00:00:00,106 --> 00:00:02,606
(intro music)

00:00:05,430 --> 00:00:07,380
Frank: In this video, we'll go over the steps necessary

3
00:00:07,380 --> 00:00:10,890
to create our own custom project template.

4
00:00:10,890 --> 00:00:11,730
The idea here is

5
00:00:11,730 --> 00:00:13,710
that we can create our own project templates.

6
00:00:13,710 --> 00:00:15,300
And when we create our projects,

7
00:00:15,300 --> 00:00:18,030
we can use this template as the starting point.

8
00:00:18,030 --> 00:00:21,750
That way we'll have a proper main.cpp file.

9
00:00:21,750 --> 00:00:23,550
We'll have all our switches set,

10
00:00:23,550 --> 00:00:25,140
we'll have our environment set.

11
00:00:25,140 --> 00:00:26,160
Alright, so let's get started.

12
00:00:26,160 --> 00:00:28,680
First thing you need to do is open up a workspace.

13
00:00:28,680 --> 00:00:31,650
I've got a workspace already open, I already created

14
00:00:31,650 --> 00:00:33,000
I should say I'm gonna open it now.

15
00:00:33,000 --> 00:00:34,530
I'm gonna say open workspace.

16
00:00:34,530 --> 00:00:36,510
If you don't have a workspace at all

17
00:00:36,510 --> 00:00:38,820
you could just say File, New Workspace.

18
00:00:38,820 --> 00:00:40,560
So I'll open the workspace that I've got.

19
00:00:40,560 --> 00:00:43,530
It's on my desktop and it's called CPPWorkspace.

20
00:00:43,530 --> 00:00:44,643
So I'll open that.

21
00:00:46,350 --> 00:00:47,520
And the first thing you wanna do is

22
00:00:47,520 --> 00:00:48,720
you want to add a project.

23
00:00:48,720 --> 00:00:51,360
So you wanna right click on your workspace

24
00:00:51,360 --> 00:00:53,763
and say New, New Project.

25
00:00:55,290 --> 00:00:57,540
Now here you've got the New Project Wizard

26
00:00:57,540 --> 00:00:59,160
and you've got different examples.

27
00:00:59,160 --> 00:01:01,950
You can create GUI applications, console applications,

28
00:01:01,950 --> 00:01:04,290
you can have user templates and so forth.

29
00:01:04,290 --> 00:01:06,330
What we want to do is,

30
00:01:06,330 --> 00:01:10,500
we want to use the simple executable g++ template

31
00:01:10,500 --> 00:01:12,630
that comes with CodeLite.

32
00:01:12,630 --> 00:01:14,040
And we want to tweak that our own way.

33
00:01:14,040 --> 00:01:15,360
And then what we want to do is we want to create

34
00:01:15,360 --> 00:01:18,000
our own template in here that we can choose.

35
00:01:18,000 --> 00:01:19,440
And we could put it in console or

36
00:01:19,440 --> 00:01:20,940
we can put it here in user templates.

37
00:01:20,940 --> 00:01:22,710
We could put it wherever we'd like.

38
00:01:22,710 --> 00:01:25,080
Okay? But before we do that, we need to create a project.

39
00:01:25,080 --> 00:01:25,913
So let's do that.

40
00:01:25,913 --> 00:01:29,100
I'm gonna select console and let's use the g++

41
00:01:29,100 --> 00:01:31,560
simple executable console template.

42
00:01:31,560 --> 00:01:32,583
I'll press next.

43
00:01:34,080 --> 00:01:35,880
The project name, it doesn't really matter.

44
00:01:35,880 --> 00:01:39,120
I'll just say sample since we're gonna save it

45
00:01:39,120 --> 00:01:42,393
as a template anyway, and I'll select next.

46
00:01:43,230 --> 00:01:45,830
We wanna make sure our compiler is set up correctly.

47
00:01:49,500 --> 00:01:52,590
Here I'm using MinGW and the gdb debugger.

48
00:01:52,590 --> 00:01:53,673
I'll select finish.

49
00:01:54,930 --> 00:01:56,970
And that creates our project.

50
00:01:56,970 --> 00:01:58,260
You can see here's the source file

51
00:01:58,260 --> 00:01:59,580
and here's the CPP file,

52
00:01:59,580 --> 00:02:01,770
which is really C code and not c++ code.

53
00:02:01,770 --> 00:02:03,390
But we'll fix all this in a minute.

54
00:02:03,390 --> 00:02:05,070
So, first thing we wanna do is

55
00:02:05,070 --> 00:02:07,830
we wanna get rid of this and let's write

56
00:02:07,830 --> 00:02:09,570
a simple c++ program.

57
00:02:09,570 --> 00:02:11,340
So same one we've been writing all along.

58
00:02:11,340 --> 00:02:12,790
So we'll say include

59
00:02:14,100 --> 00:02:15,510
iostream,

60
00:02:15,510 --> 00:02:17,790
we'll include iostream since we're gonna probably use it

61
00:02:17,790 --> 00:02:19,690
in most of the projects that we write.

62
00:02:20,790 --> 00:02:22,340
Then we have our main function,

63
00:02:24,480 --> 00:02:27,840
and again it's int main open, close parens,

64
00:02:27,840 --> 00:02:28,830
and then an open curly

65
00:02:28,830 --> 00:02:31,323
which will be automatically closed by Codelite.

66
00:02:32,310 --> 00:02:35,130
Here we can indent in by just pressing tab

67
00:02:35,130 --> 00:02:38,763
and we could say std::cout.

68
00:02:40,200 --> 00:02:43,477
And then the insertion operator followed by the string

69
00:02:43,477 --> 00:02:44,487
"Hello world".

70
00:02:45,900 --> 00:02:48,540
And you can type anything you like here for "Hello World".

71
00:02:48,540 --> 00:02:52,500
And we'll do also an std::endl;.

72
00:02:52,500 --> 00:02:53,973
This prints a new line.

73
00:02:55,410 --> 00:02:57,690
That way when we display "Hello World", the cursor will go

74
00:02:57,690 --> 00:02:59,910
to the next line on the console.

75
00:02:59,910 --> 00:03:02,430
And then finally we'll just return zero like we always do.

76
00:03:02,430 --> 00:03:03,570
That's it.

77
00:03:03,570 --> 00:03:05,340
I'm going to save this.

78
00:03:05,340 --> 00:03:06,810
So I'm gonna press control S here.

79
00:03:06,810 --> 00:03:09,390
So I've just done that and saved it.

80
00:03:09,390 --> 00:03:11,400
Now we'll set some compiler settings and we'll do

81
00:03:11,400 --> 00:03:12,900
this the one time and then we'll save it

82
00:03:12,900 --> 00:03:14,580
as a project template.

83
00:03:14,580 --> 00:03:17,820
So let's go to the sample project, the actual project name

84
00:03:17,820 --> 00:03:21,153
and we'll right click go down to Settings,

85
00:03:22,770 --> 00:03:24,390
Global Settings.

86
00:03:24,390 --> 00:03:26,370
And we wanna make sure we've got those two compiler

87
00:03:26,370 --> 00:03:27,210
options set.

88
00:03:27,210 --> 00:03:29,100
So we're gonna right click on those three little dots

89
00:03:29,100 --> 00:03:29,933
here on the button.

90
00:03:29,933 --> 00:03:32,490
You wanna select that button and click, and we

91
00:03:32,490 --> 00:03:36,120
wanna make sure that we've got our all warnings enabled on

92
00:03:36,120 --> 00:03:38,913
and our C++ 14 standard on.

93
00:03:39,930 --> 00:03:40,763
Press okay.

94
00:03:42,390 --> 00:03:45,300
Then you wanna come to where it says code completion

95
00:03:45,300 --> 00:03:49,410
and select that and select enable C++ 14 standard.

96
00:03:49,410 --> 00:03:50,243
Apply.

97
00:03:51,690 --> 00:03:52,920
And that's it.

98
00:03:52,920 --> 00:03:54,330
Now what we can do is we can come

99
00:03:54,330 --> 00:03:57,130
to the project again, right click and say

100
00:03:58,200 --> 00:04:00,570
Save as Template.

101
00:04:00,570 --> 00:04:01,623
So I'll select that.

102
00:04:02,760 --> 00:04:04,650
And what's the project name?

103
00:04:04,650 --> 00:04:05,970
This could be anything we want.

104
00:04:05,970 --> 00:04:08,970
We could just say Frank template

105
00:04:08,970 --> 00:04:12,063
or template for course or any name you like.

106
00:04:13,140 --> 00:04:15,290
Rather than that, I'm just gonna say Frank.

107
00:04:17,040 --> 00:04:18,149
Let's see,

108
00:04:18,149 --> 00:04:21,610
g++ console

109
00:04:25,140 --> 00:04:25,973
template.

110
00:04:25,973 --> 00:04:27,240
I think it's pretty picky about spaces,

111
00:04:27,240 --> 00:04:29,670
so I'm just gonna use those dashes.

112
00:04:29,670 --> 00:04:31,590
And it is a console application.

113
00:04:31,590 --> 00:04:33,540
We could that if, if you leave it as console

114
00:04:33,540 --> 00:04:35,250
it'll be in the console group.

115
00:04:35,250 --> 00:04:38,103
I'm actually gonna change that to user template.

116
00:04:39,510 --> 00:04:41,813
And then you can give any description you want.

117
00:04:43,350 --> 00:04:45,300
I'll just say Frank's console template.

118
00:04:48,210 --> 00:04:50,550
That's it. I'll select Okay.

119
00:04:50,550 --> 00:04:52,680
And now we've got a new template that's stored.

120
00:04:52,680 --> 00:04:54,720
So, if I go back to my workspace

121
00:04:54,720 --> 00:04:55,950
and I wanna create a new project.

122
00:04:55,950 --> 00:04:58,200
Now, let me close all this up.

123
00:04:58,200 --> 00:05:01,203
I'm gonna right click and say New Project.

124
00:05:02,280 --> 00:05:03,960
And now you can go down to your templates

125
00:05:03,960 --> 00:05:06,330
and go down to your User templates.

126
00:05:06,330 --> 00:05:07,770
Right here.

127
00:05:07,770 --> 00:05:11,190
And you should see that one we just created right here.

128
00:05:11,190 --> 00:05:13,110
So we can just select that.

129
00:05:13,110 --> 00:05:17,493
Next, I'll just say project one,

130
00:05:18,420 --> 00:05:20,160
select Next.

131
00:05:20,160 --> 00:05:23,250
Keep the defaults for the compilers and finish.

132
00:05:23,250 --> 00:05:25,680
At this point, you can double click here to

133
00:05:25,680 --> 00:05:27,753
make that project the active project.

134
00:05:28,680 --> 00:05:30,900
And we'll look at the main.cpp.

135
00:05:30,900 --> 00:05:34,380
You can see it's the main CPP that we just typed.

136
00:05:34,380 --> 00:05:35,460
Also, if you right click

137
00:05:35,460 --> 00:05:38,490
on the project and you go down to the settings

138
00:05:38,490 --> 00:05:41,010
you can see a code completion is C++ 14.

139
00:05:41,010 --> 00:05:43,380
And the global settings have the appropriate

140
00:05:43,380 --> 00:05:44,793
compiler flags that we need.

141
00:05:45,810 --> 00:05:46,643
That's it.

142
00:05:46,643 --> 00:05:47,973
We'll test this real quick.

143
00:05:49,260 --> 00:05:50,790
Let's run.

144
00:05:50,790 --> 00:05:54,420
Build, and execute and Hello World.

145
00:05:54,420 --> 00:05:55,740
That's it. So now you've got a project

146
00:05:55,740 --> 00:05:56,790
you're all set up.

147
00:05:56,790 --> 00:05:58,620
You can create as many of these as you like.

148
00:05:58,620 --> 00:06:00,503
Tweak the settings as far as you like.

149
00:06:00,503 --> 00:06:03,210
It's really up to you to decide what you wanna do

150
00:06:03,210 --> 00:06:04,260
with the project templates.

151
00:06:04,260 --> 00:06:06,750
But for this course, include iostream.

152
00:06:06,750 --> 00:06:07,890
Give yourself a main.

153
00:06:07,890 --> 00:06:09,720
You may or may not want this line right here,

154
00:06:09,720 --> 00:06:10,950
since you know you're probably gonna get rid

155
00:06:10,950 --> 00:06:12,930
of it anyway when we start writing other code.

156
00:06:12,930 --> 00:06:16,560
But at a minimum, do something like that.

157
00:06:16,560 --> 00:06:17,790
When you create a new project,

158
00:06:17,790 --> 00:06:19,390
you'll be ready to start coding.
