@chapter Command Interpreters
@cindex command interpreters
@value{GDBN} supports multiple command interpreters, and some command
infrastructure to allow users or user interface writers to switch
between interpreters or run commands in other interpreters.
@value{GDBN} currently supports two command interpreters, the console
interpreter (sometimes called the command-line interpreter or @sc{cli})
and the machine interface interpreter (or @sc{gdb/mi}). This manual
describes both of these interfaces in great detail.
By default, @value{GDBN} will start with the console interpreter.
However, the user may choose to start @value{GDBN} with another
interpreter by specifying the @option{-i} or @option{--interpreter}
startup options. Defined interpreters include:
@table @code
@item console
@cindex console interpreter
The traditional console or command-line interpreter. This is the most often
used interpreter with @value{GDBN}. With no interpreter specified at runtime,
@value{GDBN} will use this interpreter.
@item mi
@cindex mi interpreter
The newest @sc{gdb/mi} interface (currently @code{mi2}). Used primarily
by programs wishing to use @value{GDBN} as a backend for a debugger GUI
or an IDE. For more information, see @ref{GDB/MI, ,The @sc{gdb/mi}
Interface}.
@item mi2
@cindex mi2 interpreter
The current @sc{gdb/mi} interface.
@item mi1
@cindex mi1 interpreter
The @sc{gdb/mi} interface included in @value{GDBN} 5.1, 5.2, and 5.3.
@end table
@cindex invoke another interpreter
The interpreter being used by @value{GDBN} may not be dynamically
switched at runtime. Although possible, this could lead to a very
precarious situation. Consider an IDE using @sc{gdb/mi}. If a user
enters the command "interpreter-set console" in a console view,
@value{GDBN} would switch to using the console interpreter, rendering
the IDE inoperable!
@kindex interpreter-exec
Although you may only choose a single interpreter at startup, you may execute
commands in any interpreter from the current interpreter using the appropriate
command. If you are running the console interpreter, simply use the
@code{interpreter-exec} command:
@smallexample
interpreter-exec mi "-data-list-register-names"
@end smallexample
@sc{gdb/mi} has a similar command, although it is only available in versions of
@value{GDBN} which support @sc{gdb/mi} version 2 (or greater).
