Top Forums UNIX for Dummies Questions & Answers How to underline/bold and how to align output Post 75284 by jim mcnamara on Thursday 16th of June 2005 12:41:23 PM

If you want the output of wiriting the file to a terminal ( a tty device) to have bold text, etc: you embed ANSI escape sequences in the text to turn off/on bold, turn off/on underline, etc. When you see those sequences in an editor they look like junk characters, it only works on a display terminal.

DESCRIPTION

       This package provides symbolic names for the ANSI attribute control codes. For each control code a single command is provided which returns
       this code as its result. None of the commands of this package write  to	a  channel;  that  is  handled	by  higher  level  packages,  like
       term::ansi::send.

API

   INTROSPECTION
       ::term::ansi::code::attr::names
	      This command is for introspection. It returns as its result a list containing the names of all attribute commands.

       ::term::ansi::code::attr::import ?ns? ?arg...?
	      This  command imports some or all attribute commands into the namespace ns. This is by default the namespace attr. Note that this is
	      relative namespace name, placing the imported command into a child of the current namespace. By default all commands  are  imported,
	      this can howver be restricted by listing the names of the wanted commands after the namespace argument.
