For example, both the -<i>txfonts</i> and <i>amsmath</i> define a command <code>\</code><code>iint</code> -(and <code>\</code><code>iiint</code> and so on); so -<blockquote> -<pre> -... -\usepackage{txfonts} -\usepackage{amsmath} -</pre> -</blockquote><p> -produces a string of error messages of the form: -<blockquote> -<pre> -! LaTeX Error: Command \iint already defined. - Or name \end... illegal, see p.192 of the manual. -</pre> - -</blockquote><p> -As a general rule, things that <i>amsmath</i> defines, it defines -well; however, there is a good case for using the <i>txfonts</i> -version of <code>\</code><code>iint</code> — the associated <i>tx</i> fonts have a -double integral symbol that doesn’t need to be “faked” in the way -<i>amsmath</i> does. In the case that you are loading several -symbol packages, every one of which defines the same symbol, you are -likely to experience the problem in a big way (<code>\</code><code>euro</code> is a common -victim). -<p/>There are similar cases where one package redefines another’s command, -but no error occurs because the redefining package doesn’t use -<code>\</code><code>newcommand</code>. Often, in such a case, you only notice the change -because you assume the definition given by the first package. The -<i>amsmath</i>–<i>txfonts</i> packages are just such a pair; -<i>txfonts</i> doesn’t provoke errors. -<p/>You may deal with the problem by saving and restoring the command. -Macro programmers may care to do this for themselves; for the rest of -us, there’s the package <i>savesym</i>. The sequence: -<blockquote> -<pre> -\usepackage{savesym} -\usepackage{amsmath} -\savesymbol{iint} -\usepackage{txfonts} -\restoresymbol{TXF}{iint} -</pre> -</blockquote><p> -does the job; restoring the <i>amsmath</i> version of the command, -and making the <i>txfonts</i> version of the command available as -<code>\</code><code>TXFiint</code>. -<p/>Documentation of <i>savesym</i> doesn’t amount to much: the only -commands are <code>\</code><code>savesymbol</code> and <code>\</code><code>restoresymbol</code>, as noted above. -<dl> -<dt><tt><i>amsmath.sty</i></tt><dd>Part of <a href="ftp://cam.ctan.org/tex-archive/macros/latex/required/amslatex.zip">macros/latex/required/amslatex</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/latex/required/amslatex.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/latex/required/amslatex/">browse</a>) -<dt><tt><i>savesym.sty</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/savesym/savesym.sty">macros/latex/contrib/savesym/savesym.sty</a> -<dt><tt><i>txfonts.sty</i></tt><dd>Part of <a href="ftp://cam.ctan.org/tex-archive/fonts/txfonts.zip">fonts/txfonts</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/txfonts.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/txfonts/">browse</a>) -</dl> -<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=alreadydef">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=alreadydef</a> -</body> |
