| |
| <p>Sometimes the <code class="code">texinfo-show-structure</code> command produces too much |
| information. Perhaps you want to remind yourself of the overall structure |
| of a Texinfo file, and are overwhelmed by the detailed list produced by |
| <code class="code">texinfo-show-structure</code>. In this case, you can use the <code class="code">occur</code> |
| command directly. To do this, type: |
| </p> |
| <div class="example"> |
| <pre class="example-preformatted"><kbd class="kbd">M-x occur</kbd> |
| </pre></div> |
| |
| <p>and then, when prompted, type a <em class="dfn">regexp</em>, a regular expression for |
| the pattern you want to match. (See <a data-manual="emacs" href="https://www.gnu.org/software/emacs/manual/html_node/emacs/Regexps.html#Regexps">Regular Expressions</a> in <cite class="cite">The GNU Emacs Manual</cite>.) The <code class="code">occur</code> command works from |
| the current location of the cursor in the buffer to the end of the |
| buffer. If you want to run <code class="code">occur</code> on the whole buffer, place |
| the cursor at the beginning of the buffer. |
| </p> |
| <p>For example, to see all the lines that contain the word |
| ‘<samp class="samp">@chapter</samp>’ in them, just type ‘<samp class="samp">@chapter</samp>’. This will |
| produce a list of the chapters. It will also list all the sentences |
| with ‘<samp class="samp">@chapter</samp>’ in the middle of the line. |
| </p> |
| <p>If you want to see only those lines that start with the word |
| ‘<samp class="samp">@chapter</samp>’, type ‘<samp class="samp">^@chapter</samp>’ when prompted by |
| <code class="code">occur</code>. If you want to see all the lines that end with a word |
| or phrase, end the last word with a ‘<samp class="samp">$</samp>’; for example, |
| ‘<samp class="samp">catching mistakes$</samp>’. This can be helpful when you want to see |
| all the nodes that are part of the same chapter or section and |
| therefore have the same ‘Up’ pointer. |
