% Math comma activation is done only after the preamble has
% been completed, that is after the |\begin{document}| statement has been
% completely executed. Now we must give a definition to the active comma:
+% probably it is not necessary to pass through in intermediate robust command, but certainly it is not wrong to do it.
% \begin{macrocode}

+{\catcode `,=\active \gdef,{\it@comma@def}}%
+% \end{macrocode}
+% The real work shall be performed by |\it@comma@def|. In facts the
+% above macro stores the token that immediately follows |\@math@comma|
+% into a temporary control sequence that behaves as an implicit character
+% if that token is a single character, even a space, or behaves as
+% an alias of a control sequence otherwise.
+%
+% Is is important to remark that |\@math@comma| must be a command that
+% does not require arguments; this makes it robust when it is followed
+% by other characters that may play special r\^oles within the arguments
+% of other macros or environments. Matter of fact the first version 1.3
+% of this file in version 1.3 did accept an argument; and the result was
+% that the active comma would ``eat up'' the |&| in vertical math
+% alignments and very hasty problem took place, especially within the
+% |amsmath| defined ones. This macro |\@math@comma| without arguments
+% does not do any harm to the AMS environments and the actual intelligent
+% comma work shall be executed by other macros.
+
+% So first we test if the comma must act intelligently; if the counter
+% |\Virgola| contains zero, we assume that the comma must always perform
+% as a punctuation mark; but if we want to distinguish if it must behave
+% as a decimal separator, we have to perform more delicate tests; this
+% latter task is demanded to another macro with arguments |\@math@@comma|.

+% In particular this macro must test if the argument has category
+% code 12, that is ``other character'', not a letter, nor other

+% to test if a token is a digit, is to test its ASCII code against
+% the ASCII codes of `0' (zero) and 9.
% The typesetting engines give the backtick, |`|, the property that

+% the |\@math@@comma| macro which is not that simple, although the testing
% macros have clear meanings:
% \begin{macrocode}
-\AtEndOfPackage{%
-\AtEndPreamble{%
-\gdef\m@thcomma#1{%
-\ifnumequal{\Virgola}{\z@}{\virgola#1}{%
- \unless\ifcat\noexpand\let@token*%
- \virgola

- {\virgoladecimale}%
- }%
- }{\virgola}%
- \fi#1}}%
-}}
+ {\virgoladecimale}}}{\virgola}#1}
+% \end{macrocode}
+% Notice that the argument |#1| is first changed to a string of category
+% code 12 characters by means of the command |\string|; then |\@gobble|
+% gobbles the first character in the listIf it was a single character
+% the list remains empty, while int it was a control sequence, the
+% backslash get stripped off. Then |ifcsundef| tests if the string is
+% defined as a control sequence; of course it it has to check an empty
+% string, that turns to be undefined, so we are facing a single character,
+% while if the original string was a control sequence the tests turns
+% out to be false. The particular testing macro returns the correct
+% result |true| or |false| whiteout giving a false negative if the
+% string was undefined, as |\ifcsname...\endcsname| would do in the
+% same circumstances. In any case if the argument was a control sequence,
+% the comma whould be a punctuation one, while if it was a single
+% character, its ASCII code is testd to be in the range |`0--`9| and
+% it it's actually in this range the comma has to be a decimal separator.
+%
+% Now the last two macro definitions rely on service macros that are
+% provided by the |etoolbox| package, that shall be read at most at the
+% end of the |babel| package processing; therefore only at the end point
+% we can delay the code at ``end preamble'' time, since only at that time
+% it will be known if the main language is English, or any other one.
+% This is why we have to perform such a baroque definition as the
+% following one:

+% This intelligent comma definition is pretty intelligent, but it requires
+% some kind of information from the context; this context does not
+% give enough bits of information to this `intelligence' in just one case:
% when the comma plays the r\^ole of a serial separator in expressions
% such as $i=1, 2, 3,\dots,\infty$, entered as
% \verb*?$i=1, 2, 3,\dots,\infty$?. In this case and only in this
-% case the comma must be followed by an explicit space, otherwise
-% the macro takes the following non blank token as a digit, and
-% actually it is a digit, and uses the decimal comma instead, which
+% case the comma must be followed by an explicit space; should this space
+% be absent the macro takes the following non blank token as a digit,
+% and since it actually is a digit, it would use the decimal comma, which
% would be wrong. The control sequences |\dots| and |\infty| are
% tested to see if they are undefined, and since they are defined, the macro
% inserts a punctuation mark, instead of a decimal separator.
