How to let mocha work with tamejs?

I want to use tamejs to write mocha tests, but mocha doesn't support it by default.

Is there any way to let mocha work with tamejs? I don't want to write .tjs files and compiling them into .js each time before running tests.

How to let tamejs automatically compile all .tjs files into .js?

I'm interested in tamejs, and want to use it in my project.

But I don't want to manually compile them into js files before running/testing, etc. I want to let tamejs monitor a directory, and automatically compiles .tjs to .js when the files change.

Is there any way to do this?

Tamejs can't work with mocha?

See my test code using mocha + tamejs:

test/t.tjs

require('should');

function inc(n, callback) {
  setTimeout(function() {
    console.log('### inc: ' + n);
    callback(n+1);
  }, 1000);
};

describe('test', function(){
  it('show ok with tamejs', function(){
     console.log('### testing ...');
     var result;
     await { inc(1, defer(result)); }
     console.log('result: ' + result);
     result.should.equal(123456); // won't pass
  });
});

Compile it to t.js:

tamejs -o test/t.js test/t.tjs

Run mocha

mocha

Result:

### testing ...
.

✔ 1 test complete (1ms)    

It seems the inc method has never been invoked.

How to simplify the error handling in tamejs?

I'm pretty happy with tamejs, it makes my javascript code much clearer. But I still feel the error handling is a little boring.

See the code:

// callback should be callback(err, nextInt)
function inc(n, callback) {
   setTimeout(function() {
      callback(null, n+1);
   }, 100);
}

await { inc(3, defer(var err, next));}
if(err) throw new Error(err);          // !!! error handling

await { inc(8, defer(var err, next));}
if(err) throw new Error(err);          // !!! error handling

await { inc(12, defer(var err, next));}
if(err) throw new Error(err);          // !!! error handling

await { inc(39, defer(var err, next));}
if(err) throw new Error(err);          // !!! error handling

Since nearly every asynchronous api has callbacks which have a error as the first parameter, we need to get it and check it first.

You can see there are a lot of error handling lines in the sample, which is boring.

Is there any way to simplify it?
