That +has the side effect that multiple actual accents can be built +as well. +\item Putting them below the main symbol instead of above. +\end{itemize} + +That is done so that the faked accents behave in quite similar fashion +to actual accents do; i.e., the skew of the letter is taken into +account (compare $\accentset{\ast}{d}$ with +$\accentset{\ast}{h}$) and the sub and superscripts attached to +it aren't misplaced (look carefully at $\accentset{\star}{f}_1^1$). + +Release 1.1 included a few new features, some of them following +suggestions by Donald Arseneau. In particular, the |\underaccent| +command has been fully reimplemented for the slant to be taken into +account and the ``accent'' to be placed below the symbol can be +anyone, not only real accents. This release just makes it compatible +with \textsf{amsmath} 2 with a quick fix. + +\begin{decl} +|\DeclareMathAccent| +\end{decl} + +This \LaTeXe{} command is reimplemented so that newly defined accents +will incorporate the features of this package. The standard accents +are automatically redefined, including |\mathring| if you are using +one of the latest \LaTeX{} releases. However, both |\widetilde| and +|\widehat| remains untouched. If you are using a non standard +math encoding, the accents following the standard encoding names are +rightly redefined, but new accents are not converted because +\textsf{accents} is not aware of its existence. + +See |fntguide.tex| in the \LaTeX{} standard distribution for a discussion on + |\DeclareMathAccent|. + +\begin{decl} +|\ring{<symbol>}| +\end{decl} + +The accent in $\ring{x}$, which was available in this package (and +in fact in many others) before +the |\mathring| command was added to the \LaTeX{} kernel. + +\begin{decl} +|\accentset{<accent>}{<symbol>}| +\end{decl} + +Builds a faked accent, as for instance +\begin{sample} +|\accentset{\star}{d}| \> $\accentset{\star}{d}$\\ +|\accentset{\diamond}{h}| \> $\accentset{\diamond}{h}$\\ +|\tilde{\accentset{\circ}{\phi}}| \> + $\tilde{\accentset{\circ}{\phi}}$ +\end{sample} +The |<accent>| is always in |\scriptscriptmode|; hence, using +|\accentset| in scripts won't give the desired result. Of course, +if you use some faked accent many times, you can define: +\begin{verbatim} +\newcommand\starred[1]{\accentset{\star}{#1}} +\end{verbatim} +and |\starred| will become an accent, like |\hat|, |\tilde|, etc. + +\begin{decl} +|\dddot \ddddot| +\end{decl} + +Two prefabricated faked accents: $\dddot{f}$ and $\ddddot{f}$. + +\begin{decl} +|\underaccent{<accent>}{<symbol>}| +\end{decl} + +This command puts the |<accent>| under the |<symbol>|. Both real +and faked accents are allowed. For instance, +\begin{sample} +|\underaccent{\hat}{x}| \> $\underaccent{\hat}{x}$\\ +|\underaccent{\bar}{\gamma}| \> $\underaccent{\bar}{\gamma}$\\ +|\underaccent{\triangleright}{q}| \> + $\underaccent{\triangleright}{q}$\\ +|\underaccent{\tilde}{\mathcal{A}}| \> + $\underaccent{\tilde}{\mathcal{A}}$ +\end{sample} + +Many people likes using the wider version of the tilde accent as +printed by the |\widetilde| command, i.e., $\widetilde{A}$ instead of +$\tilde{A}$. I find that aesthetically questionable, but anyway it +can be used under the symbol as well. Since |\widetilde| remains +untouched, you should define: +\begin{verbatim} +\DeclareMathAccent{\wtilde}{\mathord}{largesymbols}{"65} +\end{verbatim} +and write |\underaccent{\wtilde}{V}|, say (giving +$\underaccent{\wtilde}{V}$). You may build an accent with +|\sim|, too. (The value for a wide hat is |"62|) + +Sadly, \TeX{} lacks of a mechanism to place underaccents similar to +that used in accents. Letters have a large variety of shapes and +finding an automatic adjusting is practically impossible. Compare for +instance the following letters: +\begingroup +\def\\{\underaccent{\bar}}% +$\\V$, $\\Q$, $\\p$, $\\q$, $\\f$, +$\\\beta$, $\\\gamma$, $\\{\mathcal{F}}$, $\\{\mathcal{A}}$ +\endgroup +and you wil understand the difficulties. + +\begin{decl} +|\undertilde{<symbols>}| +\end{decl} + +This is the ``under'' version of |\widetilde| and like the latter is intended for constructions +involving several symbols. For instance: +\begin{sample} +|\undertilde{CV}| \> $\undertilde{CV}$ +\end{sample} +Note that in this case no correction is made in the placement of the tilde. + +\begin{decl} +|nonscript single| +\end{decl} + +These package options are intended mainly for speeding up the +typesetting of document. The algorithm used here is recursive and +very slow; although in fast processors that is not felt, in slow +system that could be very annoying. + +\begin{description} +\item[single] If you are interested only in |\accentset|. + Accents are not reimplemented. +\item[nonscript] If you intend to use multiple accents in + text and display modes only. +\end{description} + +Macros are speeded up dramaticaly with both options; if your system is slow, +I commend using them in drafts and removing them for the final print. + +Finally, some remarks: +\begin{itemize} +\item The package does not provides alternative accents for fonts + lacking them. If you want an accented |\mathcal| letter you had to + write |\hat{\hat{\mathcal{A}}}| ($\hat{\hat{\mathcal{A}}}$). +\item |\mathbf{\hat{\hat h}}| gets the bold accent; + |\hat{\hat{\mathbf{h}}}| not. +\item The symbol in |\accentset| must be a single symbol. +\item If you use \textsf{accents} with \textsf{amsmath} 2, you must +load \textsf{accents} after. Note that \textsf{amsmath} could redefine +some accents; in particular, if you experience problems with |\vec| +and you are using the standard math encodings, define: +\begin{verbatim} +\let\vec\relax +\DeclareMathAccent{\vec}{\mathord}{letters}{"7E} +\end{verbatim} +\end{itemize} + +\end{document} + |
