Welcome to another edition of This Week in #dev, a series of posts where we bring some of our most interesting Slack conversations to the public. Let’s get to it!
Text Alignment in Markdown Tables
Neil Carvalho discovered that Markdown tables can support text alignment. By using a leading or trailing colon, you can indicate left, right, or center alignment.
| Country | Population |
| ------------- | ------------: |
| China | 1,371,220,000 |
| India | 1,296,834,042 |
| United States | 329,256,465 |
The above table will render as:
| Country | Population |
|---|---|
| China | 1,371,220,000 |
| India | 1,296,834,042 |
| United States | 329,256,465 |
Need Country Information? Ruby’s Got You Covered
Matheus Richard recommends the countries gem for obtaining various information about countries. The gem includes details such as the country local name, currency, spoken languages, subdivisions, and timezones.
Repeating Commands in ZSH
Neil also shares how to easily repeat the same command multiple times in zsh.
repeat TIMES { command }
So, for example, if you wanted to run a test 10 times, you could do:
repeat 10 { bin/rspec spec/system/my_spec.rb }
Louis also points out that if you want to save the output to a file, but
also watch it in real-time, you can use tee`:
repeat 10 { bin/rspec spec/system/my_spec.rb } | tee somefilename.txt
