+            README for the `ifnextok' package
+       variant of \@ifnextchar not skipping spaces

+
+`ifnextok' deals with the behavior of LaTeX's internal 
+`\@ifnextchar' to skip blank spaces. This sometimes has surprising 
+or for some users really unwanted effects, especially with 
+brackets following `\\' where the user does not intend to specify 
+an optional argument, rather wants that brackets are printed.
+The package offers commands and options for modifying this 
+behavior, maybe limited to certain parts of the document source.
+
+KEYWORDS: macro programming, optional command arguments, 
+          manual line breaks

+%%
+%% === Outline ===
+%% The 'ifnextok' package deals with the behavior of 
+%% \LaTeX's internal `\@ifnextchar' to skip blank spaces. 
+%% This sometimes has surprising or for some users really 
+%% \emph{unwanted} effects, especially with brackets following 
+%% `\\' where the user does \emph{not} intend to specify an 
+%% optional argument, rather wants that brackets are \emph{printed.} 
+%% The package offers commands and options for modifying this 
+%% behavior, maybe limited to certain parts of the 
+%% document source. They are described in the sections below 
+%% together with the presentation of the implementation.
+%% 
+%% As after multiletter commands blank spaces are skipped anyway 
+%% (\TeX book p.~46f.), the package makes a difference only 
+%% for one-symbol commands such as |\\|, or for active characters 
+%% such as the double quote with \ctanpkgref{german}`.sty'
+%% and \ctanpkgref{babel}.
+%% 
+%% A little \strong{overview:}
+%% \begin{enumerate}
+%%  \item |\IfNextToken| is an alternative to `\@ifnextchar', 
+%%      not skipping spaces (Section~\ref{sec:main}). 
+%%      This macro is the \strong{low-level} 
+%%      backbone of all other modifications of \LaTeX\ commands.
+%%  \item |\IfStarNextToken| is an alternative to `\@ifstar', 
+%%      not skipping spaces, using `\IfNextToken' in lieu of 
+%%      `\@ifnextchar' (Section~\ref{sec:star}).
+%%  \item Some ``\strong{patching}" commands aim at modifying 
+%%      existing (\LaTeX) macros without specifying the resulting 
+%%      new definition explicitly 
+%%      (Sections~\ref{sec:patch} and \ref{sec:star}). 
+%%      As a package writer, 
+%%      you just must know which macros need to be modified
+%%      and specify their names as arguments for the patching macros. 
+%%  \item There are low-level commands 
+%%      |\INTstore| and |\INTrestore|
+%%      for undoing modifications of existing macros 
+%%      (Section~\ref{sec:stored}).
+%%  \item There are \strong{high-level} commands for modifying 
+%%      |\\| and selecting \LaTeX\ \strong{environments} 
+%%      to be affected (Section~\ref{sec:break}). 
+%%      Package \strong{options} execute some of them.
+%% \end{enumerate}
+%% (TODO: how command names are composed) %% 2011/05/23, v0.1
+%% 
+%% === Caveats ===
+%% Only a few of the commands have been tested so far, 
+%% and usage together with \ctanpkgref{amsmath}
+%% may require special care or fail altogether.
+%% 
+%% Switching into ``don't-skip-spaces" mode 
+%% \emph{two times} without switching back into normal mode 
+%% in between won't work with this version (v0.1)
+%% of the package (TODO: permanent aliases).
+%% You will get the 
+%% \[\texttt{Argument of <patching> has an extra }`}.'\]
+%% error. This also applies to commands that have been issued 
+%% by package options.
+%%
+%% === The Main Command \cs{IfNextToken} ===
+%% \label{sec:main}
+%% |IfNextToken<match>{<if>}{<else>}| is the obvious variant 
+%% of \LaTeX's internal `\@ifnextchar' executing <if> 
+%% if actually the \emph{``very next"} token is <mathc> 
+%% and executing <else> otherwise. If <match> is \emph{not} 
+%% a \emph{space token} (\LaTeX's `\@sptoken') but 
+%% the next token \emph{is}, <else> is executed; 
+%% while `\@ifnextchar' tries matching the next token 
+%% after ensuing space tokens. 
+\newcommand{\IfNextToken}[3]{%
+    \let\nextok@match=#1\def\nextok@if{#2}\def\nextok@else{#3}%
+    \futurelet\@let@token\nextok@decide}
+\def\nextok@decide{%
+    \ifx\@let@token\nextok@match \expandafter\nextok@if
+    \else                        \expandafter\nextok@else
+    \fi}
+%% |\NoNextSkipping| now switches into ``don't-skip-spaces" 
+%% mode ``altogether" (however ...):
+\newcommand*{\NoNextSkipping}{\let\@ifnextchar\IfNextToken}
+%% This appears so dangerous to me that I don't want to support it 
+%% much right now. |\RestoreNextSkipping| just switches back 
+%% to \LaTeX's original version, so some support for 
+%% \ctanpkgref{amsmath} may be missing here. 
+\newcommand*{\RestoreNextSkipping}{%
+    \let\@ifnextchar\kernel@ifnextchar}
+%% Actually, because `\NoNextSkipping' does not affect 
+%% `\kernel@ifnextchar', those of \LaTeX's commands using the latter 
+%% still will skip spaces (with package version v0.1). 
+%%
+%% === Patching Commands ===
+%% \label{sec:patch}
+%% |\INTpatch<replacer><macro>| replaces 
+%% something in the definition of <macro> according to 
+%% the replacement macro <replacer>. 
+%% This seems to work with the macros I thought of. 
+%% It does \emph{not} work when 
+%% (for replacing `\@ifnextchar')
+%% (a)~there are \emph{more} `\@ifnextchar's in the 
+%% macro to patch, or when (b)~an `\@ifnextchar' 
+%% is inside a pair of braces.
+\newcommand*{\INTpatch}[2]{%
+  \expandafter\expandafter\expandafter \def
+    \expandafter\expandafter\expandafter #2%
+      \expandafter\expandafter\expandafter {%
+        \expandafter #1#2#1}}
+%% |\NextTestPatch<macro>| replaces 
+%% `\@ifnextchar' in the definition of <macro> by 
+%% `\IfNextToken'. 
+\newcommand*{\NextTestPatch}{\INTpatch\nextok@patch}
+\def\nextok@patch#1\@ifnextchar#2\nextok@patch{#1\IfNextToken#2}
+%% 
+%% === Storing and Restoring ===
+%% \label{sec:stored}
+%% |\INTstore<macro>| stores the meaning of the macro <macro> 
+%% in a special name space. 
+\newcommand*{\INTstore}[1]{% 
+    \expandafter\let\csname\INT@name#1\endcsname#1}
+\newcommand*{\INT@name}{INTstore.\expandafter\@gobble\string}
+%% |\INTrestore<macro>| \emph{re}stores the meaning of <macro> 
+%% that is expected to having been stored with `\INTstore':
+\newcommand*{\INTrestore}[1]{%
+    \expandafter\let\expandafter#1\csname\INT@name#1\endcsname}
+%%
+%% === The Star Test ===
+%% \label{sec:star}
+%% Before a \LaTeX\ line-break command tests for an optional argument, 
+%% it tests for a star using `\@ifstar', which in turn invokes 
+%% `\@ifnextchar'. So already `\@ifstar' needs to be modified. 
+%% We do not so much want to change `\@ifstar' altogether, 
+%% rather we will replace it at some places by a non-skipping 
+%% variant |\IfStarNextToken|, using the patching command 
+%% |\StarTestPatch<macro>|.
+%% (`\@ifstar' has an argument and therefore cannot be patched as 
+%%  nicely as the line-break commands.)
+\newcommand*{\IfStarNextToken}[1]{\IfNextToken*{\@firstoftwo{#1}}}
+\newcommand*{\StarTestPatch}{\INTpatch\nextok@starpatch}
+%% The macro to be patched may contain a \cs{par} 
+%% (`\@centercr' is an example), so we need `\long':
+\long\def\nextok@starpatch#1\@ifstar#2\nextok@starpatch{%
+    #1\IfStarNextToken#2}
+%% |\StoreStarSkipping| stores the current meaning of 
+%% `\@ifstar' ...
+%% % is executed before changing `\@ifstar' temporarily:
+\newcommand*{\StoreStarSkipping}{\INTstore\@ifstar}
+%% ... so that it can be restored by |\RestoreStarSkipping|:
+\newcommand*{\RestoreStarSkipping}{\INTrestore\@ifstar}
+%% |\NoStarSkipping| renders `\@ifstar' non-skipping altogether:
+\newcommand*{\NoStarSkipping}{\let\@ifstar\IfStarNextToken}
+%% This again seems to be so dangerous that it will not be 
+%% supported much with package version v0.1 (by a package option). 
+%%
+%% === ``Manual" Line Breaks ===
+%% \label{sec:break}
+%% ==== Outline of Implementation ====
+%% In the first instance, the present package aims at rendering 
+%% |\\| a command that interpretes a left-hand square bracket 
+%% as a start of an optional argument only if the bracket is not 
+%% preceded by any other token (apart from the star in `\\*'), 
+%% especially not by a space token. 
+%% 
+%% Indeed, an author may expect that when a bracket opens in a 
+%% \emph{different} line than the `\\', then it will be 
+%% \emph{printed} rather than interpreted as an 
+%% \emph{optional-argument delimiter}
+%% (the package author has been such an author some times). 
+%% Now, when the bracket only is in a line \emph{following} 
+%% the line carrying the `\\', the end-line character 
+%% normally produces a space token (\TeX book p.~47), 
+%% so the present idea of implementation will cover 
+%% the case of a bracket in the next line.
+%% 
+%% In `latex.ltx', the names of the commands implementing the 
+%% line break have some ``pivot" part <pivot> that we can use 
+%% to patch them in a uniform way. They are two in each case: 
+%% The first starts with `\@<pivot>' and invokes `\@ifstar', 
+%% the second starts with `\@x<pivot>' and invokes the 
+%% left-hand-bracket test. Both of them need to be patched. 
+%% 
+%% ==== ``Normal" Manual Line Breaks ====
+%% \label{sec:newline}
+%% If I had been aware of the difficulties of this part, 
+%% I probably would not have started writing this package, 
+%% hoping it would be the work of about an hour. 
+%% 
+%% `\@xnewline' must be patched in order to get a non-skipping
+%% version of the bracket test, and this patch suffices for the 
+%% optional-argument goal. 
+%% 
+%% The `\@ifstar' call is in `\@normalcr'; the latter is invoked 
+%% by the robust version of `\\'. However, \LaTeX\ defines 
+%% `\@normalcr' by a `\let' referring to the result of 
+%% `\DeclareRobustCommand\\' ...
+%% 
+%% Things seem to be easier when |\\| calls `\@normalcr' 
+%% instead of `\\ ' (the latter is the effect of 
+%% `\DeclareRobustCommand'), 
+%% we are \textcolor{blue}{\strong{interchanging}} 
+%% the roles of `\\ ' and `\@normalcr' 
+%% (\textcolor{blue}{\strong{caution!}}). 
+%% Then we just need to control `\@normalcr':
+\def\\{\x@protect\\\protect\@normalcr}
+%% (Another \strong{Caveat:} I do not understand `\x@protect'.) %% v0.1
+%% 
+%% |\StoreNewlineSkipping| \emph{stores} the skipping behavior of |\\|
+%% outside special environments:
+\newcommand*{\StoreNewlineSkipping}{%
+    \INTstore\@normalcr \INTstore\@xnewline}
+%% |\RestoreNewlineSkipping| \emph{re}stores the skipping behavior of |\\|
+%% outside special environments:
+\newcommand*{\RestoreNewlineSkipping}{%
+    \INTrestore\@normalcr \INTrestore\@xnewline}
+%% |\NoNewlineSkipping| \emph{suppresses} skipping blank spaces with 
+%% |\\| outside special environments:
+\newcommand*{\NoNewlineSkipping}{%
+    \StarTestPatch\@normalcr \NextTestPatch\@xnewline}
+%%
+%% ==== Manual Line Breaks in \LaTeX\ Environments ====
+%% \label{sec:envs}
+%% The macros in the present section should modify \LaTeX's |\\| 
+%% in environments (<env> being one of:) 
+%% |center|, |tab|, |array|, and |tabular|. 
+%% These \emph{environment names} are the expected 
+%% \emph{arguments} of those macros. 
+%% However, argument |center| also affects the 
+%% |flushleft| and |flushright| environments, 
+%% and |array| and |tabular| should also affect 
+%% their enhanced variants from other \LaTeX\ packages. 
+%% When this internal structure of \LaTeX\ changes, 
+%% the present section may become obsolete ...
+%%
+%% |\INTactOnEnv{<action1>}{<action2>}{<env>}| 
+%% is the backbone of these macros. 
+%% <action1> and <action2> are one of 
+%% \[`\INTstore', `\INTrestore', `\StarTestPatch', 
+%% `\NextTestPatch'.\] 
+%% <action1> deals with `\@ifstar', 
+%% <action2> deals with `\@ifnextchar':
+\newcommand*{\INTactOnEnv}[3]{%
+    \expandafter#1\csname  @#3cr\endcsname
+    \expandafter#2\csname @x#3cr\endcsname}
+%% |\StoreSkippingCRs{<env>}| \emph{stores} the skipping behavior 
+%% of |\\| in environments <env>:
+\newcommand*{\StoreSkippingCRs}{%
+    \INTactOnEnv\INTstore\INTstore}
+%% |\RestoreSkippingCRs{<env>}| \emph{re}stores the skipping behavior 
+%% of |\\| in environments <env>:
+\newcommand*{\RestoreSkippingCRs}{%
+    \INTactOnEnv\INTrestore\INTrestore}
+%% |\NotSkippingCRs{<env>}| \emph{suppresses} space skipping
+%% of |\\| in environments <env>: 
+\newcommand*{\NotSkippingCRs}{%
+    \INTactOnEnv\StarTestPatch\NextTestPatch}
+%% % \NotSkippingCRs{center}
+%% \begin{center}
+%%    Do these commands work?\\ [\,Or do they not?\,]
+%% \end{center}
+%%
+%% === Package Options ===
+%% \label{sec:options} 
+%% ==== Behavior \emph{without} Options ====
+%% If the package is called without any option, 
+%% it only defines `\IfNextToken', `\IfStarNextToken' 
+%% and the other package-writer or user commands, 
+%% without actually changing behavior of any \LaTeX\ command.
+%%
+%% ==== Option `newline' ====
+%% Package option |newline| stores and disables space skipping for 
+%% |\\| in ``normal" mode according to Section~\ref{sec:newline}:
+\DeclareOption{newline}{\StoreNewlineSkipping\NoNewlineSkipping}
+%% 
+%% ==== Environments ====
+%% The next package options are just the environment names 
+%% according to Section~\ref{sec:envs} 
+%% (|center|, |tab|, |array|, |tabular|).
+%% Option |<env>| stores and disables the skipping behavior 
+%% of |\\| in <env> environments. 
+%% We abuse the our temporary macro `\nextok@match' from 
+%% Section~\ref{sec:main}:
+\def\nextok@match#1{%
+    \DeclareOption{#1}{\StoreSkippingCRs{#1}\NotSkippingCRs{#1}}}
+\nextok@match{center}
+\nextok@match{tab}
+\nextok@match{array}
+\nextok@match{tabular}
+%% ==== ``All Options" ====
+%% Package Option |all| has the same effect as 
+%% using the `newline' option and the environment package options 
+%% `center', `tab', `array', and `tabular' at once. 
+\def\nextok@match#1{\csname ds@#1\endcsname}
