This module contains definitions for formatting log message to write it to output.

Log message format is defined by using text-format-heavy syntax. Variables available are:

• level - message severity level. Variable format can be specified in form of selector[~convert], where:

  • selector is name for level name, value for level integer value, syslog for name of syslog equivalent of the level.
  • convert is u for upper case, l for lower case, t for title case (all words capitalized).

  Default format corresponds to name. For example, use {level:~l} to output level name in lower case.

• source - message source (module name)
• location - location from where message was logged (in form of (line, column)).
• line - source file line number from where message was logged.
• file - source file name from where message was logged.
• package - name of the package from where message was logged.
• time - message time
• message - message string itself
• fullcontext - full set of current context variable values, in name=value; name=value; form.
• Also all variables from context are available.
