Finding unused partials

There’s a large set of view template changes in my client, part of the soon-to-be-deployed redesign. As I was making some of these changes, I wasn’t very careful to delete partials that aren’t used anymore. So I thought I would whip up some ruby one-liners to find these for me.

The following mix of Ruby and zsh is not the cleanest way to do it, but it gets the job done:

1. List all partials in my client

find . -name “_*.rhtml” | ruby -ane ‘
return unless $_ =~ /\/_(.*).rhtml/
puts $1
‘ > partial_names.txt

2. Count the number of times each is referenced.

for i in `cat partial_names.txt`
echo `grep -r “render.*:partial.*$i” ./shopperview/app/views ./shopperview/app/controllers | wc -l` $i >> partial_frequency.txt

3. Sort partials by the number of times they’re referenced

sort -g partial_frequency.txt
