Is it possible to combine the capabilities of a `FormatLogger` and of a `FileLogger` in `LoggingExtras.jl`?
Quite obviously, the first one helps formatting logging messages with the other sends them to appropriate files. Though I can’t figure how to use both capabilities at the same time.
Here is an example of a logger using the package documentation
```julia
function init_logger()
# fmt_logger = FormatLogger() do io,args
# println(io,args._module," | ","[",args.level,"] ",args.message)
# end
logger = TeeLogger(
global_logger(),
MinLevelLogger(FileLogger("info.log"), Logging.Info),
MinLevelLogger(FileLogger("warn.log"), Logging.Warn),
MinLevelLogger(FileLogger("error.log"), Logging.Error),
)
return logger
end
logger = init_logger()
with_logger(logger) do
@info "blablabla"
@warn "bliblibli"
@error "blobloblo"
end
```

All that `FileLogger` really does is to open the file and pass it to a `SimpleLogger`. So to use a “`FileLogger`” for `FormatLogger` you can just open the files yourself and pass the IO: `FormatLogger(fmt, open("info.log", "w"))`. Here is the full example:
```julia
function init_logger()
function fmt(io, args)
println(io, args._module, " | ", "[", args.level, "] ", args.message)
end
logger = TeeLogger(
global_logger(),
MinLevelLogger(FormatLogger(fmt, open("info.log", "w")), Logging.Info),
MinLevelLogger(FormatLogger(fmt, open("warn.log", "w")), Logging.Warn),
MinLevelLogger(FormatLogger(fmt, open("error.log", "w")), Logging.Error),
)
return logger
end
logger = init_logger()
with_logger(logger) do
@info "blablabla"
@warn "bliblibli"
@error "blobloblo"
end
```

Works like a charm, thanks !
