| 119 | "\nGeneral information about entering breakpoint commands \n\ |
| 120 | ------------------------------------------------------ \n\ |
| 121 | \n\ |
| 122 | This command will cause you to be prompted to enter the command or set \n\ |
| 123 | of commands you wish to be executed when the specified breakpoint is \n\ |
| 124 | hit. You will be told to enter your command(s), and will see a '> ' \n\ |
| 125 | prompt. Because you can enter one or many commands to be executed when \n\ |
| 126 | a breakpoint is hit, you will continue to be prompted after each \n\ |
| 127 | new-line that you enter, until you enter the word 'DONE', which will \n\ |
| 128 | cause the commands you have entered to be stored with the breakpoint \n\ |
| 129 | and executed when the breakpoint is hit. \n\ |
| 130 | \n\ |
| 131 | Syntax checking is not necessarily done when breakpoint commands are \n\ |
| 132 | entered. An improperly written breakpoint command will attempt to get \n\ |
| 133 | executed when the breakpoint gets hit, and usually silently fail. If \n\ |
| 134 | your breakpoint command does not appear to be getting executed, go \n\ |
| 135 | back and check your syntax. \n\ |
| 136 | \n\ |
| 137 | \n\ |
| 138 | Special information about PYTHON breakpoint commands \n\ |
| 139 | ---------------------------------------------------- \n\ |
| 140 | \n\ |
| 141 | You may enter either one line of Python or multiple lines of Python \n\ |
| 142 | (including defining whole functions, if desired). If you enter a \n\ |
| 143 | single line of Python, that will be passed to the Python interpreter \n\ |
| 144 | 'as is' when the breakpoint gets hit. If you enter function \n\ |
| 145 | definitions, they will be passed to the Python interpreter as soon as \n\ |
| 146 | you finish entering the breakpoint command, and they can be called \n\ |
| 147 | later (don't forget to add calls to them, if you want them called when \n\ |
| 148 | the breakpoint is hit). If you enter multiple lines of Python that \n\ |
| 149 | are not function definitions, they will be collected into a new, \n\ |
| 150 | automatically generated Python function, and a call to the newly \n\ |
| 151 | generated function will be attached to the breakpoint. Important \n\ |
| 152 | Note: Because loose Python code gets collected into functions, if you \n\ |
| 153 | want to access global variables in the 'loose' code, you need to \n\ |
| 154 | specify that they are global, using the 'global' keyword. Be sure to \n\ |
| 155 | use correct Python syntax, including indentation, when entering Python \n\ |
| 156 | breakpoint commands. \n\ |
| 157 | \n\ |
| 158 | Example Python one-line breakpoint command: \n\ |
| 159 | \n\ |
| 160 | (lldb) breakpoint command add -p 1 \n\ |
| 161 | Enter your Python command(s). Type 'DONE' to end. \n\ |
| 162 | > print \"Hit this breakpoint!\" \n\ |
| 163 | > DONE \n\ |
| 164 | \n\ |
| 165 | Example multiple line Python breakpoint command, using function definition: \n\ |
| 166 | \n\ |
| 167 | (lldb) breakpoint command add -p 1 \n\ |
| 168 | Enter your Python command(s). Type 'DONE' to end. \n\ |
| 169 | > def breakpoint_output (bp_no): \n\ |
| 170 | > out_string = \"Hit breakpoint number \" + repr (bp_no) \n\ |
| 171 | > print out_string \n\ |
| 172 | > return True \n\ |
| 173 | > breakpoint_output (1) \n\ |
| 174 | > DONE \n\ |
| 175 | \n\ |
| 176 | \n\ |
| 177 | Example multiple line Python breakpoint command, using 'loose' Python: \n\ |
| 178 | \n\ |
| 179 | (lldb) breakpoint command add -p 1 \n\ |
| 180 | Enter your Python command(s). Type 'DONE' to end. \n\ |
| 181 | > global bp_count \n\ |
| 182 | > bp_count = bp_count + 1 \n\ |
| 183 | > print \"Hit this breakpoint \" + repr(bp_count) + \" times!\" \n\ |
| 184 | > DONE \n\ |
| 185 | \n\ |
| 186 | In this case, since there is a reference to a global variable, \n\ |
| 187 | 'bp_count', you will also need to make sure 'bp_count' exists and is \n\ |
| 188 | initialized: \n\ |
| 189 | \n\ |
| 190 | (lldb) script \n\ |
| 191 | >>> bp_count = 0 \n\ |
| 192 | >>> quit() \n\ |
| 193 | \n\ |
| 194 | (lldb) \n\ |
| 195 | \n\ |
| 196 | Special information debugger command breakpoint commands \n\ |
| 197 | --------------------------------------------------------- \n\ |
| 198 | \n\ |
| 199 | You may enter any debugger command, exactly as you would at the \n\ |
| 200 | debugger prompt. You may enter as many debugger commands as you like, \n\ |
| 201 | but do NOT enter more than one command per line. \n" ); |
