color_bucket_logger.term_mapper module

class color_bucket_logger.term_mapper.TermColorMapper(fmt=None, default_color_by_attr=None, color_groups=None, format_attrs=None, auto_color=False)

Bases: color_bucket_logger.mapper.BaseColorMapper

get_colors_for_record(record_context, format_attrs)

For a record_context dict, compute color for each field and return a color dict

get_level_color(levelname, levelno)

return color idx for logging levelname and levelno

get_name_color(name, perturb=None)

return color idx for ‘name’ string

get_process_colors(record_context)

Given process/thread info, return reasonable colors for them.

Roughly:

• attempts to get a unique color per ‘processName’

• attempts to get a unique color per ‘process’ (pid)

  • attempt to make those the same for “MainProcess”
  • for any other ‘processName’, the pname color and the pid color can be different

• if ‘threadName’ is “MainThread”, make tname_color and tid_color match “MainProcess” pname_color and pid_color
• other ‘threadName’ values get a new color and new tid_color

Notes

This doesn’t track any state so there is no ordering or prefence to the colors given out.

Parameters:record_context (dict) – The log record_context to calculate process colors for Returns:The color indexes for ‘processName’, ‘process’, ‘threadName’, and ‘thread’ Return type:int, int, int, int

get_thread_color(threadid)

Calculate the color index for a threadid (tid) number

Parameters:threadid (int) – The value of the LogRecord.threadid attribute (the tid) Returns:

• int
• The color index to use
