Retaining line numbers with the Rails asset pipeline

By default the Rails 3 asset pipeline uses the Uglifier gem to optimize and minify your Javascript. One of its many optimisations is to remove all whitespace, turning your Javascript into one very long line of code.

Whist removing all the newlines helps to reduce the file size, it has the disadvantage of making your Javascript harder to debug. If you've tried to track down Javascript errors in minified Javascript files you'll know the lack of whitespace does make life harder.

Luckily there is a simple solution: to configure Uglifier to add newlines back into the code after it performs its optimisations. And if you're serving your files correctly gzip'd, the newlines add only a small increase to the final file size.

You can configure Uglifier to add the newlines by setting the following in your Rails 3 config/production.rb file:

cupakromer

my_array = %w[test one two three]

# Inject takes the value of the block and passes it along
# This often causes un-intended errors
my_array.inject({}) do |transformed, word|
  puts transformed
  transformed[word] = word.capitalize
end
# Output:
# {}

Tmux layouts with tmuxinator

Finally this time, I'm sold on tmux after I used tmuxinator to configure tmux layouts. The default layout didn't work for me, I wanted more control on the split panes. Here's how you can fine tune your tmux layout:

1. Add this to your ~/.tmux.conf -> set -g mouse-resize-pane on
2. Start tmux, split panes, resize panes with mouse to your liking
3. On your shell, run tmux list-windows to list active tmux windows and their layouts
4. Copy paste the layout in tmuxinator project file

# This requires tmux 2.1. a lot of these settings will error on anything earlier.

# Act like Vim; use h,j,k,l to select panes and move the cursor
set-window-option -g mode-keys vi
bind-key h select-pane -L
bind-key j select-pane -D
bind-key k select-pane -U
bind-key l select-pane -R

# Look good
