BubbleLang

BubbleLang is designed by PSTF.

Name

I don't know why, but I like this name because I like the shape of circle and sphere.

Sources of inspiration

I let my 文心一言 to generate an Esolang, and I inspired from that.

I'm also inspired from Python and C++.

Syntax

Basic Commands

Command Table

CMD	Meaning
print(*args(, end='\n'))	Print something with the end symbol. If you didn't define the end symbol, then it will end with \n.
input(__prompt)	This didn't be an isolated command. Get user input and then assign to a variable. The prompt of input will be __prompt. Every input occupies one line. Inputed things will store into a string.
var name(: type) (= value)	This defines a variable called name and assign value to it. If you omitted the type, then you must assign something to the variable. If you ommited the value, then you must indicates its type.
var = value	Simple Variable Assign.
type(var)	Change the variable to the "type".
#	Inline comment.
from lib import module_name	Import module_name from lib. Use * replace module_name to import everything.

Advanced commands

Multiline comment

Conditional statement

if expr1:
    code1
(
elif expr2:
    code2
elif...
elif exprN:
    codeN
else
    codeSUCC_N
)

Bracketed things can be omitted.

An if-elif-else statement can has 114514 "elif"-s, but can only has ONE "else".

Both of elif and else must pair with if.

Function defination

function your_function_name(*args, **kwargs):
    somecode
    (return (somereturnvalues))

Object defination

class your_class_name
    var attr_1: type
    function __init__(self):
        initialization
    funtion func1(self, *args, **kwargs):
        code

var object: your_class_name

Types

nil

This type is the blank type. When you want to define a blank variable, you can use this.

bool

A logical value which has only 2 states: True and False.

Every zero-value(such as 0, 0.0, 0j, "", [], {}) will return False, otherwise return True.

False will convert to 0, and True will convert to 1.

Numeric Variables

int

Simply an integer, range is ℤ.

float

Simply a decimal, range is ℝ.

comp

Simply a complex number, range is ℂ.

Format: real+imagj

Character variables

char

A single character. It is quoted by single quotation mark.

str

A string, as the name suggests, is made up of many characters. Both the string type and the character type support escaping characters, which are escaped by backslashes. In particular, lowercase n means new, lowercase t means horizontal tab, lowercase a means character 7 (BEL character), lowercase b means character 127 (DEL character), the number zero represents character 0 (NUL character), uppercase Q means double-quote, lowercase q means single-quote, variable wrap in a brace means output this variable(Only support by f string).

1. \n ---- newline
2. \t ---- horizontal tabulation
3. \b ---- backspace
4. \a ---- alarm
5. \0 ---- NULL
6. \x[hhhh] ---- Hexadecimal character
7. \[ddddd] ---- Decimal character
8. {var} ---- output the variable
9. \Q ---- double quote
10. \q ---- single quote
11. \N[character name] ---- output the character named [character name]. For example, Cyrillic capital letter El outputs Л, Sinhala letter Kantaja Naasikyaya outputs ඞ, CJKV Unified Ideogram 0x3400 outputs 㐀, and so on.

You can also add f in front of the string to make a formatted string.

When you try to int-ize a string, then you'll get the integer that is the string, except there are something invalid for integer.

Multiline String

Multiline String is quoted by sextuple quote("""). It didn't need the escape character.

Constants

They're defined by const name = value. Once they're defined, they can't change unless delete it then redefine it.

Pointer

Add asterisk after the type.

Loop

forloop

for element in list: 
    code

whileloop

while expr:
    code

Error Handle

try:
    Code_that_may_throw_an_error
except Exception:
    Code1
(
else:
    Code2
finally:
    Code3
)

Caption text

Exception	Causing
SyntaxError	Syntax is not standardized
NameError	Referenced on an undefined thing
TypeError	An incompatible method that works for another type is used for a variable of one type
CalculationError	Division with a divisor of 0, functions that use out-of-range parameters (e.g., arcsin(2))
ValueError	The value passed in may be invalid or illegal
FileError	Trying to read the file that didn't there

Example

More examples are available at /Algorithm and /Examples.

Hello, world!

print("Hello, world!")

A+B Problem

var a = input()
var b = input()
a = int(a)
b = int(b)
var c: int
c = a + b
print(c)

Truth Machine

<?
This is the Truth Machine.
It requires a programming language that can input, output, judge, terminate, and loop.
Generally speaking, if a programming language can write a the Truth Machine, it can already be a TCPL.
?>
var a = input()
a = bool(int(a))
if a:
    while a:
        print("1\n")
print("0")

Disan Count 2.0

<?
This is the Disan Count.
It requires a programming language that can input, output, judge, arithmetic, and loop.
Generally speaking, if a programming language can write a the Disan Count, it can already be a TCPL.
?>
var a = input()
a = int(a)
for i in range(1, a + 1, 1):
    if i % 2 == 0:
        print(f"{i} is even!")
    else:
        print(f"{i} is odd!")
