Question

This is not limited to Rails developers, but I would assume it’s pretty common to have to do this since Rails 3.1.

I’m looking for a script/some method of replacing everything of the form

'../foo/BLAHBLAH'

to <%= asset_path 'BLAHBLAH' %>

where foo is the name of the asset type, so it can be either images or fonts.

Anyone have experience with this?

You can do this with a global search and replace.

In Textmate you can hit Command-Shift-F to enter a project wide search. Then search for \.\.\/images\/(.*?)[\)'"]and replace it with <%= asset_path('$1') %>

With find and sed it’s a simple one liner:

find PROJECT_DIR -type f -name "*.html" -exec sed -i -e 's/\.\.\/images\/\([^)'\''"]*\)/<%= asset_path("\1")/g' {} \;

And in Vim you can do:

:args ./**
:argdo %s/\.\.\/images\/(.*?)[\)'"]/<%= asset_path('\1')/g
