Classes

class Timestamp (silent='auto', level=None)

Create a controller for timed messages.

You can specify the degree of verbosity and also an indentation level. The verbosity affects the display of the info, warning, and error methods that are defined in this class, but can also affects messages emitted by other parts of the application, such as:

  • the display of the number of results in searches
  • the header that is displayed after the incantation of TF.

Parameters

silent : string, optional SILENT_D

The verbosity. Here are the values and their effects:

"verbose" or False: Show all info, warning, error messages. In incantation headers, show the full metadata of all features.

"auto": Like "verbose", but in incantation headers, show the feature descriptions only, not the full metadata.

"terse" or None: (default) Like "auto", but do not show log messages.

"deep" or True: Like "terse" but do not show log and warning messages. Do not show fetched datasets between the incantation and the header, and do not show the header either. Do not show the number of results after searches.
