Time	Narration
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
