schrodinger.application.matsci.textlogger.timeit_logger_debug(func)¶: Log enter and leave time of a function in a class that may or may not contain self.logger attribute. If it doesn’t, logging will be done to the stdout.

schrodinger.application.matsci.textlogger.log_initial_data(logger, namespace, msgwidth=None, namespace_header='Command line options:', job_header='Job information')¶

Log information about the currently running job, if running under job control, and all information in the namespace object.

Parameters

namespace (object) – The object whose properties should be logged. In typical use, this is an argparse.Namespace object. All the values in the __dict__ of this object will be logged. Note that __dict__ does not contain the double-underscore class methods.
logger (logging.Logger) – The logger to log with
msgwidth (int) – The width of the log messages. Taken from the logger if not supplied
namespace_header (str or None) – If not None, this line will be printed above the logged namespace properties
job_header (str or None) – If not None, this line will be printed above the logged job properties

schrodinger.application.matsci.textlogger.log_namespace(namespace, logger, msgwidth=None, header='Command line options:')¶

Log the value of all properties on a object, such as logging all the parameters of an argparse.Namespace object.

Parameters

namespace (object) – The object whose properties should be logged. In typical use, this is an argparse.Namespace object. All the values in the __dict__ of this object will be logged. Note that __dict__ does not contain the double-underscore class methods.
logger (logging.Logger) – The logger to log with
msgwidth (int) – The width of the log messages. Taken from the logger if not supplied
header (str or None) – If not None, this line will be printed above the logged properties

schrodinger.application.matsci.textlogger.log_jobinfo(logger, msgwidth=None, header='Job information')¶

Log the information about the current running job if there is one.

Parameters

logger (logging.Logger) – The logger to log with
msgwidth (int) – The width of the log messages. Taken from the logger if not supplied
header (str or None) – If not None, this line will be printed above the logged properties

schrodinger.application.matsci.textlogger.run_jobs_with_update_logging(jobq, logfn, fraction=0.1, interval=3500, add_subjob_files=True)¶

Run all the current jobs in the JobDJ and logs progress information at semi-regular intervals so the user can track status

Parameters

jobq (schrodinger.job.queue.JobDJ) – The queue to run
logfn (callable) – A function that takes a string and a boolean timestamp argument and logs the string
fraction (float) – A value between 0 and 1. When this fraction of the total jobs has completed since the last log update, a new update will be triggered.
interval (int) – A new update will be triggered when this number of seconds have passed since the last log update
add_subjob_files (bool) – Add subjob files to the backend when a subjob completes (if a backend exists)

Note

fraction and interval are not obeyed strictly as updates can only be triggered when a job completes

schrodinger.application.matsci.textlogger.create_logger(logfilename=None, extension='-driver.log', related_filename=None, verbose=False, width=80, set_as_global=False)¶

Create a logger that can be used for logging information to a file

If running under job control, the log file this logger writes to will be added to the backend as a Log File.

Parameters

logfilename (str) – The name of the log file the logger should write to. If not supplied, the name will be based off the Job name if running under job control or based off of the basename of a related_file if not. As a last resort, the logfile name will use ‘logfile’ as the base name.
extension (str) – The extension to add to the file name if logfilename is not supplied.
related_filanem – The basename of this filename will be used as the base of the log file name IF logfilename is not supplied directly and we are not running under job control.
verbose (bool, or None) – Whether to enable verbose logging. If None, the verbosity is automatically setup according to debugging mode.
width (int) – Text width of the file
set_as_global (bool) – Whether to store the logger object as a module variable to be used when textlogger log functions are called from anywhere in the code.

Return type

(logging.Logger, str)

Returns

The logger and the name of the file it logs to.

schrodinger.application.matsci.textlogger.driver_logging(related_name=None, options=None, log_time=True, set_as_global=False)¶

Setup logging for the driver and log initial data and finish and run times

Parameters

related_name (str) – If not running under job control, the basename of this name will be used for the log file.
options (Namespace) – The options to log
log_time (bool) – Whether finish time and duration should be logged
set_as_global (bool) – Whether to store the logger object as a module variable to be used when textlogger log functions are called from anywhere in the code.

schrodinger.application.matsci.textlogger.get_global_logger()¶

Return the global logger object

Return type: logging.Logger
Returns: The global logger object

schrodinger.application.matsci.textlogger.pretty_time_delta(seconds)¶

Turn seconds into 1d 2h 3m 4s format

Parameters: seconds (float) – The number of seconds to convert
Return str: The time as string

schrodinger.application.matsci.textlogger.get_param_string(identifier, value, msgwidth)¶

Return a formatted line with identifier on the left and value right-justified. A line of ‘…’ will consume the intervening space.

Parameters

identifier (str) – description of the value
value (any) – the value of the descriptor
msgwidth (int) – the length of the msg

Return type

str

Returns

msg, formatted msg

class schrodinger.application.matsci.textlogger.GetLogger(logfilename, verbose, msgwidth)¶

Bases: object

Set up a textwrapped log file.

__init__(logfilename, verbose, msgwidth)¶

Create a GetLogger instance and process it.

Parameters

logfilename (str) – name of the log file
verbose (boolean) – enable verbose logging
msgwidth (int) – message width

class MyFormatter(msgwidth)¶

Bases: logging.Formatter

Extend logging.Formatter to customize the formats of different log levels and to textwrap the messages.

FORMATS = {10: '%(message)s', 20: '%(message)s', 'DEFAULT': '%(levelname)s (from function %(funcName)s):\n\n%(message)s\n'}¶

__init__(msgwidth)¶

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)¶

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.

setItUp()¶: Set up the logger.

schrodinger.application.matsci.textlogger.decode_base64_cmd(value)¶

Extract a BASE64 encoded command line from the full command line in value and return it as plain text string

Parameters: value (str) – A full job control command line containing a -cmd BASE64 etc. encoded command line string
Return type: str, str
Returns: The second value is the raw decoded BASE64 value and the first value is the raw value modified to be similar to what a user would type to on the command line (double quotes, redirects, parens, “python” removed, $SCHRODINGER/run added)

schrodinger.application.matsci.textlogger.close_logger_file_handlers(logger)¶

Close all logging.FileHandler’s for the given logger.

Parameters: logger (logging.Logger) – the logger object

schrodinger.application.matsci.textlogger.create_debug_logger(name, formatter=None, add_to_backend=None, stream=True)¶

Create a logger for module level debug usage.

Parameters

name (str) – the logger name
formatter ('logging.Formatter') – the logging format
add_to_backend (bool or None) – if True and logfile is created, add it to the backend. If None, add the file to backend in debug environment.
stream (bool) – if True and the newly created logfile is added to the backend, stream the file to the submission host

Returns

The logger created for this function

Return type

logging.Logger
