naivetools

Simple, straightforward Python tools for configuring, logging and other common tasks

NaiveLog

NaiveLog allows you to instantly get a logger that logs to stdout or stderr and can be reconfigured on the fly

Start your module with

from naivetools import naiveLog

log = naiveLog.naiveLog()
#or
log = naiveLog.naiveLog(name='myLog', level='DEBUG', target='stderr')

and you can log immediately with the usual python logging commands

log.debug(...)
log.info(...)
log.warning(...)
log.error(...)
log.critical(...)

try:
  ...
except:
  log.exception(...)

The output will look like 2014-01-12 11:36:47,642 ERROR [ 10669 test. : 6] Something is wrong

With date, time, log level, PID, module and function, line and message

NaiveConf

NaiveConf initializes a configuration object from Python files or strings and allows accessing parameters as attributes.

WARNING !!!Use this only if you control all the configuration files, since arbitraty code could be executed!!!

For example, you can define configuration file as simple Python code:

import datetime

def f(var):
    return str(var)

x = datetime.datetime(2013,1,1).date()
y = f(x)

L = [1,2,3, {'a': None}]

and then initialize and access a configuration object as

from naivetools import naiveConf
conf = naiveConf.NaiveConf('/path/to/conf.py')

print conf.x
conf.e = 100

assert conf['x'] == conf.x

for key, value in conf.items():
    print key, value

conf.required('x')
conf.required('L', 'Parameter L must be defined')

conf.default('Z', 5)
#If Z is not defined yet as a parameter, set it to 5
assert conf.Z == 5

conf.defaultNones(['e', 'f'])
#define e and f ans set them to None

conf.requiredAny(['f', 'g'], 'Either f or g or both must be defined')
#At least parameter must be defined

dConf = conf.getConf()
#Get a (shallow) copy of conf

dDict = conf.getConfDict()
#Get a dictionary of conf parameters

#Other ways to initialize
aConf = naiveConf.NaiveConf()
bConf = naiveConf.NaiveConf({'x': 5, 'f': None, 'li': [1,2,3]})
assert bConf.f is None

sConf = naiveConf.NaiveConf("a=5; b='g'")
assert sConf.b == 'g'

cConf = naiveConf.NaiveConf(bConf)
bConf.li[2] = 9
assert cConf.li == [1,2,9]
