Feature

  • easy to use method, control, for combination of tigetstr/tparm/tputs

  • low-level terminfo binding (setupterm, tigetflag, tigetnum, tigetstr, tparm, tputs)

  • TIOCGWINSZ/TIOCSWINSZ ioctl for screen size

  • ctermid to avoid hardcoding /dev/tty

  • wcswidth to measure a string width in number of columns

Usage

easy to use methods

require 'terminfo'
TermInfo.control("cuf", 7)    # cursor forward 7 columns
p TermInfo.screen_size        # use TIOCGWINSZ, LINES/COLUMNS env. or terminfo lines#/cols#

low level methods

require 'terminfo'
t = TermInfo.new(ENV["TERM"], File.open(TermInfo.ctermid, "r+"))
print t.tputs(t.tparm(t.tigetstr("cuf"), 7), 1)  # cursor forward 7 columns
p TermInfo.tiocgwinsz(STDOUT)                    # use TIOCGWINSZ
