# ActionView Text Helpers are great!
|
||
|
|
# Let's extend the String class to allow us to call
|
||
|
|
# some of these methods directly on a String.
|
||
|
|
# Note:
|
||
|
|
# - cycle-related methods are not included
|
||
|
|
# - concat is not included
|
||
|
|
# - pluralize is not included because it is in
|
||
|
|
# ActiveSupport String extensions already
|
||
|
|
# (though they differ).
|
||
|
|
# - markdown requires BlueCloth
|
||
|
|
# - textilize methods require RedCloth
|
||
|
|
# Example:
|
||
|
|
# "<b>coolness</b>".strip_tags -> "coolness"
|
||
|
|
