Lists

GoMelan provides easy-to-use and define lists.

Simple Example

// Define a String as a list of Char
name: String = ['G', 'u', 'i', 'l', 'l', 'a', 'u', 'm', 'e'];
description: String = [' ', 'e', 's', 't', ' ', 'b', 'e', 'a', 'u'];
phone: [Int] = [0, 7, 8, 3, 8, 7, 1, 6, 0, 8];

Strings are considered in GoMelan as list of Char type. Therefore String <-> [Char]

Main Function

The main function in GoMelan demonstrates the use of various list operations and conversions.

fn main() -> Int
{
    // Declare variables
    name: String = ['G', 'u', 'i', 'l', 'l', 'a', 'u', 'm', 'e'];
    description: String = [' ', 'e', 's', 't', ' ', 'b', 'e', 'a', 'u'];
    phone: [Int] = [0, 7, 8, 3, 8, 7, 1, 6, 0, 8];
    height: Float = 1.73;
    birthDate: String = "11012003";

    // Concatenate two strings
    nameAndDescription: String = name + description;
    
    // Get a character at a specific index
    firstLetter: Char = name[0];

    // Get the length of a list
    nameLen: Int = len(name);

    // Convert a Float to an Int
    heightInt: Int = floatToInt(height);

    // Convert a String to an Int
    birthDateInt: Int = stringToInt(birthDate);

    return 0;
}

Results

Here are the results for each variable after executing the code:

nameAndDescription = "Guillaume est beau"
firstLetter = 'G'
nameLen = 9
heightInt = 1
birthDateInt = 11012003

These results demonstrate the concatenation of strings, accessing a character at a specific index, obtaining the length of a list, and converting both a Float and a String to Int.
