cilog 1.3.0

CiLog is a flexible integrated logging tool

CiLog

CiLog is a flexible integrated logging tool with color and custom bold font base on package logging.

Feature

• Colored console outputs
• Setting stack info output level
• Easier way to custom format for each level
• Substitute builtins.print: a new print grammar to use log!
• Command line script to substitute nohup cmd & with a "task completed reminder" feature.

Install

$ pip install cilog

New Features

1.2.0

• Add SUPPORT for excel table filling. Usage:

from cilog import fill_table


table_format = [['A', 'B', 'C', 'D', 'E', 'F', 'G'],
                ['da', 'db', 'dc', 'de'],
                ['sa', 'sb', 'sc', 'sd', 'sf']]

fill_table('./excel_test.xlsx', value='0.4013', x='C', y='db', z='sd', table_format=table_format)

1.1.5

• Add SUPPORT for error logging(such as raise ***), all the error message will go though the logger.error process. Note that you have to use set flag sub_print=True in create_logger() to use this function.
• Fix bug with package tqdm

1.1.4

• Tabular print SUPPORT: print(f'#T#!latex{table_list}') for latex format table string or print(f'#T#{table_list}') for markdown format table string.

1.1.3

• Bug fixed

1.1.2

• Automatically install dependencies when first running.

1.1.1

• bug fixed

1.1.0

• Add origin level. When we use sub_print=True, print(f'string') will act like normal builtin print function. Other levels like info, debug and mail, etc, should be specified by special notation like #IN#, #D# and #M#, etc.
• Support Table print in markdown format or latex format for data scientists.

1.0.2

• Bug fixed

1.0.1

• Bug fixed

1.0.0

• Develop print function substitute function. Now you can directly send parameter sub_print=True to create_logger for substituting print.
• A command line TOOL: cilog is available NOW! You don't have to use nohup cmd & any more! It will even send a EMAIL to you when your task completed! Please refer to the main document for how to use it.

0.3.0

• Substitute builtins.print using logger.substitute_print()
• A brand NEW way to use logger! You can just use print()!
• By using print, you need to know the easier logger grammar. Please refer to the main document.

0.2.1

• Bug fixed: Now the logger can automatically create the directory for log file.

0.2.0

• Eliminate ipt_info, instead you can use logger.important() to log important info.
• adding feature of sending email. By Default, after setting enable_mail and mail_setting, all message log by logger.mail() will be sent to the specific email address according to mail_setting.

0.1.1

• After log file's line_length is greater than 1e+4, it will automatically backup the log file with localtime then new a log file.

0.1.0

• new parameter ipt_info

Advance Usage

Substitute builtins.print

The only step you shoud do is:

from cilog import create_logger
create_logger(sub_print=True)

# Then: you can even execute the following scripts 
# in other files if only you have run these two lines
# in the same system process

# Let us just try!


print('i=1') # info: i=1
print('i', '=', '1') # info: i = 1
print('#D#Here!') # Debug: Here! [#d#, #DEbu#, #dEBug#, ... are all valid!]
print('#W#warning') # Warning ...
# Similarly, #e# #ER# ...: error, #I# #IM# ...: important,
# #C# #CRE# ...: critical, #M# #MA# #Mail# ...: mail.

Grammar: The way to use logger.info is just use print, and the way to use other level is to type the first several characters of the level name between simbol #.

You can use print everywhere which actually use the logger you created to output! Meanwhile, you can use any print features, like end=* or sep=* ... but do not use file=*, because the logger only monitor the standard output.

Elaborate Example:

from cilog import create_logger


def call_error():
    print('#E#Exception')

'''
mail_setting = {
            mailhost:   string or tuple - YourMailHost or (host, port),
            fromaddr:   string          - YourSenderAddress,
            toaddrs:    list(string)    - List of YourTargetAddresses,
            subject:    string          - Mail Subject,
            credentials:tuple           - (YourUsername, YourPassword),
            secure:     tuple           - () or (KeyfileName) or (KeyfileName, CertificatefileName)
                                            use the secure protocol (TLS),
            timeout:    float           - Default 1.0
        }
'''
mail_setting = {
    'mailhost': ('*****', int(**)),
    'fromaddr': '****@*****',
    'toaddrs': ['****@****', '***@***'],
    'subject': 'CiLog test',
    'credentials': ('***@**', '****')
}
create_logger(name='l1', file='./log.log', enable_mail=True,
                       mail_setting=mail_setting, sub_print=True)
# The simplest usage `create_logger(sub_print=True)`
print('origin')
table_list = [['Tox21', 'Clintox'], [1, 2], [3, 4]]
print(f'#t#{table_list}')   # print table in markdown format
# |   Tox21 |   Clintox |
# |--------:|----------:|
# |       1 |         2 |
# |       3 |         4 |

print(f'#t#!latex{table_list}') # latex format table
# \begin{tabular}{rr}
# \toprule
#  Tox21 &  Clintox \\
# \midrule
#      1 &        2 \\
#      3 &        4 \\
# \bottomrule
# \end{tabular}

print('#IN#start')
print('#D#here')
print('#W#warn')
call_error()
print('#C#Program exit.')
print('#IM#lal')
# print('#M#test')

Command line usage

First step

Run $ cilog [any cmd] to create default config file at $HOME$/.cilog/config.json then modify it with your custom setting.

Run a cmd

For example:

$ cilog python my_algorithm.py --lr 0.01 --epoch 100

it is equal to:

$ nohup python my_algorithm.py --lr 0.01 --epoch 100 > cilog.log 2>&1 &

-e usage:

$ cilog -e python my_algorithm.py --lr 0.01 --epoch 100

There is no different to the previous example but will send you A EMAIL when the task finished [Using your default setting]. It is especially useful when your program is time comsuming.

-c [config_file]: use your own config file instead of the default one.

-r [redirect_file]: redirect the output to a file instead of cilog.log.

Ps: Do not use the same cmdline parameters -c -e -r in your program, or it will cause an error.
