RotatingFileWriter

RotatingFileWriter is a simple write dispatcher. It opens file on the basis of strftime pattern and current time and automatically reopens it when pattern starts to interpolate into new name.

Example

Basic usage:

{:ok, writer} = RotatingFileWriter.start_link({"log/%F-%H.log", "Europe/Moscow"})

RotatingFileWriter.write(writer, "some log record")
# ...
RotatingFileWriter.write(writer, "some log record")

RotatingFileWriter.stop(writer)

Advanced usage:

{:ok, writer} = RotatingFileWriter.start_link(
  fn(time) ->
     Timex.format!(time, "log/{ISOweek-day}.log")
  end, # Custom file name generating function
  mode: [:write, :append, :sync], # Custom file open mode
  gen_server_opts: [name: RotatingLog], # GenServer options
  check_interval: 10000 # Custom interval of checking file name change, ms
)

RotatingFileWriter.write(writer, "some log record")

current_file_name = RotatingFileWriter.file_name(writer)

RotatingFileWriter.reopen(writer)

RotatingFileWriter.stop(writer)
