Logger.Formatter.compile
You're seeing just the function
compile
, go back to Logger.Formatter module for more information.
Specs
compile(binary() | nil) :: [pattern() | binary()]
compile(pattern) :: pattern when pattern: {module(), function :: atom()}
Compiles a format string into a data structure that format/5
can handle.
Check the module doc for documentation on the valid parameters that
will be interpolated in the pattern. If you pass nil
as the pattern,
the pattern defaults to:
"\n$time $metadata[$level] $levelpad$message\n"
If you want to customize formatting through a custom formatter, you can
pass a {module, function}
tuple as the pattern
.
iex> Logger.Formatter.compile("$time $metadata [$level] $message\n")
[:time, " ", :metadata, " [", :level, "] ", :message, "\n"]
iex> Logger.Formatter.compile({MyLoggerFormatter, :format})
{MyLoggerFormatter, :format}
