Many of my views are SLIM templates and I wish to add a vote_form partial to my app. How would I convert this partial view from ERB to SLIM?
<strong class="result">Votes: <%= voteable.votes_for - voteable.votes_against %></strong> <%= form_tag user_votes_path(current_user) do |f| %> <%= radio_button_tag :thumb_direction, :up %> <%= radio_button_tag :thumb_direction, :down %> <%= hidden_field_tag :voteable, @voteable %> <%= submit_tag :vote %> <% end %> Thanks :)
You can simply use html2slim gem
gem install html2slim This package include a tool called erb2slim which can convert erb file to slim recursively. Option -d for delete the erb file after the convert finished.
erb2slim -d <dir of your views> You must pass through HAML !
Install HAML dependencies on your environment or your gemset
gem install html2haml # This was moved out of haml gem gem install ruby_parser 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 . -name '*erb' -exec rm -f {} \; find . -name '*haml' -exec rm -f {} \; Remove dependencies
gem uninstall html2haml gem uninstall ruby_parser gem uninstall haml2slim That all, have fun
Here you are, just paste the erb code and hit 'go':

This is based on @Joel's brilliant answer. I had to modify it a bit since some gems seem to have moved and I made some other improvements:
gem install ... portion can then be emitted to make for faster processing.Update: The conversion through haml is no longer required. This is the updated script:
#### gem install html2slim # this will install `erb2slim` command line tool. find . -name '*erb' | \ xargs ruby -e 'ARGV.each { |i| puts "erb2slim #{i} #{i.sub(/erb$/,"slim")}"}' | \ bash # Clean ERB templates find . -name '*erb' -exec rm -f {} \; git add app/views/* git commit -m "Replace erb with slim" In my example (after running rails g devise:views)all the .erb files were replaced with .slim files and then deleted:
Sometimes I just wan to convert a snipped. Like it was mentioned before. In such cases I use
https://html2slim.herokuapp.com
So here we go:
# You must pass through HAML ! # Install HAML dependencies on your environment or your gemset gem install haml html2haml hpricot ruby_parser haml2slim # Switch to HAML templating find . -name '*erb' | \ xargs ruby -e 'ARGV.each { |i| puts "html2haml -r #{i} #{i.sub(/erb$/,"haml")}"}' | \ bash #Switch to SLIM templating find . -name '*haml' | \ xargs ruby -e 'ARGV.each { |i| puts "haml2slim #{i} #{i.sub(/haml$/,"slim")}"}' | \ bash # Clean ERB and HAML templates find . -name '*erb' -exec rm -f {} \; find . -name '*haml' -exec rm -f {} \; I like the de facto answer but thought people would love to know about a new gem which does this much faster and with less hassle. It is at the moment however fairly buggy. :(
Check out html2slim. Say I want to change all my views from .erb to .slim, then I run (from scratch, and from your rails root directory) the following:
gem install html2slim erb2slim app/views --delete If you run erb2slim -h you can see that -d/--delete is an option to delete the erbs afterwards and --trace shows a full traceback on any errors. A note from the author that it is still experimental.
Simply rename the file to end with .html.slim instead of .html.erb, and replace the content with something like the following:
strong.result= "Votes: #{voteable.votes_for - voteable.votes_against}" = form_tag user_votes_path(current_user) do = radio_button_tag :thumb_direction, :up = radio_button_tag :thumb_direction, :down = hidden_field_tag :voteable, @voteable = submit_tag :vote This is online tool does exactly what you want http://erb2slim.herokuapp.com is convert erb snippets to slim.
As in previous answers I use two gems:
gem install html2haml haml2slim Then:
find app/views -name \*.erb -print | sed 'p;s/.erb$/.haml/' | xargs -n2 sh -c 'html2haml "$0" "$1" && rm "$0"' to replace *.erb with converted *.haml versions.
Now to convert *.haml to *.slim and remove *.haml files:
haml2slim -d app/views After all optionally:
gem uninstall html2haml haml2slim
