Question about class ProgressBar(object):

[Kiny Wan]

Dear all, I find that the variable 'self.stelap' in progress_bar.py means the elapsed simulation times, however,  'self.stelap = self.stcurr - self.strtrt' is confused. Is ''self.strtrt' should be replaced with 'self.ststrt'?

 class ProgressBar(object):

def __init__(self, start, curr, end, dps=2):

        self.ststrt = start
        self.strtrt = curr
        self.stend = end
        self.dps = dps
        self._wstart = time.time()
        self._last_wallt = 0.0
        self._ncol = shutil.get_terminal_size()[0] or 80
        self._nbarcol = self._ncol - 24 - 2*len('{:.{}f}'.format(end, dps))
        self.advance_to(curr)
    def advance_to(self, t):
        self.stcurr = min(t, self.stend)
        self.stelap = self.stcurr - self.strtrt

No, the code is correct as-is.  This is needed to handle the case where one is restarting a simulation.  Here, the elapsed progress is the difference between where we currently are (self.stcurr) and where we are restarting from (st.rtrt).  This enables the progress bar to differentiate between progress which was made before the current restart action and that which has been made since we restarted; the former is signified by a + whilst the latter is signified by a =.
