12 * NetBeans 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 nbdebug_wait(). This is very important for
|
|
|
17 * debugging startup problems because gvim will be started automatically from
|
|
|
18 * netbeans and cannot be run directly from a debugger. The only way to debug
|
|
|
19 * a gvim started by netbeans 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 log tool.
|
|
|
24 *
|
|
|
25 * This code must have NBDEBUG defined for it to be compiled into vim/gvim.
