-	\section{Updating the path variable}\label{sec:updating-path}
-	 \texttt{latexindent.pl} has a few scripts (available at \cite{latexindent-home}) that can
-	 update the \texttt{path} variables. Thank you to \cite{jasjuang} for this feature. If
-	 you're on a Linux or Mac machine, then you'll want \texttt{CMakeLists.txt} from
-	 \cite{latexindent-home}.
-	\subsection{Add to path for Linux}
-		To add \texttt{latexindent.pl} to the path for Linux, follow these steps:
-		\begin{enumerate}
-			\item download \texttt{latexindent.pl} and its associated modules,
-			      \texttt{defaultSettings.yaml}, to your chosen directory from \cite{latexindent-home} ;
-			\item within your directory, create a directory called \texttt{path-helper-files} and download

+  If you find that the \texttt{lookForAlignDelims} (as in \cref{subsec:align-at-delimiters}) does not work correctly
+  for your language, then you may with to use the \texttt{Unicode::GCString} module \announce*{2022-03-25}{Unicode::GCString}.
+  \index{perl!Unicode GCString module}
+  \index{switches!--GCString demonstration}
+
+  This can be loaded by calling \texttt{latexindent.pl} with the \texttt{GCString} switch
+  as in
+  \begin{commandshell}
+latexindent.pl --GCString myfile.tex
+\end{commandshell}
+  In this case, you will need to have the \texttt{Unicode::GCString} installed in your
+  \texttt{perl} distribution by using, for example,
+  \begin{commandshell}
+cpanm YAML::Tiny
+\end{commandshell}
+
+  Note: this switch does \emph{nothing} for \texttt{latexindent.exe} which loads the module
+  by default. Users of \texttt{latexindent.exe} should not see any difference in behaviour
+  whether they use this switch or not, as \texttt{latexindent.exe} loads the

-
-	\subsection{VSCode demonstration}
-		To use \texttt{latexindent-yaml-schema.json} with \texttt{VSCode}, you can use the

-		\begin{enumerate}
-			\item download \texttt{latexindent-yaml-schema.json} from the \texttt{documentation} folder of
-			      \cite{latexindent-home}, save it in whichever directory you would like, noting it for
-			      reference;
-			\item following the instructions from \cite{vscode-yaml-demo}, for example, you should install
-			      the VSCode YAML extension \cite{vscode-yaml-extentions};
-			\item set up your \texttt{settings.json} file using the directory you saved the file by
-			      adapting \cref{lst:settings.json}; on my Ubuntu laptop this file lives at
-			      \texttt{/home/cmhughes/.config/Code/User/settings.json}.

-		\begin{widepage}
-			\cmhlistingsfromfile{demonstrations/settings.json}[yaml-TCB]{\texttt{settings.json}}{lst:settings.json}

-
-		\begin{widepage}
-			\cmhlistingsfromfile{demonstrations/settings-alt.json}[yaml-TCB]{\texttt{settings-alt.json}}{lst:settings-alt.json}
-		\end{widepage}
-
-		Finally, if your TeX distribution is up to date, then
-		\texttt{latexindent-yaml-schema.json} \emph{should} be in the documentation folder of

-	 If you use conda you'll only need
-	 \begin{commandshell}
+         to check that the appropriate directory has been added to your \lstinline!%path%!.
+  \end{enumerate}
+  To \emph{remove} the directory from your \lstinline!%path%!, run
+  \texttt{remove-from-path.bat} as administrator.
+
+ \section{Batches of files}\label{sec:batches}
+
+  You can \announce*{2022-03-25}{batches of files details} instruct \texttt{latexindent.pl}
+  to operate on multiple files. For example, the following calls are all valid
+  \begin{commandshell}
+latexindent.pl myfile1.tex          
+latexindent.pl myfile1.tex myfile2.tex
+latexindent.pl myfile*.tex
+        \end{commandshell}
+
+  We note the following features of the script in relation to the switches detailed in
+  \cref{sec:how:to:use}.
+
+ \subsection{location of indent.log}
+  If the \texttt{-c} switch is \emph{not} active, then \texttt{indent.log} goes to the directory of the final file called.
+
+  If the \texttt{-c} switch \emph{is} active, then \texttt{indent.log} goes to the
+  specified directory.
+
+ \subsection{interaction with -w switch}
+  If the \texttt{-w} switch is active, as in
+  \begin{commandshell}
+latexindent.pl -w myfile*.tex
+\end{commandshell}
+  then files will be overwritten individually. Back-up files can be re-directed via the
+  \texttt{-c} switch.
+
+ \subsection{interaction with -o switch}
+  If \texttt{latexindent.pl} is called using the \texttt{-o} switch as in
+  \begin{commandshell}
+latexindent.pl myfile*.tex -o=my-output-file.tex 
+        \end{commandshell}
+  and there are multiple files to operate upon, then the \texttt{-o} switch is ignored
+  because there is only \emph{one} output file specified.
+
+  More generally, if the \texttt{-o} switch does \emph{not} have a \texttt{+} symbol at the
+  beginning, then the \texttt{-o} switch will be ignored, and is turned it off.
+
+  For example
+  \begin{commandshell}
+latexindent.pl myfile*.tex -o=+myfile
+\end{commandshell}
+  \emph{will} work fine because \emph{each} \texttt{.tex} file will output to
+  \texttt{<basename>myfile.tex}
+
+  Similarly,
+  \begin{commandshell}
+latexindent.pl myfile*.tex -o=++
+\end{commandshell}
+  \emph{will} work because the `existence check/incrementation' routine will be applied.
+
+ \subsection{interaction with lines switch}
+  This behaves as expected by attempting to operate on the line numbers specified for each file. See
+  the examples in \cref{sec:line-switch}.
+
+ \subsection{interaction with check switches}
+  The exit codes for \texttt{latexindent.pl} are given in \vref{tab:exit-codes}.
+
+  When operating on multiple files with the check switch active, as in
+  \begin{commandshell}
+latexindent.pl myfile*.tex --check
+        \end{commandshell}
+  then
+  \begin{itemize}
+   \item exit code 0 means that the text from \emph{none} of the files has been changed;
+   \item exit code 1 means that the text from \emph{at least one} of the files been file changed.
+  \end{itemize}
+
+  The interaction with \texttt{checkv} switch is as in the check switch, but with verbose
+  output.
+
+ \subsection{when a file does not exist}
+  What happens if one of the files can not be operated upon?
+  \begin{itemize}
+   \item if at least one of the files does not exist and \texttt{latexindent.pl} has been called
+         to act upon multiple files, then the exit code is 3; note that \texttt{latexindent.pl}
+         will try to operate on each file that it is called upon, and will not exit with a fatal
+         message in this case;
+   \item if at least one of the files can not be read and \texttt{latexindent.pl} has been called
+         to act upon multiple files, then the exit code is 4; note that \texttt{latexindent.pl}
+         will try to operate on each file that it is called upon, and will not exit with a fatal
+         message in this case;
+   \item if \texttt{latexindent.pl} has been told to operate on multiple files, and some do not
+         exist and some cannot be read, then the exit code will be either 3 or 4, depending upon
+         which it scenario it encountered most recently.
+  \end{itemize}

 \section{Conclusions and known limitations}\label{sec:knownlimitations}
  There are a number of known limitations of the script, and almost certainly quite a few
- that are \emph{unknown}!
-
- For example, with reference to the multicolumn alignment routine in
- \vref{lst:tabular2-mod2}, when working with code blocks in which multicolumn commands
- overlap, the algorithm can fail.
-
- Another limitation is to do with efficiency, particularly when the \texttt{-m} switch is
- active, as this adds many checks and processes. The current implementation relies upon
- finding and storing \emph{every} code block (see the discussion on
- \cpageref{page:phases}); I hope that, in a future version, only \emph{nested} code blocks
- will need to be stored in the `packing' phase, and that this will improve the efficiency
- of the script.

+ \begin{description}
+  \item[multicolumn alignment] when working with code blocks in which multicolumn commands
+   overlap, the algorithm can fail; see \vref{lst:tabular2-mod2}.
+  \item[text wrap] routine operates \emph{before} indentation occurs; this means that it is
+   likely that your final, indented, text wrapped text may exceed the value of
+   \texttt{columns} that you specify; see \vref{subsec:textwrapping}.

+         the end of the line; this is undesirable, clearly!
+   \item \cref{lst:finetuning4-mod2} has fine-tuned the trailing comment matching, and says that
+         \% cannot
+         be immediately preceeded by the words `Handbook', `for' or `Spoken', which means that
+         none of the \% symbols have been treated as trailing comments, and the output is
+         desirable.
+  \end{itemize}
+
+  Another approach to this situation, which does not use \texttt{fineTuning}, is to use
+  \texttt{noIndentBlock} which we discussed in \vref{lst:noIndentBlock}; using the settings

-	After I blogged about it on the \TeX{} stack exchange \cite{cmhblog} I received some
-	positive feedback and follow-up feature requests. A big thank you to Harish Kumar
-	\cite{harish} who helped to develop and test the initial versions of the script.

-	The \texttt{YAML}-based interface of \texttt{latexindent.pl} was inspired by the

 \subsection{The two types of replacements}
-	There are two types of replacements:
-	\begin{enumerate}
-		\item \emph{string}-based replacements, which replace the string in
-		      \emph{this} with the string in \emph{that}.
-		      If you specify \texttt{this} and you do not specify \texttt{that}, then the \texttt{that}
-		      field will be assumed to be empty.
-		      \index{regular expressions!replacement switch, -r}
-		\item \emph{regex}-based replacements, which use the \texttt{substitution} field.
-	\end{enumerate}
-	We will demonstrate both in the examples that follow.
-
-	\texttt{latexindent.pl} chooses which type of replacement to make based on which fields
-	have been specified; if the \texttt{this} field is specified, then it will make
-	\emph{string}-based replacements, regardless of if \texttt{substitution} is present or
-	not.

-		we may abbreviate to \emph{regex} in what follows. This manual is not intended to be a
-		tutorial on regular expressions; you might like to read, for example,
-		\cite{masteringregexp} for a detailed covering of the topic. With reference to
-		\cref{lst:colsep1}, we do note the following:
-		\begin{itemize}
-			\item the general form of the \texttt{substitution} field is
-			      \lstinline!s/regex/replacement/modifiers!. You can place any regular expression you like
-			      within this;
-			\item we have `escaped' the backslash by using \lstinline!\\!
-			\item we have used \lstinline!\d+! to represent \emph{at least} one digit
-			\item the \texttt{s} \emph{modifier} (in the \texttt{sg} at the end of the line) instructs
-			      \texttt{latexindent.pl} to treat your file as one single line;
-			\item the \texttt{g} \emph{modifier} (in the \texttt{sg} at the end of the line) instructs
-			      \texttt{latexindent.pl} to make the substitution \emph{globally} throughout your file;
-			      you might try removing the \texttt{g} modifier from \cref{lst:colsep1} and observing the

-	relation to oneSentencePerLine} environments, preamble and trailing comments have been
-	accounted for; this means that any characters within these types of code blocks will not
-	be part of the sentence manipulation routine.

-	For example, if we begin with the \texttt{.tex} file in \cref{lst:multiple-sentences3},
-	and run the command \index{switches!-l demonstration} \index{switches!-m demonstration}

-		If you ask \texttt{latexindent.pl} to add a line break (possibly with a comment) using a
-		poly-switch value of $1$ (or $2$ or $3$), it will only do so if necessary. For example,

 \subsubsection{Poly-switches for other code blocks}
-	Rather than repeat the examples shown for the environment code blocks (in
-	\vref{sec:modifylinebreaks-environments}), we choose to detail the poly-switches for all
-	other code blocks in \cref{tab:poly-switch-mapping}; note that each and every one of
-	these poly-switches is \emph{off by default}, i.e, set to \texttt{0}.
-
-	Note also that, by design, line breaks involving, \texttt{filecontents} and
-	`comment-marked' code blocks (\vref{lst:alignmentmarkup}) can \emph{not} be modified
-	using \texttt{latexindent.pl}. \announce{2019-05-05}*{verbatim poly-switch} However,
-	there are two poly-switches available for \texttt{verbatim} code blocks: environments
-	(\vref{lst:verbatimEnvironments}), commands (\vref{lst:verbatimCommands}) and
-	\texttt{specialBeginEnd} (\vref{lst:special-verb1-yaml}).

-
-	In \cref{lst:nested-env-mlb1}, let's first of all note that both environments have

-	\texttt{EndStartsOnOwnLine} appears to have won the conflict, as \lstinline!\end{one}!
-	has had its leading line break removed.
-
-	To understand it, let's talk about the three basic phases \label{page:phases}of
-	\texttt{latexindent.pl}:
-	\begin{enumerate}
-		\item Phase 1: packing, in which code blocks are replaced with unique ids, working from
-		      \emph{the inside to the outside}, and then sequentially -- for example, in
-		      \cref{lst:nested-env}, the \texttt{two} environment is found \emph{before} the
-		      \texttt{one} environment; if the -m switch is active, then during this phase:
-		      \begin{itemize}
-			      \item line breaks at the beginning of the \texttt{body} can be added (if
-			            \texttt{BodyStartsOnOwnLine} is $1$ or $2$) or removed (if \texttt{BodyStartsOnOwnLine}
-			            is $-1$);
-			      \item line breaks at the end of the body can be added (if \texttt{EndStartsOnOwnLine} is $1$ or
-			            $2$) or removed (if \texttt{EndStartsOnOwnLine} is $-1$);
-			      \item line breaks after the end statement can be added (if \texttt{EndFinishesWithLineBreak} is
-			            $1$ or $2$).
-		      \end{itemize}
-		\item Phase 2: indentation, in which white space is added to the begin, body, and end
-		      statements;
-		\item Phase 3: unpacking, in which unique ids are replaced by their \emph{indented} code
-		      blocks; if the -m switch is active, then during this phase,
-		      \begin{itemize}
-			      \item line breaks before \texttt{begin} statements can be added or removed (depending upon
-			            \texttt{BeginStartsOnOwnLine});
-			      \item line breaks after \emph{end} statements can be removed but \emph{NOT} added (see
-			            \texttt{EndFinishesWithLineBreak}).
-		      \end{itemize}
-	\end{enumerate}
-
-	With reference to \cref{lst:nested-env-mlb1}, this means that during Phase 1:
-	\begin{itemize}
-		\item the \texttt{two} environment is found first, and the line break ahead of the
-		      \lstinline!\end{two}! statement is removed because \texttt{EndStartsOnOwnLine} is set to
-		      $-1$. Importantly, because, \emph{at this stage}, \lstinline!\end{two}! \emph{does}
-		      finish with a line break, \texttt{EndFinishesWithLineBreak} causes no action.
-		\item next, the \texttt{one} environment is found; the line break ahead of
-		      \lstinline!\end{one}! is removed because \texttt{EndStartsOnOwnLine} is set to $-1$.
-	\end{itemize}
-	The indentation is done in Phase 2; in Phase 3 \emph{there is no option to add a line
-	break after the \lstinline!end! statements}. We can justify this by remembering that
-	during Phase 3, the \texttt{one} environment will be found and processed first, followed
-	by the \texttt{two} environment. If the \texttt{two} environment were to add a line break
-	after the
-	\lstinline!\end{two}! statement, then \texttt{latexindent.pl} would have no way of
-	knowing how much indentation to add to the subsequent text (in this case,
-	\lstinline!\end{one}!).

+ An overview of how the text wrapping feature works:
+ \begin{enumerate}
+  \item the default value of \texttt{columns} is 0, which means that text wrapping will
+        \emph{not} happen by default;
+  \item it happens \emph{after} verbatim blocks have been found;
+  \item it happens \emph{after} the oneSentencePerLine routine (see
+        \cref{sec:onesentenceperline});
+  \item it happens \emph{before} all of the other code blocks are found and does \emph{not}
+        operate on a per-code-block basis; this means that, including indentation, you may
+        receive a column width wider than that which you specify in \texttt{columns}
+  \item code blocks to be text wrapped will:
+        \begin{enumerate}
+         \item \emph{follow} the fields specified in \texttt{blocksFollow}
+         \item \emph{begin} with the fields specified in \texttt{blocksBeginWith}
+         \item \emph{end} before the fields specified in \texttt{blocksEndBefore}
+        \end{enumerate}
+  \item setting \texttt{columns} to a value $>0$ will text wrap blocks by first removing line
+        breaks, and then wrapping according to the specified value of \texttt{columns};
+  \item setting \texttt{columns} to $-1$ will \emph{only} remove line breaks within the text wrap
+        block;
+  \item by default, the text wrapping routine will remove line breaks within text blocks because
+        \texttt{removeBlockLineBreaks} is set to 1; switch it to 0 if you wish to change this.
+ \end{enumerate}
+
+ We demonstrate this feature using a series of examples.
