An attempt at writing certified stuff related to LambdaJS (LambdaJS interpreter and JS => LambdaJS compiler)

## Compiling

./get_deps.sh # Slow, you have to compile jscert (and thus Flocq and TLC)
cd LambdaS5
make

The simplest example:

./build/run.byte file.ljs

You can also use stdin:

echo "(func (foo, bar) { bar })('first', 'second')" | ./build/eval.native stdin

You can execute multiple files. The last one has to be a LambdaJS code file, and all the previous ones have to be LambdaJS environment files. For instance:

./build/eval.native ~/js/LambdaS5/envs/es5.env file.ljs

The previous command can be very long (two minutes on my machine), because it has to evaluate the env file, which is rather big.

A faster way, if you have to run multiple files, is to evaluate it once, and dump it. Thus, you only have to load the dump on each run:

./build/eval.native ~/js/LambdaS5/envs/es5.env -save /tmp/store.dump
./build/eval.native -load /tmp/store.dump foo.ljs
./build/eval.native -load /tmp/store.dump bar.ljs

This dump uses Caml's Marshal module, with the Closure flag (because we want to dump TLC's LibStream's streams), so you should load the dump with the exact same version of eval.native as the one used to save it. (You would get a Marshal error otherwise.)

Interpreter written mainly in Coq, in LambdaS5/coq/*.v

“Glue” files written in Caml, in LambdaS5/caml/*.ml. Also uses a modified version of the original LambdaJS lexer and parser, in LambdaS5/caml/ljs/.
