EEx2Slime

Script for converting EEx templates to Slime. Slime is a lightweight template language.

Usage

You may convert files using the included executable eex2slime:

$ gem install eex2slime

$ eex2slime foo.html.eex                   # outputs to foo.html.slime by default
$ eex2slime foo.html.eex bar.html.slime    # outputs to bar.html.slime
$ eex2slime foo.html.eex -                 # outputs to stdout
$ cat foo.eex | eex2slime                  # input from stdin, outputs to stdout
$ eex2slime dir/                           # convert all .eex files recursively
$ eex2slime --delete dir/                  # delete .eex files after convertion. Be sure you have a backup!

Alternatively you could use the following API:

require 'eex2slime'
EEx2Slime.convert('path/to/file')
EEx2Slime.convert_string('<nav class="navbar"></nav>')

Installation

gem install eex2slime

Does it really work?

It might fail in some cases, but in general yes, it does! I've checked it on the opersourced changelog.com app. After a bit of preparing this tool finely converted all EEx templates.

CI runs tests on Rubies 2.2, 1.9.3. Ruby 1.8.7 isn't supported.

Known issues

• Incorrect HTML will break inner HTML parser. Example (notice misplaced slash):

  <img width="75" / height="75">
  

• Nested interpolation won't play well with Slime. This:

  <img src="<%= static_url(@conn, "/images/podcasts/#{@podcast.slug}.svg") %>">
  

  should be rewritten to:

  <% image_url = static_url(@conn, "/images/podcasts/#{@podcast.slug}.svg") %>
  <img src="<%= image_url %>">
  

• This library doesn't support inline if's interpolation:

  <!-- such constructions aren't supported -->
  <article class="<%= if index == 0 do %>is-active<% end %>"></article>
  

• With EEx you could do something like this:

  # header.html.eex
  <div class="container">
  
  # body.html.eex
  body content is expected to be inside container div
  
  # footer.html.eex
  </div>
  

  Slime doesn't support this, so eex2slime will produce non-expected output (body won't be nested inside the container). Be wary.
