| 12 * WorkShop Debugging Tools. What are these tools and why are they important? | |
| 13 * There are two main tools here. The first tool is a tool for delaying or | |
| 14 * stopping gvim during startup. The second tool is a protocol log tool. | |
| 15 * | |
| 16 * The startup delay tool is called wsdebug_wait(). This is very important for | |
| 17 * debugging startup problems because gvim will be started automatically from | |
| 18 * workshop and cannot be run directly from a debugger. The only way to debug | |
| 19 * a gvim started by workshop is by attaching a debugger to it. Without this | |
| 20 * tool all starup code will have completed before you can get the pid and | |
| 21 * attach. | |
| 22 * | |
| 23 * The second tool is a protocol log tool. The workshop editor server and gvim | |
| 24 * pass information back and forth during a workshop session. Sometimes it is | |
| 25 * very important to peruse this conversation in order to understand what is | |
| 26 * happening. The wsdebug_log_init() call sets up this protocol log tool and | |
| 27 * wsdebug() and wstrace() calls output the information to the log. | |
| 28 * | |
| 29 * This code must have WSDEBUG defined for it to be compiled into vim/gvim. | |
