Hi, Community!

Have a question for general discussion. 

In ObjectScript we have cls for classes and mac code, which both compile into int code. 

Is there any reason when you use mac instead of cls  for non-persistent classes?

For me the benefits for cls are:

1. Inheritance and other OOP features

2. Auto-documented code 

For mac one visible benefit is easier call in terminal:

do method^Utils(p1,p2)

vs

do ##class(Package.Utils).method(p1,p2)

What is your choice and why?

Hi Community!

Coding guidelines discussion. Consider you have For with one command in the cycle. Here are the options:

One

For i=1:1:1000 set ^Test(i)=""

Two

For i=1:1:1000 {
 set ^Test(i)=""
}

Same for the "If":

if a set b=a

or

if a {
 set b=a
}

Your choice? Or maybe even other options? 

You will receive a string of comma-separated integers whose elements have both a negative and a positive value, except for one integer that is either only negative or only positive, our challenge will be to find that integer. As usual shortest solution wins.

##Input "1,-1,2,-2,3"

##Output 3

3 has no matching negative appearance

##Note

• The only-positive or only-negative integer may appear more than once
• Use this code to check the result length
• You also can use this test case here

Hello community,

Yesterday was celebrated the "World Medical Ethics Day" https://www.ama.com.au/media/wma-medical-ethics-day

We could celebrate it with a programming quiz or challenge:

DESCRIPTION:

Deoxyribonucleic acid (DNA) is a chemical found in the nucleus of cells and carries the "instructions" for the development and functioning of living organisms.

If you want to know more: http://en.wikipedia.org/wiki/DNA

In DNA strings, symbols "A" and "T" are complements of each other, as "C" and "G".

Let's have a round of CodeGolf!

As usual the goal is to write the shortest solution for a specified problem.

Today we have one of the classics: FizzBuzz.

Write a program that prints the numbers from 1 to 100.

But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”.

For numbers which are multiples of both three and five print “FizzBuzz”

Hi Developers!

Often we need to use relatively small arrays with constants, static arrays in algorithms, etc where we need to do something with each element of an array. There are several ways to deal with it in ObjectSctipt. 

Previously I used to use globals, locals, PPG for this but not so long time ago figured out that %List is a way too handy.

Indeed, suppose we have an array of months and need to set up and use it in our code.

We're back with a code golf!

You will receive a string. Each word in the string will contain a number. This number is the position that word should have in the sentence. If the input string is empty, return an empty string. The output can only be in words, without the given numbers.

##Input "i2s T1his Te4st a3"

##Output This is a Test

Let's do a round of code golf! Last one was very popular!

The Chinese zodiac is a repeating cycle of 12 years, with each year being represented by an animal and an element that changes every 2 years.
The animals are: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog and Pig.
The elements are: Wood, Fire, Earth, Metal and Water.
Your task is to write a function that receives a year, and returns the element and the animal that year represent.
Let's use the year 1924 as start point, in the Chinese zodiac the element was Wood and the animal was Rat.

A quine is a computer program which takes no input and produces a copy of its own source code as its only output.

Wikipedia.

How about a fun challenge?

The task is to write a quine in InterSystems ObjectScript. It can be a class, or a method, or a routine, or just a line to be executed in a terminal. You decide!

Here's some resources you might consider useful:

• $TEXT
• XECUTE
• $XECUTE
• %Compiler.UDL.TextServices:GetTextAsString
• %Dictionary package
• Indirection

Hard mode: do not use source code access functions.

Here's my (extremely uninspired, I know) attempt:

Class User.Quine
{

/// do ##class(User.Quine).Test()
ClassMethod Test()
{
    set sc = ##class(%Compiler.UDL.TextServices).GetTextAsString($namespace, $classname(), .str)
    write str
}

}

It produces this output:

How many different ways of producing a quine are there in ObjectScript?

Leet (or "1337"), also known as eleet or leetspeak, is a system of modified spellings used primarily on the Internet. It often uses character replacements in ways that play on the similarity of their glyphs via reflection or other resemblance. Additionally, it modifies certain words based on a system of suffixes and alternate meanings. There are many dialects or linguistic varieties in different online communities. Wikipedia

You'll have to translate a string into a LeetSpeak. As usual shortest solution wins.

New Year, new Code Golf!

You will receive a positive integer for the number of floors. Your challenge will build a pyramid with a "#" character. As usual, the shortest solution wins.

##Input 3

##Output

also a valid output

To celebrate programming day, could we create solutions for a little challenge?

We have the following statement:

Given a string of words, return the length of the shortest word(s).

String will never be empty and you do not need to account for different data types.

Some test made in Java would be:

import org.junit.Test;

import java.util.Arrays;
import java.util.Random;
import java.util.stream.Collectors;

import static org.junit.Assert.assertEquals;

Have you ever seen those vaccum compressed towels, that look like a pill and after you add water became a towel?

That's our challenge for today. As usual shortest solution wins.

Task

You will receive an integer number and you will return a new number where each digit is repeated a number of times equals to its value.

Input:

42

Output:

444422

Note:

• Input is only made of digits [0-9]
• Zero returns an empty string
• Use this code to check the result length
• You also can use this test case here

 It's time for a Code Golf round!

Isogram 

A word or phrase that has no repeating letters, consecutive or non-consecutive.

Implement a method that checks if the received string is an isogram or not.
Assume the empty string is an isogram. 
Ignore the letter case.

Allowed inputs: A-Z, a-z.

As usual, the shortest solution wins!

New month, new code golf!

You will receive a string with a label code with numbers and letters. Our challenge is to check if this code begins with 1, 2, or 3 and ends with A, B, C, S, or R. It should return true(1) if so or return false(0) otherwise. As usual shortest solution wins.

##Input "198739A79D9R"

##Output 1

##Note

• The string only contains numbers and upper-case letters. No other special characters.
• Use this code to check the solution length
• You also can use this test case here

Hello community,

Because of recently the "Green Game Jam" has been celebrated as a part of a mission to improve environmental awareness, as the following quote explains: https://playing4theplanet.org/about

"UNEP has been working with the gaming industry to explore how, through their massive reach, they can inspire young people to learn and act in support of the environment. The gaming industry reaches 1 in 3 people on the planet and has a platform with unprecedented influence. How can this rapidly expanding media platform be harnessed to deliver on the Sustainable Development Goals?

Hello, community

To celebrate that this week is "International Week of Deaf People 2022" , https://wfdeaf.org/iwdeaf2022/

Could we do a small challenge?

The statement is:

Task

Give you two strings: s1 and s2. If they are opposite, return true; otherwise, return false. Note: The result should be a boolean value, instead of a string.

The opposite means: All letters of the two strings are the same, but the case is opposite. you can assume that the string only contains letters or it's a empty string. Also take note of the edge case - if both strings are empty then you should return false/False.

Hello,

I was wondering if there is a way, or what is your recommended way to generate, or develop some kind of deep interest or even some joy, love, or excitement towards coding, programming, software developing. Specifically for people aged between 20 and 30 years old.

I am aware of some programming games like the following ones:

Hey everyone.

As I have been working with IRIS (nee Caché) for some time now, I decided to take a look at how I manage things like functions and scripts that may not belong to a single namespace or environment, but should still have a home.

I have taken to creating a github repo where I can keep track of a single .cls of "general functions" that I can then drop into an environment when required.
