Parameter.__init__(name, command_class, parameter_class [, enum_sequence]) the object initializer for parameter registers the new parameter with gdb This initializer is normally invoked from the subclass’ own __init__ method Name is the name of the new parameter If name consists of multiple words, then the initial words are looked for as. I'd like to pass some command line arguments to a python script run via gdb command, but importing the gdb module in python removes the argv attribute from sys. Otherwise, the parameter’s value is converted to a python value of the appropriate type, and returned
Gdb.history (number) return a value from gdb ’s value history (see value history) The number argument indicates which history element to return. There are many parameters that already exist and can be set in gdb Set follow fork and set charset Setting these parameters influences certain behavior in gdb Similarly, you can define parameters that can be used to influence behavior in custom python scripts and commands
A new parameter is implemented as an instance of the gdb.parameter class. Fortunately, gdb text user interface (tui) provides a way for developers to review their source code and debug simultaneously More excitingly, in gdb 7, python interpreter was built into gdb This feature offers more straightforward ways to customize gdb printers and commands through the python library. You can get quick online help for gdb ’s python api by issuing the command python help (gdb) Functions and methods which have two or more optional arguments allow them to be specified using keyword syntax
This allows passing some optional arguments while skipping others Gdb.some_function('foo', bar = 1, baz = 2). That way i can have the breakpoint determined in the first script (that launches gdb), either by command line argument or some other means, and use it in the sourced script So far i have tried setting gdb variables in the subprocess (via set), but when the sourced script is run those variables are not in scope.
