Introduction

Calico is a custom language i made in mid 2021 and is still developing. This idea was first proposed in 2020? 2019? i forgot. Calico has borrowed a lot of thigs from python so it is reasonably easy .

Currently Calico supports(V0.2):

• Simple arithmetic
• Tuples
• Function calls
• Print input builtins
• Multi-line code
• Strings
• Comparison operators
• Bools
• If else elif statements
• Func def
• While loops

Getting started

Hello world

For most languages hello world is simple, and calico is one of them.

First we are introduced to the print function. it prints out everything in it. print

Next we are introduced to str. It's not a class, classes are supported in the next version "Hello world!"

print("hello world")

Math

Math in Calico is the same as any other language.

If's, Else's, Elif's

Calico handels if's like any other language

syntax:

if CONDITION CODE

calico handels code blocks with brackets

{
  a = 1 + 2
}

elifs are the same as

else {
  if ...
}

example of if's

if {
  a > b
} {
  print(a)
}

Multi-line code

Calico handels Multi-line Code using ;.

exemples of multi-line code

a = 1;
b = 2;
if {
  a > b
} {
  print("a is more than b")
} else {
  print("a is more than b")
}

Functions

Defining functions

Lets say we have a simple function foo. this function will print out "Foo bar" everytime we call it

to define this function we type the keyword method the type the function name foo
then we we type an empty tuple after that we call the print method to print "Foo bar" to the console

It should look like this

method foo() {
  print("Foo bar")
}

Calling functions

before callicng your custom function, there are a few builtin methods you shpuld learn

print, prints input, get input from user int, turns str to int get_prec, gets the floating point precision set_prec, sets the floating point precision

to call a custom function first type the name of the function,/ then write a tuple with all of the parameters of the function

example

foo()

While loops

syntax WHILE CONDITION CODE
example

a = 0;
while {
  a < 10
} {
  print(a);
  a = a + 1
}
