25.3 Annotation for No value for GDBN Input

When No value for GDBN 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 No value for GDBN is prompting for a command (the main No value for GDBN prompt).

commands

When No value for GDBN prompts for a set of commands, like in the commands command. The annotations are repeated for each command which is input.

overload-choice

When No value for GDBN wants the user to select between various overloaded functions.

query

When No value for GDBN wants the user to confirm a potentially dangerous operation.

prompt-for-continue

When No value for GDBN 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.
