Instance Method Details

#escaped_text ⇒ Object

By default, no escaped text

# File 'app/models/chunks/wiki.rb', line 14

def escaped_text() nil end

#mask(content) ⇒ Object

Delimit the link text with markers to replace later unless the word is escaped. In that case, just return the link text



18
 
# File 'app/models/chunks/wiki.rb', line 18

def mask(content) escaped_text || pre_mask + link_text + post_mask end

#regexp ⇒ Object 



20
 
# File 'app/models/chunks/wiki.rb', line 20

def regexp() Regexp.new(pre_mask + '(.*)?' + post_mask) end

#revert(content) ⇒ Object 



22
 
# File 'app/models/chunks/wiki.rb', line 22

def revert(content) content.sub!(regexp, text) end

#unmask(content) ⇒ Object

Do not keep this chunk if it is escaped. Otherwise, pass the link procedure a page_name and link_text and get back a string of HTML to replace the mask with.
