00:00:00,140 --> 00:00:02,580
Now that we saw some of the git basic
2
00:00:02,580 --> 00:00:05,689
functionalities in practice, let's go a step further. If
3
00:00:05,689 --> 00:00:08,420
you remember I mentioned before that many of these
4
00:00:08,420 --> 00:00:12,250
version control systems are actually integrated into IDE's. So
5
00:00:12,250 --> 00:00:14,540
what were going to look at next is what happens
6
00:00:14,540 --> 00:00:17,500
if we put together git and eclipse. And the
7
00:00:17,500 --> 00:00:20,960
result is egit, or EGit is a plug in
8
00:00:20,960 --> 00:00:25,520
for the eclipse IDE that adds git functionality to eclipse.
9
00:00:25,520 --> 00:00:27,880
So let's see how that works in practice. So
10
00:00:27,880 --> 00:00:31,400
support for git is available in many IDE's including
11
00:00:31,400 --> 00:00:33,920
Eclipse. And if you want to get github
12
00:00:33,920 --> 00:00:38,620
for Eclipse, you should go to eclipse.github.com and you can
13
00:00:38,620 --> 00:00:41,445
download the plugin. So this bring us to the
14
00:00:41,445 --> 00:00:44,530
plugin page and you can use the provided URL
15
00:00:44,530 --> 00:00:47,060
and directions to install the plugin. In this case
16
00:00:47,060 --> 00:00:49,945
we're going to copy this address. So we're going to
17
00:00:49,945 --> 00:00:54,110
Eclipse, Help, Install new software. We can click on Add
18
00:00:54,110 --> 00:00:56,810
to add a new site from which to get software. We
19
00:00:56,810 --> 00:00:59,110
paste the location that we just copied here. And we
20
00:00:59,110 --> 00:01:02,842
can give it a descriptive name. In this case I'll just
21
00:01:02,842 --> 00:01:06,645
call it Eclipse Git plugin. Then when I click okay,
22
00:01:06,645 --> 00:01:09,720
Eclipse will go, and look for plugins. And as you can
23
00:01:09,720 --> 00:01:12,510
see, there are two options. We can select both of them,
24
00:01:12,510 --> 00:01:15,180
and click on next. You can see that the Eclipse identified
25
00:01:15,180 --> 00:01:18,330
a few dependencies. You can click next and accept them. You can
26
00:01:18,330 --> 00:01:21,540
accept the terms and conditions for the plug in, and then just
27
00:01:21,540 --> 00:01:25,730
finish. And at this point, Eclipse will install the plugin, which might
28
00:01:25,730 --> 00:01:28,610
take a little bit of time. So we're just going to speed it up.
29
00:01:28,610 --> 00:01:31,110
And when Eclipse is done, you will get this prompt that will
30
00:01:31,110 --> 00:01:33,670
tell you that you need to restart Eclipse for the plugin to
31
00:01:33,670 --> 00:01:36,990
be actually installed. And at this point, you want to click yes. And
32
00:01:36,990 --> 00:01:40,550
when Eclipse restarts. You'll have your plugin. We're going to go to the git
33
00:01:40,550 --> 00:01:44,030
repository perspective that we can select here. And when we click
34
00:01:44,030 --> 00:01:47,160
OK, you can see that our display will change. And since
35
00:01:47,160 --> 00:01:49,360
we don't have any repository yet, we are provided with the
36
00:01:49,360 --> 00:01:53,620
possibility of adding an existing local git repository, cloning a git repository
37
00:01:53,620 --> 00:01:56,330
or creating a new local git repository. We're going to add an
38
00:01:56,330 --> 00:01:59,800
existing local repository. This is the one that we created earlier,
39
00:01:59,800 --> 00:02:02,170
so we'll select it and click finish, and you can see
40
00:02:02,170 --> 00:02:05,660
that my project is now added to this set of git repositories.
41
00:02:05,660 --> 00:02:09,240
Now let's check out the project from the repository by selecting import
42
00:02:09,240 --> 00:02:12,530
project. And here you can import something as an existing project, you
43
00:02:12,530 --> 00:02:15,300
can use a new project wizard, and in this case I chose
44
00:02:15,300 --> 00:02:18,680
the option of importing as a general project. Then I click Next and
45
00:02:18,680 --> 00:02:20,870
as you can see, I have the project name up there and
46
00:02:20,870 --> 00:02:24,630
I can click Finish. So now, if I go to the resource perspective
47
00:02:24,630 --> 00:02:27,740
by clicking here, I can see that the project has been added
48
00:02:27,740 --> 00:02:30,760
to my set of projects. And I can see all the files within
49
00:02:30,760 --> 00:02:33,440
the project, particularly, if I click on the README, you can see
50
00:02:33,440 --> 00:02:36,190
that we have the Readme file that we created before. Same thing for
51
00:02:36,190 --> 00:02:38,930
the test file. One thing I can do at this point, it
52
00:02:38,930 --> 00:02:41,070
to execute different git commands, perform
53
00:02:41,070 --> 00:02:43,430
different git operations by using the team
54
00:02:43,430 --> 00:02:47,010
submenu in the contactual menu. And here there are several things
55
00:02:47,010 --> 00:02:50,650
I can do including some advanced commands. And just to give it a
56
00:02:50,650 --> 00:02:53,200
shot, I am going to try to click show local history, and this
57
00:02:53,200 --> 00:02:56,180
shows the history of the file. For example it shows the author and
58
00:02:56,180 --> 00:02:59,200
it shows when he was created, when he was authored. Lets make
59
00:02:59,200 --> 00:03:02,810
some changes to this file by adding some new content. Okay. I saved
60
00:03:02,810 --> 00:03:05,160
the file and now I can see that error that indicates that my
61
00:03:05,160 --> 00:03:08,620
file was locally changed. So now if I go to the team menu,
62
00:03:08,620 --> 00:03:11,380
you can see that I have the option to add to the index,
63
00:03:11,380 --> 00:03:14,686
to stage the file. And now I got this new label that star
64
00:03:14,686 --> 00:03:17,980
that shows the files added to the index. And now at this point,
65
00:03:17,980 --> 00:03:21,270
I can go to the team menu again and I can actually commit
66
00:03:21,270 --> 00:03:25,480
the file by selecting the corresponding entry. This allows me to enter
67
00:03:25,480 --> 00:03:28,390
the commit message, exactly in the same way which I could do
68
00:03:28,390 --> 00:03:31,250
that from the command line with the textual editor. And after I
69
00:03:31,250 --> 00:03:34,050
put the comment there, I can actually commit. And now if we
70
00:03:34,050 --> 00:03:36,320
look at the history view, we can see here that we have
71
00:03:36,320 --> 00:03:38,960
a new version for the file that we just modified. And we
72
00:03:38,960 --> 00:03:42,250
can also see the commit comment. And, at this point, if we
73
00:03:42,250 --> 00:03:46,450
had remote repository we could push our changes to that remote repository
74
00:03:46,450 --> 00:03:49,330
as well. Again, using the team submenu and
75
00:03:49,330 --> 00:03:52,170
the contextual menu. And, speaking of remote repositories, what we
76
00:03:52,170 --> 00:03:55,230
are going to see next is how to use GitHub
77
00:03:55,230 --> 00:03:58,640
repositories which are remote repositories that are hosted on GitHub.
