1
00:00:00,340 --> 00:00:03,900
There's one last thing we should cover
before we move onto the next stage, and

2
00:00:03,900 --> 00:00:05,920
that's the Go-Format Tool.

3
00:00:05,920 --> 00:00:08,740
Here we have a file whose
formatting isn't ideal.

4
00:00:08,740 --> 00:00:13,740
Things aren't indented correctly, there's
odd spacing in the function calls and

5
00:00:13,740 --> 00:00:15,070
things like that.

6
00:00:15,070 --> 00:00:18,140
Let's try running the Go-Format
tool on this file.

7
00:00:18,140 --> 00:00:19,910
So, I'm gonna go down here to the console.

8
00:00:19,910 --> 00:00:25,750
I'll type go, I'll run the format
sub-command which is just fmt for short.

9
00:00:26,940 --> 00:00:29,740
And I'll specify the name of
the file that I want it to update.

10
00:00:29,740 --> 00:00:31,616
So that's temp.go.

11
00:00:31,616 --> 00:00:35,300
Run that and it'll print out the name
of the file that it updated.

12
00:00:35,300 --> 00:00:38,690
Then if I switch back up here
to the editor, it will reload.

13
00:00:38,690 --> 00:00:41,640
And you can see that even though
the code looks much the same,

14
00:00:41,640 --> 00:00:43,710
it's been substantially reformatted.

15
00:00:43,710 --> 00:00:45,880
Our import statement's been cleaned up.

16
00:00:45,880 --> 00:00:48,470
The indentation on
everything has been fixed.

17
00:00:48,470 --> 00:00:51,050
The comments are all
aligned with each other and

18
00:00:51,050 --> 00:00:54,320
even the spacing inside
each line has been fixed.

19
00:00:54,320 --> 00:00:57,490
This was done for
us automatically by the Go Format tool.

20
00:00:57,490 --> 00:00:59,990
It analyzed the structure
of our source code and

21
00:00:59,990 --> 00:01:04,880
then indented everything appropriately for
us, and it makes other fixes as well.

22
00:01:04,880 --> 00:01:08,310
Most people don't like all the formatting
changes that Go Format makes.

23
00:01:08,310 --> 00:01:11,340
But the point is that you don't
have to argue about those changes.

24
00:01:11,340 --> 00:01:14,110
Go Format is the standard for
formatting Go code.

25
00:01:14,110 --> 00:01:17,930
The standard format is easier
to read once you're used to it.

26
00:01:17,930 --> 00:01:21,180
And you don't have to manually
make changes anymore to match some

27
00:01:21,180 --> 00:01:22,830
arbitrary style guide.

28
00:01:22,830 --> 00:01:27,270
You should run Go Format on all your Go
code, especially if you're sharing it.

29
00:01:27,270 --> 00:01:31,830
And it's easy to do, sublime text, then
and all the other major text editors can

30
00:01:31,830 --> 00:01:36,130
be set up to automatically run Go Format
on files each time you save them.

31
00:01:36,130 --> 00:01:39,660
So get in the habit, Go Format can
save you a lot of time and trouble
