{example}
+%
+% Now, this kind of environment definition makes collecting arguments a little cumbersome, but it's certainly possible. Arguments are defined with a separate macro that `gobbles up' the arguments inside the environment before the body is passed to \marg{macro code}.
+% \codeline \cmd\EnvironArgs\marg{name}\oarg{N.\ args}\oarg{opt. arg.}\marg{arg. macro code} \\
+% This follows the same syntax of defining a macro with several arguments and a possible optional argument at the beginning. Here's an example:
+% \begin{example}{}
+% \NewEnvironment{test}{(#1)\tmp}
+% \EnvironArgs{test}[2][before]{\def\tmp{\par---#1/#2---}}
+% \begin{test}{after}
+% par
+%
+% graf
+% \end{test}
+% \end{example}
+%
+% I've tried to ensure that whitespace is ignored at the appropriate places; without this additional code, there would be a space before `par' and after `graf' in the examples above.
+%
+% Note that arguments to the environment have to be explicitly passed into the macro code defining what the environment actually does. This is a bit of a shame, and a more convenient syntax could be
+% \begin{Verbatim}[gobble=4]
+% \NewEnv{test}[2][before]{\EnvBody\par---#1/#2---}
+% \end{Verbatim}
+% This is a probable future addition I'll make to the package.
+%
+% Oh, one last thing. These environments are defined to be ended by \cmd\ignorespacesafterend, which means that if they're used in a paragraph then the |\end{...}| command will gobble space after it. Let me know if this is a problem. It's kind of the way I like to do things but it might not fit everyone.
+%
+% \newpage
+% \section{For the macro author}
+%
+% The \pkg{amsmath} package contains a macro that facilitates the functionality in the previous section, which package writers may wish to use directly. The canonical command is \cmd\collect@body, which I've also defined in \cmd\long\ form to be useable for multi-paragraph environments (\cmd\Collect@Body). Here's how it's used:
+%
+% \begin{example}{}
+% \long\def\wrap#1{[#1]}
+% \newenvironment{test}{\Collect@Body\wrap}{}
+% \begin{test}
+% hello
+%
+% there
+% \end{test}
+% \end{example}
+%
+% And here's an example with environment arguments:
+%
+% \begin{example}{}
+% \long\def\wrap#1{[\arg#1]}
+% \def\arg#1{---#1---\par}
+% \newenvironment{test}{\Collect@Body\wrap}{}
+% \begin{test}{arg}
+% hello
+%
+% there
+% \end{test}
+% \end{example}

+% \begin{macro}{\collect@body}
+% Now, \pkg{amsmath} defines \cmd\collect@body\ for us. But that package may not be loaded, and we don't want to have to load the whole thing just for this one macro.

+ \Addto@Envbody{#1\end{#2}}%
+ \fi
+ \process@envbody}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\NewEnvironment}
+% \darg{Environment name}
+% \darg{Macro definition applied to env.\ body}
+% Here's our new environment definition macro. First of all wrap it up appropriately for new- or renew-
+% \begin{macrocode}
+\newcommand\NewEnvironment{%
+ \let\env@newenvironment\newenvironment
+ \let\env@newcommand\newcommand
+ \Make@Environment}
+\newcommand\RenewEnvironment{%
+ \let\env@newenvironment\renewenvironment
+ \let\env@newcommand\renewcommand
+ \Make@Environment}
+% \end{macrocode}
+% And here we go:
+% \begin{macrocode}
+\newcommand\Make@Environment[2]{%
+% \end{macrocode}
+% Initial `argument' parser, does nothing but remove leading space:
+% \begin{macrocode}
+ \expandafter\let\csname env@args@#1\endcsname\ignorespaces
+% \end{macrocode}
+% We use \cmd\Collect@Body\ to grab the argument (always \cmd\long)
+% \begin{macrocode}
+ \env@newenvironment{#1}{%
+ \expandafter\Collect@Body\csname env@@#1\endcsname}{\ignorespacesafterend}%
+% \end{macrocode}
+% Now precede the env.\ body by the argument parsing command, which may or may not be defined in \cmd\EnvironArgs\ (and \cmd\unskip\ removes trailing space)
+% \begin{macrocode}
+ \expandafter\env@newcommand\csname env@@#1\endcsname[1]{%
+ \csname env@@@#1\endcsname{%
+ \csname env@args@\@currenvir\endcsname##1\unskip}}%
+% \end{macrocode}
+% And then pass it all off to the environment macro (|#2|),
+% \begin{macrocode}
+ \expandafter\env@newcommand\csname env@@@#1\endcsname[1]{#2}}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\EnvironArgs}
+% \darg{Environment name}
+% \oarg{Number of arguments}
+% \oarg{Optional argument}
+% \darg{Argument macro code}
+% Tedious argument parsing:
+% \begin{macrocode}
+\newcommand\EnvironArgs[1]{%
+ \@ifnextchar[
+ {\Env@Args{#1}}
+ {\Env@Args{#1}[0]}}
+% \end{macrocode}
+% Tedious argument parsing:
+% \begin{macrocode}
+\long\def\Env@Args#1[#2]{%
+ \@ifnextchar[
+ {\Env@@@Args{#1}[#2]}
+ {\Env@@Args{#1}[#2]}}
+% \end{macrocode}
+% This is when there is no optional argument. In this case and the next, we simply define a command that is inserted when the argument body is processed (see \cmd\NewEnvironment). \cmd\ignorespaces\ removes leading space after the arguments.
+% \begin{macrocode}
+\long\def\Env@@Args#1[#2]#3{%
+ \expandafter\renewcommand\csname env@args@#1\endcsname[#2]{%
+ #3\ignorespaces}}
+% \end{macrocode}
+% Same as above when there is an optional argument:
+% \begin{macrocode}
+\long\def\Env@@@Args#1[#2][#3]#4{%
+ \expandafter\renewcommand\csname env@args@#1\endcsname[#2][#3]{%
+ #4\ignorespaces}}
