Cron

I have found a useful cron-like script for windows using python. Although it is relatively old (last update being in 2011) it still works really well.

I have applied some changes below to extend its functionality to allow you to put “dash” between numbers. e.g.

1-5
0-59

and so on, so that it is even more cron-like.

Changes are as follows:

def listing(expr):
    listing = [dash(x) for x in string.split(expr,',')]
    return [item for sublist in listing for item in sublist]

def dash(expr):
    value = [int(x) for x in string.split(expr,'-')]
    return range(min(value),max(value)+1)

def match(value, expr):

    if expr == '*':
        return 1
    values = listing(expr)

    #chapman edit to account for dashes
    for v in values:
        if v == value:
            #here for if there are no dashes
            return 1
    return 0
