0 not taken in account
on https://blocklycodelabs.dev/codelabs/custom-generator/index.html?index=..%2F..index#6
The array block generator example does not take in account the value 0 for integers.
The example code is:
const values = [];
for (var i = 0; i < block.itemCount_; i++) {
let valueCode = codelabGenerator.valueToCode(block, 'ADD' + i,
codelabGenerator.PRECEDENCE);
if (valueCode) {
values.push(valueCode);
}
}
and mentions that null values are not taken in account but 0 return false on the if and is not taken in account too.
I replaced it with
values.push([undefined, null, ""].indexOf(valueCode) > -1 ? 'null' : valueCode);
But still not working to 0. I debugged a bit the code and the file generator.js on line 259 has the next code
if (!code) {
return '';
}
I think here appear the same issue, but this is inside the library code, do you have any workaround to create my custom code generator fixing it, or am I doing / understanding something wrong?
