This gem attempts to convert RABL templates into the more widely used JBuilder.
$ gem install rabl_to_jbuilder
rabl_to_jbuilder app/views/api/
or
rabl_to_jbuilder app/views/api/orders/show.rabl
RABL has more implicitness than JBuilder, so some behaviour can't be inferred. rabl_to_jbuilder will serve as a good first pass but will usually require some manual editing.
Partials
RABL allows using any template as a partial. JBuilder expects partials to start with an _ (like all Rails partials).
rabl_to_jbuilder doesn't figure out which templates should be partials and assumed everything is a top-level view. Manual renaming is required for now.
Undefined/Missing data
Rabl will ignore any nil data.
It also treats any method missing as nil, basically everything has an implicit .try.
rabl_to_jbuilder makes no attempt to replicate this. You'll have to add ifs or similar around any sections of the template you expect to receive nil.
Object name
RABL has an implicit object. rabl_to_jbuilder guesses at a name using the name of the directory the RABL template is in. Similarly, the object name is guessed when rendering a partial.
After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
