clean_msg(text) click to toggle source

do whatever is required to commit message to get it clean and ready for imagemagick

# File lib/lolcommits/plugins/loltext.rb, line 55
def clean_msg(text)
  wrapped_text = word_wrap text
  escape_quotes wrapped_text
end
escape_quotes(text) click to toggle source

conversion for quotation marks to avoid shell interpretation does not seem to be a safe way to escape cross-platform?

# File lib/lolcommits/plugins/loltext.rb, line 62
def escape_quotes(text)
  text.gsub(/"/, "''")
end
word_wrap(text, col = 27) click to toggle source

convenience method for word wrapping based on github.com/cmdrkeene/memegen/blob/master/lib/meme_generator.rb

# File lib/lolcommits/plugins/loltext.rb, line 68
def word_wrap(text, col = 27)
  wrapped = text.gsub(/(.{1,#{col + 4}})(\s+|\Z)/, "\\1\n")
  wrapped.chomp!
