| <h2 class="chapter">8 Annotation for <small>GDB</small> Input</h2> |
| |
| <a name="index-annotations-for-prompts"></a> |
| <p>When <small>GDB</small> 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> |
| <p>Different kinds of input each have a different <em>input type</em>. 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: |
| </p> |
| <div class="smallexample"> |
| <pre class="smallexample">^Z^Zpre-prompt |
| ^Z^Zprompt |
| ^Z^Zpost-prompt |
| </pre></div> |
| |
| <p>The input types are |
| </p> |
| <dl compact="compact"> |
| <dd><a name="index-pre_002dprompt"></a> |
| <a name="index-prompt"></a> |
| <a name="index-post_002dprompt"></a> |
| </dd> |
| <dt><code>prompt</code></dt> |
| <dd><p>When <small>GDB</small> is prompting for a command (the main <small>GDB</small> prompt). |
| </p> |
| <a name="index-pre_002dcommands"></a> |
| <a name="index-commands"></a> |
| <a name="index-post_002dcommands"></a> |
| </dd> |
| <dt><code>commands</code></dt> |
| <dd><p>When <small>GDB</small> prompts for a set of commands, like in the <code>commands</code> |
| command. The annotations are repeated for each command which is input. |

| <a name="index-overload_002dchoice"></a> |
| <a name="index-post_002doverload_002dchoice"></a> |
| </dd> |
| <dt><code>overload-choice</code></dt> |
| <dd><p>When <small>GDB</small> wants the user to select between various overloaded functions. |
| </p> |
| <a name="index-pre_002dquery"></a> |
| <a name="index-query"></a> |
| <a name="index-post_002dquery"></a> |
| </dd> |
| <dt><code>query</code></dt> |
| <dd><p>When <small>GDB</small> wants the user to confirm a potentially dangerous operation. |
| </p> |
| <a name="index-pre_002dprompt_002dfor_002dcontinue"></a> |
| <a name="index-prompt_002dfor_002dcontinue"></a> |
| <a name="index-post_002dprompt_002dfor_002dcontinue"></a> |
| </dd> |
| <dt><code>prompt-for-continue</code></dt> |
| <dd><p>When <small>GDB</small> 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. |
