| 00:01 | Welcome to the Spoken Tutorial on Snippets in gedit Text editor. |
| 00:08 | In this tutorial, we will learn how to Use default Snippets |
| 00:13 | Add new snippets |
| 00:15 | Delete snippets |
| 00:17 | Highlight matching brackets and Document Statistics |
| 00:22 | To record this tutorial, I am using: Ubuntu Linux 14.04 operating system gedit Text editor 3.10 |
| 00:33 | To follow this tutorial, you should have working knowledge of any operating system. |
| 00:39 | What are snippests ? |
| 00:41 | Snippets are lines of text or source code that are used frequently while writing a program. |
| 00:49 | It allows the user to avoid repetitive typing. |
| 00:54 | Snippets is one of the default plugins in gedit Text editor. |
| 00:59 | Let's see how we can create and use Snippets. |
| 01:04 | Let's open the gedit Text editor. |
| 01:08 | First we need to enable the Snippet plugin. |
| 01:12 | From the Main menu, click Edit and Preferences. |
| 01:17 | In the Plugin tab, scroll down and check the Snippets box. |
| 01:23 | Click Close. |
| 01:25 | Let us write a 'C' program to check whether a given number is positive or negative. |
| 01:32 | First Let us save the file as NumCheck.c |
| 01:39 | Pause this tutorial and type this code in your gedit Text editor. |
| 01:44 | When you have finished typing, place your cursor on the next line. |
| 01:49 | Now type the word If and press the Tab key. |
| 01:54 | Can you see the structure of the If statement automatically inserted here? |
| 02:00 | Notice that the cursor is on the word condition, by default. |
| 02:05 | Type num==0. |
| 02:09 | The word condition is overwritten. |
| 02:12 | We can see the open curly braces andend braces are inserted automatically. |
| 02:18 | This is because we have added the plugin called Intelligent text completion in the previous tutorial. |
| 02:26 | Type printf open brackets double quotes. |
| 02:31 | Notice the end double quotes are also inserted automatically. |
| 02:36 | Recall that one of the features of Intelligent Text Completion is “Auto close brackets and quotes”. |
| 02:44 | Now type as shown here. |
| 02:48 | Now, from the Main menu, select Tools and Manage Snippets. |
| 02:54 | The Manage Snippets dialog box appears. |
| 02:56 | On the left side panel, scroll down and select 'C'. |
| 03:02 | Click on the triangle sign next to it. |
| 03:06 | The list of all the Snippets for 'C' are listed here. |
| 03:11 | Click on the If snippet. |
| 03:14 | In the top right panel, you can see the complete syntax for the 'If' statement in 'C' language. |
| 03:21 | Look at the Tab Trigger field at the right bottom. It is displayed as 'If', by default. |
| 03:30 | So, by typing 'If' and pressing the Tab key, the complete 'If' statement gets inserted. |
| 03:38 | Let us see one more snippet called else if. |
| 03:42 | On the left hand side, click on the else if snippet under 'C'. |
| 03:48 | You can see the syntax for this on the top right panel. |
| 03:53 | Note the Tab trigger as 'elif'. |
| 03:56 | Click Close. |
| 04:00 | Let us see how to use this snippet in our program. |
| 04:04 | Type elif and press tab. |
| 04:09 | You can see that the syntax for 'else if' is inserted here. |
| 04:14 | Type the program code as shown here. |
| 04:19 | So, with the help of Snippets, we can avoid repetitive typing in our source code. |
| 04:26 | Next, we will see how to create our own Snippet. |
| 04:30 | Now, from the Main menu, click Tools and Manage snippets. |
| 04:38 | In the Manage Snippets dialog box that appears, select C. |
| 04:42 | At the bottom left of the window, click the plus icon to create a new snippet. |
| 04:49 | Type “HelloWorld” and press Enter. |
| 04:53 | Then click on the Edit panel. |
| 04:56 | Type the following code. This is a simple basic program in 'C'. |
| 05:02 | In the Tab trigger field, type “hello”. This is the shortcut keyword used in the editor. |
| 05:10 | Click Close. |
| 05:13 | Open a new document in the gedit Text editor. |
| 05:18 | Save the file as helloworld.c . |
| 05:22 | If you don't save the file with '.c' extension, the snippets will not work. |
| 05:29 | It will consider the file as a text file, not a 'c' program file. |
| 05:35 | Type “hello” and press the Tab key. |
| 05:39 | The text that we typed in the ‘HelloWorld’ snippet is inserted here. |
| 05:45 | This is how we create and use a custom snippet. |
| 05:50 | Next, let us see how to delete a snippet. |
| 05:54 | From the Main menu, click Tools and Manage Snippets. |
| 05:59 | In the snippet list, click C. |
| 06:02 | Click on the snippet ‘HelloWorld’ which we have created. |
| 06:07 | At the bottom left of the window, click the minus icon to delete a snippet. |
| 06:13 | The snippet is deleted. |
| 06:16 | Now, locate the snippet ‘While loop’ from the list and select it for deletion. |
| 06:23 | We can see here that the delete icon is disabled. |
| 06:28 | This means we can only delete the snippets which we have created, and not the default ones. |
| 06:35 | Click Close. |
| 06:37 | Let us switch back to NumCheck.c tab. |
| 06:42 | In this 'C' program, you can see brackets of different types. |
| 06:47 | Sometimes, we may lose track of the closing bracket that matches the opening bracket. |
| 06:54 | Let us see how to highlight the matching brackets. |
| 06:58 | From the Main menu, click Edit and Preferences. |
| 07:03 | In the View tab, check the Highlight matching brackets box. |
| 07:07 | Click Close. |
| 07:09 | Now, place the cursor on the open curly braces at the start of the program. |
| 07:15 | Notice that the last closed curly braces is highlighted immediately. |
| 07:22 | Place your cursor on the second open curly braces. |
| 07:27 | Notice that the second last closed curly braces is highlighted in gray color. |
| 07:33 | This is good way to keep track of the brackets in a program. |
| 07:38 | It helps ensure that all open brackets have the corresponding closing brackets. |
| 07:44 | Next we will learn about the Document Statistics feature. |
| 07:49 | Document Statistics plugin shows the various statistics related to the current document. |
| 07:56 | It shows information such as: ,Number of words ,Number of lines ,Number of characters ,Number of non-space characters ,Size of the file in bytes |
| 08:10 | Let us switch back to gedit Text editor. |
| 08:14 | From the Main menu, click Edit and Preferences. |
| 08:19 | Click on the Plugins tab. |
| 08:22 | Scroll down to see Document Statistics option. |
| 08:26 | If the Document Statistics plugin is not enabled then check it. |
| 08:32 | Click Close. |
| 08:34 | From the Main menu, select Tools and Document Statistics. |
| 08:39 | The Document Statistics dialog box opens. |
| 08:43 | It displays the statistics including lines, words, characters and bytes in the document NumCheck.c |
| 08:53 | In the file NumCheck.c, change the words as shown. |
| 09:01 | Now, from the Document Statistics dialog box, click on Update. |
| 09:07 | Notice, that the information has been updated to reflect the changes we made. |
| 09:12 | Click Close. |
| 09:15 | This feature is very useful when a document is required to stay within certain number of words. |
| 09:22 | This brings us to the end of this tutorial. |
| 09:25 | Let us summarise. |
| 09:27 | In this tutorial, we learnt how to: Use default snippets |
| 09:32 | Add new snippets |
| 09:34 | Delete snippets |
| 09:36 | Highlight matching brackets aned Document Statistics |
| 09:41 | Here is an assignment for you. |

| 09:49 | Enter the complete company address in the edit panel |
| 09:53 | In the Tab trigger field, enter the shortcut key as company |
| 09:58 | Open a new document and use the snippet. |
