undefined method `matches` for #<Jekyll::Converters::Markdown:0x00000001d9e4e0> (NoMethodError) #3

lingnand · 2013-07-30T07:00:21Z

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

The text was updated successfully, but these errors were encountered:

fauno · 2013-07-30T16:11:40Z

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 · 2013-07-30T18:03:07Z

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

lingnand · 2013-07-31T06:20:50Z

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 · 2013-07-31T17:02:00Z

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 · 2013-07-31T18:05:29Z

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

lingnand · 2013-07-31T19:00:39Z

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

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 · 2013-07-31T19:59:06Z

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 · 2013-08-16T11:48:16Z

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 · 2013-08-16T18:06:04Z

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

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.

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

@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
