# tRandom
|
||||
# tRandom v0.4.2
|
||||
|
||||
A simple GUI random number generator written in Python.
|
||||
tRandom is a simple, cross-platform, psuedo-random number generator for games and draws. Written in Python using tkinter.
|
||||

||||
# License
|
||||
|
||||
Distrubuted under the GPLv3 license.
|
||||
|
||||
# About
|
||||
|
||||
I created tRandom while a Python beginner, I was attempting to gain experience and create my first GUI application. Here it is to share for all.
|
||||
|
||||
# Installing
|
||||
|
||||
A deb package is available for v0.4.1 with two minor know issues. This has only been tested on Ubuntu 18.04, but being a 100% Python application with only included packages imported, it should run happily all over the place.
|
||||
|
||||
To install elsewhere, the `tRandom.py` and `icon.png` files should be kept in the same folder, as long as you have the dependencies listed below installed, you will be able to launch the `tRandom.py` file directly. On Windows devices you may want to rename the `py` file to `tRandom.pyw` which will launch the program without a console window opening.
|
||||
|
||||
# Dependencies
|
||||
|
||||
If installing using the deb package all dependencies should be taken care of.
|
||||
|
||||
- `python3` (Tested on 3.8)
|
||||
- `python3-tk`
|
||||
|
||||
# Known Issues
|
||||
|
||||
- When installing with the DEB, the package will show in the `Lost & Found` category in your app launcher (At least on KDE Plasma).
