Leap Year @ Hacktober Fest 2024

Happy Hacktoberfest!

This is code in ACPUL programming language to determine whether a year is a leap year.

You can see the code in the repo at https://github.com/andrewhoyer/leap-year/tree/main/ACPUL

NOTE: Use Python syntax highlighting for ACPUL in Sublime Text or Markdown.

Running tests from CLI

To run test from CLI just use acpul interpreter with -i <path> for the source directory and -e <formulaId> with the number of the formula to execute:

acpul -i . -e 2024100

Running tests inside ACPU

Just copy the file to the ACPU project directory and create a new formula node in the bootloader:

# Create by formula number
node.new.this.ex(r0, 2024101, 0);
# Or create by formula name
node.new.this.ex(r0, NNN(eternal.hacktoberfest.test), 0);

### 2024100 leap.year

# The formula defines the leap year API

_ @sys.time;


#
# Define function 'is.leap.year'
# Returns true if it is a leap year
#
is.leap.year {
  # year
  year _0; # input param 0

  # Define variants
  mod4 mod(year,4)==0;
  nmod100 mod(year,100)!=0;
  mod400 mod(year,400)==0;

  # Calc a summ
  0!=((mod4*nmod100)+mod400);
};

# Aliases for programming styles
is_leap is.leap.year(__);
isleap is.leap.year(__);
isLeap is.leap.year(__);
calendar.isleap is.leap.year(__);


# THE TEST FORMULA BELOW
#      #########
#        VVVVV
#         VVV
#          V

### 2024101 eternal.hacktoberfest.test

# Import 'leap.year' formula
_ @leap.year;

# Define date manually
year = 2024;

# Get the current date. Year returns to o2 register
get.time.date;
year = o2;

# Call is.leap.year to determine if it is a leap year
leap = is.leap.year(year);

# Show the result below

#
# Display values for UI
#
info {
  # Use UI utilities
  _ @4; 

  # Show the value
  
  lbl0 0; val0 0; ui.value4(lbl0,val0,100,50+0,1, Is.this.year.a.leap.year, leap);
  lbl0 0; val0 0; ui.value4(lbl0,val0,100,70,1, Check.year, year);

  # More tests and values
  lbl0 0; val0 0; ui.value4(lbl0,val0,100,100+20,1, Is.y1900.a.leap.year, isleap(1900));
  lbl0 0; val0 0; ui.value4(lbl0,val0,100,100+40,1, Is.y2000.a.leap.year, isleap(2000));
  lbl0 0; val0 0; ui.value4(lbl0,val0,100,100+60,1, Is.y2023.a.leap.year, isleap(2023));
  lbl0 0; val0 0; ui.value4(lbl0,val0,100,100+80,1, Is.y2024.a.leap.year, isleap(2024));
};

info;

# Output to console for CLI

console.output {
  watch(leap);
