Set verbosity of debugging messages reported by editor. Only messages below or equal level specified in parameter will be shown, default is debugging level 1. Also, any of symbolic constants defined below (case insensitive), or starting part of them may be given instead of corresponding number.
Table 1.1. Explanation of debugging levels
0 | PANIC | Critical errors |
1 | CRITICAL | Critical errors, but at least the program can exit somewhat gracefully |
2 | ERROR | Usual errors |
3 | WARNING | Comments about some unusual behavior |
4 | INFO | Information about some internal behavior |
5 | DEBUG | Debugging messages |
Setting this to -1 mean no debug messages will be shown at all, not even the most critical ones. Debugging messages are sent to STDERR.
