Sadly, in the case of complex macro packages such -as LaTeX, the underlying TeX problem may be superficially -difficult to relate to the actual problem in the “higher-level” -macros. Many LaTeX-detected problems manifest themselves as -‘generic’ errors, with error text provided by LaTeX itself (or by a -LaTeX class or package). -<p/>The context of the error is a stylised representation of what TeX -was doing at the point that it detected the error. As noted in -<a href="FAQ-erroradvice.html">approaching errors</a>, a macro package -can tell TeX how much context to display, and the user may need to -undo what the package has done. Each line of context is split at the -point of the error; if the error <em>actually</em> occurred in a macro -called from the present line, the break is at the point of the call. -(If the called object is defined with arguments, the “point of call” -is after all the arguments have been scanned.) For example: -<pre> -\blah and so on -</pre> -produces the error report -<pre> -! Undefined control sequence. -l.4 \blah - and so on -</pre> -while: -<pre> -\newcommand{\blah}[1]{\bleah #1} -\blah{to you}, folks -</pre> -produces the error report -<pre> -! Undefined control sequence. -\blah #1->\bleah - #1 -l.5 \blah{to you} - , folks -</pre> -If the argument itself is in error, we will see things such as -<pre> -\newcommand{\blah}[1]{#1 to you} -\blah{\bleah}, folks -</pre> -producing -<pre> -! Undefined control sequence. -<argument> \bleah - -l.5 \blah{\bleah} - , folks -</pre> -<p/>The prompt accepts single-character commands: the list of what’s -available may be had by typing <code>?</code>. One immediately valuable -command is <code>h</code>, which gives you an expansion of TeXs original -précis message, sometimes accompanied by a hint on what to do to -work round the problem in the short term. If you simply type ‘return’ -(or whatever else your system uses to signal the end of a line) at the -prompt, TeX will attempt to carry on (often with rather little -success). -<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=errstruct">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=errstruct</a> -</body> |
