The paragraph is laid down in a buffer, as it appears, and +isn’t touched further until the end-paragraph marker is processed. +It’s at this point that the paragraph parameters have effect; and it’s +because of this sequence that one often makes mistakes that lead to +the paragraph parameters not doing what one would have hoped (or +expected). +<p/>Consider the following sequence of LaTeX: +<blockquote> +<pre> +{\raggedright % declaration for ragged text +Here's text to be ranged left in our output, +but it's the only such paragraph, so we now +end the group.} + +Here's more that needn't be ragged... +</pre> +</blockquote><p> +TeX will open a group, and impose the ragged-setting parameters within +that group; it will then save a couple of sentences of text and +close the group (thus restoring the previous value of the +parameters that <code>\</code><code>raggedright</code> set). Then TeX encounters a blank +line, which it knows to treat as a <code>\</code><code>par</code> token, so it typesets the +two sentences; but because the enclosing group has now been closed, +the parameter settings have been lost, and the paragraph will be +typeset normally. +<p/>The solution is simple: close the paragraph inside the group, so that +the setting parameters remain in place. An appropriate way of doing +that is to replace the last three lines above with: +<blockquote> +<pre> +end the group.\par} +Here's more that needn't be ragged... +</pre> +</blockquote><p> +In this way, the paragraph is completed while <code>\</code><code>raggedright</code>’s +parameters are still in force within the enclosing group. +<p/>Another alternative is to define an environment that does the +appropriate job for you. For the above example, LaTeX already +defines an appropriate one: +<blockquote> +<pre> +\begin{flushleft} +Here's text to be ranged left... +\end{flushleft} +</pre> +</blockquote><p> +<p/>In fact, there are a number of parameters for which TeX only +maintains one value per paragraph. A tiresome one is the set of upper +case/lower case translations, which (oddly enough) constrains +hyphenation of mutilingual texts. Another that regularly creates +confusion is <a href="FAQ-baselinepar.html"><code>\</code><code>baselineskip</code></a>. +<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=paraparam">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=paraparam</a> +</body> |
