This module provides a method for prompt value-substitution.
substitute_prompt (string)
Return string with escape sequences substituted by values. Some escape sequences take arguments. You can specify arguments inside “{}” immediately following the escape sequence.
The escape sequences you can pass to this function are:
\\
Substitute a backslash.
\e
Substitute an ESC character.
\f
Substitute the selected frame; an argument names a frame parameter.
\n
Substitute a newline.
\p
Substitute a parameter’s value; the argument names the parameter.
\r
Substitute a carriage return.
\t
Substitute the selected thread; an argument names a thread parameter.
\v
Substitute the version of GDB.
\w
Substitute the current working directory.
\[
Begin a sequence of non-printing characters. These sequences are typically used with the ESC character, and are not counted in the string length. Example: “\[\e[0;34m\](gdb)\[\e[0m\]” will return a blue-colored “(gdb)” prompt where the length is five.
\]
End a sequence of non-printing characters.
For example:
substitute_prompt (``frame: \f,
print arguments: \p{print frame-arguments}'')
will return the string:
"frame: main, print arguments: scalars"
