Get rid of that SLIM nonesense from a Rails application.
This script is not perfect nor is it well-tested. I wrote it in times of need without any ambition for it to be production-ready.
If you're stuck with .html.slim files, AND if you want to go back to good-old-erb, AND if you didn't find any better tool, AND if you absolutely understand what this script does (read it!) AND if have a version control to back you up in case anything goes wrong, THEN you can consider using this script.
Use it at your own risk.
Usage: slim2erb [options]
-h, --help : Displays this message
--remove-slim-files : Deletes .html.slim files after transpiling them to ERB.
This script recursively replaces all .html.slim files under your current directory by .html.erb files

I'm using the slim gem to transpile slim into erb. I don't use the --pretty option of slimrb because it produced erb outputs with a bunch of <%= ::Temple::Utils.escape_html(...) %> in them. To overcome this issue, I give the disable_escape=true option to slimrb, then I call htmlbeautifier to have a nicer output. It's not perfect (there are some newlines I don't know how to get rid of yet) but it's much better than the SLIM burden I had so far.
I strongly advice you make sure the transpiled code does not create any security issues in your app. For instance, make sure there are no unsafe string displayed without appropriate treatment (html_escape for instance).
