2. I'm not sure if I understand your correctly, but it should work if you wrap it in (). I actually have that very same example in 'broken.js' [0]
3. Sure. As you can write normal JavaScript, just use:
Car.x = (arg){
//etc
}[0]: https://github.com/binlain/designtojs/blob/master/test/broke...
loadAndPrintFile: (contents) {
if (!contents) {
fs.readFile() -> (error!, contents)
}
console.log(contents);
}
I'm asking because I built something similar (though it only worked with promises, not general async functions), and I'm curious to compare approaches :-) - mine is a sweet.js macro: http://pastie.org/9410315 (uses https://github.com/petkaantonov/bluebird and https://github.com/BranchMetrics/promise-accum). The basic syntax would be:
task {
item1 <- LoadItem(1);
item2 <- LoadItem(item1.foreign_key);
ret <- DoSomethingWithItems(item1, item2);
}(again, beautified because DesignToJS crams everything in one line to preserve the line numbers of your actual code):
function loadAndPrintFile(contents) {
if (!contents) {
fs.readFile(function(error, contents){
if(error !== null && error !== undefined){
return error;
}
});
}
console.log(contents);
}
I'd suggest writing it like this in DesignToJS:
loadAndPrintFile: (contents! console.log) {
fs.readFile() -> (error!, contents! console.log)
}
function loadAndPrintFile(contents) {
if(contents !== null && contents !== undefined){
return console.log(contents);
}
fs.readFile(function(error, contents){
if(error !== null && error !== undefined){
return error;
}
if(contents !== null && contents !== undefined){
return console.log(contents);
}
});
}
