Join multiple Coffeescript files into one file? (Multiple subdirectories)
I've got a bunch of .coffee files that I need to join into one file.
I have folders set up like a rails app:
/src/controller/log_controller.coffee
/src/model/log.coffee
/src/views/logs/new.coffee
Coffeescript has a command that lets you join multiple coffeescripts into one file, but it only seems to work with one directory. For example this works fine:
coffee --output app/controllers.js --join --compile src/controllers/*.coffee
But I need to be able to include a bunch of subdirectories kind of like this non-working command:
coffee --output app/all.js --join --compile src/*/*.coffee
Is there a way to do this? Is there a UNIXy way to pass in a list of all the files in the subdirectories?
I'm using terminal in OSX.
They all have to be joined in one file because otherwise each separate file gets compiled & wrapped with this:
(function() { }).call(this);
Which breaks the scope of some function calls.
You could write a shell script or Rake task to combine them together first, then compile. Something like:
find . -type f -name '*.coffee' -print0 | xargs -0 cat > output.coffee
Then compile output.coffee
Adjust the paths to your needs. Also make sure that the output.coffee file is not in the same path you're searching with find or you will get into an infinite loop.

Additionally you may be interested in these other posts on Stackoverflow concerning searching across directories:
From the CoffeeScript documentation:
-j, --join [FILE] : Before compiling, concatenate all scripts together in the order they were passed, and write them into the specified file. Useful for building large projects.
So, you can achieve your goal at the command line (I use bash) like this:
coffee -cj path/to/compiled/file.js file1 file2 file3 file4
where file1 - fileN are the paths to the coffeescript files you want to compile.
