27.6. Annotation for gdb Input
When gdb 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.
Different kinds of input each have a different input type. Each
input type has three annotations: a pre- 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 post-
annotation which denotes the end of any echo which may (or may not) be
associated with the input. For example, the prompt input type
features the following annotations:
^Z^Zpre-prompt
^Z^Zprompt
^Z^Zpost-prompt |
The input types are
- prompt
When gdb is prompting for a command (the main gdb prompt).
- commands
When gdb prompts for a set of commands, like in the commands
command. The annotations are repeated for each command which is input.
- overload-choice
When gdb wants the user to select between various overloaded functions.
- query
When gdb wants the user to confirm a potentially dangerous operation.
- prompt-for-continue
When gdb is asking the user to press return to continue. Note: Don't
expect this to work well; instead use set height 0 to disable
prompting. This is because the counting of lines is buggy in the
presence of annotations.
