undefined method `matches` for #<Jekyll::Converters::Markdown:0x00000001d9e4e0> (NoMethodError)

[lingnand]

I'm using a Octopress+Jekyll setup and placed pandoc.rb under <web-directory>/plugins; I've changed _config.yml as suggested in readme.md.

But as soon as I run jekyll build I get the following

[fauno]

hmmm have you tried with a newer jekyll? i don't remember which version we were using when we started but now we're on jekyll 1.0+

[mauriciopasquier]

It works with jekyll 1.0.0 here.. haven't tried with an older version.

[lingnand]

mhh I'm using it with Octopress and Octopress is using a jekyll of version 0.12 and that might be where the problem comes from. Tried to tell Octopress to use a higher version, but that would break the whole thing. Guess this plugin is not compatible with Octopress...

[mauriciopasquier]

It seems so... Octopress' tasks use jekyll's old switch style instead of subcommands. Maybe it's easy to patch it, maybe not.

Anyway, I think I can make this plugin backwards compatible..

[mauriciopasquier]

@lynnard please test again with branch 'fix-3' from this repo.

[lingnand]

Thanks for your effort! There're still some issues though.

[mauriciopasquier]

At least now it's in the Generator and not the Converter :P

Are you sure you have a pandoc key in _/home/lingnan/Dropbox/lynnard.github.com/_config.yml? Could you shows that file?

[lingnand]

Somehow I thought it would be a good idea to test without my config changed first, so all the previous error info is in fact produced by calling rake generate just after placing the pandoc.rb in my plugins directory.

After making the necessary changes to _config.yml there pops an entire different list of errors

I think it throws that error when it can't find a file. So that means your old jekyll did find the plugin this time :)

Do you have that ref.bib file that is configured here?

flags: '--smart --bibliography=ref.bib'

If not, remove the --bibliography option and try again, please. If that doesn't solve it, I've had some troubles with non-default (by jekyll standards) source, layouts and plugins locations. Maybe it's that.

[fauno]

pandoc --smart --bibliography=ref.bib -o pdf/blog/2013/07/30/the-very-first-blog-post/ --latex-engine=latex

the -o flag requires a file with the correct extension, it's being passed a directory. i think the problem is with permalinks now.

[fauno]

@lynnard could you try the hotfix/issue-3 branch?

[lingnand]

Mmh...Now is this

Hi, any update on this problem? I think I should as well look into the code myself, but I haven't got time to whip up my ruby skills.

[fauno]

hey! sorry to keep you waiting, could you try with a more modern jekyll? i just saw you're using 0.12

I use jekyll 2.2.0, and the error message like this:

@XiZepu i don't know why i don't get email notifications, sorry i never replied! :/

i think we fixed your issue a while ago, it had to do with excerpts being included on the yaml metadata but actually being a ruby object, so we skipped it
