Sorry if this has been asked before.

Is it possible to do something like:
config :logger, :console, format: “[$date][$time][$node][$level][$file][$function][$line] $message\n”

where the logger automatically puts in the function, line and file name?

for example, in C/C++ you can use the macros __ FILE __ and __ LINE __.

I mostly want to be lazy and cut and paste my:

Logger.warn “no pattern matched”

with adding the specifics.

The file, function and line are included in in the metadata, not the format. These are the acceptable format options:

Formatting

The valid parameters you can use are:

$time - time the log message was sent
$date - date the log message was sent
$message - the log message
$level - the log level
$node - the node that prints the message
$metadata - user controlled data presented in “key=val key2=val2” format
$levelpad - sets to a single space if level is 4 characters long, otherwise set to the empty space. Used to align the message after level.

Metadata

In addition to the keys provided by the user via Logger.metadata/1, the following extra keys are available to the :metadata list:

:application - the current application
:module - the current module
:function - the current function
:file - the current file
:line - the current line
:pid - the current process ID

Try this:

config :logger, :console, format: "[$date][$time][$node][$level] $metadata$message\n"
  metadata: [:file, :function, :line]

Thanks wfgilman,

that worked great.

I just had a drop in a comma after the:
$metadata$message\n",
