Extra space in array definition breaks following indentation scopes.

[enyo]

This coffee script:

describe "test", () ->
  x = [
    1, 2
   ] # <-- A space at the beginning of this line
  describe "innerTest", () ->
    "Wrong indentation"

(note the extra space before ])

compiles to:

describe("test", function() {
  var x;
  return x = [1, 2];
});

describe("innerTest", function() {
  return "Wrong indentation";
});

This only happens with exactly one space. Two spaces pass just fine, and more result in a syntax error.

Not exactly. It happens with any number greater than zero and less than the number of spaces you're using as indentation. See #1275. Closing as duplicate.

Sorry, I went through all the bug reports but didn't make the connection to this one.

But actually: no, it doesn't happen with 2 spaces. Two spaces and no (EDIT) space result in exactly the same code. (not that it matters...)

I believe you are mistaken. My previous statement is correct. Paste shell sessions if you'd like to supplement your argument.

0/3 extra spaces

$ coffee -bsp
do ->
   a = [
      0
   ]
   b = 1
(function() {
  var a, b;
  a = [0];
  return b = 1;
})();

1/3 extra spaces

$ coffee -bsp
do ->
   a = [
      0
    ]
   b = 1
var b;

(function() {
  var a;
  return a = [0];
})();

b = 1;

2/3 extra spaces

$ coffee -bsp
do -> 
   a = [
      0
     ]
   b = 1
var b;

(function() {
  var a;
  return a = [0];
})();

b = 1;

3/3 extra spaces

$ coffee -bsp
do ->
   a = [
      0
      ]
   b = 1
(function() {
  var a, b;
  a = [0];
  return b = 1;
})();
$

With one space:

enyo@matbook:~$ coffee -bsp
describe "test", () ->
  x = [
    1, 2
   ] # <-- One space
  describe "innerTest", () ->
    "Wrong indentation"

# Results in:

describe("test", function() {
  var x;
  return x = [1, 2];
});

describe("innerTest", function() {
  return "Wrong indentation";
});

With two spaces:

enyo@matbook:~$ coffee -bsp
describe "test", () ->
  x = [
    1, 2
    ] # <-- Two spaces
  describe "innerTest", () ->
    "Correct indentation"

# Results in:

describe("test", function() {
  var x;
  x = [1, 2];
  return describe("innerTest", function() {
    return "Correct indentation";
  });
});

So, you agree with me then, correct? Your comment

Two spaces and one space result in exactly the same code

has been shown to be false.

[enyo]

Sorry.. that was a mistake.. Two spaces and no space are exactly identical (I updated my response).

The current block is only terminated in my case, when there is exactly one space. Zero and 2 spaces are the same (result in the normal expected code). 3 Spaces result in a parse error.
