+%<*2ekernel>
+% \end{macrocode}
+%
+% The `2ekernel' code ensures that a |\usepackage{autoerr}| is
+% essentially ignored if a `full' format is being used that has
+% the error messages already in the format.
+%
+% These days we don't support autoloading approach any longer, but
+% this part bit is kept in case it is used in old documents.

+% \subsection{General commands}
+%
+% \begin{macro}{\MessageBreak}
+% This command prints a new-line inside a message, followed by a
+% continuation line begun with |\@msg@continuation|. Normally it is
+% defined to be |\relax|, but inside messages, it is let to
+% |\@message@break|.
+% \begin{macrocode}
+\let\MessageBreak\relax
+% \end{macrocode}
+% \end{macro}
+%
+% \changes{v1.2g}{1994/11/04}{Added \cs{set@display@protect} to
+% \cs{Generic*} commands. ASAJ.}
+%
+% \begin{macro}{\GenericInfo}
+% This takes two arguments: a continuation and a message, and sends
+% the result to the log file.
+% \begin{macrocode}
+\DeclareRobustCommand{\GenericInfo}[2]{%
+ \begingroup
+ \def\MessageBreak{^^J#1}%
+ \set@display@protect
+ \immediate\write\m@ne{#2\on@line.}%
+ \endgroup
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\GenericWarning}
+% This takes two arguments: a continuation and a message, and sends
+% the result to the screen.
+% \begin{macrocode}
+\DeclareRobustCommand{\GenericWarning}[2]{%
+ \begingroup
+ \def\MessageBreak{^^J#1}%
+ \set@display@protect
+ \immediate\write\@unused{^^J#2\on@line.^^J}%
+ \endgroup
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}{\GenericError}
+% This macro takes four arguments: a continuation,
+% an error message, where to go for further information, and the help
+% information. It displays the error message, and sets the error help
+% (the result of typing |h| to the prompt), and does a horrible hack
+% to turn the last context line (which by default is the only context
+% line) into just three dots. This could be made more efficient.
+% \changes{v1.2d}{1994/05/22}
+% {(DPC) New version using long command name.}

+%
+% Unfortunately \TeX\ versions older than 3.141 have a bug which means
+% that |^^J| does not force a linebreak in |\message| and |\errmessage|
+% commands. So for these old \TeX's we use |\typeout| to produce the
+% message, and then have an empty |\errmessage| command. This causes an
+% extra line of the form
+%\begin{verbatim}
+%! .
+%\end{verbatim}
+% To appear on the terminal, but if you do not like it, you can always
+% upgrade your \TeX! In order for your format to use this version, you
+% must define the macro |\@TeXversion| to be the version number, e.g.,
+% 3.14 of the underlying \TeX. See the comments in
+% \texttt{ltdircheck.dtx}.
+% \begin{macrocode}

+% \begin{macro}{\PackageError}
+% \begin{macro}{\PackageWarning}
+% \begin{macro}{\PackageWarningNoLine}
+% \begin{macro}{\PackageInfo}
+% \begin{macro}{\ClassError}
+% \begin{macro}{\ClassWarning}
+% \begin{macro}{\ClassWarningNoLine}
+% \begin{macro}{\ClassInfo}
+% These commands are intended for use by package and class writers, to
+% give information to authors. The syntax is:
+% \begin{quote}
+% |\PackageError{|\meta{package}|}{|^^A
+% \meta{error}|}{|\meta{help}|}| \\
+% |\PackageWarning{|\meta{package}|}{|\meta{warning}|}| \\
+% |\PackageWarningNoLine{|\meta{package}|}{|\meta{warning}|}| \\
+% |\PackageInfo{|\meta{package}|}{|\meta{info}|}|
+% \end{quote}
+% and similarly for classes. The |Error| commands print the
+% \meta{error} message, and present the interactive prompt; if the
+% author types |h|, then the \meta{help} information is displayed.
+% The |Warning| commands produce a warning but do not present the
+% interactive prompt. The |WarningNoLine| commands do the same,
+% but don't print the input line number. The |Info| commands write
+% the message to the
+% |log| file. Within the messages, the command
+% |\MessageBreak| can be used to
+% break a line, |\protect| can be used to protect command names,
+% and |\space| is a space, for example:
+% \begin{verbatim}
+% \newcommand{\foo}{FOO}
+% \PackageWarning{ethel}{%
+% Your hovercraft is full of eels,\MessageBreak
+% and \protect\foo\space is \foo}
+% \end{verbatim}
+% produces:
+% \begin{verbatim}
+% Package ethel warning: Your hovercraft is full of eels,
+% (ethel) and \foo is FOO on input line 54.
+% \end{verbatim}

+% Issued by commands that don't work correctly within math (like
+% |\item|). There is no real error recovery happening, e.g., the
+% user might get additional errors afterwards.
+% \begin{macrocode}

+% {(RmS) Error message for invalid input characters.}
+% \changes{v1.0d}{1994/03/28}
+% {(DPC) Comment out (use catcode15 instead)}
+% An error for use with invalid characters. This is commented
+% out, since we decided to use catcode 15 instead.
+% \begin{macrocode}

+% As well as the above error commands some error messages are directly
+% coded to save space. The messages already present in \LaTeX2.09
+% include:
+%
+% |Environment --- undefined|\\
+% Issued by |\begin| for undefined environment.
+%
+% |Tab overflow|\\
+% Occurs in |\=| when maximum number of tabs exceeded.
+%
+% |\< in mid line|\\
+% Occurs in |\<| when it appears in middle of line.
+%
+% |Float(s) lost|\\
+% In output routine, caused by a float environment or
+% |\marginpar| occurring in inner vertical mode.
