Emojicode

If unable to view some emoji below, your operating system might not be the latest. Rather than update your operating system just for this test, try viewing this page on your phone or another computer instead, albeit in accordance with the course’s policy on academic honesty.

Odds are you’ll have to teach yourself a new programming language some day, perhaps even installing some software for it. Let’s prepare you for that day!

Emojicode is “an open-source, full-blown programming language consisting of emojis.” Here, for instance, is a now-familiar program, implemented in Emojicode:

🏁 🍇
  😀 🔤hello, world🔤❗️
🍉

Installing

In order to compile that program from Emojicode to machine code, you’ll need a compiler, emojicodec. Here’s how to install it VS Code:

Install some “dependencies” that Emojicode’s compiler requires:
```
 sudo apt install -y libncurses5 rsync
```

Download a “gzipped tarball” (which is similar to a Zip file) of Emojicode’s installer:

 wget https://github.com/emojicode/emojicode/releases/download/v1.0-beta.2/Emojicode-1.0-beta.2-Linux-x86_64.tar.gz

Decompress that gzipped tarball:

 tar -xzf Emojicode-1.0-beta.2-Linux-x86_64.tar.gz

Change into the decompressed directory:
```
 cd Emojicode-1.0-beta.2-Linux-x86_64
```
Run the installer therein:
```
 sudo ./install.sh
```
And answer y to any questions when prompted.

If you then run

emojicodec

without any command-line arguments, you should see:

👉  Option 'file' is required

If not, best to retry these steps!

Compiling

Execute

code hello.🍇

to create a new file called hello.🍇. (You’ll probably find it easier to copy/paste than type manually.) That’s right, Emojicode uses a file extension of .🍇!

Next, copy/paste this now-familiar program into the file:

🏁 🍇
  😀 🔤hello, world🔤 ❗️
🍉

Then compile the program with:

emojicodec hello.🍇

And run it with:

./hello

You should see a familiar greeting. If not, best to retry these steps!

Understanding

To understand this new language, start by reading Emojicode’s guide. Then answer each of the below.

(1 point.) What is 🏁 similar to in C?

(1 point.) What are 🍇 and 🍉 similar to in C?

(1 point.) What is 😀 similar to in C?

(1 point.) What are 🔤 and 🔤 similar to in C?

(1 point.) What is ❗️ similar to in C?

Keeping Emojicode’s guide still in mind, consider the program below. You might find it helpful to copy/paste it, too, into a .🍇 file so that you can compile and run it a few times.

🏁 🍇
  🍿 1 2 3 4 5 6 7 8 9 10 🍆 ➡️ 🖍️🆕 numbers
  🐹 numbers ❗️
  😀 🔡 🐽 numbers 0 ❗️ ❗️ ❗️
🍉

(2 points.) In emojicode/6.py, re-implement the program in Python.

Let’s now stray a bit from the guide. Consider the program below. You might find it helpful to copy/paste it, too, into a .🍇 file so that you can compile and run it. You might also find it helpful to skim Emojicode’s package index for strings.

🏁 🍇
  👄 🔤🤷 🔤❗️
  🆕 🔡▶️👂🏼 ❗️ ➡️ s
  👄 🔤👋 🔤 ❗️
  😀 s ❗️
🍉

(2 points.) In emojicode/7.py, re-implement the program in Python.

Finally, consider the program below. You might find it helpful to copy/paste it, too, into a .🍇 file so that you can compile and run it. You might also find it helpful to skim Emojicode’s language reference for control flow.

🏁 🍇
  🔂 i 🆕⏩ 10 0 -1 ❗️ 🍇

(2 points.) In emojicode/8.py, re-implement the program in Python.
