| |
| <p>Sometimes you need to show an example of text in an Emacs buffer. In |
| such examples, the convention is to include the entire contents of the |
| buffer in question between two lines of dashes containing the buffer |
| name. |
| </p> |
| <p>You can use the ‘<samp class="samp">@point{}</samp>’ command to show the location of |
| point in the text in the buffer. (The symbol for point, of course, is |
| not part of the text in the buffer; it indicates the place |
| <em class="emph">between</em> two characters where point is located.) |
| </p> |
| <p>The <code class="code">@point{}</code> command is displayed as ‘<samp class="samp">∗</samp>’, either |
| a pointed star or (when that is not available) the ASCII sequence |
| ‘<samp class="samp">-!-</samp>’. |
| </p> |
| <p>The following example shows the contents of buffer <samp class="file">foo</samp> before |
| and after evaluating a Lisp command to insert the word <code class="code">changed</code>. |
| </p> |
| <div class="example"> |
| <div class="group"><pre class="example-preformatted">---------- Buffer: foo ---------- |
| This is the ∗contents of foo. |
| ---------- Buffer: foo ---------- |
| |
| </pre></div></div> |
| |
| <div class="example"> |
| <div class="group"><pre class="example-preformatted">(insert "changed ") |
| ⇒ nil |
| ---------- Buffer: foo ---------- |
| This is the changed ∗contents of foo. |
| ---------- Buffer: foo ---------- |
| |
| </pre></div></div> |
| |
| <p>In a Texinfo source file, the example is written like this: |
| </p> |
| <div class="example"> |
| <pre class="example-preformatted">@example |
| ---------- Buffer: foo ---------- |
| This is the @point{}contents of foo. |
| ---------- Buffer: foo ---------- |
| |
| (insert "changed ") |
| @result{} nil |
| ---------- Buffer: foo ---------- |
| This is the changed @point{}contents of foo. |
| ---------- Buffer: foo ---------- |
| @end example |
| </pre></div> |
