Jui

Jui is a general purpose Turing Complete minimal programming language in Bangla. This is written fully in C with the help of a parser generator (https://github.com/Irtiaz/IrParseTableGenerator and https://github.com/Irtiaz/IrParser) and a lexer generator (https://github.com/Irtiaz/IrLex)

Installation

The source code (main.c) and the parse table file (parse-table.txt) along with the lexical analysis rules file (rules.txt) has to be put together and made with a C compiler (a sample Makefile is provided). The grammar for the language is provided (language-grammar.txt). If you want to bring some changes to the grammar you are welcome to do so. Make sure to compile the grammar with the parse table generator (https://github.com/Irtiaz/IrParseTableGenerator)

Syntax

variables

Variable usage is just like C. Currently all the variables are integers. Remember, every variable is an array. a = 0 would just mean a[0] = 0.The sizes of the arrays can grow indefinitely. This is a perfectly valid code -

a = 10
a[100] = 4

This would mean the array a has 10 in it's beginning and 4 at index 100. Indexing starts at 0. Note that the code mentioned above is analogous to

a[0] = 10
a[100] = 4

Memory allocation and deallocation is completely automatic!!

operators

Most operators are like C. Except for the relational operators and the modulo operator Modulo operator is done by the keyword vagshesh a < b is replaced by a, b er choto a == b is replaced by a, b er soman a > b is replaced by a, b er boro

That's all! Wait then how do we write != or <=? a <= b can be written as a, b er boro na a >= b can be written as a, b er choto na a != b can be written as a, b er soman na Basically the ! operator is replaced by the keyword na So a C expression like !(!(a < b)) would look like a, b er choto na na in Jui

Increment or decrement operators and bitwise operators are not supported

output and input

write an expression to the terminal with the likho command. For example

likho (a + 2) vagshesh 10

read a variable from the terminal with the poro command. For example

poro a[2]

conditional

The syntax for a conditional statement is explained below with an example

jodi a, 10 er soman hoy taile
	a = a + 5
koro
noile jodi 2, 3 er choto na hoy taile
	a = 0
koro
ar noile
	a = 1
koro

conditions can be joined together with othoba for logical OR and ebong for logical AND

loops

The syntax for a loop is -

jotokkhon <condition> thake totokkhon
	<statements>
koro

for example,

jotokkhon i, n er choto thake totokkhon/
	i = i + 1
koro
