%% == \cs{newlet} ==                                    %% 2012/10/03
%% |\newlet<cmd><cnd>| is also useful in surrounding files:
\newcommand*{\newlet}[2]{\@ifdefinable#1{\let#1#2}}
%%
%% == Processing ==
%% === Requirement ===
%% We are building on the 'fifinddo' package
%% (using `\protected@edef' for \secref{ligs}):
\RequirePackage{fifinddo}[2011/11/21]
%%
%% === Output File Names ===
%% |\htmakeext| is the extension of the generated file. 
%% Typically it should be `.html', as set here, 
%% but my Atari emulator needs `.htm' 
%% (see `texblog.fdf'):
\newcommand*{\htmakeext}{.html}
%%
%% === General Insertions ===
%% |\CLBrk| is a \emph{code line break} 
%% (also saving subsequent comment mark in macro definitions):
\newcommand*{\CLBrk}{^^J}
%% |\ | is turned into an alias for `\space', 
%% so it inserts a blank space. It even works at line ends, 
%% thanks to the choice of `\endlinechar' in \secref{catcodes}.
\let\ \space
%% %% v0.42:
%% |\ProvidesFile{<file-name>.tex}[<file-info>]| \ is supported 
%% for use with the \CtanPkgRef{morehype}{myfilist} 
%% package  %% TODO \urlpkgfoot!? 2011/02/22
%% to get a list of source file infos. 
%% In generating the \HTML\ file, the file infos are transformed 
%% into an \HTML\ comment. Actually it is 
%% |\BlogProvidesFile| (for the time being, 2011/02/22):
\@ifdefinable\BlogProvidesFile{%
    \def\BlogProvidesFile#1[#2]{%
        <!DOCTYPE html>\CLBrk               %% TODO more!? 2012/09/06
        \comment{ generated from\CLBrk\CLBrk
                  \ \ \ \ \ \ \ \ \ #1, #2,\CLBrk\CLBrk
                  \ \ \ \ \ with blog.sty,
                  \isotoday\ }}} 
\edef\isotoday{%% texblog 2011/11/02, here 2011/11/20
   \the\year-\two@digits{\the\month}-\two@digits{\the\day}}
%% %% changes 2011/02/24:
%% (TODO: customizable style.)---Due to the limitations 
%% of the approach reading the source file
%% line by line, the ``optional argument" `[<file-info>]' 
%% of `\ProvidesFile' must appear in the same line as 
%% the closing brace of its mandatory argument.
%% The feature may require inserting 
%% \[`\let\ProvidesFile\BlogProvidesFile'\] 
%% somewhere, e.g., in `\BlogProcessFile'. 
%%
%% === Category Codes etc. ===
%% \label{sec:catcodes}
%% For a while, line endings swallowed inter-word spaces, 
%% until I found the setting of `\endlinechar' 
%% ('fifinddo''s default is `-1') 
%% in |\BlogCodes|:
\newcommand*{\BlogCodes}{%                              %% 2010/09/07

%% === The Processing Loop ===
%% \[|\BlogProcessFile[<changes>]{<source-file>}|\]
%% %% <- display 2011/11/06
%% ``copies" the \TeX\ source file <source-file> 
%% into the file specified by `\ResultFile'. 
\newcommand*{\BlogProcessFile}[2][]{%                   %% 2011/11/05

%% 'fifinddo' v0.5 allows the following                 %% 2011/11/20

\newcommand*{\BlogProcessFinalFile}{%
    \FinalInputFiletrue\BlogProcessFile}
%% TODO:                                                %% 2011/11/20
%% optionally include `.css' code with \xmltagcode{style}.
%% === \emph{Executing} Source File Code Optionally ===
%% For v0.7,                                            %% 2011/11/05 
%% `\BlogCopyFile' is renamed     `\BlogProcessFile'; and in its code,
%% `\CopyLine'     is replaced by `\BlogProcessLine'. The purpose 
%% of this is supporting 'blogexec.sty' that allows intercepting 
%% certain commands in the line. We provide initial versions of 
%% 'blogexec''s switching commands that allow invoking 'blogexec'
%% ``on the fly": 
\newcommand*{\ProvideBlogExec}{\RequirePackage{blogexec}}
%% \CtanPkgRef{dowith}{dowith.sty} is used in the       %% 2012/01/06
%% present package to reduce package code and documentation space:
\RequirePackage{dowith}
\setdo{\providecommand*#1{\ProvideBlogExec#1}}
\DoDoWithAllOf{\BlogInterceptExecute \BlogInterceptEnvironments
               \BlogInterceptExtra   \BlogInterceptHash        }
%% %% <- Hash 2011/11/08
%% |\BlogCopyLines| switches to the ``copy only" 
%% (``compressing" empty lines) functionality of the original 
%% `\BlogCopyFile':
\newcommand*{\BlogCopyLines}{%
%     \let\BlogProcessLine\CopyLine}
    \def\BlogProcessLine{%          %% 2011/11/21, corr. 2012/03/14:
        \WriteResult{\ProcessInputWith\BlogOutputJob}}}
%% <- This is a preliminary support for ``ligatures"---see 
%% \secref{ligs}. %%% --, not working inside braces. 
%% |\NoBlogLigs| sets the default to mere copying:
\newcommand*{\NoBlogLigs}{\def\BlogOutputJob{LEAVE}}
\NoBlogLigs
%% TODO more from `texblog.fdf' here, problems with `writings.fdf', 
%% see its `makehtml.tex'
%% %% 2011/11/06:
%% % ... and this will be the setting with pure 'blog.sty':
%%
%% `\BlogCopyLines' %% 2011/11/21
%% will be the setting with pure 'blog.sty':
\BlogCopyLines
%% OK, let's not remove |\BlogCopyFile| altogether, rebirth:
\newcommand*{\BlogCopyFile}{\BlogCopyLines\BlogProcessFile}
%% 
%% === ``Ligatures", Package Options ===
%% \label{sec:ligs}
%% With v0.7, we introduce a preliminary method to use the 
%% ``ligatures" `--' and `---' with pure expansion. 
%% At this occasion, we also can support the notation 
%% \code{\dots} for `\dots', as well as arrows 
%% (as in `mdoccorr.cfg'). Note that this is somewhat 
%% \strong{dangerous}, especially the source must not 
%% contain ``explicit" \HTML\ comment, comments must use 
%% 'blog.sty''s `\comment' or the `{commentlines}'
%% environment. Therefore these ``ligatures" must be activated 
%% explicitly by |\UseBlogLigs|: 
\newcommand*{\UseBlogLigs}{\def\BlogOutputJob{BlogLIGs}}
%% In order to work inside braces, the source file better should 
%% be preprocessed in ``plain text mode."
%% (TODO: Use `\ifBlogLigs', and in a group use 
%%        `\ResultFile' for an intermediate `\htmljob.lig'.
%% And TODO: Use `\let\BlogOutputJob'.)
%% On the other hand, the present approach allows switching 
%% while processing with `\EXECUTE'! Also, intercepted commands 
%% could apply the replacements on their arguments---using 
%% |\ParseLigs{<arg>}|:                                 %% 2011/11/27
\newcommand*{\ParseLigs}[1]{\ProcessStringWith{#1}{BlogLIGs}}
%% (`\ProcessStringWith' is from 'fifinddo'.)---The package 
%% 'blogligs.sty' described in \secref{moreligs} does these 
%% things in a more powerful way. You can load it by calling 
%% 'blog.sty''s package option |[ligs]| (v0.8):
\DeclareOption{ligs}{\AtEndOfPackage{\RequirePackage{blogligs}}}
%% 
%% The replacement chain follows (TODO move to `.cfg').
%% As opposed to the file `mdoccorr.cfg' for 'makedoc.sty', 
%% we are dealing with ``normal \TeX" code 
%% (regarding category codes, 'fifinddo.sty' 
%%  as of 2011/11/21 is needed for `\protect').
%% Moreover, space tokens after patterns are already there 
%% and need not be inserted after control sequences.
\FDpseudoTilde
\StartPrependingChain
\PrependExpandableAllReplacer{blog...}{...}{\protect\dots}
\PrependExpandableAllReplacer{blog--}{--}{\protect\endash}
\PrependExpandableAllReplacer{blog---}{---}{\protect\emdash}
%% <- Cf. thin surrounding spaces with 
%% `\enpardash' ('texblog', maybe \meta{hair space} U+200A 
%% instead of thin space), difficult at code line beginnings 
%% or endings and when a paragraph starts with an emdash.
%% I.e., perhaps better don't use it if you want to have 
%% such spaces.---\qtd{`---'} must be replaced before \qtd{`--'}!
\PrependExpandableAllReplacer{blog->}{->}{\protect\to}
\PrependExpandableAllReplacer{blog<-}{<-}{\protect\gets}
%% You also could set `\BlogOutputJob' to a later part of the chain, 
%% or more globally change the following:
\CopyFDconditionFromTo{blog<-}{BlogLIGs}
%% % TODO: Seems to slow down processing by a major part of a second.
%% % Reduce replacements? Maybe do all of this within source file!?
%% The package 'markblog.sty' described in \secref{mark} extends this 
%% to some markup resembling \Wikiref{wiki} editing.
%% This package may be loaded by 'blog.sty''s package option |[mark]| 
%% (v0.8):
\DeclareOption{mark}{\AtEndOfPackage{\RequirePackage{markblog}}}
%% 
%% === \xmltagcode{p} from Empty Line, Package Option ===
%% \label{sec:autopars}
%% As in \TeX\ an empty line starts a new paragraph, 
%% we might ``interpret" an empty source line as 
%% \HTML\ tag \xmltagcode{p} for starting a new paragraph. 
%% Empty source lines following some first empty source 
%% line immediately are ignored 
%% (``compression" of empty lines). 
%% However, this sometimes has unwanted effects 
%% (comment lines TODO),                        %% 2011/11/20
%% so it must be required explicitly by |\BlogAutoPars|, 
%% or by calling the package with option |[autopars]|.
%% In the latter case, it can be turned off by 
%% |\noBlogAutoPars|
\newif\ifBlogAutoPars
\newcommand*{\BlogAutoPars}{\BlogAutoParstrue}
\newcommand*{\noBlogAutoPars}{\BlogAutoParsfalse}
%% `\BlogAutoPars' is issued by package option          %% 2011/11/20
%% |[autopars]|:
\DeclareOption{autopars}{\BlogAutoPars}
\ProcessOptions
%% See \secref{p-br} for other ways of breaking paragraphs.
%%
%% == General \HTML\ Matters ==
%% The following stuff is required for any web page 
%% (or hardly evitable).
%% === General Tagging ===
%% %% $$ -> \[ ... 2011/10/10 el-name -> elt-name 2012/09/14:
%% \[|\TagSurr{<elt-name>}{<attr>}{<content>}|\]
%% (I hoped this way code would be more readable 
%%  than with `\TagSurround' ...)
%% and \[|\SimpleTagSurr{<elt-name>}{<content>}|\]
%% are used to avoid repeating element names <elt-name> in 
%% definitions of \TeX\ macros that refer to ``entire" 
%% elements---as opposed to elements whose content often
%% spans lines (as readable \HTML\ code). 
%% We will handle the latter kind of elements 
%% using \LaTeX's idea of ``environments."
%% `\TagSurr' also inserts specifications of element
%% \textbf{attributes}, 
%% [TODO: 'wiki.sty' syntax would be so nice here]
%% while `\SimpleTagSurr' is for elements used without 
%% specifying attributes. |\STS| is an abbreviation for 
%% `\SimpleTagSurr' that is useful as the `\SimpleTagSurr'
%% function occurs so frequently: 
\newcommand*{\SimpleTagSurr}[2]{<#1>#2</#1>}
\newlet\STS\SimpleTagSurr                           %% 2010/05/23
%% %% 2012/09/08:
%% With the space in `\declareHTMLattrib' as of 2012/08/28, 
%% we remove the space between #1 and #2. 
%% (Doing this by an option may be better TODO; 
%%  any separate attribute definitions must take care of this.)
% \newcommand*{\TagSurr}[3]{<#1#2>#3</#1>}
%% ... undone 2012/11/16, bad with ``direct" use of #2 
%% (with attributes not declared):
\newcommand*{\TagSurr}[3]{<#1 #2>#3</#1>}
%%
%% === Attributes === %%% (General) %%% 
%% Inspired by the common way to use `@' for referring 
%% to element attributes---i.e., `@<attr>' refers to attribute
%% `<attr>'---in \HTML/\acro{XML} documentation, we often use 
%% \[`\@<attr>{<value>}' \qquad 
%%   \mbox{to ``abbreviate"}\qquad  `<attr>="<value>"'\] 
%% within the starting tag of an \HTML\ element.
%% This does not really 
%% make typing easier or improve readability, 
%% it rather saves \TeX's memory by using a single token 
%% for referring to an attribute.
%% This ``abbreviation" is declared by 
%% |\declareHTMLattrib{<attr>}|, even with a check 
%% whether `\@<attr>' has been defined before: 
\newcommand*{\declareHTMLattrib}[1]{%
  \def\reserved@a{@#1}%
  \@ifundefined\reserved@a                   %% \res... 2012/09/06
               {\@namedef{@#1}##1{ #1="##1"}}%% space   2012/08/28
                \@notdefinable}
%% So after `\declareHTMLattrib{<attr>}', `\@<attr>' is a 
%% \TeX\ macro expecting one parameter for the specification. 
%%
%% % |\declareHTMLattribs{{<attr>}<list>}| essentially issues 
%% % \[`\declareHTMLattrib{<attr>}\declareHTMLattribs{<list>}'\]
%% % while `\declareHTMLattribs{}' essentially does nothing---great, 
%% % this is an explanation by recursion!
%% % % \newcommand*{\declareHTMLattribs}{\DoWithAllOf\declareHTMLattrib}
%% A few frequent attributes are declared this way here. 
%% %% 2011/09/27:
%% |@class|, |@id|, |@style|, |@title|, |@lang|, and |@dir|
%% are the ones named on 
%% \wikienref{HTML\#Attributes}{\meta{Wikipedia}}:
\let\@class\relax     %% for tab/arr in latex.ltx
\let\@title\relax     %% for \title in latex.ltx, %% 2011/04/26
\DoWithAllOf\declareHTMLattrib{{class}{id}{style}{title}{lang}{dir}}
%% |@type| is quite frequent too:               %% doc. 2011/09/27
\declareHTMLattrib{type}
%% |@href| is most important for that ``hyper-text:"
\declareHTMLattrib{href} 
%% ... and |@name| (among other uses) is needed for 
%% hyper-text anchors: 
\declareHTMLattrib{name}                        %% 2010/11/06
%% |@content| appears with `\MetaTag' below:    %% 2011/11/05
\declareHTMLattrib{content} 
%% |@bgcolor| is used in tables as well as 
%% for the appearance of the entire page:
\declareHTMLattrib{bgcolor} 
%% 
%% %%% Attributes (Tables) %%%
%% Of course, conflicts may occur, as the form 
%% `\@<ASCII-chars>' of macro names is used for internal 
%% (La)\TeX\ macros. 
%% Indeed, `\@width' that we want to have for the |@width|
%% attribute already ``abbreviates" 
%% \TeX's ``keyword" (\TeX book p.~61) %% 2010/11/27
%% `width' in \LaTeX\ 
%% (for specifying the width of a `\hrule' or `\vrule' from \TeX; 
%%  again just saving \TeX\ tokens rather than for readibility).

\declareHTMLattrib{frame}               %% 2010/07/24
%% \textbf{Another problem} with this namespace idea is that 
%% \emph{either} this reference to attributes cannot be used in 
%% ``author" source files for generating HTML---\emph{or} `@' 
%% cannot be used for ``private" (internal) macros.

%% == Links ==

%% %% doc. fixes + hyperref 2011/10/16:
%% |\hanc{<name>}{<text>}| makes <text> an anchor with 
%% \HTML\ label <name> like \ctanpkgref{hyperref}'s 
%% |\hypertarget{<name>}{<text>}| 
%% (that we actually provide as well, 
%% towards printing from the same source): 
\newcommand*{\hanc}[1]{\TagSurr a{\@name{#1}}}
\newlet\hypertarget\hanc
%% |\hancref{<name>}{<target>}{<text>}| makes <text> an anchor with 
%% \HTML\ label <name> and at the same time a link to <target>: 
\newcommand*{\hancref}[2]{\TagSurr a{\@name{#1} \@href{#2}}}
%% |\href{<name>}{<text>}| makes <text> a link to <name> 
%% (as with 'hyperref'): 
\newcommand*{\href}[1]{\TagSurr a{\@href{#1}}}
%%
%% === Special cases of Basic Link Macros ===
%% |\autanc{<text>}| creates an anchor where <text> is 
%% the text and the internal label at the same time:
\newcommand*{\autanc}[1]{\hanc{#1}{#1}}             %% 2010/07/04
%% |\ancref{<name>}{<text>}| makes <text> a link to 
%% an anchor <name> on the same web page.
%% This is especially useful for a ``table of contents"---a 
%% list of links to sections of the page. 
%% It is just like 'hyperref''s |\hyperlink{<name>}{<text>}|:
\newcommand*{\ancref}[1]{\href{\##1}}
\newlet\hyperlink\ancref
%% |\autref{<text>}| makes <text> a link to an anchor 
%% named <text> itself: 
\newcommand*{\autref}[1]{\ancref{#1}{#1}}           %% 2010/07/04
%%
%% === Italic Variants ===
%% Some of the link macros get ``emphasized" or ``italic" 
%% variants. Originally I used ``emphasized," later I decided 
%% to replace it by ``italic," as I found that I had used 
%% italics for another reason than emphasizing. 
%% E.g., <text> may be \qtd{bug,} and I am not referring to 
%% some bug, but to the Wikipedia article \textit{Bug.}
%% This has been inspired by some Wikipedia typography convention 
%% about referring to titles of books or movies.

%% or more generally with local non-\HTML\ files),
%% so let us have a backbone 
%% |\hnewref{<prot>}{<host-path[#frag]>}{<text>}|

%% === ``Implicit" Attributes and a ``\TeX-like" Interface ===
%% %% <- 2011/11/08 ->
%% After some more experience, much musing, and trying new tricks, 
%% I arrive at the following macros (v0.7). \ 
%% (i)\enspace When a page or a site has many tables that use the same 
%% attribute values, these should not be repeated for the single 
%% tables, rather the values should be invoked by shorthand macros, 
%% and the values should be determined at a single separate place. 
%% We will have |\stdcellpadding|, %%% |\stdtableheadrow|, 
%% |\stdtableheadcolor| and 
%% |\stdtableheadstyle|. \
%% (ii)\enspace As with \TeX, `\cr' should suffice to \emph{close} 
%% a \emph{cell} and a \emph{row}, and then to \emph{open} another 
%% \emph{row} and its first \emph{cell}. And there should be a 
%% single command to close a cell within a row and open a next one.
%%
%% We use `\providecommand' so the user can determine the values 
%% in a file for 'blog' where 'blogexec' is loaded later. 
%% |\stdcellpadding| should correspond to the \CSS\ settings, 
%% the value of `6' you find here is just what I used recently.
\providecommand*{\stdcellpadding}{6}
%% For |\stdtableheadcolor|, I provide a 
%% % ``web-safe"                            %% very wrong 2012/05/13
%% gray, `#EEEEEE', that the German Wikipedia uses for articles about 
%% \Wikienref{networking protocol}s
%% (unfortunately, it doesn't have a 
%% \wikienref{Web colors\#X11_color_names}{%
%% \CSS-3}\wikienref{X11 color names}{X11} color name):
\providecommand*{\stdtableheadcolor}{\#EEEEEE}
%% |\stdtableheadstyle| demands a boldface font. 
%% In general, it is used for the `@style' attribute:
\providecommand*{\stdtableheadstyle}{font-weight:bold}
%% |\begin{stdallrulestable}| starts an `{allrulestable}'
%% environment with ``standard" cell padding and empty width 
%% attribute, then opens a ``standard" row element 
%% with a ``standard" comment as well as a cell:
\newenvironment{stdallrulestable}{%
    \allrulestable{\stdcellpadding}{}\CLBrk
      \TableRow{standard all-rules table}%
               {\@bgcolor{\stdtableheadcolor}
                \@style{\stdtableheadstyle}}\CLBrk
        \indentii\StartTd
%% `\end{stdallrulestable}' will provide closing of a cell
%% and a row, including a code cosmetic:
    }{\indenti\endTd\CLBrk\endTableRow\CLBrk
    \endallrulestable}
%% |\endcell| closes a cell and opens a new one. The idea behind 
%% this is that an active character will invoke it. The name is 
%% inspired by `\endgraf' and `\endline' from Plain \TeX\ and 
%% \LaTeX\ (`\newcommand' does not work with `\end'\code{\dots}):
\def\endcell{\endTd\StartTd}
%% Plain \TeX's and \LaTeX's |\cr| and |\endline| are redefined 
%% for closing and opening rows and cells, including code cosmetic:
\renewcommand*{\cr}{\indentii\endTd\CLBrk\indenti\endtr\CLBrk
                    \indenti\startTR\CLBrk\indentii\StartTd}
\let\endline\cr
%% |\startTR| is a hook defaulting to `\starttr':               %% 2012/08/23
\newlet\startTR\starttr
%% 
%% === Filling a Row with Dummy Cells ===
%% These macros were made, e.g., for imitating a program window 
%% with a title bar (spanning someting more complex below), 
%% perhaps also for a Gantt chart. 
%% |\FillRow{<span>}{<attributes>}| produces a cell without text, 
%% spanning <span> columns, with additional attributes <attributes>. 
%% %% Generalization 2010/06/28:
%% % \newcommand*{\FillRow}[2]{%             %% broke line 2011/01/24
%% %                   \indentiii\TagSurr{td}{\@colspan{#1} #2}{}} 
%% %% <- 2010/07/18 ->
\newcommand*{\FillRow}[2]{\indentiii\startTd{\@colspan{#1} #2}\endTd}
%% |\fillrow{<span>}| instead only uses the `@colspan' attribute:
\newcommand*{\fillrow}[1]{\FillRow{#1}{}}
%% |\fillrowcolor{<span>}{<color>}| just uses the `@colspan'
%% and the `@bgcolor' attributes:
\newcommand*{\fillrowcolor}[2]{\FillRow{#1}{\@bgcolor{#2}}}
%% === Skipping Tricks ===
%% %% 2011/10/13
%% |\HVspace{<text>}{<width>}{<height>}| may change, 
%% needed for 'blogdot.sty' but also for |\vspace{<height>}|
%% with 'texblog'. It is now here so I will be careful 
%% when I want to change something. \xmltagcode{tbody}
%% improved the function of `\HVspace' constructions 
%% as link text with 'blogdot.sty'.
