glog: how to add wrapper to log sinks ? Maybe move glog/internal/logsync out of internal ?

[Jan]

hi,

I want to add a prefix to the glog lines based on certain conditions of my program.

Browsing the glog code I found an example that seems exactly for that in package `glog/internal/logsync`:

https://github.com/golang/glog/blob/master/internal/logsink/logsink.go#L369 

 But unfortunately it is marked as `internal`, so not accessible. Any chances it could be made public ?

Or any suggestions on how to easily achieve the same result ?

Thanks!

Jan

ps.: I looked at other logging libraries, but I do require (use often) fine-grained level control of logging per file, like glog, and the libraries I checked (zap, logrus, zerolog, apex) don't seem to offer that.

A bit more of search and I found klog, which conveniently already provides SetLogFilter, which resolves the issue.

cheers

ps.: s/logsync/logsink -- sorry.
