- h1. Slide Show (S9) Code Syntax Highlighting
-
- The slideshow (S9) gem now includes the Ultraviolet (Uv) gem that lets you use/turn on
- experimental syntax highlighting in your slides for your code. Add @#!ruby@ after
- the code block. Example:
-
- {{{{{{
- #!ruby
- puts "Syntaxes:"
- puts Uv.syntaxes.join( ", " )
-
- puts "Themes:"
- puts Uv.themes.join( ", " )
- }}}}}}
-
- Or use any of the other 40+ languages supported by Ultraviolet. Use headers to select any of the 20+ Ultraviolet syntax highlighting themes[1] and/or turn off line numbering. Example:
-
- {{{
- code-theme: blackboard
- code-line-numbers: false
- }}}
-
- fn1. active4d, all-hallows-eve, amy, blackboard, cobalt, dawn, eiffel, espresso-libre, idle, iplastic, lazy,
- mac-classic, pastels-on-dark, slush-poppies, spacecadet, sunburst, twilight, zenburnesque

- Refactoring:
-
- {{{
- #!ruby
- def highlight_text(input, words_to_highlight=%w(important monkey dancing))
- input.gsub(/#{words_to_highlight.join('|')}/i, '*\0*')
- end
-
- puts highlight_text("Hey monkey, it's important you start dancing right now!")
- # >> Hey *monkey*, it's *important* you start *dancing* right now!
- }}}
-
-
- Another Refactoring:
-
-
- {{{
- #!ruby
- class String
- def highlight(words=[])
- words.empty? ? self : self.gsub(Regexp.union(*words), '*\0*')
- end
- end
-
- puts "I think it's important to have a dancing monkey in your bedroom.".highlight %w(important monkey dancing)
- # => I think it's *important* to have a *dancing* *monkey* in your bedroom.
