this is the evaluation function for binary expressions (addition only) according to ES2015 spec, expressed in my JS CESK machine.

    eval(fp, store, kont) {
        let lref = this._left.eval(fp, store, kont);
        let lval = es6.GetValue(lref, store);
        let rref = this._right.eval(fp, store, kont);
        let rval = es6.GetValue(rref, store);
        switch (this.operator) {
        case '+': {

Hopefully much of the content of this file will go away and be replaced by something that lives in the actual package file. I'm loathe to create yet another .zip/.jar package, but it might not be the worst thing.

Until then, this file must live in a --module-dir specified on the search path (defaulting to ../lib relative to the compiler executable).

{
    // this version specifies two things: the version of the syntax of this file,
    // as well as the runtime abi in use.  the compiler will (eventually) refuse
    // to load modules which don't match its semver.
    "ejs_version": "0.0.0-alpha1",

GitHub Counter-Notification for CraftBukkit

This counter notification is for:

• https://github.com/Bukkit/CraftBukkit-Bleeding
• https://github.com/Bukkit/CraftBukkit
• and any other repositories covered by https://github.com/github/dmca/blob/master/2014-09-05-CraftBukkit.md

The DMCA takedown request for CraftBukkit was motivated by license terms that do not apply to source code in situ, only to the distribution of resulting binary packages. The multiple claims of problems in the repository have nothing to do with the actual source code, but with resulting binary releases.

Indeed, in the original notice, this line:

#ejs modules (what I want to see)

##the easier bits

take the following modules:

// for template strings without a tag (i.e. of the form
// `literal ${with}${possibly}${substitutions}`) we simply
// inline the spec'ed behavior of the default handler (zipping
// together the cooked values and substitutions to form the
// result.)
//
// for tagged templates: (i.e. of the form tag`literal`) we
// create a function which lazily generates the const/frozen
// callsite_id, which is a unique object containing both raw

I'm working on ejs's support for generator functions, and have a few tests that I think exercise more complex interactions with JS syntax. Control flow interactions are the ones we naturally think about, like nested try/catch/finally (ugh, finally), loops, breaks/continue statements with labels, etc.

Lexical scoping is also one of those complex interactions, one that bugs me more than the others.

Here's one of my current tests:

function* foo() {
  for (var i = 0; i < 10; i ++) {
    let x;
 yield x;
