Variables

Variables can be declared using nodu guru.

  nodu guru b = "two";
  nodu guru c = 15;
  a = a + 1;
  b = 21;
  c *= 2;

Types

Numbers and strings are like other languages. Null values can be denoted using nalla. nija and sullu are the boolean values.

namskara guru
  nodu guru a = 10;
  nodu guru b = 10 + (15*20);
  nodu guru c = "two";
  nodu guru d = 'ok';
  nodu guru e = nalla;
  nodu guru f = nija;
  nodu guru g = sullu;
aythu guru

Built-ins

Use helu guru to print anything to console.

namskara guru
  helu guru "Hello World";
  nodu guru a = 10;
  {
    nodu guru b = 20;
    helu guru a + b;
  }
  helu guru 5, 'ok' , nija , sullu;
aythu guru

Conditionals

Gurulang supports simple if else construct , guru eega block will execute if condition is nija and illandre guru block will execute if condition is sullu.

namskara guru
  nodu guru a = 10;
  guru eega (a < 25) aadre{
   helu guru "a is less than 25";
  } illandre guru {
   helu guru "a is greater than or equal to 25";
  }
aythu guru

Loops

Statements inside guru ellivargu blocks are executed as long as a specified condition evaluates to nija. If the condition becomes sullu, statement within the loop stops executing and control passes to the statement following the loop. Use saak bidu guru to break the loop and mundhe nodu guru to continue within loop.

namskara guru
  nodu guru a = 0;
  guru ellivargu (a < 10) {
   a += 1;
   guru eega (a == 5) aadre{
    helu guru "olaginda helu guru ", a;
    mundhe nodu guru;
   }
   guru eega (a == 6) aadre{
    saak bidu guru;
   }
   helu guru a;
  }
  helu guru "done";
