Nanoc is a web publishing system written in Ruby.

and just launch $ bundle exec nanoc view

now I need to do $ bundle exec nanoc view -o 0.0.0.0

Gregory Pakosz

@gpakosz

in that respect I wish cri was able to read options from environment variables

I think nanoc view defaults to binding to localhost only

(which makes sense from a security point of view)

Gregory Pakosz

@gpakosz

which doesn't make sense for a dev tool

I mean who serves a site with nanoc view?

Gregory Pakosz

@gpakosz

does nanoc view still require adsf?

and what to do when trying to connect live reload yields Cannot download livereload.js

@gpakosz

hmm seems to be caused by

I'm using bundle exec nanoc live -L -V

apparently I can't use nanoc live -L if I have guard live reload

it's both logical and so confusing

Gregory Pakosz

@gpakosz

Also @ddfreyne , a bigger timeout doesn't always help
I'm still hitting

Magick::ImageMagickError: unable to open image `/vagrant/output/images/convert-batch.png': No such file or directory @ error/blob.c/OpenBlob/2874

Current item: /tools/inktool/overview.md (:default representation)

  0. _factory/lib/images.rb:43:in `ping'
  1. _factory/lib/images.rb:43:in `image'
  2. item /tools/inktool/overview.md (rep default):185:in `get_binding'

Item A depends on Image B. And Item A's compilation tries to open image in output/ before it has arrived

I'm not sure if you commented that already but imho when an item A depends on a binary item B, the only correct option is to wait for item B to arrive in output/ before launching compilation of item A. Is it what Nanoc is currently doing?

damn and guard doesn't work with Vagrant :(

Gregory Pakosz

@gpakosz

is there a way I can ask nanoc live to launch guard -p to force polling ?

Denis Defreyne

@ddfreyne

@gpakosz I think in that case, I’d run nanoc live and guard separately

nanoc live (the one that is provided by guard-nanoc) is a thin wrapper around both

Gregory Pakosz

@gpakosz

you meant nanoc view and guard?

Denis Defreyne

@ddfreyne

Yep, sorry

@a4z

what it the 'trick' in the blogging extension, why the question if items are frozen, and if, the data gets assigned to a variable just to return that

      blk = -> { @items.select { |item| item[:kind] == 'article' } }
      if @items.frozen?
        @article_items ||= blk.call
      else
        blk.call
      end

I can understsand that there might be some caching wanted, and that the result is returned if it exists
or does this something different?
but why the items.frozen question ? if this is not the case there is no caching, when is which branch relevant?

Harald

@a4z

my second question for this evening is, is there a way to influence that certain item will pe written out after others ?

Denis Defreyne

@ddfreyne

@a4z Yep, that is related to caching. The list of items is becomes frozen after preprocessing

Are the people having performance issues with the host file system in Docker running on Macs? The main issue is not file system speed per se but the overhead required to get bidirectional consistency. There are mount options that can improve performance a fair bit depending on what you're doing. See https://docs.docker.com/docker-for-mac/osxfs-caching/ for details.

Ran into this on a project I was working on recently: https://github.com/iay/shibboleth-build-docker/blob/master/README.md#performance

(The workround we used -- temporarily moving the data to /tmp in the container -- obviously wouldn't apply here)

Denis Defreyne

@ddfreyne

@iay So far I’ve avoided using Docker on Mac because of speed issues…

Harald

@a4z

is there a way to call compile from the post processign step?

Gregory Pakosz

@gpakosz

no because it's a post processing step, compilation and routing have happened by then

Harald

@a4z

hm, that what I have expected, but it is sad, have now all pieces together, and I am super happy, but I have that one use case where I would need to influence that one page is processed after others, and I do not know how to do that

@gpakosz

@ddfreyne hello, do you think you can make a point release with the longer timeout soon?

Harald

@a4z

So, if you have one blog index page that depends on all individual articles, you could do e.g. @items.find_all('/articles/*').each(&:path) to force a dependency onto all those pages

A question to this ... what does it mean.. :-) , what does .each(&:path) actually call on the item?
my ruby is not that strong, and from the doc I see there is a path property, but I am unsure how that relates, but I am very interested in understanding .

Denis Defreyne

@ddfreyne

.each(&:path) is the same as .each { |something| something.path } — it’s syntactic sugar

So essentially, it loops over the collection and calls the path method on it

(and the call to #path makes Nanoc record a dependency onto the item that you called the #path methd on)

Harald

@a4z

Thanks for the explanation! so I call the path method on all blog articles, but when do I do that and how does this relate the the blogindex page?

Do I need to have a own rule for the blogindex page and do this in this rule?

Harald

@a4z

oh, I think I found it , I do it in the blog index erb page ? and this creates a dependency just because I call a method on the item? magic, this is magic !
(have of course to try out if this is true but I think it is... tested, seems to be the case, .. magic! )

@a4z

For the atom feed, what do I need to do that not the whole content of a page/article lands in the feed.xml for each entry, but only the excerpt ?

Hello @ddfreyne. I'm interested in helping to solve my recently raised issue nanoc/nanoc#1502 if I can. The only problem is that I'm not quite sure yet of a suitable approach - I'd welcome any pointers if/when you have the time! :slight_smile:

Denis Defreyne

@ddfreyne

@ethancrawford Hi! I think the way to fix it would be to look at utf8.rb (which defines Nanoc::CLI::StreamCleaners::UTF8, check whether str is a UTF-8 string, and if not, return str without doing anything on it

Btw, is there much left to do before merging in the branch where you have extracted the sass filter into its own gem? (I'm still curious about replacing sass with sassc :smile:)

@ethancrawford

..and another question :joy: :sweat_smile: if I were interested in allowing the kramdown filter to parse github flavoured markdown, would you prefer this to be added as a separate filter, or allowed as a config setting to the existing one? :slight_smile:

@a4z

a qeustion to the documentation, the example in the blogger helper for generating a feed is

compile '/blog/feed/' do
  filter :erb
  write '/blog.xml'
end

what input does this actually take? I mean, /blog/feed/ is a folder , so which file will be compiled ?
