| "\nGeneral information about entering breakpoint commands \n\ |
| ------------------------------------------------------ \n\ |
| \n\ |
| This command will cause you to be prompted to enter the command or set \n\ |
| of commands you wish to be executed when the specified breakpoint is \n\ |
| hit. You will be told to enter your command(s), and will see a '> ' \n\ |
| prompt. Because you can enter one or many commands to be executed when \n\ |
| a breakpoint is hit, you will continue to be prompted after each \n\ |
| new-line that you enter, until you enter the word 'DONE', which will \n\ |
| cause the commands you have entered to be stored with the breakpoint \n\ |
| and executed when the breakpoint is hit. \n\ |
| \n\ |
| Syntax checking is not necessarily done when breakpoint commands are \n\ |
| entered. An improperly written breakpoint command will attempt to get \n\ |
| executed when the breakpoint gets hit, and usually silently fail. If \n\ |
| your breakpoint command does not appear to be getting executed, go \n\ |
| back and check your syntax. \n\ |
| \n\ |
| \n\ |
| Special information about PYTHON breakpoint commands \n\ |
| ---------------------------------------------------- \n\ |
| \n\ |
| You may enter either one line of Python or multiple lines of Python \n\ |
| (including defining whole functions, if desired). If you enter a \n\ |
| single line of Python, that will be passed to the Python interpreter \n\ |
| 'as is' when the breakpoint gets hit. If you enter function \n\ |
| definitions, they will be passed to the Python interpreter as soon as \n\ |
| you finish entering the breakpoint command, and they can be called \n\ |
| later (don't forget to add calls to them, if you want them called when \n\ |
| the breakpoint is hit). If you enter multiple lines of Python that \n\ |
| are not function definitions, they will be collected into a new, \n\ |
| automatically generated Python function, and a call to the newly \n\ |
| generated function will be attached to the breakpoint. Important \n\ |
| Note: Because loose Python code gets collected into functions, if you \n\ |
| want to access global variables in the 'loose' code, you need to \n\ |
| specify that they are global, using the 'global' keyword. Be sure to \n\ |
| use correct Python syntax, including indentation, when entering Python \n\ |
| breakpoint commands. \n\ |
| \n\ |
| Example Python one-line breakpoint command: \n\ |
| \n\ |
| (lldb) breakpoint command add -s python 1 \n\ |
| Enter your Python command(s). Type 'DONE' to end. \n\ |
| > print \"Hit this breakpoint!\" \n\ |
| > DONE \n\ |
| \n\ |
| As a convenience, this also works for a short Python one-liner: \n\ |
| (lldb) breakpoint command add -s python 1 -o \"import time; print time.asctime()\" \n\ |
| (lldb) run \n\ |
| Launching '.../a.out' (x86_64) \n\ |
| (lldb) Fri Sep 10 12:17:45 2010 \n\ |
| Process 21778 Stopped \n\ |
| * thread #1: tid = 0x2e03, 0x0000000100000de8 a.out`c + 7 at main.c:39, stop reason = breakpoint 1.1, queue = com.apple.main-thread \n\ |
| 36 \n\ |
| 37 int c(int val)\n\ |
| 38 {\n\ |
| 39 -> return val + 3;\n\ |
| 40 }\n\ |
| 41 \n\ |
| 42 int main (int argc, char const *argv[])\n\ |
| (lldb) \n\ |
| \n\ |
| Example multiple line Python breakpoint command, using function definition: \n\ |
| \n\ |
| (lldb) breakpoint command add -s python 1 \n\ |
| Enter your Python command(s). Type 'DONE' to end. \n\ |
| > def breakpoint_output (bp_no): \n\ |
| > out_string = \"Hit breakpoint number \" + repr (bp_no) \n\ |
| > print out_string \n\ |
| > return True \n\ |
| > breakpoint_output (1) \n\ |
| > DONE \n\ |
| \n\ |
| \n\ |
| Example multiple line Python breakpoint command, using 'loose' Python: \n\ |
| \n\ |
| (lldb) breakpoint command add -s p 1 \n\ |
| Enter your Python command(s). Type 'DONE' to end. \n\ |
| > global bp_count \n\ |
| > bp_count = bp_count + 1 \n\ |
| > print \"Hit this breakpoint \" + repr(bp_count) + \" times!\" \n\ |
| > DONE \n\ |
| \n\ |
| In this case, since there is a reference to a global variable, \n\ |
| 'bp_count', you will also need to make sure 'bp_count' exists and is \n\ |
| initialized: \n\ |
| \n\ |
| (lldb) script \n\ |
| >>> bp_count = 0 \n\ |
| >>> quit() \n\ |
| \n\ |
| (lldb) \n\ |
| \n\ |
| \n\ |
| Final Note: If you get a warning that no breakpoint command was generated, \n\ |
| but you did not get any syntax errors, you probably forgot to add a call \n\ |
| to your functions. \n\ |
| \n\ |
| Special information about debugger command breakpoint commands \n\ |
| -------------------------------------------------------------- \n\ |
| \n\ |
| You may enter any debugger command, exactly as you would at the \n\ |
| debugger prompt. You may enter as many debugger commands as you like, \n\ |
| but do NOT enter more than one command per line. \n" ); |
