Template Converters ERB to SLIM

Currently there are two ways to convert your ERB templates to Slim. One is using the still experimental html2slim gem. The other one is converting to HAML and then to Slim, using the html2haml and haml2slim gems.
Install the gem.
gem install html2slim
Now you have two command line utilities html2slim and erb2slim. Just run erb2slim -h and you'll receive more instructions. The current version (0.0.2) will output something like that:
$ erb2slim -h
Usage: erb2slim INPUT_FILENAME_OR_DIRECTORY [OUTPUT_FILENAME_OR_DIRECTORY] [options]
--trace Show a full traceback on error
-d, --delete Delete ERB files
-h, --help Show this message
-v, --version Print version
Here you can see before and after. Slimmer, hum?

Install HAML dependencies on your environment or your gemset
gem install haml # https://github.com/haml/haml
gem install hpricot
gem install ruby_parser
gem install html2haml
Switch to HAML templating
find . -name '*erb' | \
xargs ruby -e 'ARGV.each { |i| puts "html2haml -r #{i} #{i.sub(/erb$/,"haml")}"}' | \
bash
Install SLIM tool dependency
gem install haml2slim # https://github.com/fredwu/haml2slim
Switch to SLIM templating
find . -name '*haml' | \
xargs ruby -e 'ARGV.each { |i| puts "haml2slim #{i} #{i.sub(/haml$/,"slim")}"}' | \
bash
Clean ERB and HAML templates
find . -type f | egrep "(.erb|.haml)\$" | xargs rm
Remove dependencies
gem uninstall haml
gem uninstall hpricot
gem uninstall ruby_parser
gem uninstall html2haml
gem uninstall haml2slim
That is all, have fun
