WEBVTT 00:00.080 --> 00:05.960 So now you have ubuntu installed on your computer, either with a dual boot or a virtual machine. 00:05.960 --> 00:11.870 And in this lesson, I'm going to show you which tools and ideas are used to program with Ros on ubuntu. 00:11.900 --> 00:14.120 In the end, you use whatever you prefer. 00:14.120 --> 00:19.190 But I just wanted to make this video so that at least you understand what I'm doing in the course. 00:19.190 --> 00:23.990 And if you don't have any preferred IDE, then you can follow those instructions. 00:23.990 --> 00:26.540 And let's start with the terminal tools. 00:26.540 --> 00:28.550 So I'm going to use a terminal of course. 00:28.580 --> 00:36.650 Well this you should know how to open it and use it just in case you have it here in the apps or using 00:36.650 --> 00:38.120 the windows or the command key. 00:38.120 --> 00:44.540 And you just type terminal and you can find it, then I'm going to use a tool which is called Terminator. 00:44.540 --> 00:49.580 And why this is because I can easily split this into multiple terminals. 00:49.580 --> 00:57.530 So to install it you can do sudo apt install terminator in a terminal. 00:58.580 --> 01:04.710 So of course I already have it but you can install it like that, then this is great because, for example, 01:04.740 --> 01:12.150 here I can split this terminal into two terminals horizontally with Ctrl shift and O, and then if I 01:12.180 --> 01:18.720 click on one terminal, I can also split it again horizontally or even vertically with Ctrl shift and 01:18.750 --> 01:19.110 E. 01:19.200 --> 01:22.080 So for example I do that here and I do that here. 01:22.080 --> 01:25.110 This is a common setup I'm going to use in this course. 01:25.110 --> 01:27.900 So now you can see I have four terminals. 01:28.290 --> 01:35.820 You can zoom in one terminal with Ctrl shift and X and then Ctrl shift and X to go back to seeing all 01:35.820 --> 01:39.270 terminals and to exit one terminal for example that one. 01:39.270 --> 01:45.900 So you select it and you can do Ctrl shift and W you can see this terminal is now closed. 01:46.230 --> 01:48.870 So those are the few shortcuts I'm going to use. 01:48.870 --> 01:53.310 I'm not using a lot of them but you can find all of them of course on internet. 01:53.310 --> 01:54.870 So it's very easy to find. 01:54.870 --> 01:56.640 You just type Terminator. 01:56.670 --> 01:57.840 Keyboard shortcuts. 01:57.840 --> 02:03.970 And for example, here I just found a random GitHub page with all the shortcuts you can use. 02:04.600 --> 02:04.930 Great. 02:04.930 --> 02:09.910 So I'm going to use the terminator with multiple terminals and sometimes also just the terminal like 02:09.910 --> 02:10.540 this. 02:10.570 --> 02:11.050 Okay. 02:11.080 --> 02:12.310 It's going to be the same. 02:12.310 --> 02:16.030 Now to write code I'm going to use VS code. 02:16.030 --> 02:17.200 So why vs code. 02:17.200 --> 02:19.780 Because it just works well for what we want to do. 02:19.780 --> 02:23.260 And it also has nice support for Ros. 02:23.260 --> 02:27.010 So to install it in ubuntu you can use snap. 02:27.010 --> 02:37.900 So we are going to do sudo snap install and then code like that followed by dash dash classic. 02:38.650 --> 02:43.450 But the password and it's already installed for me. 02:43.480 --> 02:47.920 Of course I've done it previously but for you it's going to download it and install it. 02:47.920 --> 02:49.210 Then how to start it. 02:49.240 --> 02:54.400 Well you can start it from the terminal using code directly or also from the applications. 02:54.400 --> 02:59.590 Here you type code or vs code and you will find it here. 03:01.090 --> 03:03.070 So let's put it full screen. 03:04.720 --> 03:12.620 And what I'm going to do is go to the extension panel here on the left, and I will search for Ross. 03:12.650 --> 03:18.500 So, Ross, you see I have the first one here. 03:18.500 --> 03:24.110 So that's the Microsoft extension for Ross, which is valid for Ross one and also for Ross two. 03:24.140 --> 03:26.210 So that's the one we're going to use here. 03:26.690 --> 03:28.520 So you can install that one. 03:28.970 --> 03:29.390 Great. 03:29.390 --> 03:34.340 And then if I if I remove this here you can see installed extensions. 03:34.340 --> 03:38.210 I actually have not one but I have a few extensions. 03:38.210 --> 03:40.730 So I have the Ross extension. 03:40.730 --> 03:45.950 But it's also going to install the cplusplus one, the Python one and a few more stuff. 03:45.950 --> 03:47.450 So we have support for Python. 03:47.450 --> 03:51.470 We have support for Cplusplus and for Ross functionalities. 03:51.470 --> 03:53.810 There is also one more I'm going to install. 03:53.810 --> 03:57.950 I'm going to type CMake and I'm going to choose that one. 03:57.950 --> 04:01.970 So cmake by t w x. 04:01.970 --> 04:07.810 This one is just so we get a nice syntax highlighting for CMake files. 04:07.840 --> 04:10.750 Okay, I'm going to install it and that's it. 04:10.750 --> 04:14.140 So you install the Ros extension and that's CMake extension. 04:14.140 --> 04:17.020 And that's all we're going to need here. 04:18.400 --> 04:18.670 Okay. 04:18.670 --> 04:21.820 So in the end you make sure you have Ros and CMake. 04:21.850 --> 04:22.390 Great. 04:22.390 --> 04:29.170 And I'm going to come back to VSCode in this course with how to correctly start it with the Ros project 04:29.170 --> 04:30.910 and then how to set up a few things. 04:30.910 --> 04:36.340 So you have the autocompletion for all the libraries that you need, etc. but for now, that's already 04:36.340 --> 04:37.180 a good start. 04:37.180 --> 04:42.280 So I'm going to use VSCode and also for editing very simple file. 04:42.280 --> 04:44.020 I'm going to use Jedit. 04:44.050 --> 04:44.500 Okay. 04:44.530 --> 04:47.380 So Jedit is a very basic text editor. 04:47.380 --> 04:51.070 You can use whatever you want for example nano or vim. 04:51.100 --> 04:51.400 Okay. 04:51.430 --> 04:53.050 For this course I'm going to use Jedit. 04:53.080 --> 04:57.730 If it's not installed you just install it with sudo apt install git. 04:57.730 --> 05:00.580 But I think it should be installed by default. 05:00.580 --> 05:03.850 And that's pretty much it about the non-raw tools I'm going to use. 05:03.850 --> 05:06.730 So now you can understand everything that I'm doing in this course. 05:06.730 --> 05:08.770 And let's install Ros2.
