Time' Narration


00.00 Hello Rubyપર ના સ્પોકન ટ્યુટોરીયલમા તમારુ સ્વાગત છે!


00.04 આ ટ્યુટોરીયલમા આપણે શીખીશું
00.06 Ruby શું છે ?
00.08 લક્ષણો
00.09 RubyGems' અને 'Ruby પર મદદ
00.12 સંસ્થાપન
00.13 Ruby કોડ રન કરવું.


00.15 કમેન્ટ કરવું.
00.16 puts અને print વચ્ચે તફાવત.


00.19 અહીં આપણે વાપરી રહ્યા છે Ubuntu Linux version 12.04 Ruby 1.9.3
00.27 આ ટ્યુટોરીયલ અનુસરવા માટે તમે ઇન્ટરનેટ સાથે જોડાયેલ હોવા જ જોઈએ.
00.30 ' Linuxમા તમને Terminal અને Text editor વાપરવાનું જ્ઞાન હોવું જરૂરી છે .
00.37 હવે હું સમજાવીશ Ruby શું છે ?.
00.40 Ruby એ object-oriented, અર્થઘટન સ્ક્રિપ્ટીંગ ભાષા છે.
00.44 તે ગતિશીલ, ઓપન સોર્સ પ્રોગ્રામિંગ ભાષા છે.
00.48 તે એક ભવ્ય વાક્યરચના છે, જે વાંચવા અને લખવા માટે સરળ છે


00.54 ચાલો હવે Rubyના અમુક લક્ષણો જોઈએ.


00.57 Ruby ખૂબ સુવાહ્ય છે.
00.59 'Ruby' પ્રોગ્રામ કોઈપણ ઓપરેટિંગ સિસ્ટમમાં ચાલે છે.
01.04 Smalltalk, BASIC અથવા Python ની જેમ Rubyમાં વેરીએબલો ના દેતા ટાઈપ બથી હોતા.
01.11 તે આપમેળે મેમરી સંચાલન ને આધાર આપે છે.
01.14 'Ruby' મુક્ત બંધારણ ભાષા છે.
01.17 તમે કોઇપણ લાઇન અને સ્તંભ માંથી પ્રોગ્રામ લખવાનું શરૂ કરી શકો છો.
01.21 'Ruby' ઈન્ટરનેટ અને ઇન્ટ્રા નેટ એપ્લિકેશન્સ વિકસાવવા માટે ઉપયોગ થાય છે.


01.26 'RubyGems 'Ruby ના મહત્વ ના લક્ષણમાનું એક છે.


01.36 It provides a standard format for distributing Ruby programs and libraries.


01.42 You can create and publish your own gems.
01.46 For more information on RubyGems visit the following link.



01.51 To get more help on Ruby you can visit the links shown.
01.55 You can install Ruby using the Ubuntu Software Centre.
01.59 For more information on Ubuntu Software Centre, please refer to the Ubuntu Linux Tutorials on this website.


02.07 Other methods for installing Ruby are as shown in this slide.
02.12 'Ruby code can be executed in 3 ways
02.16 Command line
02.17 Interactive Ruby
02.19 As a 'file


02.20 We will go through each method of execution.


02.23 First let us see how to execute the Hello World code from command line.
02.28 Open a terminal by pressing the Ctrl, Alt and T keys simultaneously.


02.33 A terminal window appears on your screen.
02.37 Type the command
02.38 ruby space hyphen e space within single quotes puts space then within double quotes Hello World and


02.50 Press Enter.
02.53 We get the output as Hello World.
02.56 puts command is used to print the output on the terminal.
03.00 The hyphen e flag allows only a single line of code to be executed.
03.06 Multiple hyphen e flags can be used to execute multiple line commands.


03.11 Lets try this out
03.13 Now press the up Arrow key to get the previous command and
03.18 Type space hyphen e space within single quotes puts space 1+2 and


03.30 Press Enter.
03.32 We get the output as Hello World and 3.


03.36 Let's switch back to our slide
03.38 We will now learn about Interactive Ruby.


03.42 Interactive Ruby allows the execution of Ruby commands with immediate response.


03.48 You can run Ruby statements and examine the output and return values.


03.53 For older version of Ruby, install irb separately.
03.57 Now let us execute our Ruby code through irb. Go to the terminal


04.03 Typeirb and Press Enter
04.06 to launch the Interactive Ruby
04.09 Type puts space within double quotes Hello World and press Enter.
04.19 We get the output as Hello World.
04.22 And We get the return value as nil.


04.25 To exit from irb type exit and press Enter.
04.31 You can also run Ruby program from a file.


04.34 You can use any text editor of your choice to write the code.
04.39 I am using gedit text editor. Let me switch to gedit text editor
04.45 Now, type puts space within double quotes Hello World
04.54 Lets learn how to add multiple line or block comments.
04.59 Before the puts command
05.01 Type, equal to begin and press Enter
05.06 'Equal to begin is used to start the comment.
05.10 Type the comments that you wish to add.


05.13 I will type My first Ruby program
05.20 and Press Enter
05.22 Then type This code will print helloworld and Press Enter
05.30 Now type equal to end
05.32 equal to end is used to end the multiple line comments.
05.37 Comments are useful to understand the flow of program.
05.41 It is useful for documentation.
05.45 Now, let us save the file by clicking on the Save button.


05.50 It is a good practice to save the file frequently.
05.53 The Save As dialog box appears on your screen.
05.57 Browse the location where you want to save the file.
06.01 On 'Desktop, I will create a folder named rubyprogram.


06.06 We will save the file inside this folder.
06.10 In the Name text-box, type the name that you wish to add.
06.14 I will type hello.rb
06.17 Dot rb extension is given to a Ruby file
06.21 Then click on Save button to save the file. So the file is saved now.
06.28 To execute the code, go to the terminal.
06.32 Lets clear the terminal first.
06.35 Make sure that you are in the directory where your Ruby file is present.
06.39 Remember that we are in the home directory. We need to go to the subdirectory rubyprogram.
06.47 To do so, type cd space Desktop/rubyprogram and press Enter.
07.00 Let's execute the file . Type ruby space hello dot rb and press Enter
07.10 We get the output HelloWorld.
07.13 Now let me demonstrate the difference between puts and print statement.


07.18 We will try this out using irb
07.22 Before that we need to go back to the home directory.To do so type cd and press Enter
07.31 Now type irb and Press Enter to launch the Interactive Ruby.
07.39 Type puts space within double quotes Hello comma within double quotes World
07.50 Here comma is used to join the two puts command together.
07.55 Now press Enter.
07.57 We get the output Hello World, but on separate lines.
08.03 Now let's try the same thing with print.


08.06 Press up arrow key to get the previous command
08.09 Replace puts with print and Press Enter.
08.14 We get the output as Hello World but on the same line.
08.19 The keyword puts adds a newline to the end of the output. The keyword print does not.
08.27 The keyword print outputs only what we have provided.
08.31 This brings us to the end of this Spoken Tutorial. Let us switch back to our slides.
08.37 In this tutorial we have learnt
08.39 About Ruby
08.41 Installation
08.42 Execution of Ruby code
08.44 Adding multiple comments using =begin and =end


08.50 Difference between puts and print
