@cindex compatibility, @sc{gdb/mi} and CLI
@cindex @sc{gdb/mi}, compatibility with CLI
-For the developers convenience CLI commands can be entered directly.
-However, CLI commands that use sequences of commands such @code{source},
-@code{commands} will not work and commands that result in queries such
-as pending breakpoints and quitting once execution has started will
-default to yes.
+For the developers convenience CLI commands can be entered directly,
+but there may be some unexpected behaviour. For example, commands
+that query the user will behave as if the user replied yes, breakpoint
+command lists are not executed and some CLI commands, such as
+@code{if}, @code{when} and @code{define}, prompt for further input with
+@samp{>}, which is not valid MI output.
This feature may be removed at some stage in the future and it is
-recommended that front ends use the @code{-interpreter exec} command.
-@xref{GDB/MI Miscellaneous Commands}.
+recommended that front ends use the @code{-interpreter-exec} command
+(@pxref{-interpreter-exec}).

+For the implementation of a variable debugger window (locals, watched

-@c @subheading -kod-list-object-types
+The two main reasons for that are:

+It will shorten development time (needless to say how important it is

+@end enumerate
-The memory overlay commands are not implemented.
+The original interface was designed to be used by Tcl code, so it was
+slightly changed so it could be used through @sc{gdb/mi}. This section
+describes the @sc{gdb/mi} operations that will be available and gives some
+hints about their use.
-@c @subheading -overlay-auto
+@emph{Note}: In addition to the set of operations described here, we
+expect the @sc{gui} implementation of a variable window to require, at
+least, the following operations:

+@itemize @bullet
+@item @code{-gdb-show} @code{output-radix}

-@c @subheading -overlay-list-overlays
+@subheading Introduction to Variable Objects in @sc{gdb/mi}
-@c @subheading -overlay-map
+@cindex variable objects in @sc{gdb/mi}
+The basic idea behind variable objects is the creation of a named object
+to represent a variable, an expression, a memory location or even a CPU
+register. For each object created, a set of operations is available for
+examining or changing its properties.
-@c @subheading -overlay-off
+Furthermore, complex data types, such as C structures, are represented
+in a tree format. For instance, the @code{struct} type variable is the
+root and the children will represent the struct members. If a child
+is itself of a complex type, it will also have children of its own.
+Appropriate language differences are handled for C, C@t{++} and Java.
-@c @subheading -overlay-on
+When returning the actual values of the objects, this facility allows
+for the individual selection of the display format used in the result
+creation. It can be chosen among: binary, decimal, hexadecimal, octal
+and natural. Natural refers to a default format automatically
+chosen based on the variable type (like decimal for an @code{int}, hex
+for pointers, etc.).
-@c @subheading -overlay-unmap
+The following is the complete set of @sc{gdb/mi} operations defined to
+access this functionality:

+
+This operation creates a variable object, which allows the monitoring of
+a variable, the result of an expression, a memory cell or a CPU
+register.
+The @var{name} parameter is the string by which the object can be
+referenced. It must be unique. If @samp{-} is specified, the varobj
+system will generate a string ``varNNNNNN'' automatically. It will be
+unique provided that one does not specify @var{name} on that format.

-For the implementation of a variable debugger window (locals, watched

-used by @code{Insight}.
+List symbol files.
-The two main reasons for that are:
+@subsubheading @value{GDBN} Command
-@enumerate 1
-@item
-It has been proven in practice (it is already on its second generation).
+The corresponding @value{GDBN} command is @samp{info file} (part of it).
-@item
-It will shorten development time (needless to say how important it is
-now).
-@end enumerate
+@subsubheading Example
+N.A.
-The original interface was designed to be used by Tcl code, so it was
-slightly changed so it could be used through @sc{gdb/mi}. This section
-describes the @sc{gdb/mi} operations that will be available and gives some
-hints about their use.
-@emph{Note}: In addition to the set of operations described here, we
-expect the @sc{gui} implementation of a variable window to require, at
-least, the following operations:
+@subheading The @code{-file-symbol-file} Command

-@itemize @bullet
-@item @code{-gdb-show} @code{output-radix}

-@subheading Introduction to Variable Objects in @sc{gdb/mi}
+@smallexample
+ -file-symbol-file @var{file}
+@end smallexample
-@cindex variable objects in @sc{gdb/mi}
-The basic idea behind variable objects is the creation of a named object
-to represent a variable, an expression, a memory location or even a CPU
-register. For each object created, a set of operations is available for
-examining or changing its properties.
+Read symbol table info from the specified @var{file} argument. When
+used without arguments, clears @value{GDBN}'s symbol table info. No output is
+produced, except for a completion notification.
-Furthermore, complex data types, such as C structures, are represented
-in a tree format. For instance, the @code{struct} type variable is the
-root and the children will represent the struct members. If a child
-is itself of a complex type, it will also have children of its own.
-Appropriate language differences are handled for C, C@t{++} and Java.
+@subsubheading @value{GDBN} Command
-When returning the actual values of the objects, this facility allows
-for the individual selection of the display format used in the result
-creation. It can be chosen among: binary, decimal, hexadecimal, octal
-and natural. Natural refers to a default format automatically
-chosen based on the variable type (like decimal for an @code{int}, hex
-for pointers, etc.).
+The corresponding @value{GDBN} command is @samp{symbol-file}.
-The following is the complete set of @sc{gdb/mi} operations defined to
-access this functionality:
