images folder missing when creating pdf file

[bremenpl]

Hello there,
I have cloned the repo and tried to generate a pdf version of the book by using:
asciidoctor-pdf progit.asc
I received a lot of error messages informing that all of the *.png images could not be found in directory images:
image to embed not found or not readable
It was because directory images does not exist. I had to create one and copy all *.png files I could find in the repo:
lukasz@debkde:~/progit2$ pwd | find -name "*.png" -type f -exec cp {} ./images \;
After that I could run asciidoctor-pdf progit.asc to generate the book. I really appreciate it, thanks.

You're right.
The images directory does not exist because it is ignored:

$ cat .gitignore
output
.DS_Store

# build artifacts
Gemfile.lock
progit.html
progit.pdf
progit.pdfmarks
progit.epub
progit-kf8.epub
progit.mobi
/images/

Building the book properly is made by calling bundle exec rake which calls Rakefile which create the folder and copies the images contained in book/ into the images folder:

  desc 'prepare build'
  task :prebuild do
    Dir.mkdir 'images' unless Dir.exists? 'images'
    Dir.glob("book/*/images/*").each do |image|
      FileUtils.copy(image, "images/" + File.basename(image))
    end
  end

So the good command to get only the required images into the images folder is:

$ # create and fill the images folder (do it only once)
$ mkdir images
$ cp book/*/images/* images/
$ # generate the PDF
$ asciidoctor-pdf progit.asc

I'll update README.asc with those instructions.
