%% == Usage with 'myfilist' ==
%% \label{sec:myfilist}
%% === Basically ===
%% \label{sec:basic}
%% In order to get a reduced and/or rearranged list of used files
%% with the \ctanpkgref{myfilist} package,
%% `longnamefilelist.sty' must be loaded earlier than
%% `myfilist.sty'. This is due to a kind of limitation of the latter,
%% it \emph{issues} `\listfiles' (TODO).
%% Therefore `\listfiles' must be modified earlier---or \emph{issued} earlier,
%% in this case the `\listfiles' in `myfilist.sty' does nothing.
%% The file `SrcFILEs.txt' accompanying the distribution of 'longnamefilelist',
%% e.g., can be generated by running the following file `srcfiles.tex'
%% with \LaTeX:
%% %% v0.1b 2012/03/14 avoid right-arrow substitution TODO:
%% \begin{quotation}\tt\small
%% \expandafter\def\expandafter\{\expandafter{\string{}
%% \expandafter\def\expandafter\}\expandafter{\string}}
%% \obeyspaces\obeylines
%% \cs{ProvidesFile}\{srcfiles.tex\}[2012/03/12
%% ~ file infos -\empty> SrcFILEs.txt]
%% \cs{RequirePackage}\{longnamefilelist\}
%% \cs{listfiles}[16]
%% \cs{RequirePackage}\{myfilist\}
%% \%\% documentation:
%% \cs{ReadFileInfos}\{longnamefilelist\}
%% \%\% documentation settings and auxiliaries:
%% \cs{ReadPackageInfos}\{fifinddo,makedoc,niceverb\}
%% \cs{ReadFileInfos}\{makedoc.cfg,mdoccorr.cfg,srcfiles\}
%% \cs{ListInfos}[SrcFILEs.txt]
%% \end{quotation}
%%
%% === Shorthand ===
%% \label{sec:short}
%% In the above example, the 'myfilist' command `\EmptyFileList'
%% is missing---it is not intended there. Usually however,
%% it \emph{is} intended, i.e., the following sequence of
%% lines is wanted:
%% \begin{quotation}\tt\small
%% \expandafter\def\expandafter\{\expandafter{\string{}
%% \expandafter\def\expandafter\}\expandafter{\string}}
%% \obeyspaces\obeylines
%% \cs{RequirePackage}\{longnamefilelist\}
%% \cs{listfiles}[<digit><digit>]
%% \cs{RequirePackage}\{myfilist\}
%% \cs{EmptyFileList}[<read-again-files>]
%% \end{quotation}
%% With v0.2, the last three lines can be replaced by
%% \[|\MaxLengthEmptyList{<digit><digit>}[<read-again-files>|]\]
%% ---``optionally" without \qtd{`[<read-again-files>]'}.
%% This may save the user from worrying about usage
%% with 'myfilist'.
%%
%% == \cs{listfiles} extended ==
%% \label{sec:list}
%% |\listfiles[<number>]| ``orders" a final list of files
%% with infos and optimizes the list's alignment
%% (in plain text output) when the longest base filename
%% consists of <number> characters:
\renewcommand*{\listfiles}[1][\LNFL@chars@set]{%
%% The default parameter `\LNFL@chars@set' is defined in Sec.~\ref{sec:set}.
\let\listfiles\relax
\def\LNFL@chars{#1}%
%% This stores the actual parameter. It is used several times:
%% for preparing the alignment and the final line of stars here
%% and then for aligning each list entry by `\@listfiles'
%% from `\@dofilelist'.
%%
%% \LaTeX's `\@dofilelist' appends a list of ``dummy" tokens `\\'
%% to each filename before `\@listfiles' is run on the filename.
%% \LaTeX's `\@listfiles' is run 8 times, and there are 8 dummies.
%% Dummies not looked at by `\@listfiles' are removed by some
%% ``killing" macro using a token that delimits the dummy list.
%% We use `\relax' tokens as dummies instead. They need not to be removed.
%% And we append <number> dummies. They are stored in a macro `\LNFL@dummies':
\let\LNFL@dummies\@empty
%% `\LNFL@spaces' is used to align the list title ``*file list*"
%% flushleft with the filenames:
\def\LNFL@spaces{ }%
%% We also use more stars than \LaTeX\ below the list. %% space 2012/03/15
%% (However, all of this can also be used for \emph{shorter} names
%% with \emph{less} stars below.)
\def\LNFL@stars{***}%
\count@\LNFL@chars\relax
%% This initializes the loop for adding dummies, title spaces,
%% and stars below the list.
\@whilenum\count@>\z@\do{%
\edef \LNFL@dummies{\LNFL@dummies\relax}%
\ifnum8<\count@
\edef \LNFL@spaces { \LNFL@spaces}%
\fi
\edef \LNFL@stars {*\LNFL@stars}%
\advance\count@\m@ne
}%
%% Our version of `\@listfiles' takes one token ahead at a time
%% and counts the numbes of tokens that have been looked at so far.
%% For each \emph{dummy} found instead of a filename character,
%% (as with \LaTeX) a space is added to `\filename@area'
%% that is used to move the filenames right.
%% As opposed to the \LaTeX\ original version, `\@listfiles' stops
%% being applied after <number> times:
\def\@listfiles##1{%
\ifx##1\relax \edef\filename@area{ \filename@area}\fi
\advance\count@\m@ne
\ifnum\count@>\z@ \expandafter\@listfiles \fi }%
\def\@dofilelist{%
%% In \LaTeX's `\@dofilelist', we first replace the single space
%% starting the title line by `\LNFL@spaces':
\typeout{^^J\LNFL@spaces *File List*}%
\@for\@currname:=\@filelist\do{%
%% This is the loop body adding a list entry line, first like \LaTeX:
\filename@parse\@currname
\edef\reserved@a{%
\filename@base.%
\ifx\filename@ext\relax tex\else\filename@ext\fi}%
\expandafter\let\expandafter\reserved@b
\csname ver@\reserved@a\endcsname
%% We use `\@tempa' for expanding both the filename and the list of dummies
%% in time:
\edef\@tempa{\filename@base\LNFL@dummies}%
\count@\LNFL@chars\relax
\expandafter\expandafter\expandafter\@listfiles\expandafter
\filename@area\@tempa
\typeout{%
\filename@area\reserved@a
\ifx\reserved@b\relax\else
%% I prefer \emph{two} spaces between the columns to four of them:
\space\space %%% \@spaces
\reserved@b\fi}}%
%% The line of stars:
\typeout{ \LNFL@stars^^J}}%
}
%% %% moved up from end 2012/09/30:
%% TODO: 1.~keyval package option avoiding `\listfiles'
%% 2.~measuring longest filename?
%% == Setting Name Length \emph{before} \cs{listfiles} ==
%% \label{sec:set}
%% I first used |\SetLongNameFileListChars{<number>}|
%% for combining the package with 'myfilist' right in place of
%% `\listfiles[<number>]'. Both commands have the same effect
%% on the following `\RequirePackage{myfilist}'.
%% Now that I have realized that I could issue `\listfiles' earlier,
%% `\SetLongNameFileListChars' is rather obsolete---but who knows\,...?
\newcommand*{\SetLongNameFileListChars}{\def\LNFL@chars@set}
%% This macro `\LNFL@chars@set' is used as the default for our new
%% optional parameter for `\listfiles' (Sec.~\ref{sec:list}).
\SetLongNameFileListChars{8}
%% This sets the default value for `\listfiles' to the maximum number
%% of characters in the base filename that
%% \LaTeX\ %% 2012/03/15 %%% `\LaTeX'
%% somewhat expects.
%%
%% == Shorthand for 'myfilist' ==
%% |\MaxLengthEmptyList{<digit><digit>}[<read-again-files>]|
%% as described in Section~\ref{sec:short} (v0.2):
\newcommand*{\MaxLengthEmptyList}[1]{%
\listfiles[#1]\RequirePackage{myfilist}\EmptyFileList}
