However, comparing to |\def| +% the syntax is limited because we cannot use delimited arguments in such a command. +% The advantage of |\newcommand| (apart the optional argument\footnote{optional arguments are +% implemented in a much flexible way by \xpackage{xargs} by Manuel P\'egouri\'e-Gonnard.}) +% is that the control sequence is first checked for availability (its meaning ought to be +% |undefined| or |\relax| before the definition). +% +% \xpackage{etoolbox} enhance this matter allowing to define |\newrobustcmd| and |\renewrobustcmd|. +% +% Moreover, \LaTeX{} does not provide an automatic check of control sequences when defining +% tokens (|\newtoks|), dimensions (|\newdimen|), skips (|\newskip|), etc. etc. + +% The only exceptions are:§ +% \begin{itemize}\itemsep=0pt +% \item |\newlength| \\ +% but there is no |\renewlength| command... because +% the name |\renewlength| sounds bad: it would have meant \textit{``I know the control sequence I wish +% to define as a length has been defined before, as a macro may be, or a box or a token or +% whatever, and I wish to redefine this control sequence to be a length (\textup{ie} a skip)}. +% So it doesn't really make sense... +% \item |\newcounter| \\ +% but |\newcounter{name}| does not define |name| but |\c@name| instead, as a counter. +% \item |\newsavebox| +% \item |\newfont| +% \end{itemize}\restoreparskip +% +% \bfseries All those |\new|\Repeat{3}{\textasteriskcentered}\ stuff define control sequences globally, +% \emph{excepting} |\newfont|. The reason could to be found in the background\footnote{in fact, a new font +% is defined as a control sequence, just like a macro, whereas skips, dimens, tokens etc. are numbered +% and then, defining a new one require an allocation.}. +% +% \mdseries +% But it's a matter of fact : \emph{fonts} are local to \LaTeX{} while \emph{length} (\emph{ie.\,skips}) +% are global... +% +% Thank to the \xpackage{etex} package that provides a method for the local allocation of new quantity +% \xpackage{ltxnew} puts the state of the affairs in a better order. \xpackage{ltxnew} provides a way +% to define new control sequences, or redefine them, just by +% beginning the definition with a (expandable) prefix : |\new| or |\renew|. +% +% \subsection{What \cs{new} means...} +% +% Such a short and easy word as \texttt{new} ought to be defined ! +% +% \bfseries \CS{new} means:§\mdseries +% \begin{itemize}[label=--,topsep=0pt,itemsep=0pt] +% \item Check if the control sequence to define is available (\emph{ie} means |undefined| or |\relax|) +% \item If that's OK: go on (with a side effect if the package \xpackage{tracing} is loaded) +% \item If not : throw an error, and if in |scrollmode| or |nonstopmode| or |batchmode| do not overwrite +% the last meaning. +% \end{itemize} +% +% That is really what means |\new|. No more, no less. +% +% \subsection{What \cs{renew} means} +% +% \bfseries \CS{renew} means:§\mdseries +% \begin{itemize}[label=--,topsep=0pt,itemsep=0pt] +% \item Check if the control sequence to redefine already has a meaning (different from |undefined| and also from |\relax|) +% \item If that's OK : go on (with a side effect if the package \xpackage{tracing} is loaded) +% \item If not : throw an error.
