| 48 | ------------------------------------------------------ \n\ |
| 49 | \n\ |
| 50 | This command will cause you to be prompted to enter the command or set \n\ |
| 51 | of commands you wish to be executed when the specified breakpoint is \n\ |
| 52 | hit. You will be told to enter your command(s), and will see a '> ' \n\ |
| 53 | prompt. Because you can enter one or many commands to be executed when \n\ |
| 54 | a breakpoint is hit, you will continue to be prompted after each \n\ |
| 55 | new-line that you enter, until you enter the word 'DONE', which will \n\ |
| 56 | cause the commands you have entered to be stored with the breakpoint \n\ |
| 57 | and executed when the breakpoint is hit. \n\ |
| 58 | \n\ |
| 59 | Syntax checking is not necessarily done when breakpoint commands are \n\ |
| 60 | entered. An improperly written breakpoint command will attempt to get \n\ |
| 61 | executed when the breakpoint gets hit, and usually silently fail. If \n\ |
| 62 | your breakpoint command does not appear to be getting executed, go \n\ |
| 63 | back and check your syntax. \n\ |
| 64 | \n\ |

Jim Ingham | 73260da | 2012-04-25 01:05:21 +0000 | [diff] [blame] | 66 | Special information about PYTHON breakpoint commands \n\ |
| 67 | ---------------------------------------------------- \n\ |
| 68 | \n\ |
| 69 | You may enter either one line of Python or multiple lines of Python \n\ |
| 70 | (including defining whole functions, if desired). If you enter a \n\ |
| 71 | single line of Python, that will be passed to the Python interpreter \n\ |
| 72 | 'as is' when the breakpoint gets hit. If you enter function \n\ |
| 73 | definitions, they will be passed to the Python interpreter as soon as \n\ |
| 74 | you finish entering the breakpoint command, and they can be called \n\ |
| 75 | later (don't forget to add calls to them, if you want them called when \n\ |
| 76 | the breakpoint is hit). If you enter multiple lines of Python that \n\ |
| 77 | are not function definitions, they will be collected into a new, \n\ |
| 78 | automatically generated Python function, and a call to the newly \n\ |
| 79 | generated function will be attached to the breakpoint. \n\ |
| 80 | \n\ |
| 81 | This auto-generated function is passed in two arguments: \n\ |
| 82 | \n\ |
| 83 | frame: an SBFrame object representing the frame which hit the breakpoint. \n\ |
| 84 | From the frame you can get back to the thread and process. \n\ |
| 85 | bp_loc: the number of the breakpoint location that was hit. \n\ |
| 86 | This is useful since one breakpoint can have many locations. \n\ |
| 87 | \n\ |
| 88 | Important Note: Because loose Python code gets collected into functions, \n\ |
| 89 | if you want to access global variables in the 'loose' code, you need to \n\ |
| 90 | specify that they are global, using the 'global' keyword. Be sure to \n\ |
| 91 | use correct Python syntax, including indentation, when entering Python \n\ |
| 92 | breakpoint commands. \n\ |
| 93 | \n\ |
| 94 | As a third option, you can pass the name of an already existing Python function \n\ |
| 95 | and that function will be attached to the breakpoint. It will get passed the \n\ |
| 96 | frame and bp_loc arguments mentioned above. \n\ |
| 97 | \n\ |

| 141 | \n\ |
| 142 | In this case, since there is a reference to a global variable, \n\ |
| 143 | 'bp_count', you will also need to make sure 'bp_count' exists and is \n\ |
