msglist (list) –

A list containing the pypeit parameter strings. The last element of the list must be the argument and the variable. For example, to print:

[sensfunc]
    [[UVIS]]
        polycorrect = False

you should set msglist = ['sensfunc', 'UVIS', 'polycorrect = False'].

pypeitpar_text(msglist)

Prepare a text string with the pypeit par formatting.

Parameters:

msglist (list) –

A list containing the pypeit parameter strings. The last element of the list must be the argument and the variable. For example, to print:

[sensfunc]
    [[UVIS]]
        polycorrect = False

you should set msglist = ['sensfunc', 'UVIS', 'polycorrect = False'].

Returns:

parstring – The parameter string

Return type:

reset(log=None, verbosity=None, colors=True, log_to_stderr=None)

Needed so that there can be a default object for all modules, but also a dynamically defined log file.

reset_log_file(log)

set_logfile_and_verbosity(scriptname, verbosity)

Set the logfile name and verbosity level for a script run.

PypeIt scripts (with the exception of run_pypeit) default to verbosity level = 1. For certain scripts, having a more verbose output (with an accompanying log file) would be helpful for debugging purposes. This function provides the ability to set the msgs verbosity and create a log file for those certain scripts.

Log filenames have the form scriptname_YYYYMMDD_HHMM.log to differentiate between different runs of the script. Timestamp is UT.

Parameters:

• scriptname (str, optional) – The name of the calling script for use in the logfile

• verbosity (int, optional) – The requested verbosity, passed in from the argument parser. Verbosity level between 0 [none] and 2 [all]

test(msg)

Print a test message

warn(msg)

Print a warning message

work(msg)

Print a work in progress message
