Todo

Modernize this, with type hint etc.

class LogFormatter(color, *args, **kwargs)

Bases: Formatter

Logging formatter supporting colorized output.

COLOR_CODES = {10: '\x1b[1;30m', 20: '\x1b[0;37m', 30: '\x1b[1;33m', 40: '\x1b[1;31m', 50: '\x1b[1;35m'}

RESET_CODE = '\x1b[0m'

__init__(color, *args, **kwargs)

Initialize the formatter with specified format strings.

Initialize the formatter either with the specified format string, or a default as described above. Allow for specialized date formatting with the optional datefmt argument. If datefmt is omitted, you get an ISO8601-like (or RFC 3339-like) format.

Use a style parameter of ‘%’, ‘{’ or ‘$’ to specify that you want to use one of %-formatting, str.format() ({}) formatting or string.Template formatting in your format string.

Changed in version 3.2: Added the style parameter.

format(record, *args, **kwargs)

Format the specified record as text.

The record’s attribute dictionary is used as the operand to a string formatting operation which yields the returned string. Before formatting the dictionary, a couple of preparatory steps are carried out. The message attribute of the record is computed using LogRecord.getMessage(). If the formatting string uses the time (as determined by a call to usesTime(), formatTime() is called to format the event time. If there is exception information, it is formatted using formatException() and appended to the message.

main(): Main function.
