Here is the blog post explaining the next phase of Roots: https://medium.com/@jescalan/eaa10c75eb22#.uacjziaej
Here is the stack they're experimenting with:
- jade - for markup - babel - for JS and JS transforms - postcss - for CSS transforms - webpack - as the core compiler
As this is a work in process, it just means the future of Roots continues to look great.
Pro Custom compilers
Not only does roots support a huge number of languages and compilers out of the box, it also allows you to insert custom compilers if you want. Fun fact, roots is the only static site generator that supports dogescript
Pro Multipass compiles
Roots compiles files once for each extension, which allows for some advanced options if you get to that stage
Pro Client-side templates
Roots will precompile your templates into js, which makes it really smooth to work with client-side MV* frameworks.
Since roots is written in node, everything is compiled in parallel rather than in series, making it very quick.
Con Too much magic happens
For new users it is hard to understand what is going on and why.
Con A little more complicated than other static site generators
Middleman is a big piece of software, it's not simply a static blog generator. Because of all the functionality and flexibility it offers it can be a little more complex than other static site generators and a little harder to learn all of its bells and whistles.
Con No i18n (Internationalization)
There is no i18n support out of the box. And there is only one extension that does i18n compilation with a limited feature set.
