Various utilities for database and config files use. Text to Pdf converter

Project description


tecutils provides various utilities to accelerate development
of programs design to use MySQL as a database and substitute
the use of global variables.
Also includes a standalone module to tranform a text file to pdf.

tecutils contains the following modules:

- mydb
- envvar
- simplecrypt
- txt2pdf


mysql-python (sudo apt-get install python-mysqldb)

There are three functions that take care the database interaction:

- GetRecordset(sHost,sUser,sPwd,sDB,sSQL)
- GetData(sHost,sUser,sPwd,sDB,sSQL)
- ExecuteSQL(sHost,sUser,sPwd,sDB,sSQL)::

from tecutils.mydb import ExecuteSQL, GetData, GetRecordset

myHost = "localhost"
myUser = "root"
myPwd = "password"
myDB = "test"

ExecuteSQL(myHost, myUser, myPwd, myDB, "INSERT INTO animal (name, category) VALUES " + \
('snake', 'reptile'), ('frog', 'amphibian'), ('tuna', 'fish'), ('racoon', 'mammal'),
('lizard', 'reptile')")

sql="SELECT name FROM animal WHERE category='reptile'"
GetRecordset(myHost, myUser, myPwd, myDB,sql)

sql="SELECT name FROM animal WHERE category='%s'" % thistype
GetData(myHost, myUser, myPwd, myDB,sql)


Reads a file containing <var>=<value> and loads in a container, so you can use container.var



from tecutils import getVarFromFile
db = getVarFromFile('config/db.cfg','db')


If use the two modules provides a way to use a configuration file to access de database::

# this is the config file:
# db.cfg
HOST = 'localhost'
USER = 'root'
PWD = 'password'
DB = 'test'

and use it in a program::

from tecutils.envvar import getVarFromFile
from tecutils.mydb import GetRecordset


data = GetRecordset(db.HOST,db.USER,db.PWD,db.DB,"SELECT * FROM animal")
for animal in data:
print animal[0]


Many thanks to the Dabo team: Ed Leafe and Paul McNett (
for this simple utility to "obscure" passwords so casual browsing on the database
connection info doesn't show the real one.


from tecutils.simplecrypt import simplecrypt
pwd = 'foobar'
crypt = SimpleCrypt()
pwd = crypt.encrypt(pwd)

or using the example from envvars::

crypt = SimpleCrypt()
db.PWD = crypt.decrypt(db.PWD)


requires reportlab and pyPDF for normal use
for windows printing requires win32api or ghostscript and ghostview

Usage: [options] text_file
The name of the outfile is the name on the text_file with pdf extension.

-h, --help show this help message and exit
-c COPIES, --copies=COPIES
number of copies, only valid with -p option
-g print through ghostprint, only valid with -w option
-m use half letter as size of output, default letter
--output=OUTPUT use specific output file name
-p, --print print file after converting
--printer=PRINTER printer to send file, default: send to default printer
-w use win32api to send file to print, only valid with -p
