Set Up Octopress in Arch Linux

Disclaimer: Hack and slash

Well I started using an ancient arch install I had - and I needed to use my blog. Given I know nothing of ruby and octopress had left me with open questions I doubted I’d succed. Well I did - here is how:

[root@mrsd-arch utumno]# pacman -S ruby
Packages (2) libyaml-0.1.6-1  ruby-2.2.3-1
##: hmmm - warning below I missed, see below
The default location of gem installs is $HOME/.gem/ruby
Add the following line to your PATH if you plan to install using gem
$(ruby -rubygems -e "puts Gem.user_dir")/bin
##: ....

Then:

[root@mrsd-arch utumno]# gem install bundler
Fetching: bundler-1.10.6.gem (100%)
##: hmmm - warning below I missed, see below
WARNING:  You don't have /root/.gem/ruby/2.2.0/bin in your PATH,
      gem executables will not run.
Successfully installed bundler-1.10.6
##: ....
[root@mrsd-arch utumno]# exit

I did not want to install octopress - just keep using my existing blog:

utumno@mrsd-arch ~ $ cd /mnt/win/Dropbox/Udun/octopress/
utumno@mrsd-arch /mnt/win/Dropbox/Udun/octopress (source) $ rake preview
rake aborted!
LoadError: cannot load such file -- bundler/setup
/mnt/win/Dropbox/Udun/octopress/Rakefile:2:in `<top (required)>'
(See full trace by running task with --trace)

Remember the warnings ? Issue:

PATH="$(ruby -e 'print Gem.user_dir')/bin:$PATH"

Then - below from a fresh install:

utumno@mrsd-arch /mnt/win/Dropbox/Udun/arch_octopress/octopress (master) $ bundle install

SystemExit: exit
An error occurred while installing RedCloth (4.2.9), and Bundler cannot
continue.
Make sure that `gem install RedCloth -v '4.2.9'` succeeds before bundling.

Ooops - back to my own blog:

utumno@mrsd-arch /mnt/win/Dropbox/Udun/arch_octopress/octopress (master) $ cd ../../octopress/
utumno@mrsd-arch /mnt/win/Dropbox/Udun/octopress (source) $ rake preview
You have requested:
  RedCloth ~> 4.2.9

The bundle currently has RedCloth locked at 4.2.9.
Try running `bundle update RedCloth`
Run `bundle install` to install missing gems.

No clue what all this means:

utumno@mrsd-arch /mnt/win/Dropbox/Udun/octopress (source) $ bundle update RedCloth

Hmm - let’s see:

Gem::LoadError: You have already activated rake 10.4.2, but your Gemfile requires rake 10.3.2. Prepending `bundle exec` to your command may solve this.

That’s ruby traceback - help - cross fingers:

Well - clear enough (although I had no idea) - decided to go with nodejs:

looking for conflicting packages...

AAARGHH moment - googling for this did not really help - made me start hacking and slashing in /plugins/octopress_filters.rb. Ruby tracebacks kept shifting and I quited.

Till next day it dawned me - how about updating octopress itself ? NB: I am not sure how to go about this, but I do it by

$ git checkout master # in my blog repository, 'source' branch is checked out
$ git pull # if octopress is set up correctly pulls the latest octopress master
$ git checkout -b source-before-rebase-2016-03-13 source # create a backup branch if rebase below fails
$ git checkout source
$ git rebase master
$ bundle update
$ rake update_source
$ rake update_style

Unfortunately the last part of the update did not run for me (edit: to solve this delete the sass.old by yourself.):

utumno@mrsd-arch /mnt/win/Dropbox/Udun/octopress (source) $ bundle exec rake update_style
removed existing sass.old directory
rm -r sass.old
rake aborted!
ArgumentError: parent directory is world writable, FileUtils#remove_entry_secure does not work; abort: "sass.old" (parent directory mode 40777)
/mnt/win/Dropbox/Udun/octopress/Rakefile:186:in `block in <top (required)>'
Tasks: TOP => update_style
(See full trace by running task with --trace)

Well - no harm I guess (and why being world writable is a problem escapes me) - cause generate worked:

utumno@mrsd-arch /mnt/win/Dropbox/Udun/octopress (source) $ bundle exec rake generate
## Generating Site with Jekyll
    write source/stylesheets/screen.css

      Generating...
     Build Warning: Layout 'nil' requested in blog/categories/octopress......

YEY!

Edit: to solve the traceback above delete the sass.old by yourself.
