@node Parameters In Guile
|
||||
@subsubsection Parameters In Guile
|
||||
|
||||
@cindex parameters in guile
|
||||
@cindex guile parameters
|
||||
@tindex Parameter
|
||||
You can implement new @value{GDBN} @dfn{parameters} using Guile
|
||||
@footnote{Note that @value{GDBN} parameters must not be confused with
|
||||
Guile’s parameter objects (@pxref{Parameters,,, guile, GNU Guile
|
||||
Reference Manual}).}.
|
||||
|
||||
There are many parameters that already exist and can be set in
|
||||
@value{GDBN}. Two examples are: @code{set follow-fork} and
|
||||
@code{set charset}. Setting these parameters influences certain
|
||||
behavior in @value{GDBN}. Similarly, you can define parameters that
|
||||
can be used to influence behavior in custom Guile scripts and commands.
|
||||
|
||||
A new parameter is defined with the @code{make-parameter} Guile function,
|
||||
and added to @value{GDBN} with the @code{register-parameter!} Guile function.
|
||||
This two-step approach is taken to separate out the side-effect of adding
|
||||
the parameter to @value{GDBN} from @code{make-parameter}.
|
||||
|
||||
Parameters are exposed to the user via the @code{set} and
|
||||
@code{show} commands. @xref{Help}.
|
||||
|
||||
@c TODO line length
|
||||
@deffn {Scheme Procedure} (make-parameter name @r{[}#:command-class command-class@r{]} @r{[}#:parameter-type parameter-type{]} @r{[}#:enum-list enum-list@r{]} @r{[}#:set-func set-func{]} @r{[}#:show-func show-func{]} @r{[}#:doc doc{]} @r{[}#:set-doc set-doc{]} @r{[}#:show-doc show-doc{]} @r{[}#:initial-value initial-value{]})
|
||||
|
||||
The argument @var{name} is the name of the new parameter. If @var{name}
|
||||
consists of multiple words, then the initial words are looked for as prefix
|
||||
parameters. An example of this can be illustrated with the
|
||||
@code{set print} set of parameters. If @var{name} is
|
||||
@code{print foo}, then @code{print} will be searched as the prefix
|
||||
parameter. In this case the parameter can subsequently be accessed in
|
||||
@value{GDBN} as @code{set print foo}.
|
||||
If @var{name} consists of multiple words, and no prefix parameter group
|
||||
can be found, an exception is raised.
|
||||
|
||||
The result is the @code{<gdb:parameter>} object representing the parameter.
|
||||
The parameter is not usable until it has been registered with @value{GDBN}
|
||||
with @code{register-parameter!}.
|
||||
|
||||
The rest of the arguments are optional.
|
||||
|
||||
The argument @var{command-class} should be one of the @samp{COMMAND_} constants
|
||||
(@pxref{Commands In Guile}). This argument tells @value{GDBN} how to
|
||||
categorize the new parameter in the help system.
|
||||
The default is @code{COMMAND_NONE}.
|
||||
|
||||
The argument @var{parameter-type} should be one of the @samp{PARAM_} constants
|
||||
defined below. This argument tells @value{GDBN} the type of the new
|
||||
parameter; this information is used for input validation and
|
||||
completion. The default is @code{PARAM_BOOLEAN}.
|
||||
|
||||
If @var{parameter-type} is @code{PARAM_ENUM}, then
|
||||
@var{enum-list} must be a list of strings. These strings
|
||||
represent the possible values for the parameter.
|
||||
|
||||
If @var{parameter-type} is not @code{PARAM_ENUM}, then the presence
|
||||
of @var{enum-list} will cause an exception to be thrown.
|
||||
|
||||
The argument @var{set-func} is a function of one argument: @var{self} which
|
||||
is the @code{<gdb:parameter>} object representing the parameter.
|
||||
@value{GDBN} will call this function when a @var{parameter}'s value has
|
||||
been changed via the @code{set} API (for example, @kbd{set foo off}).
|
||||
The value of the parameter has already been set to the new value.
|
||||
This function must return a string to be displayed to the user.
|
||||
@value{GDBN} will add a trailing newline if the string is non-empty.
|
||||
@value{GDBN} generally doesn't print anything when a parameter is set,
|
||||
thus typically this function should return @samp{""}.
|
||||
A non-empty string result should typically be used for displaying warnings
|
||||
and errors.
|
||||
|
||||
The argument @var{show-func} is a function of two arguments: @var{self} which
|
||||
is the @code{<gdb:parameter>} object representing the parameter, and
|
||||
@var{svalue} which is the string representation of the current value.
|
||||
@value{GDBN} will call this function when a @var{parameter}'s
|
||||
@code{show} API has been invoked (for example, @kbd{show foo}).
|
||||
This function must return a string, and will be displayed to the user.
|
||||
@value{GDBN} will add a trailing newline.
|
||||
|
||||
The argument @var{doc} is the help text for the new parameter.
|
||||
If there is no documentation string, a default value is used.
|
||||
|
||||
The argument @var{set-doc} is the help text for this parameter's
|
||||
@code{set} command.
|
||||
|
||||
The argument @var{show-doc} is the help text for this parameter's
|
||||
@code{show} command.
|
||||
|
||||
The argument @var{initial-value} specifies the initial value of the parameter.
|
||||
If it is a function, it takes one parameter, the @code{<gdb:parameter>}
|
||||
object and its result is used as the initial value of the parameter.
|
||||
The initial value must be valid for the parameter type,
|
||||
otherwise an exception is thrown.
|
||||
@end deffn
|
||||
|
||||
@deffn {Scheme Procedure} register-parameter! parameter
|
||||
Add @var{parameter}, a @code{<gdb:parameter>} object, to @value{GDBN}'s
|
||||
list of parameters.
|
||||
It is an error to register a parameter more than once.
|
||||
The result is unspecified.
|
||||
@end deffn
|
||||
|
||||
@deffn {Scheme Procedure} parameter? object
|
||||
Return @code{#t} if @var{object} is a @code{<gdb:parameter>} object.
|
||||
Otherwise return @code{#f}.
|
||||
@end deffn
|
||||
|
||||
@deffn {Scheme Procedure} parameter-value parameter
|
||||
Return the value of @var{parameter} which may either be
|
||||
a @code{<gdb:parameter>} object or a string naming the parameter.
|
||||
@end deffn
|
||||
|
||||
@deffn {Scheme Procedure} set-parameter-value! parameter new-value
|
||||
Assign @var{parameter} the value of @var{new-value}.
|
||||
The argument @var{parameter} must be an object of type @code{<gdb:parameter>}.
|
||||
@value{GDBN} does validation when assignments are made.
|
||||
@end deffn
|
||||
|
||||
When a new parameter is defined, its type must be specified. The
|
||||
available types are represented by constants defined in the @code{gdb}
|
||||
module:
|
||||
|
||||
@vtable @code
|
||||
@item PARAM_BOOLEAN
|
||||
The value is a plain boolean. The Guile boolean values, @code{#t}
|
||||
and @code{#f} are the only valid values.
|
||||
|
||||
@item PARAM_AUTO_BOOLEAN
|
||||
The value has three possible states: true, false, and @samp{auto}. In
|
||||
Guile, true and false are represented using boolean constants, and
|
||||
@samp{auto} is represented using @code{#:auto}.
|
||||
|
||||
@item PARAM_UINTEGER
|
||||
The value is an unsigned integer. The value of 0 should be
|
||||
interpreted to mean ``unlimited''.
|
||||
|
||||
@item PARAM_ZINTEGER
|
||||
The value is an integer.
|
||||
|
||||
@item PARAM_ZUINTEGER
|
||||
The value is an unsigned integer.
|
||||
|
||||
@item PARAM_ZUINTEGER_UNLIMITED
|
||||
The value is an integer in the range @samp{[0, INT_MAX]}.
|
||||
A value of @samp{-1} means ``unlimited'', and other negative
|
||||
numbers are not allowed.
|
||||
|
||||
@item PARAM_STRING
|
||||
The value is a string. When the user modifies the string, any escape
|
||||
sequences, such as @samp{\t}, @samp{\f}, and octal escapes, are
|
||||
translated into corresponding characters and encoded into the current
|
||||
host charset.
|
||||
|
||||
@item PARAM_STRING_NOESCAPE
|
||||
The value is a string. When the user modifies the string, escapes are
|
||||
passed through untranslated.
|
||||
|
||||
@item PARAM_OPTIONAL_FILENAME
|
||||
The value is a either a filename (a string), or @code{#f}.
|
||||
|
||||
@item PARAM_FILENAME
|
||||
The value is a filename. This is just like
|
||||
@code{PARAM_STRING_NOESCAPE}, but uses file names for completion.
|
||||
|
||||
@item PARAM_ENUM
|
||||
The value is a string, which must be one of a collection of string
|
||||
constants provided when the parameter is created.
