How do I format outputted text?

How can I control the format (font size, color and location) for text
that I am out-putting to the screen. For example:

puts (“Ruby is great!”)

How can I make this appear in larger font on my screen when I run my
program?

Any help would be GREATLY appreciated!!

you could just put it in all capitals

Command Prompts don’t generally support multiple fonts on screen, it
basically
emulates a TTY < http://en.wikipedia.org/wiki/Teletypewriter >. You can
change
what font your command prompt displays stuff in, but your program can
not
really do it for you the way you intend for it to do so.

Most Command Line Interfaces can support colours and bold text -> but
doing
that is not very portable. Typically it involves using the curses
library
(which tries to make such things portable between UNIX systems) or
DOS/Windows
API instructions (only portable between those systems). Other Operating
System
families would have their own way of doing it.

Doing such things as displaying the things in multiple fonts, sizes,
colours,
styles e.t.c. can be done by creating a GUI program instead of a console
one,
or even a Web Application with Ruby on Rails.

Are you using a GUI toolkit?
A: No, I don’t even know what one is. I am new to both programming and
Ruby.

A GUI (Graphical User Interface) toolkit is a collection of code that
makes it
easier to write a program that runs within a ‘Window’ on your screen,
like how
most programs do (notepad, internet explorer, word, e.t.c.).

Without a GUI toolkit, every one would have to write the code to create
a
‘window’ on screen them selves and they’d never look the same… Like
how
Programmers used to have to write their own puts() methods if they
wanted to
put stuff to the command prompt :S

Are you just printing to the console?
A: Yes, I am just printing to the console.

Are you (trying) to get this functionality in TextMate?
A: I am not familiar with TextMate.

TextMate is a feature full text editor for Mac OS X popular with
programmers.

What operating system are you using?
A: Windows XP

Do you need a portable program?
A: Yes, I would prefer that it be portable.

Basic input/output to and from the system console is usually pretty
portable
in most high level languages created since the 1970s / 1980s. Some
things are
not but simple stuff l

This link is very valuable

Thanks for the help!

We are all new once, most regular people are to young to know every
thing
about computers and even the oldest geeks probably have yet to learn it
all.

As you learn more, you’ll grow deeper in the force. Learning to ask
questions
that make it easier for people to help you, will increase your chances
of
success… Rather then meeting up with a few people that have probably
yet to
stop laughing at a beginners question and hopefully not post remarks =/

PS: No offense to any of the other people on this mailing list with that
last
sentence.

A: Yes, I am just printing to the console.

When printing to the console, the simplest case is that you add spaces
or newlines.

10.times { puts }
puts (" " * 20) + “This is in the middle of the screen”
10.times { puts }

Being that most text mode programs print one line at a time, there isn’t
an easier way. Perhaps you could write a method that printed 30 lines at
a time, if you wanted the illusion of being able to print to various
parts of the screen. A lot of people use simple ideas like printing
blank lines or loud characters to get the eye’s attention. You can’t
change the font, but there’s a lot you can do to effectively
communicate. Some examples:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

!!! Are you sure? !!!

To do more with screen positioning, there is a library called ncurses
that gives you complete flexibility to place anything anywhere on the
screen. This is really the standard for complex console output. The
homepage for ncurses-ruby is here: http://ncurses-ruby.berlios.de/ , and
I saw what looked like a Windows package, but I don’t know whether that
means you can install it without cygwin (Linux emulation, basically).
Learning to use this library might be too much to learn at once for a
beginner to programming, but know that this is the most powerful tool
(that can be used with Ruby) for doing layout stuff on the console.

If you will be content with being able to change colors, I would go for
a library called HighLine (http://highline.rubyforge.org/). See the
examples here
http://viewvc.rubyforge.mmmultiworks.com/cgi/viewvc.cgi/trunk/highline/examples/?root=highline
for descriptions of how it can be used. You can find documentation from
the first link.

Good luck,
Dan

Or you could use WideStudio [1] to make Ruby based executable programs
in a GUI style!

Doing it in console, you can’t format it. There are GUI toolkits like
FXRuby you can checkout or just do a google search for GUI toolkits for
Ruby. If you do Rails development on MacOSX there is a gem that allows
you to have your text in different colors for your log file. Being new
to all this stuff, that may be a bit too much, but just keep it in mind
if you ever get into Rails development, then hop back on here and ask
the question again :slight_smile:
