Why did you choose Lua as the implementation language?

  - Dynamic typing for fast prototyping. The compiler is full of dynamic tricks for testing, stripping parts of it, etc. - LPeg support [1]. PEGs are great! - The creator of Lua was my advisor since undergrad. :) (Which means that I program in Lua for a long time...) http://www.inf.puc-rio.br/~roberto/lpeg/lpeg.html http://www.inf.puc-rio.br/~roberto/lpeg/lpeg.html

    And this means that the performance is not the first (or second) reason to use Ceu, right? In other words, is it somewhat slow?

      I wrote in Lua the source-to-source compiler that takes a ".ceu" and generates a ".c" (the code is a single-threaded state machine), which is then compiled with gcc. The compiler is slow, but not the final binary. We wrote a paper [1] that compares flash,RAM,CPU usage from Céu vs hand-written event-driven code in C. The differences are negligible.

        Why not plug into LLVM? Just generate an LLVM backend.

          - Céu can embed blocks in C and call it directly - C is more portable - C is easier to generate
