First, RubyGems looks to see if the gem exists in the current directory (you can keep your own store of gems locally, if you like), and if not, it heads off to RubyForge to download the gem and install it from afar. Last, it builds the documentation for the library using rdoc (covered in 8), and installation is complete. This process is the same for nearly all gems.

Note In many cases, installing one gem requires other gems to be installed too. That is, the gem you re

of the entire slide in seconds, as in Ground Rule 1 The group process has broken the foundation of the BBP approach and rendered the slide ineffective Not only does breaking the BBP foundation impact an individual slide, but it also disrupts the sequence of slides It s easy to get lost in the individual slides instead of seeing the big picture of the story template For example, for BBP to work, you should have the same font style and size of headlines on all your slides to ensure that each slide is easy to read and links together visually Within the hierarchy levels of your storyboard, you should have consistent placement of headlines as each slide ows visually from one to the next.

value. (exec doesn t return anything because it is a statement itself.) For example, you can use the following to make a Python calculator: >>> eval(raw_input("Enter an arithmetic expression: ")) Enter an arithmetic expression: 6 + 18 * 2 42

trying to install might have other gems it needs to operate. If this is the case, gem will tell you, and will install the required gems in each case if you agree.

If you run gem list again at this point, your local list of gems will include the newly installed gem (in this case, feedtools).

You break the consistency in the BBP approach only for speci c reasons for example, when you disrupt the ow of ideas to indicate that the next idea is more important than the others, as determined by the story template But in this example, the organization broke the consistency for no reason the unnecessary details added to the headlines do nothing to help the big picture of the presentation, and instead hurt it The situation can get even worse if you start adding new slides to your storyboard and rearranging them without re ecting the changes in the story template Soon, the internal pacing and ow of the presentation begin to unravel too The graphical way to x the problems shown in Figure 8-6 is easy remove everything except the minimum visuals needed to illustrate the headline, as in the original slide (upper left).

As the RubyGems system isn t an integrated part of Ruby, it s necessary to tell your programs that you want to use and load gems. To demonstrate how gems can be used, you ll install the redcloth gem, a library that can convert specially formatted text into HTML, ready to be used on a Web page. Use gem install redcloth (or sudo gem install redcloth, if you aren t running as root or a superuser), as demonstrated earlier, to install the gem. Once the gem is installed, run irb or create a new Ruby source file, and use the redcloth gem like so:

Note The expression eval(raw_input(...)) is, in fact, equivalent to input(...).

require 'rubygems' require 'RedCloth' r = RedCloth.new("this is a *test* of _using RedCloth_") puts r.to_html

But the organizational x will take a bit more work People s urges to add extraneous detail are most often related to habit or myths, such as thinking that the more you add, the more people will learn; or that you need to add pizzazz to catch someone s attention; or that you need to entertain people instead of helping them learn To protect your hard-earned BBP foundation, stand rm on your research-based grounding from 2 as you help other people to understand that Less is more is more than a slogan it s a strategy and tactic for getting results in your presentations..
