.. index:: single: Getting Started - Third Style; Introduction ============================== Getting Started - Third Style ============================== .. index:: pair: Getting Started - Third Style; Hello World Hello World =========== The next program prints the Hello World message on the screen (std-out). .. code-block:: ring load "stdlib.ring" print("Hello World") .. index:: pair: Getting Started - Third Style; Run the program Run the program =============== to run the program, save the code in a file, for example : hello.ring then from the command line or terminal, run it using Ring .. code-block:: ring ring hello.ring .. index:: pair: Getting Started - Third Style; Create Executable File Create Executable File ====================== Using Ring2EXE we can create executable file for our application .. code-block:: ring ring2exe hello.ring -static The -static option will avoid the need to ring.dll|ring.so|ring.dylib But since the stdlib.ring load libraries like (LibCurl, OpenSSL, MySQL, etc) You will need these libraries! To avoid the need to these libraries (If you don't need stdlib classes) Use stdlibcore.ring instead of stdlib.ring as in the next example .. code-block:: ring load "stdlibcore.ring" print("Hello World") Using stdlibcore.ring You can access the stdlib functions but not the stdlib classes. if you want to use stdlib.ring and distribute your application .. code-block:: ring ring2exe hello.ring -dist -allruntime -noqt -noallegro .. index:: pair: Getting Started - Third Style; Not Case-Sensitive Not Case-Sensitive ================== Since the Ring language is not case-sensitive, the same program can be written in different styles .. tip:: It's better to select one style and use it in all of the program source code .. code-block:: ring LOAD "stdlib.ring" PRINT("Hello World") .. code-block:: ring Load "stdlib.ring" Print("Hello World") .. index:: pair: Getting Started - Third Style; Multi-Line literals Multi-Line literals =================== Using Ring we can write multi-line literal, see the next example .. code-block:: ring Load "stdlib.ring" Print(" Hello Welcome to the Ring programming language How are you? ") Also you can use the \\n to insert new line and you can use #{variable_name} to insert variables values. .. code-block:: ring Load "stdlib.ring" Print( "Hello\nWelcome to the Ring programming language\nHow are you?") .. index:: pair: Getting Started - Third Style; Getting Input Getting Input ============= You can get the input from the user using the getstring() function .. code-block:: ring Load "stdlib.ring" Print("What is your name? ") cName = GetString() Print("Hello #{cName}") .. index:: pair: Getting Started - Third Style; No Explicit End For Statements No Explicit End For Statements ============================== You don't need to use ';' or press ENTER to separate statements. The previous program can be written in one line. .. code-block:: ring Load "stdlib.ring" Print("What is your name? ") cName=getstring() print("Hello #{cName}") .. index:: pair: Getting Started - Third Style; Writing Comments Writing Comments ================ We can write one line comments and multi-line comments The comment starts with # or // Multi-lines comments are written between /* and */ .. code-block:: ring /* Program Name : My first program using Ring Date : 2016.09.09 Author : Mahmoud Fayed */ Load "stdlib.ring" Print("What is your name? ") # print message on screen cName=GetString() # get input from the user print("Hello #{cName}") # say hello! // print("Bye!") .. note:: Using // to comment a lines of code is just a code style.
