Install Slim as a gem
gem install slim
Create a shell script in your app/views folder
slim2erb.sh
for file in $(find . -name \*.slim); do
erb_file="${file%.*}.erb"
slimrb -c --rails --erb $file | sed 's/::Temple::Utils\.escape_html((\(.*\))) %>/\1 %>/g' > $erb_file
echo $erb_file
done
find . -name "*.slim" -type f -delete
sh slim2erb.sh
Unfortunately, you will need to do some manual work – slimrb doesn’t generate properly formatted ERB templates.
