Question 1

How do I create a colored progress bar with Formatador in Ruby?

Accepted Answer

Instantiate Formatador::ProgressBar with total and color options, then increment it. For example, `progress = Formatador::ProgressBar.new(100, :color => 'light_blue')` and call `progress.increment` in a loop to update dynamically.

Question 2

Formatador vs Colorize – which is better for terminal colors?

Accepted Answer

Formatador offers a tag-based syntax and extra utilities like tables and progress bars, while Colorize focuses solely on method chains for colors. Choose Formatador for all-in-one formatting, Colorize for minimal color-only needs.

Question 3

Can Formatador handle nested data in tables?

Accepted Answer

Yes, use dot notation in the column array to access nested keys. For example, `Formatador.display_table(data, [:name, :'meal.drink'])` will flatten nested hashes into table columns, as shown in the README.

Question 4

How to strip color codes from Formatador output for logging?

Accepted Answer

Formatador adds color codes only if STDOUT.tty? is true. For logging, call the format method directly to get raw text without display, or manually remove ANSI sequences using string processing libraries.

Question 5

Is Formatador still maintained? Last update was 2022.

Accepted Answer

The library appears stable with infrequent updates; check the GitHub repository for recent activity or issues. It's likely reliable for basic use but may lack support for newer Ruby versions or features.

Question 6

How to customize table headers in Formatador?

Accepted Answer

Specify headers in the second argument array when calling display_table. The order and keys define the headers, and you can use symbols or strings, but customization is limited to column selection without advanced styling.
