The most useful class of the fundamentals package is The tools object, when added to the __main__ function of your cl-utils module, will do a lot of heavy lifting to set you up with some useful project tools. These include a logger, a default settings file and abilities to setup database connections and ssh tunnels.

For example, I can have a module living at the root of my python package with the following content:

# encoding: utf-8
*CL utils for myProject*

    myProjectCommand [-s <pathToSettingsFile>]

    -h, --help            show this help message
    -s, --settings        the settings file
################# GLOBAL IMPORTS ####################
import sys
import os
os.environ['TERM'] = 'vt100'
import glob
from docopt import docopt
from fundamentals import tools, times

def main(arguments=None):
    *The main function used when ```` is run as a single script from the cl, or when installed as a cl command*
    su = tools(
    arguments, settings, log, dbConn = su.setup()

    for arg, val in arguments.iteritems():
        if arg[0] == "-":
            varname = arg.replace("-", "") + "Flag"
            varname = arg.replace("<", "").replace(">", "")
        if isinstance(val, str) or isinstance(val, unicode):
            exec(varname + " = '%s'" % (val,))
            exec(varname + " = %s" % (val,))
        if arg == "--dbConn":
            dbConn = val
        log.debug('%s = %s' % (varname, val,))

    startTime = times.get_now_sql_datetime()
        '--- STARTING TO RUN THE AT %s' %


    if "dbConn" in locals() and dbConn:
    endTime = times.get_now_sql_datetime()
    runningTime = times.calculate_time_difference(startTime, endTime)'-- FINISHED ATTEMPT TO RUN THE AT %s (RUNTIME: %s) --' %
             (endTime, runningTime, ))


if __name__ == '__main__':

And within I will include:

    'console_scripts': ['myProjectCommand=myProject.cl_utils:main'],

And finally I also have a default-settings.yaml file at the root of my python package with the content:

version: 1
database settings:
    db: dryx_unit_testing
    host: localhost
    user: unittesting
    password: utpass
    sshPort: False
    loginPath: unittesting

# SSH TUNNEL - if a tunnel is required to connect to the database(s) then add setup here
# Note only one tunnel is setup - may need to change this to 2 tunnels in the future if
# code, static catalogue database and transient database are all on seperate machines.
ssh tunnel:
    use tunnel: True   # True | False
    remote user: username
    remote ip:
    remote datbase host: mydatabaseName
    port: 9002

logging settings:
            format: '* %(asctime)s - %(name)s - %(levelname)s (%(pathname)s > %(funcName)s > %(lineno)d) - %(message)s  '
            datefmt: '%Y/%m/%d %H:%M:%S'
            format: '* %(asctime)s - %(levelname)s: %(pathname)s:%(funcName)s:%(lineno)d > %(message)s'
            datefmt: '%H:%M:%S'
            format: '<div id="row" class="%(levelname)s"><span class="date">%(asctime)s</span>   <span class="label">file:</span><span class="filename">%(filename)s</span>   <span class="label">method:</span><span class="funcName">%(funcName)s</span>   <span class="label">line#:</span><span class="lineno">%(lineno)d</span> <span class="pathname">%(pathname)s</span>  <div class="right"><span class="message">%(message)s</span><span class="levelname">%(levelname)s</span></div></div>'
            datefmt: '%Y-%m-%d <span class= "time">%H:%M <span class= "seconds">%Ss</span></span>'
            class: logging.StreamHandler
            level: DEBUG
            formatter: console_style
            stream: ext://sys.stdout
            class: logging.handlers.GroupWriteRotatingFileHandler
            level: WARNING
            formatter: file_style
            filename: /Users/Dave/.config/myProject/myProject.log
            mode: w+
            maxBytes: 102400
            backupCount: 1
        level: WARNING
        handlers: [file,console]

Once the package is installed, from the terminal I can now run:


The first time this command is run (no arguments), a dedicated project directory is setup at ~/.config/myProject/. The default-settings.yaml file is copied to ~/.config/myProject/myProject.yaml and a log file created at ~/.config/myProject/myProject.log. Subsequent running of this command will read the settings from ~/.config/myProject/myProject.yaml, so any changes made to this file will be seen by the command. It’s also possible to pass in alternate settings by running the command with the -s flag:

myProjectCommand -s /path/to/different-settings.yaml

I now have the following objects I can pass to the rest of my package:

  • settings – a dictionary of all the settings read from the yaml config file
  • log – a logger setup with the settings found in the yaml config file
  • dbConn – a database connect setup with the settings found in the yaml config file


There are other usful trinkets within the code - read the docs to find out how to use them.

Command-Line Tools


Given a directory of MySQL scripts, mysqlSucker can execute the script files and process them according to their success or failure status.

Before you begin you will need to run the following code once to set a login-path for your mysql server:

mysql_config_editor set --login-path=<uniqueLoginName> --host=localhost --user=<myUsername> --password

This stores your credentials in an encrypted file located at ‘~/.mylogin.cnf’. Use mysql_config_editor print --all to see all of the login-paths set.


    mysqlSucker <pathToDirectory> <loginPath> <databaseName> [-s successRule -f failureRule]

    pathToDirectory       path to the directory containing the sql scripts to run (scripts must have `.sql` extension)
    loginPath             the local-path as set with `mysql_config_editor` (`mysqlSucker -h` for more details)
    databaseName          the name of the database to execute the scripts within

    -h, --help                                  show this help message
    -s successRule, --success successRule       what to do if script succeeds. Default *None* [None|delete|subFolderName]
    -f failureRule, --failure failureRule       what to do if script fails. Default *None* [None|delete|subFolderName]


To simply execute the scripts in a directory run:

mysqlSucker /path/to/scriptdir myLoginPath myDatabaseName

To delete script after thay have executed successfully:

mysqlSucker /path/to/scriptdir myLoginPath myDatabaseName -s delete

To move successful script to a passed sub-directory of /path/to/scriptdir and failed scripts to a failed sub-directory

mysqlSucker /path/to/scriptdir myLoginPath myDatabaseName -s pass -f failed


You may be thinking why would you ever need to dump the contents of a yaml file into a database. Well … IFTTT! With the IFTTT service you have quick and super easy access to the APIs of dozens of your favourite web-services. You can use any of the IFTTT channels as an input for an applet that then writes a yaml file with the data you wish to capture to a directory in your Dropbox account. Pointing yaml2db at this Dropbox directory in your filesystem then sucks all this lovely data into a MySQL database. It’s up to you then what you want to do with the data, the point is you now have a simple, homogenised way of pouring content from all those APIs into a local database.

You could grab the URLs for videos you ‘like’ on youtube or add to your watch-later list on vimeo. Or how about your sleep log from your fitbit, or a new contact added to your iOS device.

How about this applet that logs URLs moved into my instapaper read-work-projects folder:

So how does it work? yaml2db will take either a path to a single yaml file or to an entire directory of yaml files, parse the contents of those files and add the key-values to a mysql database. Here’s the usages statement (printed by typing yaml2db -h from a terminal window):

    yaml2db [-d] -s <pathToSettingsFile> <pathToYaml>
    yaml2db [-d] --host=<host> --user=<user> --passwd=<passwd> --dbName=<dbName> <pathToYaml>


    pathToYaml            path to a single yaml file or directory of yaml files
    pathToSettingsFile    path to a settings file with logging and database information (yaml file)
    --host=<host>         the database host
    --user=<user>         database user
    --passwd=<passwd>     database user password
    --dbName=<dbName>     name of the database to add the table content to

    -d, --delete          delete yaml file(s) once added to datbase
    -h, --help            show this help message
    -s, --settings        path to a settings file with logging and database parameters

The yaml files require a table value to indicate the name of the database table (or tables; comma-separated) to add the yaml key-values to. If the database tables do not exist, yaml2db will create them for you. Here’s an example of the content of a yaml file:

title: Why you should do most of your text editing in : Sublime Text | Sublime Text Tips
kind: webpage
subtype: article
table: web_articles,podcasts

yaml2db will take the content of this file and add it to both a web_articles and podcasts table.

To execute yaml2db on a single yaml file run:

yaml2db -d --host=localhost --user=username --passwd=mypassword --dbName=myGreatDatabase /Users/Me/yaml/20161219105124.yaml

Obviously replace the database parameters with your own. The -d flag indicates that you want to delete the yaml file once it’s been parsed.

To run yaml2db on an entire directory of yaml files run:

yaml2db -s /Users/Me/mydefault_settings.yaml /Users/Me/yaml/

where /Users/Me/mydefault_settings.yaml contains my database and logging parameters (see example at the start of this tutorial).


The sqlite2mysql tool does exactly what you would expect it to do; it takes the path to a sqlite database file and copies the tables found in the database to a MySQL database of your choosing.

For the usage run sqlite2mysql -h from the command-line:

Take a sqlite database file and copy the tables within it to a MySQL database

    sqlite2mysql -s <pathToSettingsFile> <pathToSqliteDB> [<tablePrefix>]


    pathToSqliteDB        path to the sqlite database file
    tablePrefix           a string to prefix the table names when copying to mysql database
    pathToSettingsFile    path to a settings file with logging and database information (yaml file)

    -h, --help            show this help message
    -v, --version         show version
    -s, --settings        the settings file

As usual pathToSettingsFile contains your MySQL database settings (see example at the start of this tutorial). To convert a sqlite databse I could run something like:

sqlite2mysql -s /Users/Me/mydefault_settings.yaml /Users/Me/ebooks.sqlite imported

This command takes the tables in the /Users/Me/ebooks.sqlite database, prepends the names of the tables with ‘imported_’ and imports the tables into the MySQL database whose settings are found in the /Users/Me/mydefault_settings.yaml file. Here are the resulting MySQL database tables as listed in MySQLWorkbench:

imported tables in MySQL database
