Instance Method Details

# File 'lib/polytexnic/postprocessors/polytex.rb', line 46

def escape_hack(string)
  string.gsub('\\', '\\\\\\')
end

#fix_verbatim_bug ⇒ Object

Fixes a kramdown verbatim bug. When converting code, kramdown outputs “beginHtml#verbatimfoo” instead of “beginHtml#verbatimnfoo”.

# File 'lib/polytexnic/postprocessors/polytex.rb', line 18

def fix_verbatim_bug
  @source.gsub!(/\\begin\{verbatim\}/) { |s| s + "\n" }
end

#remove_hypertarget ⇒ Object

Removes references to the hypertarget package. TODO: Support hypertarget This isn’t a priority, as you get most of what you need with hyperref.

# File 'lib/polytexnic/postprocessors/polytex.rb', line 10

def remove_hypertarget
  @source.gsub!(/\\hypertarget.*$/, '')
end

#write_polytex_code ⇒ Object

Writes the PolyTeX code environments based on the code cache. I.e., code that looks like lang=“ruby”

def foo
  "bar"
end

becomes %= lang:ruby beginHtml#code def foo

"bar"

end endHtml#code which reduces syntax highlighting to a previously solved problem.
