How to disable line numbers on specific code block?

[tuomasj]

Hi,

Is there a way to disable line numbers on specific code block? Generally, I want to have line numbers on my code blocks but there are occasions where I would like to disable line numbers on specific code block.

I'm using markdown with fenced code blocks.

# config.rb
set :markdown, :fenced_code_blocks => true, :smartypants => true

This is a markdown code block with ruby with line numbers, just for an example:

```ruby
# hello.rb
def hello
  puts "hello"
end

The end result is a code block with line numbers:

``` ruby
1  # hello.rb
2  def hello
3    puts "hello"
4  end

This is a markdown code block where I would like to disable line numbers:

This is just an imaginary example, there is no nolinenumbers syntax.

```nolinenumbers
middleman init MY_PROJECT
bundle exec middleman serve

The end result would be a code block without line numbers:

middleman init MY_PROJECT bundle exec middleman serve

Is there an option or parameter that would handle this?

Not in markdown, no. If you use the code helper in another template language, you can pass parameters.

Here is an experiment that I tried: https://github.com/tuomasj/middleman-syntax/blob/no_linenumbers_experiment/lib/middleman-syntax/highlighter.rb#L8

This is not the way this "problem" should be fixed for production, but since I'm the only one using, this will do for me :smile:

So, now I have a syntax called "plain":

```plain
puts "Look ma, no line numbers!"

Actually...

Try this:

```ruby?line_numbers=false
puts "Look ma, no line numbers!"

Hey - I tried ?line_numbers=false but line numbers were still present. Anything else you advise?

relevant config.rb:

set :markdown_engine, :redcarpet
set :markdown, :fenced_code_blocks => true, :smartypants => true
activate :syntax, :line_numbers => true

versions: middleman: (3.3.12) middleman-blog: (3.5.3) middleman-syntax: (2.1.0) redcarpet (3.3.4)

[bhollis]

Yeah, looks like we'd need to make some changes for that to work.

[tuomasj]

```ruby?line_numbers=false
puts "Look ma, no line numbers parameter is working now!"

Here is the commit for working version with Redcarpet: https://github.com/tuomasj/middleman-syntax/commit/3d19e5b544648eddf86ae27324fa7fc1a2edba4a

When using redcarpet this language parameter approach works, but Kramdown handles the language parameter differently. Any suggestions what would be the best approach?

[bhollis]

Neat! Wanna send a PR? I'm not sure Kramdown will make this available.

[tuomasj]

Yeah, I'll send it as soon as I remove all Kramdown releated stuff
