I want to convert
console.log({
a: 'a'
}, {
b: 'b'
});
into CoffeeScript. The only way I found is
console.log
a: 'a',
b: 'b'
It seems bizarre that a: 'a' and b: 'b' are not indented the same when they are essentially symetric in this situation.
Put the comma one in a separated line, one indentation level less than the hash/object, so it's treated as part of the function invocation.
console.log
a: 'a'
, # indentation level matters!
b: 'b'
this will not work because the indentation level is the same as hash, so it's treated as part of the hash.
console.log
a: 'a'
,
b: 'b'
Or you could use braces, which do work in CS:
console.log {a:'a'}, {b:'b'}
Well, if you think about the parsing rules,
a: 'a',
b: 'b'
actually means
{ a: 'a', b: 'b' }
Since this isn't the behaviour you want, you need to tell the parser that the line with b: is another object. Indenting will do that for you. Now this wasn't really a question, but I hope it helps you understand why to do it the way you described. It is the right way.
$ coffee -bce 'console.log(a: "a"; b: "b")'
// Generated by CoffeeScript 1.2.1-pre
console.log({
a: "a"
}, {
b: "b"
});
