Section numbering option in to_latex
Reported by emime | March 3rd, 2009 @ 11:19 AM
Hello,
Latex supports numbered and unnumbered sections, but to_latex use only unnumbered (that is section* environment).
I would like to add an option to enable section numbering.
What I did to make the thing works...
In textile_doc.rb I added the following attribute:
attr_accessor :latex_numbering
Then in latex.rb I edited the things as follows (starts from line 26):
# headers
{ :h1 => (:latex_numbering) ? 'section' : 'section*',
:h2 => (:latex_numbering) ? 'subsection' : 'subsection*',
:h3 => (:latex_numbering) ? 'subsubsection' : 'subsection*',
...
Then, in my test.rb what I need to do is only to set the option as follows:
latex = RedCloth.new(mytextile,[:latex_numbering]).to_latex.to_s
Is it the right way to manage new options? I would like to submit a patch about.
Thanks a lot, Emi

Hello, I'm sorry...but really the code does not work...
Actually, with the code above, the to_latex method uses always section (without underscore).
I tried also this: @@@ doctt = RedCloth.new(mytextile) doctt.latex_numbering = false latex = doctt.to_latex.to_s@@@
I guess something is wrong ...don't know wath...please help.

Hello, be patient, I told I'm newbie...
Here a possible solution (that works!!)...I need to check the latex_numbering attribute during the headers definition as follows:
# headers { :h1 => 'section*', :h2 => 'subsection*', :h3 => 'subsubsection*', :h4 => 'textbf', :h5 => 'textbf', :h6 => 'textbf', }.each do |m,tag| define_method(m) do |opts| #check numbering option if latex_numbering then tag=tag.delete('*') end "\\#{tag}{#{opts[:text]}}\n\n" end end
Now the following will work correctly:
latex = RedCloth.new(textile) latex.latex_numbering = false latex = latex.to_latex.to_s
I don't know if it's the right way...but works

I would vote to avoid using the starred versions altogether and let the surrounding LaTeX environment control section numbering via LaTeX's secnumdepth counter, e.g., \setcounter{secnumdepth}{-1} will turn off all section numbering whereas \setcounter{secnumdepth}{2} (LaTeX's default) will only number down to level 2 headings (subsections).

- Title changed from Equation numbering option in to_latex to Section numbering option in to_latex
To align title with contents, renamed "Equation numbering" to "Section numbering".

You are true. \setcounter can be placed in the preamble file and this way numbering is left to a document 'design' decision.
I complain also about h4, h5 and so....why use \textbf?
Finally, we can use the following:
# headers { :h1 => 'section', :h2 => 'subsection', :h3 => 'subsubsection', :h4 => 'paragraph', :h5 => 'subparapgraph', :h6 => 'textbf', }.each do |m,tag| define_method(m) do |opts| "\\#{tag}{#{opts[:text]}}\n\n" end end
To align title with contents ops...

I see from the code that "the starred way" was left. Is this compatible with secnumdepth counter? Otherwise please remove the stars.
Cheers Emi

I followed the link before...this latest one shows me the correct code.
Thanks Emi
