STDOUT text formatting

Quick and dirty

You can call class methods to print out single lines like this:

Formatador.display_line('Hello World')

You use tags, similar to html, to set formatting options:

Formatador.display_line('[green]Hello World[/]')

[/] resets everything to normal, colors are supported and [_color_] sets the background color.

Standard options

  • format - and adds color codes if STDOUT.tty? is true

  • display - calls format on the input and prints it

  • display_line - calls display, but adds on a newline (n)

  • redisplay - Displays text, prepended with r which will overwrite the last existing line

Extensions

  • display_table: takes an array of hashes. Each hash is a row, with the keys being the headers and values being the data. An optional second argument can specify which headers/columns to include and in what order they should appear.

  • redisplay_progressbar: takes the current and total values as its first two arguments and redisplays a progressbar (until current = total and then it display_lines). An optional third argument represents the start time and will add an elapsed time counter.

Indentation

By initializing a formatador object you can keep track of indentation:

formatador = Formatador.new
formatador.display_line('one level of indentation')
formatador.indent {
  formatador.display_line('two levels of indentation')
}
formatador.display_line('one level of indentation')
