This will stop in the first -function call in . - -Alternatively, if a statement terminated with an unhandled exception, -you can use pdb's post-mortem facility to inspect the contents of the -traceback: - - >>> - - >>> import pdb - >>> pdb.pm() - -The commands recognized by the debugger are listed in the next -section. Most can be abbreviated as indicated; e.g., h(elp) means -that 'help' can be typed as 'h' or 'help' (but not as 'he' or 'hel', -nor as 'H' or 'Help' or 'HELP'). Optional arguments are enclosed in -square brackets. - -A blank line repeats the previous command literally, except for -'list', where it lists the next 11 lines. - -Commands that the debugger doesn't recognize are assumed to be Python -statements and are executed in the context of the program being -debugged. Python statements can also be prefixed with an exclamation -point ('!'). This is a powerful way to inspect the program being -debugged; it is even possible to change variables. When an exception -occurs in such a statement, the exception name is printed but the -debugger's state is not changed. - -The debugger supports aliases, which can save typing. And aliases can -have parameters (see the alias help entry) which allows one a certain -level of adaptability to the context under examination. - -Multiple commands may be entered on a single line, separated by the -pair ';;'. No intelligence is applied to separating the commands; the -input is split at the first ';;', even if it is in the middle of a -quoted string. - -If a file ".pdbrc" exists in your home directory or in the current -directory, it is read in and executed as if it had been typed at the -debugger prompt. This is particularly useful for aliases. If both -files exist, the one in the home directory is read first and aliases -defined there can be overriden by the local file. - -Aside from aliases, the debugger is not directly programmable; but it -is implemented as a class from which you can derive your own debugger -class, which you can make as fancy as you like. - - -Debugger commands -================= - -h(elp) - Without argument, print the list of available commands. With - a command name as argument, print help about that command - (this is currently not implemented). - -w(here) - Print a stack trace, with the most recent frame at the bottom. - An arrow indicates the "current frame", which determines the - context of most commands. - -d(own) - Move the current frame one level down in the stack trace - (to a newer frame). - -u(p) - Move the current frame one level up in the stack trace - (to an older frame). - -b(reak) [ ([filename:]lineno | function) [, condition] ] - With a filename:line number argument, set a break there. If - filename is omitted, use the current file. With a function - name, set a break at the first executable line of that - function. Without argument, list all breaks. Each breakpoint - is assigned a number to which all the other breakpoint - commands refer. - - The condition argument, if present, is a string which must - evaluate to true in order for the breakpoint to be honored. - -tbreak [ ([filename:]lineno | function) [, condition] ] - Temporary breakpoint, which is removed automatically when it - is first hit. The arguments are the same as break. - -cl(ear) [bpnumber [bpnumber ...] ] - With a space separated list of breakpoint numbers, clear those - breakpoints. Without argument, clear all breaks (but first - ask confirmation). - -disable bpnumber [bpnumber ...] - Disables the breakpoints given as a space separated list of - breakpoint numbers. Disabling a breakpoint means it cannot - cause the program to stop execution, but unlike clearing a - breakpoint, it remains in the list of breakpoints and can be - (re-)enabled. - -enable bpnumber [bpnumber ...] - Enables the breakpoints specified. - -ignore bpnumber count - Sets the ignore count for the given breakpoint number. If - count is omitted, the ignore count is set to 0. A breakpoint - becomes active when the ignore count is zero. When non-zero, - the count is decremented each time the breakpoint is reached - and the breakpoint is not disabled and any associated - condition evaluates to true. - -condition bpnumber condition - condition is an expression which must evaluate to true before - the breakpoint is honored. If condition is absent, any - existing condition is removed; i.e., the breakpoint is made - unconditional. - -s(tep) - Execute the current line, stop at the first possible occasion - (either in a function that is called or in the current function). - -n(ext) - Continue execution until the next line in the current function - is reached or it returns. - -unt(il) - Continue execution until the line with a number greater than the - current one is reached or until the current frame returns. - -r(eturn) - Continue execution until the current function returns. - -run [args...] - Restart the debugged python program. If a string is supplied it is - splitted with "shlex", and the result is used as the new sys.argv. - History, breakpoints, actions and debugger options are preserved. - "restart" is an alias for "run". - -c(ont(inue)) - Continue execution, only stop when a breakpoint is encountered. - -l(ist) [first [,last]] - List source code for the current file. - Without arguments, list 11 lines around the current line - or continue the previous listing. - With one argument, list 11 lines starting at that line. - With two arguments, list the given range; - if the second argument is less than the first, it is a count. - -a(rgs) - Print the argument list of the current function. - -p expression - Print the value of the expression. - -(!) statement - Execute the (one-line) statement in the context of the current - stack frame. The exclamation point can be omitted unless the - first word of the statement resembles a debugger command. To - assign to a global variable you must always prefix the command - with a 'global' command, e.g.: - (Pdb) global list_options; list_options = ['-l'] - (Pdb) - - -whatis arg - Prints the type of the argument. - -alias [name [command]] - Creates an alias called 'name' that executes 'command'. The - command must *not* be enclosed in quotes. Replaceable - parameters can be indicated by %1, %2, and so on, while %* is - replaced by all the parameters. If no command is given, the - current alias for name is shown. If no name is given, all - aliases are listed. - - Aliases may be nested and can contain anything that can be - legally typed at the pdb prompt. Note! You *can* override - internal pdb commands with aliases! Those internal commands - are then hidden until the alias is removed. Aliasing is - recursively applied to the first word of the command line; all - other words in the line are left alone. - - As an example, here are two useful aliases (especially when - placed in the .pdbrc file): - - #Print instance variables (usage "pi classInst") - alias pi for k in %1.__dict__.keys(): print "%1.",k,"=",%1.__dict__[k] - #Print instance variables in self - alias ps pi self - -unalias name - Deletes the specified alias. - -q(uit) - Quit from the debugger. - The program being executed is aborted.
