Um script que manda um e-mail quando há um campeonato novo na WCA. A script which send an e-mail when there's a new WCA competition. Integrates the WCA's and the Google Sheets API, the subscription is made by the Google Forms.

"The World Cube Association governs competitions for mechanical puzzles that are operated by twisting groups of pieces, commonly known as 'twisty puzzles'. The most famous of these puzzles is the Rubik's Cube, invented by professor Rubik from Hungary. A selection of these puzzles are chosen as official events of the WCA. As the WCA has evolved over the past decade, over 100,000 people have competed in our competitions."

Me and my friends have the speedcubing as a hobbie, simplified: solve rubik's cube and other puzzles in the lowest time as possible. There's official competitions all over the world, realized by the World Cube Association (WCA), as above-mentioned.

We participate in them, and is very common we check the WCA's site searching for nearly competitions. Sometimes, we check few times a week, and nothing; sometimes, we forgot to check and lost a long-awaited competition. To solve this issue, I had the idea of making a script that would check the site periodically and notify us when it identified a competition nearby that could be of interest to us.

Subscribe, inserting your name, email, language and the city you want to be notified by filling the form bellow:

To execute this project, I've initially used Python with the libraries requests and BeautifulSoup for web scrapping in the site itself and smtplib for sending emails. But I made a migration to Golang, with the WCA's API instead of the front-end site. I studied modulation of code in local packages, the usage of libraries as spreadsheet for connect with Google Sheets API and the gomail to send the notifications.

The code works as follows:

• Fetch the data from a spreadsheet in my Google account (recipients data and credentials to emails sending);
• Verify the upcoming competitions of each recipient city;
• Update it in the spreadsheet;
• Compare the current verification with the last one;
• Send an email if this numbers are different;

All this process is logged in main.log file.

In my Google account, the spreadsheet is organized in this format:

The data provided by the form and the past verifications.

My personal friends who agreed to be beta testers. When the code is in development it runs here first.

The email and password of the email sender account.

• Add an runtime map with {city : upcoming copetitions} and if the city were already verificated in other recipient, do not verificate again and catch this data from the map.
• Add tests in the whole app.

Suggest something to do in issues :)
