2022-07-23logging: add logger system with levelsRobin Jarry
The built-in logging system is rather basic. Implement a multi-level logger to ease interpreting the logs. Configure the loggers with prefixes and microsecond precision for timestamps. Also, prefix the messages with the source file name and line number. Because of this, enabling the logs has a performance cost. They will only be enabled when redirecting aerc stdout to a file. Here is an example output: DEBUG 2022/07/20 12:52:34.536190 worker.go:45: PostAction *types.FetchDirectoryContents DEBUG 2022/07/20 12:52:34.536329 worker.go:92: ProcessAction *types.FetchDirectoryContents(2417) DEBUG 2022/07/20 12:52:34.536407 idler.go:159: idler (0xc00017c000) [idle:false,wait:false] =>(idle) [debounce] INFO 2022/07/20 12:52:34.536432 threadbuilder.go:59: 130 threads created in 220.796µs DEBUG 2022/07/20 12:52:34.536449 worker.go:75: ProcessMessage *types.DirectoryInfo(2416) DEBUG 2022/07/20 12:52:34.536453 idler.go:159: idler (0xc00017c000) [idle:false,wait:false] <=(idle) DEBUG 2022/07/20 12:52:34.536459 worker.go:45: PostAction *types.FetchDirectoryContents INFO 2022/07/20 12:52:34.536470 open.go:30: Fetching UID list INFO 2022/07/20 12:52:34.536689 threadbuilder.go:59: 130 threads created in 201.635µs Signed-off-by: Robin Jarry <robin@jarry.cc> Acked-by: Moritz Poldrack <moritz@poldrack.dev>
