Carrom tournaments management
|Author:||Lele Gaifax <firstname.lastname@example.org>|
This project contains some tools that make it easier the organization of a championship of Carrom tournaments using either a variant of the Swiss system, the Knockout system or even everyone against everyone events.
The main component is a Pyramid application serving two distinct user interfaces:
- A very light, HTML only, read only view of the whole database, where you can actually browse thru the clubs, championships, tourneys, players and ratings. You can see it in action on the public SoL instance at https://sol4.metapensiero.it/lit/.
- A complete ExtJS based desktop-like application, that exposes all the functionalities described below in an easy to manage interface.
SoL requires Python 3, it does not work with Python 2
These are the key points:
Scarry spoke only Italian, because the i18n mechanism in Delphi (and in general under Windows) sucks. Most of the code was written and commented in Italian too, and that made it very difficult to get foreign contributions.
There is a super user (named “admin” by default) that can do everything, in particular create other normal users, who can then log in and manage her own tournaments, but can’t change information owned by other users.
SoL 4 also implements an optional self registration procedure.
Scarry used Paradox tables, but we are in the third millennium, now: SoL uses a real, even if simple and light, SQL database under its skin.
Easy to use
The application is usually driven by computer-illiterated guys, so little to no surprises.
Easy to deploy
Gods know how many hours went in building f*cking installers with BDE goodies!
Bring back the fun
Programming in Python is just that, since the beginning!
The application implements the following features:
- basic tables editing, like adding a new player, opening a new championship, manually tweaking the scores, and so on;
- handle a single tourney
- compose a list of competitors: usually this is just a single player, but there are two people in doubles, or more (teams)
- set up the first round, made up of matches, each pairing two distinct competitors: if the tournament is associated with a rating this considers the Glicko2 rate of each player, otherwise uses a random pairing; either way, the tournament secretary is able to manually change the combinations
- print the game sheets, where the player will write the scores
- possibly show a countdown, to alert the end of the game
- insert the score of each match
- compute the new ranking
- print the current ranking
- possibly offer a way to withdraw some competitors, or to add a new competitor
- compute the next round
- repeat steps c. thru i. usually up to seven rounds
- possibly offer a way to go back, delete last round, correct a score and repeat
- if required, play up to three final rounds between the first two competitors
- recompute the ranking, assigning prizes
- update the rating the tournament is associated to
- handle a championship of tourneys
- each tourney is associated to one championship
- print the championship ranking
- data exchange, to import/export whole tourneys in a portable way
The very first requirement to install an instance of SoL on your own machine is getting Python 3.6 or better. This step obviously depends on the operating system you are using: on most GNU/Linux distributions it is already available, for example on Debian and derivatives like Ubuntu the following command will do the task:
$ apt-get install python3
Another recommended, although optional, add-on is the DejaVu fonts set, to support a rather wide range of glyphs when producing the PDFs printouts. As usual, on GNU/Linux it’s a matter of executing the following command
$ apt-get install fonts-dejavu
or equivalent for your distribution, while on M$-Windows you need to download them and extract the archive in the right location which usually is C:\Windows\Fonts.
Install SoL using pip:
pip install SoL
that will download the latest version of SoL from PyPI and all its dependencies as well
Install ExtJS 4.2.1:
python3 -m metapensiero.extjs.desktop
Create a standard config file:
soladmin create-config config.ini
and edit it as appropriate; you can also directly specify the name and the password of the super user (by default the name is admin and the password will be asked interactively):
soladmin create-config --admin differentone --password str4nge
Setup the database:
soladmin initialize-db config.ini
Load official data:
soladmin restore config.ini
Run the application server:
or, for poor Window$ users or just because using Python makes you happier:
python -m webbrowser http://localhost:6996/
This is a work-in-progress facility: better documentation and helper tools are on the way! It targets brave souls willing to face a bleeding edge experience.
Current state is based on the work contributed by Amar Sanakal, thank you!
Another option, if you have a 64bit computer, is to run the pre-built Docker image.
First of all, you must enable the hardware virtualization in the BIOS of your computer.
After you have tested the install in the Docker Quickstart terminal (for example as depicted here), run the following command in the same window:
docker run -d -p 80:6996 --name sol amarsanakal/solista
This will start the software and is now accessible on port 80. You can access it as http://<ip-address>.
The <ip-address> is the ip address of the docker machine running on your PC. This would have been displayed to you when you launched the Docker Quickstart terminal. You can check it anytime by running:
the ip address is shown under the URL column. Use that without the port number shown there. See https://docs.docker.com/machine/get-started/ for more details.
If you are a developer and want to play with Docker, you can checkout SoL sources and
- build an image with make docker-build
- change the admin credentials with make docker-change-admin
- start SoL within a Docker container with make docker-start, then visit http://localhost:6996/ as usual
See Makefile.docker for other related targets.
- Provide some Unix shell scripts and Windows batch files to make the end users happier
- Complete this section
- Figure out how to build a new image on hub.docker.com whenever a new SoL release happens
The complete sources can be downloaded with the following command:
git clone https://gitlab.com/metapensiero/SoL.git
I recommend using a virtual environment to keep you isolated from the system packages:
python3 -m venv env source env/bin/activate
After that, you can setup a development environment by executing the command:
pip install -r requirements/development.txt
You must then install the required ExtJS 4 sources executing:
python -m metapensiero.extjs.desktop --src
If you are a developer, you are encouraged to create your own fork of the software and possibly open a pull request: I will happily merge your changes!
You can run the tests suite with either
or with a more specific
Currently SoL is translated in English, French and Italian. If you know other languages and want to contribute, the easiest way to create a new translation is to create an account on the Weblate site and follow its translators guide.
Otherwise if like me you prefer using more traditional tools you can extract a copy of the sources and operate directly on the local catalogs under the directory src/sol/locale.
To extract translatable messages use the following command:
To check your work you must compile them with:
If you run in troubles, or want to suggest something, or simply a desire of saying “Thank you” raises up, feel free to contact me via email as lele at metapensiero dot it.
Consider also joining the dedicated mailing list where you can get in contact with other users of the application. There is also an issues tracker where you can open a new tickets about bugs or enhancements.
|||As of this writing I’m using version 3.7.0 and I’d recommend using that, but SoL used to work great with any version higher than 3.4.|
|||In fact it may even be already installed!|
|||The are actually two distinct catalogs, to take into account US and UK variants.|
|||GNU Emacs comes to mind of course, but there are zillions of them: start looking at the gettext page on Wikipedia.|
