undefined method `markdown_engine' for Middleman::Application::MiddlemanApplication1:Class

[jashmenn]

Hey guys, I'm getting a really weird error trying to get middleman-syntax working.

Using a fresh middleman version 3.0.6.

In config.rb

activate :syntax
set :markdown_engine, :kramdown

In Gemfile

gem "middleman"
gem "kramdown"
gem "middleman-syntax"

Then running bundle exec middleman server gives:

I'm a missing something obvious? Thanks!

I'm getting the same error, middleman 3.0.5, middleman-sytax 1.2.0. However, I'm using

set markdown_engine, :redcarpet

[joshwlewis]

If you are still looking for a solution, switching my Gemfile version worked just fine.

gem "middleman-syntax", "= 1.1.1"

EDIT I take that back, only a few pages were fixed with that.

[jashmenn]

Thanks - that works if I use redcarpet.

I cannot gem install middleman-syntax -v 1.1.1on cygwin as posix-spawndoes not exists :(

Hi guys,

Could you try a couple things with the 1.2.0 version? First, try the newest middleman gem. 3.0.5 and 3.0.6 are very old. Second, try putting your set :markdown_engine statement before activate :syntax.

[bhollis]

@bardware pygments.rb requires posix-spawn, which is why I switched this gem to use rouge in 1.2.0.

[joshwlewis]

@bhollis I updated to 3.0.14 last night, and it is not working with middleman-syntax 1.2.0 (same error as above). The middleman init command gave me a Gemfile with 3.0.5 originally.

And yes, set :markdown_engine is at the top of config.rb where activate :syntax is at the bottom (just like in the generated version).

Sample app here -- joshwlewis/presentation just uncomment the activate :syntax line and run the server to get the error.

[bhollis]

OK, 1.2.1 is released that fixes this problem. This is what I get for only testing against Middleman's master branch.

[joshwlewis]

Thanks for the quick fix, works great!
