Problem: The code style has to be checked manually.
Solution: Add basic code style checks in a test. Fix or avoid uncovered
problems.

|
|
* NetBeans Debugging Tools. What are these tools and why are they important?
|
|
* There are two main tools here. The first tool is a tool for delaying or
|
|
* stopping gvim during startup. The second tool is a protocol log tool.
|
|
*
|
|
* The startup delay tool is called nbdebug_wait(). This is very important for
|
|
* debugging startup problems because gvim will be started automatically from
|
|
* netbeans and cannot be run directly from a debugger. The only way to debug
|
|
* a gvim started by netbeans is by attaching a debugger to it. Without this
|
|
* tool all startup code will have completed before you can get the pid and
|
|
* attach.
|
|
*
|
|
* The second tool is a log tool.
|
|
*
|
|
* This code must have NBDEBUG defined for it to be compiled into vim/gvim.
