| 135 | "\nGeneral information about entering breakpoint commands \n\ |
| 136 | ------------------------------------------------------ \n\ |
| 137 | \n\ |
| 138 | This command will cause you to be prompted to enter the command or set \n\ |
| 139 | of commands you wish to be executed when the specified breakpoint is \n\ |
| 140 | hit. You will be told to enter your command(s), and will see a '> ' \n\ |
| 141 | prompt. Because you can enter one or many commands to be executed when \n\ |
| 142 | a breakpoint is hit, you will continue to be prompted after each \n\ |
| 143 | new-line that you enter, until you enter the word 'DONE', which will \n\ |
| 144 | cause the commands you have entered to be stored with the breakpoint \n\ |
| 145 | and executed when the breakpoint is hit. \n\ |
| 146 | \n\ |
| 147 | Syntax checking is not necessarily done when breakpoint commands are \n\ |
| 148 | entered. An improperly written breakpoint command will attempt to get \n\ |
| 149 | executed when the breakpoint gets hit, and usually silently fail. If \n\ |
| 150 | your breakpoint command does not appear to be getting executed, go \n\ |
| 151 | back and check your syntax. \n\ |
| 152 | \n\ |
| 153 | \n\ |
| 154 | Special information about PYTHON breakpoint commands \n\ |
| 155 | ---------------------------------------------------- \n\ |
| 156 | \n\ |
| 157 | You may enter either one line of Python or multiple lines of Python \n\ |
| 158 | (including defining whole functions, if desired). If you enter a \n\ |
| 159 | single line of Python, that will be passed to the Python interpreter \n\ |
| 160 | 'as is' when the breakpoint gets hit. If you enter function \n\ |
| 161 | definitions, they will be passed to the Python interpreter as soon as \n\ |
| 162 | you finish entering the breakpoint command, and they can be called \n\ |
| 163 | later (don't forget to add calls to them, if you want them called when \n\ |
| 164 | the breakpoint is hit). If you enter multiple lines of Python that \n\ |
| 165 | are not function definitions, they will be collected into a new, \n\ |
| 166 | automatically generated Python function, and a call to the newly \n\ |
| 167 | generated function will be attached to the breakpoint. Important \n\ |
| 168 | Note: Because loose Python code gets collected into functions, if you \n\ |
| 169 | want to access global variables in the 'loose' code, you need to \n\ |
| 170 | specify that they are global, using the 'global' keyword. Be sure to \n\ |
| 171 | use correct Python syntax, including indentation, when entering Python \n\ |
| 172 | breakpoint commands. \n\ |
| 173 | \n\ |
| 174 | Example Python one-line breakpoint command: \n\ |
| 175 | \n\ |
| 176 | (lldb) breakpoint command add -p 1 \n\ |
| 177 | Enter your Python command(s). Type 'DONE' to end. \n\ |
| 178 | > print \"Hit this breakpoint!\" \n\ |
| 179 | > DONE \n\ |
| 180 | \n\ |
Johnny Chen | 4c1b218 | 2010-09-10 19:34:12 +0000 | [diff] [blame] | 181 | As a convenience, this also works for a short Python one-liner: \n\ |
Johnny Chen | b81ed0d | 2010-09-11 00:18:09 +0000 | [diff] [blame] | 182 | (lldb) breakpoint command add -p 1 -o \"import time; print time.asctime()\" \n\ |

Chris Lattner | 24943d2 | 2010-06-08 16:52:24 +0000 | [diff] [blame] | 197 | Example multiple line Python breakpoint command, using function definition: \n\ |

| 203 | > print out_string \n\ |

| 209 | Example multiple line Python breakpoint command, using 'loose' Python: \n\ |
| 210 | \n\ |
| 211 | (lldb) breakpoint command add -p 1 \n\ |
| 212 | Enter your Python command(s). Type 'DONE' to end. \n\ |
| 213 | > global bp_count \n\ |

| 215 | > print \"Hit this breakpoint \" + repr(bp_count) + \" times!\" \n\ |
| 216 | > DONE \n\ |
| 217 | \n\ |
| 218 | In this case, since there is a reference to a global variable, \n\ |
| 219 | 'bp_count', you will also need to make sure 'bp_count' exists and is \n\ |
| 220 | initialized: \n\ |
| 221 | \n\ |
| 222 | (lldb) script \n\ |
| 223 | >>> bp_count = 0 \n\ |
| 224 | >>> quit() \n\ |

| 229 | Final Note: If you get a warning that no breakpoint command was generated, \n\ |
| 230 | but you did not get any syntax errors, you probably forgot to add a call \n\ |
| 231 | to your functions. \n\ |
