%%
%% === Alignment Settings ===
%% \label{sec:templates}
%% We use the \ctanpkgref{monofill} package for alignment of plain text:
\RequirePackage{monofill}
%% See its documentation for details.
%%
%% We support three alignment ``fields" according to the terminology of \pkg{monofill}.
%% Their ids are |f-base| for base filenames, |f-ext| for filename extensions,
%% % |f-date| for the revision date,
%% and |f-version| for the revision version id of a file %%% ,
%% % the latter two
%% as read from `\ProvidesFile', `\ProvidesPackage',
%% or `\ProvidesClass' command in the file.
%% Initial settings for them are following.
%% For modifying them, load 'nicefilelist.sty',
%% then type your own settings, then issue `\listfiles'
%% or load 'myfilist.sty'.
\MFfieldtemplate{f-base}{nicefilelist}
\MFfieldtemplate{f-ext}{tex}
\MFfieldtemplate{f-version}{v0.11a}
%% We are not supporting version numbers greater than 9 at present---sorry! (TODO)
%%
%% |\NFLspaceI|, |\NFLspaceII|, and |\NFLspaceIII|
%% determine the space between the four
%% columns for names, dates, versions, and ``captions":
\newcommand*{\NFLspaceI} { \space}
\newcommand*{\NFLspaceII} { \space}
\newcommand*{\NFLspaceIII}{ }
%%
%% === Failure Displays ===
%% \label{sec:failure}
%% |\NFLnodate| is displayed in place of a file date if it seems
%% not to be given (configurable):
\newcommand*{\NFLnodate}{ -- \space-- --}
%% |\NFLnoversion| likewise---however, for alignment,
%% each wanted space must be specified as `\space'
%% (not just a code blank space).
%% It may need adjustment (by `\renewcommand') when
%% `\MFfieldtemplate{f-version}' is modified:
\newcommand*{\NFLnoversion}{\space--}
%% |\NFLnotfound| is for files with wrong or no
%% \cs{Provides.\empty..} command:
\newcommand*{\NFLnotfound}{ * NOT FOUND *}
%%
%% === Safe Tests ===
%% \label{sec:safe}
%% For fairly safe tests, we brief{}ly use an exotic version of `Q'
%% (similarly to \ctanpkgref{ifmptarg}):
\catcode`\Q=7 \let\NFL@criterion=Q \catcode`\Q=11
%% %% 2012/03/27:
%% It appears to me that expandable tests like the ones employed here
%% never are perfectly safe; you only can say that it is safe with a
%% source meeting certain conditions. \ctanpkgref{fifinddo} originally
%% was made for ``plain text," to be read from files without assigning
%% \TeX's special category codes. \emph{Here} we assume that the source
%% (text in \cs{Provides.\empty..} arguments) will never contain such a
%% ``funny `Q'".
%%
%% === Package Option `[r]' ===
%% \label{sec:opt}
%% v0.4 offers package option `[r]' that allows strings with `r'
%% in place of `v', for ``release." `\NFL@v@digit''s definition
%% therefore depends ... we use |\@listfiles| for a ``message"
%% there. For the original restricted functionality, it expands
%% to |\NFL@false|.
\def\@listfiles{\noexpand\NFL@false}
%% Package option `[r]' carries out another test instead.
%% See the accompanying file `SrcFILEs.txt' to see the effect.
%% TODO: update example!?
\DeclareOption{r}{%
\def\@listfiles{%
{\noexpand\NFL@ifx@kbl##1r%
{\noexpand\NFL@digits##2\noexpand\@nnil}%
\noexpand\NFL@false}%
}%
}
\ProcessOptions
%%
%% === Redefining \cs{listfiles} ===
%% Similarly to original \LaTeX, |\listfiles| carries almost everything
%% that is needed for the file list only:
\renewcommand*{\listfiles}{%
\let\listfiles\relax
%% ---this clears memory. Now \LaTeX\ doesn't collect file names for
%% &\listfiles when &\@listfiles is undefined, therefore
% \let\@listfiles\relax
%% % although we don't use it.
%% % (TODO use it in place of some `\NFL@'...?)
%% ... postponed for v0.4 ...
%% \vskip\smallskipamount\noindent
%% |\@dofilelist| is executed by the standard \LaTeX\ `\enddocument'
%% macro or by `\ListInfos' from the \ctanpkgref{myfilist} package.
\def\@dofilelist{%
%% ``Title:"
\typeout{^^J %% trick 2012/03/29 vv
\MFrightinfield{*File Lis}{f-base}t*}%
\@for\@currname:=\@filelist\do{%
%% This starts the loop through the list of files
\filename@parse\@currname
\edef\filename@ext{%

%% Like \LaTeX's &\reserved@b:
\expandafter\let\expandafter\@tempb
\csname ver@\filename@base.\filename@ext\endcsname
%% According to `source2e.pdf', &\filename@area may be a directory.
%% Trying support of this is seems to be a new feature with v0.2---not
%% tested, TODO!
\edef\@tempa{\filename@area\filename@base}%
%% Actually I would like to be able to do even the filename parsing
%% expandably---for all systems, `texsys.cfg'!?? TODO
\typeout{%
%% Now all parsing and checking must be expandable.

}%
%% The line of stars:
\typeout{ %% trick vvv 2012/03/29
\MFrightinfield{********}{f-base}***^^J}%
%% TODO or more stars as with 'longnamefilelist'?
}%
%% This finishes the definition of `\@dofilelist'.
%% % The definitions of macros called from `\@dofilelist' are following.
%% \[|\NFL@make@macro@arg<cmd-1><cmd-2>|\] results in
%% `<cmd-1>{<t-list>}' where <t-list> is the one-step expansion of
%% <cmd-2>:
\def\NFL@make@macro@arg##1##2{\expandafter##1\expandafter{##2}}%
%% |\NFL@space@split{<token-list>}{<spaced>}{<unspaced>}|
%% passes prefix and suffix as arguments to <spaced>
%% if a space token is within <token-list>, otherwise
%% <unspaced> gets the original <token-list> as single
%% argument. The latter is useful here where <token-list>
%% becomes visible only by an &\expandafter.
%% The following construction is discussed more generally
%% in the \ctanpkgref{bitelist} package.
\def\NFL@space@split##1{%
\NFL@return@space@split##1\@nil: \NFL@criterion\@nil\@nil@{##1}}%
%% `\NFL@return@spaces@split' essentially has \emph{three} parameters
%% delimited by ` ', `\@nil', and `\@nil' again.
\def\NFL@return@space@split##1 ##2\@nil##3\@nil@##4##5##6{%
\NFL@ifx@kbl\NFL@criterion{##2}%
%% If #2 is empty, `\NFL@ifx@kbl' (as of v0.3) compares
%% `\NFL@criterion' (criterion indicating ``unspaced") with
%% `\expandafter'. This only happens when the space is the last thing
%% in <token-list>, and `<spaced>' is chosen correctly.

\def\NFL@ifx@kbl##1##2{%
\ifx##1##2\expandafter \@firstoftwo

%% Digit candidates back:

%% If the word is a date, we now have taken 6 of the 8 digits.
%% \[|\NFL@ten@only{<digits>}<digit><digit>Q|\]
%% takes the two remaining and then a thing that should be `Q'
%% in the funny sense of Sec.~\ref{sec:safe}.

\def\NFL@if@digit@code##1##2##3{%
\ifnum`##1##2`##3 \expandafter \@firstoftwo

\def\NFL@false##1\@nil{\@secondoftwo}%
%% |\NFL@true| skips further candidates and dummies and chooses <yes>:
\def\NFL@true##1\@nil{\@firstoftwo}%
%% We don't support version without date, therefore run

%% does not start with a date:
\def\NFL@no@date@version{%
\NFLnodate\NFLspaceII\NFLnoversion@\NFLspaceIII}%
%% |\NFLnoversion@| adds filler to &\NFLnoversion:

%% if <rest> contains a version id. Otherwise ```<word-1>_<rest>'"
%% is considered a ``caption" only.
\def\NFL@maybe@three##1##2{%

%% |\NFL@v@digit{<t1>}{<t2>}{<rest>}| checks whether the first thing
