will log4rs support file size control and rolling file ?

Yep, appender configuration's pretty rudimentary right now, but log rotation is definitely something I want to add.

[Reposkeeper-zz]

I like this lib. But log rotation is a rigid requirement for me. Maybe I should not ask , but I really want to know is this requirement in schedule already?

It's part of some expansion I have been meaning to do. I'll hack on it over the weekend.

[Reposkeeper-zz]

That's great，I am looking forward to it

Now that log4rs 0.4 is released, I'm going to start tackling this. I think I'll probably work on it in a separate repo/crate initially until the API gets worked out, but then move it in since it's such a core concept.

While you're thinking about the API, it would be nice to support external rotation utilities like logrotate. I think that basically means exposing a method which causes appenders to reopen their log files.

[sfackler]

I was planning on having a similar setup to Logback, where there's a "triggering policy" that decides when the log should roll, and a "rotation policy" that decides what to do at that point. I think it should be possible to write a triggering policy that the logback postrotate command can poke, and a rotation policy that just closes and reopens the file.

That sounds great!

I'm working on this here: https://github.com/sfackler/log4rs-rolling-file

Not quite ready for a release yet, but the basics are there.

This is now on crates.io: https://crates.io/crates/log4rs-rolling-file

It's still missing some functionality like TimeBasedRollingPolicy which is a bit weird from an API perspective but probably the most common policy people actually use, so I'm going to keep it in a separate crate for now until that gets worked out.
