NOTE Draw and scribble in GNU Emacs

00:00:00.780 --> 00:00:02.900
Hello. In this video, we will look at

00:00:02.900 --> 00:00:07.167
drawing and scribbling in Emacs using SVG.

00:00:07.167 --> 00:00:10.067
Let's start with `canvas-mode`.

00:00:10.067 --> 00:00:17.539
We will define the width and the height.

00:00:17.540 --> 00:00:19.333
The default is polyline,

00:00:19.333 --> 00:00:23.733
which means you can scribble anything that you want.

00:00:23.733 --> 00:00:30.299
Very handy for taking quick notes.

00:00:30.300 --> 00:00:32.699
Now we will look at

00:00:32.700 --> 00:00:46.333
drawing a triangle using some lines.

00:00:46.333 --> 00:00:57.267
Okay. Now let's draw a circle.

00:00:57.267 --> 00:00:58.900
You can use the mouse to adjust

00:00:58.900 --> 00:01:02.859
the radius of the circle.

00:01:02.860 --> 00:01:04.333
There is some problem with ellipse,

00:01:04.333 --> 00:01:07.939
we will look at it at the end of the video.

00:01:07.940 --> 00:01:11.767
Now let's put up some text,

00:01:11.767 --> 00:01:15.067
a typical "Hello World".

00:01:15.067 --> 00:01:19.879
Size, let's do a 20 font size,

00:01:19.880 --> 00:01:32.359
and we will use the default font family.

00:01:32.360 --> 00:01:37.433
Next, we will look at undoing what we have drawn.

00:01:37.433 --> 00:01:43.067
Just press u for deleting the last drawn object.

00:01:43.067 --> 00:01:45.799
And you can continue pressing

00:01:45.800 --> 00:01:51.959
u for consecutive deletions.

00:01:51.960 --> 00:01:54.533
You can also make a selection of the objects

00:01:54.533 --> 00:01:57.700
on the screen using your mouse and then press u.

00:01:57.700 --> 00:02:02.599
This will delete all the objects in one go.

00:02:02.600 --> 00:02:06.659
Now we are looking at stroke color.

00:02:06.660 --> 00:02:08.633
We will use a brown stroke color

00:02:08.633 --> 00:02:12.879
for drawing our objects.

00:02:12.880 --> 00:02:20.419
Next, let's look at stroke width.

00:02:20.420 --> 00:02:27.979
We will use a width of 5.

00:02:27.980 --> 00:02:41.619
Next, let's fill up the objects with a fill color.

00:02:41.620 --> 00:02:47.159
Now we will look at zoom.

00:02:47.160 --> 00:02:50.119
Use the mouse to select a region and zoom.

00:02:50.120 --> 00:02:54.359
You can also use +, - for zooming in and out.

00:02:54.360 --> 00:03:07.133
Press 0 for resetting the zoom.

00:03:07.133 --> 00:03:14.539
Next, let's save the file,

00:03:14.540 --> 00:03:19.667
and q or Enter for exiting the canvas-mode.

00:03:19.667 --> 00:03:23.760
Now we will open the file in Emacs itself.

00:03:25.220 --> 00:03:26.179
You can see the file,

00:03:26.180 --> 00:03:32.000
you can do Control-c Control-c (`C-c C-c`).

00:03:32.000 --> 00:03:44.419
Finally, we look at ellipse.

00:03:44.420 --> 00:03:46.400
That's all for this video. Thanks!

NOTE SVG Symbols library

00:03:46.400 --> 00:03:48.333
Hello. In this video, we will draw

00:03:48.333 --> 00:03:52.067
schematics using symbols from SVG library in Emacs.

00:03:52.067 --> 00:03:55.000
Press capital L to activate the symbol library

00:03:55.000 --> 00:03:57.867
that you can see on the right hand side,

00:03:57.867 --> 00:04:01.959
and place the symbol on the canvas.

00:04:01.960 --> 00:04:06.639
Let's add another register to this diagram.

00:04:06.640 --> 00:04:11.819
You can press capital R to rotate the symbol.

00:04:11.820 --> 00:04:17.239
Let's place it on the canvas.

00:04:17.240 --> 00:04:31.667
Now we will add a voltage source to the circuit.

00:04:31.667 --> 00:04:33.179
To connect the symbols,

00:04:33.180 --> 00:04:36.967
we will have to use some connecting wires.

00:04:36.967 --> 00:04:39.467
For that, press capital W

00:04:39.467 --> 00:04:46.919
to activate the connection mode.

00:04:46.920 --> 00:04:48.567
Click anywhere on the canvas

00:04:48.567 --> 00:04:53.133
to draw intermediate points, and press Esc

00:04:53.133 --> 00:05:00.033
to exit that particular connection.

00:05:00.033 --> 00:05:16.633
Let's connect other symbols too.

00:05:16.633 --> 00:05:20.139
That's all for this video. Thanks.

NOTE GNU Emacs: A multimedia editor

00:05:20.140 --> 00:05:22.167
Hello. In this video, we will look at

00:05:22.167 --> 00:05:24.933
some basic multimedia editing using Emacs.

00:05:24.933 --> 00:05:27.459
Let's start a media-edit session.

00:05:27.460 --> 00:05:32.000
Let's open a video file.

00:05:32.000 --> 00:05:34.100
The left-hand side is your viewer area,

00:05:34.100 --> 00:05:36.700
and the right-hand side is your track area.

00:05:36.700 --> 00:05:39.667
In the track area, you can use normal Emacs

00:05:39.667 --> 00:05:42.039
text editing movements.

00:05:42.040 --> 00:05:48.167
Now press `C-c r` to refresh the viewer mode

00:05:48.167 --> 00:05:52.767
with the exact time frame.

00:05:52.767 --> 00:05:59.433
Now press SPC to play or pause the video.

00:05:59.433 --> 00:06:03.233
This looks like an interesting point in the video,

00:06:03.233 --> 00:06:11.433
let's track it and split it. Press Enter to do that.

00:06:11.433 --> 00:06:20.733
We will extract some 10 seconds of this video.

00:06:20.733 --> 00:06:23.233
Let's use this.

00:06:23.233 --> 00:06:26.300
Now go here and delete all these lines.

00:06:26.300 --> 00:06:44.133
Let's review our edited clip.

00:06:44.133 --> 00:06:51.833
Looks good! Now press e to export the video.

00:06:51.833 --> 00:06:57.559
Provide an output file name.

00:06:57.560 --> 00:07:04.433
This will use FFmpeg to convert, and you can

00:07:04.433 --> 00:07:16.967
output to any file format supported by FFmpeg.

00:07:16.967 --> 00:07:21.900
Okay. Let's open up shell and view this

00:07:21.900 --> 00:07:57.159
video file in an external video player.

00:07:57.160 --> 00:08:03.367
That's all for this video. Thanks.

NOTE Fill PDF form using GNU Emacs

00:08:03.367 --> 00:08:05.567
Hello. In this video, we will look at

00:08:05.567 --> 00:08:09.760
editing a PDF form using GNU Emacs.

00:08:09.760 --> 00:08:13.840
To start, we have to enable the annotation.

00:08:13.840 --> 00:08:18.533
Then we can use Tab to move forward and Shift+Tab

00:08:18.533 --> 00:08:22.480
to move backwards through the fields.

00:08:22.480 --> 00:08:25.967
To edit a field, we press e.

00:08:25.967 --> 00:08:33.580
So let's edit a text box. We'll call it 'city'.

00:08:33.580 --> 00:08:35.840
Next, we will edit a drop-down.

00:08:35.840 --> 00:08:38.680
Again, press e, and you get a select.

00:08:38.680 --> 00:08:45.833
Use the Minibuffer to select one of the values.

00:08:45.833 --> 00:08:48.500
Let's select 'France'.

08:48.500 --> 00:08:52.180
Now let's edit a radio box.

08:52.180 --> 00:08:55.899
A checkbox or a radio box can be toggled using t.

00:08:55.900 --> 00:08:58.660
You can disable…

08:58.660 --> 00:09:05.140
Now let's save the file, `doc-view-save-form`.

00:09:05.140 --> 00:09:08.360
It will ask for a file name.

00:09:08.360 --> 00:09:13.400
Let's call it `filled1.pdf`. If the file exists,

00:09:13.400 --> 00:09:17.260
it will ask you if you want to overwrite.

09:17.260 --> 00:09:21.460
Now let's verify this new file.

09:21.460 --> 00:09:27.160

NOTE Desktop and window management in GNU Emacs

09:34.900 --> 00:09:37.659
Hello. In this video, we will look at

00:09:37.660 --> 00:09:40.460
desktop and window management in GNU Emacs.

09:40.460 --> 00:09:47.740
We'll start with `task-view`.

09:47.740 --> 00:09:50.467
Top row shows all the desktops,

00:09:50.467 --> 00:09:54.400
and rest of the images are the active windows

00:09:54.400 --> 00:09:59.300
in that particular desktop.

00:09:59.300 --> 00:10:09.159
You can tap to select

00:10:09.160 --> 00:10:13.320
and double tap to activate a particular window.

00:10:13.320 --> 00:10:16.767
You can use m to move selected windows

00:10:16.767 --> 00:10:25.099
to any of the desktops at the top.

00:10:25.100 --> 00:10:29.320
Let's check the third desktop.

00:10:29.320 --> 00:10:49.980
Let's bring it back to the second desktop.

10:49.980 --> 00:10:51.300
The best part,

10:51.300 --> 00:10:54.799
you can select multiple windows

00:10:54.800 --> 00:10:59.979
and form a group by pressing g.

00:10:59.980 --> 00:11:04.867
Then you can select any of the windows

00:11:04.867 --> 00:11:07.639
in this group to activate the complete group.

00:11:07.640 --> 00:11:10.439
That's all for this video. Thanks.

NOTE Screen mirroring in GNU Emacs

00:11:10.440 --> 00:11:12.433

00:11:12.433 --> 00:11:14.279
screen mirroring using GNU Emacs.

00:11:14.280 --> 00:11:18.779
Run `wfd`. Select an interface.

00:11:18.780 --> 00:11:20.967
Now it will scan for all the available devices

00:11:20.967 --> 00:11:24.800

00:11:24.800 --> 00:11:30.399
I'll select my TV, which is an LG WebOS TV.

00:11:30.400 --> 00:11:38.720
If you don't decline, it will start streaming.

00:11:38.720 --> 00:11:45.140
Let's change some buffer to check the visuals.

11:45.140 --> 00:11:50.219
To terminate the session, just click on quit.

00:11:50.220 --> 00:11:53.033

NOTE GNU Emacs as a lightweight IDE (CEDET Semantic): Java - Generate getter/setter

00:14:35.233 --> 00:14:37.633
Hello. In this video, we will look at

00:14:37.633 --> 00:14:41.659
generating getters and setters in Java using Emacs.

00:14:41.660 --> 00:14:46.233
We will run `srecode-getset-dialog`.

00:14:46.233 --> 00:14:48.767
We will get an option to select particular fields,

00:14:48.767 --> 00:14:51.833
you can expand and collapse.

00:14:51.833 --> 00:14:54.100
You can select all or deselect all,

00:14:54.100 --> 00:14:56.386
or you can choose any particular getter.

00:14:56.386 --> 00:15:02.633
So let's do protected version of this. Here you go.

00:15:02.633 --> 00:15:06.067
If you want to generate for other fields,

00:15:06.067 --> 00:15:08.300
you can re-run it.

00:15:08.300 --> 00:15:11.267
You can check the one that you have already

00:15:11.267 --> 00:15:13.100
generated is not there.

00:15:13.100 --> 00:15:22.300
Now select all, and you can see rest of the

00:15:22.300 --> 00:15:23.933
getters and setters have been generated.

00:15:23.933 --> 00:15:26.133
That's all for this video. Thanks.

NOTE C Rename symbols

00:16:11.640 --> 00:16:13.833
Hello. In this video, we will look at

00:16:13.833 --> 00:16:17.633
renaming method across multiple files in a project.

00:16:17.633 --> 00:16:24.639
Let's start with `semantic-symref-symbol`.

00:16:24.640 --> 00:16:26.800
Now we have the references.

00:16:26.800 --> 00:16:35.399
Let's use the menu to open all these occurrences.

00:16:35.400 --> 00:16:38.433
To rename it, we have to use

00:16:38.433 --> 00:16:41.919
"Rename Symbol in Open hits."

00:16:41.920 --> 00:16:46.439
Let's rename it to underscore 1 (`_1`).

00:16:46.440 --> 00:16:57.719
We will verify it by compiling the project.

00:16:57.720 --> 00:17:00.300
Let's open the `*Messages*` buffer to see the results

00:17:00.300 --> 00:17:04.167
more clearly. No errors.

00:17:04.167 --> 00:17:07.639
That's all for this video. Thanks.

NOTE SQL (offline)

00:17:07.640 --> 00:17:09.733
Hello. In this video, we will look at

00:17:09.733 --> 00:17:12.439
SQL editing with Semantic.

00:17:12.440 --> 00:17:16.619
We will define a schema in this SQL document.

00:17:16.620 --> 00:17:27.000
Let's create a table.

00:17:27.000 --> 00:17:30.267
We get already existing tables

00:17:30.267 --> 00:17:38.533
in the current document.

00:17:38.533 --> 00:17:57.033
It also supports auto-completion of some keywords.

00:17:57.033 --> 00:18:00.900
Now we can do some queries on the tables.

00:18:00.900 --> 00:18:03.333
We have `SELECT` as the keyword or the SQL,

00:18:03.333 --> 00:18:06.833
so we will select the SQL.

00:18:06.833 --> 00:18:13.559
Here we have all the tables existing in this schema.

00:18:13.560 --> 00:18:25.633
We can also use an alias for completions.

00:18:25.633 --> 00:18:31.267
Now let's look at a more complex example.

00:18:31.267 --> 00:18:43.367
We will try to do a join on two tables.

00:18:43.367 --> 00:19:06.600
Let's add a `WHERE` clause.

00:19:06.600 --> 00:19:23.333
Next, let's do insert.

00:19:23.333 --> 00:19:27.967
You can just click on Tab to go to the next field.

00:19:27.967 --> 00:19:30.700
Let's fill in the columns.

00:19:30.700 --> 00:19:32.667
And do a Tab to go to the values

00:19:32.667 --> 00:19:37.000
and add the corresponding values.

00:19:37.000 --> 00:19:48.033
Finally, an update.

00:19:48.033 --> 00:20:00.700
Now we will try to delete this

00:20:00.700 --> 00:20:07.333
with a `WHERE col11 = 4`.

00:20:07.333 --> 00:20:16.267
Lastly, let's try dropping the table.

00:20:16.267 --> 00:20:21.867
That's all for this video. Thanks.
