undefined method each for path

[HoffiMuc]

ruby: 3.2.2
jekyll 3.9.3

bundle info jekyll-drawio

• jekyll-drawio (1.1.0)

on doing (in my markdown file):

{% drawio path="/assets/drawio/arch/Arch_Overview.drawio" page_number=0 height=400 %}

I get:

  Liquid Exception: undefined method `each' for "path=\"/assets/drawio/arch/Arch_Overview.drawio\" page_number=0 height=400 ":String in dev/arch/Arch_0_Overview.md
bundler: failed to load command: jekyll (/Users/hoffi/.gem/ruby/3.2.2/bin/jekyll)

    variables.each do |variable|

any ideas?

Hi @HoffiMuc,

Thank you for highlighting this issue.
So far, it looks like a problem related to the parsing of variables.

Fixed, will be released as part of 1.1.1

sorry to disturb again, but I still don't get it to fly with v1.1.1:

my jekyll project is in subfolder docs/ of my gitproject.

so my filesystem locations for Jekyll are:

• <PRJROOT>/docs/Gemfile
• <PRJROOT>/docs/_config.yml
• <PRJROOT>/docs/assets/...
• <PRJROOT>/docs/dev/arch/....md

the markdown file in which I want to render the drawio image is: <PRJROOT>/docs/dev/arch/Arch_0_Overview.md

in there I have

{% drawio path="/assets/arch/drawio/Arch_Overview.drawio" page_number=0 height=400 %}

/Users/hoffi/.gem/ruby/3.2.2/gems/jekyll-drawio-1.1.1/lib/diagram_extractor.rb:6:in `initialize':

explicityly:

any ideas?

[mutcher]

Long story short. Use a relative path instead of an absolute.

The plugin works only with relative paths so far. I didn't find a way to recognize the project root folder. Maybe, jekyll can provide this info somehow.

{% drawio path="/assets/arch/drawio/Arch_Overview.drawio" page_number=0 height=400 %}

This code means that the plugin will try to open exactly the "/assets/arch/drawio/Arch_Overview.drawio" path disregarding the project root. I'll update the documentation accordingly.

[HoffiMuc]

./docs/dev/arch/Arch_0_Overview.md
./docs/assets/arch/drawio/Arch_Overview.drawio

with relative:

{% drawio path="../../assets/arch/drawio/Arch_Overview.drawio" page_number=0 height=400 %}

but still the same:

/Users/hoffi/.gem/ruby/3.2.2/gems/jekyll-drawio-1.1.1/lib/diagram_extractor.rb:6:in `initialize':
    No such file or directory @ rb_sysopen - ../../assets/arch/drawio/Arch_Overview.drawio (Errno::ENOENT)
	from /Users/hoffi/.gem/ruby/3.2.2/gems/jekyll-drawio-1.1.1/lib/diagram_extractor.rb:6:in `open'
	from /Users/hoffi/.gem/ruby/3.2.2/gems/jekyll-drawio-1.1.1/lib/diagram_extractor.rb:6:in `extract_diagram'
	from /Users/hoffi/.gem/ruby/3.2.2/gems/jekyll-drawio-1.1.1/lib/jekyll-drawio.rb:68:in `render'

any ideas @mutcher ?

[HoffiMuc]

ah, found it out:

{% drawio path="assets/arch/drawio/Arch_Overview.drawio" page_number=0 height=400 %}

without a leading / in path before assets works ...

I apologize for the inconveniences.

[HoffiMuc]

unfortunately it doesn't work with github pages :(

(but I fear that's (currently) beyond what you want to achieve)

@mutcher or can you "guide" me on how to include a copy of jekyll-drawio in docs/_plugins ??

Gemfile

gem "github-pages", group: :jekyll_plugins

group :jekyll_plugins do
  gem "jekyll-feed", "~> 0.12"
  gem "jekyll-drawio", "~> 1.1.1"
end

github workflow error:

ADDENDUM: tried out many things, but couldn't get it to work with github actions workflow for github-pages

But if you consider implementing something for it, I am happy to assist!

[HoffiMuc]

but one last question: (as I am a total jekyll noob)

is it possible to have jekyll-drawio gem in _plugins so that I don't need the gem and github pages doesn't complain on your drawio tags???

Own answer: yes it is ... but doesn't help as github-pages run in safe mode, so won't work either
