gdb provides two commands for accessing the Python interpreter, and one related setting:
python-interactivecommand can be used to start an interactive Python prompt. To return to gdb, type the
EOFcharacter (e.g., Ctrl-D on an empty prompt).
Alternatively, a single-line Python command can be given as an argument and evaluated. If the command is an expression, the result will be printed; otherwise, nothing will be printed. For example:
(gdb) python-interactive 2 + 3 5
pythoncommand can be used to evaluate Python code.
If given an argument, the
python command will evaluate the
argument as a Python command. For example:
(gdb) python print 23 23
If you do not provide an argument to
python, it will act as a
multi-line command, like
define. In this case, the Python
script is made up of subsequent command lines, given after the
python command. This command list is terminated using a line
end. For example:
(gdb) python Type python script End with a line saying just "end". >print 23 >end 23
set python print-stack
set python print-stack: if
full, then full Python stack printing is enabled; if
none, then Python stack and message printing is disabled; if
message, the default, only the message component of the error is printed.
It is also possible to execute a Python script from the gdb interpreter:
script-extensionsetting. See Extending GDB.
python execfile ("script-name")
execfilePython built-in function, and thus is always available.
