Syntax At A Glance

NOTE

There is a more detailed documentation of the language here.

Nuru, although still in its early stage, intends to be a fully functional programming language, and thus it has been baked with many features.

Defining A Variable

You can define variables like this:

x = 2;
y = 3;

andika(x*y) // output is 6

You can also use the fanya keyword to define a variabe:

fanya x = 3

Note that fanya keyword is OPTIONAL

Comments

Nuru supports both single line and multiple line comments as shown below:

// Single line comment

/*
Multiple
Line
Comment 
*/ 

Arithmetic Operations

For now Nuru supports +, -, /, * and %. Nuru also provides precedence of operations using the BODMAS rule:

2 + 2 * 3 // output = 8

2 * (2 + 3) // output = 10

Types

Nuru has the following types:

Functions

This is how you define a function in Nuru:

jumlisha = unda(x, y) {
        rudisha x + y
    }

andika(jumlisha(3,4))

Nuru also supports recursion:

fibo = unda(x) {
	kama (x == 0) {
		rudisha 0;
	} au kama (x == 1) {
			rudisha 1;
	} sivyo {
			rudisha fibo(x - 1) + fibo(x - 2);
	}
}

If Statements

Nuru supports if, elif and else statements with keywords kama, au kama and sivyo respectively:

kama (2<1) {
    andika("Mbili ni ndogo kuliko moja")
} au kama (3 < 1) {
    andika ("Tatu ni ndogo kuliko moja")
} sivyo {
    andika("Moja ni ndogo")
}

While Loops

Nuru's while loop syntax is as follows:

i = 10

wakati (i > 0) {
	andika(i)
	i--
}

Arrays

This is how you initiliaze and perform other array operations in Nuru:

arr = []

// To add elements

sukuma(arr, 2)
andika(arr) // output = [2]
// Add two Arrays

arr2 = [1,2,3,4]

arr3 = arr1 + arr2

andika(arr3) // output = [2,1,2,3,4]

// reassign value

arr3[0] = 0

andika[arr3] // output = [0,1,2,3,4]

// get specific item

andika(arr[3]) // output = 3

Dictionaries

Nuru also supports dictionaries and you can do a lot with them as follows:

mtu = {"jina": "Mojo", "kabila": "Mnyakusa"}

// get value from key 
andika(mtu["jina"]) // output = Mojo

andika(mtu["kabila"]); // output = Mnyakusa

// You can reassign values

mtu["jina"] = "Avicenna"

andika(mtu["jina"]) // output = Avicenna

// You can also add new values like this:

mtu["anapoishi"] = "Dar Es Salaam"

andika(mtu) // output = {"jina": "Avicenna", "kabila": "Mnyakusa", "anapoishi": "Dar Es Salaam"}

// You can also add two Dictionaries

kazi = {"kazi": "jambazi"}

mtu = mtu + kazi

andika(mtu) // output = {"jina": "Avicenna", "kabila": "Mnyakusa", "anapoishi": "Dar Es Salaam", "kazi": "jambazi"}

For Loops

These can iterate over strings, arrays and dictionaries:

kwa i ktk "habari" {
    andika(i)
}
/* //output
h
a
b
a
r
i
*/

Getting Input From User

In Nuru you can get input from users using the jaza() keyword as follows:

jina = jaza("Unaitwa nani? ") // will prompt for input

andika("Habari yako " + jina)

How To Run

Using The Intepreter:

You can enter the intepreter by simply running the nuru command:

nuru
>>> andika("karibu")
karibu
>>> 2 + 2
4

Kindly Note that everything should be placed in a single line. Here's an example:

>>> kama (x > y) {andika("X ni kubwa")} sivyo {andika("Y ni kubwa")}

Running From File

To run a Nuru script, write the nuru command followed by the name of the file with a .nr or .sw extension:

nuru myFile.nr
