| <h3 class="section">28.3 Annotation for <span class="sc">gdb</span> Input</h3> |
| |
| <p><a name="index-annotations-for-prompts-2135"></a>When <span class="sc">gdb</span> prompts for input, it annotates this fact so it is possible |
| to know when to send output, when the output from a given command is |
| over, etc. |
| |
| <p>Different kinds of input each have a different <dfn>input type</dfn>. Each |
| input type has three annotations: a <code>pre-</code> annotation, which |
| denotes the beginning of any prompt which is being output, a plain |
| annotation, which denotes the end of the prompt, and then a <code>post-</code> |
| annotation which denotes the end of any echo which may (or may not) be |
| associated with the input. For example, the <code>prompt</code> input type |
| features the following annotations: |
| |
| <pre class="smallexample"> ^Z^Zpre-prompt |
| ^Z^Zprompt |
| ^Z^Zpost-prompt |
| </pre> |
| <p>The input types are |

| <a name="index-prompt-annotation-2137"></a> |
| <a name="index-post_002dprompt-annotation-2138"></a> |
| <dl><dt><code>prompt</code><dd>When <span class="sc">gdb</span> is prompting for a command (the main <span class="sc">gdb</span> prompt). |
| |
| <p><a name="index-pre_002dcommands-annotation-2139"></a><a name="index-commands-annotation-2140"></a><a name="index-post_002dcommands-annotation-2141"></a><br><dt><code>commands</code><dd>When <span class="sc">gdb</span> prompts for a set of commands, like in the <code>commands</code> |
| command. The annotations are repeated for each command which is input. |
| |
| <p><a name="index-pre_002doverload_002dchoice-annotation-2142"></a><a name="index-overload_002dchoice-annotation-2143"></a><a name="index-post_002doverload_002dchoice-annotation-2144"></a><br><dt><code>overload-choice</code><dd>When <span class="sc">gdb</span> wants the user to select between various overloaded functions. |
| |
| <p><a name="index-pre_002dquery-annotation-2145"></a><a name="index-query-annotation-2146"></a><a name="index-post_002dquery-annotation-2147"></a><br><dt><code>query</code><dd>When <span class="sc">gdb</span> wants the user to confirm a potentially dangerous operation. |
| |
| <p><a name="index-pre_002dprompt_002dfor_002dcontinue-annotation-2148"></a><a name="index-prompt_002dfor_002dcontinue-annotation-2149"></a><a name="index-post_002dprompt_002dfor_002dcontinue-annotation-2150"></a><br><dt><code>prompt-for-continue</code><dd>When <span class="sc">gdb</span> is asking the user to press return to continue. Note: Don't |
| expect this to work well; instead use <code>set height 0</code> to disable |
| prompting. This is because the counting of lines is buggy in the |
| presence of annotations. |
